“For the first time ever, humanity has changed the orbit of a planetary body,” said NASA planetary science division director Lori Glaze.

A change of 32 minutes in orbit — but only 4% of the total orbital period. To deflect an asteroid away from Earth, it’d better be done several years in advance. 🌏
Still, it can be done. An amazing first.

I should be posting another chapter from Bringer of Light, but I don’t feel like writing that right now, what with a humongoid typhoon slowing churning its way here.
So here’s an article about what Chinese scientists found in Moon dirt.
Also H3. Yay. Let’s make fusion reactors and walk on the Moon together…

Our search for alien life is getting serious. With better telescopes and a growing scientific consensus that we’re probably not alone in the universe, we’re beginning to look farther and wider across the vastness of space for evidence of extraterrestrials.
But it’s possible we’re looking for too few signs in too few places. Having evolved on Earth, surrounded by Earth life, we assume alien life would look and behave like terrestrial life.

I agree that we are biased, simply based on the basics of what we understand as (carbon-based) life (i.e., ourselves).
And I agree — in principle — that scientists need to keep an open mind when looking for other life forms on exoplanets.
However, they also need to retain a sense of skepticism.

These aren’t the drones that deliver your online order. Loaded with cameras, sensors, and explosives, their mission is to drive themselves to a target with an algorithm in the driver’s seat. They destroy themselves along with the target, leaving behind just a pile of electronic detritus.

Oh, joy. I can’t wait to see what happens when we program 3D printers to churn them out.
Or just simply make them self-replicating. What could possibly go wrong?

The samples were extremely hydrophobic, and repelled water as if it were the most disgusting thing ever invented. Researchers labored to get the lunar soil to gradually soak up water. They also added a nutrient solution.

Turns out that it is possible to grow plants on the Moon…
…although you might want to wear gloves while farming, since the “soil” contains tiny pieces of glass from constant bombardment.

…if you are lucky enough to live Western Europe, parts of northwestern Africa, and some of the Americans…
As for why the Moon appears red…
“You’ll actually be seeing every sunrise and every sunset occurring around the Earth at once. All of that light will be projected on to the Moon.” (Dr Gregory Brown, Royal Observatory

And if you happened to be standing on the Moon at the time, you’d see a blood ring encircling the Earth in front of you (ah, assuming you were not on the other side of the Moon).
Come on. Somebody has got to figure out how to get a picture of that.

Right. So I quit Facebrat a couple years ago after I got fed up with the self-righteous, arrogant attitude of its founder Mark Zuckerberg and its blatant stealing and selling of personal information of its users.
And also because I was wasting hours and hours each week reading meaningless Facebark posts on my smartphone (so I deleted the app, which I strongly recommend you all do to prevent the company from tracking your location, then selling that info to the spam industry…although you’re probably going to be tracked via BlueTooth anyway if you keep it on).
But after my mother passed away, and while I was still away from family, friends, and colleagues and living in Montréal, I couldn’t take the isolation.
And also a teacher’s group based at the McGill University (William Shatner’s alma mater!) named BILD asked me to join a FB Group.
So I rejoined and vowed to avoid posting anything about religion and politics, and to focus on the things that matter – food, family, and occasional humorous events.
Until I foolishly wrote a casual comment on my brother’s post:

(Note: You won’t be able to see the planets actually looking like these photoshopped images…unless you happen to have a really powerful telescope in your backyard.)
Not sure why I first got this info from a site based in New Jersey. The info about what time of day and in what part of the sky is only relevant to people living in the NJ_NYC area.
Still, it’s an interesting phenomenon that occurs once every few years…
2005. 2016. 2020. And 2022. Not exactly a regular pattern, it seems.
And, no, there is no “spiritual significance” to a planetary alignment. It’s an illusion, an imaginary lining up of the solar system that doesn’t affect you personally. Sorry.
But it’s still fun to watch. Er, if you enjoy getting up before dawn (I don’t).
According to nj.com, “The planetary parade of sorts will occur when Jupiter, Venus, Mars and Saturn all appear to be lined up in a row above the horizon during the pre-dawn hours — starting Saturday morning, April 23. The alignment will also be visible during the next few mornings, and April’s crescent moon will soon join the parade, according to experts from LiveScience and AccuWeather.”
Yeah, lots of web sites are covering this. At least the one I linked above doesn’t have automated videos, flashing ad gifs, and other random pop-ups that drain your smartphone battery.
Click here for more info about the next great alignment (not as impressive as the so-called “Great Conjunction” a couple years ago, but we’ll see more planets in June and July): https://www.usatoday.com/story/news/nation/2022/04/17/planets-align-april-venus-mars-jupiter-saturn/7351117001/

The iconic “retina scan” scene in Star Trek II: Wrath of Khan was not Shatner’s own eye.
It was an “eye double” software engineer.
(As the man himself says, your iPhone can take a more detailed picture these days, but it was high tech for 1982…)

“We give off waste heat (from industry and homes and so on) and artificial light at night, but perhaps most significantly, we produce chemicals that fill our atmosphere with compounds that wouldn’t otherwise be present. These artificial atmospheric constituents just might be the thing that gives us away to a distant alien species scanning the galaxy with their own powerful telescope.”

Or, as Futurism puts it: “SCIENTISTS ALREADY PLOTTING HOW James Webb COULD DETECT ALIEN CIVILIZATIONS WHOA.”
Just. Settle down, wouldja. Sheesh.
Scientists have proposed aiming the James Webb space telescope the Trappist system, specifically Trappist-1e.
Really hope this isn’t what they find…
