Great Britain & Ireland Show Their Summer Colors | International Space Station

Great Britain & Ireland Show Their Summer Colors | International Space Station

An astronaut on the International Space Station took this photograph during a rare clear day over Ireland and Great Britain. The wide view captures the contrasting colors of various land cover types present across the two islands.

Coastal mountains and rough terrain flank the western edge of Ireland, making the peninsulas there appear browner than the more vegetated (green) areas of central Ireland. The central region is composed of plains with bogs and hilly lowlands, largely consisting of assorted forests, agriculture, and pastures. Similar green tones carry over to the western side of Great Britain.

Many of the tan areas on the eastern side of Great Britain are within a rain shadow created by the uplands and mountains to the west. Weather systems move from west to east, and higher elevation areas on the west receive more rainfall than the lower eastern side. The tan color reflects grasslands where the vegetation was stressed due to high temperatures and drought conditions when this image was taken in summer 2022.

Cities are scattered across both islands, visible as dark-gray and white areas. Great Britain has the highest population density in the region, as indicated by the spatially extensive urban and suburban colors around London, Birmingham, and Manchester.

Across both islands, more than 78,200 square kilometers (30,200 square miles) of land (24 percent) is dedicated to conservation. These areas protect over 10,000 habitats that are used for breeding, migration, and shelter to flora and fauna, such as wildfowl, bats, and mosses.

Astronaut photograph ISS067-E-253753 was acquired on August 11, 2022, with a Nikon D5 digital camera using an 17 millimeter lens and is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 66 crew.

Globular Cluster ESO 520-21 | Hubble

 Globular Cluster ESO 520-21 | Hubble

This sparkling starfield, captured by the NASA/European Space Agency Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6). A densely packed, roughly spherical collection of stars, it lies close to the center of the Milky Way, where interstellar gas and dust absorb starlight and make observations more challenging. 

Globular clusters (GCs) are spheroidal collections of tightly bound stars orbiting galaxies perceived as natural laboratories enabling studies on stellar and chemical evolution. These objects are relatively rare, as there are just over ~200 such clusters so far identified in the Milky Way.

This absorption by interstellar material affects some wavelengths of light more than others, changing the colors of astronomical objects and causing them to appear redder than they actually are. Astronomers call this process “reddening”, and it makes determining the properties of globular clusters close to the galactic center—such as ESO 520-21—particularly difficult.

ESO 520-21 lies in the constellation Ophiuchus, near the celestial equator. Ophiuchus was one of the 48 constellations which appeared in the writings of the second-century Egyptian astronomer Ptolemy, all of which are among the 88 constellations officially recognized by the International Astronomical Union today. Not all the constellations proposed by astronomers throughout history have survived, however—forgotten or obsolete constellations include Felis (the Cat), Rangifer (the Reindeer), and even Officina Typographica (the Printer’s Workshop).

A Well-traveled Beagle | NASA's Artemis I Moon Mission

A Well-traveled Beagle | NASA's Artemis I Moon Mission

Snoopy, the zero gravity indicator that flew aboard NASA's Orion spacecraft during the Artemis I mission, wears a smile after being unpacked from his transport case on Jan. 5, 2023. Zero gravity indicators are small items carried aboard spacecraft that provide a visual indicator when a spacecraft has reached the weightlessness of microgravity. NASA has held an association with Snoopy since the Apollo Era—the character has contributed to the excitement for NASA human spaceflight missions, helping inspire generations to dream big, and is a symbol of NASA’s safety culture and mission success.

Orion returned to Kennedy on Dec. 30, 2022, after splashing down in the Pacific Ocean on Dec. 11, 2022, following a 25-day mission around the Moon. 

After launching atop the Space Launch System (SLS) rocket on Nov. 16, 2022, from the agency’s Kennedy Space Center (KSC) in Florida, Orion spent 25.5 days in space before returning to Earth, completing the Artemis I mission. Orion stayed in space longer than any ship for astronauts has done without docking to a space station and returned home faster and hotter than ever before.

The Artemis I mission is the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, the SLS rocket, and Kennedy Space Center's Exploration Ground Systems.

The Great Lakes of North America Dressed for Winter | International Space Station

The Great Lakes of North America Dressed for Winter | International Space Station

On February 17 and 18, 2022, a strong winter storm brought snow, sleet, and rain to the Great Lakes area of the U.S. and Canada. An astronaut aboard the International Space Station snapped this photograph on February 20, 2022, after the storm.

At the time, the space station was orbiting directly over northern Iowa, but the oblique angle of the photo shows areas farther to the east including Michigan, Ontario, and the Great Lakes. Clouds still obscured parts of northern Michigan and Ontario, but clear skies prevailed in areas south. Notice the band of snow between Lake Huron and Lake Erie. This is where the storm dropped nearly 7 inches (18 centimeters) of snow in places.

The photograph also shows plenty of ice on Lake Huron—most notably in Saginaw Bay—and across much of Lake Erie. Almost one week later, ice cover on the Great Lakes reached its maximum extent for the 2021–2022 winter, measuring slightly above average (calculated since the start of record keeping in the early 1970s).

Ice on individual lakes can peak earlier or later depending on conditions that change daily. Lake Erie’s ice cover, for example, peaked late in January 2022 at 94 percent. It then dipped to 62 percent on February 3 and rose to 90 percent on February 5. By the time of this image on February 20, coverage had dropped to 81 percent. Quickly shifting ice cover is often a response to swift changes in wind conditions or air temperature.

