A slice through the 3D map of galaxies from the first few months of the DESI survey. The Earth is at the center, with the furthest galaxies plotted at distances of 10 billion light-years. Each point represents one galaxy. This version of the DESI map shows a subset of 400,000 of the 35 million galaxies that will be in the final map. Image credit: D.

This image shows NGC 3318, a barred spiral galaxy some 115 million light-years away in the constellation of Vela. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) and VLT’s Multi Unit Spectroscopic Explorer (MUSE) instrument in the near-infrared and optical parts of the spectrum. Six filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This graphic shows X-rays that NASA’s Chandra X-ray Observatory detected from the dwarf galaxy Mrk 462. This X-ray emission (inset) is important because it reveals the presence of a growing supermassive black hole within this relatively small galaxy. The mass contained in this black hole -- about 200,000 times the mass of the Sun -- provides information to astronomers about how some of the earliest black holes in the Universe may have formed and grown billions of years ago. The background panel is an optical image from the Pan-STARRS telescope in Hawaii. There are several galaxies that are part of the HCG068 galaxy group on the left-hand side of the image. The galaxy that is emitting copious amounts of X-rays, however, is the much smaller galaxy located to the lower right of the image (marked by the arrow).

The Flame Nebula is the large feature on the left half of the central, yellow rectangle. The smaller feature on the right is the reflection nebula NGC 2023. To the top right of NGC 2023, the iconic Horsehead Nebula seems to emerge heroically from the ‘flames.’ The three objects are part of the Orion cloud, a giant gas structure located between 1,300 and 1,600 light-years away. The different colors indicate the velocity of the gas. The Flame Nebula and its surroundings are moving away from us, with the red clouds in the background receding faster than the yellow ones in the foreground. Image credit: ESO / Thomas Stanke / J. Emerson / VISTA / Cambridge Astronomical Survey Unit.
