An image of Smith's Cloud, taken in 2008 by the Green Bank Telescope. Smith's Cloud is a high-velocity cloud of hydrogen gas located in the constellation Aquila.

Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the National Science Foundation's .

Hubble Space Telescope astronomers are finding that the old adage “what goes up must come down” even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy named Smith Cloud. The invisible cloud is plummeting toward our galaxy at nearly 700,000 miles per hour.

Monstrous Cloud Boomerangs Back to our Galaxy

Hubble Space Telescope astronomers are finding that the old adage “what goes up must come down” even applies to an immense cloud of hydrogen gas outside our Milky Way galaxy.

Boomerang Nebula, 5,000 light years away. This is an exploded star that is evolving toward a planetary nebula. The colors, regrettably, are false. They represent a mapping of the various orientations of polarized light from the gas cloud. In actuality the cloud is seen from light reflected off it from the central star. In unpolarized images it appears white.

Smith's Cloud is approaching the  Milky Way's disk at a 45-degree  angle and with a speed exceeding  over 150 miles (240 km) per  second (more).  The collision may trigger a period of rapid star formation fueled by the new gas and the shock from the collision. Some theories say that the ring of bright stars near the Sun, called Gould's Belt, was created by just such a collision event. http://www.nrao.edu/pr/2008/smithscloud/

A monstrous cloud is now heading to our Milky Way galaxy with enormous speed and is ready to collide with it, scientists said, adding that when it plows into our galaxy, the reaction will trigger star formation and provide gas for 2 million new stars.

Are aliens building a Dyson sphere around that super mysterious Kepler star? - In case you’ve been living under a rock or don’t keep up with space news, the Kepler space telescope observed the star KIC 8462852 and found that it’s displaying a super odd pattern of dimming that left astronomers puzzled.  Scientists aren’t ready to rule anything out in terms of what exactly is causing this phenomenon, and some have postulated an alien megastructure surrounding the star. | Redorbit

This infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye. 36 / 40 Photo by Comets Kick up Dust in Helix Nebula;

GALACTIC SMASH-UP  The many galaxies of the cluster Abell 3827 appear in this Hubble Space Telescope photograph. The center of the cluster contains four colliding galaxies (yellow blobs). The bluish circle around the galaxies is the light from a more distant galaxy bending around the cluster’s center due to gravity from both stars and dark matter. ~~ ESO

Galactic split provides clue to dark matter mystery

An oddly divided galaxy may provide the first evidence that dark matter particles interact through a force other than gravity.

Two very different glowing gas clouds in the Large Magellanic Cloud | ESO's Very Large Telescope has captured a detailed view of a star-forming region in the Large Magellanic Cloud — one of the Milky Way's satellite galaxies. This sharp image reveals two glowing clouds of gas. NGC 2014 (right) is irregularly shaped and red and its neighbour, NGC 2020, is round and blue. These odd and very different forms were both sculpted by powerful stellar winds from extremely hot newborn stars..
