How Loop Quantum Gravity Could Match Anomalies in the CMB with Large Structures in the Modern Universe
A strange celestial tension could be caused by a cosmic tango between events at very small and very large scales.
Gamma-Ray Telescopes Can Measure the Diameters of Other Stars
Four gamma ray telescopes have used a new method of interferometry to measure the size of two stars.
A Black Hole Popping Out of a Traversable Wormhole Should Give Off a Very Specific Signal in Gravitational Waves
Gravitational wave astronomy has changed the way we view the cosmos. In only a few years we have observed the collisions of black holes and neutron stars, confirming our theoretical understanding of these strange objects. But as gravitational wave astronomy matures, it will allow us to probe the very nature of space and time itself. …
What Shuts Down a Galaxy’s Star Formation?
A new study finds that while black holes drive the formation of galaxies, they are also what kills them in the end.
Stars Like Our Sun Become Lithium Factories as They Die
In the beginning, the big bang created three elements: hydrogen, helium, and lithium. But it only produced a trace of lithium. For every lithium atom created, the big bang produced about 10 billion hydrogen atoms, and 3 billion helium atoms. The ratio of primordial elements is one of the triumphs of the big bang model. …

Earth’s Magnetic Field is Changing Surprisingly Quickly
The Earth’s magnetic North pole has been moving awfully fast in recent years. But there’s nothing to worry about.
Astronomers Might Have Seen a Star Just Disappear. Turning Straight to a Black Hole Without a Supernova
A brilliant blue star has disappeared from view, which could mean it became a black hole in a novel way.
Astronomers Just Detected Either the Least Massive Black Hole, or a Strange and Massive Neutron Star
Somewhere around 2.5 solar masses is the line between black holes and neutron stars. Now we’ve found an object right on the edge.
A Repeating Fast Radio Burst Has Been Found. It Flares for 4 Days and then Remains Silent for 12 Days
Five hundred million light-years from Earth, there is a deeply unusual object. It is radio silent for 12 days, then erupts in bright radio bursts. We still aren’t sure what the object is.
Japanese Dark Matter Detector is Seeing a “Surprising Excess of Events”
A search for dark matter has found an extra signal in their data that could point toward proof of dark matter.
