Eye on Infinity: NASA Celebrates Hubble’s 35th Year in Orbit

In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy.

Composite shows four Hubble images in quarters. At top left is a crisp view of Mars in shades of orange, blues, and browns. At top right is planetary nebula NGC 2899, which is shaped like a single macaroni noodle, with its central torus appearing semi-transparent and blue and green, and its top and bottom edges in orange. At bottom left is a tiny portion of the Rosette Nebula. Very dark gray material shaped like a triangle takes up the center. At bottom right is barred spiral galaxy NGC 5335 with a milky yellow center that forms a bar surrounded by multiple blue star-filled spiral arms that wrap up counterclockwise.
