Yes, the fish doorbell has started its season. It is in the city of Utrecht in the Netherlands. The mating season of many fish takes them right across the city up the rivers. To help them, press the button if you see a fish on camera so the sluice doors can be opened. #vis#fish#wildlife#biodiversity
Ça fait une demie heure que je tape comme un con avec un tournevis à frapper dans cette vis, je l'ai à peine entamée, elle est totalement morte j'ai plus d'idée de comment la virer. Vous avez des trucs vous ? #bricolage#vis#problème#needhelp
Ik lees dat #collageen supplement voor vrouwen in de #overgang over t algemeen betrouwbaar werkzaam is.
Vandaag bij H&B even gaan kijken en ik ben best geschrokken van de prijzen. Voor gewrichten zou viscollageen het beste maar....#vis? Ik ben niet #vegan maar me wel bewust van de visachterstand.
Echter, ik kan geen goede info vinden over vergelijkend onderzoek. Vegan collageen, werkt dat wel?
Het ratelt rond in mijn hoofd dus ervaringsdeskundigen, ik hoor graag jullie mening. #menopause
Coming Monday (31. July) we will declare "First Light" for #ESAEuclid 🛰️ and show the first engineering images that the #VIS and #NISP instruments 📷 have taken of the sky, using a fully focussed telescope! 🔭
Yay! 🥳
That said, #Euclid has now also arrived at its ultimate distance from Earth, circling around the Sun-Earth Lagrange point 2 😎🌏🛰️ - joining #ESAGaia and #JWST:
The #NISP team has completed #commissioning of the second of #ESAEuclid's instruments. ✅ NISP is the "Near-Infrared Spectrometer and Photometer"🌈, working in parallel to #VIS. NISP is working fine! Another big step for the mission! 🎉
All you need is a large-ish telescope 🔭, in this case the 3.6m Canada-France-Hawaii-Telescope on Maunakea, Hawai'i 🌋. 26 images of each 3min integration were combined into this video. Euclid had a distance of 920,000 km from Earth!
Here the very wide-field MegaCam on the CFHT #telescope was used, a camera 📷 that in its design was a precursor to #VIS, the wide-field visible wavelength instrument now onboard #ESAEuclid. How wide field? Well, the full area covered by MegaCam is about 80 times larger than the area shown in the video.
#ESAEuclid has not yet been focussed, meaning that the secondary mirror ("M2") is in its safe position for launch and images would still be blurry 🔍. Focussing will take more than a week starting coming Monday.
Meanwhile the #VIS team has completed instrument #commissioning. ✅
All working well, both in space as well as on ground, some minor things are being investigated. A big step! 🎉
Update on #ESAEuclid#commissioning: while the whole spacecraft 🛰️ continues to cool down, the #VIS instrument checked out its electronics, shutter, and calibration lamp 💡 and they all react as expected. The #NISP instrument has rotated its filter and grism wheels 🎡 successfully.
Next up is full VIS & NISP commissioning, before the telescope 🔭 optics will undergo a week of alignment & focussing.
Really excited to launch The Journal for Visualization and Interaction (JoVI)! A new open journal for #VIS and #HCI
Best part (IMO) is the experimental track, where you can submit papers using @Posit's #quarto and have them reviewed via Github. Also means interactive papers (e.g. using JavaScript @observablehq) are supported!
