While the serpentine creatures regularly use their zapping powers to temporarily paralyze unlucky fish, they can also send out a shock that will cause hidden... ( Amina Khan ) While only just recently discovered using Hubble's Advanced Camera for Surveys, the galaxy known as KKs3 has been around for a long while
This halo is a big deal; it is estimated to contain half the mass of all the stars in the galaxy itself and is 1,000 times more massive than previous estimates suggested. Because the gas in the halo is dark, the team measured it by using the light from quasars, the very distant bright cores of active galaxies powered by black holes
ALMA witnesses assembly of galaxies in the early universe for the first time July 22, 2015 When the first galaxies started to form a few hundred million years after the Big Bang, the Universe was full of a fog of hydrogen gas. The results of the research, which also involved scientists from the National Astronomical Observatory of China (NAOC), are published in Astrophysical Journal Letters and The Astrophysical Journal
Andromeda Nebula Lies Outside Milky Way Galaxy

Curtis stated that bright diffuse nebulae are fairly close to Earth and are part of the Milky Way, while spiral nebulae are at great distances and not part of the Milky Way
A spiral galaxy like the Milky Way, Andromeda contains a concentrated bulge of matter in the middle, surrounded by a disk of gas, dust, and stars 260,000 light-years long, more than 2.5 times as long as the Milky Way. When Charles Messier labeled it M31 in 1764, he incorrectly credited the discovery of what was then called a nebula to the German astronomer, Simon Marius, who provided the first telescopic observation of the object
Milky Way Collision
When the galaxies collide, there is little chance that many stars will slam into each other directly because they are so spread out; however, the gas that lies between the stars can collide, heat up and trigger the formation of new stars. Andromeda and the Milky Way will pass through each other once, then fall apart for about a billion years, then pass again, and again until finally settling down to merge completely about 5 billion years from now
Andromeda And The Milky Way Might Collide Sooner Than We Think
To find and study the halo, the team sought out quasars, distant star-like objects that radiate tremendous amounts of energy as matter funnels into the supermassive black holes in their cores. Extending for at least 2 million light years, if we could see in our night sky it would be 100 times the diameter of the Moon or 50 degrees across!

The faint outer parts of a spiral galaxy are more susceptible to warping because they are less strongly bound by the gravitational and other forces that keep disk stars in a plane and are also more susceptible to the influence of neighboring galaxies. In this 2010 infrared image, dust heated by newborn, massive stars are depicted in yellow and red, which trace out the spiral arms, while mature stars are colored blue (more)

When will the Andromeda and Milky Way galaxies collide - Business Insider
The picture below is what the sky would look like on Earth if it the planet were around to see the end of the galaxy war: ScienceTV on YouTubeThe solar system will not be entirely unaffected during this collision. "If two galaxies actually collide with each other, the stars basically pass right between each other, and the chance of two stars directly hitting each other is really, really small," Van der Marel said in the video
The Hubble Space Telescope's deep views of the universe show such encounters between galaxies were more common in the past when the universe was smaller. The Hubble Space Telescope team, led by van der Marel, conducted extraordinarily precise observations of the sideways motion of M31 that remove any doubt that it is destined to collide and merge with the Milky Way
Once that happens, the two galaxies will become bound, dance around, and eventually merge to become one large elliptical galaxy -- over the next few billion years. Pictured above is an artist's illustration of the sky of a world in the distant future when the central parts of each galaxy begin to destroy each other

The scientists said: The galaxy is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both. For decades, astronomers have been saying that our home galaxy, the Milky Way, is destined someday to collide with the next-nearest spiral galaxy, in the direction of the constellation Andromeda
Andromeda galaxy will collide with Milky Way - CBS News
These violent collisions rarely occur so close to the Milky Way, and they captured the attention of many on Twitter, with the hashtag "GRBm31." Andromeda is known as galaxy m31. "Whereas the universe is expanding and galaxies are generally getting farther and farther away from one another with time, the galaxies in the Local Group are bound together by family ties in the form of their mutual gravity," he wrote.But there is nothing to worry about, he noted, because long before that, the Earth will have entered the solar system's "hot zone" and become too hostile to sustain human life, so no one will be around to experience the collision
