Upper ocean temperatures hit a new record in 2020
Even with the COVID-19-related small dip in global carbon emissions due to limited travel and other activities, the ocean temperatures…
Axions might be the source of X-ray emissions surrounding neutron stars
The axion makes an excellent dark matter candidate. Confirming that axions are real would be a breakthrough for particle physics—and…
Physicists Discover a New Way to Extract Energy From Black Holes
For the last 50 years, scientists have tried to come up with methods to unleash this power. Nobel physicist Roger…
A Study Reveals How Black Holes Grow Rapidly After Galactic Collisions
Astronomers want to learn more about galactic collisions because the subsequent mergers are a key way that galaxies and the…
The first evidence of top quark production in nucleus-nucleus collisions
Quarks are the heaviest elementary particles known to date. They can be studied in heavy-ion collisions. At the time, it…
What can two stars like Mu Cephei (above) and 119 Tauri (below) have in common?
You can easily understand this by comparing the two images. Both have an intense red color: Mu Cephei and 119…
Direct Measurements of Pulsar Acceleration Reveal Nature of Milky Way’s Dark Matter
In a new study to be published in Astrophysical Journal Letters researchers have now obtained the first direct measurement of…
New Quasar Discovery Beats the Set Distance Record
The quasar, called J0313-1806, is seen as it was when the Universe was only 670 million years old and is…
Ruling Out Dark Matter Decay
Sterile neutrinos are currently the leading candidate for dark matter. These hypothetical massive cousins of the neutrino should decay and…
