Researchers from the University of Miami believe...
Scientists reveal hidden radio signals from the edges of extreme stars
Pulsars are some of the strangest objects in the universe.
They are the dense, rapidly spinning remains of dead stars, and they send out beams...
New study suggests atoms can “hear” ripples in spacetime
Gravitational waves are tiny ripples in space and time, created by some of the most violent events in the universe, such as when two...
Why the Small Magellanic Cloud is behaving so strangely
Astronomers have discovered that one of our closest neighboring galaxies is going through a dramatic transformation—and they can watch it happening in real time.
The...
Giant craters may reveal if Psyche is a lost planetary core

Two supermassive black holes on the verge of a merger
In March 2021, astronomers observed a high-energy burst of light from a distant galaxy. Assigned the name AT 2021hdr, it was thought to be...
Exploring the impact of the strong force on gravitational wave signals
In the silent vastness of space, there's an invisible symphony of waves constantly moving around us. These aren't ordinary waves; they're gravitational waves, ripples...
Mars isn’t dead. Its volcanoes could still be active
Most volcanism on the Red Planet occurred between 3 and 4 billion years ago, with smaller eruptions in isolated locations continuing perhaps as recently...
Black holes are surprising builders of the universe
