This greatly limits the resolution the telescope can achieve on a target when only one image is taken. Gemini North has had continuous science operations since 19 May 2020. Jupiter ist der größte Planet des Sonnensystems. NASA's Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms in the solar system, taking place more than 500 million miles away on the giant planet Jupiter. Cool overlying clouds appear as dark regions, but clearings in the clouds allow bright infrared emission to escape from warmer layers below. DOI: 10.3847/1538-4365/ab775f. In these lucky images, much smaller, more complex details on Jupiter are revealed. Figure 4. These images of Jupiter were taken in infrared light (4.7 μm) using the international Gemini Observatory, a program of NSF’s NOIRLab, on 8 April 2019. Over the past three years, researchers have used imaging of Jupiter by Gemini and Hubble to understand Jupiter's wind patterns, atmospheric waves, and cyclones.

Cool overlying clouds appear as dark regions, but clearings in the clouds allow bright infrared emission to escape from warmer layers below. Election Day could turn into "Election Week" with rise in mail ballots. NASA Hopes Martian Winds Could Still Revive Opportunity Rover. Wong (UC Berkeley) and team (Ausschnitt), © International Gemini Observatory/NOIRLab/NSF/AURA M.H. “We used a very powerful technique called lucky imaging,” adds Wong. Together, observations from the three observatories suggest that outbreaks of lightning on Jupiter result from interactions between three types of clouds. Die Ergebnisse werden aktuell auf der Website des Gemini-Observatoriums präsentiert. Join us on The Cosmic Companion Network for our podcast, weekly video series, informative newsletter, news briefings on Amazon Alexa and more! By combining these three pieces of information the research team found that the lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. Like lightning on Earth, Jupiter’s lightning bolts act like radio transmitters, sending out radio waves as well as visible light when they flash across the sky, NASA said in a statement. [1] This corresponds to an angular resolution of the Gemini infrared “lucky imaging” observations down to 0.13 arc-seconds. Unter dutzenden Aufnahmen suchten sie sich dann die schärfsten heraus. With Gemini and Hubble images at multiple wavelengths, researchers now can probe the cloud structure at these locations. Ein Computer wählte davon die schärfsten zehn Prozent aus und überlagerte sie zu einem noch schärfen Komposit. Researchers using a technique known as “lucky imaging” with the Gemini North telescope on Hawaii’s Maunakea have collected some of the highest resolution images of Jupiter ever obtained from the ground. Jeden lichtete das Teleskop 38-mal ab. Phone: +1 510-224-3411 Using multiple instruments, each with its own capabilities, allows astronomers to see targets using multiple instruments at the same time. The Gemini data gave researchers a glimpse down to the deep water clouds, providing them with "another tool for estimating the amount of water in Jupiter's atmosphere," NASA said. Gemini Observatory, Hilo HI Falls Sie schon Kunde bei uns sind, melden Sie sich bitte hier mit Ihrer E-Mail-Adresse und Ihrem Passwort an. NSF’s NOIRLab [1], “These coordinated observations prove once again that ground-breaking astronomy is made possible by combining the capabilities of the Gemini telescopes with complimentary ground- and space-based facilities,” said Martin Still, an astronomy program director at the National Science Foundation, which is Gemini’s US funding agency. Looking at objects over several frequencies of the electromagnetic spectrum can also remove barriers, like clouds of gas and dust, that can obscure some observations.

By combining data from the trio of observatories, it is now possible to answer that question. Credit: NASA, ESA, M.H. Carruthers (STScI). That created a "jack-o-lantern" effect, in which "the warm, deep layers of Jupiter's atmosphere glow through gaps in the planet's thick cloud cover," the press release said. “The Gemini data were critical because they allowed us to probe deeply into Jupiter’s clouds on a regular schedule,” said Michael Wong at the University of California, Berkeley, who led the research team. Did you like this article? Three years of imaging observations using the international Gemini Observatory, a program of NSF’s NOIRLab, have probed deep into Jupiter’s cloud tops. Juno’s instruments could determine the latitude and longitude coordinates of clusters of sferic and whistler signals. Wong (UC Berkeley), and A. James and M.W. In der Aufnahme stehen helle Partien für wärmere Atmosphärenschichten. The images are part of a multi-year joint observing program with the Hubble Space Telescope in support of NASA’s Juno mission. With Gemini and Hubble images at multiple wavelengths, researchers now can probe the cloud structure at these locations. By combining these three pieces of information the research team found that the lightning strikes, and some of the largest storm systems that create them, are formed in and around large convective cells over deep clouds of water ice and liquid. The two telescopes, together with Juno, can observe Jupiter’s atmosphere as a system of winds, gases, heat, and weather phenomena, providing coverage and insight not unlike the network of weather satellites meteorologists use to observe Earth. “At this resolution, the telescope could resolve the two headlights of a car in Miami, seen from New York City,” said Andrew Stephens, the Gemini astronomer who led the observations. As well as the United Kingdom, the others partners in the project are the United States, Canada, Chile, Australia, Brazil and Argentina.
