Scientists have released the largest ever three-dimensional map of massive galaxies and distant black holes in our universe. The new map produced by Sloan Digital Sky Survey III pinpoints the locations and distances of over a million galaxies. It covers a total volume equivalent to that of a cube four billion light-years on a side.
This is one of the largest known structures in the neighbourhood of the universe, 4,000 million light-years away from Earth and roughly more than 10 billion years old, IUCAA said.
Her project aims to clean waste water by flowing through different layers of corn cobs which is a cost-effective and simple technique of cleaning water.
