NASA Astronomy Picture of the Day 24 March 2023: Comet ZTF and the stars of Milky Way

[ad_1] Comets are of great interest to scientists as they are remnants of the early Solar System, providing valuable information about its composition and conditions. One of these is the Rare Green Comet ZTF which made its extremely rare approach to Earth just last month. The tech that discovered Comet ZTF was the wide-field survey camera at the Zwicky Transient Facility in 2022 in March last year.While comets often pass close to Earth, Comet C/2022 E3 (ZTF) is particularly noteworthy because it has a 50000-year orbit, meaning the last time it came close to Earth was almost 50000 years ago during the Upper Paleolithic period when Neanderthals were still present on Earth. Today's NASA Astronomy Picture of the Day is a picture of Comet ZTF fading away in the sky. According to NASA, it is ...

Forget Comet ZTF, Comet Tsuchinshan–ATLAS could shine brighter than stars

[ad_1] Although Comets often make trips to Earth, the Comet ZTF which passed Earth last month was an extremely rare sight. It has a period of approximately 50000 years, meaning it was witnessed by Neanderthals the last time it passed by Earth. A comet also orbits the Sun, but unlike an asteroid, it's composed of ice and dust. When a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and has a tail. Now just a month after its passing, it seems like Comet ZTF has become old news as a new Comet is expected to pass by Earth in 2024, and it could be a special one.Comet C/2023 A3 discoveryThe Comet, known as C/2023 A3 (Tsuchinshan–ATLAS), was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) in So...

NASA Astronomy Picture of the Day 21 February 2023: Comet ZTF over Yosemite Falls

[ad_1] On February 1, the Green Comet ZTF made its closest approach to Earth, which was observed by astronomers and sky-watchers worldwide. Comets are of great interest to scientists as 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 noteworthy because it has a 50000-year orbit, meaning the last time it came close to Earth was almost 50000 years ago during the Upper Paleolithic period when Neanderthals were still present on Earth.NASA's Astronomy Picture of the Day is a mesmerizing picture of Comet ZTF streaking across the skies over Yosemite Falls located in the Sierra Nevada region of California.

NASA Astronomy Picture of the Day 13 February 2023: Green Comet ZTF flies past Mars

[ad_1] Although comets often make close flybys, the Comet C/2022 E3 (ZTF) is particularly special as it has a period of around 50,000 years. That means the last time it flew past Earth closely, it was witnessed by Neanderthals during the Upper Paleolithic period on Earth nearly 50000 years ago. Comet ZTF recently made its trip to Earth and came closest to the planet on February 1, after which it went on its journey again. A couple of days ago, the comet came across another nearby comet called Comet C/2022 U2 (ATLAS) near the constellation Auriga. Now, Comet ZTF has been captured passing Mars.NASA's Astronomy Picture of the Day is a picturesque image of Comet ZTF as it swept past Mars on February 10 and 11. Although it wasn't visible visually, its picture was captured by astronomers as ...

NASA Astronomy Picture of the Day 10 February 2023: Awesome! Comet ZTF meets Comet ATLAS

[ad_1] The Green Comet ZTF passed Earth at its closest distance on February 1 and it was seen by astronomers and sky-watchers alike all over the world. Comets are of interest to scientists because they are remnants of the early Solar System, and can tell us about the conditions and composition of the early Solar System. Although comets often make close flybys, the Comet C/2022 E3 (ZTF) is particularly special as it has a period of around 50000 years. That means the last time it flew past Earth closely; it was seen by Neanderthals during the Upper Paleolithic period on Earth nearly 50000 years ago.NASA's Astronomy Picture of the Day is a breathtaking picture of the Comet ZTF racing across the skies as it passed another comet named Comet C/2022 U2 (ATLAS) near the constellation Auriga.

NASA Astronomy Picture of the Day 3 February 2023: Comet ZTF leaves awesome trail

[ad_1] Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. When a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and has a tail.Although comets often make close trips to Earth, one particular comet has intrigued astronomers and skywatchers alike. The comet is called Comet C/2022E3 (ZTF) and it is a long-period comet that originated in the Oort cloud. What's shocking about this comet is the last time it came close to Earth; it was seen by Neanderthals nearly 50000 years ago in the Upper...

Here is an explanation of comets in general and this one in particular. WHAT IS A COMET?Nicknamed "dirty snowballs" by astronomers, comets are balls of ice, dust and rocks that typically hail from the ring of icy material called the Oort cloud at our solar system's outer edge.

Rare green comet will make its closest approach to the Earth TOMORROW; Know how to see it

[ad_1] The rare green comet which entered the inner solar system after 50,000 years will be making its closest approach to the Earth tomorrow, February 1. Find out the best way to see it. The world of astronomy has been dominated by the news of the green comet. Also known as Comet C/2022 E3 (ZTF), this ancient icy comet last came this close to our planet 50,000 years ago. Back then, Neanderthals still roamed the Earth. And that's why you should not let go of this incredibly rare moment and make sure to watch it in the night sky tomorrow, February 1. The best part about this comet is that it will even be visible to the unaided eye. But where should you look in the sky to be able to watch it?

Green comet zooming our way, last visited 50,000 years ago

[ad_1] A comet is streaking back our way after 50,000 years. A comet is streaking back our way after 50,000 years. The dirty snowball last visited during Neanderthal times, according to NASA. It will come within 26 million miles (42 million kilometers) of Earth Wednesday before speeding away again, unlikely to return for millions of years. So do look up, contrary to the title of the killer-comet movie “Don't Look Up.” Discovered less than a year ago, this harmless green comet already is visible in the northern night sky with binoculars and small telescopes, and possibly the naked eye in the darkest corners of the Northern Hemisphere. It's expected to brighten as it draws closer and rises higher over the horizon through the end of January, best seen in the predawn hours. By Feb....
