Space Fan News #2: Echoes From a Quasar That No Longer Exists

Here's the press release: http://hubblesite.org/newscenter/archive/releases/2011/01/image/a/

Don't forget to check out Galaxy Zoo:

A Dutch schoolteacher discovered an enigmatic object while classifying galaxies in the Sloan Digital Sky Survey in 2007. Astronomers took a closer look with the Hubble and found a remarkable set of circumstances.

Thanks for all the positive feedback Space Fans, it makes doing these vids so easy.

hello mr. t...darnell i was wondering if you work with astronomy or if it's "just" a hobby?

[tdarnell]

@nybotheveg It's both. I'm a science technologist and software engineer at the Space Telescope Science Institute and I have several telescopes at home I use as often as time permits.

[tdarnell]

@totallyfreeenergy Those question are precisely some of the ones they're trying to answer over at Galaxy Zoo. They've published papers about this, even noticed biases in the people doing the classifications. You really should check it out, it's really interesting!

"Space Oddity" sounded more like a David Bowie reference to me.

Do ypui know what is the Distance between the Earth and the gas cloud ?

If the hole is only 20 000 LY across, it seems that the gas cloud is MUCH closer to us than the Quasar.... It is surprising to see that a quasar can ignite stars so far away...

It's a mini lymon alpha blob! I love those things they're usually allot bigger being as big as 6.5 million light years from Sid to side. This right here is basically a galactic nebula seeing a galaxy form.

Excellent video however you're self deprecation over a dutch word was mildly jarring.

Good and very informative video :)

That green gas massed looked like a dragon/godzilla head :D or maybe i'm just looked a little too much ink tests.....

[nucliosis]

Cool. Thanks for the informative vid

Thats a good cartoon! i get it... the quasar is mad because it doesn't emit a red spectrum of photonic radiation. so it forms some stars. am i reading into things to much? HA!

[okkedulle]

kudos tony for trying the dutch it was quite good !

nice vid as usual

David Bowie rocks!
