At the end of October a Soyuz will be launched from Europe's Space Port in French Guiana for the first time, carrying into orbit the first pair of so-called IOV satellites. IOV stand for In-Orbit Validation: it's the phase when the Galileo system will be assessed through tests using the operations of two experimental satellites (GIOVE A and B already on orbit) and a mini constellation of four operational satellites and their related ground infrastructure. These first 2 Galileo satellites will be sent to the first orbital plane on Medium earth Orbit, followed by another 2 in the second orbital plane next year.

Astronauts’ jobs sometimes weigh heavy on them: crews returning from space briefly endure ‘g-loading’ more than four times Earth normal. Scientists interested in hypergravity need to create it for minutes, days or even weeks at a time. Fortunately, ESA’s Large Diameter Centrifuge does just that. (read more)

Astronomers have used ESO’s Very Large Telescope to image a colossal star that belongs to one of the rarest classes of stars in the Universe, the yellow hypergiants. The new picture is the best ever taken of a star in this class and shows for the first time a huge dusty double shell surrounding the central hypergiant. The star and its shells resemble an egg white around a yolky centre, leading the astronomers to nickname the object the Fried Egg Nebula. (learn more)

First planet candidates discovered by "Planet Hunters"

Source: Planet Hunters

Thanks to all collaborators hard work at planethunters.org - a first paper was submitted to an astronomical journal, and it is now nearly through the referee process. The findings can be seen in detail in the paper titled "Planet Hunters: Two Planet Candidates Discovered by the Public using the Kepler Public Archive Data" which you can read at: http://arxiv.org/abs/1109.4621

After careful analysis and follow-up observations with the Keck telescope in Hawaii, the Planet Hunters team sent the top 10 candidates found from your classifications of the Quarter 1 data to the Kepler team. With their help, it has been determined that two of the ten met their criteria for being classified as planet candidates.

If you're lucky enough to be one of the people who marked a transit, then your name is in the paper - the rest of you will find yourselves on the extended author list at http://planethunters.org/authors.

In other news, the Kepler team announced (http://www.nasa.gov/mission_pages/kepler/news/keplerm-Q3release.html) that the next public release of data has been moved up from June 2012 to right now. Quarter 3 is an extra 90 days of light curves, nearly doubling the time baseline we have available for all the Kepler stars - meaning you can find even longer period planets hidden in the data. We're already working on getting this data to you, but in the mean time, there’s still lots of Quarter 2 data left to search through.

Planet Hunters is already producing fantastic results, and there is no doubt that with each new round of data, there will be more discoveries to come. Come and help the hunt for planets today: http://www.planethunters.org

Material particles travel faster than the speed of light (!?)

The OPERA experiment, which observes a neutrino beam from CERN 730 km away at Italy’s INFN Gran Sasso Laboratory, will present new results in a seminar at CERN today.

The OPERA result is based on the observation of over 15000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature’s cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. This is why the OPERA collaboration has decided to open the result to broader scrutiny. (read more)

A unique science project designed to sow the excitement of scientific discovery in students is sprouting this week aboard the International Space Station. The Plants in Space project will allow students and teachers to examine root growth in microgravity and compare the results with those from plants used in their own ground-based experiments.

The National Space Biomedical Research Institute (NSBRI) is funding the project. It began Tuesday, Sept. 20, when space station astronauts planted Brassica rapa seeds during the first of four scheduled five-day trials. The project's primary scientific goal is to investigate the influence of light on root orientation. (learn more)

NASA is releasing the initial version of a Global Exploration Roadmap (GER) developed by the International Space Exploration Coordination Group. This roadmap is the culmination of work by 12 space agencies, including NASA,  during the past year to advance coordinated space exploration.

The GER begins with the International Space Station and expands human presence throughout the solar system,  leading ultimately to crewed missions to explore the surface of Mars.

The roadmap identifies two potential pathways: "Asteroid Next" and "Moon Next." Each pathway represents a mission scenario that covers a 25-year period with a logical sequence of robotic and human missions. Both pathways were deemed practical approaches to address common high-level exploration goals developed by the participating agencies, recognizing that individual preferences among them may vary.

WISE raises doubt about asteroid family believed responsible for dinosaur extinction

Observations from NASA's Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping the case open on one of Earth's greatest mysteries.

While scientists are confident a large asteroid crashed into Earth approximately 65 million years ago, leading to the extinction of dinosaurs and some other lifeforms on our planet, they do not know exactly where the asteroid came from or how it made its way to Earth.

A 2007 study using visible-light data from ground-based telescopes first suggested the remnant of a huge asteroid, known as Baptistina, as a possible suspect. According to that theory, Baptistina crashed into another asteroid in the main belt between Mars and Jupiter about 160 million years ago. The collision sent shattered pieces as big as mountains flying. One of those pieces was believed to have impacted Earth, causing the dinosaurs' extinction.

Since this scenario was first proposed, evidence developed that the so-called Baptistina family of asteroids was not the responsible party. With the new infrared observations from WISE, astronomers say Baptistina may finally be ruled out. (read more)
