Latest Galaxy morphological classification 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.
A team of astronomers lead by Masami Ouchi of the University of Tokyo has found the most vigorous star-forming galaxy yet seen, from a period of time in the early stages of the creation of the universe known as ‘cosmic dawn’.
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.
Scientists have developed machine-learning codes modeled on the human brain that can be used to classify galaxies accurately and efficiently.
A spectacular new image of an unusual spiral galaxy in the Coma galaxy cluster has been created from data obtained by the Advanced Camera for Surveys on the Hubble Space Telescope.
Astronomers at The University of Nottingham have identified a type of galaxy that could be the missing link in our understanding of galaxy evolution.
This is a unique NASA Hubble Space Telescope view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight.
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...
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...
