And another post to which I forgot to add a title…
In a few billion years, our aging Sun will run out of hydrogen fuel in its core and begin to swell, eventually engulfing Mercury, Venus, and probably Earth itself. Known as the red giant phase, this is a normal step in a mid-sized star’s life cycle, when it swells to hundreds of times its usual size. There are plenty of red giants in the night sky, but astronomers have never caught one in the act of swallowing its planets — until now.

Pack your stuff, folks…
The photo is an artist’s depiction btw. The article describes how the astronomer discovered that star was eating its own planet.

And by the way, thanks for reading!
I’m sorry that I haven’t been posting much lately. Work has just become completely overwhelming, and the rainy season (here in Japan) hasn’t helped.
But I do read your comments and I appreciate them, and all your “likes,” too!
Just realized it’s been MONTHS since I posted the next installment of Bringer of Light.
Yikes.
Time to wrap up the first book and get to the climax already!

Chemical traces reveal first-generation stars
The link below includes a night sky in Montana, which makes little sense when the researchers were in Beijing and Honolulu…
“The first-generation star we observed has the potential to become the oldest star we have ever seen,” said Alexander Heger, a professor in the school of physics and astronomy at Monash University in Australia who was part of the research team. “It probably had only lived for 2 1/2 million years and then exploded.”

Oh, and it also was discovered to be 260 times the size of our own Sun…just as theorized.
More importantly, this involved scientists from three different countries (China, Japan, and Australia), sharing information and working together for science.
Imagine if that spirit of cooperation could be extended into other domains…
Subaru, how about you?
And today’s vague prompt is…
What notable things happened today?
What do you mean, notable to me, notable to others, notable throughout history or just notable in general?

Something else for future potential Mars settlements to consider….
Plume of water seen on Saturn’s moon
The record-breaking plume reached nearly 6,000 miles into space – covering the distance between Ireland and Japan – and poured water into the void at an estimated rate of 300 litres a second.
https://www.theguardian.com/science/2023/may/30/astronomers-see-6000-mile-water-vapour-plume-blasting-from-saturn-moon
Note that the water jetted out into space nearly 40 times longer than the actual size of the moon (about 500 in diameter, or as the Gurdian puts it “500-mile-wide” for those who forgot the meaning of “diameter).
Enceladus is probably the best bet for life elsewhere in the solar system due to its water — and while whipping around Saturn once per day, which is likely the reason for underwater volcanos and other vents that may provide the proper chemistry for life.
Also the perfect place to trick an inexperienced asteroid hunter crew…

This is such a Gen-X prompt…
Do you remember life before the internet?
May as well ask if the writer can identify all the ancient objects in this photo…
Only an hour to Manhattanhenge!
Manhattanhenge, a portmanteau of “Manhattan” and “Stonehenge,” is a twice-a-year solar event when the sunset lines up directly with the city’s grid, casting golden rays down city streets. Several of the stones in Stonehenge, the prehistoric monument in Wiltshire, England, experience perfect alignment with the sun during the summer and winter solstices, which is why the event takes its name from the rock formation.

If you miss it today, don’t fret: it happens again in July during MLB’s All-Star Break.
And the next day after each “half-sun” event, you can still see the “full-sun” version. Anybody in NYC?
