Saturn’s Moons And Rings Are Like An Antique Shop – The Daily Orbit
What’s up with this chilly spring? Why isn’t it warmer?
Move over Siri there’s a more emotionally available chick in town.
What set the world on fire?
And it’s an antiques road show on the Daily Orbit!
Hello and welcome to the Daily Orbit. I’m Emerald Robinson.
Talk about an antiques road show! How about an antiques solar system show? Cassini scientists say that Saturn’s moons and rings are gently worn, vintage goods from around the time of our solar system’s birth. They say they date back more than 4 billion years, and that studying this system helps us understand “the chemical and physical evolution of our entire solar system.” Astronomers say that they must study all the rings and moons to understand the evolution of the Saturnian system, specifically whether the rings formed out of the debris from Saturn’s moons or vice versa. Saturn’s Antiques—that sounds like a good set up for the Solar System Pickers.
Okay I’m ready to ditch the coat for warm weather! So the groundhog lied to us, because spring sure hasn’t been anywhere in sight. According to climate scientists, with the melting of the arctic ice, not only comes hotter summers but colder winters as the reduction in sea ice affects jet steam activity. The westerly jet stream now slowly meanders instead of moving directly and quickly, transporting less warm air during winter. Scientists say to expect more extreme weather events like heavy snowfall, heat waves, and flooding. Is it just me, but shouldn’t global warming insinuate –WARMING?
I’m sorry Siri but, I’m happy to introduce a soon to be new smartphone personal assistant—Zoe! Zoe is a virtual “talking head” that is capable of expressing human emotions on demand and may replace text messaging with “face messaging.” And this is really cool, you will be able to upload your own face and voice to customize your own Zoe…or in my case, Emerald. So when I text my boyfriend “I’m fine!” my avatar can show what I’m really feeling. This should really help out all you clueless dudes out there.
“We didn’t start the fire!” Well Billy Joel was right. A new study is hypothesizing that the asteroid that slammed into a region of Mexico known as the Chicxulub Crater could have triggered a global firestorm, burning every twig and blade of grass, and wiping out 80% of all species. Using a new model, the team showed how a collision would have vaporized huge amounts of rock that were then blown high above Earth’s atmosphere. As it re-entered, the material would have created a boiler effect heating up the atmosphere to a scorching 2700 F for several hours, killing everything above ground. The lead researcher said, “If a person was on Earth back then, it would have been like sitting in a broiler oven for two or three hours.” Ouch.
So does this next study mean we humans used to have bulging eyes? A new study says that tarsiers’ bulging eyes shed some light on the evolution of human vision. This interesting little elf-looking primate split ways early on with monkeys, apes, and, well humans. New genetic research of these little primates challenges the prevailing view that the switch to three-color vision happened only after primates switched from nighttime to daytime living, and instead suggests the ability to see in three colors developed while the creatures were still nocturnal. Studying the genes of the tarsier, scientists say this ability would have helped in dim light levels, such as twilight or bright moonlight. They say that our human ancestors developed vision in the same way allowing us to emerge from the shadows.
Well, that’s it for the Daily Orbit!
