While the presence of these molecules is not proof of ancient life on Mars, scientists say it shows we could detect chemical signatures of past life, if it ever existed.
The observation of titanic jets emerging from the supermassive black hole at the heart of a distant galaxy could be a grim prediction of the Milky Way's future.
Using data from the Euclid Space Telescope, astronomers have discovered a stunning 2,674 dwarf galaxies, the study of which could help better understand cosmic evolution.
A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.
JWST could potentially detect the signature of methyl halide compounds, produced by microbial life in Earth's ocean, on hypothetical hycean exoplanets.
Astronomers have examined infant planets orbiting a star 370 light-years away, seeing the exomoon forming disks of gas and dust around them in unprecedented detail.
A new model that incorporates data gathered by the JWST could help scientists understand the composition and mass of objects in the distant Kuiper Belt and beyond.
NASA's Lucy spacecraft will soon travel by asteroid Donaldjohanson, which formed roughly 150 million years ago.
The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once thought.
The Mars water debate continues. A team of scientists suggests vast oceans of water may not be locked within the Red Planet's crust, despite InSight lander data.
