South Korea's first moon mission is beaming back images of home from its position in low lunar orbit.Danuri, also known as the Korea Pathfinder Lunar Orbiter (KPLO), launched aboard a SpaceX Falcon 9 rocket in early August last year and arrived in lunar orbit four months later, in mid-December. The milestone adds South Korea to the exclusive club of nations with successful moon missions, which also includes Japan, China and India, among others.

 See a possible naked-eye comet at its closest to the sun on Thursday (Jan. 12)By Robert Lea published about 6 hours ago On Thursday (Jan.12) a comet that hasn't visited Earth or the inner solar system since the last ice age will reach its closest point to the sun, also known as its perihelion. The comet, designated C/2022 E3 (ZTF), will come to within around 100 million miles (160 million kilometers) of the sun. Following the perihelion, the comet will then move towards Earth making its closest approach to our planet, its perigee, on Feb.2 when it will whip past us at a distance of 26 million miles (42 million kilometers). |

 In case you haven't heard yet, a rare green comet that hadn't been seen since the time of the Neaderthals made its closest approach to Earth on Wednesday (Feb. 1), thrilling astronomy geeks all over the world. Just type "comet" into the Twitter search box, and you will see scores of stunning images capturing the green-tinged blot shining bright in the middle of the star-studded sky in all sorts of variations. "A comet last visible during the Stone Age has appeared for the first time over Stonehenge," English Heritage, which manages the iconic prehistoric monument in the south of England, said in a tweet accompanying a stunning photograph of the comet above the stone circle. "The last time the green comet, called C/2022 E3 (ZTF), was visible from Earth was around 50,000 years ago, long before the stone circle was built." Related: How to see the green comet C/2022 E3 (ZTF) visible in the night sky now as it approaches Earth The photo was snapped by experienced astrophotographer Josh Dury, who told Space.com that taking the image was "one of the most challenging" astrophotography projects he had ever undertaken. "With thick freezing fog rolling in over Salisbury plain [where the stone circle is located], my camera equipment was freezing up and there were only short interludes of clear skies," Dury wrote in an email to Space.com. "Luckily the comet was visible for a period of time where I was able to capture this image, really a once-in-a-lifetime opportunity." The green comet, discovered in March 2022 by the Zwicky Transient Facility in California, made its closest approach to Earth on Wednesday night (Feb.1) into the early morning hours of Thursday (Feb. 2) in Europe. At its closest, the comet came within 26 million miles (42 million kilometers) of our planet, which is equivalent to about 28% of the distance between Earth and the sun. A Twitter user called Susanoo Harlock shared another stunning snap of the comet shining bright above a Japanese castle. "Comet C/2022 E3 (ZTF) came to Earth in 2023 for the first time in 50,000 years," Harlock said in a tweet. "My life is very fortunate to be able to see such a spectacular celestial show while I am still alive." |
