Lizard-Fish, Fungi, and Change

Image
We're learning more about why ichthyosaurs died out. Climate change was almost certainly involved: but it wasn't our fault, and I'll get back to that. Long before the first not-quite-an-ichthyosaur made the transition from land back to Earth's ocean, a tiny little fungus came ashore and started turning rock into soil.... ...First, though, my usual spiel about why I'm not upset that Earth isn't flat , Adam and Eve aren't German , and poetry isn't science ....

Seeking New Worlds, New Life - - -

Image
Analyzing what we've been learning about other planetary systems, some scientists say that maybe Earth is unusual, after all: maybe. Other scientists found another maybe-habitable planet less than 14 light-years away. Maybe planets like Earth are common: again, maybe.... ...I like living in a world where last year's list of known planetary systems is obsolete. Some folks don't. I'll talk about Copernicus and Sacred Scripture — right after my usual harangue about using our brains.... More at A Catholic Citizen in America .

Glyptodonts and Climate Change

Image
Climate change is in the news: again. Scientists tracked where tiny critters called phytoplankton have been living: which may help us understand what's happening in Earth's ocean. Other scientists reconstructed glyptodont DNA: confirming that the Volkswagen-size mammals were armadillos: big armadillos.... ...Being offended by our increasing knowledge of how this universe works is an option: but not a sensible one, I think. Neither is getting upset over what sort of creatures we are.... More at A Catholic Citizen in America .

Space Archaeologist, 55 Cancri e

Image
A headline, "TED 2016: Space archaeologist wins $1m to find hidden sites" caught my eye this week, and so did news about a very hot Super-Earth's atmosphere.... ...Science? In a 'religious' blog?? During Lent??! I don't see a problem with that. But as I keep saying — I think this universe is billions , not thousands, of years old; Earth isn't flat ; Adam and aren't German ; poetry isn't science ; and thinking is not a sin ....

Tiny Eyeballs and Purple Socks

Image
Some cyanobacteria — pond scum — swim toward brighter areas. Scientists didn't know how the microorganisms could tell where the light is, until now. Other scientists discovered four new species of an odd-looking sort of critter: including one that looks like a purple sock. I'm fascinated by this sort of thing, your experience may vary....

Luxembourg and Asteroid Mining

Image
Stories like " Rip Foster Rides the Gray Planet " and " Red Dwarf 's" Dave Lister singing "...Lived an old plutonium miner / And his daughter Clementine..." probably didn't help make asteroid mining seem like a serious idea. Then there's the 1966 Outer Space Treaty treaty: a tribute to the high ideals, and international politics, of the '60s. The idea was that anything we find outside Earth's atmosphere would belong to everyone. Nifty idea, not entirely wrong, and I'll get back to that. More at A Catholic Citizen in America .

Sleep and Being Human

Image
Humans sleep , which shouldn't be surprising. Just about all critters with brains sleep: mammals, birds, reptiles, amphibians, fish — even insects and nematodes experience something like sleep. Poets and playwrights have written of sleep.... More at A Catholic Citizen in America .

SETI: Looking for Neighbors

Image
Some scientist think globular clusters aren't good places to look for neighbors. Others took a fresh look at the data, crunched numbers, and pointed out that parts of globular clusters might be better spots for interstellar civilizations that the boonies where we live. Meanwhile, someone with a lot more money that I'll ever see decided to spend some of it on a systematic search for extraterrestrial intelligence. More at A Catholic Citizen in America .

Barsoom Development Ltd.

Image
The Curiosity Mars Rover sent a 'postcard' from Mars, a 360-degree view of dunes and a mountain in Gale Crater.... ...As usual, I'll ramble on about science, technology, and being human before getting to the interesting stuff: assuming that you think a robotic selfie from Mars is interesting. Not-entirely-as-usual, I wasn't finished rambling when I started the 'postcard' stuff, so this post has an afterword. I've done that before.... More at A Catholic Citizen in America .

On Mars by 2040?

Image
Robots have orbited Mars, landed there, driven around, taken pictures, and studied Martian rocks. But humanity's exploration of Mars has been by proxy: Nobody's gotten farther from Earth than Lunar orbit. That could change before 2040. NASA has worked out a step-by-step plan for getting humans back into deep space: provided that Congress doesn't change its mind. Even if that happens, my guess is that it wouldn't be long before someone else decides that people should act like humans.... More at A Catholic Citizen in America .

