The image is a combination of exposures taken in visible and near-infrared light, using Hubble’s Advanced Camera for Surveys. The field of view is around 3.4 by 3.4 arcminutes, or around a tenth of the diameter of the full moon.

An artist's illustration of PH1, a planet discovered by volunteers from the Planet Hunters citizen science project. PH1, shown in the foreground, is a circumbinary planet and orbits two suns.

Nanoparticles of cobalt attach themselves to a graphene substrate in a single layer. As a catalyst, the cobalt-graphene combination was a little slower getting the oxygen reduction reaction going, but it reduced oxygen faster and lasted longer than platinum-based catalysts.

Images in the visible-light and infrared parts of the spectrum highlight the massive changes roiling the atmosphere of Jupiter.

Supernova remnant SNR1987A is located 166 000 light-years away in the Large Magellanic Cloud. The light from the stellar explosion arrived at Earth in 1987, and has since provided astronomers with a natural laboratory to monitor how the brightness of a supernova changes over time.
Dominating this Hubble Space Telescope view of the remnant are two glowing loops and a very bright ring of shocked hotspots surrounding the location of the now-exploded central star. The material making up these loops and rings was probably ejected from the star earlier in its history and is now being illuminated by the supernova and its shockwave.

NASA's Cassini spacecraft obtained this image of a feature shaped like a hot cross bun in the northern region of Titan (left) that bears a striking resemblance to a similar feature on Venus (right).
