Wide-field view of the Andromeda Galaxy showing the extent of the PHAT survey: This wide-field view shows the Andromeda Galaxy (Messier 31) along with its companions M32 (below centre) and NGC 205 (upper right). The extend of the new PHAT survey of Andromeda using the NASA/ESA Hubble Space Telescope is shown by the irregularly shaped region and the main image presented here by the rectangle within it.

Annotated section of Hubble image of the Andromeda Galaxy: This detailed image from the NASA/ESA Hubble Space Telescope shows a section of the Andromeda Galaxy, Messier 31, and marks a few of the many features that are revealed within it. Several object types are labelled, including dust lanes, stellar clusters, Milky Way stars, and star-forming regions.

Hubble image of NGC 7714: NGC 7714 is a spiral galaxy 100 million light-years from Earth — a relatively close neighbour in cosmic terms. The galaxy has witnessed some violent and dramatic events in its recent past. Tell-tale signs of this brutality can be seen in NGC 7714's strangely shaped arms, and in the smoky golden haze that stretches out from the galactic centre — caused by an ongoing merger with its smaller galactic companion NGC 7715, which is out of the frame of this image.

Name: Arp 284, NGC 7714
Type: Local Universe : Galaxy : Type : Interacting

Constellation: Pisces

Wide-field image of NGC 7714 (ground-based image): This image from the Digitized Sky Survey shows galaxy NGC 7714 and its surroundings. This galaxy is in the process of merging with its neighbour NGC 7715, which is also visible in this wide-field image. Together, these two form the merging pair Arp 284. In this image, the bright star you can see on the left is around a billion times closer than the galaxy.

Three moons and their shadows parade across Jupiter — Comparison of beginning and end of sequence, including annotations: These new NASA/ESA Hubble Space Telescope images capture a rare occurrence as three of Jupiter’s largest moons parade across the giant gas planet’s banded face. The image on the left shows the Hubble observation at the beginning of the event. On the left is the moon Callisto and on the right, Io. The shadows from Europa, which cannot be seen in the image, Callisto, and Io are strung out from left to right. The image on the right shows the end of the event, approximately 42 minutes later. Europa has entered the frame at lower left with slower moving Callisto above and to the right of it. Meanwhile Io — which orbits significantly closer to Jupiter and so appears to move much more quickly — is approaching the eastern limb of the planet. Whilst Callisto’s shadow seems hardly to have moved Io’s has set over the planet’s eastern edge and Europa’s has risen further in the west. The movement of the moons is shown in the video created from Hubble stills.
