A new photo of NGC 4254, or Messier 99, was captured by the European Southern Observatory’s Very Large Telescope. It is a grand design spiral galaxy, whose spiral arms wrap tightly around the galaxy’s center. The golden spiral arms of a distant galaxy sparkle in...

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...

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...

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...

Three dozen dwarf galaxies far from each other had a simultaneous ‘baby boom’ of new stars, an unexpected discovery that challenges current theories on how galaxies grow and may enhance our understanding of the universe. Galaxies more than 1 million light-years apart should have completely...

This star-studded image shows the irregular dwarf galaxy Sextans B, which lies around 4.5 million light-years from Earth at the outermost edges of the Local Group. With a total mass of around 200 million times the mass of the Sun, Sextans B hosts an intriguing...

A STUNNING image of our Milky Way galaxy shining brightly over a medieval castle has been snapped in Dorset. Photographer Graham Hunt captured Corfe Castle surrounded by a thick sea of mist on a cold and clear night on Monday. The stars of the Milky...

The Whirlpool Galaxy sounds like a horror movie. In space, no one can hear you scream, but on Earth we have ways of turning space objects into haunting soundtracks. Galaxies, black holes and nebulae come to life via audio, giving us a new way to...

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....

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...
