Billion-Year-Old River of Stars Seen Flowing Near the Sun

A river of 4,000 stars has been detected just 330 light years from the Sun. This grouping is one billion years old, and has circled the outer edge of the Milky Way Galaxy four times since its formation. Astronomers found the formation using the Gaia space telescope, operated by the European Space Agency.

It’s Not Just You – The Galaxy IS Warped, After All!

The Milky Way Galaxy is typically thought to be a flat, spiral disk. But, new research from astronomers at Macquarie University suggest our home galaxy is warped. By studying the positions of certain well-understood stars, researchers were able to create the first 3D model of our home galaxy. They found that the Milky Way has a slight “s” shape when viewed from the side. Torque caused by the movement of stars closer to the center the galaxy appear to be causing the effect.

Hubble Discovers Dwarf Galaxy Playing ‘Where’s Waldo’ in Our Own Backyard

Astronomers using the Hubble Space Telescope accidentally found a previously-unknown galaxy, 28 million light years from Earth. This family of stars was found while researchers photographed the globular star cluster NGC 6752. Dubbed Bedin 1, this small, dim galaxy is believed to be around 13 billion years old, leading astronomers to describe it as a “living fossil” of the ancient Universe.

Milky Way Galaxy Headed for Collision – Brace Yourselves, Here Comes the Large Magellanic Cloud!

The Milky Way Galaxy is headed for a collision with the Large Magellanic Cloud in about 2.4 billion years, new research has found. Astronomers previously thought this satellite galaxy of the Milky Way would pass harmlessly by our home galaxy. But, new observations show it contains twice as much dark matter as previously believed, sending it on a collision course with our local family of stars. Galactic collisions are fairly common, and we are also due to collide with the much larger Andromeda galaxy, just over four billion years in the future.

The Andromeda Galaxy Was the Culprit – The Case of the Missing Galaxy

The Andromeda Galaxy, the closest large family of stars to the Milky Way, may be a galactic assassin. Astronomers from the University of Michigan have determined that this family of stars collided with another massive galaxy two billion years ago, nearly destroying it. Today, only the small dwarf galaxy, M32, remains, still located near Andromeda. In roughly four billion years, The Milky Way and Andromeda will collide, greatly altering both galaxies.

Asteroid 2015 BZ509 may have joined Our Family of Planets from an Alien Solar System

An asteroid orbiting backwards around the Sun may have come from another solar system, according to astronomers in France.
Asteroid 2015 BZ509 is roughly two miles across, and orbits the Sun at roughly the same distance as Jupiter. Computer simulations suggest the object may have joined our planetary family four-and-a-half billion years ago, just as the Earth and other planets were being formed.
