Wow, and before you tell me the images are grainy, remember, this is from a probe we humans put around Saturn! Saturn’s northern and southern lights glow in red on the bottom and purple on top in visible light, according to Cassini photos.
Okay, this makes me mad.
This year marks 45 years since we put a human on the Moon, and 54 years since the first human orbited the Earth. How is this possible? In all my years of teaching, I have NEVER met a kid who thought the Sun went around the Earth, not one. Frankly, I doubt I’ve met many adults who thought that either (and like most folks, I’ve met some really dumb people). Anyone who doesn’t understand how the Earth orbits probably can’t blame it on our educational system. Certainly not in a state like Ohio where it has been taught since long before I was born. This is ignorance by choice.
The original press release is here…
Mars rover Curiosity snapped this photo of Earth (and the Moon) high in the Martian sky. You can see it much clearer in the larger size (click on the link). Humans can be amazing sometimes.
The BBC has created this infographic to illustrate some predictions on the far future. All the way to 100 trillion years from now. Not sure I buy a lot of it though.
Mass movement strikes! Amazingly, no one was hurt.

This visualization from NASA, shows yearly deviation in average temperature from a mid-twentieth century baseline. It shows 1950 to 2013.
Well, sort of, he says we got a few things wrong.
Hmmmm, jelly donuts on Mars, sign me up to go. Speaking of Mars, how did the rover that was to last only three months just keep going?
Water, water everywhere. Or so it seems.
Our weather word of the day.
This has long been suspected…
One of the oddest, most interesting characters in amateur science. He revolutionized home astronomy and taught thousands of people how to make powerful home telescopes, he died on January 15th at 98.

Finally, a cool image to get you thinking from Phil Platt. What would a lunar eclipse look like from the moon?
Thanks to Kai for the last one.
Well it looks like we’ll be seeing some truly cold weather as school starts back up. It’s summer in Antarctica right now, but it’s a good time to reflect on how cold it can get on our planet (remember, being in the Southern Hemisphere, their winter is during our summer). Few scientists can take wintering on the Antarctic continent. The population of the whole continent drops to only a few hundred over the winter and they must pass a rigorous screening process before they are allowed to do so. The video below shows what “Condition 1” weather is like. No travel outside quarters is permitted during these conditions.
Makes you feel warmer already, doesn’t it?
“The “Super Ball Bot”, under development at NASA Ames, is a robotic exoskeleton designed to land on the surface of Titan without a parachute or airbag.”
Since we have discussed this in Dynamic Earth, I came across this story and immediately thought, “Cave diving is crazy dangerous.”
According to Space.com
China has accomplished the first soft landing on the moon since 1976! They are only the third country to do so.
Update: The “Jade Rabbit” rover is sending back it’s first pictures…
Iran says they have launched a monkey into space, controversy ensues…
Getting closer and closer to finding remains of life of the Red Planet.
Well one hurdle won’t be quite as high as expected…
This has been expected for awhile based on computer models. Now we have evidence…
You tell ’em Bill!
ISON is gone, but Comet Lovejoy can be seen, but not without binoculars or a small telescope and clear skies….
If you were absent when we did the Virtual Earthquake Lab in Dynamic Earth you can make it up this week only! Here is the link…
NOTE: This lab requires that both Java is enabled on your browser and pop-ups are allowed for the website!
Select “Epicenter and Magnitude” a pop-up window should appear. Follow the instructions, the lab should take about 45 to 60 minutes to complete. If you are unsure how to complete and activity just click on the question mark and all will be explained. When completed take the quiz (there is no class code) and print the certificate with your results and bring it in. If you cannot complete the lab at home the computers in the media center are enabled to complete this lab.
ALSO NOTE: When entering the location of the epicenter in your journal, remember that longitude and latitude are divided into 60 minutes not decimals!
See me if you have any problems.
