"The theme of this blog is not only and obviously space, but in particular places in space that a person might theoretically be able to one day visit. So for the most part, nebula, galaxies and the like are not a part of this forum. I tend to focus on “terrestrial” places or places that host such places. I suppose I would like to find out more about these places that we may one day inhabit or simply visit."

The zodiac calendar has been corrected based on the original Babylonian setup. "When [astrologers] say that the sun is in Pisces, it's really not in Pisces," said Parke Kunkle, a board member of the Minnesota Planetarium Society. [more inside]

Yesterday there was a partial solar eclipse over most of Europe and northwestern Asia. There were a lot of great pictures, but the most spectacular may have been the solar transit of the International Space Station during the partial eclipse, taken by French astrophotographer, Thierry Legault. Bad Astronomy has more on why he chose the Sultanate of Oman, and how he captured a picture that was possible for less than a second. Bad Astronomy also covered his picture of the lunar transit of ISS, captured December 21, 2010.
Cosmic Journeys is a documentary series on various astronomical and space-related subjects, e.g. supermassive black holes, Apollo 12, whether the universe is infinite and many more. The creators, SpaceRip have a lot of other, shorter videos online as well. They are indexed here. Most, if not all, of the videos are available in HD.

Planet Hunters lets users comb through data from the Kepler mission in search of exoplanets. [via Bad Astronomy]
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.
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 first 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)
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.
This may just be the most peaceful, beautiful 5-1/2 minutes of your entire day: An audio slideshow look at some of the winning images, guided by one of the judges, of the Royal Observatory in Greenwich's 2010 Astronomy Photographer of the Year competition. Interested in "giving it a go"? Here are some guides to photographing different aspects of the night sky.

"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.

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.

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.
"Heritage Sites of Astronomy and Archaeoastronomy in the Context of the World Heritage Convention" (also available here) is a collaborative study by the IAU Working Group on Astronomy and World Heritage and the International Council on Monuments and Sites (ICOMOS). The study has been endorsed by the UNESCO World Heritage Committee, at its 34th session in Brasília, Brazil, marking the first time a study in scientific heritage has been so endorsed. [more inside]
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 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]

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).
Early this morning, local time, two amateur astronomers independently captured images of something colliding with Jupiter. Anthony Wesley (cache) in Broken Hill, Australia noticed it first.
