Fermi spots a supernova’s ‘fizzled’ gamma-ray burst
On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half...
A bug’s life: Millimeter-tall mountains on neutron stars
New models of neutron stars show that their tallest mountains may be only fractions of millimeters high, due to the huge gravity on the...
How the universe is reflected near black holes
When a black hole passes between us and a distant galaxy, the galaxy may be fine, but its image may never escape. Since light...
Physicists observationally confirm Hawking’s black hole theorem for the first time
Study offers evidence, based on gravitational waves, to show that the total area of a black hole’s event horizon can never decrease.
There are certain...
A white dwarf living on the edge
Astronomers have found a stellar corpse often called a white dwarf that’s roughly the scale of Earth’s moon. White dwarfs are the collapsed remnants...
Mystery of Betelgeuse’s dip in brightness solved
A team of astronomers have now published new images of the star’s surface, taken using the European Southern Observatory’s Very Large Telescope (ESO’s VLT),...
The sun’s clock: New calculations support and expand planetary hypothesis
Not only the 11-year cycle, but also all other periodic solar activity fluctuations can be clocked by planetary attractive forces. With new model calculations,...
Study reveals new details on what happened in the first microsecond...
The first microsecond of Big Bang is a mystery. Studies determine the only matter that existed during the occurence of the Big Bang called...
New research reveals hidden processes at work in the hearts of...
Looking into the hearts of large stars is tricky. Researchers discover that as the core of massive stars there is an activity that is...
