The Horsehead Nebula, the number 1 seed in the Hypatia Division and a favorite to take the whole thing.

In the Fleming Division's craziest upset so far, top-seeded Nebula NGC 5189 suffered a crushing first-round defeat to Galaxy M74. Look for more insanity tonight as the Pillar in Carina is set to take on Gas Jet HH 110 in what promises to be a tightly contested matchup.

It's Hubble Madness 2014, where space nerds break out hot wings and beer to watch the Hubble telescope's most stunning images compete in an elaborate bracket. Throughout March, Hubble will be hosting the competition on its Facebook page and live tweeting from #HubbleMadness.

Hubble Madness is a cutthroat, single-elimination game. Users vote once a day, then wait with bated breath to find out whether their beloved celestial object will advance to the next round. No word yet how Nate Silver is handicapping the second-round matchup between Star Cluster NGC 3603 and Galaxy Group Arp 274.

So if your March Madness bracket just isn't working out, take heart. Comet ISON has had a good run, and we're betting that it will last far longer than it did in perihelion—at least to until the Final Four. And that's more than you can say for Duke's performance last week.
