Black Hole

Globular clusters are extremely dense stellar systems, in which stars are packed closely together. They are also typically very old -- the globular cluster that is the focus of this study, NGC 6397, is almost as old as the Universe itself. It resides 7800 light-years away, making it one of…

According to Einstein’s general theory of relativity, black holes have only three observable properties: mass, spin and charge. Additional properties, or “hair,” do not exist.

On Christmas Eve, Steven Brandenburg, a Milwaukee-area pharmacist, attempted to destroy more than 500 doses of coronavirus vaccine, because, he admitted, he feared the Moderna drug would “alter the recipient’s DNA.” Described in law-enforcement documents as a “conspiracy theorist,” Brandenburg, 46, had reportedly warned his wife that “the world is…

Here, a visualization of that orbiting gas. (Image: © ESO/Gravity Consortium/L. Calçada) The supermassive black hole hiding in the center of our galaxy is…

Almost every galaxy has a supermassive black hole at its heart, with masses of millions to billions of times of the Sun. Since the mass of a central black hole, for the most part, follows the mass of the galaxy itself, astronomers expect the galaxy in the center of Abell…

In a recently shared image by NASA, a galaxy appearing called NGC 6240 contains two supermassive black holes in the process of merging. The image consists of new X-ray data from Chandra (shown in red, orange, and yellow) that has been combined with an optical image from the Hubble Space…

The massive O4.5 V + O5.5 V binary VFTS 352 in the Tarantula Nebula (location indicated by the red cross) is one of the shortest-period and most massive overcontact binaries known. Recent theoretical studies indicate that some of these systems could ultimately lead to the formation of gravitational waves via…

China's Aperture Spherical Radio Telescope (FAST) is the largest and last remaining giant, single-dish telescope after Arecibo's collapse. As China's moon mission advances, experts say the via its resolution and sensitivity, the FAST telescope will help produce critical research over the next decades. Opened in 2016, in November, Chinese state…
