Comet Chury is much younger than previously thought

Science Daily: Comets and Asteroids -

Based on computer simulations, astrophysicists conclude that the comet Chury did not obtain its duck-like form during the formation of our solar system 4.5 billion years ago. Although it does contain primordial material, they are able to show that the comet in its present form is hardly more than a billion years old.

Election Day 2016

NASA: Image of the Day -

Thanks to a bill passed by Texas legislators that put in place technical voting procedure for astronauts, they have the ability to vote from space through specially designed absentee ballots. To preserve the integrity of the secret vote, the ballot is encrypted and only accessible by the astronaut and the county clerk responsible for casting it.

NASA's MMS breaks Guinness World Record

Science Daily: Comets and Asteroids -

NASA's Magnetospheric Multiscale mission, or MMS, is breaking records. MMS now holds the Guinness World Record for highest altitude fix of a GPS signal. Operating in a highly elliptical orbit around Earth, the MMS satellites set the record at 43,500 miles above the surface. The four MMS spacecraft incorporate GPS measurements into their precise tracking systems, which require extremely sensitive position and orbit calculations to guide tight flying formations.

Detour via gravitational lens makes distant galaxy visible

Science Daily: Comets and Asteroids -

Never before have astrophysicists measured light of such high energy from a celestial object so far away. Around 7 billion years ago, a huge explosion occurred at the black hole in the center of a galaxy. This was followed by a burst of high-intensity gamma rays. A number of telescopes have succeeded in capturing this light. An added bonus: it was thus possible to reconfirm Einstein's General Theory of Relativity, as the light rays encountered a less distant galaxy en route to Earth -- and were deflected by this so-called gravitational lens.

NASA Announces Media Briefing on New Hurricane Mission

NASA: Earth News -

NASA will hold a media briefing at 1 p.m. EST Thursday, Nov. 10, to discuss the upcoming Cyclone Global Navigation Satellite System (CYGNSS) mission, a constellation of eight microsatellites that will gather never-before-seen details on the formation and intensity of tropical cyclones and hurricanes.

Crack discovered in Earth's magnetic shield

Science Daily: Comets and Asteroids -

The GRAPES-3 muon telescope recorded a burst of galactic cosmic rays of about 20 GeV, on 22 June 2015 lasting for two hours. The burst occurred when a giant cloud of plasma ejected from the solar corona, and moving with a speed of about 2.5 million kilometers per hour struck our planet, causing a severe compression of Earth's magnetosphere from 11 to 4 times the radius of Earth. It triggered a severe geomagnetic storm that generated aurora borealis, and radio signal blackouts in many high latitude countries.
