A new theory shows that Jupiter may have briefly visited our inner solar system, decimating what was there and setting the stage for the formation of the inner rocky planets that we know and love.
The latest evidence shows with a high degree of confidence that we are currently undergoing Earth’s 6th Mass Extinction Event.
Do a google search on earth’s most massive extinction events in which a significant chunk of its species disappeared off the face of the earth. You will most often find that 5 such events have been identified throughout earth’s history, the most famous being the extinction 60+ million years ago that wiped out the Dinosaurs (except the birds of course).
Space professionals and aficionados the world-over are rejoicing over the news that Philae, the first vehicle to ever make a “soft” landing on a comet, has awakened from its hugely disappointing shadow-induced slumber.
It wasn’t that long ago, November of 2014, that the monumental achievement was announced. After 30 years of effort and a decade of circuitous space travel, the European Space Agency’s Rosetta probe had disgorged its lander module, Philae, which landed on comet 67P. This had never been done before and this milestone was made even sweeter coming after a host of problems and technical issues that continually plagued the mission.
Hubble’s most advanced camera is producing its best images ever including an image of one of the loneliest nearby galaxies, NGC-6503
As you can see, NGC-6503 is a striking galaxy. It is a dwarf spiral located 18 million light years away in the constellation Draco (Latin for Dragon). It’s a relatively little guy only 30,000 light years across or one third the length of the Milky Way.
After 33 months of herculean effort, DARPA’s Robotic Challenge has finally ended with South Korea’s HUBO robot coming out on top followed by the United States’ Running Man and Chimp.
This whole 3 year robo-olympic competition had it’s genesis ultimately linked to the tragic Fukushima earthquake in April 2011. That earthquake and resulting tsunami heavily damaged the Fukushima nuclear reactor causing 3 of its 6 reactors to meltdown. This event joined Chernobyl as the only time we have ever reached a level 7 on the International Nuclear Event Scale.
After at least 3 decades, scientists may finally have a decent handle on the mystery of where proton spin comes from. Particle spin in this context is essentially a form of inherent angular momentum analogous to a spinning top but like all analogies (especially Quantum Mechanical ones), they only take understanding so far. It was
