Measuring Stellar Gravity
2013-08-23 08:58:22

[ Watch The Video: Star Flickering Discovery ] John P. Millis, PhD for redOrbit.com - Your Universe Online A star’s gravitational strength is key in understanding and modeling other properties of a particular star, to say nothing of understanding the planets that orbit around it. But making accurate measurements of a star’s surface gravity is difficult, and measurements are often only good to within about a 50% estimation of the actual value, sometimes worse. Now, however,...

Gaia Arrived In French Guiana Today
2013-08-23 07:44:51

ESA ESA’s billion-star surveyor, Gaia, departed yesterday evening from Toulouse and arrived early this morning in French Guiana. Gaia will be launched later this year from Europe’s Spaceport in Kourou on a five-year mission to map the stars of the Milky Way with unprecedented precision. Built by Astrium in Toulouse, the Gaia spacecraft took off on board an Antonov 124 heavy-lift aircraft at 20.00 yesterday from Toulouse airport with the destination of Cayenne, the capital of French...

Sharpest Photos Ever of the Night Sky
2013-08-22 04:43:24

redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the University of Arizona, the Arcetri Observatory in Italy and the Carnegie Observatory have used a new type of telescope camera to capture the highest-resolution images of the night sky ever – answering some longstanding questions about planetary formation in the process. The technology, which has been in development at Arizona observatories for over two decades, was recently deployed in the high desert of...

Fermi Begins Extended Mission
2013-08-22 04:19:34

[ Watch the Video: Fermi at Five Years ] redOrbit Staff & Wire Reports - Your Universe Online Having successfully completed its five-year primary mission, NASA’s Fermi Gamma-ray Space Telescope entered the extended phase of its mission earlier this month – a deeper analysis of the high-energy cosmos that the US space agency hopes will continue through the year 2018. Fermi, which began the extended phase of its mission on August 11, has given astronomers an increasingly...

Sounding Rocket Getting Ready To Study Active Regions On The Sun
2013-08-03 07:59:17

NASA At NASA's White Sands Test Facility in Las Cruces, N.M., a sounding rocket is being readied for flight. Due to launch on Aug. 8, 2013, the VERIS rocket, short for Very high Resolution Imaging Spectrometer, will launch for a 15-minute trip carrying an instrument that can measure properties of the structures in the sun's upper atmosphere down to 145 miles across, some eight times clearer than any similar telescope currently in space. When it comes to observing the sun, different...

New Explorer Mission Chooses The 'Goldilocks Orbit'
2013-08-01 08:05:06

NASA Principal Investigator George Ricker likes to call it the "Goldilocks orbit" -- it's not too close to Earth and her Moon, and it's not too far. In fact, it's just right. And as a result of this never-before-used orbit -- advanced and fine-tuned by NASA engineers and other members of the Transiting Exoplanet Survey Satellite (TESS) team -- the Explorer mission led by Ricker will be perfectly positioned to map the locations of more than 500 transiting exoplanets, extrasolar planets...
