NASAさんのインスタグラム写真 - (NASAInstagram)「Take a look at this galactic monster mash! The exceptional galaxy cluster eMACS J1353.7+4329 lies about eight billion light-years from Earth in the constellation Canes Venatici. This disturbed collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens. The data in this image are drawn from an observing proposal called Monsters in the Making, which used two of @NASAHubble's instruments to observe five exceptional galaxy clusters at multiple wavelengths. These multi-wavelength observations were made possible by Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys. Learn more at the link in our bio! Image Description: A cluster of elliptical galaxies, visible as a dense crowd of oval shapes, each glowing orange around a bright core. Right of the largest, central galaxy, a background galaxy is stretched into two connected, thin arcs by the cluster’s gravity. Various other galaxies are dotted all around, a few being small spirals. A bright star with four long spikes stands out at the right.」7月15日 4時30分
