Rare red nova explosion could add a star to the sky in 2022
There is much still to learn about the universe, and red novas remain one of its mysteries. It's thought these explosive events, named for their red glow, are the result of binary stars finally merging after eons of cosmic courting. That's the prevailing theory, anyway, but the rare event has only been observed a handful of times. Our understanding of this stellar event, as well as the lifecycle of stars in general, could improve significantly if the prediction of Calvin College astronomer Larry Molnar proves true. He believes he's spotted a duo of stars that are on the cusp of merging, becoming a red nova in 2022, "give or take a year." It's not just exciting for the research community, though, as the explosion should be so energetic that we'll be able to see it in the night sky with the naked eye.
Calvin College duo creates cheap, portable supercomputer
Just months after scientists were able to run a quantum computer simulation on an everyday PC, we're now hearing that a Calvin College student / professor tandem have created an inexpensive, portable supercomputer for crunching massive chunks of data on the go (and on the cheap). Dubbed Microwulf, the wee beast is hailed as a "machine that is among the smallest and least expensive supercomputers on the planet," and when not being checked as baggage on a flight, can reportedly process 26.25 gigaflops of data per second. The system itself touts "four dual-core motherboards connected by an eight-port gigabit Ethernet switch," and when initially constructed, it cost just $2,470 to build. Talk about a solid price-to-performance ratio.[Via Slashdot]
