HVS1, which may be an old metal-poor hypervelocity star of galactic center origin. The finding, based on the data from the ...

The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it’s also cloaked in so much dust that most stars within are rendered invisible. Harvard ...

An obvious conclusion is that they're all related and that SMBHs like Sgr A* in the Milky Way become so massive through a long sequence of mergers. When trying to piece together the Milky Way's SMBH ...

New research led by Dr. James De Buizer at the SETI Institute and Dr. Wanggi Lim at IPAC at Caltech revealed surprising results about the rate at which high-mass stars form in the galactic center of ...

Earth—our tiny blue dot in the galaxy—is approximately 26,000 light years away from a fascinating and active region of the Milky Way called the Central Molecular Zone (CMZ). This region holds clues ...

For over a decade, a dim but persistent glow near the center of the Milky Way has confused astronomers. This mysterious emission, known as the Galactic Center Excess, glows in high-energy gamma rays ...

The center of our galaxy is a frenzy of activity. A behemoth black hole — 4 million times as massive as the Sun — blasts out energy as it chows down on interstellar detritus while neighboring stars ...

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It’s so well understood that ...

A detailed infrared view of the Galactic Center region of our Milky Way Galaxy. These infrared images are sensitive to the presently forming massive stars there as well as the emission from cool ...
