Ring-like Structure tagged posts

Researchers from Kobe University and the National Institute of Technology, Oshima College have conducted a detailed reanalysis of image data from Voyager 1, 2 and Galileo spacecraft in order to investigate the orientation and distribution of the ancient tectonic troughs found on Jupiter’s moon Ganymede. They discovered that these troughs are concentrically distributed across almost the entire surface of the satellite. This global distribution indicates that these troughs may be actually part of one giant crater covering Ganymede.

Based on the results of a computer simulation conducted using the “PC Cluster” at the National Astronomical Observatory of Japan (NAOJ), it is speculated that this giant crater could have resulted from the impact o...

5 billion light years is a distance almost inconceivable, even on a cosmic scale ie 35,000 galaxies the size of our Milky Way are needed to cover that distance. Hungarian-U.S. team have now found a structure this big really exists in the observable universe.

The researchers found a ring of 9 gamma ray bursts (GRBs)—the most luminous events in the universe—5B light yrs in diameter, and having a nearly regular circular shape, with a 1 in 20,000 probability of the GRBs being in this distribution by chance...
