Show Notes:

Why did we bring SciByte back?

Chris:

  • Too much out there is just plain distraction, why can’t we have our cake and eat it too? This is an important mission for us at Jupiter Broadcasting. We don’t want to offer only entertainment, but also information, news, and other things that just make you a treasure trove of small talk at your next cocktail party!
  • I almost see it as a public service too, this stuff is important and it impacts our entire universe!


Heather:

  • There are a lot of interesting things going on out there in science, but getting to the interesting bits without all the hype you get from major media outlets is a trick we are hoping to pull off.
  • The whole scientific method is about investigation and acquiring new knowledge to add to or correct old knowledge. We’ll provide you with enough knowledge to show off to friends and family and provide you the means, with the help of our trusty show notes, to further investigate the things that interest you the most.

Planet Mercury Full of Strange Surprises

  • The low down
    • The Messenger Spacecraft orbiting Mercury has completed it’s first Mercury day of orbit
    • That’s 176 Earth days, while Mercury’s years is a mere 88 Earth Days, that’s 2 years / day
    • The first 6 months of data was released including information on magnetic field, Mercury’s
      tenuous exoshpere, and surface composition
    • The surface composition of Mercury is different the other inner rocky planets
    • there are huge expanses of volcanic plain in the surrounding the noNorthern polar region
    • Evidence suggests that it formed during a different time than the other inner planets
    • There are also substantially hier amounts of sulfur and potassium than predicted (both vaporize at high temperatures, so extreme high-temperature events in it’s past are ruled out)
    • Scientists have also discovered vents, measuring up to 25 kilometers (km) (15.5 miles) in length, that appear to be the source of some of the tremendous volumes of very hot lava that have rushed out over the surface
  • Mercury has a weak magnetic field
  • Multimedia
  • Social Media

Looking back this week
Looking up this week
  • Keep an eye out for
    • This month Saturn sets just before Jupiter rises, and Venus is moving from the morning sky before dawn to the evening sky.
    • This month Jupiter is in opposition (opposite the sun to us), but it makes for good observations
    • Jupiter is roughly 45° up in the late evening skies to the East (height depends on where you are and what time your observing)
    • In the Pre-Dawn hours of the 20–22 you can see the Waning Moon in the SE about half way up the sky, along with the planet Mars
    • You might also be able to see a few Orionid metoers later this week in the SE skies as they peak in the Early morning hours of Saturday Oct 22, waiting till just after midnight might get you rates of up to 25 meteors per hour ( ~ 1/ 2.5 min )
    • The ROSAT X-ray observatory, launched in 1990 by NASA and managed for years by the German Aerospace Center (DLR), will re-enter the Earth’s atmosphere within the next two weeks. Current best estimates place the re-entry between Oct. 21st and 24th over an unknown part of Earth. (A Day before re-entry the estimate will be +/- 5 hours)
    • ROSAT re-entry page
    • Check the links for more information and updates, when and where you can see satellites going over head and even ongoing data updates on the chances of Aurora where you live
