Hubble sizes up rare interstellar comet

A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS, using the crisp vision of the NASA/ESA Hubble Space Telescope.
ESA's Planetary Defence Office responded promptly to the discovery of the comet, and has been tracking it since the beginning of July.
Now, Hubble's observations from space are allowing astronomers to more accurately estimate the size of the comet’s solid icy nucleus. The upper limit on the diameter of the nucleus is 5.6 km, but it could be as small as 320 m across, researchers report.
Though the Hubble images put tighter constraints on the nucleus size

ESA astronaut Raphaël Liégeois from Belgium, a member of the ESA Astronaut Class of 2022, was selected in November 2022 from over 22,500 candidates who applied to ESA’s 2021 call for new astronauts.
He began his year-long basic astronaut training at ESA’s European Astronaut Centre (EAC) in Cologne, Germany, in April 2023. This training covered spacecraft systems, spacewalking, flight engineering, robotics, life support systems, survival, and medical training. Raphaël received his astronaut certification alongside fellow astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, and Marco Sieber at EAC on 22 April 2024, officially marking his transition into
