On October 3, 2018, cell phones across the United States received a text message labeled "Presidential Alert." The message read: "THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed." It was the first...
An international research team led by the University of Göttingen has discovered two new Earth-like planets near one of our closest neighboring stars. "Teegarden's star" is only about 12.5 light years away from Earth and is one of...
The Sun is why we're here. It's also why Martians or Venusians are not. When the Sun was just a baby four billion years ago, it went through violent outbursts of intense radiation, spewing scorching, high-energy clouds and particles...
If you've ever pressed a picture-hanging strip onto the wall only to realize it's slightly off-center, you know the disappointment behind adhesion as we typically experience it: it may be strong, but it's mostly irreversible. While you can...
For 10 years, NASA's Fermi Gamma-ray Space Telescope has scanned the sky for gamma-ray bursts (GRBs), the universe's most luminous explosions. A new catalog of the highest-energy blasts provides scientists with fresh insights into how they work. "Each burst...
A familiar ingredient has been hiding in plain sight on the surface of Jupiter's moon Europa. Using a visible light spectral analysis, planetary scientists at Caltech and the Jet Propulsion Laboratory, which Caltech manages for NASA, have discovered...
If astronomers want to learn about how supermassive black holes form, they have to start small -- really small, astronomically speaking. In fact, a team including University of Michigan astronomer Elena Gallo has discovered that a black hole at...
Researchers at CU Boulder have discovered hints that humanity's favorite star may have a dual personality, with intriguing discrepancies in its magnetic fields that could hold clues to the sun's own "internal clock." Physicists Loren Matilsky and Juri Toomre...
Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares. These events occur when stars, for reasons that scientists still don't understand, eject huge bursts...
The newly-discovered dark dwarf galaxy Antlia 2's collision with the Milky Way may be responsible for our galaxy's characteristic ripples in its outer disc, according to a study led by Rochester Institute of Technology Assistant Professor Sukanya Chakrabarti. The...
