I really need to start doing this.
An ancient supernova mystery finally solved
This image combines data from four different space telescopes to create a multi-wavelength view of all that remains of the oldest documented example of a supernova, RCW 86. The Chinese witnessed the event in 185 A.D., documenting a mysterious “guest star” that remained in the sky for eight months.
X-ray images from the XMM-Newton and Chandra are combined to form the blue and green colors in the image: interstellar gas that has been heated to millions of degrees by the passage of the shock wave from the supernova. Infrared data from Spitzer and WISE are shown in yellow and red, and reveal dust radiating at a temperature of several hundred degrees below zero, warm by comparison to normal dust in our Milky Way galaxy.
The cause of the explosion witnessed nearly 2,000 years ago was a Type Ia supernova, in which a white dwarf was pushed beyond the brink of stability when a companion star dumped material onto it. By blowing a wind prior to exploding, the white dwarf was able to clear out a huge “cavity,” a region of very low-density surrounding the system. The explosion into this cavity was able to expand much faster than it otherwise would have.
This is the first time that this type of cavity has been seen around a white dwarf system prior to explosion. RCW 86 is approximately 8,000 light-years away in the Circinus constellation. At about 85 light-years in diameter, it occupies a region of the sky that is slightly larger than the full moon.
This is preety legit
my halloween costume this year ahahah
