Two hours later (Jul 21, 18:05 UTC), Hubble took some more images of 3I/ATLAS!

BTW, you can download and see the calibrated (DRZ) Hubble images yourself at mast.stsci.edu/search/ui/#/.... You'll need a program that can open FITS-format images (like Aladin, FITSviewer, etc. Go wild with em)

Hubble Space Telescope images of interstellar comet 3I/ATLAS are out! These were taken 5 hours ago. Plenty of cosmic rays peppering the images, but the comet's coma looks very nice and puffy. Best of luck to the researchers trying to write up papers for this... archive.stsci.edu/proposal_sea... 🔭

Olivier Hainaut & others got some really nice images of 3I/ATLAS's fuzzy coma with the Very Large Telescope last night! The images are already public on the ESO science archive. archive.eso.org/downloadport...

Here's our images of interstellar object #A11pl3Z from Deep Random Survey's 0.43-meter scope @ Chile. The telescope was following A11pl3Z's motion, so stars appear smeared. Weather got worse by the end, so still hard to tell if it's a comet.

600-sec exposures, from 2025 Jul 2, 00:42-01:23 UT

UPDATE on our new interstellar friend #A11pl3Z:
Citizen scientist Sam Deen has found earlier observations of from June 25-28, from the ATLAS telescope!

Now with 6 days' worth of data, the eccentricity of A11pl3Z's trajectory is narrowed down to e=10.4 ± 1.1!
... that's undoubtedly interstellar.
