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.Read More Billion-Year-Old River of Stars Seen Flowing Near the Sun
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.Read More It’s Not Just You – The Galaxy IS Warped, After All!
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.Read More Hubble Discovers Dwarf Galaxy Playing ‘Where’s Waldo’ in Our Own Backyard
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.Read More Milky Way Galaxy Headed for Collision – Brace Yourselves, Here Comes the Large Magellanic Cloud!
A supermassive black hole has been discovered within a tiny galaxy called UCD3. This finding, carried out by an international team at the Very Large Telescope in Chile, is only the fourth of its kind. Star families like UCD3 have masses tens of millions of times greater than the Sun, sitting in clusters just 300 light years in diameter.Read More Supermassive Black Hole Seen in Tiny Galaxy called UCD3
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.Read More The Andromeda Galaxy Was the Culprit – The Case of the Missing Galaxy
For the first time ever, astronomers have witnessed a black hole swallowing a star. The event took place 150 million years ago in a pair of colliding galaxies called Arp 299. The black hole was 20 million times larger than our own Sun, and was seen consuming a body twice the size of our stellar companion.Read More Black Hole Seen Eating Star for First Time Ever
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.
The earliest stars in the Universe formed just 250 million years after the big bang, according to astronomers working at the ALMA facility in Chile. Researchers also discovered the oldest oxygen ever detected, from just 500 million years after the creation of the Universe. These discoveries push back the time when astronomers believe starlight first filled the Cosmos.Read More First Stars Formed Just 250 Million Years After Big Bang
For the first time ever, a supernova is seen in the first moments it erupts. Amazingly, it was spotted by an amateur astronomer. This is his story.Read More Amateur Astronomer Victor Buso Spots Supernova in First Moments of Explosion
