SPACEBecause it dwells in the galactic plane, where it may easily be covered by the Milky Way's 400 billion stars, the stellar stream has stayed hidden from astronomers for a long time.
For several years, the scientific consensus is that the dark mass in the middle of the Milky Way, designated Sagittarius A*, is a black hole - and a new study is challenging the widely-accepted notion.
Dark Matters are just one of the few cosmic questions we still face up to this day. Experts believe that the revelation to the dark matter particles might mean more than we expect.
Astronomers released a new all-sky map of the outermost regions of the Milky Way to show information on small galaxies that traveled through its galactic halo.
Vast halo of dark matter around Tucana II is said to be five times larger than previously estimated. The dwarf galaxy is 163,000 light years from Earth.
Rogue planets are free-floating, non-star circling planets. Scientists have found the smallest rogue object in our Milky Way galaxy. They are about the size of Mars and Earth.
Scientists answered how the Magellanic Stream from two small galaxies that entered the Milky Way could have gained mass that is a billion times more massive than the sun.
After pouring through data from the Atacama Large Millimeter/ submillimeter Array (ALMA), a team of astronomers has found a distant galaxy similar to our own Milky Way.
A study from the University of Warwick revealed that a blast sends a star out of its orbit with another star in a partial supernova and is now traveling across the Milky Way galaxy.
A recent discovery of 100 million billion stars hidden the Milky Way is named the South Pole Wall. Cosmographers explain how it's possible to map out what they can't see in space.
Scientists made a new discovery regarding the behavior of gases at the Milky Way's core, the Tilted Disk. Discovering the source of their activity may explain the Galaxy's energy.
Astronomers create the first X-Ray map of the Milky Way with more than one million cosmic objects. The team is already working on future surveys in the next few years.
Astrophysicists calculated how many life forms may exist within our Milky Way, yet it's impossible to communicate with them with our current technology. Is it possible that life on Earth occurred in the same way as these planets?
