Latest Barred spiral galaxy Stories
According to NASA, galaxies can come in many different shapes and sizes, and their orientation relative to us can sometimes make them look even more bizarre than usual. The new photo of the so-called “Little Sombrero” got us thinking: What are some of the most unusual galaxies ever discovered by astronomers? Here are a few of our favorites.
After years of active participating by the public – and a host of interesting discoveries by amateur astronomers and enthusiasts – the Galaxy Zoo project is releasing its first scientific finding to come out of the data.
The Hubble Space Telescope has revealed a new image of the galaxy Messier 83, which has hosted a large number of supernova explosions and is believed to have a double nucleus at its core.
Two teams used data from European Southern Observatory (ESO) telescopes to create a three-dimensional map of the central parts of the Milky Way. While crafting the map they found that the inner regions of the galaxy take on a peanut-like appearance from certain angles.
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 highlights the pockets of star formation along its arms.
The European Space Agency released an image this week of an interactive diagram known as the Hubble Tuning Fork which helps to describe the shape of galaxies, which can come in all different sizes.
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.
For the first time, two astronomers have explained the diversity of galaxy shapes seen in the universe.
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.
In a landmark study of more than 2,000 spiral galaxies, astronomers found that so-called barred spiral galaxies were far less plentiful 7 billion years ago than they are today, in the local universe.
Spiral Galaxy -- Among the galaxies, there are apparently three main categories, according to their appearance: the disk galaxies (`cosmic frisbies' according to P. Murdin, D. Allen, and D. Malin), consisting of a huge disk of stars and interstellar matter, which may form interesting patterns, the elliptical galaxies (`cosmic footballs') which are uniformly looking, ellipsoidal agglomerations of stars, and the irregular galaxies (`cosmic misfits') which cannot be integrated in this scheme....
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...
