Scientists in Australia and China create 3D map revealing the true shape of the galaxy
ESA’s Gaia mission has made a major breakthrough in unravelling the formation history of the Milky Way.
Astronomers analyzing data from the second release of ESA’s star mapping mission Gaia have shown that our Milky Way Galaxy is still enduring the effects of a near collision that set millions of its stars moving like ripples on a pond. The close encounter likely took place sometime in the past 300-900 million years, and the culprit could be the Sagittarius dwarf galaxy, an elliptical loop-shaped galaxy located 78,300 light-years away. It was discovered because of the pattern of movement it has given to stars in the Milky Way disk.
All of this adds a new layer to the search for life on other planets: apart from finding planets in the “Goldilocks” area, where they are neither too far nor too close to their star….
A swarm of thousands of black holes may surround the giant black hole at the heart of our galaxy, a new study finds.
For decades, astronomers have puzzled over the exact source of a peculiar type of faint microwave light emanating from a number of regions across the Milky Way.
