Gaia space telescope aimed to create an accurate and detailed 3D map of billions ... of stars in the Milky Way since its launch in December 2013 to create a ‘huge stellar census’.

One of the most extensively studied stellar ... density of stars along the stream, while a spur is an over-density of stars stretching out from the main body of the stream. The Milky Way's ...

About 6 million light-years from Earth, it is one of the Milky Way's closer neighbors ... form a so-called stellar halo: a sprawling, low-density cloud of stars that surrounds the bright central ...

while a spur is an over-density of stars extending outward from the main body of the stream. Since dark matter governs the motion of stellar streams, astronomers can use them to trace invisible dark ...

We can trace the "spin-up" of the Milky Way disk in the way the average properties of stellar orbits change as ... the dust in the Milky Way's disk to map many more stars and make a direct ...

For decades, scientists have marveled at the Local Hot Bubble—a vast, low-density region stretching roughly 1,000 light-years ...

we need to study one with a stellar system associated with it. Palomar 5 is the only case, making it a Rosetta Stone for understanding stream formation and that is why we studied it in detail." Map of ...
