Latest Spiral galaxy Stories
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.
The intimate details of 100 galaxies in the local universe have been published by the Calar Alto Legacy Integral Field Area survey (CALIFA).
NASA's Chandra X-ray Observatory has identified one of the lowest mass supermassive black holes ever observed in the middle of a galaxy that one would not expect to harbor this type of beast.
While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it.
Researchers have found that less than half of Generation X adults can identify our own home in the universe, the spiral galaxy in which we reside.
When massive galaxies belly-up to the interstellar buffet, their centers expand as they gobble up other galaxies that contain billions and billions of stars, according to a new report from University of Utah astronomers.
NASA is lending the Galaxy Evolution Explorer (GALEX) to the California Institute of Technology (Caltech) in Pasadena, where the spacecraft will continue its exploration of the cosmos.
New instrument shows the gaseous halos of galaxies are much larger and more massive than the distribution of stars within the galaxy.
A galaxy with a combination of characteristics never seen before is giving astronomers a tantalizing peek at processes they believe played key roles in the growth of galaxies and clusters of galaxies early in the history of the Universe.
A new study, published in Physical Review Letters and available online, offers that a controversial theory which challenges the existence of dark matter has been kept afloat by studies of gas-rich galaxies.
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....
Elliptical Galaxy -- In astronomy, one of the main classes of galaxy in the Hubble classification and characterized by a featureless elliptical profile. Unlike spiral galaxies, elliptical galaxies have very little gas or dust and no stars have recently formed within them. They range greatly in size from giant ellipticals, which are often found at the centres of clusters of galaxies and may be strong radio sources, to tiny dwarf ellipticals, containing about a million stars, which are...
