Scientists detect biggest explosion since Big Bang

Technology
The biggest explosion in the universe since the Big Bang has been discovered by astronomers.The blast came from a supermassive black hole in the Ophiuchus galaxy cluster about 390 million light years from Earth. Scientists say it released five times more energy than anything witnessed before and left a giant dent in the galaxy cluster.Professor Melanie Johnston-Hollitt, from the International Centre for Radio Astronomy Research, said: "This is the most energetic outburst we have seen since the Big Bang."We've seen outbursts in the centres of galaxies before but this one is really, really massive. ...

Telescopes detect ‘biggest explosion since Big Bang’

Science
Scientists have detected evidence of a colossal explosion in space - five times bigger than anything observed before. The huge release of energy is thought to have emanated from a supermassive black hole some 390 million light years from Earth.The eruption is said to have left a giant dent in the Ophiuchus galaxy cluster.Researchers reported their findings in The Astrophysical Journal."I've tried to put this explosion into human terms and it's really, really difficult," co-author Melanie Johnston-Hollitt told BBC News. "The best I can do is tell you that if this explosion continued to occur over the 240 million years of the outburst - which it probably didn't, but anyway - it'd be like setting off 20 billion, billion megaton TNT...
SpaceX enjoys test-fire success – months after launchpad explosion

SpaceX enjoys test-fire success – months after launchpad explosion

Technology
SpaceX has finally successfully completed a static test fire of its Crew Dragon spacecraft, following an explosive failure earlier this year.The Crew Dragon is intended to fly astronauts to the International Space Station, but "a series of engine tests" in Cape Canaveral, Florida, earlier this year threatened those ambitions. "The initial tests completed successfully but the final test resulted in an anomaly on the test stand," was the company's statement at the time, after a leaked video appeared to show the spacecraft exploding in flames.

The methane-filled lakes on Saturn’s moon Titan are explosion craters, model predicts

The methane-filled lakes on Saturn’s moon Titan are explosion craters, model predicts

Science
Sept. 9 (UPI) -- According to a new model developed by planetary scientists in Italy and the United States, many of the methane-filled lakes on Titan were likely formed after explosions of warming nitrogen left dozens of empty craters dotting the surface of Saturn's largest moon. Outside of Earth, Titan is the only planetary body in the solar system known to host stable liquid on its surface. While Earth hosts bodies of water, Titan's lakes are filled with liquid methane and ethane. On Earth, methane and ethane typically exist in gas form, but subzero temperatures on Titan allow the hydrocarbons to exist in liquid form. Previous models suggested Titan's lakes were formed over thousands of years as the liquid methane and ethane precipitated by Titan's clouds dissolving the moon's bedrock ...
Astronomers find white dwarf merger that may spawn future fiery explosion

Astronomers find white dwarf merger that may spawn future fiery explosion

Science
May 21 (UPI) -- Astronomers have discovered a rare celestial object. Scientists suggest the fiery orb was created when two dead white dwarfs merged and become reanimated. According to a new paper describing the unusual stellar object, published this week in the journal Nature, the orb is a ticking time bomb -- likely to explode with a fiery bang in the near future. Scientists first spotted the object while analyzing data collected by the Wide-field Infrared Survey Explorer, or WISE, satellite. Astronomers spotted a bright star at the center of a gas nebula, but were surprised to find no visible light, only infrared radiation, emanating from the nebula. When astronomers analyzed the spectrum emitted by the nebula and its central star, they determined the object contained neither hydrogen ...
