This week, ESA’s Integral space observatory celebrates ten years since launch on 17 October 2002.

Supernova Lights Up The Galactic Scene

A recent study, led by Edo Berger of Harvard University, made the most of a dying star's fury to probe a distant galaxy some 9.5 billion light years away. The most distant stellar explosion of its kind ever studied, that dying star lit up the galactic scene.

The 'FLOYDS' Spectrographs Acquire Target Robotically At Las Cumbres Observatory

Two identical FLOYDS spectrographs, installed in recent weeks at telescopes 6,000 miles apart, robotically acquired a supernovae target this week.

Spacetime Is Smooth, Not Foamy

Scientists have long believed that spacetime is foamy, like a freshly pulled draft beer, but new information from an intergalactic photo finish shows it might just be as smooth as a single malt whiskey, instead.

Fermi Reveals Gamma-ray Bursts' Highest Power Side

Detectable for only a few seconds but possessing enormous energy, gamma-ray bursts are difficult to capture because their energy does not penetrate the Earth's atmosphere.

Gamma-Ray Astronomy -- Gamma-ray astronomy is the astronomical study of gamma rays. Long before experiments could detect gamma rays emitted by cosmic sources, scientists had known that the universe should be producing these photons. Work by Feenberg and Primakoff in 1948, Hayakawa and Hutchinson in 1952, and, especially, Morrison in 1958 had led scientists to believe that a number of different processes which were occurring in the universe would result in gamma-ray emission. These...

Hypernova -- A hypernova is a theoretical type of supernova produced when exceptionally large stars collapse at the end of their lifespan. In a hypernova, the core of the star collapses directly into a black hole and two extremely energetic jets of plasma are emitted from its rotational poles at nearly light speed. These jets emit intense gamma rays, and are a candidate explanation for gamma ray bursts. Theorists have come up with several plausible explanations for hypernovae. It may...

Gamma-Ray Burst -- In astronomy, Gamma-ray bursters (GRBs) are flashes of gamma rays that last from seconds to hours, the longer ones being followed by several days of X-ray afterglow. They occur at random positions in the sky several times each day. They are now believed to result from tremendous explosions in far away galaxies, during the creation of a black hole from a dying star or two colliding neutron stars. The black hole, surrounded by a rotating disk of matter falling into it,...
