And the coma, it's clearly visible and several thousand kilometers across. And a little bit on the coma, it actually just forms, it forms a sunlight, warms the comet, and releases gas and dust, it sublimates gas and dust coming off, and it forms this hazy halo around the nucleus of the comet. And CA-SSIS couldn't measure the coma's full extent because of the brightness, and this brightness fades with the difference from the nucleus, and it just eventually disappears. And usually gas and dust from the coma, they scream away and create this long tail that stretches for millions of kilometers of the comet near the sun. And the tail is much fainter than the coma, so it doesn't appear in some of the current images that these images were taking.
