Bizarre Six-Tailed Asteroid Dumbfounds Scientists
coondoggie writes "Many images from deep space are so cool, weird and unusual it is hard to believe they are real sometimes. This is one of them. Astronomers looking deep into the asteroid belt through NASA's Hubble Space Telescope say they have spotted an asteroid, designated P/2013 P5, with six comet-like tails of dust radiating from it like spokes on a wheel or a spinning garden sprinkler."
They're thrusters.
So I was looking for some spectacular six tailed swastika there, but, meh, some smokey trails.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
Why do so many of these stories have things like "dumbfounded" or "baffled" in the title? Are these scientists just standing there, exclaiming to everyone who will listen - "I'm just so gosh-darn BAFFLED!" Not from any scientist I've met - but it's always reported as such, as if unknowns weren't a crucial element of the whole, you know, SCIENTIFIC PROCESS.
Yeesh.

comets are icy and have tails when close to sun due to outgassing.
Asteroids (minor planets that are stony, metallic, or carbon compound based) can have tails for various reasons, some covered in the article.
this is not just knowledge for knowledge's sake. this is part of efforts to observe planetoids and asteroids to determine if there's risk of collision with Earth, determining feasibility of mining asteroids for resources, or even plain and simple adding to data sets observing how planetoids and asteroids interact with space
a lot of basic science isn't about finding groundbreaking stuff all the time. in fact, if you're doing research only looking for the "groundbreaking stuff", you're doing science wrong. much of science is straight observation. and it is USEFUL.
