Moon’s orbit could be a natural gravitational wave detector
Gravitational waves, predicted by Albert Einstein at the start of the 20th century and detected for the first time in 2015, are the new...
The Sun is slowly tearing this comet apart
Using ground-based and space-based observations, a team of researchers has been monitoring a difficult-to-see comet carefully.
It’s called Comet 323P/SOHO, and it was discovered over...
Neutron stars could be the best way to measure dark energy
Dark energy is central to our modern theory of cosmology.
We know the universe is expanding at an ever-increasing rate, and the clearest explanation is...
This comet emits ancient molecular oxygen from its nucleus
Comet 67P/Churyomov-Gerasimenko – arguably the most-studied comet in history – has yielded a cosmic surprise:
It emits molecular oxygen drawn from its nucleus.
Comet comas –...
Scientists reveal the massive bubbles at center of Milky Way galaxy
In 2020, the X-ray telescope eRosita took images of two enormous bubbles extending far above and below the center of our galaxy.
Since then, astronomers...
Scientists recreate the harsh conditions inside gigantic galaxy clusters
Galaxies rarely live alone.
Instead, dozens to thousands are drawn together by gravity, forming vast clusters that are the largest objects in the universe.
“Galaxy clusters...
The best way to leave the solar system might be to fly uncomfortably close...
We’ve reported before on the conceptual mission known as the Interstellar Probe.
This ambitious mission would visit the interstellar medium about 1,000 AU away from...
This neutron star blows out strong winds while eating companion star
Astronomers have found for the first time blasts of hot, warm, and cold winds from a neutron star whilst it consumes matter from a...
Rapid spin delays the collapse of merged neutron stars into black hole
When two neutron stars spiral into one another and merge to form a black hole — an event recorded in 2017 by gravitational wave...
Scientists find rare black hole in our neighboring galaxy
Astronomers discovered a black hole unlike any other.
At one hundred thousand solar masses, it is smaller than the black holes we have found at...
