Supernova Cannon Expels Pulsar J0002

What would it take to shoot out a neutron star? There is a big bang. About 10,000 years ago, a massive star was destroyed by a supernova that created a pulsar and flung it out into the sky. Einstein@Home was used to discover the pulsar, which spins 8.7 times a second. The pulsar J0002+6216 is traveling over 1,000 kilometers per second and is fast enough to leave our galaxy. The trail of the pulsar extends to the left of the supernova remnant. There is a combination of radio images from the VLA and DRAO radio observatories as well as data from NASA's IRAS observatory. It's well known that supernovas can act as cannons, but what's not known is how they do it.

Explanation: What mysteries might be solved by peering into this crystal ball? In this case, the ball is actually a moon of Jupiter, the crystals are ice, and the moon is not only dirty but cracked beyond repair. Nevertheless, speculation is rampant that oceans exist under Europa's fractured ice-plains that could support life. Europa, roughly the size of Earth's Moon, is pictured here in an image taken a few days ago when the Jupiter-orbiting robotic spacecraft Juno passed within 325 kilometers of its streaked and shifting surface. Underground oceans are thought likely because Europa undergoes global flexing due to its changing gravitational attraction with Jupiter during its slightly elliptical orbit, and this flexing heats the interior. Studying Juno's close-up images may further humanity's understanding not only of Europa and the early Solar System but also of the possibility that life exists elsewhere in the universe.
