ne look at the Porpoise Galaxy, or NGC 2936, will tell you exactly where the name comes from. It looks just like a dolphin, though some say it looks more like a penguin protecting an egg. In reality, this is a system of two galaxies: The “dolphin” is actually part of NG 2936, while the “egg” is called Arp 142.

The dolphin portion used to be a spiral galaxy similar to the Milky Way, but the immense gravitational forces of the denser galaxy below has contorted its shape significantly. The dolphin’s “eye” is what used to be the spiral galaxy’s core. This galaxy is also within the Hydra constellation, and within a billion years or so, the pair will merge into one. For now, we’ll just enjoy the galactic equivalent of a clown making balloon animals.

galaxies Facts Atoms for Peace galaxy

peace galaxy | NGC 7252 is Only rarely does an astronomical object have a political association. However, the spiral galaxy NGC 7252 acquired exactly that when it was given an unusual nickname.

In December 1953, the US President Dwight D. Eisenhower gave a speech advocating the use of nuclear power for peaceful purposes. This “Atoms for Peace” speech was significant for the scientific community, as it brought nuclear research into the public domain, and NGC 7252, which has a superficial resemblance to an atomic nucleus surrounded by the loops of electronic orbits, was dubbed the Atoms for Peace galaxy in honour of this. These loops are well visible in a wider field of view image. galaxies Facts

This nickname is quite ironic, as the galaxy’s past was anything but peaceful. Its peculiar appearance is the result of a collision between two galaxies that took place about a billion years ago, which ripped both galaxies apart. The loop-like outer structures, likely made up of dust and stars flung outwards by the crash, but recalling orbiting electrons in an atom, are partly responsible for the galaxy’s nickname.

This NASA/ESA Hubble Space Telescope image shows the inner parts of the galaxy, revealing a pinwheel-shaped disc that is rotating in a direction opposite to the rest of the galaxy. This disc resembles a spiral galaxy like our own galaxy, the Milky Way, but is only about 10 000 light-years across — about a tenth of the size of the Milky Way. It is believed that this whirling structure is a remnant of the galactic collision. It will most likely have vanished in a few billion years’ time, when NGC 7252 will have completed its merging process. galaxies Facts

The Whirlpool Galaxy, also known as Messier 51a, M51a, or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus in the constellation Canes Venatici (the Hunting Dogs). 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.

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.

Jets, outbursts of excellent heated fuel shifting at near the rate of mild, have long been related to the cores of giant elliptical galaxies, and galaxies within the growth of emerging. but, in an surprising discovery, astronomers determined LO95 0313-192 to have excessive radio jets spewing out from its center! The galaxy seems to have two greater regions which are also strongly emitting inside the radio a part of the spectrum, making it even rarer still.

the discovery of those large jets in 2003 no longer seen in this photo, but indicated in this earlier Hubble composite has been followed by the unearthing of a further three spiral galaxies containing radio-emitting jets in recent years. This growing class of unusual spirals keeps to raise enormous questions on how jets are produced inside galaxies, and how they’re thrown out into the cosmos.

super-rich galaxy

galaxies Facts super-rich galaxy.

This new image from the NASA/ESA Hubble Space Telescope shows the super-rich galaxy cluster Abell 1413. Located between the constellations of Leo (The Lion) and Coma Berenices, the cluster is over 2 billion light-years from Earth. This image is dominated by a large and highly elliptical galaxy called MCG+04-28-097, with a halo of stars extending for more than 6.5 million light-years.

Abell 1413 is part of the Abell catalog, a collection of over 4000 rich clusters of galaxies fairly close to Earth — at least from a cosmological perspective — their light took less than 3 billion years to reach us. The clusters are called rich due to the huge number of galaxies they contain. Abell 1413 is observed to contain more than 300 galaxies held together by the immense gravity of the cluster.

The strong interactions between these galaxies cause the material in the cluster to be heated to extremely high temperatures of almost 100 million degrees. Because of this, the cluster emits very strong X-ray radiation.

Visible distortions in the image can be seen in the form of arcs, caused by gravitational lensing

This image was created from optical and near-infrared exposures taken with the Wide Field Channel of Hubble’s Advanced Camera for Surveys (ACS). A version of this image was entered into the Hubble’s Hidden Treasures image processing competition by contestant Nick Rose.
Notes

[1] The galaxies at the center of Abell 1413 are found to be very highly elliptical whereas those at the periphery are more spherical.

[2] Gravitational lensing occurs when the intense gravity of the cluster bends space-time around it, causing a range of bizarre and beautiful optical phenomena for galaxies located in the background.


Milky Way Galaxy

 From our vantage point in the Milky Way Galaxy, we see NGC 6946 face-on. The big, beautiful spiral galaxy is located just 10 million light-years away, behind a veil of foreground dust and stars in the high and far-off constellation of Cepheus. From the core outward, the galaxy’s colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the loose, fragmented spiral arms.

NGC 6946 is also bright in infrared light and rich in gas and dust, exhibiting a high star birth and death rate. In fact, since the early 20th century at least nine supernovae, the death explosions of massive stars, were discovered in NGC 6946. Nearly 40,000 light-years across, NGC 6946 is also known as the Fireworks Galaxy. This remarkable portrait of NGC 6946 is a composite that includes image data from the 8.2 meter Subaru Telescope on Mauna Kea.

dusty spiral galaxy galaxies Facts.

In 1995, the majestic spiral galaxy NGC 4414 was galaxy picturesby 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.


“Loopy” Galaxy

 NGC 7714 is a spiral galaxy 100 million light-years from Earth — a relatively close neighbour in cosmic terms. The galaxy has witnessed some violent and dramatic events in its recent past. Tell-tale signs of this brutality can be seen in NGC 7714’s strangely shaped arms, and in the smoky golden haze that stretches out from the galactic centre — caused by an ongoing merger with its smaller galactic companion NGC 7715, which is off the top of the frame of this image.

hat’s in a name? When it comes to catchy monikers, most galaxies come up short.

But perhaps that isn’t so surprising. With an estimated 100 billion to 200 billion galaxies in the known universe, it’s no wonder that the majority of galaxies that have been identified thus far go by a catalog number: M51, GN-z11, and IOK-1, for example. Those arrangements of numbers and letters are loaded with meaning for astronomers, but they don’t exactly inspire the imagination.

However, a handful of galaxies have fared a little better in the naming department — usually the ones that are distinctively shaped, extremely close by and easy to observe, or just exceptionally photogenic. Here’s a look at some of these galaxies with standout names.


Sombrero Galaxy

The Sombrero Galaxy, unsurprisingly, bears a striking resemblance to the hat of the same name. It has a large bulge in the center where some imaginary cosmic giant’s head might go and a broad, sweeping “brim.”

When we look at the bulge a bit closer, you can see that it’s actually made up of several different clusters of stars, rather than just one big one. The brim is pretty strange, too: Its intricate detail is another one of those things about space that makes science scratch its head. We’re not sure how rings like this were able to form. It’s also highly likely that the heart of the Sombrero Galaxy harbors a massive black hole. galaxies Facts
