Try, try again
NASA announced October 23 that, despite a series of setbacks, the prognosis is good for reviving the Hubble Space Telescope.
- Space
New light on moon water
Kaguya, a Japanese spacecraft orbiting the moon, finds that a south pole crater called Shackleton has no visible signs of ice.
- Space
More problems with Hubble
Hubble’s resurrection is suspended while engineers examine two anomalies.
- Space
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.
- Planetary Science
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.
- Space
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.
- Planetary Science
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.