The initiation of ice formation depends on factors such as the lake’s latitude, size, and depth. Notice in this image that Lake Michigan and Lake Ontario—significantly deeper lakes than Lake Erie—are still largely unfrozen. The exposed water on these lakes can provide the moisture for lake-effect snow. The phenomenon contributed to the huge accumulations of snow during a historic winter storm later in the year, when snowfall totals reached more than 50 inches (130 centimeters) in communities east of Lake Ontario and Lake Erie.

The Great Lakes, also called the Great Lakes of North America or the Laurentian Great Lakes, is a series of large interconnected freshwater lakes with sea-like characteristics in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. They are Lakes Superior, Michigan, Huron, Erie, and Ontario and are in general on or near the Canada–United States border. Hydrologically, there are four lakes, because lakes Michigan and Huron join at the Straits of Mackinac. 

The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume.

Astronaut photograph ISS066-E-147455 was acquired on February 20, 2022, with a Nikon D5 digital camera using a focal length of 24 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 66 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. 

The International Space Station Program supports the laboratory as part of the ISS National Lab to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public.

Cosmic Fireworks: Spiral Galaxy NGC 6984 | Hubble

Cosmic Fireworks: Spiral Galaxy NGC 6984 | Hubble

This NASA/European Space Agency Hubble Space Telescope image features the galaxy NGC 6984, an elegant spiral galaxy in the constellation Indus roughly 200 million light-years away from Earth. The galaxy is a familiar sight for Hubble, having already been captured in 2013. The sweeping spiral arms are threaded through with a delicate tracery of dark lanes of gas and dust, and studded with bright stars and luminous star-forming regions.

These new observations were made following an extremely rare astronomical event—a double supernova in NGC 6984. Supernovae are unimaginably violent explosions on a truly vast scale, precipitated by the deaths of massive stars. These events are powerful but rare and fleeting—a single supernova can outshine its host galaxy for a brief time. The discovery of two supernovae at virtually the same time and location (in astronomical terms) prompted speculation from astronomers that the two supernovae may somehow be physically linked. Using optical and ultraviolet observations from Hubble’s Wide Field Camera 3, astronomers sought to get a better look at the site of the two supernovae, hopefully allowing them to discover if the two supernova explosions were indeed linked. Their findings could give astronomers important clues into the lives of binary stars.

As well as helping to unravel an astronomical mystery, these new observations added more data to the 2013 observations, and allowed this striking new image to be created. The observations—each of which covers only a narrow range of wavelengths—add new details and a greater range of colors to the image.

Open Star Cluster in The Large Magellanic Cloud | Hubble

Open Star Cluster in The Large Magellanic Cloud | Hubble

This image shows an open cluster known as NGC 2164, which was first discovered in 1826 by a Scottish astronomer named James Dunlop. NGC 2164 is located within one of the Milky Way galaxy's closest neighbors—the satellite galaxy known as the Large Magellanic Cloud. The Large Magellanic cloud is a relatively small galaxy that lies about 160,000 light-years from Earth. It is considered a satellite galaxy because it is gravitationally bound to the Milky Way. In fact, the Large Magellanic Cloud is on a very slow collision course with the Milky Way—it is predicted that they will collide 2.4 billion years from now.

The Large Magellanic Cloud only contains about one hundredth as much mass as the Milky Way, but it still contains billions of stars. The open cluster NGC 2164 is in good company in the Large Magellanic Cloud—the satellite galaxy is home to roughly 700 open clusters, alongside about 60 globular clusters. This image of NGC 2164 was taken by the NASA/European Space Agency Hubble Space Telescope’s Wide Field Camera 3 (WFC3), which has previously imaged many other open clusters, including NGC 330 and Messier 11.

Cosmological Curiosity: Spiral Galaxy Mrk 1337 | Hubble

Cosmological Curiosity: Spiral Galaxy Mrk 1337 | Hubble

This image from the NASA/European Space Agency Hubble Space Telescope features the spiral galaxy Mrk 1337, which is roughly 120 million light-years away from Earth in the constellation Virgo. Hubble’s Wide Field Camera 3 snapped Mrk 1337 at a wide range of ultraviolet, visible and infrared wavelengths, producing this richly detailed image. Mrk 1337 is a weakly barred spiral galaxy, which as the name suggests means that the spiral arms radiate from a central bar of gas and stars. Bars occur in roughly half of spiral galaxies, including our own galaxy the Milky Way.

These observations are part of a campaign to improve our knowledge of how fast the universe is expanding. They were proposed by Adam Riess, who was awarded a Nobel Laureate in physics 2011 for his contributions to the discovery of the accelerating expansion of the Universe, alongside Saul Perlmutter and Brian Schmidt.

Cosmological Curiosity: Spiral Galaxy Mrk 1337 | Hubble

This image from the NASA/European Space Agency Hubble Space Telescope features the spiral galaxy Mrk 1337, which is roughly 120 million light-years away from Earth in the constellation Virgo. Hubble’s Wide Field Camera 3 snapped Mrk 1337 at a wide range of ultraviolet, visible and infrared wavelengths, producing this richly detailed image. Mrk 1337 is a weakly barred spiral galaxy, which as the name suggests means that the spiral arms radiate from a central bar of gas and stars. Bars occur in roughly half of spiral galaxies, including our own galaxy the Milky Way.

These observations are part of a campaign to improve our knowledge of how fast the universe is expanding. They were proposed by Adam Riess, who was awarded a Nobel Laureate in physics 2011 for his contributions to the discovery of the accelerating expansion of the Universe, alongside Saul Perlmutter and Brian Schmidt.
