Milky Way Galaxy, are made of two populations of stars that are distinct in their physical properties as well as their locations. He applied the termPopulation Ito the stars thatconstitutethe spiral arms of Andromeda and to most of the stars that are visible in the Milky Way system in the ...
Studying the Milky Way used to be notoriously difficult. Astronomers sometimes compare the effort to attempting to describe the size and structure of a forest while being lost in the middle of it. From our position onEarth, we simply lack an overview. But two ground-breaking space telescopes l...
Using a complete sample of about 330,000 dwarf stars, well measured by Gaia DR3, limited to the galactic north and south solid angles |b|<75° and up to a vertical distance of 2 kpc, we analyze the vertical structure of the Milky Way stellar disks, based
The Gaia space telescope, launched in 2013 by the European Space Agency, began observing the universe the following year. Astronomers have used Gaia’s observations to discover previously unknown structures in the Milky Way, helping them piece together the history of the galaxy. ...

Besides our Milky Way galaxy, there are millions and millions of galaxies in the known universe. The Hubble Space Telescope discovered more than 10,000 galaxies by viewing a small part of space continuously for 12 days. What is the Milky Way?
Astronomers used to think that all of the stars in theuniversewere part of the Milky Way, but that changed in the 1920s when Edwin Hubble, the American astronomer after whom the famous telescope is named, managed to calculate the distance of the Andromeda nebula (today known as the Andromeda...
Crucially, this sample includes not only some of the oldest stars that were formed inside the Galaxy but also stars formed externally and subsequently accreted onto the Milky Way. Leveraging this resolution in age, we provide compelling evidence in favour of models in which the Galaxy had already...
The first-ever photo of Sagittarius A*, the supermassive black hole at the center of the Milky Way galaxy, was released May 12 by the Event Horizon Telescope team.
