GN-z11, a young but moderately massive galaxy located in the constellation of Ursa Major, is estimated to date from when the Universe was only 420 million years old, or 3% of its current age. This image shows GN-z11, a luminous star-forming galaxy at z = 10.957. Image credit: NASA / ESA / P. Oesch, Yale University / G. Brammer, STScI / P. van Dokkum, Yale University / G.

This Hubble images shows Caldwell 45, a spiral galaxy located 59 million light-years away in the constellation Boötes. Also known as NGC 5248, this galaxy is notable for the ring structure around its nucleus. These nuclear rings are characterized by hot spots of starburst activity. Caldwell 45 was discovered by astronomer William Herschel in 1784. The galaxy has an apparent magnitude of 10 and can be spotted using a small telescope, though it won’t appear very bright. A larger telescope is needed to make out the galaxy’s spiral arms. The best time of year to observe Caldwell 45 is during the northern hemisphere’s spring and the southern hemisphere’s autumn. This stunning image of Caldwell 45 is a composite of observations made by Hubble’s Wide Field Camera 3 (WFC3) and Wide Field and Planetary Camera 2 (WFPC2) in visible, infrared, and ultraviolet light. It captures the glowing red clouds where new stars are forming, scattered along the galaxy’s winding arms. These observations of Caldwell 45 were made to help astronomers learn more about gas in the galaxy’s starburst regions, as well as to better understand the structure of its nuclear rings.

This Hubble image shows GAL-CLUS-022058-38303, the largest, nearly-complete Einstein ring known. The image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

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.

As the CMB light (left image) travels through the Universe until observed on Earth (right image), the direction in which the electromagnetic wave oscillates (orange line) is rotated by the angle β; the rotation could be caused by dark matter or dark energy interacting with the CMB light, which changes the patterns of polarization (black lines inside the images); the red and blue regions in the images show hot and cold regions of the CMB, respectively.
