By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the galaxy's mass-weighted chemical abundances and age structure. This ...

Jan. 11, 2024 — A team of astronomers has created the first-ever map of magnetic field structures within a spiral arm of our Milky Way galaxy. Previous studies on galactic magnetic fields only ...

In their study published Thursday in the journal Science, they showed that by measuring the distance between classical Cepheid variable stars within the galaxy, they could develop a three-dimensional ...

Using data from the APOGEE survey, astronomers from the Leibniz Institute for Astrophysics Potsdam, the University of Vienna and Paris Observatory have reconstructed the properties of ‘hidden’ stars ...

For the first time, NASA’s James Webb Space Telescope has detected and “weighed” a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way ...

Astronomers have observed a binary star system orbiting near the supermassive black hole at the center of the Milky Way galaxy. The discovery of Sagittarius A* (Sgr A*), published Tuesday in ...

Scientists have found the beginnings of a young universe that may offer insights into the beginnings of our own Milky Way Galaxy. Geoff Bennett and Miles O'Brien discussed why scientists are ...

"We knew to expect it based on current physics, but it's surprising that we actually saw it." Mowla, who spotted the galaxy in ... the fully formed Milky Way is about 100,000 light-years across ...

This image released by the Event Horizon Telescope Collaboration, May 12, 2022, shows a black hole at the center of our Milky Way galaxy. The Milky Way black hole is called Sagittarius A* ...

At this stage, the galaxy was about 10,000 times less massive than our current Milky Way, which is typical of galaxies at that epoch," Mowla added. So how did the firefly name come about?
