Last Notes npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo Uranus and Neptune are different colors, right? Not really. The Voyager 2 images of Neptune were both contrast enhanced and colored a little too blue, differing from true color to bring out the details of the planet. Sorry to ruin your childhood. Here is a re-colored version of the Voyager 2 images, using additional color data from #Hubble and #ESO's Very Large Telescope to get closer to the "true color".

This was basically my PhD supervisor: https://youtu.be/urcL86UpqZc npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo @npub1uw8…88kr I occasionally adjunct and teach an online course. Most of my students are working adults, some are active-duty military. So yes, I get this a lot. One time I had someone miss most of the semester because they were deployed as a military medical evac helicopter pilot and didn't have much internet access. They managed to do all of the coursework in the two days before my grades were due (and actually did a good job!). npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo Ever wonder how much of the celestial sphere #JWST can see at one time? Since we don't want to fry our 10-billion-dollar telescope, JWST always has to face away from the Sun, keeping the Sun behind its sunshield. However, as the telescope orbits the Sun, its view changes. JWST can observe about 39% of the full sky on any given day and can access 100% of the sky over 6 months. https://webbtelescope.org/contents/media/videos/1157-Video https://cdn.masto.host/astrodonsocial/media_attachments/files/111/211/466/643/017/552/original/cd20f60d9d2dddb1.mp4 npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo @npub1tpj…fmcs You can also use from:me to search your own toots, even if you have not opted in to full text search. Way better than scrolling through a year of posts to find an old thread! npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo @npub1tpj…fmcs That fox looks like it will give you a really awesome quest at the observatory. npub1rrgqct54jdq854g5xhmfrwp8glghwxf0ctnsrwczdqs62gwuhw7sh66vty Kelly Lepo @npub1tpj…fmcs Here are the Arp 271 galaxies as seen in Halton Arp's Atlas of Peculiar Galaxies from 1966. The image has been inverted and rotated to match the orientation of the VIMOS image.
