Another “victim” of my sorting & clearing ahead of our move: five copies of my 1988 University of Edinburgh PhD thesis headed for recycling 😬✌️
But don’t panic: these are all water-damaged & I still have eight clean copies of the one hundred originally printed for me during my first postdoc at NASA Goddard 🚀🛰️
The rest were circulated to colleagues back in the early days of infrared arrays in astronomy 🔭
Last year, data from the James Webb Space Telescope soured hopes that TRAPPIST-1 c had an atmosphere that could support life. But recent results have revived those earlier atmospheric hopes. Read more from Big Think. https://flip.it/ClyATt #Science#Space#JWST
#PPOD: M51 (NGC 5194) lies about 27 million light-years away from Earth in the constellation Canes Venatici and is trapped in a tumultuous relationship with its near neighbor, the dwarf galaxy NGC 5195. The interaction between these two galaxies has made these galactic neighbors one of the better-studied galaxy pairs in the night sky. Credit: ESA/Webb, NASA & CSA, A.

"Next steps for the project could include follow-up observations by the James Webb Space Telescope, which would deliver important insights into the planet's surface mineralogy, and the potential for an atmosphere."
I totally love what the #JWST is able to see, such as this new and exciting image of the Horsehead Nebula, where you can see loads of galaxies.
Absolutely amazing!
The image from #ESA even contains a very detailled description, and #astronomical metadata in the AVM format, which my NeoFinder for macOS software of course catalogs, displays, and allows you to search.
Deal and Espinoza present Spelunker: A quick-look Python pipeline for JWST NIRISS FGS Guide Star Data - I love astronomy projects which open up new science from previously unconsidered data streams: it will be very interesting to see what someone discovers with this #JWST data. 🔭🪐 #astrodonhttps://arxiv.org/abs/2405.05453
An article published in the journal "Nature" reports the results of a study of the exoplanet 55 Cancri e, formally called Janssen, which confirms the presence of an atmosphere that is considered secondary, which means that it derives from emissions coming from the planet itself. A team of researchers used observations conducted with the James Webb Space Telescope to detect traces of an atmosphere.
Student paper day! Kleisioti+ on “Direct detectability of tidally heated exomoons by photometric orbital modulation” where she shows that a tidally locked #exomoon with a volcano can be detected with #JWST and two IR bands, even if it’s NOT transiting its parent exoplanet 🔭🪐 #astrodonhttps://arxiv.org/abs/2405.01970

I just love this image - it highlights why we need all the different telescopes: each of them looks at the same object in different ways. And only when working together a complete image emerges.
Here, #Euclid's wide field is combined with #Hubble's zoom-in and #JWST sharpest IR image we ever obtained, allowing us to study how radiation interacts with interstellar matter.
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).
A comparison of the #JWST NIRCam near-infrared and the MIRI mid-infrared views of the top of the Horsehead Nebula
In the NIRCam image, the blue clouds show the warm glow of the nebula, filled with molecules like hydrogen, methane, and water ice. The red whisps are mostly atomic and molecular hydrogen.
In the MIRI image, we see the glowing dust made of silicate particles and soot-like polycyclic aromatic hydrocarbon molecules.
