WISE Views Aging Star Erupting With Dust It's a dust bunny of cosmic proportions. Astronomers used images from NASA's Wide-field Infrared Survey Explorer, or WISE, to locate an aging star shedding loads of dust (orange dot at upper left). Only one other star, called Sakurai's object, has been caught erupting with such large amounts of dust. The process is a natural part of aging for stars like our sun. As they puff up into red giants, they shed dust that is later recycled back into other stars, planets, and in the case of our solar system, living creatures.

In examining atomic structure though, we have to clarify this statement. An atom cannot be broken down further without changing the chemical nature of the substance.

Darkest exoplanet spotted by astronomers 12 August 2011Last updated at 11:09 By Jason Palmer Science and technology reporter, BBC News TrES-2b is literally darker, on average, than coal A dark alien world, blacker than coal, has been spotted by astronomers. The Jupiter-sized planet is orbiting its star at a distance of just five million km, and is likely to be at a temperature of some 1200C. The planet may be too hot to support reflective clouds like those we see in our own Solar System, but even that would not explain why it is so dark. The research will be published in the journal Monthly Notices of the Royal Astronomical Society.

Explore the Night Sky With Stellarium Have you ever looked up at the night sky wondering where those elusive constellations are? Do you wonder what that really bright star (or planet) is called? With Stellarium, you will wonder no longer! You may have heard of Celestia, a great program that lets you leave planet Earth and explore space from beyond. Stellarium is similar to Celestia in some ways, but it allows you to view and explore the night sky exactly as it would appear from any location on Earth. Like Celestia, it is also available for Linux, Mac OS X, and Windows.

The birth of a baby star: NASA acts as midwife to watch new creation burst into life By Eddie Wrenn Published: 14:06 GMT, 13 July 2012 | Updated: 14:18 GMT, 13 July 2012 Like an intergalactic midwife, NASA has been carefully monitoring a stellar infant still partly swaddled in its birth cloud. Using combined data from a trio of orbiting X-ray telescopes, astronomers have obtained a rare glimpse of the powerful phenomena that accompany a still-forming star. The space agency is monitoring star 'V1647 Orionis', and have watched as intense magnetic fields drive torrents of gas into the stellar surface, where they heat large areas to millions of degrees.

Periodic Table of the Elements Aluminium: the essentials Pure aluminium is a silvery-white metal with many desirable characteristics. It is light, nontoxic (as the metal), nonmagnetic and nonsparking. It is somewhat decorative. It is easily formed, machined, and cast. 5 Really Weird Things About Water Water, good ol' H2O, seems like a pretty simple substance to you and me. But in reality, water - the foundation of life and most common of liquid - is really weird and scientists actually don't completely understand how water works. Here are 5 really weird things about water:
