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."

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.

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."

One of my favorite blogs
happens to be local to me. Eric Berger, the Houston Chronicle's "SciGuy" usually reports on the weather
. But he also posts entertaining and serious stuff as well. [more inside]

Where's Tyche, the 10th 9th planet? Getting the full story.
John Matese and Daniel Whitmire of the University of Louisiana at Lafayette recently made the news when they announced the possible discovery of a gas giant planet they named Tyche
in the Oort Cloud, at the extreme edge of the Solar System (previously
). Now ars electronica breaks down the evidence behind the announcement, what can be done to confirm or disprove its existence & how long it could take.

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
. 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)
. Videos and Animations: 1

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.”

and the BBC

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.
