Death Stars – IOTW Report

Death Stars

Courthouse News

A pair of dead stars locked in a slow spiral toward mutual destruction has been discovered just 150 light years from Earth — the closest system of its kind ever found.

The discovery, published Monday in the journal Nature Astronomy, comes from a team of astronomers at the University of Warwick who identified a massive, compact pair of white dwarfs — dense stellar remnants that are the end stage of a star’s life. These two white dwarfs are expected to collide and explode in a type 1a supernova, one of the brightest and most important types of cosmic explosions.

The system is the first confirmed double white dwarf pair in our galaxy that scientists believe will eventually explode as a type 1a supernova. Researchers say it’s also the heaviest of its kind ever recorded, with a combined mass of 1.56 times that of the sun. More

  1. @Dr. Tar — Good question. I’m glad we’ll not be around to find out.

    My AI (Aria in the Opera browser) says that this kind of supernova would be dangerous at 50 light years, but not 150.

  2. What we want to do here at NASA is to send an un-crewed probe to these dead stars to get some videos and data of the big smash-up.

    OK, 150 years to get there, 150 years to observe, and 150 years to report back, assuming we can travel at the speed of light, which should be possible by next August.

    In 450 years we’ll get the video. Be patient.

  3. MSNBC, CNN, The Guardian, and AP all report that the colliding dead stars will destroy life on earth.

    The Oxford Union of Concerned Scientists said: Dr. Hawking said five years ago that humans have to get off the earth within one hundred years. Well, that’s down to 95 years now. All the governments of the world must unite to meet this challenge. Our mantra is: At all costs we must get off. NOW!
