Medicine & TechnologyAstronomers 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.
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.
