This photo from Argentina is spectacular, and it is also a curious photo because in addition to guessing what these little lines that are seen on the left side of the image are, the Comet I suppose that you can already identify perfectly is the Comet C/2024 G3 Atlas is the protagonist these days, because it is also very visible, especially in the southern hemisphere, but it will be less and less because it is moving away from us.


On January 13 it had its closest approach to the sun at 13 and a half million kilometers from the Sun and that is very close to the sun, that is to receive a lot of energy and a lot of heat from the sun, let us remember that comets are basically objects composed of various ices. in plural, not only water ice, dust and some rocks and now there is news for this poor Comet because it is disintegrating.

The image shows the sequence, and you can see the decomposition of its nucleus, this sequence was taken by the Hungarian astronomer Lionel Majzik but they were taken from the southern hemisphere also from a telescope in Chile and shows a bright serpentine in the nucleus, The point is that the serpentine appeared in the coma, the coma is what the envelope of gas and dust that surrounds the Comet is called, because we cannot actually see the comet nucleus, we see the brightness of that cloud of gas and dust bright, but nevertheless what has been noticed if you see the point on the left is brighter on 18 and 19 a little less.


And the point would be the nucleus, we do not see it, but we see the brightness of its nucleus and what surrounds it, 18 is brighter, 19 is a little dimmer and 20 has practically disappeared, why is it that the head The physical nucleus of this comet has broken into fragments, it has disintegrated due to that heat. Now those fragments will move away from us and who knows if they will return in 160,000 years.


At the moment they are going in the same direction, so there is no problem that one may deviate and come towards us, the comas can be huge, it all depends on the size of the Comet, but also on the composition of its ice because if it is a new comet that It comes from afar and has never come towards the Sun. Its ice is very fresh, to put it in a simpler way, it is very cool and then a much more intense and powerful sublimation of those ice occurs, which creates enormous comas.
