Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around them, such as asteroids and moons. For most of human history, the only planets our ancestors knew of were those they could see in the night sky. But in the last 30 years, telescopes sensitive enough

Two teams of dedicated amateur astronomers, supported by NASA, have successfully confirmed the existence of a new exoplanet, a "warm Jupiter," using their backyard telescopes. The teams, known as UNITE (UNISTELLAR Network Investigating TESS Exoplanets) and Exoplanet Watch, combined their efforts to validate the discovery of this exoplanet, which is now designated as TIC 393818343 b (also k

An insect that has been navigating using the Milky Way for 130 million years is now inspiring innovations in drone, robot, and satellite navigation systems. The dung beetle, known for its unique ability to steer using the stars, was identified in 2013 as the first species to utilize the Milky Way for nocturnal navigation. Swedish researchers made this discovery, observing that the beetles

Physicians at the Medical College of Georgia at Augusta University are working with Polaris Dawn, the first of the Polaris Program's three human spaceflight missions, to better understand the eye changes many astronauts experience during spaceflight that can leave them with a wide range of symptoms once they return to Earth—from a new need for glasses to significant loss of vision.

The Polaris Program is a first-of-its-kind effort to rapidly advance human spaceflight capabilities while continuing to raise funds and awareness for important causes on Earth.

More than 70% of astronauts experience a phenomenon known as Spaceflight Associated Neuro-Ocular Syndrome, or SANS, according to NASA. The syndrome can have "a constellation of symptoms, including these changes in vision," said Matt Lyon, MD, director of the MCG Center for Telehealth.

Astronauts can experience other maladies as well when , such as , shift, which can lead to structural changes in the brain.

"The changes start happening on day one," said Lyon, who is also the J. Harold Harrison M.D. Distinguished Chair in Telehealth.

Water plays a crucial role in human survival on the lunar surface, thus attracting extensive research attention. Prof. Wang Junqiang's team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS) has recently developed a new method of massive water production through a reaction between lunar regolith and endogenous hydrogen.

Research results of previous lunar explorations, like the Apollo and Chang'E-5 missions, have revealed the widespread presence of water on the moon. However, the in lunar minerals is extremely low, ranging from 0.0001% to 0.02%. It remains challenging to extract and utilize water in situ on the moon.

"We used lunar regolith samples brought back by the Chang'E-5 mission in our study, trying to find a way to produce water on the moon," said Wang.

Space missions are getting more complex—lessons from industry can inform satellite and spacecraft management in orbit

Most space mission systems historically have used one spacecraft designed to complete an entire mission independently. Whether it was a weather satellite or a human-crewed module like Apollo, nearly every spacecraft was deployed and performed its one-off mission completely on its own.

But today, organizations are exploring missions with many satellites working together. For example, SpaceX's Starlink constellations include thousands of satellites. And new could soon have the capability to link up or engage with other satellites in orbit for repairs or refueling.

Some of these spacecraft are already operating and serving customers, such as Northrop Grumman's mission extension vehicle. This orbiting craft has extended the lives of multiple communications satellites.
