An meteorite that crashed in the Sierra Nevada mountains in April was traveling at the fastest speed on record for an meteorite, almost 18 miles per second.
The bar at the center of the Milky Way.
Another Earth just twelve light years away?
Watch a three mile wide asteroid fly past the Earth – live tonight from 5 to 11 pm (Eastern)!

O goody: The GAO is concerned about the future budget and schedule of the James Webb Space Telescope.
This is very bad news if true for NASA’s astronomy program. Webb was originally budgeted at $1 billion and scheduled to launch in 2011. Its budget is now $8.8 billion and its launch is now set for October 2018. And until it launches there is little money to build any other space telescope.
The newly launched Andromeda Project will use people power to examine thousands of Hubble Space Telescope images of the galaxy to identify star clusters that hold clues to the evolution of galaxies. Anyone can take part by going to The Andromeda Project.
The biggest black hole yet found, 17 billion times the mass of our sun.
The unusual black hole makes up 14 percent of its galaxy’s mass, rather than the usual 0.1 percent. … NGC 1277 [the galaxy] lies 220 million light-years away in the constellation Perseus. The galaxy is only ten percent the size and mass of our own Milky Way. Despite NGC 1277’s diminutive size, the black hole at its heart is more than 11 times as wide as Neptune’s orbit around the Sun.
Based on these measurements, it appears that this black hole is literally eating this galaxy whole.
NASA is soliciting ideas on how to use the two Cold War era telescopes given to the space agency by the military.
Both telescopes are comparable in size to the Hubble Space Telescope.
Impressive radar images of near-Earth asteroid 2007 PA8 were taken during its recent fly-by of Earth.
The images … reveal possible craters, boulders, an irregular, asymmetric shape, and very slow rotation. The asteroid measures approximately one mile wide (about 1.6 kilometers).
The asteroid poses no threat to Earth. The resolution of the images, however, is astonishing, especially considering it was done by radar.
An exhumation of the body of Danish astronomy Tycho Brahe has proven he was not murdered as speculated by some.
