A new look at the gamma-ray sky
Explosions pouring out as much energy in seconds as the sun does in its entire lifetime. Invisible beams of radiation sweeping across the sky like giant searchlights. Supermassive black holes emitting powerful and highly variable jets of radiation. GAMMA GLOW Simulation of the high-energy sky that will be seen by GLAST. Sonoma State, NASA The […]

Flooring the cosmic accelerator
If cosmologist Will Percival of the University of Portsmouth in England is right, the universe will end about 60 billion years from now, when every molecule and atom will be torn asunder by a mysterious entity that opposes gravity’s pull and turns it into a cosmic push.
- Astronomy
Honing the Hubble
Astronomers are sharpening measurements of a familiar cosmic parameter to shed new light on dark energy, the mysterious entity that’s accelerating the universe’s rate of expansion.

Supermassive black hole says sayonara
Researchers have the first observational hint for the existence of an ejected supermassive black hole, fired by a gravitational rocket from the core of the galaxy in which it formed.
- Astronomy
Massive minis
Astronomers have discovered a puzzling group of galaxies in the early universe that are as tiny as babies but as massive as full-grown adults.

Hop, skip and a jump
Less gravity on Mars means wind-driven grains of sand travel up to 10 times faster than those blowing along Earth’s surface, new analyses suggest.
- Space
Searching for superEarths
Astronomers are exploring a new family of planets beyond the solar system.
