Astronomers say they have solved an outstanding problem that challenged our understanding of how the universe evolved—the spatial distribution of faint satellite galaxies orbiting the Milky Way. These satellite galaxies…
Two new studies suggest that certain tetrahedral arrangements of galaxies outnumber their mirror images, potentially reflecting details of the universe’s birth. But confirmation is needed. Physicists believe they have detected…
Why haven't we found wormholes? It might be because they look just like blackholes! A group of researchers at Sofia University has found evidence that suggests the reason that a…
With new algorithms and supercomputers, an incredibly detailed radio map of the universe has been created. Now astronomers can look at radio data of galaxies with much more precision. This…
The South African Radio Astronomy Observatory (SARAO) has released today a new MeerKAT telescope image of the centre of our Galaxy, showing radio emission from the region with unprecedented clarity…
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…
