Thousands of galaxies classified in the blink of an eye

Astronomers have designed and trained a computer program that can classify tens of thousands of galaxies in just a few seconds, a task that usually takes months to accomplish. In research published today, astrophysicists from Australia have used machine learning to speed up a process...

Galaxies Have Magnetic Fields, Too! Images Here

Until recently, measuring faint magnetic fields for distant galaxies was an exceedingly hard thing to do. Telescopes simply weren’t sensitive enough to register such faint signals. In 2011, though, the famous Very Large Array (VLA) radio observatory in New Mexico was updated and equipped with...

Magnetized threads weave spectacular galactic tapestry

Threads of superheated gas and magnetic fields are weaving a tapestry of energy at the center of the Milky Way galaxy. A new image of this new cosmic masterpiece was made using a giant mosaic of data from NASA’s Chandra X-ray Observatory and the MeerKAT...

Galactic crash may have triggered solar system formation

The formation of the Sun, the Solar System and the subsequent emergence of life on Earth may be a consequence of a collision between our galaxy, the Milky Way, and a smaller galaxy called Sagittarius, discovered in the 1990s to be orbiting our galactic home....

Giant molecular outflow detected from the quasar PDS 456

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, astronomers have detected a galaxy-wide molecular outflow from the quasar PDS 456. The findings are presented in a paper published March 25 on arXiv.org, in which the authors investigate the properties of this outflow. Powered by...
