The first images from the James Webb Space Telescope have arrived! They are starry, stellar, and dazzling images of never before seen nebulae and star-forming regions of the universe. The images are quite the upgrade from the images taken by the Hubble Space Telescope, showing deep space in exquisite detail. U.S. President Joe Biden released the first images on Monday, June 11, 2022.

The James Webb Space Telescope was successfully launched into space atop an Ariane 5 rocket on Dec. 25, 2021. The James Webb Space Telescope, abbreviated JWST, is an observatory replacing some capabilities of the Hubble Space Telescope. The Hubble Space Telescope is a powerful orbiting telescope that provides sharp images of heavenly bodies. Webb’s main mirror is 6.5 meters (21 feet) across. Webb will have about seven times larger light-collecting area than Hubble. However, Webb is designed to study infrared light, a type of light wave with longer wavelengths than those of visible light. Thus, Webb will not replace Hubble’s visible light capabilities.

Webb is a collaboration between the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA), and the Canadian Space Agency (CSA). The Space Telescope Science Institute, which currently operates Hubble, is managing Webb’s science operations. The telescope is named after James Webb, the former NASA administrator who conceived and directed the Apollo program for most of the 1960’s. Webb has been a work in progress since 1996 and its deployment was delayed many times over the years.

The Webb telescope will enable scientists to study the history of the universe, nearly all the way back to a cosmic explosion called the big bang. It will collect information on the first stars and galaxies that formed after the big bang, the formation of planetary systems, and the evolution of planets within the solar system.

The first images NASA released show a star-forming region in the Milky Way called the Carina Nebula captured in infrared light. A nebula is a cloud of dust particles and gases in space. The term nebula comes from the Latin word for cloud. Other images show the Southern Ring Nebula in near-infrared light and mid-infrared light. This image shows the remains of a white dwarf star, similar to our Sun.

Webb is equipped with several specialized cameras and spectrometers, instruments that spread out light into a band of wavelengths called a spectrum. Astronomers can study such a spectrum for signs of light given off by certain molecules or atoms. Webb also has a primary (main) mirror made of many segments, which was folded up to fit in the launch rocket. The mirror is to unfold and adjust to its proper shape before Webb reaches its permanent orbit. A large sun shield, about the size of a tennis court, will help prevent the infrared light from the sun, and the reflected sunlight from Earth and the moon, from interfering with observations. Webb is specifically designed to cool down its sensors to gather better data.

After launch, Webb traveled to a Lagrange point, a special point in space where the gravitational pulls of the sun and Earth are in balance. Webb is to remain there, 930,000 miles (1.5 million kilometers) from Earth, observing the skies for up to 10 years. During its primary mission, Webb is designed to be the world’s premier space observatory, used by thousands of astronomers worldwide.

The first image of Sagittarius A*, the supermassive black hole at the center of our galaxy.

Finally, the faceless monster lurking at the center of our galaxy has been photographed. Sounds like science fiction? It’s true! On Thursday, May 12, scientists with the Event Horizon Telescope (EHT) team published a photograph of Sagittarius A* (saj uh TAIR eeuhs AY star). Sagittarius A* is a supermassive (huge) black hole in the center of our galaxy, the Milky Way.

A black hole is a region of space whose gravitational force is so strong that nothing can escape from it, not even light. The event horizon is the “point of no return” for a black hole: Anything that crosses this horizon is sucked into the black hole forever. Supermassive black holes at least a million times more massive than the sun lurk at the center of many galaxies.

The EHT is a global network of ground-based telescopes that use a technique called radio interferometry to produce images of black hole event horizons. The collection of radio telescopes participating in the EHT project stretches from Hawaii to Europe and all the way south to Antarctica. Several dozen of the world’s leading observatories and universities contribute to the project. Supercomputers process the image data using special algorithms in a process called correlation.

Astronomers began using the EHT to make observations of Sagittarius A* in 2017. In 2019, the EHT released an image it had captured of the event horizon surrounding the supermassive black hole at the center of the Messier 87 galaxy (M87*). It was the first time an event horizon had been photographed.

If light can’t escape a black hole, how did EHT photograph M87* or Sagittarius A*? Technically, it didn’t: all black holes are invisible and cannot be directly photographed. But matter trapped in orbit near the event horizon is extremely energized and emits large amounts of light. The black hole lurks in the circular “shadow” within the halo of high-energy matter. Thus, the EHT can take a picture of a black hole much as we can take a picture of a doughnut hole.

