One of the most exciting sunsets I've captured. A thunderstorm came rolling in just as the clouds started to change color. Smith Rock State Park in Oregon.

That little whitish puff just above and to the right of the Boogeyman’s head?

That’s the reflection nebula vdB 62.

Inside it hides HBC 515, a baby orange star only a few hundred thousand years old that’s still having violent tantrums (it’s an FU Orionis-type variable).

The Boogeyman Nebula 🌌

Here's a fun astrophotography target to try with your telescope this season - but be warned, this one takes TIME!

LDN 1622 is a dark nebula in the constellation Orion that resembles 'a dark figure with a head and arms' (I kinda see it!)

This is 10 hours!

It stares back at us from the outer reaches of the Kuiper Belt in a view we’ll never forget.

The image features the view of a vast nebula complex recalling a shark, and so commonly referred to as the Shark Nebula. The bluish-gray silhouette dominates the frame. A darker patch of interstellar dust sits (top-left) over the upper snout. Two reflection nebulae appear like soft blue patches.

I discovered this photo while scrolling through #APOD, and it stopped me cold.

Rodrigo Guerra’s extraordinary image captures 3 rare phenomena together:

- Venus at its maximum splendor
- intense zodiacal light
- a perfectly centered galactic bulge.

Admire this picture of a pitch-black sky over a far hill. Bottom edge: soft orange town glow, black tree outlines. Low left, one razor-sharp white spark (Venus) floats an inch above the line. From it, a faint pale smear stretches up like a quiet fan, fading as it climbs the middle—that’s zodiacal light. Up near the center, a fat glowing blob crammed with pinprick stars: Milky Way’s heart. The galaxy’s streak bends down right, ending in a snug golden dot (Alpha Centauri). Far right, lower, a big milky-white blob (Jupiter) hangs close to the ground. All crisp, quiet, endless.

Look up at Orion with a telescope and spot this weird, faint glow about 800 light-years away: it's IC 2118, the Witch Head Nebula. It's a little disturbing how the dust shapes a dark, stretched-out figure, lit in pale blue by Rigel (that bright star's just outside the top-left corner). Two pointy stars sit right where eyes would be, staring back, and a thin cloudy arm trails off like it's grabbing at something. Everything else is inky black with scattered star specks. Gives me chills every time: pure Halloween in space!

Astronomers sure do conjure up a lot of spooky images when they look out into deep space. A short Halloween thread:

Let's start with the Cosmic Bat Nebula (LDN 43). 🧪🔭

apod.nasa.gov/apod/ap24102...
What is the most spook-tacular nebula in the galaxy? One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night. Located about 1400 light years away in the constellation Ophiuchus, this molecular cloud is dense enough to block light not only from background stars, but from wisps of gas lit up by the nearby reflection nebula LBN 7. Far from being a harbinger of death, this 12-light year-long filament of gas and dust is actually a stellar nursery. Glowing with eerie light, the bat is lit up from inside by dense gaseous knots that have just formed young stars.

Could evolving dark energy lead to a Big Crunch?

#AskEthan

It looks like dark energy *may* be evolving in our Universe, as recent DESI data suggests.

But implying that we're headed for a Big Crunch completely oversells what we know.

Ask Ethan: Could evolving dark energy lead to a Big Crunch?
There's some, but not overwhelming, evidence that dark energy is evolving. What would it take for a "Big Crunch" to be our cosmic fate?

On 17 May 1902, Greek archaeologist Valerios Stais sifted through some artifacts from a shipwreck at Antikythera.

A 2,000-year-old corroded chunk of metal turned out to be part of the Antikythera Mechanism, an ancient analog astronomical computer.

Picture running your hands through cool, thick fog made of cosmic gas and dust. The Pillars of Creation are three giant columns rising gently from bottom to top. The largest sits left, broad and sturdy; the other two taper upward, their tips rounded like reaching fingers. Everything is draped in semi-see-through layers of blue-grey. Only a few red dots glow – baby stars still warm in their dusty cocoons. Farther out, older white-blue stars shine faintly. It’s a quiet, immense place; our entire Solar System could fit inside just one pillar.

What an insane photo! There’s this modern stone monument, the Arctic Henge, standing tall and proud under a mind-blowing aurora in an Icelandic night that looks hand-painted.Greens, pinks, yellows, and reds swirling like living curtains, twisting, weaving, totally hypnotizing. Up top, Polaris shines straight like a beacon. Left side, Ursa Major hanging out; bottom right, Orion peeking in.Seven hours waiting in the freezing cold, nose running, feet numb… and then, bam! This magical explosion of colors. It’s kinda like Stonehenge, but Nordic edition: basically a giant sundial built to snag the sun’s rays, drop shadows exactly where they’re supposed to, and trap the light between these perfectly aligned arches.It’s not just rocks. It’s a place that makes you feel tiny… and alive.

Check out this photo: it's a 527-megapixel mosaic blending Hubble and Webb views of two open clusters, NGC 460 and NGC 456, in the Small Magellanic Cloud.Hubble shows glowing blue bubbles, like fluffy clouds carved by stellar winds—ionized gas that looks like colored cotton.Then Webb comes in with the red: warm dust weaving through delicate filaments, like velvet caverns in the dark.All around, an endless web of gas, dust, and twinkling star points shining in the deep black.It's like peering into a universe of cosmic lace. Stunning.
