This image is a horizontal rectangle, with a representation of the Einstein Probe spacecraft in the middle. The spacecraft has a golden colour and looks like multiple stacked boxes with dark panels sticking out on either side (solar arrays). On the top right of the image, an explosion is visible as a yellow ball with spikes sticking out of it. A green beam goes from the explosion into the spacecraft. Behind the explosion, the night sky is visible and a yellow high-light represents a window to the far-away Universe with a yellow grid, which is a representation of Einstein Probe’s lobster-eye optics. Behind the spacecraft, Earth is visible as a half globe, in a purple-blue hue. On the bottom of the image, multiple dishes are visible in yellow-green, which represent telescopes on the ground.

Somehow, a Tiny Black Hole Is Causing a ‘Heartbeat’ 100 Light-Years Away

There’s a cloudy patch of space inside our galaxy that unexpectedly produces gamma radiation at clockwork-like intervals. Scientists have now linked these periodic pulses to a “microquasar”—most likely a black hole—located a whopping 100 light-years away, in what is an extraordinary observation. New research published today in Nature Astronomy describes an unusual long-distance relationship involving…

Dark Matter ‘Strikes Back’ in Galactic Mystery

Dark matter could be responsible for the mysterious observation of gamma rays in the center of our galaxy, according to a new paper. Astrophysicists have known for a decade that the center of the Milky Way is sending too many gamma rays our way. Mysterious stuff called dark matter was once considered the prime candidate…

Strongest Gamma-Ray Bursts Ever Recorded Are Illuminating the Universe’s Most Powerful Explosions

An international team of astronomers has detected a pair of gamma-ray bursts with energies more powerful than anything ever seen before. GRBs are the strongest explosions known in the cosmos, but these latest observations suggests we’ve significantly underestimated their true potential. Three new papers published today in Nature describe two new gamma-ray bursts—GRB 190114C and…

The Moon Shines Brighter Than the Sun… in Gamma Rays

The Moon is brighter than the Sun, if you’re measuring it in gamma rays. Sorta. NASA publicized this interesting factoid in a press release last week while promoting research by physicists Mario Nicola Mazziotta and Francesco Loparco at the National Institute of Nuclear Physics in Italy, who made observations using the Fermi Gamma-ray Space Telescope.…

Incredible Observation Links Two Different Radioactive Phenomena Inside a Thunderstorm

Scientists in Japan reported seeing two radioactive weather phenomena at the same time, for the first time, according to a new paper. The observation establishes a link between the two, adding to our knowledge of the wild physics that takes place inside thunderstorms. The researchers reported the “unequivocal simultaneous detection” of a minute-long “gamma-ray glow”…

Why Scientists Tried to Measure All of the Starlight That Ever Shone

Astronomers this week announced that they’d attempted to measure all of the starlight in the universe. You might wonder why. Ultimately, they’re trying to tell the universe’s story. “We wanted to know how star formation history proceeded,” Kari Helgason, scientist at the Max Planck Institute for Astrophysics in Germany, told Gizmodo. The entire universe is…

Every so often, protons and even entire atomic nuclei strike the Earth with extremely high energies—much higher than what scientists can produce in their most powerful physics experiments. Since the discovery of “cosmic rays” a hundred years ago, no one knew for sure where the most energetic of these particles came from—until now. On Thursday,…
