Medieval skywatchers got to see a star explode, but modern-day astronomy buffs get all the pretty pictures of its ghostly remains.

Biological Sciences in LIGHT

The cross-faculty nature of LIGHT is represented by both the collaborations within Multidisciplinary Cardiovascular Research Centre and the co-location of researchers from the Faculties of Medicine and Health and that of Biological Sciences in the LIGHT laboratories. This interdisciplinary approach, integrating basic science and clinical research, is a strong feature of the LIGHT laboratories. A number of research areas are covered by Biological Sciences staff in LIGHT in relation to the overall research strategy of the Institute and these are introduced briefly below.

New "Sunglasses" Help Astronomers See Light Near Black Holes

Although we can't actually see a black hole, we can see the black hole's effect on nearby matter. But even that is difficult because infrared light from clouds of dust and gas usually pollutes the view. But astronomers have found a way to get a clean view of the disks surrounding black holes by using a polarizing filter in the infrared. This technique works in particular when the region immediately surrounding the black hole emits a small amount of scattered light. Since scattered light is polarized, astronomers can use a filter that works like polarized sunglasses on large telescopes to detect this small amount of scattered light and measure it with unprecedented accuracy. Scientists have theorized these luminous disks existed around black holes, but until now have not been able to observe them.

Hubble observes "thin ribbon" of 1,000-yr-old supernova remnant

Hubble Enters 100,000th Orbit

NASA's Hubble Space Telescope completed its 100,000th orbit of Earth on the morning of August 11. In commemoration of this event in its 18th year of exploration and discovery, scientists at the Space Telescope Science Institute in Baltimore, Md., aimed Hubble at a dazzling region of celestial birth and renewal. Hubble peered into a small portion of this nebula near the star cluster NGC 2074.

Hubble celebrates 100,000

in April of 1990, the Hubble Space Telescope has been without equals for bringing the wonders of the cosmos into the homes of people around the world. Yesterday, August 11th, 2008 the Hubble Telescope surpassed a lofty milestone; it completed its 100,000th orbit of the Earth. To celebrate this milestone, Hubble sent back a spectacular image of a small, active portion of the Tarantula nebula.

Hubble Does Independence Day With Stars and Stripe

Back in 1006 A.D, observers from Africa to Europe to the Far East witnessed and recorded the arrival of light from what is now called SN 1006, a tremendous supernova explosion caused by the final death throes of a white dwarf star nearly 7,000 light-years away. One Egyptian astronomer recorded the object was 2 - 3 times as large as the disc of Venus and about one quarter the brightness of the moon. The supernova was probably the brightest star ever seen by humans, visible even during the day for weeks, and it remained visible to the naked eye for at least two and a half years before fading away. Remnants of this supernova are still visible to telescopes, and the Hubble Space Telescope captured this close-up a filament of the shock wave of the explosion, still reverberating through space, seen here against the grid of background stars.

JPL Camera Marks Hubble's 100,000th Orbit

In commemoration of NASA's Hubble Space Telescope completing its 100,000th orbit, scientists used the JPL-built Wide Field and Planetary Camera 2 to take a snapshot of a dazzling region of a nebula 170,000 light-years away (near the Tarantula nebula). Hubble peered into a small portion of the nebula near the star cluster NGC 2074 (upper, left). The region, a firestorm of raw stellar creation, is one of the most active star-forming regions in our Local Group of galaxies. Scientists speculate it was perhaps triggered by a nearby supernova explosion.

'Slow' Light To Speed Up the Net

JPawlak writes "Researchers believe that it may be possible to increase the speed of the Internet by slowing down certain parts of it by using metamaterials. Metamaterials could be used to replace the bulky and slow electronics that route Internet information, allowing for faster Internet speeds. As data nears its destination, the frequencies must be separated. The light must then be converted into electrical signals, which are stored, routed, and converted back into optical signals. The conversion not only adds significant cost and complexity to the process, but slows down the transmission as well. However, if the light signals could be slowed during the switching process, they would not need to be converted into an electrical signal. 'The ability to slow the light could be a tremendous force for telecoms that is sure to enhance speed an

The observatory was designed to have a long life span of 15 years. The HST is a co-operative programme of the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA). The aim of the observatory is to operate a long-lived space-based observatory for the benefit of the international astronomical community.

Death Note DVD 5

L and the police have kept Light and Misa in confinement for fifty days, but Kira has not stopped killing, and they have not confessed. They pass a test devised by L that requires Light's father to put his own life on the line and are released. Even so, L does not trust them and places them under twenty-four hour surveillance. Light, he keeps handcuffed to him at all times. Though they have lost the support of law enforcement, the investigative team led by L is soon able to link Kira to the Yotsuba Group. Matsuda, driven by a bout of foolish initiative, sneaks into Yotsuba's Headquarters and discovers a secret cabal of businessmen who appear to be controlling the Kira murders. Light then gets in contact with one of their number in order to convince him to turn Kira in.

Peacock feathers and butterfly wings inspire bio-templated nanotechnology materials

(Nanowerk Spotlight) Photonic crystals – also known as photonic band gap material – are similar to semiconductors, only that the electrons are replaced by photons (i.e. light). By creating periodic structures out of materials with contrast in their dielectric constants, it becomes possible to guide the flow of light through the photonic crystals in a way similar to how electrons are directed through doped regions of semiconductors. The photonic band gap (that forbids propagation of a certain frequency range of light) gives rise to distinct optical phenomena and enables one to control light with amazing facility and produce effects that are impossible with conventional optics.
