Astronomers have taken a look at our closest galactic neighbors, the dwarf spheroidal galaxies, and have found that they're devoid of star-forming gas--and our Milky Way may be to blame.
Scientists have long wondered whether matter is falling into the massive black hole in the center of our Milky Way galaxy, or being ejected from it. Now, scientists are searching for an answer.
Why are there so many disc galaxies like our Milky Way in the universe? Astronomers may have found the reason, thanks to ALMA.
Scientists have made new strides when it comes to cataloguing the stars in our Milky Way galaxy. They've found that no fewer than 219 million stars are located in our home galaxy, revealing a bit more about the features of the Milky Way.
Our Milky Way galaxy isn't alone. Astronomers have found that it's part of a newly identified and huge supercluster of galaxies, which have been dubbed "Laniakea," which means "immense heaven" in Hawaiian.
Astronomers have created some astonishing new maps of the dusty material between the stars of our Milky Way galaxy. The findings may just bring researchers one step closer to cracking a stardust puzzle that has stumped scientists for nearly a century.
Scientists have taken a closer look at our galaxy and our neighbor, Andromeda, and have found that the Milky Way may actually be less massive than expected.
Astronomers are learning more about the Milky Way than ever before. They've created a detailed, 3D map of the dusty structure as seen from Earth's northern hemisphere. The new map could help astronomers in future studies of this region of space.
Touring the Milky Way now is as easy as clicking a button with NASA's new zoomable, 360-degree mosaic presented Thursday at the TEDActive 2014 Conference in Vancouver, Canada.
We live in a galaxy known as the Milky Way -- a vast conglomeration of 300 billion stars, planets whizzing around them, and clouds of gas and dust floating in between.
Astronomers have found evidence backing up theoretically predicted divisions in the chemical composition of the stars that make up the Milky Way's disc, which suggests that stars in the inner regions of the Galactic dis were the first to form. This means that our galaxy grew from the inside-out.
Astronomers have debated exactly how many arms our Milky Way Galaxy has. While some were certain that our galaxy had four spiral arms, images taken by NASA's Spitzer Space Telescope showed only two arms. Now, scientists have reaffirmed that our galaxy has four spiral arms, paving the way to future s...
