“We have found a previously unrecognized class of spiral galaxies that are as luminous and massive as the biggest, brightest galaxies we know of,” said Patrick Ogle, an astrophysicist at the Infrared Processing and Analysis Center (IPAC) at the California Institute of Technology in Pasadena and lead author of a new paper on the findings…

Hubble spots strange spiral galaxy
Hubble captures image of spiral galaxy which exhibits rare behaviours Astronomers observed intense radio jets spewed from the galaxy’s centre The galaxy also has two more regions producing strong radio emissions Nasa says such activities have long been associated with elliptical galaxies The Hubble Space Telescope has spotted unusual behaviour in a constellation one…
Structures Size of the Earth’s Orbit Lurk in Milky Way’s ‘Atmosphere’
Astronomers got the first hints of mysterious objects 30 years ago when they saw radio waves from a bright, distant galaxy called a quasar varying wildly in strength. They figured out this behavior was the work of our Galaxy’s invisible ‘atmosphere’, a thin gas of electrically charged particles which fills the space between the stars….
Ancient Dwarf Galaxies Triggered the Universe
The green pea dwarf galaxy shown above “appears to be an excellent local analog of the numerous dwarf galaxies thought to be responsible for the reionization of the early universe,” said University of Virginia astronomer Trinh Thuan. “The finding is significant because it gives us a good place to look for probing the reionization phenomenon,…
Kepler’s ‘Bizarre’ Signal
The fascinating speculation surrounding a recent Kepler observation of a star 1,500 light-years away has reignited questions of alien life in our universe and what it means for future studies. ANALYSIS: Has Kepler Discovered an Alien Megastructure? First I really want to emphasize, as I did in my previous blog about KIC 8462852, that the…
High resolution far-infrared all-sky image
Far-infrared all-sky image observed by AKARI Represented as a two-color synthesis of blue: 90 micrometers and red: 140 micrometers. The Milky Way extends horizontally as the direction to the center of the Milky Way Galaxy is at the center of the image. The pale-colored, S-shaped part represents light from dust in the solar system. AKARI…
