On February 1, the green comet ZTF made its closest approach to Earth, watched by astronomers and sky watchers around the world. Comets are of great interest to scientists because they are remnants of the early solar system, providing valuable information about its composition and conditions. While comets often pass close to Earth, Comet C/2022 E3 (ZTF) is particularly notable because it has an orbit of 50,000 years, meaning the last time it came close to Earth was about 50,000 years ago during the Upper Paleolithic. was in the era when the Neanderthals were. still exists on earth.
NASA’s Astronomy Image of the Day is a breathtaking image of Comet ZTF over Yosemite Falls in the Sierra Nevada region of California. According to NASAThe comet was discovered by astronomers using the Wide Field Survey Camera at the 2022 Zwicky Transient Facility in March last year. Comet C/2022E3 (ZTF) is a long-period comet that originated in Oort. the cloud. This photo was taken by astrophotographer Tara Mostofi.

They are both falling. Water is falling towards the ground at Yosemite Falls in the US state of California. Comet ZTF is falling toward the Sun. This double cosmic cascade was captured late last month as the faint comet C/2022 E3 (ZTF) just passed close to its home planet, Earth. The orange star just above the waterfall is Kochab. With the exception of a brief encounter with a black bear, the featured image was a planned mix of foreground and long-term background exposures of moonlight—all designed to recreate a darker version of a true singular vision. was
Although Comet ZTF now fades as it turns toward the outer Solar System, its path is determined by gravity and so it can still be thought of as falling toward the Sun — but backwards.