Despite being closer to Earth, Sagittarius A* was still harder to image than M87*. Sagittarius A* is still 27,000 light-years from Earth. It’s also more than 1,000 times smaller and less massive than M87*. So, although the high-energy matter is orbiting both black holes at about the same speed, the matter completes an orbit around Sagittarius A* in a matter of minutes. Furthermore, Sagittarius A* is “quieter”: it emits far less energy than M87*. All these factors made it difficult for EHT to capture an image of it.

Now that EHT has imaged two black holes, astronomers can compare them. Both look remarkably similar, despite their differing sizes. Both confirm what was predicted by Einstein’s theory of relativity. But plenty of questions remain. For example, are the “blobs” in the picture actual elements, or are they artifact of the correlating process? The EHT is also considering the feasibility of creating a short video of Sagittarius A* by stringing together multiple consecutive images. And plenty more supermassive black holes are waiting for their photographic debut. A major observation campaign that concluded earlier this year featured even more telescopes. Expect more exciting results soon regarding these most extreme objects in the universe.

Well, not exactly. Scientists recently grew plants in lunar soil for the first time in history. The lunar soil, also called moon dust, was brought back from three Apollo missions. Scientists from the University of Florida planted thale cress in the moon dust and compared the growth to materials found on Earth’s surface, such as volcanic ash. Thale cress is a small, bitter-tasting plant similar to broccoli, cauliflower, and kale. After two days, the seeds had germinated (grown). However, the plants in moon soil did not thrive compared to the plants in Earth soil after six days.

Lunar soil is very different from the soil on Earth. Soil is the mixture of minerals, organic matter, and other materials that covers most of Earth’s land. Soil is a storehouse of nutrients and the decayed remains of organisms (living things). Lunar soil is more dusty and is not made up of decayed organisms, so it does not contain as many nutrients compared to soil found on Earth. Impacts of micrometeoroids (tiny meteoroids‘) grind the surface rocks into a fine, dusty powder known as regolith. Regolith overlies all the bedrock on the moon. Because regolith forms as a result of exposure to space, the longer a rock is exposed, the thicker the regolith that forms on it.

National Aeronautics and Space Association (NASA) granted the scientists 12 grams of lunar soil for the experiment because it is precious and cannot be wasted. The soil brought back from Apollo 11 was not as strong as the soil brought back from Apollo 12 and 17. The scientists believe soil from Apollo 11 was damaged by cosmic rays and radiation from solar wind on the moon’s surface. Scientists have already started planning where they could find better moon soil where lava flow has enriched the soil.

For years, scientists have wondered whether the moon could support life. If humans were to survive on the moon permanently, they would need to grow plants for food. Although the experiment did not prove that the moon could sustain life, it gives hope that there could be vegetation on the moon someday. We are one step closer to growing an herb garden on the moon!

American astronaut and geologist Jessica Watkins is making history this month. She is the first Black woman selected for an extended mission in space. Watkins and three other astronauts launched aboard a new SpaceX Crew Dragon spacecraft named Freedom atop a Falcon 9 rocket on April 27, 2022. Once the crew arrives, they will work and live aboard the International Space Station (ISS). The ISS is a large, inhabited Earth satellite that more than 15 nations are operating in space. Watkins is set to work aboard the station for six months. On the ISS, she will work at the microgravity laboratory and serve as the team’s mission specialist.

Jessica Andrea Watkins was born in Gaithersburg, Maryland, on May 14, 1988. Her family later moved to Lafayette, Colorado. She enrolled at Stanford University in California, in 2006.  Watkins led Stanford’s rugby team to win the 2008 national championship. Watkins was a member of the United States Women’s Eagles Sevens Rugby team, competing in the 2009 Women’s Sevens Rugby World Cup in Dubai. Watkins earned her bachelor’s degree in geological and environmental sciences from Stanford University in 2010.

Watkins studied and worked extremely hard to reach her new career in space. Watkins earned a doctorate degree in geology at the University of California, Los Angeles, in 2015. Watkins conducted post-doctoral research at the California Institute of Technology (Caltech). At UCLA, she studied landslides on Mars. At Caltech, she helped plan missions for the National Aeronautics and Space Administration (NASA) Curiosity rover.

