Scientists have unlocked the 3D structure of molecular clouds in the Milky Way’s center, using a groundbreaking X-ray technique. These cosmic clouds, vital for star formation, were illuminated by past ...

Scientists have created the first-ever 3D maps of star-forming molecular clouds near the Milky Way's supermassive black hole, ...

Hypervelocity stars (HVSs) were first theorized to exist in the late 1980s. In 2005, the first discoveries were confirmed.

In 1920, astronomers Harlow Shapley and Heber Curtis held a Great Debate. Shapley argued that the spiral nebulae were small and in the Milky Way, while Curtis took a more radical position that they ...

In the 1920s, astronomers thought that the Milky Way was the entire universe. Hubble's discovery revealed a much bigger ...

The elliptical galaxy NGC 4660 is one of a hundred galaxies imaged by Hubble that are members of the nearest large galaxy cluster to Earth, the Virgo Cluster. NASA’s James Webb Space Telescope has ...

But only one galaxy stands out as the most important nearby stellar island to our Milky Way -- the magnificent Andromeda galaxy (Messier 31). It can be seen with the naked eye on a very clear ...

Now a study has found something fascinating about our galaxy, the Milky Way. Home to nearly 400 billion ... just as the terrestrial landscape is separated into watersheds." Explaining what BoAs ...

Giant radio galaxies (GRGs) are massive, with plasma jets powered by supermassive black holes at their centers, stretching ...

"It's easy to romanticize Hubble and his discovery of the universe beyond the Milky Way galaxy, but his work really stood on the shoulders of a number of people," said Jeff Rich, an astronomer at ...

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 ...

Observations show Andromeda has a more active star formation history than the Milky Way, potentially due to a past galactic collision. NASA recently released images of the Andromeda galaxy ...
