What's happening to this spiral galaxy?  spiral galaxy Although details remain uncertain, it surely has to do with an ongoing battle with its smaller galactic neighbor. The featured galaxy is labelled UGC 1810 by itself, but together with its collisional partner is known as Arp 273. The overall shape of the UGC 1810 -- in particular its blue outer ring - is likely a result of wild and violent gravitational interactions. This ring's blue color is caused by massive stars that are blue hot and have formed only in the past few million years. The inner galaxy appears older, redder, and threaded with cool filamentary dust. A few bright stars appear well in the foreground, unrelated to UGC 1810, while several galaxies are visible well in the background. Arp 273 lies about 300 million light years

It was the first galaxy to be classified as a spiral galaxy. Recently it was estimated to be 23 ± 4 million light-years from our Milky Way galaxy.

 A Misbehaving Spiral Galaxy regardless of its unassuming appearance, the edge on spiral galaxy captured in the left half of of this NASA/ESA Hubble space Telescope photograph is absolutely quite wonderful. Space in Images A Misbehaving Spiral Galaxy Located about one billion light-years in the constellation of Eridanus, this placing galaxy known as LO95 0313-192  has a spiral form similar to that of the Milky way. It has a big valuable bulge, and hands speckled with brightly sparkling gas mottled by means of thick traces of dim dirt. Its companion, sitting quite inside the right of the frame, is known as a substitute unpoetically as [LOY2001] J031549.8-190623.

galaxies and stars
  In space, being outshone is an occupational hazard. This NASA/ESA Hubble Space Telescope image captures a galaxy named NGC 7250. Despite being remarkable in its own right '” it has bright bursts of star formation and recorded supernova explosions'” it blends into the background somewhat thanks to the gloriously bright star hogging the limelight next to it. The bright object seen in this Hubble Telescope captures image is a single and little-studied star named TYC 3203-450-1, located in the constellation of Lacerta (The Lizard). The star is much closer than the much more distant galaxy. Only this way can a normal star outshine an entire galaxy, consisting of billions of stars. Astronomers studying distant objects call these stars 'foreground stars' and they are often not very happy ab

Sunny Side Up What may first appear as a sunny side up egg is actually NASA/ESA Hubble Space Telescope's face-on snapshot of the small spiral galaxy NGC 7742. But NGC 7742 is not a run-of-the-mill spiral galaxy. In fact, this spiral is known to be a Seyfert 2 active galaxy, a type of galaxy that is probably powered by a black hole residing in its core. The core of NGC 7742 is the large yellow 'yolk' in the center of the image. The lumpy, thick ring around this core is an area of active star birth. The ring is about 3,000 light-years from the core. Tightly wound spiral arms also are faintly visible. Surrounding the inner ring is a wispy band of material, which is probably the remains of a once very active stellar breeding ground.

Spiral Galaxy a Key to the universe expansion rate This view from the NASA/ESA Hubble Space Telescope shows the beautiful spiral galaxy NGC 5584. This galaxy has played a key role in a new study that measures the expansion rate of the Universe to greater accuracy than ever before. NGC 5584 was first spotted as a faint glow in the constellation of Virgo by the great visual observer E. E. Barnard, back in 1881, using just a 12.5-cm telescope. But, by bringing the power of Hubble to bear, the galaxy can be resolved into thousands of separate stars. Some of these stars vary in brightness and are classified as Cepheids. These are brilliant pulsating stars with a remarkable property once the time it takes a Cepheid to brighten and fade is known, then it is possible to find how bright it actu...

dusty spiral galaxy amazing Picture In 1995, the majestic spiral galaxy NGC 4414 was galaxy pictures, by the Hubble Space Telescope as part of the HST Key Project on the Extragalactic Distance Scale. An international team of astronomers, led by Dr. Wendy Freedman of the Observatories of the Carnegie Institution of Washington, observed this galaxy on 13 different occasions over the course of two months. galaxy pictures were obtained with Hubble's Wide Field Planetary Camera 2 (WFPC2) through three different color filters. Based on their discovery and careful brightness measurements of variable stars in NGC 4414, the Key Project astronomers were able to make an accurate determination of the distance to the galaxy.

Galaxies Merging Creates Tails of Star Birth

Galaxies Merging Creates Tails of Star Birth

Nature Updates
Not surprisingly, interacting galaxies have a dramatic effect on each other. Studies have revealed that as galaxies approach one another massive amounts of gas are pulled from each galaxy towards the center of the other until ultimately, the two merge into one massive galaxy. NGC 2623 is in the late stages of the merging process, with the centers of the original galaxy pair now merged into one nucleus, but stretching out from the center are two tidal tails of young stars, a strong indicator that a merger has taken place. During such a collision, the dramatic exchange of mass and gasses initiates star formation, seen here in both the tails. *The prominent lower tail is richly populated with bright star clusters*— 100 of them have been found in these observations. These star clusters
