NASA has just released a stunning new map of the heavens that
catalogs over 560 million objects captured by the Wide-field
Survey Explorer(WISE), NASA's infrared space telescope. Many of
the objects were first discovered by WISE as scientists studied
the 2.7 million images and 15 trillion bytes of data it
generated. The 2D map was ultimately created with 18,000 of the
images pieced together as a mosaic. In this view with we see
Milky Way Galaxy, shaped like a disk, running horizontally
through the middle. Our solar system is located about two-thirds
of the way out from the center of the disk. The survey was able
to capture so many new items in the sky because it used four
infrared wavelengths that are able to see the dimmest items in
the sky not visible to human eyes. Among the things the WISE
survey discovered were: Earth's "Trojan asteroid" —Trojan
asteroids share the same orbit as a planet. Mars, Jupiter and
Neptune all have them but Earth's was hidden for so long only
being visible in the daylight when vi
