Caltech researchers use deep learning and supercomputing to identify Nyx, a product of a long-ago galaxy merger. Astronomers can go their whole career without finding…
Scientific ‘Red Flag’ Reveals New Clues About Our Galaxy Figuring out how much energy permeates the center of the Milky Way — a discovery reported…
One of the biggest and longest-standing questions in the history of human thought is whether there are other intelligent life forms within our Universe. Obtaining…
The area around the supermassive black hole at the center of our Milky Way galaxy is dominated by gravity, but it’s not the only force…
‘Groupie’ galaxies orbiting Milky Way tell us about dark matter, how galaxy formed. We live in a big-city galaxy. The Milky Way is so big…
Launched in 2013, the Gaia satellite has been scanning the sky to measure the positions, distances and motions of more than one billion stars in…
The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found quasi-periodic flickers in millimeter-waves from the center of the Milky Way, Sagittarius (Sgr) A*. The team…
Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on…
Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA’s star-mapping satellite Gaia suggest the distortion might be caused…
An abundance of mysterious gamma radiation exists in the center of the Milky Way, called the Galactic Center GeV Excess. Previous research determined that this…
Is there dark matter at the center of the Milky Way? A new analysis puts dark matter back in the game as a possible source…
Star-quake vibrations lead to new estimate for Milky Way age. Data gathered by NASA’s now defunct Kepler telescope provides a solution to an astronomical mystery….
A radio telescope in the Western Australian outback has captured a spectacular new view of the center of the galaxy in which we live, the…
International team detected radio bubbles with South Africa’s MeerKAT telescope. A gigantic, balloon-like structure has been hiding in plain sight, right in the center of…
Our Milky Way is a frugal galaxy. Supernovas and violent stellar winds blow gas out of the galactic disk, but that gas falls back onto…
Researchers find evidence of a cataclysmic flare that punched so far out of the galaxy its impact was felt 200,000 light years away. A titanic,…
This infrared image from NASA’s Spitzer Space Telescope shows a cloud of gas and dust full of bubbles, which are inflated by wind and radiation…
