Fast-moving debris from a supernova explosion triggered by a stellar collision crashes into gas thrown out earlier, and the shocks cause bright radio emission seen by the VLA. Credit: Bill Saxton, NRAO/AUI/NSF __________________________________________________________________________ Astronomers have found dramatic evidence that a black hole or neutron star spiraled its way into the core of a companion star and caused that companion to explode as a supernova. The astronomers were tipped off by data from the Very Large Array Sky Survey (VLASS), a multi-year project using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA). “Theorists had predicted that this could...

Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a "rogue," traveling through space unaccompanied by any parent star. "This object is right at the boundary between a planet and a brown dwarf, or 'failed star,' and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets," said Melodie Kao, who led this study while a graduate...

Astronomers have witnessed a key stage in the birth of a very heavy star, using two radio telescope views of the process taken 18 years apart. The young star is 4,200 light-years from Earth and appears to be surrounded by a doughnut-shaped cloud of dust.

never heard of ROK Navy's KVLS and KVLA? KVLS or Korean Vertical Launching Systme is indigenous,actually more like copy of Mk41,VLS for ROK Navy. KVLA or Korean Vertical Launching ASROC is indigenous Anti-Submarine Rocket that holds K745 Blue Shark LW torpedo. I gathered some rare pics of KVLS on the net. as always, I'm all thumbs when it comes to write in English. KVLSfor more KVLS info, visit the source URL. KVLA Red Shark and K745 Blue Shark LW torpedo
