$This Hubble image shows the dwarf starburst galaxy ESO 495-21. The galaxy is just 3,000 light-years across, a fraction of the size of the Milky Way, but that is not stopping the galaxy from furiously forming huge numbers of stars. This image is a composite of separate exposures acquired by Hubble’s Wide Field Planetary Camera 2 (WFPC2) and Advanced Camera for Surveys (ACS) instruments. Image credit: NASA / ESA / Hubble.$

This image of the irregular galaxy NGC 4485 was made from separate exposures taken in the visible region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). NGC 4485 has been involved in a dramatic gravitational interplay with its larger galactic neighbor, NGC 4490, out of frame to the bottom right in this image. This ruined the original, ordered spiral structure of the galaxy and transformed it into an irregular one. Below NGC 4485 one can see a bright, orange background galaxy: CXOU J123033.6+414057. This galaxy is the source of X-ray radiation studied by NASA’s Chandra X-ray Observatory. It’s distance from Earth is about 850 million light-years. Image credit: NASA / ESA / Hubble.

Astronomers developed a mosaic of the distant Universe -- called the Hubble Legacy Field -- that documents 16 years of observations from the NASA/ESA Hubble Space Telescope. The image contains nearly 265,000 galaxies that stretch back through 13.3 billion years of time to just 500 million years after the Big Bang. The new set of Hubble images, created from nearly 7,500 individual exposures, is the first in a series of Hubble Legacy Field images. Image credit: NASA / ESA / G. Illingworth & D.

These 210 images reflect Rosetta’s ever-changing view of Comet 67P/Churyumov-Gerasimenko between July 2014 and September 2016. The sequence begins in the month leading up to Rosetta’s arrival on August 6, 2014, when the comet was barely a few pixels in the field of view. Suddenly, the curious shape was revealed and Rosetta raced to image its surface, coming within 10 km, to find a suitable place for Philae to land just three months later. Philae’s landing is featured with the ‘farewell’ images taken by both spacecraft of each other shortly after separation, and by Philae as it drew closer to the surface at its first touchdown point. An image taken at the final landing site is also shown. The subsequent images, taken by Rosetta, reflect the varying distance from the comet as well as the comet’s rise and fall in activity as they orbited the Sun. Before the comet reached its most active phase in August 2015, Rosetta was able to make some close flybys, including one in which the lighting geometry from the Sun was such that the spacecraft’s shadow could be seen on the surface. Then, owing to the increase of dust in the local environment, Rosetta had to maintain a safer distance and carry out scientific observations from afar, but this also gave some impressive views of the comet’s global activity, including jets and outburst events. Once the activity began to subside, Rosetta could come closer again and conduct science nearer to the nucleus, including capturing more high-resolution images of the surface, and looking out for changes after this active period. Eventually, as the comet returned to the colder outer Solar System, so the available solar power to operate Rosetta fell. The mission concluded with Rosetta making its own dramatic descent to the surface on September 30, 2016. A selection of the final images taken are reflected in the last images shown in this montage.
