A new study has revealed that satellite galaxies may have vanished from the Milky Way.
The Milky Way began to form relatively soon after the Big Bang explosion that marked the beginning of the universe some 13.8 billion years ago.
The sun, located roughly 26,000 light-years from the supermassive black hole residing at the center of the galaxy, formed about 4.5 billion years ago.
Astronomers have mapped the history of one of the nearest galaxies, the Large Magellanic Cloud, in more detail than ever before, showing when its stars formed

Some supermassive black holes blast out powerful winds that astrophysicists suspected could kill small neighbouring galaxies – but it turns out they actually clear a spot for those small galaxies to settle into
