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

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 now 13...

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

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 it app...

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

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 Paleo...

EXPLAINER-What to expect during the green comet’s encounter with Earth

A green-hued comet that has been lurking in the night sky for months is expected to be the most visible to stargazers this week as it gradually passes Earth for the first time in about 50,000 years. A green-hued comet that has been lurking in the night sky for months is expected to be the most visible to stargazers this week as it gradually passes Earth for the first time in about 50,000 years.The cosmic visitor will swing by our planet at a distance of about 26.4 million miles (42.5 million km). 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. One known come...

NASA Astronomy Picture of the Day 31 January 2023: Green Comet ZTF over Spain

NASA’s Astronomy Picture of the Day is a snapshot of the rare Green Comet ZTF captured in the skies above Spain. NASA Astronomy Picture of the Day 31 January 2023: A comet 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. If you are a fan of watching comets, there is some exciting news for you. A comet which was last seen by Neanderthals is all set to pass Earth this year. The comet is called Comet C/2022E3 (ZTF). It is a long-period comet that originated in the Oort cloud.NASA's Astronomy Picture of the Day is an image of the Comet ZTF captured in a triple view in Caceres, Spain, by astrophotographers Javier Caldera ...

NASA Astronomy Picture of the Day 27 January 2023: Green Comet ZTF lights up the sky

NASA’s Astronomy Picture of the Day is a stunning snapshot of the Rare Green Comet ZTF crossing the orbital plane. 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. When a comet approaches the Sun, the heat causes the ices in the comet to turn into a gas, which surrounds the nucleus of the comet in a bright coma. The gas and dust in the coma form a bright tail that always points away from the Sun. The Earth will soon get to witness a historic moment. An extremely rare comet named Comet C/2022 E3 (ZTF), which last visited us when humanity still lived in caves, is going to pay us a visit.The comet has a period of around 50,000 years, meaning the last time it flew past...

NASA Astronomy Picture of the Day 21 January 2023: Comet ZTF in all its glory!

NASA’s Astronomy Picture of the Day for 21 January, 2023 is none other than Comet ZTF, which is heading for a rendezvous with Earth in February. The rare green comet, which is heading for a rendezvous with Earth soon, is all over the news! This rare comet C2022 E3 ZTF was at perihelion, its closest to the Sun, on January 12. What makes it an interesting celestial object is that it makes a once-in-50000-year appearance. But don't worry, Perigee, which is the comet's closest approach to our Earth, will be on February 1. It is a golden opportunity to watch it. Today, it has been shared by NASA as its Astronomy Picture of the Day.“Comet C/2022E3 (ZTF) is no longer too dim to require a telescope for viewing. By January 19, it could just be seen with the naked eye in this rural sky with li...
