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.
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.
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.
Betelgeuse, the closest red giant to Earth, has long been understood to move between brighter and dimmer in 400-day cycles. But from late 2019 to early 2020, it underwent what astrophysicists called “the great dimming”, as a dust cloud obscured our view of the star.
Now, it is glowing at 150% of its normal brightness, and is cycling between brighter and dimmer at 200-day intervals – twice as fast as usual…It is currently the seventh brightest star in the night sky – up three places from its usual tenth brightest.
Betelgeuse is the closet red giant Star to our solar system, one of the shoulders of the Greek constellation of Orion.
The cultural information in the linked article was actually more interesting than the phenomenon observed. For instance, the fact that an Aboriginal people in Australia saw it long before the Greeks did was something I didn’t know.
And that the Greek name comes originally from the Arabic “bat al-jawzāʾ” meaning “giant’s shoulder.”
And all three cultures saw the star as connected with fire held by a giant hunter of some sort.
And so have ancient Babylonians, Egyptians, and probably everyone else, too. We just can’t help personifying even the stars.
The kicker?
When it does eventually explode, it could – over the course of a week – grow so bright that it will be visible during daylight, and cast shadows at night.
Now that’s something I’d like to be around to see. Hmm. If only I could manage to live for another 10- to 100,000 years…
I got two bone spurs, separated by two years, thanks to playing baseball in junior high school. Both were fingers on my left hand.
The first time was my left thumb first joint. The second time was my left hand ring finger second joint.
Both times, our local health clinic doctor put a metal splint on the finger, wrapped it in flexible bandage and sealed it off with a tiny metal clip.
And of course I stupidly went on playing baseball, because at age 15 guys think they are completely indestructible.
My ring finger stuck out when I batted. I’m lucky I didn’t get hit by a pitch in the hand (I did get hit on the knee, but that’s a whole ‘nother story).
Also, it inspired my baseball novel. So there was a silver lining!
Of all the asteroids they modeled, the one with the largest risk of impact was a kilometer-wide asteroid known as 1994 PC1. Over the next thousand years, the probability that 1994 PC1 will cross within the orbit of the Moon is a paltry 0.00151%, hardly worth worrying about.
Thanks to Glen Hill over at Engagin’ Science (formerly Scientia, which apparently was far too Latin- and science-esque for search engines to handle) for bringing this (not-so Earth-shattering) info to my attention.
Sorry, folks. Hollywood was once again wrong (sigh).
The word has just come in that a fellow traveler has set up his own blog about science.
It’s called Science.
(In Latin, Scientia.)
Glen is a good friend of mine, and not only is he a good scientist, he’s also a good writer. His avowed goal is to raise science literacy and share his love of science with the world.
We may even steal posts from each other from time to time. Or photos (like the one above ⬆️🌏).
While not perfect, this is some seriously scary stuff.
FWIW the researchers themselves did recognize this…
Although it’s nowhere near being able to decode spontaneous thoughts in the real world, the advance raises concerns that, with improvement, the technology might mimic some type of mind reading. “Our thought when we actually had this working was, ‘Oh my God, this is kind of terrifying,’” Huth recalls.
Participants have to consent to being “read,” and there are ways to prevent the software from figuring out even the “gist” of what they were thinking.
Still, imagine if some nefarious criminal group (or governmental agency, if there is a difference) decided to force someone to consent to have their thoughts read.
Long distance.
Permanently.
It’s getting harder and harder to distinguish scifi from reality.
“I was quite surprised by how simple the story hiding behind the curtain of complexity in the data,” Sneppen continued. “You have this immensely complex physics, unimaginable dense stars and the birth of a black hole — and then it all reduces to this beautiful sphere.”
The neutron stars that crashed into each other are “dense and compact,” Sneppen said. They only measured around 20 km in diameter — about 12 miles — but they are “heavier than the sun,” he said. “A teaspoon of neutron star matter weighs more than Mount Everest.”
First reported in 2017, a new study in Nature gives more details about a “kilo nova” only detected by using gravitational waves. The collision led to the formation of a black hole.
Fortunately, this sort of cosmic event doesn’t occur too often. But..
…if a kilonova were to occur in the Milky Way — less than 30,000 light- years away — it would be the brightest star in the night sky, making it discoverable to the human eye…
Still, it’d be safer for Earth if it never happened…
At liftoff time, smoke was seen rising from the bottom of the rocket, indicating the ignition of the main engine. However, the rocket did not rise from the launchpad.
