The universe is full of quirks: stars that flash and go out without explanationgalaxies that are eaten, Black holes have become thugs. It is not surprising that among the billions of galaxies in the cosmos, some of them resemble strange.
From the formation of stars to the gravitational attraction of the surrounding galaxies to the whole collisions themselves, it is the forces that shape our universe. Especially, The search has found This star birth can strongly influence galactic environments, while the stars are formed from the surrounding dust and gas. From UV radiation which heats up the surrounding gas with stellar winds which put pressure and blow cavities through said gas, where this gas will in turn can shape the evolution of galaxies.
Galactic forms types
According to NASA, Your typical galaxy can be classified in a few given forms. There is the spiral of our own milky path, a wide and common class of galaxies generally comprising a bulge or a central bar, with additional arms.
There are also elliptical galaxies, which are more round or more oblong in shape with less definition than spiral galaxies. The lenticular galaxies are in a way a mixture between the previous two, lacking from a spiral arm and the ability to continually form new stars.
Then there are irregular galaxies, which cannot be carefully classified. By cutting out our creative visions on speed, these galaxies can have the shape of jellyfish, toothpicks or tadpoles. Here are six more known galaxies with the strangest forms of our universe.
1. Galaxy training: a wheel in the sky

Arms turning like the rays of a wheel, this galaxy, somewhat resembling a pin wheel or even a giant frisbee, was spotted by the James Webb space telescopeAbout 500 million light years from us.
Called a Collision ring galaxyIts shape and structure are the result of violent interactions between a larger spiral galaxy and a smaller, the impact causing shock waves which leave the galaxy of the well -named boxed wheel with a brilliant inner ring of many young clusters of stars, as well as a second exhale in continuous expansion ring. This creates one of the most extreme environments in which the stars can form.

2. Galaxy training: Cosmic penguins
What looks like a giant shiny penguin or a jumping porpoise was actually once a normal spiral galaxy, Appointed NGC 2936It approached his neighbor. Due to gravitational traction and interactions with an elliptical galaxy nearby, this formerly in regular form has been transformed and drawn in the body of a “penguin”. Its bright blue beak is actually a collection of young stars, with the Galactic Center of NGC 2936 remaining as its shiny white eye.
This penguin with starred eyes in the cosmos was spotted by the Hubble space telescope, and the astronomers predict that ultimately, the two collision galaxies merge completely.
3. Galaxy training: galactic jellyfish
Earlier in June, astronomers revealed their discovery of a galaxy resembling a rabbit earsswinging through the currents of the universe. Appointed NGC 4858, this galaxy was formed in extreme conditions while it was moving through the cluster of the Coma galaxy, which is essentially a hot gas calendron, extreme “wind” pressure and many other galactic companions.
While NGC 4858 moved through this group, the wind or “RAM pressure” began to strip its inner gas, leaving it thinner and longer, to the point of looking like a vaporous jellyfish. Likewise, his rabbit ears are also the result of the pressure and distortion of the RAM.
4. Galaxy training: egg the sunny side
With a central bulge made up of yellow stars resembling slightly decent yellow NGC 2276 is yet another example of an asymmetrical galaxy. Scientists believe that this distortion is due to a neighboring galaxy, NGC 2300, which draws more strongly on one side of the galaxy.
Other factors shaping this galactic egg could be the same pressure from Aries This formed the galaxy of discovery jellyfish this year, which could play an even more important role in the formation of the galaxy than the tidal interactions.
Astronomers have also noted that the formation of unusually intense stars taking place in NGC 2276 along its west side, which could be the result of an earlier confrontation with a smaller galaxy or NGC 2276 interactions with hot gas contained in clusters of galaxies.
5. Galaxy training: dance mouse

Captured by the Hubble space telescopeThis pair of galaxies looks like a few mice dancing with each other, with long brain stars and gas vaporous tails. These spiral galaxies are collided and will eventually merge. For the moment, however, NGC 4676 contains many clusters of young blue stars, whose formation has been triggered by gravitational interactions. The pair is also connected by a flow of material flowing between the two.
6. Galaxy Formation: Bullseye Galaxy
Sporting nine rings, The Galaxy Leda 1313424 Even offers a small smaller dwarf galaxy in its central heart. With eight rings originally identified by the astronomers of Hubble, then a ninth by the Keck Observatory, the Bullseye galaxy is the visual result of the impact of shock waves resulting from this galactic collision, in the same way that the way in which the surface of the water will be backwards over more and wider distances after a disturbance.
Over time, the rings of the Bullseye galaxy will continue to spread outwards and form stars. Although the universe is crowded and the contact between the galaxies is inevitable, it is a unique case in which a galaxy has passed directly in the center of another.
