go to infinity & beyond

Do you know about Astronomy’s exciting new video series? It’s called Infinity & Beyond, and explores a huge range of astronomical topics and exactly what we know about them in this golden age of cosmic research. Commenced in mid-2020, our series has thus far produced 20 really informative episodes that you can use to keep up with the latest scientific findings. The series also enables you to enjoy your hobby of observing the sky, making the most of the time you have under the stars. Infinity & Beyond is hosted by a young, knowledgeable, and very enthusiastic astronomy outreach expert, Abigail Bollenbach. An Oklahoma native and a college student looking toward an astronomical career, she is a winner of the Astronomical League Horkheimer/Smith Youth Award. Abby is also an Explore Alliance Ambassador…

We welcome your comments at Astronomy Letters, P.O. Box 1612, Waukesha, WI 53187; or email to . Please include your name, city, state, and country. Letters may be edited for space and clarity. Remembering Apollo 14 I wanted to thank you for the wonderful Apollo 14 retrospective articles in your May 2021 issue. I had the distinct honor of not only meeting Dr. Edgar Mitchell many times but teaching his son, Adam, in my astronomy class in Boca Raton, Florida. Dr. Mitchell was very gracious in helping my class during our annual Kennedy Space Center field trip. We were able to visit and get a group picture in front of the Apollo 14 command module, Kitty Hawk. Your article brought back some great memories! — Lachlan Mackay, Boca Raton, FL What in the…

a chaotic cosmic tapestry

EVERYTHING YOU NEED TO KNOW ABOUT THE UNIVERSE THIS MONTH This vivid scene resembles a Jackson Pollock painting — an abstract expression of line and color splashed across the center of our Milky Way Galaxy. But another analogy for the physics at work might be a tapestry woven by magnetic threads. The broad regions of color (orange, green, and purple) represent X-ray emission with different levels of energy observed by NASA’s Chandra X-ray Observatory. The narrow filaments in gray are radio observations from the MeerKAT array in South Africa. Many of these complex structures — some of which appear both in X-rays and radio waves — are produced by plumes of superheated gas and the twisted strands of magnetic fields near the center of our galaxy. Where these plumes collide, their magnetic threads…

HIGH-ENERGY HAUL The Large High Altitude Air Shower Observatory in China’s Sichuan province has detected the most energetic photon ever seen. The photon slammed into Earth’s atmosphere with an energy of 1.4 quadrillion electron volts (1.4 PeV). FARSIDE VIEW A proposal to use rovers to build a radio telescope inside a crater on the Moon’s farside won a $500,000 NASA grant to study its feasibility. The 0.6-milewide (1 km) wire-mesh dish would be shielded from human-made interference. FAREWELL, BENNU NASA’s OSIRIS-REx mission departed asteroid 101955 Bennu on May 10 to begin its return journey to Earth. In October 2020, the craft collected at least 0.9 pound (400 g) of samples from Bennu’s surface.…

china’s first mars rover touches down

At 7:18 p.m. EST on May 14, a six-wheeled rover the size of a small car plunged into Mars’ thin atmosphere, braking with a series of parachutes and retro-rockets. In a picture-perfect landing, Zhurong touched down on the lava plains of Utopia Planitia and stretched out its solar panels, making China the second country to successfully land and operate a rover on Mars. As the news reached the Beijing Aerospace Control Center, where it was the morning of May 15, blearyeyed engineers erupted in thunderous applause. With its successful touchdown, Zhurong, named for an ancient Chinese god of fire, has now vaulted China into the hallowed ranks of nations with a multiplanetary presence. MAKING HISTORY Zhurong’s journey began in July 2020, when it launched aboard the Mars-bound Tianwen-1 spacecraft. The mission reached the…

SPLISH SPLASH Nearly six months after hitching a ride to the International Space Station (ISS) aboard a SpaceX Falcon 9 rocket, NASA’s first commercial crew — carried by a SpaceX Crew Dragon capsule — safely splashed into the Gulf of Mexico near the coast of Panama City, Florida, on May 2. COSMIC HUM Voyager 1, which launched in 1977 and is now near the edge of the solar system, detected a faint but persistent murmur coming from the relatively empty space between stars. According to new research, the hum is from low-level, long-lasting vibrations in interstellar plasma. FLOATING FILM Russia’s Roscosmos space agency recently announced plans to send a director and actress to the ISS to shoot a movie tentatively titled Challenge. The expedition is expected to launch from Baikonur Cosmodrome aboard a Soyuz spacecraft…
