Stunning New Image Shows Comet 3I/ATLAS After Its Closest Pass To The SunA white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

Not All Ice Escaping From Interstellar Comet 3I/ATLAS Forms The Same ShapeFour images showing the distribution of dust, water, organics, and carbon dioxide around comet atlas. Carbon dioxide is very large and circular. Water is smaller but still circular. organics is smaller still and bit squished. the dust is instead very asymettrical longer on side than the other.
