For decades, the search for alien life has revolved around a narrow ring around stars where liquid water could exist on a planet’s surface. That “habitable zone” remains important, but astronomers are ...

Interstellar comet 3I/ATLAS sweeps past Mars as NASA’s orbiters and Perseverance reveal fresh clues about its chemistry and ...

NASA has long captured the imagination of humanity with its ambitions. We reached the moon, built space stations, placed telescopes in orbit, and unlocked the secrets of the universe with NASA's ...

Perhaps an odd question, but what exactly is the volume of space that makes up various "L" points? Obviously it isn't a precise place in space where only one orbital object sits as if on a gravity ...

The James Webb Space Telescope captured massive galaxy cluster RX J2129. located about 3.2 billion light-years away. A ‘supernova-hosting galaxy’ can be seen three times, at 3 different points in time ...

Jupiter's moon Io stands alone among the solar system's moons. It has more than 400 active volcanoes, and its surface is home to more than 100 massive volcanic mountains, some of which are taller than ...

Trapped in a gravitational push and pull between Jupiter and other Jovian moons, Io is constantly being stretched and compressed. Heat generated by these contortions has melted pockets of the moon's ...

A team of astronomers used the James Webb Space Telescope to create the first 3D atmospheric map of an exoplanet. The fiery WASP-18b, a massive “ultra-hot Jupiter,” revealed striking temperature ...

Star formation begins with protostars in cold molecular clouds, where gravitational contraction precedes nuclear fusion, and their early evolutionary stages are best characterized through ...

Humanity's understanding of the solar system has evolved dramatically following the advent of spaceflight. Over the past seven decades, thousands of sophisticated spacecraft have been launched on ...

Astronomers have yet to find irrefutable proof for any natural satellites of exoplanets—so-called exomoons—but as circumstantial evidence accumulates and the list of candidates grows, the discovery of ...
