Stereo image of the Veil Nebula: This is a stereo image of the Veil Nebula, using observations made by the NASA/ESA Hubble Space Telescope in 1997 and in 2015. If looked at them cross-eyed these two-dimensional images are then combined by the brain to give the perception of 3D depth. This illusion is created due to the movements of the filaments between the two observations.

Hubble and VLT images of the disc around AU Microscopii: Using images from the NASA/ESA Hubble Space Telescope and ESO’s Very Large Telescope, astronomers have discovered fast-moving wave-like features in the dusty disc around the nearby star AU Microscopii. These odd structures are unlike anything ever observed, or even predicted, before now. The top row shows a Hubble image of the AU Mic disc from 2010, the middle row Hubble from 2011 and the bottom row is an image taken with the SPHERE instrument, mounted on the Very Large Telescope, from 2014. The black central circles show where the brilliant light of the central star has been blocked off to reveal the much fainter disc, and the position of the star is indicated schematically. The scale bar at the top of the picture indicates the diameter of the orbit of the planet Neptune in the Solar System (60 AU). Note that the brightness of the outer parts of the disc has been artificially brightened to reveal the faint structure.

Ground-based view of the sky around the nearby star AU Microscopii: , This image shows the sky around the nearby young star AU Microscopii. It was created from images forming part of the Digitized Sky Survey 2. AU Mic appears just below the centre of the image as an orangish star of moderate brightness. Because the photographs through different coloured filters that were used to make this picture were taken many years apart, AU Mic appears double, as the star’s own proper motion has moved it a small distance across the sky in the intervening time.

Hubble Frontier Fields view of MACSJ0416.1–2403: This image from the NASA/ESA Hubble Space Telescope shows the galaxy cluster MACS J0416.1–2403. This is one of six being studied by the Hubble Frontier Fields programme, which together have produced the deepest images of gravitational lensing ever made. Due to the huge mass of the cluster it is bending the light of background objects, acting as a magnifying lens. Astronomers used this and two other clusters to find galaxies which existed only 600 to 900 million years after the Big Bang.

Hubble Frontier Fields view of MACSJ0717.5+3745: This image from the NASA/ESA Hubble Space Telescope shows the galaxy cluster MACSJ0717.5+3745. This is one of six being studied by the Hubble Frontier Fields programme, which together have produced the deepest images of gravitational lensing ever made. Due to the huge mass of the cluster it is bending the light of background objects, acting as a magnifying lens. It is one of the most massive galaxy clusters known, and it is also the largest known gravitational lens. Of all of the galaxy clusters known and measured, MACS J0717 lenses the largest area of the sky.

Hubble Frontier Fields view of Abell 2744: Abell 2744, nicknamed Pandora’s Cluster, was the first of six targets within the Frontier Fields programme, which together have produced the deepest images of gravitational lensing ever made. The cluster is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters.

Third appearance of the Refsdal supernova: This image composite shows the search for the supernova, nicknamed Refsdal, using the NASA/ESA Hubble Space Telescope. The image to the left shows a part of the the deep field observation of the galaxy cluster MACS J1149.5+2223 from the Frontier Fields programme. The circle indicates the predicted position of the newest appearance of the supernova. To the lower right the Einstein cross event from late 2014 is visible. The image on the top right shows observations by Hubble from October 2015, taken at the beginning of observation programme to detect the newest appearance of the supernova. The image on the lower right shows the discovery of the Refsdal Supernova on 11 December 2015, as predicted by several different models.

Illustration showing gravitational lensing producing supernova images: This illustration shows how the different images of the Refsdal supernova were created by the huge galaxy cluster MACS J1149.5+2223 in front of it. The light of the Supernova has been magnified and distorted due to gravitational lensing. This effect made the supernova and its host galaxy visible at three different locations. One of these images was again lensed by an elliptical galaxy within the galaxy cluster, which led to the creation of a formation known as an Einstein cross. This was observed in late 2014.
