First Detection of Inverse Compton Emission From Dying Gamma-Ray Burst A dying star emits intense flashes of light called a gamma-ray burst. Most days, the…
Second fastest spinning radio pulsar known is a gamma-ray pulsar, too. Multi-messenger observations look closely at the system and raise new questions. An international research…
If our eyes could see high-energy radiation called gamma rays, the Moon would appear brighter than the Sun! That’s how NASA’s Fermi Gamma-ray Space Telescope…
A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio…
Astronomers found a pulsar hurtling through space at nearly 2.5 million miles an hour — so fast it could travel the distance between Earth and…
Scientists using data from NASA’s Fermi Gamma-ray Space Telescope have measured all the starlight produced over 90 percent of the universe’s history. The analysis, which…
In 2017, NASA’s Fermi Gamma-ray Space Telescope played a pivotal role in two important breakthroughs occurring just five weeks apart. But what might seem like…
Long ago, sky watchers linked the brightest stars into patterns reflecting animals, heroes, monsters and even scientific instruments into what is now an official collection…
An international team of scientists studying what amounts to a computer-simulated “pulsar in a box” are gaining a more detailed understanding of the complex, high-energy…
Astronomers typically study objects that are visible night after night or explode suddenly, like supernovas, but Casey Law is scouring vast amounts of data in…
An international collaboration operating NASA’s NuSTAR satellite has revealed that two of the biggest stars in the galaxy are capable of creating cosmic rays. Their…
The “ghostly particle” is confirmed to have originated from a blazar, nearly 4 billion light years from Earth. For the first time, scientists from around…
For the first time ever, scientists using NASA’s Fermi Gamma-ray Space Telescope have found the source of a high-energy neutrino from outside our galaxy. This…
Astronomers and physicists around the world, including in Hawaii, have begun to unravel a long-standing cosmic mystery. Using a vast array of telescopes in space…
A new study using data from NASA’s NuSTAR space telescope suggests that Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is…
New model connects the origins of very high-energy neutrinos, ultrahigh-energy cosmic rays, and high-energy gamma rays with black-hole jets embedded in their environments. One of…
An international team of scientists reveals in the journal Nature that the neutron-star merger announced in October has solved one mystery, where gold comes from,…
