Kepler’s Supernova with all three of NASA’s Great Observatories
•Just 400
years ago: (Oct. 9, 1604)
•Then a
bright, naked eye object
(no telescopes)
•It’s still
blowing up – now 14
light years wide and expanding
at 4 million mph.
•There’s
material there at MANY
temperatures, so many
wavelengths are needed
to understand it.
