Latest Unbarred spiral galaxies Stories
When galaxies grow too massive to continue making their own stars, they begin cannibalizing other nearby galaxies, experts from the University of Western Australia and an international team of colleagues reported this week in the journal Monthly Notices of the Royal Astronomical Society.
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.
The Milky Way and Andromeda galaxy are dominant members of a small group of galaxies. However, not a lot has been known about the smaller galaxies that reside within our neighborhood in the universe.
Typically filled with only the oldest stars, which are relatively low in mass and appear red, giant elliptical galaxies have long baffled astronomers. These galaxies are mysteriously shut down with respect to star-forming activity
Astronomers writing in The Astrophysical Journal have answered a few more important questions about how so-called spiral galaxies get their arms.
A stunning new image of the spiral galaxy Messier 77 captured by the Hubble Space Telescope was released today. The image of one of the most famous and well-studied galaxies highlights the pockets of star formation along its arms.
Astronomers studying a violent explosion located 35 million light-years away from Earth in spiral galaxy NGC 1637 have provided a new view of the cosmic beauty.
The NASA/ESA Hubble Space Telescope – with a little help from an amateur astronomer – has produced one of the best views yet of nearby spiral galaxy Messier 106.
A new Hubble Space Telescope image has been unveiled of NGC 922, revealing the cosmic structure to be an unusual spiral galaxy.
At a distance of 3.9 Mpc from the Milky Way, the Sculptor Group is one of nearest groups of galaxies to the Local Gropu. Sculptor is made up of a loose group of galaxies near the south galactic pole. The Sculptor Galaxy (NGC 253) and a few other galaxies form a gravitationally-bound core in the center of this group, however, since they are only weakly bound the group may also be described as a filament. There also some other galaxies associated with the group but not gravitationally...
Virgo A Galaxy -- Discovered 1781 by Charles Messier. The giant elliptical galaxy M87, also called Virgo A, is one of the most remarkable objects in the sky. It is perhaps the dominant galaxy in the closest big cluster to us, the famous Virgo Cluster of galaxies (sometimes also called "Coma-Virgo cluster" which is more acurate, as it extends into constellation Coma), and lies at the distance of this cluster (about 60 million light-years). M87 lies well in the heart of the Virgo cluster...
Triangulum Galaxy -- The Triangulum Galaxy, Messier object M33, is a spiral galaxy of type Sc located in the constellation Triangulum. Triangulum is small relative to its larger neighbors such as the Milky Way and Andromeda Galaxy, but is about average compared to most spiral galaxies in the universe. Triangulum is a member of the Local Group of galaxies and may be a gravitationally bound companion of the Andromeda Galaxy. LGS 3, one of the small Local Group member galaxies, is itself...
Sunflower Galaxy (M63) -- Discovered 1779 by Pierre Mchain. M63 was the very first discovery of a Deep Sky object by Messier's friend, Pierre Mchain, who caught it up on June 14, 1779. On the same day, Charles Messier included it in his catalog. The Sunflower galaxy M63 is one of the early recognized spiral galaxies, listed by Lord Rosse as one of 14 "spiral nebulae" discovered to 1850. It has been classified as of Hubble type Sb or Sc, displaying a patchy spiral pattern which can...
Sombrero Galaxy -- Discovered by Pierre Mchain or Charles Messier in 1781. M104 is numerically the first object of the catalog which was not included in Messier's originally published catalog. However, Charles Messier added it by hand to his personal copy on May 11, 1781, and described it as a "very faint nebula." It was Camille Flammarion who found that its position coincided with Herschel's H I.43, which is the Sombrero Galaxy (NGC 4594), and added it to the official Messier list in...
