![]() ![]() Light green colors in the image indicate deciduous forest, while dark green represents evergreen forests. Despite its name, the city is around 2700 km south of Earth’s geographic North Pole and around 200 km south of the Arctic Circle. Around 20 km from Fairbanks lies the city of North Pole. The highest mountain in North America, the Denali, lies in the Alaska Range and reaches an elevation of over 6000 m (not visible). The mountain range can sometimes be seen from Fairbanks on clear days. One of the components of the Alaskan mountains, the Alaska Range extends for around 650 km in a generally east-west arc from the Aleutian Range to the boundary of Yukon. South of the Tanana River lies the Tanana Flats, an area of marsh and bog that stretches for more than 160 km until it rises into the Alaska Range. The sediment-laden Tanana is rich in minerals, which gives it its milky color. The river drains the north slopes of the high Alaska Range and is fed by several glaciers. The river flows in a northwest direction along the base of the Alaska Range (visible in the bottom of the image) before joining the Yukon River near the village of Tanana. This image, captured on 11 September 2021, is also featured on the Earth from Space video program (image credit: Many low streams and rivers flow into the Tanana River. Dominating this week’s image, the Tanana River’s name is an Athabascan word meaning ‘river trail’. 2)įigure 2: Visible in the top-left corner of the image, Fairbanks is located in the central Tanana Valley, straddling the Chena River near its confluence with the Tanana River – a 940 km tributary of the Yukon River. December 10, 2021: The city of Fairbanks, the largest city in the Interior region of Alaska, and its surroundings, are featured in this Copernicus Sentinel-2 image.Find out more about Webb in ESA’s launch kit and interactive brochure. Webb is a joint project between NASA, ESA and the Canadian Space Agency (CSA). This will be used to detect the faint light of distant stars and galaxies with a sensitivity of a hundred times greater than that of Hubble. In the first month after launch, Webb will unfold its sunshield, which is around the size of a tennis court, and deploy its 6.5-meter primary mirror. This image is also featured on the Earth from Space video program (image credit: ESA) Its muddy waters appear brown most likely due to sediments picked up from the surrounding forest. The town lies at the estuary of the Kourou River which, after its journey of 144 km, empties into the Atlantic Ocean. Webb will see farther into our origins – from the Universe's first galaxies, to the birth of stars and planets, to exoplanets.įigure 1: Located around 60 km northwest of the French Guyanese capital Cayenne, Kourou is a coastal town in the north-central part of the country and is visible in the lower right of the image. The telescope will be able to detect infrared light generated by galaxies as they formed more than 13.5 billion years ago, in the aftermath of the Big Bang. Following the footsteps of the Hubble Space Telescope, Webb is designed to answer questions about the Universe and to make breakthrough discoveries in all fields of astronomy. After liftoff, it will embark on a month-long journey to its destination, around one and a half million kilometers from Earth. From here, the largest and most powerful telescope ever launched into space – the James Webb Space Telescope – is scheduled for launch. This launch base and the jungle that surrounds it covers 690 km 2 and protects an abundance of wildlife and plants. In addition, there is no risk of cyclones or earthquakes. As Kourou lies just 500 km north of the equator, it makes it ideally placed for launches into orbit as the rockets gain extra performance thanks to a ‘slingshot effect’ from the speed of Earth’s rotation. Just northwest of Kourou lies Europe’s Spaceport – chosen as a base from which to launch satellites in 1964 by the French Government, and currently home to ESA-developed rocket families Ariane and Vega. The surrounding area’s economy is largely agricultural, with coffee, cacao and tropical fruits being grown. ![]() Long, white sandy beaches line the town’s ocean coast, while the riverbank and inland area consists mostly of mangrove and dense tropical rainforest. December 17, 2021: Ahead of the upcoming Ariane 5 launch of the James Webb Space Telescope, the Copernicus Sentinel-2 mission takes us over Kourou – home to Europe’s Spaceport in French Guiana, an overseas department of France.Sentinel-2 imagery in the period 2021 References
