It’s 30 years ago to the day that the Hubble telescope was launched – and to celebrate its birthday, the veteran observatory has produced another astonishing image of the cosmos.
Just as the sun has planets and the planets have moons, our galaxy has satellite galaxies, and some of those might have smaller satellite galaxies of their own. To wit, the Large Magellanic Cloud (LMC), a relatively large satellite galaxy visible from the Southern Hemisphere, is thought to have brought at least six of its own satellite galaxies with it when it first approached the Milky Way, based on recent measurements from the European Space Agency’s Gaia mission.
Our galaxy spans 1.9 million light-years, a new study finds
There’s something really weird in the centre of the Milky Way.
An enormous wave has been discovered in the Milky Way that may have formed as a result of a collision with a massive mystery object—potentially a clump of dark matter—scientists have said.
The object is locked in orbit with a star about 13,800 light-years away from Earth
Astronomers say S5-HVs1 ventured close to supermassive black hole before being ejected
The behemoth at the center of the galaxy flared up in near-infrared wavelengths
Scientists say Milky Way’s Sagittarius A* has been more active in recent months
A mysterious black hole—that has yet to be discovered—in one of our galaxy’s spiral arms appears to have hurled a star across the Milky Way, an international team of astronomers has said.
