Stars don't form out of nothing, but tracking the gas and dust that do eventually form stars is hard. They float around the galaxy at almost absolute zero, emitting essentially no light, and generally ...

Simulating a billion years using previous best-resolution simulations would take almost 36 years of real computing time.

Research on heliospheric physics and interstellar medium dynamics has advanced our understanding of the complex interaction between the solar wind and the interstellar environment. The heliosphere – a ...

Harvard astrophysicist Avi Loeb accuses NASA of releasing 'deceptive' images of interstellar object 3I/ATLAS, intensifying debate over whether the fast-approaching visitor is a natural comet or ...

Molecules containing noble gases shouldn’t exist. By definition, these chemical elements — helium, neon, argon, krypton, xenon and radon — are the party poopers of the periodic table, huddling in the ...
