Lopsided “David and Goliath” Black Hole Merger With an Oddball Origin Story
Researchers suggest a novel process to explain the collision of a large black hole and a much smaller one. A lopsided merger of two black…

The process occurs in active-core nuclei. A molecular gas cloud that accumulates in the central region is blown away by radiation from the black hole’s…
A binary black hole merger likely produced gravitational waves equal to the energy of eight suns. For all its vast emptiness, the universe is humming…
A team of astronomers have identified the first direct evidence that groups of stars can tear apart their planet-forming disc, leaving it warped and with…
The unexpected findings were a result of data collected for more than a decade at the NSF facility, which is managed by the University of…
Astronomers have known for two decades that the expansion of the universe is accelerating, but the physics of this expansion remains a mystery. Now, a…
Cosmologists have zoomed in on the smallest clumps of dark matter in a virtual universe — which could help us to find the real thing…
Scientists Detect First-of-Its-Kind ‘Intermediate-Mass’ Black Hole An international research collaboration including Northwestern University astronomers has witnessed the birth of an “intermediate-mass” black hole. This is…
A new theory published recently in The Astrophysical Journal Letters by scientists from Harvard University suggests that the Sun may once have had a binary…
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state. This census…
Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster,…
New light has been shed on a mysterious and long-standing conundrum at the very heart of our galaxy. The new work offers a potential solution…
A mystery surrounding the space around our solar system is unfolding thanks to evidence of supernovae found in deep-sea sediments. Professor Anton Wallner, a nuclear…
The most massive stars in the universe are born inside cosmic clouds of gas and dust, where they leave behind clues about their lives for…
Solar flares emit sudden, strong bursts of electromagnetic radiation from the Sun’s surface and its atmosphere, and eject plasma and energetic particles into inter-planetary space….
Enstatite chondrite meteorites, once considered ‘dry,’ contain enough water to fill the oceans — and then some. A new study finds that Earth’s water may…
Over one hundred years ago, on May 29, 1919, astronomers observed a total solar eclipse in an ambitious effort to test Albert Einstein’s general theory…
First clear confirmation of accretion disk formation in a tidal disruption event without x-ray emissions supports theoretical predictions. When a star passes too close to…
