Holy cow! Feast your eyes a while, on this gorgeous solar spectrum by the Sol'Ex instrument (assembled by Váradi Nagy Pál). It extends to UV and IR as well as the visible band. Marvel at the F lines, the fine structure, the IR doublets and repeating lines, and the molecular bands. Wonderful! ☀️🧪⚛️🔭

'Double boom': New England residents terrified by massive explosion from outer space

Green meteors—specifically bright green fireballs—are relatively rare and highly striking occurrences. Catching a bright green streak across the sky is a true “right place, right time” moment—especially if it happens to frame perfectly behind an erupting volcano! Watch: youtu.be/kRntP5h3AqI

MIT Haystack Observatory’s SIMONe meteor radar network caught something at the same time that a loud boom was heard over eastern Massachusetts. Scientists are already analyzing the data!

There’s been a noticeable uptick in meteor events recently... interesting.

🌠 BOOM! Bright meteor over Boston today — flash caught by NOAA GOES lightning sensor, boom recorded by Raspberry Shake! GOES shows stunning white-blue flash w/ purple halo over New England. Waveform from AM.R199D spikes at ~18:11 UTC. #Meteor #Boston

There is no chaos from this vantage point... So serene, yet so beautifully fragile.

NASA's James Webb Space Telescope on Flickr (Oct 4, 2022) Combining X-ray data from Chandra with infrared images from Webb, the galaxy cluster SMACS J0723 reveals its vast reservoirs of superheated gas and hundreds of galaxies. flic.kr/p/2nQRZWz

Does this actually end at some point? This looks fun, and I’ve got a spare hour or two, so I might as well dive in.

What's the most obscure pull you can get? Spiral Getty starts with an image from a Wikipedia page of your choice, then spirals outward through images from linked articles. The further you go, the more unexpected the connections get. Take it for a spin yourself ➡️ spiralgetty.wiki

When it comes to synthetic biology and de-extinction, genetic integrity is everything. Replicating life from a degraded multi-generation copy is highly unstable, and even a first-generation clone faces massive hurdles. To truly succeed, you need the pristine, original source material.

Particles of light cannot be divided into smaller particles, but if you try to snip off the end of one, instead of shortening it multiplies

If the Universe is just a simulation running on an alien compiler, did a glitch inadvertently link biological immortality to high-sodium microwave meals?

You’ve probably heard the phrase “once in a blue moon.” But this weekend will bear witness to a true blue moon: the second full moon to appear in the sky in a single month. Here's what to know: https://cnn.it/4uEQ8xI

It's the weekend, baby

Reanalysis shows that the Hubble Space Telescope’s detection of water vapor escaping from Jupiter’s moon Europa might have been a glitch. skyandtelescope.org/astronomy-ne...

It’s a cool monster, by the way. 😀

A decade ago, we discovered an exceptionally exciting exoplanet that could be the best candidate for hosting alien life. Now we’re about to find out if it really is

Our Milky Way is a big dang galaxy. But much, *much* bigger ones are out there that make ours look positively teeny. www.scientificamerican.com/article/how-... 🔭 🧪

I am screaming. Thanks for the breakdown, @theonion.com.

#PPOD: This NASA Hubble Space Telescope image reveals an enigmatic galaxy with a bright center and a face that hints at spiral structure, yet it holds no obvious spiral arms. Reddish-brown clumps and filaments of dust partially obscure the galaxy’s full face... 🧪 🔭

Jeez, just buy the physical copies. At least when a physical book gets blurry, I know it’s just my aging [Earth human] eyes failing me, not the publisher dropping support for my retinas.

This week, a new #HeavyIon run began at the Large Hadron Collider, recreating the extreme conditions of the early #Universe. Here we see event-displays from the LHC experiments: @atlasexperiment.bsky.social, @cmsexperiment.bsky.social, ALICE Experiment, @lhcb.bsky.social.

Deep surveys of the sky have turned up galaxies vastly larger than our own. Are there even bigger ones yet to be seen?

Europa's ocean makes it one of the best places to look for life in the solar system. Water plumes would have made that search easier, if they existed. https://www.sciencenews.org/article/europa-moon-no-water-plumes-space
