If you ever wanted to see what the Milky Way looks like in terms of the giant black hole in the center of it? Well now you can.
Now this is some serious hunger.
Ten billion years ago, our own Milky Way galaxy "cannibalized" a smaller nearby galaxy, according to a new study published Monday. millions of years did not calm down, say the authors of the study.
"This is a very gradual process – it's not like a catastrophe," said lead author Carme Galart of the University of La Laguna, Spain. "This is very massive, so it happens slowly in the human sense (but) not so slow in cosmic time."
The painter's impression of the Milky Way, including the spiral arms. It has been updated to include the latest mapping of the central protrusion shape derived from the ESO telescope VISTA data from the study. The smaller dwarf galaxy, the one that is "eaten", is called Gaia-Enceladus. It slowly formed the halo of our Milky Way. According to Newsweek, this is not the only time the Milky Way has merged with other galaxies. It is believed that throughout her story she has consumed many other, smaller galaxies. And in a few billion years, it will merge with our great neighboring galaxy, Andromeda.
The study also gives an accurate date of the age of the Milky Way stars. Knowing the exact ages of the stars gives information on which the stars were present in the Milky Way before the merger and those that originate from Gaia-Enceladus. because they give us a sort of window in the past of our galaxy, "said Chris Hayes, of the University of Virginia who did not participate in the study, and said that these earliest star populations must exist, but now that they
The Milky Way includes about 100 billion stars, reported by NASA, including our sun, the sun formed "only" 4.5 billion years ago, much later than this cosmic collision between galaxies.
The study was published in the reviewed British journal Nature Astronomy.
