Yep! Right now the tail is being viewed at a head-on perspective from Earth (& Hubble), so the tail's behind the nucleus and is foreshortened (said in arxiv.org/pdf/2507.05226). Sorta like looking directly down at the tip of a cone. The tail looks like it's pointed toward the Sun, but it's geometry.

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... 🔭
