G1.9+0.3 in 60 Seconds (06-30-2008)
About a hundred and forty years ago, the light from a supernova explosion in our galaxy reached the Earth, but no one saw it. The discovery of this supernova remnant helps astronomers better understand how often these stellar time-bombs go off in our galaxy.

Kepler's Supernova Remnant in 60 Seconds (05-07-2008)
The supernova explosion that created this object was witnessed on Earth about 400 ago years by many skywatchers, including the astronomer Johannes Kepler. This object, which now bears Kepler's name, is the remains of a massive star's demise.

Exploring The Large Magellanic Cloud (04-02-2008)
The Large Magellanic Cloud, known as the LMC, is a nearby satellite galaxy of our own Milky Way. At a distance of around 160,000 light-years, the LMC is the third closest galaxy to us. But the LMC is more than just a nice little sidekick.

The Crab Nebula in 60 Seconds (03-31-2008)
In 1054 A.D., a star's death in the constellation Taurus was observed on Earth. Now, almost a thousand years later, a superdense neutron star left behind by the explosion is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula.

When Will History Repeat Itself? (10-31-2007)
Astronomers think that a supernova should go off in our own Milky Way galaxy every 50 years or so. When was the last one we've seen? Probably 1604. Yes, that's over 400 years ago. This being astronomy however, things will undoubtedly average out over the long run, but in the meantime, we're left without a recent supernova in our Galaxy to study. Luckily for us, astronomers from previous centuries were on the case.
