Galaxy Zoo Talk

A collection of Collections!

  • Capella05 by Capella05 moderator

    One of the most powerful features of Talk is the ability to create collections:-)

    Instead of creating dozens of separate threads for the various catalogues / objects - we are going to maintain a index of collections.

    For each collection that we index, we will include a definition and examples - just so you know what we are looking for!

    Be sure to click on 'info' for more information on the relevant collection.

    All you need to do is #hashtag the image with the respective tag, and the collection will get continuously built 😃
    We are also looking for volunteers to manage the collections - in other words to remove the images that do not conform. If you are interested, and have a few classification under your belt - please contact me!

    If you would like a collection added to the 'Index', please PM @Capella05 - you can post at the end of this thread, but it will eventually be subsumed by the most recent collection 😃

    Thanks!

    GZ Talk Team.

    NGC Collection ( #NGC) - CGZL00003q

    The New General Catalogue of Nebulae and Clusters of Stars (abbreviated as NGC) is a well-known catalogue of deep-sky objects in astronomy compiled by John Louis Emil Dreyer in 1888, as a new version of John Herschel's Catalogue of Nebulae and Clusters of Stars.

    You will need to look on SkyServer to find out if it is tagged as a NGC object. The origins of this particular collection are listed here 😃

    Thanks Brooke!

    Gravitational lensing (#lens) - CGZL00000h

    My personal favourite collection... that is going to be refined over the coming months 😃

    A gravitational lens refers to a distribution of matter (such as a cluster of galaxies) between a distant source (a background galaxy) and an observer, that is capable of bending (lensing) the light from the source, as it travels towards the observer. This effect is known as gravitational lensing and is one of the predictions of Albert Einstein's general theory of relativity.

    UGC Collection (#UGC) - CGZL00003w

    The Uppsala General Catalogue of Galaxies (UGC) is a catalogue of 12921 galaxies visible from the northern hemisphere.

    You will need to look on SkyServer to find out if it is tagged as a UGC object.

    Asteroids! (#asteroid) - CGZL00003x

    Asteroids sometimes pass overhead as the telescope is observing. As they slowly move across the sky, they are captured in successive images taken in the different coloured filters. When the images are stacked, we are left with a series of blue, red and green dots.

    Markaryan objects (#mrk) - CGZL00003y

    The Markarian galaxies are a class of galaxies that have nuclei with excessive amounts of ultraviolet emissions compared with other galaxies... The nuclei of the galaxies had a blue colour that in a star would be classed from A to F. This blue core did not match the rest of the galaxy. The spectrum in detail tends to show a continuum that Markarian concluded was produced non-thermally. Most of these have emission lines and are interesting because of their energetic activity

    X-Shaped bulges (#x-shaped) - CGZL000040

    In this collection we are specifically looking for edge-on galaxies with 'X-shaped' or 'Boxy' Bulges.

    When staring directly at the centre of the galaxy, one can detect a faint, ethereal "X"-shaped structure. Such a feature, which astronomers call a "boxy" or "peanut-shaped" bulge, is due to the vertical motions of the stars in the galaxy's bar and is only evident when the galaxy is seen edge-on. This curiously shaped puff is often observed in spiral galaxies with small bulges and open arms, but is less common in spirals with arms tightly wrapped around a more prominent bulge, such as NGC 4710.

    Polar Rings (#polar) - CGZL000047

    A polar-ring galaxy is a type of galaxy in which an outer ring of gas and stars rotates over the poles of the galaxy.These polar rings are thought to form when two galaxies gravitationally interact with each other. One possibility is that a material is tidally stripped from a passing galaxy to produce the polar ring seen in the polar-ring galaxy. The other possibility is that a smaller galaxy collides orthogonally with the plane of rotation of the larger galaxy, with the smaller galaxy effectively forming the polar-ring structure.

    Comets! (#comet) - CGZL00004c

    A comet is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred metres to tens of kilometres across and are composed of loose collections of ice, dust, and small rocky particles.

    Nebula Collection (#nebula) - CGZL00004m

    A nebula is an interstellar cloud of dust, hydrogen, helium and other ionized gases. Originally, nebula was a name for any diffuse astronomical object, including galaxies beyond the Milky Way. The Andromeda Galaxy, for instance, was referred to as the Andromeda Nebula (and spiral galaxies in general as "spiral nebulae") before the true nature of galaxies was confirmed in the early 20th century by Vesto Slipher, Edwin Hubble and others.

    This collection needs a lot of work 😦 Known nebula need to be tagged, and incorrect images removed - let me know if you are interested (LizPeter?). It will also include all 3 generally recognised categories of nebulae, namely Diffuse, Planetary and Dark.

    Collisional Ring Galaxies (#collisional-ring) - CGZL00006q

    Collisional ring galaxies are believed to form when a compact galaxy collides head on with a larger disk or spiral galaxy.

    Hello I am Marianna and I am a senior in high school. I am part of my school's science research team an dam going to base my study off Galaxy Zoo. It would be very kind and helpful if anyone was willing to help out and suggest ideas! Thank you!

    Beautiful collection

    Marianna, just use all these collections here for your research and call it something whacky like, "what you won't see when you look up"
