And with "just" I mean 11.4 million years ago, even while Steve Fossey just detected this bright and rare Type Ia supernova using a ‘modest telescope in an unlikely spot: foggy north London.’ Scientists say that it will be visible in the sky soon, as it brightens up. Here you can see the supernova appearing in the sky, in a before an after image of M82, the Cigar Galaxy.

The Harvard-Smithsonian Center for Astrophysics reports on the discovery of a "reverse shock wave racing inward at Mach 1000" in the Tycho’s supernova remnant, making its particles glow as you can see in the photograph above. If you think the idea of a shockwave traveling inward is counterintuitive, you aren’t alone. This is what’s happening:

There goes any feeling of accomplishment us grown-ups had today. Ten-year-old Nathan Gray just discovered a supernova, unseating his own sister as the world’s youngest to do so. Talk about sibling rivalries.

Ohio State University astronomers have concluded that there’s a probability of almost 100 percent that a star will go supernova in the Milky Way during the next 50 years. The explosion, they said, will be visible from Earth.

This stunningly trippy object is W49B, a supernova remnant 26,000 light years away from Earth. It’s just a thousand years old, which in cosmological terms is not even a heartbeat in the life of a human. It may also be the birth place of a newborn black hole, the youngest ever detected in the galaxy. More »
This image reminds me of an ovum—a female egg. But it’s not inside anything on Earth. It’s floating in the vastness of space about 9,000 light years from here, in the constellation of Cassiopeia. It’s the Tycho supernova remnant. More »
