Discover why astronomy and cosmology are the universe's mapmakers. Discover how scientists trace galaxies, the cosmic web, and the large-scale architecture of our entire existence in three dimensions ...

A vast, flat sheet of dark matter may solve the long-standing mystery of why our neighboring galaxy Andromeda is speeding ...

A flat plane of dark matter beyond the Local Group may explain why nearby galaxies move away from us instead of falling ...

The Millennium Simulation Project is a series of computer simulations run since 2005 to understand how galaxies and galaxy clusters form and come together to create large-scale filamentary structures.

The solution to a persistent astronomical question that has puzzled scientists for half a century has emerged not from direct observation, but from the computing power of sophisticated computer ...

The universe is so vast, and the difficulty of discovering all that there is out in the cosmos is so great, that one might as well count all the grains of sand in the Sahara. But now, with the help of ...

In A Nutshell A star 3,260 light-years away dimmed by over 95% for six months, one of the longest stellar blackouts ever ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

A flat earther attempted to expose NASA using what he claimed was proof. The problem is the image he relied on was fake. In this video, we break down what went wrong, how the image was misused, and ...

The early Universe refers to the onset and first couple of billion years of the Universe. Research topics include but are not limited to the radiation leftover from the Big Bang (cosmic microwave ...

A newly released deep-space portrait captures a spiral galaxy whose outer arm appears to curl protectively around a smaller companion, a scene that looks almost choreographed yet is driven by gravity ...

The path of 14C from cosmic rays to cellulose. Green arrows denote newer pools of 14C and brown arrows denote older pools. The size of the arrow reflects best estimates of size of the carbon pool.
