Latest Disc galaxy Stories
A pair of Australian astrophysicists has shown that the shape of a galaxy is determined by how fast it spins, according to a new report in The Astrophysical Journal.
The reddest galaxies with the largest central bulb show the largest bars -gigantic central columns of stars and dark matter-, according to a scientific study that used Google Maps to observe the sky.
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....
Lenticular Galaxy -- The lenticular galaxies are disk galaxies without any conspicuous structure in their disks. This is probably because they have either used up most of their interstellar matter, so that they consist of old stars only, which have found a smooth and even distribution in the disk by the time, or because the galaxy has not closely encountered any neighbor in the past few hundred million (or few billion) years. From their appearance, and also their stellar contents...
