On a clear night, the Milky Way and the Andromeda galaxy look like close neighbors. In space, they really are.

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 ...

A series of high-resolution simulations has revealed a striking new perspective on theMilky Way’s position in the cosmos. Far ...

In the close Universe, the distance typically is a predictor of speed: more distant galaxies recede more rapidly. Another ...

There is a lot we have yet to understand about the center of the Milky Way—could it be due to a mass of invisible dark matter?

Cosserat Microrotation. Neutrinos are “twists” that don’t stretch the lattice. Their mass is suppressed by the vacuum’s twist impedance (approx 0.05 eV). A natural, mechanical explanation for why ...

The young galaxy cluster existed about 12.8 billion years ago and has an estimated mass 20 trillion times that of the sun ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

Dating to only a billion years after the big bang, JADES-ID1 may be the earliest, most distant galaxy protocluster astronomers have ever seen ...

Oh, sure, I can “code.” That is, I can flail my way through a block of (relatively simple) pseudocode and follow the flow. I ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic ...
