Hey, everyone! If you look up at the right time, you can…
Uh. Yeah, anyway.

Yet another conjunction of the Moon, Mars, and, uh…

A sneak peek at the inside of the Red Planet
December 18, 2020
Despite the lack of large marsquakes, the researchers were able to estimate how thick Mars’ crust is. They predict it has three layers—but possibly two—that are between 12.4 and 23 miles thick, reports Nature. Mars’ crust is considerably thinner than that of Earth, which can be up to 25 miles thick—and that’s surprising, reports Science.

Lots of small “Marsquakes,” but nothing big. Max M4.5.
A techtonically silent world. Might explain the weak magnetic field which allowed solar winds to rip off its atmosphere long ago.
Remember the Titan! Uh. The moon. Called Titan.

Cyclopropenylidene is the second cyclic or closed-loop molecule detected at Titan; the first was benzene in 2003. Benzene is an organic chemical compound composed of carbon and hydrogen atoms…Cyclic molecules are crucial because they form the backbone rings for the nucleobases of DNA, according to NASA.

The only moon in the solar system that has an atmosphere…4 times denser than the Earth, actually.
Except it rains ethane and methane and is -270C. Not exactly a place to plan a vacation.
But the organic molecules may (BIG may) hint at life of some sort.
And we only have to wait until 2034 to find out!

Thank you to my new followers – drop me a line!

Dropping a shoutout to all my followers, old and new. Thanks for reading!
I’m preparing this week’s installment of Bringer of Light (Chapter 3, Part 2), all the while scouring the web for science and tech news to share.
Anything you want to see shared (or want to share)? Comments on the story so far? Something you want to rant about? (No politics please! Waaay too much of that at home right now. I’d rather keep my head in the stars when possible…)
Bringer of Light: Chapter 3, Part 2 – dropping at 7 p.m. EDT October 31st. No Halloween theme, sorry (that’s a separate post 🎃).
Wishing our base away…water on the Moon?
October 26, 2020
The new research is especially topical given that NASA plans to land humans on the Moon in the 2020s and use lunar resources as part of its Artemis program, prompting thorny discussions about legal and ethical extraction of materials on the Moon.

“Micro cold traps.” The equivalent of a 12-ounce bottle in a cubic meter of soil. But not everywhere, and primarily at the polar caps.
So…how will this help, exactly? 🤔

“The spacecraft did everything it was supposed to do.”

Um. OK. That’s some confidence in your own project you got there, dude.
Now all we have to do is wait a couple of weeks to find out if it actually grabbed anything!
Hey, Bennu, gimme a “High-Five”!
October 20, 2020
Researchers understand it to be what they call a carbonaceous asteroid, meaning its rocks still retain a lot of the chemistry that was present when the Sun and the planets came into being more than 4.5 billion years ago. Hence the desire to bring some of its material home for analysis in sophisticated Earth laboratories.

If it’s a spinning top, I don’t see how showing it in comparison to the Eiffel Tower will help us understand how big it is…
Then again, usually media compare things like this to a football field (US) or a football pitch (UK). Or they say things like “as long as [insert type of moving vehicle here] end to end.”
Honestly, just say “510 m3” and leave it at that. All we care about is what the probe will do: Vacuum up and bring back at least 60g of materials from the beginning of the solar system.
Now how about THAT, Hayabusa-2?
Get your telescopes out, the solar system’s largest volcano is here!
October 9, 2020
The volcano is about the size of Arizona with a volume 100 times larger than that of Mauna Loa’s, Earth’s largest volcano, NASA says. “In fact, the entire chain of Hawaiian islands (from Kauai to Hawaii) would fit inside Olympus Mons!”
Brighter than Jupiter this October! And the closest Mars will be until 2035.

“Weird space” beyond the heliosphere
October 3, 2020
“When you look at different parts of the electromagnetic spectrum, that area of space is very different from the blackness we perceive with our eyes,” says Michele Bannister, an astronomer at the University of Canterbury in Christchurch, New Zealand, who studies the outer reaches of the Solar System. “Magnetic fields are fighting and pushing and tied up with each other. The image you should have is like the plunge pool under Niagara Falls.”
Ever wondered what a lunar eclipse on Mars looks like?