As an undergraduate, Watkins participated in an internship for NASA at the Ames Research Center outside of San Jose, California. She compared simulated Martian soils with data gathered by the Phoenix Mars Lander.  In 2009, Watkins served as the chief geologist for a simulated mission at the Mars Desert Research Station outside of Hanksville, Utah. As a graduate student, she interned for the Jet Propulsion Laboratory in Pasadena, California. In 2017, Watkins was selected for astronaut training. In 2019, Watkins participated as an aquanaut in a simulated space mission at the NASA Extreme Environment Mission Operations (NEEMO) Aquarius habitat, on the ocean floor off the coast of Key Largo, Florida. NASA has also selected Watkins as a crew member for the Artemis mission to the moon’s surface.

Ham, chimpanzee sent into space

When thinking of Project Mercury, students likely point to the first astronauts. Mercury was the first National Aeronautics and Space Administration (NASA) project to send humans into space. They were some of the first beings to traverse the stars aboard a rocket and orbit the Earth, but that’s not all. Primates are the group of animals that includes monkeys, apes, and human beings. The first primate in space wasn’t cosmonaut Yuri Gagarin—it was a brave chimpanzee named Ham.

Ham was one of several animals used in Project Mercury. The Mercury capsule was tested with chimps and other primates before launching humans into space. Chimpanzees were used because they are intelligent and closely related to humans, with the ability to be trained to perform simulated spacecraft operations. Ham helped to prepare the U.S. space program for human space flight.

Ham was born in the 1950’s in a forest in Cameroon (then French Cameroon). The U.S. Air Force had chimps captured from the forest and sent to the United States. In 1959, 40 chimps were enrolled in the “School for Space Chimps” on the Holloman Air Force Base in Alamagordo, New Mexico. They were given the nickname astrochimps and trained for spaceflight. Another astrochimp, Enos, later became the first and only chimpanzee to orbit Earth.

At just 3 years old, Ham, also known as Subject 65, excelled at his tasks. The nickname Ham stood for Holloman Aerospace Medical Center, where the chimps were trained. Ham learned to pull levers when cued by a blue light. The chimps were trained to spend long periods in a chair and were subjected to extreme acceleration forces and microgravity, the sensation of weightlessness experienced by astronauts in space. After 18 months, Ham and five other well-performing chimps were sent to Cape Canaveral, Florida, in 1961 for an experimental flight. The brief suborbital flight was to test the environmental controls, life support, and recovery systems of the Mercury spacecraft in weightless conditions.

On Jan. 31, 1961, a Mercury-Redstone 2 rocket took off with Ham as its passenger. He was strapped into a “couch” in the small, pressurized capsule. The craft briefly lost air pressure during the flight, but Ham’s capsule saved him from harm. The rocket traveled 400 miles (640 kilometers) and peaked around 160 miles (250 kilometers) above Earth’s surface. It went higher and faster than NASA’s plan, which called for a peak of 115 miles (185 kilometers) altitude and a top speed of 4,400 miles (7,000 kilometers) per hour. The rocket actually reached speeds of 5,800 miles (9,300 kilometers) per hour.

The flight lasted about 16 ½ minutes. Ham experienced 6 ½ minutes of weightlessness. Ham was dressed in a spacesuit and waterproof pants. He was hooked up to sensors that recorded his body temperature, breathing, and heart rate. The flight was probably extremely distressing to Ham. Despite the stress of weightlessness and crushing acceleration forces, Ham was able to pull levers in response to flashing blue lights. He proved that astronauts could perform motor functions under the stresses of spaceflight. His capsule splashed down in the ocean and was recovered 130 miles (210 kilometers) from its target. The capsule was taking on water, and Ham had been waiting in distress for hours.

After the flight, Ham was relocated to the National Zoological Park in Washington, D.C., in 1963. After 17 years living alone there, Ham joined other chimps at the North Carolina Zoo in Asheboro in 1980. Ham died on Jan. 18, 1983, at the age of 25, young for a chimp. His remains were buried by the U.S. Air Force at the International Space Hall of Fame in the Museum of Space History in Alamogordo. His skeleton was kept for scientific study at the National Museum of Health and Medicine in Washington D.C. NASA eventually stopped sending non-human primates into space in the 1990’s, in part due to pressure from animal rights groups.

The Space Telescope Science Institute, which currently operates Hubble, is to manage Webb’s science operations, which are expected to begin in summer 2022.

The Parker Solar Probe approaches the sun in this artist’s depiction. The probe’s path takes it nearer to the sun than any other human-made object, allowing it to make close-up observations of solar activity.
NASA

The Parker Solar Probe has done the unthinkable. It became the first spacecraft to touch the sun! Scientists reported the announcement on Dec. 14, 2021, at the press conference at the 2021 American Geophysical Union Fall Meeting in New Orleans, Louisiana. The probe was built and operated by the Johns Hopkins Applied Physics Laboratory. The probe flew through the upper atmosphere of the sun, called the corona, to collect samples. The samples will allow scientists to understand more about the sun, just like landing on the moon paved the way for scientists to learn about the moon.

