Universe goes on diet of electrons, weight may stay off
By: William Atkins
Astronomers at the University of Alabama (Huntsville, U.S.A.) and the Helsinki Observatory (Finland) found that X-rays coming from galaxy cluster Abell 3112 originate from electrons and photons. If this conclusion holds with other galaxy clusters, it will considerably reduce the mass of the universe.

GalaxyZoo finds most galaxies in universe are left-handed
By: William Atkins
Based on conclusions from over one-hundred-thousand GalaxyZoo volunteers as part of the Sloan Digital Sky Survey project, most galaxies seem to be rotating counterclockwise in relation to the Earth. Astronomers wonder why?

Comet Holmes gains brightness, now looks brighter than Jupiter
By: William Atkins
After a million-times increase in brightness over a two-day period beginning on October 24, 2007, Comet 17P/Holmes has now increased its luminosity even more, looking brighter than the planet Jupiter.

Orionids meteor shower set for Oct. 21-22, 2007
By: William Atkins
The meteor display called the Orionids, from parent body Halley’s Comet, is expected to be clearly visible in the dark skies away from light pollution and urban lights early in the morning just before sunrise. If the display is like last year it should produce about 20 to 60 meteors per hour.

Hubble snaps brilliant image of young star cluster inside NGC 3603
By: William Atkins
The NASA/ESA Hubble Space Telescope has produced an image of a star cluster that contains stars with different masses but similar ages. The stars have evolved differently, making it easy for scientists to learn more about the various life-stages of stars from one location.

West Virginia undergrad makes discovery of possible new space object
By: William Atkins
West Virginia University undergraduate student David Narkevic was looking at old radio data taken from an Australian radio telescope when he found something that looked like a very short and powerful burst of radio energy from a pulsar—but it wasn’t from a pulsar. So what is it?

Hubble loses another gyroscope but keeps on ticking
By: William Atkins
On September 1, 2007, gyroscope Gyro 2 failed on board the Hubble Space Telescope (HST). With a NASA repair mission scheduled for August 7, 2008, Hubble will have to operate until that time with only two gyros.

Hard X-ray astronomy gets a HERO
By: William Atkins
X-ray astronomy is difficult for astronomers because high-energy X rays are so energetic that instead of bouncing off ordinary mirrors they pass right through them. Telescopes cannot use such mirrors but must rely on nearly parallel mirrors called grazing incidence mirrors. That’s where the HERO comes in to save the day.

Lucky camera, Palomar telescope takes sharper space photos than Hubble
By: William Atkins
The Lucky Imaging System (“Lucky”), developed by U.S. and U.K. astronomers, uses a new adaptive optics system, which is able to take out much of the distortion from Earth’s atmosphere, in order to produce some of the best digital images from ground telescopes.
