This is the week right before spring break, so I’ve fallen behind a bit in posting while I was distracted by writing a few exams. I’m going to India starting on Saturday, so I hopefully can catch up (if not get a bit ahead!) this week.
- we started talking about impact craters this week, which led one student to highlighting a NY Daily News article about Asteroid 2011AG5 — the first line reads “Calling Bruce Willis!” to give you a hint as to the slant… (the Discovery News article is less inflammatory)
- Cassini images reveal that Titan may have seasons, which cause cloud fluctuation, as well as day to night temperature differences
- a change in the magnetic field last week in conjunction with the high solar flare activity caused some impressive northern lights (the pictures with the article are well worth clicking through for)
- computer modeling of how the northern lights behave was also featured in Discovery News this week
- discussions about the future of space travel are still cropping up — the most recent from Discovery News
- because we were also discussing volcanoes, one student found an article about a recent Hawaiian eruption of “Pele’s braids” (which I could not find a reference to in my quick & dirty search of my volcano books and reputable internet sites)
(The impact story was popular as was the Titan story–both had multiple summaries.)
I should get the my physical geology’s summary up later today.
