Jezero Sediment, TOI-715 b: Headlines and Extraterrestrial Life

Image
Last month ended with headlines hinting that our first glimpse of extraterrestrial life was just around the corner. " Discovery Alert: A ‘Super-Earth’ in the Habitable Zone " Pat Brennan, NASA News (January 31, 2024) " Scientists More Hopeful Than Ever That Perseverance Has Already Found Life on Mars " Carly Cassella, ScienceAlert (January 24, 2024) A week later, there's the usual politics and pandemonium in the news: but no space aliens. I'm not surprised. I'm not disappointed, either. I am, however, excited about what we've found in Jezero crater, and a new world that's not quite Earth 2.0.

Silly Headlines and Space Aliens, Serious Science and UAPs

Monday, I wondered what I was going to write about this week. Then I read that scientists found methane and carbon dioxide in a not-really-Earth-like planet's atmosphere — and saw a silly headline or two.... ...Anyway, K2-18's atmosphere is mostly on hold for now. Instead, I'll talk about (alleged) space alien bodies, Nazca Lines and (human) mummies. And I'll take a look at NASA's UAP report. A quick look. It's been one of those weeks.

NASA, UAPs, UFOs and a Bart Simpson Balloon

It's been two and a half weeks since NASA's "Public Meeting on Unidentified Anomalous Phenomena", aired on YouTube. Or is that streamed on YouTube? Never mind. The NASA panelists did not announce contact with an extraterrestrial diplomat, or admit that they've been holding space aliens captive. So some of the folks who were contributing to the video's live chat were profoundly disappointed. The panelists did, however, discuss what Unidentified Anomalous Phenomena (UAP) means, how they'll be collecting and analyzing data, and answered some questions. Ideally, I'd have listened to all four hours of the meeting, pondered its content, and would now be sharing the highlights. That didn't happen. But I did catch bits and pieces of the video: mostly during the last hour. So I'll be talking about that today, focusing on a former pilot and astronaut's experience: along with flying saucers, ball lightning and (very briefly) space aliens.

Super-Duper Super Earths and the Search for Life

TThis week, I'll talk about Professor Ethan Siegel's view that "the myth of the super-habitable super-Earth planet" is "a scientific catastrophe", other non-catastrophes; and a problem with "super-Earths" as a label. Along the way I'll look at science, news, headlines and silliness. And finally, skip lightly over a 13th century academic debate that got out of hand. "...A Scientific Catastrophe"? Earth ISN'T the Best of All Possible Worlds???

Exoplanets, Dust, and Who Sees Data First?

Image
It's been a little over 10 years since scientists spotted Kepler-22 b. It was the first time we'd spotted a transiting exoplanet that's in its sun's habitable zone. That may or may not mean that Kepler-22 b is habitable. The odds are good that the exoplanet is a water world: covered with an ocean far deeper than Earth's Since then we've discovered quite a few water worlds. And, possibly because there's a 1995 action film called "Waterworld", they're often called ocean worlds. 1 This week I'll talk about two (probably) ocean worlds, Kepler-138 c and d; discovered in 2014, they're far to hot for life as we know it. But scientists recently published a new analysis of those two worlds. And that gave me something to talk about. So did a proposed change in when taxpayer-funded research projects release data. It's good news or bad news, depending on who's talking. That's this week's first item. I'll also look at

Mars, MOXIE and More

Image
Humanity is one step closer to exploring Mars, in person. With people living and working on the surface. And eventually, I think, living there permanently That's going to take time. But like I said, we're one step closer. This week I'll be talking about In Situ Resource Utilization (ISRU), the NASA-ESA Sample Return Mission, and why we're keeping our spaceships clean. Until they land, at any rate. More at A Catholic Citizen in America . (Oxygen production on Mars test succeeds. MOXIE broke its old record. ISRU, living off the land on other worlds; and plans for Mars sample return.)

Exploring Mars, Looking for Life: and Still Learning

Mars is and will be in the news this month. The UAE Hope spacecraft settled into orbit around Mars Tuesday, February 9. Then, a day later, China's Tianwen-1 arrived.... ...The UAE's successful orbiter is historically significant. And China's Tianwen-1 may collect useful data. But I'll be focusing on the NASA mission. And Mars.... More at A Catholic Citizen in America .

Seeking Strange New Worlds, Life and Civilizations

I noticed "Research sheds new light on intelligent life existing across the galaxy" in last year's science news headlines. That, and "'Mirror Image' of the Earth and Sun Discovered 3000 Light-Years Away," started me writing about exoplanets, SETI and vaguely-related topics. About 8,400 words later.... ...So I saved what I'd written and proceeded with reading, writing and not going bonkers during an election-year pandemic. Some of the "...sheds new light..." material went into "My Top 10 Science News Stories For 2020." Most of it will (probably) go into this series. More at A Catholic Citizen in America .

My Top 10 Science News Stories For 2020

Image
I'm seeing "The Best of," "Top 10" and "2020 Top" headlines in my news feed: as usual for late December. Instead of waiting for someone else to highlight this year's science news stories, I'm making my own 'top 10' list. Each item is something that caught my attention, seemed important, or has been lurking in my 'to do' folders. More at A Catholic Citizen in America .
