#JWST is often cited for its amazing work with galaxies, BUT LOOK AT IT DISSECTING UP THE CRAB NEBULA AND SHOWING US STAR GUTS FROM A 1000-YEAR OLD STELLAR DETONATION.
Wow! Look at the pulsar!
So epic that we can see this detail, the different structures, elements, velocities, energies, etc. from an event that Chinese and Japanese astronomers witnessed and documented 1000 years back.
We're connected through time with this event to them!
This week, a science team announced the discovery of JADES-GS-z14-0, a galaxy that existed just 290 million years after the big bang. JADES-GS-z14-0 now holds the record for the most distant known galaxy, with redshift z=14.32.
The discovery is based on spectroscopic measurements made using the Webb telescope of light from this distant galaxy that has traveled for over 13.5 billion years.
Did you know that it's actually NASA/ESA/CSA James Webb Space Telescope? Even though it is often referred to as "NASA" only.
European Space Agency #ESA has contributed the NIRSpec instrument, half of the MIRI instrument, and the launch (including the payload adapter & launch site services) and has 15 scientists working at the science and operations center. #CSA, the Canadian Space Agency, has contributed the NIRISS instrument.
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
