Gas Cloud Flung Out Of Milky Way Is Coming Back For Revenge by Liljeez(m): 10:03pm On Feb 16, 2016 |
This composite image shows what Smith’s Cloud
would look like in the night sky, if it were visible
to human eyes. The cloud is on a course to
collide with the Milky Way in about 30 million
years. The cloud appears in false-color, radio
wavelengths as observed by the Green Bank
Telescope in West Virginia. More updates coming

[b]This time, it's personal. A massive cloud ejected from the outskirts of the Milky Way galaxy about 70 million years ago is now hurtling back toward the disk at breakneck speed. The boomeranged collection of gas, known as Smith's Cloud, was discovered in 1963, and scientists say it will collide with the Milky Way in about 30 million years. But a new study looking the composition of the cloud shows that it shares a similar chemical signature as the outer disk of the Milky Way. Smith's Cloud is 11,000 light-years long by 2,500 light-years wide (for comparison, the Milky Way is about 100,000 light-years in diameter), and is speeding toward the Milky Way at nearly 700,000 miles per hour. While it is invisible to the naked eye, if humans could see it in the night sky, it would appear to be about 30 times the size of the full moon, according to NASA. [ Stunning Photos of Our Milky Way Galaxy (Gallery)] To determine the cloud's composition, the authors of the new research used NASA's Hubble Space Telescope. As light from background galaxies passes through the cloud, certain chemical elements inside the cloud absorb the light in specific wavelengths. The dips in brightness reveal which elements are present within the cloud. The researchers looked for sulfur, which provides a good gauge of how many elements heavier than hydrogen and helium are contained by the object.The picture below shows its trajectory and how its gonna fall into the milky way Cc Lasticlala Mynd44 Johnydon22 Explorers[/b]

Quite an ominous phenomenon.. how did it get ejected in the first place bro? |

johnydon22:As we knw,The smith cloud was ejected abt 70 million years...this was discovered in the 1960s through complex calculations...as at that time it was just an amorphous ball of gas....earlies scientists didnt really give it most thought,they initially thought it was a failed galaxy....just recently it gained some attention when it was discovered thru the hubble telescope that it was coming back...theres no particular reason now as to why it left the milky way but scientists are postulating that an enormous force blasted it out |

Liljeez:Some postulate its a remnant of the milky way formation. Well its pay back time |
