Supernova Outbreak
Thanks to a lucky break and an overactive galaxy, astronomers report the earliest detection yet of a normal supernova—the explosive death of a massive star.

Twisted roots for solar jets
Researchers have constructed the first 3-D image of a jet of gas zooming out of the sun's outer atmosphere, revealing the role that twisted magnetic fields play in generating such outbursts.
- Astronomy
Galaxy’s youngest supernova
Astronomers have found the youngest Milky Way supernova remnant ever recorded from Earth.
- Space
A shifty moon
Astronomers have found evidence that the icy shell of Jupiter's large moon Europa has rotated nearly a quarter-turn, which supports the notion that the moon has a subterranean ocean.

John Wheeler (1911-2008)
SN Editor in Chief Tom Siegfried remembers the late physicist John Wheeler, who coined the term "black hole" in 1967, with excerpts from conversations the two had engaged in over the past two decades.

A special place
Two proposed studies might determine whether dark energy is real or humans live in a special place in the cosmos

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.
