Went apple picking, had a cider donut (or two), and baked a pie -- feeling the #Fall vibes🍂

And thus, the Jack-o-Lantern nebula!

Infrared image of the Jack-o’-Lantern Nebula captured by NASA’s Spitzer Space Telescope, showing a glowing cloud of green and orange gas and dust with a bright red center shaped like a carved pumpkin, surrounded by a field of blue stars scattered across space.

"Zwanzig Jahre lang gibt ein eigenartiges Licht auf einem Herbig-Haro-Objekt Rätsel auf. Neue Bilder des James-Webb-Teleskops liefern jetzt eine Erklärung. Woher das Licht kam, erklärt Josef M. Gaßner in diesem Video von »Urknall, Weltall und das Leben«."

This is Messier 82 — located in the #constellation Ursa Major!

We covered Ursa Major at the beginning of Season 3!

Composite of images of the active galaxy Messier 82. In the center of the image is a long cigar-shaped green and white light. In the center going up and down the image are clouds of gas/dust in red and blue.

Pretty in pink, ahem, I mean infrared, Pleiades!

An image showing the Pleiades star cluster, also known as the Seven Sisters, captured in infrared light. Many stars, both faint and bright, are scattered across the frame, surrounded by wispy clouds of interstellar dust glowing in shades of red, orange, and pink. The dust forms sweeping patterns, with several particularly bright stars creating radiant flares against the textured backdrop.

Herbig-Haro 49/50 (Spitzer and Webb Images Side-by-Side)

This side-by-side comparison shows a Spitzer Space Telescope Infrared Array Camera image of HH 49/50 (left) versus a Webb image of the same object (right) using the NIRCam (Near-infrared Camera) instrument and MIRI (Mid-infrared Instrument).

The Webb image shows intricate details of the heated gas and dust as the protostellar jet slams into the material. Webb also resolves the “fuzzy” object located at the tip of the outflow into a distant spiral galaxy. The Spitzer image shows 3.6-micron light in blue, the 4.5-micron in green, and the 8.0-micron in red (IRAC1, IRAC2, IRAC4). In the Webb image, blue represents light at 2.0-microns (F200W), cyan represents light at 3.3-microns (F335M), green is 4.4-microns (F444W), orange is 4.7-microns (F470N), and red is 7.7-microns (F770W).

#Welt! Bist du noch da?

#Frühlingsgefühle

#8ung, 8ung!

Im #Frühling gibt es nicht nur gutes #Wetter, sondern auch in der #Tierwelt #Hormonausschüttungen. Damit werden die wilden #Tiere unberechenbar.

Meine persönliche #Wildunfallstatistik der letzten 30.000 km mit dem #Rad:

#Wildschwein - 0
#Reh / #Hirsch - 0
#Hase - 0
#Spitzmaus - 1
#Waschbär - 0
#Ente - 1

Bei der Spitzmaus ( #Spitzer ) bin ich mir nicht sicher ob sie einfach an #Herzklabastern verstorben ist, aber passt auf Enten auf, denn wenn die euch im vollen Flug mit 1000g #Lebendgewicht an der Schulter treffen, dann hält man sich kaum noch auf dem Rad.
Vor 2 Jahren für euch überprüft!

So, jetzt n’ #Kaffee und dann ab durch die #Nacht, oder so!

Schnell noch was aus der #Mottenkiste:

Ja das sollten wir! Aber halt nicht indem wir *nicht* digitalisieren sondern indem wir #FOSS verwenden.
Mit der Evidenz ist das halt auch so eine Sache bei #Spitzer

They observed WASP-12 b 45 times with #CHEOPS and used #TESS and #Spitzer data to study the phase curve including tidal deformation.

Why is tidal deformation important? If you don’t account for the shape, you’ll overestimate the density of your planet.

The phase curves allow to calculate the Love number which should tell us about the core mass fraction. Sadly not very well constrained, so we need #JWST for that instead. They’ll be doing that for WASP-103 b.

#ExSSV

We continue with Jonathan Fortney on GJ436 b - the original archetype #warm #Neptune

It has an intriguingly “large” eccentricity (I disagree that 0.14 is large sorry 🤓).

Thermal emission from the planet showed to be different for the #Spitzer points, at the time explained through atmospheric chemistry: non-equilibrium + mixing.

Reanalysis + follow-up showed a lower point at 3.6 micron, so less bright, but still brighter. Suggestion: tidal heating driving up the interior? #ExSSV

Featured in Nature's selection of the best #science images of the month: a composite image of the Cassiopeia A #supernova remnant that brings together data from several #NASA telescopes: X-rays from #Chandra, infrared from #JWST & #Spitzer, optical data from #Hubble.

Chemical Soups Around Cool Stars

This artist's conception shows a young, hypothetical planet around a cool star. A soupy mix of potentially life-forming chemicals can be seen pooling around the base of the jagged rocks.

Zum 1. Advent gönne ich mir eine Manfred #Spitzer Leseprobe "Künstliche Intelligenz. Dem Menschen überlegen – wie KI uns rettet und bedroht". - Das passt gut zum heutigen Evangelium Mk 13, 33-37: Seid wachsam! - Allen eine besinnliche und wachsame Adventszeit 🕯.
