Our galaxy is not alone. Swirling around the Milky Way are several smaller, dwarf galaxies — the biggest of which are the Small and Large Magellanic Clouds, visible in the…
Very cool research on the detection of an intermediate-mass (approx. 100,000 times the mass of the Sun) black hole in the most massive Globular Cluster of Andromeda. This means that…
Scientists say 35 novel discoveries included a pair of massive black holes 145 times as heavy as the sun orbiting each other. Astronomers have detected a record number of gravitational…
An updated search for primordial gravitational waves has not found a signal, which implies that some popular early Universe models are becoming less viable. Remarkably, the large-scale Universe can be…
The Event Horizon Telescope is expanding its portfolio of black hole images. In 2019, the telescope unveiled the first image of a black hole, revealing the supermassive beast 55 light-years from…
Experiment opens up field for new physics, say Fermilab, UChicago scientistsThe news that muons have a little extra wiggle in their step sent word buzzing around the world this spring.…
There are certain rules that even the most extreme objects in the universe must obey. A central law for black holes predicts that the area of their event horizons —…
The Milky Way’s Double Bubble When it comes to blowing bubbles, never go toe-to-toe with a galaxy. Ten years ago, astronomers were astonished to discover large bubble-like structures emerging from the heart…
The Search for Dark Matter Is Dramatically Expanding The Search for Dark Matter Is Dramatically Expanding Physicists are checking whether dark matter tickles different types of detectors, nudges starlight, warms…
For as long as there has been a Universe, space has been expanding. It winked into existence roughly 13.8 billion years ago, and has been puffing up ever since, like…
CfA Scientists Discover Mysterious Spiral Structures around a "Planet Factory" Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) announced today the discovery of a complex…
“Stellar archaeology” reveals remnant of ancient globular cluster that’s “the last of its kind” A team of astronomers including Carnegie’s Ting Li and Alexander Ji discovered a stellar…
A Vast Stream of Flowing Stars Is Evidence of The Milky Way's Violent History Using data from the Gaia Milky Way mapping survey, astronomers have discovered a vast…
Scientists spot flash of light from colliding black holes. But how? Scientists think they identified two black holes merging that produced a burst of light. Black holes aren't supposed…
