A Meteoroid Hits the Moon
This NASA Web page describes observations of a recent meteoroid impact on the moon, which created a new crater. It includes audio and a remarkable video of the impact. Go to: http://science.nasa.gov/headlines/y2006/13jun_lunarsporadic.htm?list43643

Explosive Aftermath: Sluggish neutron star puzzles astronomers
An X-ray–emitting object at the heart of a young supernova remnant doesn't fit the textbook view of what a stellar explosion is supposed to leave behind.

Repaired Vision: Hubble’s camera sees again
The main camera on the Hubble Space Telescope is operating normally again after being blinded for 2 weeks by an electrical failure.
- Planetary Science
Lots of red dust, but not much noise
In space, no one can hear you scream, but a new analysis suggests that it's pretty quiet on Mars, too.
- Astronomy
Astronomy Gets Polarized
Studies using polarized light, an endeavor once considered astronomy's stepchild, are now elucidating the shape of supernovas as well as providing new details about the early universe.
- Astronomy
Planet-making disk has a banana split
Two banana-shaped arcs of gas and dust face each other within a newly discovered planet-forming disk that surrounds a young, nearby star.
- Astronomy
Galactic de Gustibus
About 13 billion years after its birth, our galaxy is still packing on the stars.
- Astronomy
Magnetic Thrust: Fields force matter into black holes
New observations confirm that magnetic fields provide matter with the last push to plunge into a black hole.
- Astronomy
Not a planet?
New observations add to the evidence that an image of a planetary-mass object discovered beyond the solar system is not that of a bona fide planet.
- Astronomy
Spewing superdust
Astronomers have identified a type of supernova as the main source of space dust.
- Astronomy
Mini Solar Systems? Astronomers find disks around planet-size objects
Disks with the potential to form planets, or at least moons, have been found orbiting objects outside the solar system that themselves are no heftier than planets.
- Planetary Science
The sands of Titan
Although the surface of Saturn's moon Titan is cold enough to freeze methane, it has sand dunes like those in the Arabian Desert, according to radar images taken by the Cassini spacecraft.
