A mysterious phenomenon at the center of our galaxy could be the result of a different type of dark matter.
Astronomers have discovered strong evidence for the closest supermassive black hole outside of the Milky Way galaxy. This giant black hole is located in the Large Magellanic Cloud, one of the nearest galactic neighbors to ...
Radio astronomers see what the naked eye can't. As we study the sky with telescopes that record radio signals rather than light, we end up seeing a lot of circles.
Astronomers have performed a multiwavelength study of nine open cluster candidates. As a result, they found that all of them are genuine open clusters and characterized by their fundamental properties. The finding was reported ...
Located 2.5 million light-years away, the majestic Andromeda galaxy appears to the naked eye as a faint, spindle-shaped object roughly the angular size of the full moon. What backyard observers don't see is a swarm of nearly ...

Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), and her team have pioneered the use of gravitational acceleration measurements of binary ...
Have you ever wondered how astronomers manage to map out the Milky Way when it's so incredibly vast? One of the most powerful tools is something called 21 cm radiation.
Stars form in regions of space known as stellar nurseries, where high concentrations of gas and dust coalesce to form a baby star. Also called molecular clouds, these regions of space can be massive, spanning hundreds of ...
The space telescope Gaia has created the largest three-dimensional map of the Milky Way ever. On January 15, 2025, Gaia shut down after 11 years in space. But the research on data Gaia collected will continue for many years ...
