Mont Saint-Michel, France | European Space Agency

The Copernicus Sentinel-2 mission takes us over the Bay of Mont Saint-Michel in northern France. Lying between Brittany to the west and Normandy to the east, this remarkable bay, which is listed as a UNESCO world heritage site, sees some of the biggest tides in continental Europe. There can be up to 15 meter difference between low and high water. When spring tides peak, the sea recedes about 15 km from the coast and when it returns it does so very quickly, making it a dangerous place to be. Sentinel-2 captured this image when the tide was out so that the vast area of sand dunes is exposed cut by meandering channels of shallow water. Three rivers empty into the bay: the Couesnon, the Sée and the Sélune.

The famous rocky islet of Mont Saint-Michel, visible as a small dark spot in the south of the bay, is about 1 km from the mouth of the Couesnon. Home to a Benedictine monastery and village, Mont Saint-Michel is also a UNESCO world heritage site and a mecca for tourists.

The bay, however, has been prone to silting up in the last couple of centuries. Actions by man, including farming and the building of a causeway to the island monastery, have added to this problem. A major campaign has ensured that Mont-Saint-Michel preserves its maritime character and remains an island. The main river into the bay, the Couesnon, for example, is being left to flow more freely so that sediments are washed out to sea.

This image, which was captured on June 21, 2017, is also featured on the "Earth from Space" video program.

International Space Station Crew Spacewalk to Change Cooling Components | NASA

May 16, 2018: Outside the International Space Station, Expedition 55 NASA Flight Engineers Drew Feustel and Ricky Arnold conducted a spacewalk May 16 to swap out a failed cooling system component called a pump flow control subassembly (PFCS) for a spare. The PFCS is one of several on the truss structure of the station designed to regulate the flow of ammonia coolant through the cooling loops on the station to maintain the proper temperature for critical systems. It was the 210th spacewalk in support of space station assembly, maintenance and upgrades, the eighth in Feustel’s career and the fourth for Arnold.

Ricky Arnold's Spacewalk | International Space Station

Ricky: "An amazing view of our one and only planet."
NASA Astronaut Ricky Arnold takes a brief moment for a picture.
Expedition 55 Flight Engineers Drew Feustel and Ricky Arnold of NASA completed the fifth spacewalk of this year at 2:10 p.m. EDT, lasting 6 hours, 31 minutes. The two astronauts moved the Pump Flow Control Subassembly (PFCS) from a spare parts platform on the station’s truss to the Dextre robotic arm. The PFCS drives and controls the flow of ammonia through the exterior portions of the station’s cooling system. The team then removed and replaced a camera group and a degraded Space to Ground Transmitter Receiver Controller, and was also able to complete several get-ahead tasks.

Spacewalkers have now spent a total of 54 days, 16 hours and 40 minutes working outside the station in support of assembly and maintenance of the orbiting laboratory.

The Great Lakes | International Space Station

NASA Astronaut Ricky Arnold: "The Great Lakes looking grand on a clear spring day."

The Great Lakes, also called the Laurentian Great Lakes and the Great Lakes of North America, are a series of interconnected freshwater lakes located primarily in the upper mid-east region of North America, on the Canada–United States border, which connect to the Atlantic Ocean through the Saint Lawrence River. They consist of Lakes Superior, Michigan, Huron (or Michigan–Huron), Erie, and Ontario. The Great Lakes is the largest group of freshwater lakes on Earth by total area, and second largest by total volume containing 21% of the world's surface fresh water by volume. (Source: Wikipedia)

Dwarf Galaxy UGCA 281 | Hubble

UGCA 281 is a blue compact dwarf galaxy located in the constellation of Canes Venatici. Within it, two giant star clusters appear brilliant white and are swaddled by greenish hydrogen gas clouds. These clusters are responsible for most of the recent star formation in UGCA 281; the rest of the galaxy is comprised of older stars and appears redder in color. The reddish objects in the background are background galaxies that appear through the diffuse dwarf galaxy.

The image is a composite using both ultraviolet light and visible light, gathered with Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys.

Dwarf Galaxy DDO 68: Star formation | Hubble

The dwarf galaxy DDO 68, also known as UGC 5340, lies about 40 million light-years away from Earth. Due to its proximity it became one of the 50 targets of LEGUS.

In UGC 5340, a pocket of rapid star birth appears in the lower right corner. This region of star formation was probably triggered by a gravitational interaction with an unseen companion galaxy. But star formation is present across the entire body of UGC 5340, and the relatively young stars are responsible for the galaxy’s blue-white color.

An image of this galaxy was already released back in 2014. This newly-processed image now also shows ultraviolet radiation Hubble captured from the galaxy.

Spiral Galaxy Messier 106 | Hubble

Messier 106, also known as NGC 4258, is a relatively nearby spiral galaxy, a little over 20 million light-years away. This makes it one of the nearest spiral galaxies.
Despite carrying his name, Messier 106 was neither discovered nor cataloged by the renowned 18th-century astronomer Charles Messier. Discovered by his assistant, Pierre Méchain, the galaxy was never added to the Messier catalog in his lifetime. Along with six other objects discovered but not logged by the pair, Messier 106 was posthumously added to the catalog in the 20th century.

An image of this galaxy was already released back in 2013. This newly-processed image now also shows ultraviolet radiation Hubble captured from the galaxy.

Galaxy Messier 66—member of the Leo Triplet | Hubble

The spiral galaxy Messier 66 is located at a distance of about 35 million light-years in the constellation of Leo (The Lion). Together with Messier 65 and NGC 3628, Messier 66 is a member of the Leo Triplet, a trio of interacting spiral galaxies.

Like all the galaxies in LEGUS, Messier 66 is undergoing vigorous star and star-cluster formation. One of the goals of LEGUS is to sample star-forming regions across each galaxy. Because the galaxies are relatively close to Earth, Hubble can resolve individual stars.

An image of this galaxy was already released back in 2010. This newly-processed image now also shows ultraviolet radiation Hubble captured from the galaxy.

Wave of star formation in Galaxy Messier 96 | Hubble

Messier 96, also known as NGC 3368, is a spiral galaxy about 35 million light-years away in the constellation of Leo (The Lion). It is of about the same mass and size as the Milky Way. It was first discovered by astronomer Pierre Méchain in 1781, and added to Charles Messier’s famous catalog of astronomical objects just four days later.

A wave of star formation is occurring along the dark filaments that make up the spiral arms. The fledgling stars illuminate the surrounding hydrogen gas, making the stars appear pink. Star birth begins at the inner spiral arms and moves outward. The milky white regions in the center of these galaxies represent the glow of countless stars.

An image of this galaxy was already released back in 2015. This newly-processed image now also shows ultraviolet radiation Hubble captured from the galaxy.
