Having one comet on an image is something cool, but having 2 close to each other is even cooler!
The bigger one -
C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022. The cool thing about it is that it last passed through the inner solar system around 50,000 years ago. That means our planet was in the midst of the last glacial period or "ice age" and Neanderthals still shared the planet with our early ancestors, the first homo sapiens. Comets are also fast moving objects. ZTF, while the closest Earth approach, was moving at a speed of 57.4 km/s relative to the Earth and 39.1 km/s relative to our Sun!
The small one -
C/2022 U2 (ATLAS) was discovered by Asteroid Terrestrial-Impact Last Alert System (ATLAS) search program on October 25, 2022. You can see it as a faint green blob.
