Will Mars be rocked by a massive comet in 2014? Maybe a little. Maybe a lot. A comet will definitely pass close to the Red Planet on October 19, 2014. [more inside]
Finnish astrophotographer J-P Metsävainio has created some stunning 3D animations (more at his blog) of far-flung nebula. Phil Plait first pointed to them back in October. Today, there's a post on the Smithsonian Magazine's website about them.
NASA has announced that the latest Kepler data dump contains 1,091 extrasolar planet candidates, with 196 Earth-sized planets among them. The data shows "a clear trend toward smaller planets at longer orbital periods is evident with each new catalog release. This suggests that Earth-size planets in the habitable zone are forthcoming if, indeed, such planets are abundant." Total Kepler candidates as of February 27, 2012: 2,321. [more inside]
Astronomers using data from NASA's Kepler mission have discovered the three smallest planets yet detected orbiting a star beyond our sun. The planets orbit a single star, called KOI-961, and are 0.78, 0.73 and 0.57 times the radius of Earth. The smallest is about the size of Mars.
Saturday August 27 Bill Nye dedicated a solar noon clock he designed. The clock is embedded in the facade of Rhodes Hall. At Solar Noon, when the Sun culminates, that is, reaches its highest point in the sky, the sun-shaped feature will light up. It is the marrying of mechanical and electrical engineering with astronomy. What could be better?
NASA's Juno spacecraft launched this morning and is en route to Jupiter (launch video). Equipped with microwave, ultraviolet, infrared, and visible light detectors Juno will investigate the origins, atmosphere, and magnetosphere of the Solar System's largest planets over one year beginning with its arrival in 2016. Using its awesome solar-powered technology Juno will show Jupiter's magnetic field in detail never before seen. We probably won't hear much from Juno again until 2013, when it makes a fly-by of Earth. You can follow Juno on Twitter, so if it types out its scream, someone will hear it. Also
screaming traveling aboard Juno are three very special LEGO mini-figurines.
The International Academy of Astronautics is holding the Planetary Defense Conference: Protecting Earth from Asteroids May 9-12, 2011. in Bucharest, Romania [more inside]
On February 14 NASA's Stardust-NExT mission revisited the comet Tempel 1. Tempel 1 was first visited by NASA's Deep Impact, which smashed into the comet back in July 2005. [more inside]
NASAs Kepler mission has discovered over 1,100 extrasolar planet candidates. Including, "68 Earth-sized, 288 super-Earth-sized, 662 Neptune-sized, and 165 Jupiter-sized planets". 54 are found in their star's habitable zone, with five of those considered "near-Earth sized" [more inside]
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.
"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]
The Planetary Society's Emily Lakdawalla has prepared a scale image of every asteroid and comet ever visited by a spacecraft. [more inside]
The European Space Agency's Rosetta craft has returned stunning images of the asteroid 21 Lutetia, including this one which couples Lutetia with a member of our planetary family. [more inside]
Scientists at NASA will announce the first findings from the Kepler mission next month. The results have caught scientists off-guard but they aren't giving any hints as to what mission co-investigator David Latham "was not prescient enough to anticipate". [more inside]
As Earth continues its pass through the debris field left by periodic Comet Swift-Tuttle on August 11 and 12, the annual Perseid Meteor Shower could deliver a double peak and a brief period of up to 200 meteors per hour. [more inside]
