Art and Science: Best 2019 satellites images from NASA
A collection of pictures released by NASA from 2019 highlighting climate change and the beauty of the earth in an artistic look.
US space agency NASA has released a collection of pictures from 2019 that highlights climate change and the beauty of the Earth in an artistic look. These were captured by Earth-observing satellites and instruments on the International Space Station.
1. Sediments in Solway Firth: It is the third-largest estuary (tidal mouth of a large river where the tide meets stream) in the southwest coast of Scotland in the UK. The image was captured by Operational Land Imager (OLI) on the Landsat 8 satellite on October 2, 2019.
2. The Wake of Tropical Cyclone Idai: The image was captured after one of the deadliest storms ever recorded Tropical Cyclone Idai in Southern Hemisphere. It caused flooding, landslides and hundreds of casualties across Mozambique, Malawi and Zimbabwe. One of the most affected areas was Beira, the second-largest port city in Mozambique. Around a million people were without electricity in Mozambique and the image, taken on March 24, shows that. It was captured using Suomi NPP satellite managed by NASA and the National Oceanic and Atmospheric Administration (NOAA).
3. Lena River Delta in Siberia: The image shows the wetland of the Lena River Delta. The wetland stretches from northeast Siberia and ends at the Arctic Ocean. The image was captured after the wetland was encased in snow and ice for seven months. It was captured on June 4, 2019, by OLI on Landsat 8. These types of images help in observing how seasons affect water resources.
4. Fires in Paraguay, Bolivia and Brazil: The image captures fire near the border of Bolivia, Paraguay and Brazil. It was taken using Landsat 8 satellite in August 2019. The black areas seen in the images show the burned areas.
Satellite-based forest monitoring system plays an important role in slowing deforestation by increasing awareness, starting actions through data.
5. Flash Drought in the Southeast United States:
Flash droughts bring a combination of unusually warm temperatures, low humidity and windy conditions that dry out the soil quickly. The image captured between September 10 and October 8, reveals the peak drought time in the region.
The region was observed using NOAA’s geostationary satellites, leaf area index data from Terra and Aqua satellites and the VIIRS on Suomi NPP.
6. Ash and Snow in Shiveluch: The Ring of Fire located in Kamchatka Peninsula is one of the most active zones on the planet. There are more than 300 volcanos on the peninsula out of which 29 are active.
The image captured on April 10, 2019, shows Shiveluch volcano erupting volcanic gas and ash in an area around 5 miles (8 kilometres) in Siberia. The eruption lasted 13 hours and left a signature on the snow below.
Various satellites captured the event including the OLI on Landsat 8.
7. Four Tropical Cyclones from Space: The image captured on September 4, 2019, shows a chain of tropical cyclones in the Western hemisphere. Scientists use Earth satellites to predict where they are headed.
8. Dust Storm in Southern Africa: One September 25, the skies of the west coast of Namibia and South Africa turned red as a dust storm passed over them. It was observed using VIIRS on the Suomi NPP satellite.
A dust storm is one of the indicators of climate change and satellites can also help in tracking the movement of the dust.
9. Clouds Over the North Pole: Unusual streaks of clouds form during sunset in the Northern hemisphere as the summer arrives. These clouds were captured on June 12, 2019. The data captured in the image measure the light reflected back into the space.
10. Total Solar Eclipse in the South Pacific: This image shows a total solar eclipse captured in the South Pacific, Chile and Argentina on July 2, 2019. It is a phenomenon when the moon comes in between the Sun and Earth, creating an eclipse. It was visible from a small area on the Earth and the exact same spot on Earth witnessed a solar eclipse for a few minutes after 375 years.
