Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are leading a new effort to land a radio telescope on the moon. If successful, the project will mark the first step towards exploring the ...
Observations of supermassive black holes at the centers of galaxies point to a likely source of dark energy—the 'missing' 70% of the universe.
Sometimes to know what the matter is, you have to find it first.
What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.
Is the Milky Way special, or, at least, is it in a special place in the universe? An international team of astronomers has found that the answer to that question is yes, in a way not previously appreciated. A new study shows ...
Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos ...
A group of MPIA astronomers has managed to identify the "poor old heart of the Milky Way"—a population of stars left over from the earliest history of our home galaxy, which resides in our galaxy's core regions.
Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved—the spatial distribution of faint satellite galaxies orbiting the Milky Way.
The European Space Agency (ESA) recently announced a new mission of its science program: a small telescope orbiting the Earth dubbed Arrakhis. But although its name is inspired by the sci-fi novel Dune, it will not be looking ...
In 1916, Einstein finished his theory of general relativity, which describes how gravitational forces alter the curvature of spacetime. Among other things, this theory predicted that the universe is expanding, which was confirmed ...
