Science information this week: Highly effective photo voltaic storms, exploding comets and pigs from hell

The stars of the present on this week’s science information have been really the celebs themselves. It was a very sensible week for updates and discoveries associated to those celestial furnaces.

Starting near dwelling, the solar spit out three consecutive photo voltaic outbursts towards Earth, inflicting this month’s second launch try of Blue Origin’s New Glenn rocket to be scrubbed and bringing auroras as far south as Florida. Luckily, our planet’s protecting magnetosphere sheltered us from any dangerous results, however extreme geomagnetic storms could possibly be extra damaging sooner or later, owing to a newly found weak spot in Earth’s invisible protect.

The solar additionally performed havoc on the “other comet ATLAS,” when the sun’s extreme gravity caused the comet to explode into pieces following a close flyby. Thankfully, its famous namesake — the interstellar comet 3I/ATLAS — didn’t explode. But it did give off a radio signal — and no, that doesn’t mean it’s aliens.

Earth has it pretty good compared with other planets, however, as astronomers revealed a first-of-its-kind detection of a distant star firing a monster blast powerful enough to rip off the atmospheres of any planets in its habitable zone (a minor blow to the search for extraterrestrial life). Meanwhile, the James Webb Space Telescope may have discovered the earliest and most monstrous stars ever to have formed from hydrogen, helium and dark matter in the young universe.

If all that solar activity leaves you feeling that those pesky stars think everything revolves around them, take some solace: We may have already passed peak star formation, according to the Euclid telescope, and the universe will only get “colder and deader” from here on out.

Scientists spot brains zoning out in real time

Ever get that feeling — say, at the end of the week — when you really want to pay attention to something important, but you just zone out and see people’s lips moving?

Well, scientists finally have a physiological explanation for why this happens when you’re sleep-deprived: Your brain is literally flushing out cerebrospinal fluid, making it nigh-impossible for you to concentrate. The exact functional reason for this is still unclear, but scientists think it could have something to do with sleep-deprived brains switching into sleep-like states, possibly as a form of waking brain waste disposal you missed out on the night before.

Can you have thoughts without a brain? Probably not in the sense that we tend to define them, but it doesn’t mean that brainless creatures — such as jellyfish, sea urchins or sea stars — don’t show some signs of cognition.

Like a pig out of hell

Ever heard of a “hell pig?” Me neither, until this week, but these ancient North American beasts in the genus Archaeotherium could weigh up to 2,000 pounds (1,000 kilograms).

Now, a new tooth analysis has revealed that the hell pigs had different feeding strategies depending on their sizes: The smaller species typically sheared flesh, while the larger species crushed bones with their horrifying teeth (there’s the “hell” part).

Archaeotherium was technically more closely related to hippos and whales than to pigs, but it’s a great name for an animal we’re mostly glad isn’t around anymore — especially as the preserved bites of the larger ones are indistinguishable from those of lions.

Science Spotlight

Compared with classical computers, where do quantum computers excel? One answer sticks out: hacking.

Quantum systems can solve problems related to encryption significantly faster than the classical computers used by nearly all organizations, and cryptographers are facing a major challenge in designing algorithms that will be safe from quantum hacking. But how do you quantum-hack-proof a laptop? Live Science investigated in this Science Spotlight.

Science in pictures

This week’s science image is one thing really particular and, regardless of its preposterous look, totally actual. The gorgeous shot was taken by an astrophotographer who captured a skydiver falling from a airplane 8,000 toes (2,440 meters) away. The picture is called “The Fall of Icarus” and greater than lives as much as its mythic title.

Something for the skywatchers

Save all your wishes for Monday (Nov. 17), when the Leonid meteor shower peaks.

The annual flurry of shooting stars is set to appear in the early hours that day and is produced by tiny particles from the Comet 55P/Tempel-Tuttle that burn up in the atmosphere to make meteors. This year could offer one of the best viewing windows for the fast-moving shower, owing to a nearly moonless night.
