We followed up #ESAEuclid's near-infrared image of the Dark Cloud LDN 1641 with a comparison to the NIR 2MASS survey, and to a bespoke ground-based image in visible light.

Here's the comparison including a tool to experiment yourself:

Very excited to share the NASA/ESA/STScI press release of our team's work on Apep! It's a terrific writeup, complete with a brand new beautiful visualisation of the nebula geometry.

So when the aurora borealis is faint enough, you can capture its glow with the Milky Way 😍

Berthoud Pass, CO last night
Milky Way to the left and red glow to the right above mountains with just a little snow on them in a very starry sky. I didn't use a star tracker and this was a 30 second exposure so some star trailing is visible.

What if you could capture a two-hour sunset in a single photo?

This composite was built from ~6,000 photos taken on a night in mid-July, each contributing just one column of pixels.

Look closely and you’ll spot stars starting to twinkle in the upper left as the night begins ✨🔭🧪

The Very Large Array, part of The National Radio Astronomy Observatory, was formally dedicated #OTD in 1980.

It was renamed the "Karl G. Jansky Very Large Array" in 2012. Happy 45th birthday, VLA! 🧪 🔭 📡
An image from the movie “Contact” shows Jodie Foster’s character listening to headphones in front of a line of VLA radio dishes that stretch off towards the horizon. One of the dishes is my shaggy golden doodle Linus, wearing a post-surgery cone around his head.

SN Encore: A Second Supernova Seen Several Times

Through a gravitational lens effect caused by a massive foreground cluster of galaxies (MACS J0138), multiple images of a perfectly aligned background galaxy (MRG-M0138) are created, including the supernova Encore it hosts. This image was captured by JWST in 2023.

Like storm clouds rolling over the horizon, a series of new active regions have rotated into view on the Sun this week. So far we’ve seen 10 moderate solar flares in 5 days, with the chance of stronger flares possible. #spaceweather

JWST MIRI NGC1365 - From Judy Schmidt (geckzilla.bsky.social) - https://flic.kr/p/2nECEP6
Dusty, barred spiral galaxy NGC 1365. Interestingly, the dust bar isn't nearly as prominent as it is in visible light. In the center is a modest active galactic nucleus (AGN). The circumnuclear dust is also quite striking. This time, I was happy to receive the PHANGS team's reduction of the data. Makes it much easier because their mosaic was much better matched and aligned. Red (screen layer mode): MIRI F2100W Orange: MIRI F1130W Cyan: MIRI F770W Extra overall brightness in grayscale: MIRI F1000W North is not up.

Another star trail image made a with time-lapse sequence photographed by Kimiya Yui from ISS. All images in the sequence were restored, remastered then retimed using frame interpolation for a short film. These new frames allowed for a simulated long exposure photograph.

A sharp view of a very dusty spiral galaxy. The center glows with a pale but warm yellowish light with two prominent arms of brown dust encircling it. Multiple pockets of blue stars are visible between the spiraling lanes of dust, and a smooth, soft blue halo of light fades to darkness at the edge of the galaxy as the stars and dust become more sparse. A few orangey background galaxies are visible through the dust. The scene is almost absent of Milky Way stars, making it a very clear view of the galaxy.

One of the awesome bits of supernova science I always love is when someone finds a new ancient record of a supernovae! In this case new Arabic records for SN1181 and SN1006 from poems!

New Arabic records from Cairo on supernovae 1181 and 1006
The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000-5000 yr), the unusual star IRAS 00500+6713 with a surroundin...

Star trails from a few years back at Kissimmee Prairie Preserve State Park. This was looking North towards Orlando and, let me tell you, the Christmas season air traffic was not a joy to deal with when I stacked these exposures.

I am honored to be on this week’s episode of Radiolab! The host @lutimestwo.bsky.social gets excited about galaxies with me! We talk about finding light in the darkest places, both for my research and my life. Lulu was so kind talking about my personal life and so intelligent discussing my research.

Not all galaxies wander space alone...and sometimes they're too close for comfort 😔

Galaxies can interact, collide, and merge. By studying snapshots of these interactions, scientists can gain insight into how galaxies evolve over billions of years⏳

The background is black, sprinkled with countless galaxies and stars of varying colors and sizes. A complex yet compact collection of four interacting galaxies. The three galaxies to the left are virtually indistinguishable, with only their cores somewhat standing out. In the "elbow" of these three galaxies is a larger red star. Finally, the fourth galaxy is connected to the three by a barely visible tendril, while a second long tendril extends to the right. The background is black, sprinkled with countless galaxies and stars of varying colors and sizes.
