Macworld 2010: Controlling a telescope via iPhone

At Macworld 2010 in San Francisco, Tim DeBenedictis, product architect of Carina Software, unveils the company's SkyVoyager iPhone app, which enables users to find stars, clusters, and galaxies in the night sky. He also demos SkyFi, a device that offers users the ability to use their iPhone as a telescope controller.

Inside an early star-forming galaxy

U.S. astronomers from the California Institute of Technology (Caltech) have used adaptive optics (AO) on the 10-meter Keck Telescope in Hawaii in conjunction with other images provided by the Hubble Space Telescope to look inside a young star-forming galaxy as it appeared only two billion years after the Big Bang. The team made their observations by coupling two techniques, gravitational lensing and laser-assisted guide star (LGS) adaptive optics. 'Adaptive optics corrects the blurring effects of Earth's atmosphere by real-time monitoring of the signal from a natural guide star or an artificial guide star.' But read more...

Ghostly ring found circling dead star

An international team of scientists has found a strange ring around a dead star by using images taken by NASA's Spitzer space telescope. This star, called SGR 1900+14, belongs to a class of objects known as magnetars. According to NASA, a magnetar is 'a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.' So far, about a dozen magnetars have been found. An amazing thing about these stellar objects is their magnetic field. One of the researchers said that 'magnetars possess magnetic fields a million billion times stronger than the magnetic field of the Earth.' But read more...

Microsoft's Worldwide Telescope

Microsoft's Worldwide Telescope, a virtual map of outer space, is within months of its public debut. CNET News.com's Kara Tsuboi talks with the space exploration program's founder, Curtis Wong, and shares video of what these celestial tours will look like.

Making the sky searchable

Computer scientists at the University of Toronto (U of T) have teamed up with astronomers at New York University on an ambitious project. You can send them a picture of the sky above your head and their special software will identify the stars that are in the image. In other words, their computer program will make night sky searchable. The team is organizing and mixing images coming from astronomical databases with images coming from 'all kinds of cameras, amateur telescopes, large ground-based telescopes, and space telescopes such as the Hubble Space Telescope.' This specialized search engine is still in beta-version, but is available to both professional and amateur astronomers.

Microshutters for the Webb Space Telescope

In case you don't remember, the Webb Space Telescope will replace Hubble, probably after 2011, and should be able to catch phenomena which happened 13.5 billion light-years ago. At these distances, the instruments onboard will need to be more precise than ever. This is why NASA has developed a new technology based on microshutters for a better focus of distant galaxies. These arrays of microshutters, composed of more than 62,000 individual shutters measuring 100 by 200 microns, will allow scientists to systematically block out light that they do not want, allowing the large-format detector to measure infrared spectra optimally.

The first 3D map of dark matter

In a letter to Nature, an international team of researchers reveals it has produced the first 3D picture of dark matter. This map has been created by combining hundreds of images taken by the Hubble Space Telescope for the Cosmic Evolution Survey (COSMOS). As the cosmologists were expecting, this map, which represents about half a million distant galaxies, shows that dark matter forms a kind of skeleton which can attract baryonic particles -- such as protons and neutrons -- to produce stars and galaxies. But this is not always the case, and the researchers are now working to find the origin of these discrepancies.

Take my CPU, please

Many of us at CNET do double duty by scouting the galaxy for aliens--usually while we're at lunch. The SETI@Home screensaver, which analyzes radio telescope data from Puerto Rico's Arecibo Observatory, works using distributed computing, harnessing the power of thousands of computers to crunch reams of data. Now, however, other companies are fighting for space on our hard drives. And, predictably, they're trying to make a buck in the process. In this week's Insider, editor Steve Fox alerts us to some of the more uncharitable aspects of the emerging distributed-computing trend.
