When the JWST finally began its long-awaited science operations in July 2022, there was a long list of targets awaiting its attention. Scientists compete for observing time by submitting proposals,

The closest technological species to us in the Milky Way galaxy could be 33,000 light years away and their civilization would have to be at least 280,000 years, and possibly

Comet 3I/ATLAS is the third ISO ever detected. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station on 1 July 2025. It’s traveling through the inner solar

In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves that resonate inside it. This technique, called helioseismology, revealed a

Tiny red objects spotted by NASA’s James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe—and may represent an entirely new class

At an internal staff briefing last week, acting NASA Administrator Sean Duffy declared the United States has a “manifest destiny to the stars,” linking this to the need to win

Binary star systems are not rare. Neither are systems where one star is a remnant like a white dwarf or neutron star, and its companion is on the main sequence.

While the early climate of Mars remains an open question, a new study suggests that its atmosphere may have been hospitable to life due to volcanic activity that emitted sulfur

TRAPPIST-1 is a red dwarf star located about 40 light years away that hosts seven Earth-sized rocky planets, with at least three orbiting in the habitable zone where liquid water

The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems might
