Over photos of celestial bodies, a line sweeps down and to the right.
Text: News from the Universe. November 17, 2022. Early-Universe Supernova. In a Hubble image, flecks of light glimmer around a supernova. Text: NASA's Hubble Space Telescope has captured the first detailed look at a supernova in the early universe. The Hubble photo slowly rotates.
In an animation, one straight line framed by two curved lines meet a flat surface. Text: The supernova's light passed through space that was warped by the gravity of a massive galaxy cluster. In the animation, the flat surface rotates. On the back of the surface, light swirls in a ring formation.
Text: Due to the warping, multiple images of the supernova over different time periods all arrived at Earth at once and were captured in one Hubble image.
A photo of Galaxy Cluster Abell 270 appears. Insets reveal photos of four different images of the lensed galaxy and supernova that form the Hubble image.
Text: The images show the supernova fading and its temperature changing. In a photo, circles mark 1 (day 0), 2 (day 2) and 3 (day 8). Text: A very early phase of the supernova appears blue, which is hotter. In the image, a circled area indicating day two appears blue.
Text: As the supernova cooled, its light turned redder. In the image, a circled area indicating day 8 appears redder.
Text: Scientists plan to build a catalog of early-universe supernovas, to better understand the young universe and its stars.
The Hubble image of the early-universe supernova appears. Text: This news was brought to you in part by the Space Telescope Science Institute in Baltimore, Maryland.
