Hubble Tuning Fork Interactive Diagram
2012-11-19 13:27:53

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,...

Rare Massive Galaxy From Early Stages Of Universe Creating Massive Numbers Of Stars
2011-12-22 11:10:16

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 750-million-year-old galaxy, known as GN-108036 among was forming stars equivalent to about a hundred Suns per year, when most of the universe was still cold and dark, reports Rob Waugh for Mail Online. The galaxy, 12.9 billion light-years away, was...

Scientists Study 'Galaxy Zoo' Using Google Maps An Thousands Of Volunteers

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. A group of volunteers of more than 200,000 participants of the galaxy classification project Galaxy Zoo contributed to this research. More than two thirds of spiral galaxies, including our own Milky Way, display a central bar that can extend for thousands of light years. These colossal...

Scientists at University College London (UCL) and the University of Cambridge have developed machine-learning codes modeled on the human brain that can be used to classify galaxies accurately and efficiently. Remarkably, the new method is so reliable that it agrees with human classifications more than 90% of the time. The research will appear in a paper in the journal Monthly Notices of the Royal Astronomical Society. There are billions of galaxies in the Universe, containing anything between...

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. It reveals fine details of the galaxy, NGC 4921, and an extraordinary rich background of more remote galaxies stretching back to the early Universe. The Coma galaxy cluster, in the northern constellation of Coma Berenices, the hair of Queen Berenice, is one of the closest, very rich collections of galaxies in the...

Astronomers at The University of Nottingham have identified a type of galaxy that could be the missing link in our understanding of galaxy evolution. The STAGES study led by the University's Centre for Astronomy and Particle Theory examines galaxy evolution using images from the Hubble Space Telescope. A separate project "” Galaxy Zoo "” uses volunteers from the general public to classify galaxies. Both teams have identified a population of unusual red spiral galaxies that are...

This is a unique NASA Hubble Space Telescope view of the disk galaxy NGC 5866 tilted nearly edge-on to our line-of-sight. Hubble's sharp vision reveals a crisp dust lane dividing the galaxy into two halves. The image highlights the galaxy's structure: a subtle, reddish bulge surrounding a bright nucleus, a blue disk of stars running parallel to the dust lane, and a transparent outer halo. Some faint, wispy trails of dust can be seen meandering away from the disk of the galaxy out into the...

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...
