These images show Jupiter moon Io obtained at different infrared wavelengths with the W. M. Keck Observatory 10-meter Keck II telescope on Aug. 15, 2013 a-c, and the Gemini North telescope on Aug. 29, 2013 d.

The third closest star system to the sun, called WISE J104915.57-531906, center of large image, which was taken by NASA WISE. It appeared to be a single object, but a sharper image from Gemini Observatory, revealed that it was binary star system.

This composite, false-color infrared image of Jupiter reveals haze particles over a range of altitudes, as seen in reflected sunlight. It was taken using the Gemini North Telescope's Near-InfraRed Imager (NIRI) on May 18, 2017, in collaboration with the investigation of Jupiter by NASA's Juno mission. Juno completed its sixth close approach to Jupiter a few hours after this observation. The multiple filters corresponding to each color used in the image cover wavelengths between 1.69 microns and 2.275 microns. Jupiter's Great Red Spot (GRS) appears as the brightest (white) region at these wavelengths, which are primarily sensitive to high-altitude clouds and hazes near and above the top of Jupiter's convective region. The GRS is one of the highest-altitude features in Jupiter's atmosphere. Narrow spiral streaks that appear to lead into it or out of it from surrounding regions probably represent atmospheric features being stretched by the intense winds within the GRS, such as the hook-like structure on its western edge (left side). Some are being swept off its eastern edge (right side) and into an extensive wave-like flow pattern, and there is even a trace of flow from its northern edge. Other features near the GRS include the dark block and dark oval to the south and the north of the eastern flow pattern, respectively, indicating a lower density of cloud and haze particles in those locations. Both are long-lived cyclonic circulations, rotating clockwise -- in the opposite direction as the counterclockwise rotation of the GRS. A prominent wave pattern is evident north of the equator, along with two bright ovals, which are anticyclones that appeared in January 2017. Both the wave pattern and the ovals may be associated with an impressive upsurge in stormy activity that has been observed in these latitudes this year. Another bright anticyclonic oval is seen further north. The Juno spacecraft may pass over these ovals, as well as the Great Red Spot, during its close approach to Jupiter on July 10, 2017, Pacific Time (July 11, Universal Time). High hazes are evident over both polar regions with much spatial structure not previously been seen quite so clearly in ground-based images The filters used for observations combined into this image admit infrared light centered on the following infrared wavelengths (and presented here in these colors): 1.69 microns (blue), 2.045 microns (cyan), 2.169 microns (green), 2.124 microns https://photojournal.jpl.nasa.gov/catalog/PIA21713

Release Date April 1, 2009 This is an artistic illustration of the giant planet HR 8799b. The planet was first discovered in 2007 at the Gemini North observatory. It was identified in the NICMOS archival data in a follow-up search of NICMOS archival data to see if Hubble had also serendipitously imaged it. The planet is young and hot, at a temperature of 1500 degrees Fahrenheit. It is slightly larger than Jupiter and may be at least seven times more massive. Analysis of the NICMOS data suggests the planet has water vapor in its atmosphere and is only partially cloud covered. It is not known if the planet has rings or moons, but circumplanetary debris is common among the outer planets of our solar system. Credit: NASA/Goddard Space Flight Center/ESA/G.

The galaxy cluster called MOO J1142+1527 can be seen here as it existed when light left it 8.5 billion years ago. The red galaxies at the center of the image make up the heart of the galaxy cluster. This color image is constructed from multi-wavelength observations: Infrared observations from NASA's Spitzer Space Telescope are shown in red; near-infrared and visible light captured by the Gemini Observatory atop Mauna Kea in Hawaii is green and blue; and radio light from the Combined Array for Research in Millimeter-wave Astronomy (CARMA), near Owens Valley in California, is purple. In addition to galaxies, clusters also contain a reservoir of hot gas with temperatures in the tens of millions of degrees Celsius/Kelvin. CARMA was used to detect this gas, and to determine the mass of this cluster. http://photojournal.jpl.nasa.gov/catalog/PIA20052

WISE J104915.57-531906, center of the larger image, was taken by the NASA WISE. This is the closest star system discovered since 1916, and the third closest to our sun. It is 6.5 light-years away.

This infrared image, showing thermal radiation at a wavelength of 9.7 microns, was obtained by the Gemini North Telescope in Hawaii. The bright white and yellow features at bottom are the aftermath of an impactor hitting Jupiter on July 19, 2009.

Eight Looks at the Jupiter Impact

This Aug. 29, 2013, outburst on Io was among the largest ever observed on the most volcanically active body in the solar system. The infrared was image taken by Gemini North telescope.

This composite image shows a hot spot in Jupiter's atmosphere. In the image on the left, taken on Sept. 16, 2020, by the Gemini North telescope on the island of Hawaii, the hot spot appears bright in the infrared at a wavelength of 5 microns. In the inset image on the right, taken by Juno's JunoCam visible-light imager, also on Sept. 16 during Juno's 29th perijove pass, the hot spot appears dark. Scientists have known of Jupiter's hot spots for a long time. On Dec. 7, 1995, the Galileo probe likely descended into a similar hot spot. To the naked eye, Jupiter's hot spots appear as dark, cloud-free areas in Jupiter's equatorial belt, but at infrared wavelengths, which are invisible to the human eye, they are extremely bright, revealing the warm, deep atmosphere below the clouds. High-resolution images of hot spots such as these are key both to understanding the role of storms and waves in Jupiter's atmosphere. Citizen scientist Brian Swift processed the images to enhance the color and contrast, with further processing by Tom Momary to map the JunoCam image to the Gemini data. The international Gemini North telescope is a 26.6-foot-diameter (8.1-meter-diameter) optical/infrared telescope optimized for infrared observations, and is managed for the NSF by the Association of Universities for Research in Astronomy (AURA). https://photojournal.jpl.nasa.gov/catalog/PIA24299

Jupiter's banded appearance is created by the cloud-forming "weather layer." In this composite image, the image on the left show's Jupiter's thermal energy being emitted in infrared light, with dark cloudy bands appearing as silhouettes against Jupiter's thermal glow. The image on the right shows Jupiter's appearance in visible light, with white cloudy "zones" and the relatively cloud-free "belts" appearing as red-brown colors. The composite was created using infrared data collected by the Gemini North telescope (left) and a visible-light image taken by NASA's Hubble Space Telescope. Both images were created from data captured on Jan. 11, 2017. https://photojournal.jpl.nasa.gov/catalog/PIA24818
