Title: Two Extrasolar Asteroids with Low Volatile-Element Mass Fractions Authors: M. Jura (1), S. Xu (1), B. Klein (1), D. Koester (2), B. Zuckerman (1), ((1) UCLA, (2) University of Kiel) Using ultraviolet spectra obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope, we e...
A team of astronomers have used an ESO (European Southern Observatory) telescope to measure the distance to a star, using the help of light echoes. The star, known as a Cepheid, belongs to a class of variable stars that constitute one of the first steps in the distance scale of the Universe. "Our...
The sun has some weird next-door neighbours.
Astronomers using the Hubble Space Telescope and the W.M. Keck Observatory on Mauna Kea have produced images of a huge, lopsided disk of debris around a nearby star.
They are calling it the "blue needle" because of the appearance of the di...
Daya Bay Reactor Neutrino Experiment Work has begun on a new experiment in China to study the ubiquitous and ultra-inert sub-atomic particles known as neutrinos. The aim of the $32m experiment, which is a joint effort between physicists from China and the US, is to improve the measurement of one of t...

We are deeply saddened to announce that Celestron founder, Thomas J. Johnson, passed away at 5am PST on March 13, 2012. Tom's innovative, pioneering spirit created a revolutionary method of mass producing an affordable Schmidt-Cassegrain telescope design, which allowed millions of amateur as...
Frank Frederick Borman, II (born March 14, 1928) is a retired NASA astronaut and engineer, best remembered as the Commander of Apollo 8, the first mission to fly around the Moon, making him, along with fellow crew mates Jim Lovell and Bill Anders, the first of only 24 humans to do so. Read more
The Second Equirria (Festival of Mars - held on March 14) was a holy day with religious and military significance at the end of the new year celebrations for Mars. Read more
NASA and CSA Robotic Operations Advance Satellite Servicing NASA's Robotic Refuelling Mission (RRM) experiment aboard the International Space Station has demonstrated remotely controlled robots and specialised tools can perform precise satellite-servicing tasks in space. The project...
Title: Auto-consistent metallicity and star formation history of the nearest blue compact dwarf galaxy NGC 6789 Authors: Rubén García-Benito, Enrique Pérez-Montero We present a detailed auto-consistent study of the nearest blue compact dwarf galaxy NGC 6789 by means of optical and UV archive...
Cassini Spies Wave Rattling Jet Stream on Jupiter New movies of Jupiter are the first to catch an invisible wave shaking up one of the giant planet's jet streams, an interaction that also takes place in Earth's atmosphere and influences the weather. The movies, made from images taken by NASA's Cassi...
Title: A z~3 radio galaxy and its protocluster: evidence for a superstructure? Authors: E. Kuiper, B. P. Venemans, N. A. Hatch, G. K. Miley, H. J. A. Rottgering We present spectroscopic follow-up observations of Lyman Break Galaxies (LBGs) selected in the field surrounding the radio galaxy MRC03...
Giovanni Virginio Schiaparelli (March 14, 1835, Savigliano - July 4, 1910) was an Italian astronomer and science historian. He studied at the University of Turin and Berlin Observatory. In 1859-1860 he worked in Pulkovo Observatory and then worked for over forty years at Brera Observatory. Amon...
Title: X-Ray Observations of the Supernova Remnant W28 with Suzaku --- I. Spectral Study of the Recombining Plasma Authors: Makoto Sawada, Katsuji Koyama We present the Suzaku results of the mixed-morphology supernova remnant W28. The X-ray spectra of the central region of W28 exhibit many brig...
