This image of a sunspot was taken on January 28, 2020 by NSF’s Inouye Solar Telescope’s Wave Front Correction context viewer. The image reveals striking details of the sunspot’s structure as seen at the Sun’s surface. The sunspot is sculpted by a convergence of intense magnetic fields and hot gas boiling up from below. This image uses a warm palette of red and orange, but the context viewer took this sunspot image at the wavelength of 530 nm -- in the greenish-yellow part of the visible spectrum.

This Hubble image shows NGC 1792, a spiral galaxy 36.4 million light-years away in the southern constellation of Columba. The vast swathes of tell-tale blue seen throughout NGC 1792 indicate areas that are full of young, hot stars, and it is in the shades of orange, seen nearer the center that the older, cooler stars reside. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. It is based on data obtained through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Data from more than 1.8 billion stars have been used to create this map of the entire sky. It shows the total brightness and color of stars observed by ESA’s Gaia satellite and released as part of Gaia’s Early Data Release 3. Brighter regions represent denser concentrations of bright stars, while darker regions correspond to patches of the sky where fewer and fainter stars are observed. The color of the image is obtained by combining the total amount of light with the amount of blue and red light recorded by Gaia in each patch of the sky. The bright horizontal structure that dominates the image is the plane of our Milky Way Galaxy. It is actually a flattened disk seen edge-on that contains most of the Galaxy’s stars. In the middle of the image, the Galactic center appears bright, and thronged with stars. Darker regions across the Galactic plane correspond to foreground clouds of interstellar gas and dust, which absorb the light of more distant stars. Many of these clouds conceal stellar nurseries where new generations of stars are currently being born. Dotted across the image are also many globular and open clusters, as well as entire galaxies beyond our own. The two bright objects in the lower right of the image are the Large and Small Magellanic Clouds, two dwarf galaxies orbiting the Milky Way. Image credit: ESA / Gaia / DPAC / CC BY-SA 3.0 IGO / A.
