Here we are again, representing Galaxy Zoo at Dragon*Con. This is an enormous gathering of science-fiction and fantasy fans, aficionados of science, gaming, costuming, offbeat music – all packed into downtown Atlanta’s five largest conference hotels, every Labor Day holiday weekend. It’s a huge Con – the number of people here at one time or [...]
We have a team working at Kitt Peak again, this time using a spectrograph to chase down Voorwerpjes. As the Dutch diminutive indicates, these are like Hanny’s Voorwerp, only smaller. They are clouds of gas within galaxies (or out to their edges) which are ionized by a luminous active galactic nucleus. In most of these, [...]
Following on from my post about the Hubble diagram, I thought I’d mention a bit about the main types of galaxies that are out there. Galaxies come in three basic types: spirals, ellipticals and irregulars. Each of these three broad morphologies of galaxy tells us a little about what is going on inside the galaxy itself. [...]
We have just started the Polish version of the Galaxy Zoo Hubble! To get to it, hover your mouse over the small flag icon in the upper left corner of the main page. Otworzyliśmy polską wersję Galaxy Zoo Hubble. Aby tam dotrzeć, trzeba przejechać myszką nad ikoną z angielską flagą w lewym górnym rogu strony głównej.
Studies of Hubble Space Telescope images of the distant Universe revealed that the galaxy types seen nearby were still present, but generally become “messier” the further back in time one looks. Furthermore, there appeared to be types of distant galaxies that we do not see today. Many of these galaxies comprise knots or clumps, forming “chains”, “tadpoles” and “clump clusters”.
Some of you may have noticed that on Thursday we made a couple of small changes to the flow of questions that are asked for each object in Galaxy Zoo: Hubble. Both of these changes relate to the set of additional questions which we introduced during the switch from Galaxy Zoo 2 to Galaxy [...]
Have you ever looked at the Voorwerp and said to yourself, “Doesn’t that look like the Swamp Thing?” Or maybe you’ve seen Kermit the Frog dancing, or a maybe you see foliage run amok. There is just something about the Voorwerp that make me, for one, want to anthropomorphize it as a monster, and I’m betting [...]
