The Aurora from Washington, from a star party in Duval.
It started a bit slow, but then we had this moment where it became incredibly bright & lit up the entire sky. At that moment everyone started cheering together, it was an amazing shared experience.

Interstellar cloud conditions yield ‘impossible molecule’
Discovery of rule-breaking compound hypothesised to exist for decades ‘pushes the boundaries of our understandings of chemistry’Fernando Gomollón-Bel (Chemistry World)
Just before moonset - an infrared view of the one-day old crescent moon next to the Pleiades in the evening sky.
The moon's elevation was only about 1/2 degree above a sea level horizon. (The distant mountain range is 45 miles away, and a few thousand feet lower than the observing location. This means the mountains are at a negative elevation.)
The moon does not appear to be a circle, Instead, it's squashed flat because of atmospheric refraction.
Haze and dust layers are prominent.
Planetarium software says that I was shooting through about 30 airmasses for this image.
Taken from the mountains of southern New Mexico at an elevation of 9,000 feet.
I slightly boosted the visibility of the Pleiades stars in post processing.

There’s a tiny but measurable threat posed by stellar cataclysms such as supernovae and related phenomena such as gamma-ray bursts.
If close enough, these events can disturb telescopes and even damage the ozone layer.

Exploding stars are rare but emit torrents of radiation − if one happened close enough to Earth, it could threaten life on the planet
Some ancient texts record what were likely dying stars, faintly visible from Earth. If close enough, these events can disturb telescopes and even damage the ozone layer.The Conversation
#OTD in 1715.
A total solar eclipse is visible across northern Europe and northern Asia, as predicted by Edmond Halley to within four minutes accuracy. He also drew a predictive map showing the path of totality across Great Britain. The original map was about 20 miles off the observed eclipse path, mainly due to his use of inaccurate lunar ephemeris. After the eclipse, he corrected the eclipse path, and added the path and description of the 1724 total solar eclipse.
Look how tiny JWST's view of the sky is, especially compared to Euclid's wide field of view.
#JWST took an image of the very top of the Horsehead Nebula, focusing in on a region that transitions from a dense, warm area of gas and dust (blue) to an area of hot, ionized gas (red).

Wooooaaahhhh!
The new JWST image of a small bit of the Horsehead Nebula is INCREDIBLE.
To give you a sense of scale here, here’s an image of the nebula from my backyard. That small white box … that’s the JWST field of view! 🤯🤯🤯
Look at ALL those galaxies, all in that tiny white box.

[updated]Dodgy image with white boxes is my own.

Our galaxy seems to be full of "rogue" planets wandering alone between the stars.
A new observation from NASA's TESS space telescope hints that these dark worlds might hugely outnumber the normal (?) planets, like Earth, that bask in the warmth and light of a sun.

The formation of transiting circumplanetary debris discs from the disruption of satellite systems during planet-planet scattering
Several stars show deep transits consistent with discs of roughly 1 Solar radius seen at moderate inclinations, likely surrounding planets on eccentric orbits.arXiv.org
#OTD in 1910.
Halley's comet reappears after 76 years, and Mark Twain dies at his home, Stormfield, the day after the comet's perihelion. In his autobiography, Twain wrote, "I came in with Halley's comet in 1835. It's coming again next year (1910), and I expect to go out with it. The Almighty has said no doubt, 'Now here are these two unaccountable freaks; they came in together, they must go out together.'"
Heads Up!
Extremely Rare #citizenScience opportunity for #astronomy #astrophysics #astrodon #universeodon enthusiasts!
This year, there will be a nova, before or by September, as bright as the North Star.
After peak brightness it will remain bright enough, for several days, to observe with binoculars.
You can help research scientists with observational details.

1/ Most massive stellar #BlackHole in our galaxy found! With 33 times the mass of the Sun, this is the most massive black hole formed after the collapse of a star that we've found so far in the #MilkyWay.
ESA's Gaia mission found it via the wobble it induces on a star orbiting it, and data from ground-based telescopes helped confirm its mass and elucidate how it formed.
