The Indian Space Research Organisation (ISRO) has unveiled spectacular images of the Earth taken by its Earth Observation Satellite (EOS-06), also known as Oceansat-3. The satellite used its Ocean Colour Monitor (OCM) to capture the images, which reveal every continent and were taken between February 1 and 15, 2023. The stunning pictures were created by merging 2,939 images and processing 300 GB of data to produce a mosaic with a spatial resolution of 1 km. Different continents are visible in different colours due to variations in wavelengths.

ISRO has confirmed that the images contain information about global vegetation cover on land and ocean biota. The OCM is capable of sensing the Earth in 13 distinct wavelengths, making it a powerful tool for oceanography and atmospheric research. Oceansat-3 is a nanosatellite that was launched by ISRO in November 2022, as part of a larger constellation of satellites.
Oceansat-3 is equipped with three primary instruments: the Ocean Colour Monitor (OCM-3), the Sea Surface Temperature Monitor (SSTM), and the Ku-Band Scatterometer (SCAT-3), as well as the ARGOS system. The satellite can use chlorophyll and SST, wind speed, and land-based applications to identify potential fishing zones.
The images have been met with widespread awe and admiration from internet users, who have flooded social media with comments about the planet’s stunning beauty. Some people have even expressed pride in their own countries. The images have gone viral, with many users describing them as “mind-blowing” and a “feast for the eyes.”
The release of the images comes shortly after a tweet from NASA, which shared an old image of Earth at night that showed human settlements across the planet.
