Latest Peculiar galaxies Stories
Long before the term "citizen science" was coined, the field of astronomy has benefited from countless men and women who study the sky in their spare time.
Astronomers have been observing the Whirlpool Galaxy since the 18th century, but they’ve never seen it like this.
A detailed study of an enormous cloud of hot gas that envelops two large, colliding galaxies has been made using NASA’s Chandra X-ray Observatory. This oversized gas reservoir contains as much mass as 10 billion Suns, is 300,000 light years across, and radiates more than 7 million degrees Kelvin.
A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy.
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 most elliptical galaxies are considered vintage, retired star making neighborhoods, astronomers have found one that has a personality more like that of a pinwheel-shaped spiral galaxy.
An image of an isolated galaxy located approximately nine million light years from the Milky Way has been captured using the Hubble Space Telescope.
Scientists have found a way to accurately follow the birth and evolution of thousands of galaxies over billions of years.
Astronomers studying the galaxy NGC 4151 with ESA's XMM-Newton space observatory have detected X-rays emitted and then reflected by ionised iron atoms very close to the supermassive black hole hosted at the galaxy's core.
The strange galaxy Centaurus A is pictured in a new image from the European Southern Observatory (ESO). With a total exposure time of more than 50 hours this is probably the deepest view of this peculiar and spectacular object ever created.
The M51 Group, located in Canes Venatici, is named after the brightest galaxy in the group, the Whirlpool Galaxy (M51A). The few other notable members include the companion galaxy to the Whirlpool Galaxy (M51B) and the Sunflower Galaxy (M63).
The Centaurus A/M83, divided into subgroup Cen A and M83, is a complex group of galaxies located within Hydra, Centaurus, and Virgo constellations. The Cen A Subgroup, at a distance of 11.9 Mly (3.66 Mpc), is centered around Centaurus A, a nearby radio galaxy. The M83 Subgroup, at a distance of 14.9 Mly (4.56 Mpc), is centered around the Messier 83 (M83), a face-on spiral galaxy. Due to the physical closeness of both subgroups they are sometimes identified as two groups sometimes as one....
Stephan's Quintet in the constellation Pegasus is a visual grouping of five galaxies which four form the first compact galaxy group ever discovered. The group was discovered by Ã‰douard Stephan in 1877 at Marseilles Observatory and is the most studied of all the compact galaxy groups. NGC 7320, which has extensive H II regions, is the brightest member of the visual grouping and is where active star formation is occurring. Hickson Compact Group 92, which contains four of the five...
Within the Hydra, Centaurus, and Virgo constellations a complex group of galaxies resides called Centaurus A/M83. There are two subgroups within Centaurus A/M83. The first is Cen A, at a distance of 11.9 Million Light Years, is centered around Centaurus A, a close by radio galaxy. The other subgroup, M83, is at a distance of 14.9 Million Light Years and is centered around the Messier 83. Since there are two subgroups Centaurus is sometimes identified as one group and sometimes two, it will be...
Whirlpool Galaxy -- Discovered 1773 by Charles Messier. The famous Whirlpool galaxy M51 was one of Charles Messier's original discoveries: He discovered it on October 13, 1773, when observing a comet, and described it as a "very faint nebula, without stars" which is difficult to see. Its companion, NGC 5195, was discovered in 1781 by his friend, Pierre Mchain, so that it is mentioned in Messier's 1784 catalog: `It is double, each has a bright center, which are separated 4'35". The two...
