The dry season in central Africa spans roughly May through September, with fire season peaking in July through August.ġkm (596.2 KB), 500m (1.8 MB), 250m (5. In the dry season, they set fires to clear brush and dead vegetation from farm and grazing land and to deal with household trash.

People in Africa have used fire for hundreds, possibly thousands, of years as an agricultural and land management tool. Credit: NASA Let’s take a look at the individual phases, and how the movements of the Moon and Sun appear to us as we watch from the Northern Hemisphere on Earth: New Moon This is the invisible phase of the Moon, with the illuminated side of the Moon facing the Sun and the night side facing Earth. Discover the cosmos Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Scientists use these images to track changes on Earths surface. NASA uses satellites in space to gather images like these over the whole world every day. The widespread nature of the fires, their location, and the time of year all suggest that people are intentionally setting most of these fires for agricultural purposes. These images show the Earths surface and clouds in true color, like a photograph.
Each red “hot spot” marks an area of actively burning fire, and they are abundant in Zambia (east), Democratic Republic of Congo (north and central), and Angola (west). EOSDIS makes the agency's large repository of data accessible and freely available to the public. Worldview is part of NASA’s Earth Observing System Data and Information System. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite acquired a true-color image spanning the continent from Lake Tanganyika to the Pacific Ocean. The NASA Worldview app provides a satellite's perspective of the planet as it looks today and as it has in the past through daily satellite images. Water is very dark, almost black, which makes it much easier to see lakes or flooded lands.Many hundreds of fires dotted central Africa in early June 2023. Notice how water and clouds in false-color images look very different than they do in true-color images. Over 50 different global datasets are represented with daily, weekly, and monthly snapshots, and images are available in a variety of formats.

Depending upon how high they are and how cold they are, clouds' colors range from white, to baby blue, to bright turquoise. Welcome to NASA Earth Observations, where you can browse and download imagery of satellite data from NASAs Earth Observing System. Ice and snow on the ground show up as bright turquoise. Cold things appear blue: the colder something is, the brighter blue it will look.
By assigning colors (red, green, or blue) to measurements of infrared light, we can see and understand the resulting pictures - called "false-color images." In the false-color images available in NEO, areas with plants look bright green while deserts look tan. Scientists use satellite sensors to measure how much infrared light Earth reflects back up into space. NASA uses satellites in space to gather images like these over the entire planet every day. 2020.11.23 Moon Phase and Libration, 2020 2019.12.12 Moon Phase and Libration, 2019 2018.12.15 Moon Phase and Libration, 2018 2017.12.18 Moon Phase and Libration, 2017 2016.12.22 Moon Phase and Libration, 2016 2015.12.10 Moon Phase and Libration, 2015 2014.12.09 Moon Phase and Libration, 2014 2013.12. Infrared light is invisible to our eyes, but not to satellites. The James Webb Space Telescope, NASA’s biggest, most expensive and powerful telescope to date, was launched in December 2021 with the intention of spending five to 10 years studying a plethora of things, including the formation of the universe’s earliest galaxies and the developments of our own solar system. That's because the images include more than just the red, green, and blue light that our eyes can see, but also infrared light.

The images might look a little funny, sort of like a TV picture that needs to be fixed. These images show Earth's surface and clouds in false colors.
