The unusually green-hued comet ZTF, also known as ZTF (C/2022 E3), developed a strange and rare tail yesterday, pointing toward our sun rather than trailing out behind it.

This is known as an "anti-tail," and appears to point in the opposite direction to the usual comet tail—seemingly breaking the laws of physics.
