Black Hole Thursdays.

Thursday, July 24, 2008

Astronomers have for the first time developed a technique to view rapidly spinning disks of gas found near black holes.Their observations allowed them to confirm the that the electromagnetic spectra of these accretion disks match what astronomers have long predicted, giving a boost of hard evidence to current quasar formation theory.The team of researchers gazed into the night on Mauna Kea in Hawaii, looking through the United Kingdom Infrared Telescope. They were able to measure the spectrum of.. Read more »

Another Side of Phobos

Wednesday, July 23, 2008

Today the camera eyes of the European Space Agency's Mars Express spacecraft will scrutinize the oddly shaped and pockmarked Phobos, as it makes its closest ever pass by the largest of Martian moons, gliding a mere 60 miles above its surface.The spacecraft will use all of its high-tech tricks to perform a thorough examination, taking 3-D images, mapping with a high-resolution camera, making precise measurements of the Phobos' mass and composition, and unleashing its subsurface probing radar ..

What do a Dwarf Planet and a Polynesian God Have in Common?

Wednesday, July 23, 2008

They both share the same name: Makemake ( say it with me, MAH-kay, MAH-kay). The planet naming authority of the International Astronomical Union recently decided on the name, which comes from the Polynesian god of fertility and and creator of humanity.The dwarf planet, is a member of the newly created plutoid subclass, where it joins Pluto and Eris. Like its plutoid brethren, Makemake is far off from the sun, lying beyond Neptune... Read more »

And Then There Was Light...Emitting Diodes

Tuesday, July 22, 2008

They've been around since the 1960s (mostly in traffic signals), but Light Emitting Diodes(LEDs) are lighting up the future.I could rave about all the neat characteristics these luminous materials have, but only two are really important: LED lights only need to be replaced every 15 years, and they could potentially reduce the amount of electricity we consume by 10 percent, if used widely.What more could one want in a lighting source? Unfortunately, there is a "dark" side to LEDs. They are painst.. Read more »

Large Hadron Collider: Colder Than Deep Space

Monday, July 21, 2008

Everyone's favorite particle smasher, the Large Hadron Collider (LHC) has almost reached 1.9 Kelvin (-465F), colder than deep space. Never before has a physics experiment so enormous and complex been operated at such extremely low temperatures.It contains 7,000 magnets that will be maintained at colder than space temperatures using liquid helium, in order to make them superconducting. The magnets are arranged in a ring that runs through the underground tunnel.Cooling the Collider is a process th.. Read more »
