NASA astronaut and Expedition 68 Flight Engineer Frank Rubio is pictured inside the cupola, the International Space Station's "window to the world," as the orbiting lab flew 263 miles above southeastern England on Oct. 1, 2022.

The planet TRAPPIST-1e lies in its star’s Goldilocks zone, where water remains liquid – and an analysis suggests it might have a nitrogen-rich atmosphere like Earth’s

"The American people deserve maximum transparency from the federal government on sightings, acquisitions and examinations of UAPs and whether they pose a potential threat to Americans' safety."

A strange kind of geometry governs how particles move inside matter. Now, for the first time, physicists have uncovered its full shape – and it could transform how we design materials

What role can the relationship between oxygen (O2) and ozone (O3) in exoplanet atmospheres have on detecting biosignatures? This is what a recent study submitted to Astronomy & Astrophysics hopes to address as an international team of researchers investigated novel methods for identifying and analyzing Earth-like atmospheres. This study has the potential to help scientists develop new methods for identifying exoplanet biosignatures, and potentially life as we know it.

When NASA's OSIRIS-REx spacecraft returned from its mission to asteroid Bennu in 2023, it brought back more than just ancient space rocks, it delivered answers to puzzles that have baffled astronomers for years. Among the most intriguing questions was why asteroids that should look identical through telescopes appear strikingly different colours from Earth.

The recent discovery of the third known interstellar object (ISO), 3I/ATLAS, has brought about another round of debate on whether these objects could potentially be technological in origin. Everything from random YouTube channels to tenured Harvard professors have thoughts about whether ISOs might actually be spaceships, but the general consensus of the scientific community is that they aren’t. Overturning that consensus would require a lot of “extraordinary evidence”, and a new paper led by James Davenport at the DiRAC Institute at the University of Washington lays out some of the ways that astronomers could collect that evidence for either the current ISO or any new ones we might find.