The National Aeronautics and Space Administration (NASA) launched the Parker Solar Probe in 2018. The probe completed its first orbit of the sun in 2019. The probe is the fastest human-made object in the solar system. The sun’s gravity is expected to accelerate the probe to extreme speeds of up to 430,000 miles (700,000 kilometers) per hour. Three years after the launch, the probe has arrived at the sun.

The goals of the mission are 1) to study how energy and heat flow through the corona; 2) to gather information on plasma (the gaslike substance the sun is composed of) and magnetic fields near the sun; and 3) to learn more about how high-energy particles travel outward from the sun.

It uses a set of instruments known as FIELDS, which has antennas to measure electric fields and magnetometers to measure magnetic fields. The probe is also equipped with a pair of cameras to capture images of the sun. The probe carries various instruments for studying particles in the solar wind—that is, the continuous flow of particles from the sun.

The sun’s corona can be as hot as 4,000,000 °F (2,200,000 °C). Because of the corona’s low density (concentration of matter), the Parker Solar Probe will not experience the sun’s most intense heat. However, it will encounter temperatures of up to 2,500 °F (1,377 °C)—hotter than lava from a volcano.

The Parker probe is planned to approach the sun 24 times by the mission’s end. Hopefully, the Parker probe can stand the heat and gather more information about the corona and solar winds.

Do you know someone who listens to heavy metal music? Maybe you have friends who like to wear black clothing and bang their heads to loud tunes. Perhaps you have an uncle who’s into Ozzy Osbourne or Van Halen. You may know someone who’s pretty metal, but that person is probably an absolute creampuff compared with the heavy metal planet recently discovered by German scientists.

The planet, designated GJ367b, is an exoplanet, a planet orbiting a star beyond our solar system. It orbits a red dwarf star some 31 light-years from Earth in the southern constellation Vela, the Sails. One light-year is this distance light travels in one year, about 5.88 trillion miles (9.46 trillion kilometers).

At about 3/4 the size of Earth, GJ367b is the smallest exoplanet yet discovered. But, that does not mean that it is a lightweight. The exoplanet has a density of 8 grams per cubic centimeter, compared with about 5.5  grams per cubic centimeter for Earth. This extreme density suggests that GJ367b is the most metallic planet yet discovered. It probably consists mostly of an iron core, perhaps surrounded by a thin layer of rock.

The planet’s density is not its only extreme characteristic. The planet orbits extremely close to its parent star, whipping around the red dwarf every eight hours. If you lived on GJ367b, you might be able to celebrate your birthday about three times each Earth day. You probably wouldn’t like the weather, though. Daytime temperatures reach a sizzling 1500 °C (2700 °F). That’s almost hot enough to melt the planet’s metal. In fact, GJ367b may have an atmosphere composed of evaporated rock.

That scientists were able to learn so much about such a small planet shows just how far the hunt for exoplanets has advanced. Scientists discovered GJ367b using the Transiting Exoplanet Sky Survey (TESS) telescope, announcing the discovery in December. The TESS telescope identifies exoplanets by measuring changes in a star’s light as an orbiting planet transits (passes in front of) it. Scientists hope to learn even more about this heavy metal world with the launch of the James Webb Space Telescope.

After training for 60 years, Wally Funk finally arrived in space this summer. Once a trainee of the First Lady Astronaut Trainees (FLAT’s) program run by a National Aeronautics and Space Administration (NASA) physician back in 1961, Funk passed all the tests and training before the program ended. Although these women, later known as the Mercury 13, were not permitted to become astronauts, Funk never forgot her dream of going to space. She had a distinguished career as a pilot, logging thousands of miles or kilometers in the air and teaching thousands of other pilots, not staying on the ground for too long.

On July 20, 2021, Funk flew on the New Shepard rocket built by the company Blue Origin, founded by American businessman Jeff Bezos. She rode with Jeff Bezos, Bezos’s brother Mark, and 18-year-old physics student Oliver Daemen. The rocket rose more than 100 miles (61 kilometers) straight into the air to the boundary of space. The booster separated from the capsule and landed using its engines. The capsule floated back down to the ground on parachutes. The whole flight lasted about 10 minutes.

