new type of AGN
Japanese and NASA satellites unveil new type of active galaxy
(Jul 31, 2007)


An international team of astronomers using NASA's Swift satellite and the Japanese/US Suzaku X-ray observatory has discovered a new class of active galactic nuclei (AGN). By now, youd think that astronomers would have found all the different classes of AGN – extraordinarily energetic cores of galaxies powered by accreting supermassive black holes. But by using Swift and Suzaku, the team has discovered that a relatively common class of AGN has escaped detection – until now.

CCAT
Huge telescope to probe galactic origins
(Jul 30, 2007)


A giant telescope planned to be built in Chile is expected to find hundreds of thousands of developing galaxies in the early universe. The Cornell Caltech Atacama Telescope (CCAT) will observe at submillimetre wavelengths, which make up part of the microwave portion of the electromagnetic spectrum. With its 25-metre dish, the $100 million telescope will be the largest in the world for submillimetre astronomy when it is finished in 2013.

GOCE
'Space arrow' to map Earth's tug
(Jul 29, 2007)


A satellite that can measure tiny variations in the Earth's gravity field will be one of Europe's most challenging space missions to date. GOCE, due for launch next year, looks like a spyplane from a movie. Its arrow shape, fins, and electric engine help keep the satellite stable as it flies through the wisps of air still present at an altitude of 260km.

Zachary Quinto
Heroes villain lands Spock role
(Jul 27, 2007)


Heroes villain Zachary Quinto is to star as Mr Spock in the latest Star Trek film. The Paramount Pictures film, whose working title is Star Trek XI, revolves around the first encounters between a young Spock and James T Kirk. Leonard Nimoy, who played the original Mr Spock, will play an older version of the character in the new film.

International Space Station
NASA scandals overshadow launch
(Jul 27, 2007)


Reports of sabotage and intoxicated astronauts upstaged the US space agency's announcement on Thursday that the teacher tapped 21 years ago to fly in space would finally blast off aboard a space shuttle on 7 August. Instead of discussing teacher-astronaut Barbara Morgan and the upcoming construction mission to the International Space Station (ISS), NASA managers were left to fence with reporters at the Kennedy Space Center in Florida.

Taurus molecular cloud
Organic compound found in the stars
(Jul 26, 2007)


Astronomers have found the largest negatively charged molecule so far seen in interstellar space. The molecule is a chain of eight carbons and a single hydrogen called the octatetraynyl anion (C8H). Two teams of scientists have spotted it near a dying star and in a cloud of cold gas. [Image: Taurus Molecular Cloud]

HD 98800
Quadruple star system may host a planet
(Jul 25, 2007)


Planets may be present in a quadruple star system 150 light years from Earth, according to Spitzer Space Telescope observations. The system, called HD 98800, consists of two pairs of stars in which the partners in each pair orbit one another closely. The pairs themselves travel around each other on a very elongated path.

International Space Station
Space station's future threatened, expert warns
(Jul 25, 2007)


NASA and its international partners may be hard-pressed to keep the space station alive after the planned retirement of the space shuttle in 2010, a US congressional committee was told today. The US House of Representatives Committee on Science and Technology's Subcommittee on Space and Aeronautics held a hearing on the status of the space shuttle and the International Space Station (ISS) on Tuesday in Washington, DC.

hypervelocity star
Is a second black hole lurking in the Milky Way's heart?
(Jul 24, 2007)


Is a second black hole lurking in the heart of the Milky Way? The evidence to date is inconclusive, but astronomers say a relatively simple test could settle the matter: look for a pair of stars fleeing the galaxy at break-neck speed. Astronomers believe there is a colossal black hole – weighing about 3.6 million times the Sun's mass – at the centre of the Milky Way. But some contend there is also a second black hole there that weighs 1000 to 10,000 Suns.

supernova remnant N132D
Spitzer searches for the origins of life on Earth
(Jul 23, 2007)


Astronomers suspect the early Earth was a very harsh place. Many scientists believe that life's starting materials must have been very resilient to have survived this tumultuous environment. Now, NASA's Spitzer Space Telescope has learned, for the first time, that organic molecules believed to be among life's building blocks, called polycyclic aromatic hydrocarbons (PAHs), can survive another type of harsh setting, an explosion called a supernova.
