Ophiuchus Constellation

twenty thousand light years far

is a Kepler’s Star sensation

unlike others, not bizarre,

.

recently observed by many

with unaided naked eye,

more completely seen than any

others in the Milky sky,

.

witnessed four hundred years ago

through Johannes Kepler’s view

in a vast supernova show

greater than sky watchers knew

.

at the time of first retrieving

these collected stars above.

Oh what marvels we’re perceiving

in the wondrous skies thereof!

NASA’s three Great Observatories -- the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory -- joined forces to probe the expanding remains of a supernova. Now known as Kepler’s supernova remnant, this object was first seen 400 years ago by sky watchers, including famous astronomer Johannes Kepler.

SN 1604

Constellation: Ophiuchus

Distance: 20,000 light years

RA: 17h 30m 42s

Dec: −21° 29′

SN 1604, also known as Kepler’s Supernova, Kepler’s Nova or Kepler’s Star, was a Type Ia supernova that occurred in the Milky Way, in the constellation Ophiuchus.

Appearing in 1604, it is the most recent supernova in the Milky Way galaxy to have been unquestionably observed by the naked eye.
