Space Shack

Skylab, NASA's budget space station, launched 40 years ago today. Designed as an orbiting optical laboratory, she served as a cold war weapon, underwent an historic salvage job, and was the site of America's first space mutiny before landing hard in Australia while waiting for the Space Shuttle to be invented.

Star gazing girls of Georgian England

An intriguing essay on how young women in Georgian England were able to do science by hiding in the pursuits of the domestic arts.
"Women didn’t find it easy to participate in late eighteenth century science. Experimentation and discovery were not easily compatible with the ideals of domestic femininity – but there were women who rejected these social expectations and became active and renowned."

Destroyer Gods and Sons-of-Bitches

In the telling it has the contours of a creation myth: At a time of great evil and great terror, a small group of scientists, among the world’s greatest minds, secluded themselves in the desert. In secrecy and silence they toiled at their Promethean task. They sought the ultimate weapon, one of such great power as to end not just their war, but all war. They hoped their work would salvage the future. They feared it could end everything. - Prometheus in the desert: from atom bombs to radio astronomy, New Mexico's scientific legacy

What do you mean you've never been to Alpha Centauri? Oh, for heavens sake mankind, it's only four light years away, you know.

A planet with about the same mass as Earth has been discovered in orbit around Alpha Centauri B, a star in the Alpha Centauri triple star system - the solar system's closest neighbor, a mere 4.3 light years away. Alpha Centauri B is very similar to the Sun, and this marks the first planet with a mass similar to Earth ever found around a Sun-like star. However, the planet is orbiting at a distance of about six million kilometers, much closer than Mercury is to the Sun in the Solar System, so temperatures above 400 degrees Celsius may make vacationing there unpalatable even for the most dedicated beach-goer. However, lead paper author Xavier Dumusque called it "a major step towards the detection of a twin Earth in the immediate vicinity of the Sun."

13 billion light-years from home

eXtreme Deep Field (1.4 MB JPG) is the deepest-ever view of the universe - a new assemblage of 10 years of Hubble Space Telescope photographs focused on a small area at the center of the original Ultra Deep Field. With a cumulative exposure time of 2 million seconds, XDF shows approximately 5,500 galaxies - some of them 10 billion times too faint to be seen with the naked eye.

What came before Pangea? What comes next?

A history of the world. As seen from space. Over a really long stretch of time. If the Earth is about 4.5 billion years old, and Pangea split up only about 200 million years ago, what happened before then? I never knew that geologists could reconstruct the continents' movements from before Pangea. Not only that, but they can give us a preview of what comes next. Here's three possible ways the continents might be joined in 250 million years. In the big picture, researchers from U.C. Lancashire have just finished a model of the way the Milky Way Galaxy formed.

For once, clouds are a good thing

One of the neater aspects of astronomy is that amateurs often make significant contributions to the field. A few nights ago Wayne Jaeschke found a strange cloud feature in his Mars images. He posted his findings to the site Cloudy Nights. It created a bit of a buzz there, as well as the wider media, (even MSNBC!). It has also piqued the interest of the pros. Researchers working with the Mars Thermal Emission Imaging System onboard the Mars Odyssey spacecraft and the Mars Color Imager onboard the Mars Reconnaissance Observer are looking over their data to try to figure out exactly what it is they're seeing.

Visualization of the dark matter in 1/1000 of the gigantic Bolshoi cosmological simulation, zooming in on a region centered on the dark matter halo of a very large cluster of galaxies. ... The Bolshoi simulation is the most accurate cosmological simulation of the evolution of the large-scale structure of the universe yet made (“bolshoi” is the Russian word for “great” or “grand”).

Four billion years ago a star left its legacy as it met its physically inevitable demise

A gamma ray burst nicknamed GRB 110328A (i.e. detected 3/28/2011) appears to be the legacy of a star being torn apart by a supermassive black hole, leaving a peak brightness one trillion times the sun's brightness as it met its ancient inevitable end.

Planets made of diamond and graphite?

A hot carbon-rich gas giant exoplanet, WASP-12b, has been discovered. As the lead author of the paper being published today, Nikku Madhusudhan, says: ""This planet reveals the astounding diversity of worlds out there". In particular, the discovery supports theories that there are likely to be planets made of diamond and graphite out there.

What the pangeaists don't want you to know

Don't continue fooling yourself. The earth is growing and expanding rapidly. Despite plate tectonics' popular acceptance in the 60s, Samuel Warren Carey, the father of modern expansion tectonics, was publicly promoting his theories of an expanded earth as late as 1981. One of the theory's most prominent modern spokesmen is comics artist Neal Adams, who has created a number of informative videos about a new model of the universe that even manages to explain why the dinosaurs died out.

WISE: Beyond Hubble

On July 17th, NASA's Wide-field Infrared Survey Explorer (WISE) satellite completed its first survey of the entire sky viewable from Earth. After just seven months in orbit, WISE -- a precursor to the planned James Webb Space Telescope -- has returned more than a million images that provide a close look at celestial objects ranging from distant galaxies to asteroids. The first release of WISE data, covering about 80 percent of the sky, will be delivered to the astronomical community in May of next year, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries (containing just a small selection of images): 1, 2, 3, 4.

Planck unveils the Universe

Planck telescope reveals ancient cosmic light. "The picture is the first full-sky image from Europe's Planck telescope which was sent into space last year to survey the oldest light in the cosmos. It took the 600m-euro observatory just over six months to assemble the map. It shows what is visible beyond the Earth to instruments that are sensitive to light at very long wavelengths - much longer than what we can sense with our eyes." [more inside]

Water is likely to be widespread in the moon’s interior

The Carnegie Institution for Science reports "a much higher water content in the Moon’s interior than previous studies." For decades, the moon's water content was estimated at less than 1 part per billion; the new estimates range from 64 ppb to 5 parts per million. A scientist at Washington University said, "We can now finally begin to consider the implications—and the origin—of water in the interior of the Moon.” There's more at NASA and the BBC, and the full paper is available at PNAS (PDF).

The Sun Is a Miasma of Incandescent Plasma

...the lyrics to that last song were basically taken from an encyclopedia written in the 50s, and since the 50s, some remarkable things have happened...
In 1959, a number of songs about science were released on an album called Space Songs. One of these was later covered by the band They Might Be Giants: Why Does The Sun Shine? (The Sun Is A Mass of Incandescent Gas). Only one problem: it isn't--the song was based on an incorrect text from 1951. So they wrote an answer song to themselves: Why Does The Sun Really Shine? (The Sun Is a Miasma of Incandescent Plasma). Bonus link: see for yourself! (previously)
