Finding the Universe’s first black holes with the help of Hawking radiation.
Could black holes be dark energy?
Astronomers looking at how black holes grow over time may have found the answer to one of the biggest problems in cosmology.
Explaining the “universe breaker” galaxies discovered by the James Webb Telescope
Astronomers report recent observation of six massive galaxies that according to our current understanding of the Universe should not exist at all.
Itokawa asteroid is a rubble pile that could be tough to destroy
Analysis of dust particles collected from the surface of the 500-meter-long asteroid has implications for planetary defense.
Searching for dark matter in our solar system
Sending atomic and nuclear clocks into the inner reaches of our solar system could help scientists find proof of elusive dark matter.
How accurate are our models of rotating neutron stars?
Comparing algorithms used to model spinning neutron stars, scientists hope to better understand the physics of the elementary particles that make them up.
NASA’s Lunar Flashlight Spacecraft may be in deep space trouble
Three of the briefcase-size satellite’s thrusters are underperforming, jeopardizing its journey to the Moon.
Detecting ultralight dark matter particles using supermassive black holes
Is it time to start looking for alternatives to WIMPs?
Explaining the Universe’s accelerated expansion without dark energy
A modification to the theory of general relativity makes it consistent with observable astronomical data without the need for dark energy.
New type of black hole merger may have just been observed
Merging pairs of black holes are thought to have originated from binary stars, but new observations indicate this might not always be true.
