  • READY JET GO! is a PBS KIDS earth science and astronomy series for children ages 3-8. The series follows two neighborhood kids: Sean, who has an all-consuming drive for science facts, and Sydney, who has a passion for science fiction and imagination. They both befriend the new kid on their street, Jet Propulsion, whose family members happen to be aliens from the planet Bortron 7. Catch this great new science based show for kids week days at 2:30 pm.
  • Looking up, this week’s sky highlights: Sky & Telescope’s weekly observing charts, where to find Jupiter, Mars, and Saturn. Jupiter is at opposition, good time to point your telescopes at it.Dusk March 4

  • New observations from the Hubble Space Telescope are helping characterize the atmospheres of exotic exoplanets. Theory says that the super-Earth 55 Cancri e contains crystallized carbon in its interior, earning it the nickname “diamond planet.” Theory also says that on the hot, young super-Jupiter 2M1207, rain could be made of vaporized rocks, silicates as fine as cigarette smoke particles.  Deeper within its atmosphere, that rain may turn to iron sleet.  Read more from Sky & Tel website.

    It’s possible that Charon once had a subsurface ocean that has long since frozen and expanded. Read more from Astronomy website.

Pluto and Charon

The New Horizons spacecraft captured Pluto rotating over the course of a full “Pluto day.

In July 2015, the cameras on NASA's New Horizons spacecraft captured Pluto rotating over the course of a full "Pluto day." The best available images of each side of Pluto taken during approach have been combined to create this view of a full rotation.

Postcards from Pluto

The downloading of images from the New Horizons spacecraft began over the Labour Day weekend.

The detail is incredible, click on this image of Charon. you won’t believe the resolution.  The smallest visible charon-9-10-15feature is just a bit under 5km in size.

” Images downlinked in the past few days have more than doubled the amount of Pluto’s surface seen at resolutions as good as 400 meters (440 yards) per pixel. They reveal new features as diverse as possible dunes, nitrogen ice flows that apparently oozed out of mountainous regions onto plains, and even networks of valleys that may have been carved by material flowing over Pluto’s surface. They also show large regions that display chaotically jumbled mountains reminiscent of disrupted terrains on Jupiter’s icy moon Europa.”
