Watch the videos "Panning Across Messier 77" and "Zooming in on Messier 77" Lee Rannals for redOrbit.com - Your Universe Online A stunning new image of the spiral galaxy Messier 77 captured by the Hubble Space Telescope was released today. The image of one of the most famous and well-studied galaxies features patches of red throughout the photo, which highlights the pockets of star formation along its arms. Messier 77, or NGC 1068, sits in the constellation Cetus about 45 million...
Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency (ESA) released an image this week of an interactive diagram known as the Hubble Tuning Fork. The diagram helps to describe the shape of galaxies, which can come in all different sizes. It ranges between elliptical galaxies, intermediate spirals, barred spirals and irregular shapes. The interactive map gives the examples of the different shapes of the galaxies, as well as a description in type, morphology,...
For the first time, the general public will be able to browse detailed infrared images of more than 200 galaxies. The pictures, originating from data from the orbiting Spitzer Space Telescope, will be released later this year. Dr George Bendo of the Jodrell Bank center for Astrophysics will highlight the new imagery in a preview at the National Astronomy Meeting in Manchester. The pictures are mid-infrared (24 micron wavelength) reprocessed images of nearby galaxies observed with Spitzer...
For the first time, two astronomers have explained the diversity of galaxy shapes seen in the universe. The scientists, Dr Andrew Benson of the California Institute of Technology (Caltech) and Dr Nick Devereux of Embry-Riddle University in Arizona, tracked the evolution of galaxies over thirteen billion years from the early Universe to the present day. Their results appear in the journal Monthly Notices of the Royal Astronomical Society.Galaxies are the collections of stars, planets, gas and...
Just as many people are surprised to find themselves packing on unexplained weight around the middle, astronomers find the evolution of bulges in the centers of spiral galaxies puzzling. A recent NASA/ESA Hubble Space Telescope image of NGC 4710 is part of a survey that astronomers have conducted to learn more about the formation of bulges, which are a substantial component of most spiral galaxies.When targeting spiral galaxy bulges, astronomers often seek edge-on galaxies, as their bulges...
A frequent sign of the maturity of a spiral galaxy is the formation of a ribbon of stars and gas that slices across the nucleus, like the slash across a "no smoking" sign.In a landmark study of more than 2,000 spiral galaxies from the largest galaxy census conducted by NASA's Hubble Space Telescope, astronomers found that so-called barred spiral galaxies were far less plentiful 7 billion years ago than they are today, in the local universe.The study's results confirm the idea that...
MADISON - With the help of NASA's Spitzer Space Telescope, astronomers have conducted the most comprehensive structural analysis of our galaxy and have found tantalizing new evidence that the Milky Way is much different from your ordinary spiral galaxy. The survey using the orbiting infrared telescope provides the fine details of a long central bar feature that distinguishes the Milky Way from more pedestrian spiral galaxies. "This is the best evidence ever for this long central bar in...

Images of Two Magnificent Spiral Galaxies from ESO Data Archive ESO --Â What does the Galaxy in which we live look like? It is almost certain that we will never be able to send a probe out of our Milky Way to take a snapshot, in the same way as the first satellites could do to give us striking images of planet Earth. But astronomers do not need this to imagine what our bigger home resembles. And they have a pretty good idea of it. The Milky Way with its several hundreds of billion stars is...

Galaxy -- Stars are almost always found in collections called galaxies, together with gas, dust, and large amounts of dark matter detected by its gravitational effects. These are all held together by gravitational attraction and orbit a common centre. There is some evidence that black holes may exist at the centre of some or most galaxies. Galaxies come in three main types: ellipticals, spirals, and irregulars. A slightly more extensive description of galaxy types is given by the Hubble...