At age 82, Funk was at that time the oldest person to travel to space. She surpassed the American astronaut and senator John Glenn, who returned to space in 1998 at the age of 77 aboard the space shuttle. Wally Funk held the record for 85 days. Since then, Candian-born actor William Shatner, 90, traveled to space on Blue Origin’s second suborbital flight on October 13, 2021, claiming the record.

Mary Wallace Funk was born Feb. 1, 1939, in Las Vegas, New Mexico, near Santa Fe. She began her first flying lessons at the age of nine. Funk graduated first in her flying class at Stephens College in Columbia, Missouri, and earned her pilot’s license in 1958. Funk earned her Bachelor of Science degree in secondary education from Oklahoma State University. There, she joined the school aviation team, the Flying Aggies. In 1960, at the age of 21, she was named a flight instructor at Fort Sill in Oklahoma, becoming the first woman flight instructor at a U.S. military base.

After the FLAT’s program ended, Funk continued her career as a pilot and flight instructor. She became the first woman inspector with the Federal Aviation Administration (FAA) in 1971. In 1974, she became the first woman air safety investigator for the National Transportation Safety Board, investigating plane crashes. NASA began accepting women as astronauts in 1978, and Funk applied four times to the agency for astronaut training. She was denied, despite her experience, because she did not have an engineering degree. Undeterred, Funk pursued opportunities for private space travel, purchasing a ticket for a future suborbital flight with space tourism company Virgin Galactic. Earlier this year, Bezos surprised Funk with a seat on Blue Origin’s inaugural crewed flight, fulfilling Funk’s lifelong dream.

It’s not every day that the National Aeronautics and Space Administration (NASA)  launches a new spacecraft. Their latest, named Lucy, was launched Oct. 16, 2021, from Cape Canaveral Space Force Station in Florida. Its mission? Explore the Trojan asteroid belt near the orbit of Jupiter. Lucy doesn’t have a crew, but the craft is equipped with powerful telescopes and cameras to gather information about the mysterious asteroids.

Lucy won’t be taking a direct path to Jupiter’s orbit, however. The spacecraft will use a series of gravity assists to help move it closer to its target. In a gravity assist, a spacecraft uses momentum gained from swinging by a planet to adjust its path and fling it toward a target.

After spending a year orbiting the sun, Lucy will return to Earth’s orbit for its first gravity assist in October 2022. This assist will set it on a course it toward Mars. In 2024, a second gravity assist will send Lucy towards the main asteroid belt, between the orbits of Mars and Jupiter. On this orbit, Lucy’s telescopes and cameras will capture images of asteroid 52246 Donaldjohanson. The probe should arrive at the Trojan asteroid belt by 2027.

Each of the asteroids in the Trojan belt is named after a different hero from the Greek epic the Iliad. The first Trojan Lucy will photograph is Eurybates in August 2027. Eurybates is unique because it has a smaller moon orbiting it, named Queta. Polymele will be photographed in September 2027, and Leucus and Orus will be photographed in April 2028 and November 2028, respectively. After that, Lucy will return to Earth for one more gravity assist. In 2033, Lucy will finish the mission by visiting the Trojan asteroids Patroclus and Menoetius. The spacecraft will remain in orbit around the asteroids, studying the asteroids for as long as it continues to function.

The Trojan asteroids were named after Greek myths, but what about Lucy? Usually, NASA uses acronyms for naming spacecraft. An acronym is a word that uses the first letter of each word in a phrase to create a new word, for example referring to the National Aeronautics and Space Administration as NASA.  In Lucy’s case, however, they named the craft after a fossilized skeleton found in 1974, in Ethiopia. Lucy wasn’t exactly a human – she represented a species of hominin called Australopithecus Afarensis. Hominins are a group of living things that includes human beings and early humanlike ancestors.

The expedition that found the skeleton Lucy was led by the anthropologist Donald Johanson and his student Tom Gray. An anthropologist is a scientist who studies humans and their close relatives. They were looking for fossils, and on Nov. 24, 1974, they found one of the most significant fossils to date. With 40 percent of her recovered, Lucy represents one of the most complete skeletons ever found from her time, dating to about 3.18 million years ago. When the team returned to their camp the night they found the first fossils, they celebrated their finding by listening to music and partying. One of the songs on repeat that night was “Lucy In The Sky With Diamonds,” a song by British rock band The Beatles. Pamela Alderman, a member of the team, gave the fossil hominid they found the nickname “Lucy” after the song. Just as Donald Johanson was the first to discover the fossil Lucy, the spacecraft Lucy will be the first to study asteroid 52246 Donaldjohanson, named in the anthropologist’s honor.
