For one, scientists observe a "cosmic fossil" called the cosmic microwave background (CMB). The first light that was free to ...

The Milky Way may be missing a strange X-ray glow long associated with dark matter in other galaxies, a new study has found. If this glowing halo is really missing — and physicists not involved ...

The long-proposed Milky Way and Andromeda galactic merger might not be as certain as astronomers previously believed. ... J. DePasquale and E. Wheatley (STScI), and Z. Levay (background image) ...

Hydrogen near the nucleus of the Milky Way galaxy is hard to observe, but by refining their dish-shaped radio telescope at Kootwijk, the Dutch astronomers picked up its radiation.

Scientists have made the first image of the Milky Way using neutrinos. The extremely low-mass subatomic particles have no electric charge, and pass easily through gas, dust and even stars on their ...

We now have strong evidence that the Milky Way is a source of high-energy neutrinos. ... The result: an excess of 79 neutrinos over the background, with a statistical significance of 4.2 sigma.

The Milky Way is readily visible without the use of a telescope or high-powered binoculars. But if you have them, magnification devices will let you get a closer look at various points of interest.

We are not alone—at least as a galaxy. About 50 dwarf galaxies surround the Milky Way.But when its intense gravity inevitably draws them to venture too close, they will probably be annihilated.

The Milky Way galaxy has a graveyard of dead stars that stretches three times the height of the galaxy, according to new research. Astronomers found the ancient stellar remnants when they mapped ...
