Searching for exomoons—moons that orbit around another planet—was one of the most exciting capabilities expected of the James ...

Coiled and snakelike, a set of four identical shells surrounds a violent stellar dance 8,000 light-years from Earth.

A supernova remnant, Cassiopeia A (Cas A), resulting from a stellar explosion approximately 11,000 years ago, is being studied using the James Webb Space Telescope (JWST). JWST observations focus on a ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...

The range of possible locations – represented by yellow points – of 2024 YR4 on Dec. 22, 2032. The range decreased from April to June as we gained more data and improved our certainty of the ...

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 ...

An international team including astronomers from the University of Geneva (UNIGE) and the National Center of Competence in ...

A new study of the red dwarf system TOI-3884 has uncovered rare, persistent spot-crossing signals that reveal unusually detailed information about the star’s magnetic activity and the planet’s orbital ...

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 ...
