Hubble revives
A plan to switch the Hubble Space Telescope to a backup system works, waking up the telescope after more than two weeks of silence.

Huge cyclone churns at Saturn’s north pole
Planetary scientists have gotten their closest look yet at polar storms on the ringed planet. These polar cyclones are big enough to engulf Earth.

Hubble, heal thyself
NASA scientists are cleared to remotely switch equipment on the Hubble Space Telescope in the hopes of restoring the orbiting observatory’s function by October 16.

So close, yet so far away
Astronomers have found, in the frozen reaches beyond Neptune, two gravitationally bound objects that compose the most widely spaced binary system known in the solar system.
- Space
A comet doubleheader
Astronomers have discovered the first comet that appears to be a contact binary — two chunks somehow held together by a narrow neck of material.
- Space
Askew in the outer solar system
A chunk of ice orbiting backwards around the sun could offer hints about the mysterious origin of some comets.
- Space
Sniping at Jupiter
Giant Jupiter, often thought to protect the inner planets from space debris, may sometimes acts as a sniper, hurling material toward Earth.

Ultramassive: as big as it gets
A black hole can consume anything in its path. These monsters can become huge — but perhaps only so huge.

On that ‘earmark’ for my favorite science center
Featured blog: In the last debate, McCain denounced proposed federal spending on a multimillion dollar "overhead projector."
- Planetary Science
New angles on Mercury
The NASA MESSENGER spacecraft completed its second flyby of Mercury, yielding crisp new images of a large swath of the planet not seen before.

No naked black holes
In a simulated merger, astrophysicists tried to push the boundaries of two black holes into shedding their event horizons. But the resulting black hole was still shrouded by its event horizon, through which even light can’t escape.