SpaceX, Mars, and Someday the Stars

Image
First of all: Merry Christmas! I'll have something more seasonally-appropriate ready by Sunday. That's the plan, at least. Today I'll be talking about spaceships, practical and otherwise: and why NASA cancelled InSight's March 2016 launch.... ...Instead of trying to analyze the reasons, I'll just get started with the December 1938 issue of Amazing Stories, Columbus, Robert Goddard, the Hanseatic League, and why airlines don't use disposable airplanes — not necessarily in that order....

Enceladus and Kepler’s Planets

Image
Scientists following up on Kepler observations learned that a bit over half of the objects tentatively identified as giant planets are brown dwarfs or stars. We've also learned that Saturn's moon Enceladus has a vast ocean under its icy surface: with all the ingredients needed for life.... ...If you've read my 'science' posts before, you know why I think Earth isn't flat ; the universe is billions , not thousands, of years old; poetry isn't science ; and thinking is not a sin ....

Ceres, Pluto: There’s More to Learn

Image
That's part of a picture from New Horizons: a sample from the highest-resolution images the spacecraft has started sending back. We're pretty sure that the mountains are frozen water, and the flat parts softer "ice:" probably including frozen nitrogen. The first journal paper using New Horizons' flyby data was published in October: but there's a great deal left to study, and even more still stored on New Horizons. ( November 13, 2015 ) Other scientists think they've found evidence that those bright spots in Occator Crater are frozen water, exposed when something hit Ceres. If they're right, the impact(s) happened recently. I'll get back to that. More at A Catholic Citizen in America .

Climate Summit: Costumes and a Smog Brick

Image
Climate change talks in Paris started this week, with the usual protesters and editorials. Meanwhile, folks in Minnesota are shopping at Christmas tree farms: and a performance artist in Beijing made a brick from smog.... ...I'm convinced that climate change happens: and has been happening since before life began on Earth, 3,800,000,000 or so years back. As I've said before, the natural world got along fine without us. Now that we're here, however, we're responsible for its maintenance.... More at A Catholic Citizen in America .

Mutant Medflies, GMO Mosquitoes

Image
First, the good news: releasing genetically-modified medflies and mosquitoes may mean fewer crop failures; and fewer deaths from malaria. Now, the not-so-good news: I'm pretty sure some folks won't think it's good news.... More at A Catholic Citizen in America .

Europe’s Complex Heritage

Image
I stopped using the term " Caucasian " several years ago. I've discussed the "Anglo-Teutonic" race, Neanderthals, and getting a grip, before. ( September 25, 2015 ; October 31, 2014 ) Turns out, folks from the Caucasus moved into Europe at least once — along with many other folks.... We're still learning about humanity's family history. It's a lot more complicated than we thought.... More at A Catholic Citizen in America .

Pluto’s Cup-Capped Mountains

Image
Before the New Horizons mission, we knew Pluto was very cold, had little or no atmosphere, and that was about it. ( October 30, 2015 ; July 10, 2015 ) Now scientists think they've spotted 'ice volcanoes' on Pluto that look a lot like shield volcanoes on Earth and Mars.... ...we're rational creatures, created in the image of God, and "little less than a god." Studying this universe, and using that knowledge is part of our job. So is using our power responsibly.... More at A Catholic Citizen in America .

Chimps, Apples; and Goggle Eyes

Image
Scientists may have observed chimpanzees in different groups using a different sound when they mean "apple." Then again, maybe not. Either way, we're learning more about chimpanzees. Pliobates cataloniae, an ape that lived where Catalonia is now, had a gibbon-like skull: but apparently is more closely related to today's gorillas, chimps, orangutans — and us.

Kerberos, Mars: Answers Raise New Questions

Image
Images sent back from New Horizons gave scientists their first opportunity to see how big Kerberos is. It's much smaller than they expected, which raises new questions. Meanwhile, the Mars Reconnaissance Orbiter's instruments provided evidence that there's running water on Mars: every summer, on some crater slopes. It's not the Mars of Burroughs' Barsoom tales: but I think the planet is getting more interesting, the more we learn about it. More at A Catholic Citizen in America .

The Halloween Asteroid: 2015 TB145

Image
(From Alex Alishevskikh, cyberborean.org; via Flikr and Space.com, used w/o permission.) (" Trail of the object that exploded over Chelyabinsk, Russia, in 2013. " (Space.com)) Asteroid 2015 TB 145 won't hit Earth, but it will be only slightly farther from us than the Moon at 1:05 p.m. EDT, 5:05 p.m. UTC, October 31. I've talked about asteroids, Earth Time, and why thinking ahead makes sense, before.... ...Fifty years ago, we probably wouldn't have noticed an incoming asteroid until very shortly before it hit. Even if we did, there wouldn't have been much we could do, apart from praying — and that's another topic.... More at More at A Catholic Citizen in America .
