I've been meaning to check out this early release Euclid data. It's pretty amazing. I've been watching the image releases and feel like they have a few issues with color balance and clipped histograms. After some investigating I still think that's true. Here's a roughly processed image. You can compare them yourself and see if you agree. https://www.esa.int/ESA_Multimedia/Images/2024/05/Euclid_s_new_image_of_star-forming_region_Messier_78

There are a lot of different ways to check your processing for color balance, but I think one of the more fun ones is to take a look at the diffraction spikes. With well separated wideband data, it always comes out colored like a rainbow. If your diffraction spikes aren't prismatic, things might be off (or you might have a really red star.)

The summer 2024 NASA's Astrophoto Challenge is now open! This summer's target: Cassiopeia A.

Make your own images with real NASA data using a simple, online tool. Then, submit your image. Standout entries are featured on the website and get comments from expert judges.

I find all of your technicolor space images delightful. Please go make some weird space pictures:

The word’s largest camera built for astronomy & astrophysics has arrived at Rubin Observatory!

The LSST Camera completed a cross-continental trek from SLAC after two decades of work, marking the arrival of Rubin’s last major component in Chile.

Tomorrow, 23 May, 12:00 CEST, and the @ec_euclid will present 15 papers, including first results:

5x reference papers about the main mission, the instrumentation, and related cosmological simulations

10x Early Release Observation papers, ranging from ... near to far

At the same time ESA will make 5 new ERO images public and the underlying science images. This programme was observed before the start of Euclid's main survey.

Stay tuned!

: This stunning photo was taken by the High Resolution Stereo Camera (HRSC) onboard the ESA's Mars Express spacecraft. Phobos is the larger and closer of Mars's two moons, the other being Deimos. One hypothesis of their origin involves the possible capture of primitive asteroids. Unfortunately, Phobos is being pulled apart and closer by Mars's tidal forces and gravity.

I feel like all that time I’ve been practicing shading is starting to pay off.

Sitting atop a fractal surface of black holes, Tribert tries to make Adenine, one of the molecules in DNA, but he didn’t get it quite right, probably because he got distracted by the cats. Maybe next time, Tribert.

Chemistry is like physics where the particles have personalities - and chemists love talking about the really nasty ones. It makes for fun reading, like Derek Lowe's column "Things I Won't Work With". For example, bromine compounds:

"Most any working chemist will immediately recognize bromine because we don't commonly encounter too many opaque red liquids with a fog of corrosive orange fumes above them in the container. Which is good."

And that's just plain bromine. Then we get compounds like bromine fluorine dioxide.

"You have now prepared the colorless solid bromine fluorine dioxide. What to do with it? Well, what you don't do is let it warm up too far past +10C, because it's almost certainly going to explode. Keep that phrase in mind, it's going to come in handy in this sort of work. Prof. Seppelt, as the first person with a reliable supply of the pure stuff, set forth to react it with a whole list of things and has produced a whole string of weird compounds with brow-furrowing crystal structures. I don't even know what to call these beasts."

One year ago, we converted a small piece of boring grass in front of our institute into a wildflower meadow. Now it's blooming for the second time, attracting many insects, and improving the biodiversity and the micro climate around our institute.

Ouch 😬

Fingers crossed for my friends in the ESA mission operations team & colleagues from industry as they work to restore the solar electric propulsion system to full power 🤞

The SEP system is critical to adjust Bepi’s trajectory between the various Mercury flybys, slowing the spacecraft down ahead of entry into orbit around this enigmatic innermost planet in December 2025.

If you own a Tesla, your car is covered in cameras that take images reviewed by Tesla employees, who share them with each other, joke about them, and make them into memes.

Uh-oh! BepiColombo, the joint ESA/JAXA mission to Mercury, has experienced an issue that is preventing the spacecraft’s thrusters from operating at full power.

uses solar arrays and electric propulsion to generate thrust during its complex journey from Earth to Mercury.

After a problem on Apr 26, electrical power from the Transfer Module was restored to 90%, but it is not sufficient for full thrust.

The 4th gravity assist is planned for Sept.

To my European followers:
It looks like the solar storm might arrive earlier than expected (it already did partially!), which means very good chances tonight for Aurora over Central Europe!
https://www.swpc.noaa.gov/products/alerts-watches-and-warnings

The current model run from NOAA SWPC already predicts Aurora as far south as Cologne! And levels may very well increase during the night!

I wish you all good luck and most importantly clear skies!
