This image of NGC 3344 is a composite of separate exposures acquired by Hubble’s Wide Field Camera 3 (WFC3). Seven filters were used to sample various wavelengths. They cover wavelengths from the ultraviolet to the optical and the near-infrared. Together they create a detailed picture of the galaxy and allow astronomers to study many different aspects of it.

This illustration shows a glowing stream of material from a star, disrupted as it was being devoured by a supermassive black hole. When a star passes within a certain distance of a black hole -- close enough to be swallowed up -- the stellar material gets stretched and compressed as it is pulled in. A black hole’s destruction of a star, called ‘stellar tidal disruption,’ releases an enormous amount of energy, brightening the surroundings in an event called a flare.

This image from the NASA/ESA Hubble Space Telescope shows ACT-CLJ0102-4915. Massive galaxy clusters such as ACT-CLJ0102-4915 are useful tools for studying very distant objects, because this lens-like behavior amplifies the light from faraway galaxies in the background. They also contribute to a range of topics in cosmology, as the precise nature of the lensed images encapsulates information about the properties of spacetime, the expansion of the cosmos and the distribution of dark matter within the cluster.
