Glimpsing the infrastructure of a gamma-ray burst jet

(Phys.org) —A new study using observations from a novel instrument provides the best look to date at magnetic fields at the heart of gamma-ray bursts, the most energetic explosions in the universe. An international team ...

Astronomers reveal mystery of brightest ever gamma-ray burst

For the first time, a team of astronomers from around the world, including experts from the University of Leicester, have used data from satellites and observatories to explain the brightest Gamma-ray Burst (GRB) ever recorded.

Study shows alpine swift can stay aloft for 200 days

(Phys.org) —A combined team of researchers from Bern University and the Swiss Ornithological Institute has found that alpine swifts are able to fly for up to 200 days at a time, without landing. The team learned of the ...

A strong magnetic field around the Milky Way's black hole

(Phys.org) —Astronomers have made an important measurement of the magnetic field emanating from a swirling disk of material surrounding the black hole at the center of our Milky Way Galaxy. The measurement, made by observing ...

Earth's gold came from colliding dead stars

We value gold for many reasons: its beauty, its usefulness as jewelry, and its rarity. Gold is rare on Earth in part because it's also rare in the universe. Unlike elements like carbon or iron, it cannot be created within ...

Fermi and Swift see 'shockingly bright' burst

A record-setting blast of gamma rays from a dying star in a distant galaxy has wowed astronomers around the world. The eruption, which is classified as a gamma-ray burst, or GRB, and designated GRB 130427A, produced the highest-energy ...

Black hole wakes up and has a light snack

(Phys.org) —Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object – either a brown dwarf or a giant planet – that strayed too close. A similar feeding event, albeit ...
