Supernova Remnant N 63A Menagerie
A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant.
Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an alread...
On Jan. 10, 2008, a 1.2 km-wide asteroid, 2005 WJ56, will make a close flyby (2.6 million miles, 10.9 lunar distances) of the Earth. The asteroid will appear as a magnitude 11.6 star in the constellation Taurus. Ephemeris pre>Date TT R. A. (2000) Decl. Delta r Elong. Phase V 2008 01 05 07 27.69 +62 27.3...

A conversation about wanting the window seat over the aisle in an airplane reminded me of this photograph I took when flying into Austin. About 40 miles southeast of Austin a large (I mean very large) plot of land has been cleared so that the remaining trees spell out "LUECKE" - the landowne...
Almost exactly 200 years ago, sodium was isolated as an elemental metal during electrolysis of molten sodium hydroxide (caustic soda). This was announced on November 19, 1807, by Sir Humphry Davy, in the Bakerian Lecture of the Royal Society, along with another new alkali metal, potassium (from m...
Title: The discovery of high-amplitude 10.9-minute oscillations in the cool magnetic Ap star HD 115226 Authors: O. Kochukhov, T. Ryabchikova, S. Bagnulo, G. Lo Curto We present the discovery of pulsational variations in the cool magnetic Ap star HD 115226 -- the first high-amplitude rapidly osc...
Astronomers have known for decades that supermassive black holes at the cores of galaxies can shoot out jets of subatomic particles at tremendous speeds. However, details about the physics of such jets, including how they are generated, how the high-speed flows are shaped into jets, and how fast t...
Exoplanets are of high interest, not only because questions regarding alien life in the universe have accompanied humanity for a long time, but also because studying exoplanetary systems allows to study the past and the future of our own solar system. The first V 391 Peg b was discovered 15 years ago...
The Hubble Space Telescope's powerful vision has resolved strange objects nicknamed "blue blobs" and found them to be brilliant blue clusters of stars born in the swirls and eddies of a galactic smashup 200 million years ago. Such "blue blobs" weighing tens of thousands of s...
