Three Indian scientists– Sanjit Mitra, Tarun Souradeep and their graduate student Aditya Rotti — from the Inter- University Centre for Astronomy and Astrophysics (IUCAA), Pune, were a part of the team.

On March 21, the most-refined picture of the early cosmos after the Big Bang, measured by the European Space Agency’s Planck mission, was released at European Space Agency headquarters in Paris.

The map suggests that the universe is slightly older than thought. According to the map, subtle fluctuations in temperature were imprinted on the deep sky when the cosmos was about 370,000-years-old.

Planck also provided the most-precise measurements to date of tiny variations in the universe’s oldest light, called the cosmic microwave background (CMB), created more than 13 billion years ago when the universe was young—only a few hundred thousand-years-old, Sanjit Mitra told .

These measurements allow exquisite estimates of the age, composition, geometry and fate…
