New Evidence of the Existence of an Elusive Type of Black Hole
Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of…
Gemini Reveals Outflowing Gas from Supermassive Black Hole Nuclei
Supermassive black holes at the nuclei of most galaxies, including our Milky Way, develop gradually as material accretes onto the seed black hole. The physical…
Chandra Views Black Hole Bounty in the Center of the Milky Way
Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory….
What It Looks Like When A Massive Black Hole Devours A Star
Dr. Jane Lixin Dai, theoretical astrophysicist and assistant professor and Prof. Enrico Ramirez-Ruiz, both from the DARK Cosmology Center at the Niels Bohr Institute, University…
ExaHyPE – Simulation Code for New Generation of Supercomputers
Even after the direct measurement of their gravitational waves, there are still mysteries surrounding black holes. What happens when two black holes merge, or when…
Chandra Reveals X-Ray Binary Stars at the Galactic Center
The center of our Milky Way galaxy is about twenty-five thousand light years from Earth, in the direction of the constellation Sagittarius. At the core…
Webb Space Telescope Will Capture Light From First Generation Stars
The first stars in the universe blazed to life about 200 to 400 million years after the big bang. Observing those very first individual stars…
Milky Way’s Supermassive Black Hole May Have ‘Wandering’ Siblings
Astronomers are beginning to understand what happens when black holes get the urge to roam the Milky Way. Typically, a supermassive black hole (SMBH) exists…
Is Dark Matter Composed of Primordial Black Holes?
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of…
Unprecedented ‘Dissection’ of Twin Galaxies in Final Stages of Merging
Researchers at the University of Colorado Boulder have completed an unprecedented “dissection” of twin galaxies in the final stages of merging. The new study, led…
Astrophysicists Test Theories of Gravity with Black Hole Shadows
Can we tell black holes apart? Astrophysicists at Goethe University Frankfurt answer this question by computing images of feeding non-Einsteinian black holes: At present it…
Dense Stellar Clusters Are Home to Black Hole ‘Megamergers’
Black holes in dense stellar clusters could combine repeatedly to form objects bigger than anything a single star could produce. When LIGO’s twin detectors first…
Astrophysicists Discover a Dozen Black Holes Orbiting Sgr A*
A Columbia University-led team of astrophysicists has discovered a dozen black holes gathered around Sagittarius A* (Sgr A*), the supermassive black hole in the center…
Astronomers View Black Hole Jets Deep Inside Perseus A
An international team of researchers has imaged newly forming jets of plasma from a massive black hole with unprecedented accuracy. Radio images made with a…
Astronomers Dedicate the Birth of a New Black Hole to Stephen Hawking
One of the MASTER Global Robotic Net telescopes (MSU) located on Tenerife (Spain, Canary Islands) helped the scientists observe the gamma-ray burst caused by the…
Radio Echoes of a Black Hole Feeding on a Star Detected
Signals suggest a black hole emits a jet of energy proportional to the stellar material it gobbles up. On Nov. 11, 2014, a global network…
Outbursts From Supermassive Black Hole Transform Exoplanets
A team of astrophysicists and planetary scientists has predicted that Neptune-like planets located near the center of the Milky Way galaxy have been transformed into…
