The antimatter counterpart of a light atomic nucleus can travel a long distance in the Milky Way without being absorbed, shows the international ALICE collaboration in an article published today in Na...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The results are...

Astronomers using the National Science Foundation’s Very Long Baseline Array (VLBA) have directly measured the distance to a star-forming region on the opposite side of our Milky Way Galaxy from the S...
In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that, contrary to previously standard lore, up to half of the matter in our Milky Way galaxy may come from dist...

For decades, astronomers have found distant galaxies by detecting the characteristic way their gas absorbs light from a bright quasar in the background. But efforts to observe the light emitted by the...
New delta Scuti:Rare pulsating star 7,000 light years away is 1 of only 7 in Milky Way
New delta Scuti pulsating star 7,000 light years 1 of only 7 Milky Way
