Why in news: The India Meteorological Department (IMD) reported the advancement of the southwest monsoon into Maharashtra, Karnataka, Goa, Andhra Pradesh, Mizoram, and Manipur.
The IMD reported heavy rainfall in Kerala, Meghalaya, Andaman and Nicobar islands, Odisha, and Bihar since Friday due to an upper-air circulation off the Kerala coast. Heavy rainfall is predicted for the next five days in Kerala, Karnataka, Mahe, Tamil Nadu, Puducherry, and Karaikal.

Why in news: An international team led by Durham University discovered a vast ancient landscape of 31 flat surfaces formed by rivers buried beneath the East Antarctic Ice Sheet.
The discovery was made using the British Antarctic Survey's airborne radar technology to map bedrock beneath the ice. These surfaces were formed by rivers that flowed across the continent before being covered by ice approximately 80 million years ago.
