U.S/CA Keep an eye on the NOAA geomagnetic activity tracker Tonight-Sunday.
Folks as far south as Alabama, U.S may be treated to an #aurora.
In fact, with 5 CMEs headed our way, everyone across the globe should keep an eye on the night time sky.
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
Image de la nuit dernière : l'amas d'Hercule en couleur. Même dans cette image compressée, les spécialistes y verront plein de défauts. C'est normal. Le miroir de mon télescope est dans un état déplorable (bientôt remplacé par un miroir taillé à l'asso Sterenn), la collimation perfectible, le ciel un peu laiteux... Et puis j'ai horreur de passer des heures à traiter une image, à l'ultra-transformer... autant dessiner, ce sera plus naturel. Mais pas mécontent du résultat. #Astrodon#astronomie
Nice artistic rendering of the full variety of diffuse radio emissions we can presently observed and simulated in clusters of galaxies, also when they appear in pairs.
Slide by G.Piagnataro (UNIBO) at the SPARCS meeting.
Correcting a student's thesis or article still is a good way to learn english, and especially to discover things you are used to say since decades are likely wrong.
Latest discoveries for me:
Paranal Observatory was my home away from home for many years. In this blog post Vanessa Peidro Cid, the Head of Paranal Logistics and Facilities, takes us on a behind-the-scenes tour of what it takes to run this small "town" in the Atacama Desert. A lovely piece by Elena Reiriz Martínez, one of our communication interns at ESO.
The Elephant's Trunk Nebula IC 1396 was the target of yesterdays clear night and here I would like to share the result:
My first try on a DSO two panel mosaic.
Guiding and banding noise have been quite a problem for this project, well there is always room for improvements...

Je n'avais pas fait d'astrophoto depuis ... longtemps! Je m'y suis remis la nuit dernière, profitant des conditions météo enfin idéales. J'ai pas mal pataugé avant de pouvoir prendre une série d'images de l'amas globulaire Messier 5 dans la tête du Serpent. Les logiciels d'acquisition et de traitement ont beaucoup progressé en 18 mois... Le weekend n'est pas fini, encore des nuits blanches à venir ! #astrodon#astronomy#astronomie#DeepSky#astrophotography#stars#Ekos#Siril#StarClusters
...Think I am going to move from extragalactic to galactic modelling...the quality of these recent multi-wavelengths composition of exploding stars in the Galactic plane (this one showed by Filomena Bufano at SPARCS) is jaw dropping
(sorry I could not get the full reference to this image - probably still WISE and ASKAP)
M51 #Wirlpool-Galaxie mit #seestar50 im „Äquatorialmode“ mit insgesamt etwa 60 Minuten Belichtungszeit. Ohne Fieldrotation macht das gleich doppelt Spaß.
Mit @Siril_Official gestacked, gestreched und Farbsätting hochgedreht. Keine weitere Nachbearbeitung.
Das LiveStacking Bild vom Seestar sieht in diesem Fall deutlich schlechter aus. Vor allem dank 4 Satelliten und 2 Flugzeugen.
This superposition of Wise (infrared) and Askap (radio) images of a crowded fields with several pulsar wind nebulae in our Galaxies, just presented at SPARCS by Sanja Lazarevic, is just 😱
Have you seen the Crab Nebula observed by LOFAR (including international stations, so higher resolution)?
I just did, at my SPARCS meeting:
gorgeous image by Maria Arias and collaborators:
All our talks given. Interstellar objects brought to a mainly small-bodies audience, and it also enthused the mission engineers! Very proud of our group, a lot of work from five of us leading up to this #astrodon
Wonderful news. The Gruber Foundation presents the 2024 Cosmology Prize to Marcia Rieke for pioneering work on astronomical instrumentation to reveal the breadth and details of the infrared universe. https://gruber.yale.edu
(She was actually my teacher at the Vatican Summer School in 1993 and later I sat next to her at the MMT in Arizona conducting near-infrared observations. What a great person and scientist!)
Couple of slides from the talk I just gave to the SPARCS XII conference in Bologna, on th theme of:
"Numerical simulations keeping up with the complexity of radio discoveries"
Globular clusters not only exist in galaxy’s halos. M71 is practically embedded in Milky Way’s disc, just halfway (apparently) in between Albireo and Altair. This globular cluster has another peculiarity: it is rich in metals which is unusual for an old object like this.
