Its extended coma and developing tail are seen here at a distance of some 290 million kilometers, a mere 16 light-minutes away. Now visible in small telescopes C/2017 K2 will make its closest approach to planet Earth on July 14 and closest approach to the Sun this December. Get an email with NASAs astronomy pic of the day.

Hubble Space Telescope observations indicated the comet had a large nucleus less than 18 kilometers in diameter. Gateway to Astronaut Photography of Earth Monthly Update Astronauts on the International Space Station (ISS) photograph Earth from their unique point of view in low Earth orbit. That put it between the orbital distances of Uranus and Saturn. Then it was the most distant active inbound comet ever found, discovered when it was some 2.4 billion kilometers from the Sun. On its maiden voyage to the inner Solar System from the dim and distant Oort cloud, this comet PanSTARRS was initially spotted over five years ago, in May 2017. Chambo ( Cometografia) Explanation: Imaged on June 20 2022, comet C/2017 K2 (PanSTARRS) shares this wide telescopic field of view with open star cluster IC 4665 and bright star Beta Ophiuchi, near a starry edge of the Milky Way. Reader Susan called my attention to this one, which I liked because it shows all the planets (save Pluto!) in a single photo! Do enlarge it by clicking on it-twice in succession to make it really big. The space agency shared it as their Astronomy Picture of the Day on 18th February. In the following images, youll see tropical cyclones developing, reservoirs filling after torrential rain, wildfires spreading, and urban centers expanding. NASA have posted an image of a stunning dragon-shaped aurora, which was seen lighting up the sky in Iceland this week. We really should start our day by having a looks. Use NASA data, or your own, to create amazing images. This Earth Day we invite you to explore our planet with imagery available through NASAs Worldview satellite imagery exploration tool. This is yesterday’s “Astronomy Picture of the Day” (APOD), and there’s one every day put up by NASA at this site. On Twitter, Facebook, Google News, and Instagram.If you don’t think Pluto is a planet, you won’t be bothered by this, though it wouldn’t be visible anyway. Her work was the first to convincingly demonstrate the dominating presence of dark matter in our universe.įollow HT Tech for the latest tech news and reviews, also keep up with us Part of an investigation to understand how galaxies can grow to such enormous sizes, UGC 2885 was also part of An Interesting Voyage and astronomer Vera Rubin's pioneering study of the rotation of spiral galaxies. That's about 10 times as many stars as the Milky Way. Some 800,000 light-years across compared to the Milky Way's diameter of 100,000 light-years or so, it has around 1 trillion stars. In sharp focus beyond is UGC 2885, a giant spiral galaxy about 232 million light-years distant. In this Hubble Space Telescope image, the bright, spiky stars lie in the foreground toward the heroic northern constellation Perseus and well within our own Milky Way galaxy. It has certainly proved fruitful as most of Hubble's images have been captured by the ACS. The Advanced Camera for Surveys (ACS) was primarily designed to survey large areas of the sky at visible and red wavelengths with 10 times greater efficiency than the earlier premier Hubble camera. Created by the Bruce Murray Laboratory for Planetary Visualization at the California Institute of Technology in Pasadena, the. To capture such objects, Hubble has advanced optical instruments such as the Advanced Camera for Surveys and Wide Field Camera 3. NASA has just released the most detailed 3D map of Mars ever made. February 11 is International Day of Women and Girls in Science, a day set aside to recognize the role women and girls play in science and technology and promote full and equal access to participation in science.
