Sunbeam Rahman is a self-inspired dream guided GIS-RS analyst who has spent most of his life trying to decipher all the geospatial problems of the world but couldn't solve any. Sunbeam had his MS in 'Geography' and currently works at a 'grande entreprise gouvernementale'. Sunbeam spends most of his time either in his room reading fantasy novels or other peoples tweet, watching tv series or doing BS like blogging.

The long awaited digital AI system that can create realistic images and art from a description in natural language called Dall.E 2 is here. It is free to test, so I created an account to test out this amazing tool. Here are few more example from the same prompt (or did I use ‘headphones’ instead).
Today NASA unveiled first images from their flagship James Webb Space Telescope or JWST. This is an image of Carina Nebula, one of the largest and brightest nebulae that is visible in the night sky. It is located about 7,600 light-years away in the southern constellation of Carina.
Called the Cosmic Cliffs, JWST’s seemingly three-dimensional picture looks like craggy mountains on a moonlit evening. In reality, it is the edge of the giant, gaseous cavity within NGC 3324, and the tallest “peaks” in this image are about 7 light-years high. The cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located in the center of the bubble, above the area shown in this image.
The image above shows the Southern Ring Nebula, also called the “Eight-Burst,” which is 2,000 light-years away from Earth. Planetary nebulae are the shells of gas and dust ejected from dying stars. The image reveal details of the nebula that were previously hidden from astronomers.
This observation shows the Southern Ring Nebula almost face-on, but if we could rotate it to view it edge-on, its three-dimensional shape would more clearly look like two bowls placed together at the bottom, opening away from one another with a large hole at the center. The brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.
World Resources Institute and Google announced 10m resolution global land cover data called Dynamic World powered by Google Earth Engine and AI Platform. Dynamic World is a 10m near-real-time LULC dataset that includes nine classes and available for the Sentinel-2 L1C collection from 2015 until today. The image here is the land cover map of Dhaka which once took me many hours to produce is now just clicks away.
Dynamic World allows researchers to build their own maps based on the outputs of our machine learning model, a major advancement in map making. Researchers can combine local information with the data from Dynamic World to produce a new map, for example a map that analyzes crop harvests between particular dates. Dynamic World is also useful for understanding longer-term trends of seasonal ecosystem change, as seen in the Okavango Delta, an area that attracts thirsty wildlife when it floods in July and August and then dries from September to October.
On the onset of the 50th anniversary of independence, Bangladesh today announced electricity coverage all over the country. In this Google map, the night light shows the spread specially in the capital at the center. We can even find some of the India-Bangladesh border in the northwest and western part of the country.
