As you might know, the Milky Way Galaxy, in which we are all floating, has a black hole with a mass 4.5 million times bigger than that of our sun at its very center. So, when NASA says a documented occurrence in that vast pit of darkness “raises questions about the behavior of this giant black hole and its surrounding environment,” I get a little nervous.
The Milky Way, the galaxy we live in, is part of a cluster of more than 50 others that make up the ‘Local Group’, a collection that includes the famous Andromeda Galaxy and many other far smaller objects. Now a Russian-American team have added to the canon, finding a tiny and isolated dwarf galaxy almost 7 million light-years away.
Using a century-old technique to probe the borders of our galaxy, a team of Australian astronomers has estimated the amount of dark matter in the Milky Way. Intriguingly, according to their new calculations, there could be half as much of this poorly understood substance in our galaxy as once thought.
We’ve got about 4 billion years before the Milky Way galaxy is no more. We’re on a collision course with our nearest neighbor, Andromeda, and now—thanks to researchers with the International Centre for Radio Astronomy Research—we have an updated idea what that galatic crash might look like.
A team of astronomers led by John Bochanski has found the farthest stars in our galaxy in the mysterious Milky Way halo, a rare discovery that may change our understanding of the formation of our galactic home.
Everybody has a different definition for the word “home.” For some, it’s the house they live in. For those with a more UNESCO-themed mindset, home is the planet Earth, our globally shared clump of rock hurtling through the dark reaches of space.
Scientists are about to observe a supermassive black hole‘s table manners. While studying the motions of stars near the supermassive black hole at the center of the Milky Way, astronomers discovered a huge gas cloud, called G2, heading directly toward it. The findings appeared in the January 5 issue of Nature.
“We have direct images of what the Milky Way looked like in the past”, said Pieter G. van Dokkum researcher at Yale University, after he and his team of specialists have used images taken by Hubble Telescope in order to present us a “view” of our earlier-galaxy.
