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.

"A novel metric of habitability"

Amid news of new extrasolar planet discoveries, including a system with a possible 7 planets, Greg Laughlin and Sam Arbesman have released a paper that will be published next month in the open-access journal PLoS One. "A Scientometric Prediction of the Discovery of the First Potentially Habitable Planet with a Mass Similar to Earth" (pdf of full paper) boldly predicts that: "the fi rst potentially habitable planet will be discovered, in this case, as early as May 2011, and likely by the end of 2013." NASA's Kepler mission is set to release data on hundreds of candidate planets early next year. The mission has discovered 7 so far. (Pre-vio-usly)

Before the heliosheath

Emily Lakdawalla has published the first 42 of 99 Voyager Mission Status Bulletins (thanks to space fan Tom Faber). Before the days of the internet, updates on space missions were distributed via newsletter. From 1977-1990 NASA published these Voyager newsletters to update scientists and enthusiasts. Both Voyager I and Voyager II are still out there, hurtling toward the stars. Voyager I and II weekly status updates from 1995-present are currently available online. Lakdawalla will be publishing the rest of the bulletins after she indexes them.

What am I myself but one of your meteors?

"A moment, a moment long, it sail’d its balls of unearthly light over our heads, Then departed, dropt in the night, and was gone" Walt Whitman wrote these words in the poem Year of Meteors, 1859 ’60. Not until this year did a team of forensic astronomers at Texas State University, with the assistance of a painting from the Hudson River School, figure out what he was really talking about.

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.

I began to doubt the faith of my own eyes.

Astronomers using ESO’s Very Large Telescope have for the first time obtained a three-dimensional view of the distribution of the innermost material expelled by a recently exploded star. The original blast was not only powerful, according to the new results, it was also more concentrated in one particular direction. This is a strong indication that the supernova must have been very turbulent, supporting the most recent computer models. Super-cool zooming video.

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).

That's Science!

People have been upset about Pluto's demotion for some time now. (While classical music fans have just had a love/hate relationship with this whole process.) But astronomical hate mail has never been as cute as the missives Neil deGrasse Tyson has received over the years from tots upset at poor Pluto's ouster.

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)

Saturn's Rings to Disappear Tonight

August 11th marks the coming of Spring to Saturn's northern hemisphere, when the 170,000 miles wide rings turn edge-on to the sun and reflect almost no sunlight. The rings are only some 10 meters (30 feet) thick and made of mud and ice. As Saturn shifts towards its once every 15 year equinox, out-of-plane structures will cast long shadows across the rings' broad expanse, making them easy to detect (previously). Though you can't see the rings with the unaided eye, professional and amateur astronomers have captured the gas giant in its transition towards the equinox.
