Astronomers believe they have spotted an elusive intermediate-mass black hole shredding a distant star, and they have ...

A bizarre planet defies cosmic norms: scientists have confirmed a giant planet orbiting in reverse around one star in a close ...

They have a few potential hypotheses to explain why J0524-0336 is so unusual. One possibility is that the star may be in a stage of stellar evolution that has never been observed before ...

Astro­physics: Star-child­hood shapes stel­lar evo­lu­tion Date: September 19, 2022 Source: University of Innsbruck Summary: In classical models of stellar evolution, so far little importance ...

The Hubble Space Telescope searches the universe to understand how planets, stars, and galaxies form. Recently, it captured this image of a nebula known as GN 04.32.8 within a larger stellar ...
