La NASA publie de nouvelles images de la comète interstellaire 3I/ATLAS  La NASA a diffusé des images rapprochées de la comète interstellaire 3I/Atlas, seulement le troisième objet connu venu d’une autre étoile. Après son passage près de Mars, elle s’approchera à 269 millions de km de la Terre en décembre avant de repartir pour toujours.

00:30The shape of the nucleus is also difficult to pin down because generally we're not resolving

00:45it in our observations.

00:47It's obscured by the dust and especially it's obscured by the reflected sunlight off

00:53of the dust in the inner part of the coma.

00:55But what observers from the ground have been able to do is observe the brightness of the

01:01center of the comet over time to see if there's a modulation of that brightness that would

01:06be an indication of rotation.

01:09And it's very difficult to discern.

01:11So what it's looking like so far is that the shape of the nucleus is not very far from

01:20being round.

01:21It doesn't seem to be a big or at least we're not seeing signatures of a very elongated object

01:25yet.

01:26So what I'm talking about is that the stars are just the same as the coorden of the

01:29object.

01:30So what we're describing here at the end of the comet is the same as the surface of the

01:36immune system and the intensity of the suction system is also reduced to the surface.
