SPACE FORENSICS: Death of a Star Sara Mitchell Jim Lochner NASA Goddard Space Flight Center Greenbelt, Maryland

What’s a supernova?

Can you spot the supernova?

Supernova Timeline Earliest recorded supernova — 185 A.D. in China Famous historic supernovae in 1006, 1572, and 1604 A.D. First telescope built in 1608 by Hans Lippershey Multiwavelength observations of supernova remnants began in 1937

Beginning the Investigation What do we want to know ?

Case File: Cassiopeia A Host Galaxy: Milky Way Constellation: Cassiopeia Galactic Coordinates: G Distance: ~ 10,000 light years Discovery: 1947 Interesting facts: Discovered by radio observation Strongest radio source in the sky beyond our solar system Image: Chandra X-Ray Observatory August 19, 1999

Crime Scene Photographs VisibleX-RayRadioInfrared Hot gas (50 million degrees) Clumps of matter (10,000 degrees) Dust grains (several hundred degrees) Spiraling high energy electrons

Why Multiwavelength?

Supernova “DNA”

“Signature” Spectroscopy

Looking for Signatures All X-Ray Energies Calcium Silicon Iron

Case Closed? Have we answered all of our questions? Have we found new questions? Where else can we find answers? What could we learn from seeing a “live” supernova?
