A new instrument made a short jaunt to space on the weekend, as part of a mission to measure the total light ever emitted over the universe’s history. The CIBER-2 project will search for stray stars ...

A telescope in Tibet consisting of plastic detectors and underground water vat observed the highest-energy light yet—and it came from one of the most famous light sources in the sky. For the first ...

The universe has been making stars for a good 13 billion years or so, and a natural question to ask might be "how many stars have existed in that time?" But now astronomers have taken it several steps ...

A group of international researchers has discovered the highest-energy light ever observed from the sun. In a new paper published last week in the journal Physical Review Letters, scientists found the ...

NASA's NuSTAR space observatory revealed the highest-energy light ever detected from Jupiter, solving a 30-year old mystery in the process. The Ulysses mission did not detect the high-energy light, as ...

Scientists have been studying Jupiter up close since the 1970s, but the gas giant is still full of mysteries. New observations by NASA’s NuSTAR space observatory have revealed the highest-energy light ...

The sun's rays may be stronger than scientists previously thought, new research suggests. Using a highly sophisticated telescope, a team of researchers recorded the highest-energy light ever detected ...

High up on the Tibetan plateau, scientists just measured the most energetic light ever seen. These photons were gamma rays with energies exceeding 100 trillion electronvolts — one even had nearly 500 ...
