Could Comet ISON possibly still be alive? The latest high-resolution images available from the STEREO spacecraft are still showing some remains of the comet, although each day seems to show less and less activity. “If anything of ISON’s nucleus is left, it’s an inactive husk of a nucleus now,” Karl Battams from the Comet ISON Observing Campaign told Universe Today. “The comet remnant is fading fast in the STEREO data. — Is Anything Left of ISON? Spacecraft Continue to Monitor Comet’s Remains
Gravity. The average person probably doesn’t think about it on a daily basis, but yet gravity affects our every move. Because of gravity, we fall down (not up), objects crash to the floor, and we don’t go flying off into space when we jump in the air. The old adage, “everything that goes up must come down” makes perfect sense to everyone because from the day we are born, we are seemingly bound to Earth’s surface due to this all-pervasive invisible force. — Where Does Gravity Come From?
Quantum physics is a fascinating yet complicated subject to understand, and one of the things that freaks out physics students every is the concept of entanglement. That occurs when physicists attempt to measure the state of a particle and that affects the state of another particle instantly. (In reality, the particles are in multiple states — spinning in multiple directions, for example — and can only be said to be in one state or another when they are measured.) — Could Particle ‘Spooky Action’ Define The Nature Of Gravity?
A raging hurricane is creating a “suck zone” at Saturn’s north pole. The handy Cassini spacecraft recently captured a bunch of images of the six-sided jet stream surrounding the storm, which mission managers then put together into an awesome animation showing the wind currents shifting. (You can see the animation below the jump.) — Saturn’s Mysterious Hexagon Behaves Like Earth’s Ozone Hole
CAPE CANAVERAL AIR FORCE STATION, FL – The flawless blastoff of SpaceX’s next generation Falcon 9 rocket on Tuesday Dec. 3 put on a spectacular sky show along the Florida Space Coast that was both beautiful and unforgettable – besides being truly historic as the firms first ever delivery of a commercial space satellite to the lucrative market of geostationary orbit. — SpaceX SES-8 Flawlessly Beautiful Dec. 3 Launch – Photo and Video Gallery
If you live in the southern hemisphere, the southern sky constellation of Centaurus may look a little different to you tonight, as a bright nova has been identified in the region early this week. — A Naked Eye Nova Erupts in Centaurus
China successfully launched its first ever lunar rover bound for the Moon’s surface aboard a Long March rocket today at 1:30 a.m. Beijing local time, Dec. 2, 2013 (12:30 p.m. EST, Dec. 1) from the Xichang Satellite Launch Center in southwest China. — Spectacular Liftoff Thrusts China’s First Rover ‘Yutu’ to the Moon
A team of European astronomers has discovered a second solar system, the closest parallel to our own solar system yet found. It includes seven exoplanets orbiting a star with the small rocky planets close to their host star and the gas giant planets further away. The system was hidden within the wealth of data from the Kepler Space Telescope. — Second Solar System Like Ours Discovered
In just one minute, you can watch the Herschel space telescope painting the sky blue, green and yellow! The colors in this new video represent four years of observations from the European Space Agency telescope, which was active between 2009 and 2013. — Speedy Science: Here’s Four Years Of Herschel Telescope Work In A Short Video
The maiden flight of the Next Generation commercial SpaceX Falcon 9 rocket from the firms Cape Canaveral launch facility is set to soar to space on Monday afternoon, Nov. 25 on a ground breaking mission that will be most difficult ever. — Maiden Next Gen SpaceX Falcon 9 launch from Cape Canaveral set for Nov. 25
