Astronomers have taken the sharpest-ever picture of the interstellar comet 3I/ATLAS, using the Hubble Space Telescope.
Hubble’s observations 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 kilometers, though it could be as small as 320 metres across, researchers report.
While Hubble has given more precise measurements than previous ground-based observations, it still can’t directly see the comet’s solid center. Future observations with other telescopes, including the James Webb Space Telescope, will reveal more about the comet, such as what it’s made of.
