Visitors from young children to adults, even some with a considerable background in astronomy, could classify very distant and faint galaxies with the astrophysicist Karina Rojas. She works with data from ESAs space Telescope Euclid.

I think optical/NIR astronomy could also be interested in such coatings. We paid a lot of money for many-layer coatings of the #Euclid near-infrared filters, and still there was measurable inhomogeneity. I think the company we used already pushed commercial gear to its limits.

Paper Day! Today on ArXiv is #Euclid AGN day. We use Euclid spectroscopy from the Q1 data release to analyse more than 5000 QSOs and derive physical properties. We provide line emission fluxes, FWHM, as well as Black Hole masses and QSO continuum slopes.

Nata per la cosmologia, acquisendo immagini profonde e a grande campo la missione #Euclid si sta rivelando sempre più anche un’eccezionale macchina da "time domain astronomy" – l’astronomia che si occupa di fenomeni transienti, come le supernove. Ne parliamo con Luca Izzo dell’Inaf di Napoli.

Telescope images show fake signals from detectors, cosmic rays, or spacecraft, not real galaxies/stars. NASA's Artifact InSPECtor lets public flag them, improving data for ESA Euclid and NASA Roman Space Telescope.

Space Warps Classify complete!!
Thank you for all the hard work on inspecting #Euclid images! Please join the sprint to finish Space Warps Refine -- we're almost there!

🇪🇸 La #EnergíaOscura no es un campo escalar dinámico. Es el vacío gauge de E8 con invariancia #Lorentz exacta. Predicción: w0 = -1.000, wa = 0.000 exacto. Si #DESIDR3 o #Euclid confirman wa ≠ 0 a 3σ, la teoría queda refutada. Cero parámetros libres para salvarla. #EnergíaOscura #Cosmología

#CitizenScience afficionados, #Euclid scientists would like to again solicit your input for classifying #GravitationalLensing systems. We need a sprint finish before the science analysis can be completed. 18000 galaxies that are maybe acting as lenses are waiting for your eyes and brains.
