Dormant black hole suddenly becomes active to devour passing star; X-rays from inner part of disk baffle scientists

Supermassive Black Hole
Astronomers from the University of Michigan and University of Maryland have for the first time mapped the flow of gas near a supermassive black hole, Swift J1644+57, that woke from its dormant state to destroy and devour a star that drifted close to it. The astronomers are the first to document X-rays bouncing from deep within the walls of the black hole’s newly-formed accretion disk after a tidal disruption event.

Asteroid that made dinosaurs extinct nearly wiped out mammals too

New research has revealed that a prehistoric asteroid nearly wiped out all mammals along with dinosaurs. New data received has also revealed that the extinction was far more catastrophic than previously believed, although the species recovered rapidly from the mass extinction.
Distant Galaxy

Oxygen found in distant galaxy, 13.1 billion light years away; Discovery may pinpoint the origin of life-giving molecules

Scientists have detected life-giving gas oxygen in a faraway galaxy, 13.1 billion light years away. This could well be the oldest oxygen ever detected in the universe. The galaxy in question, SXDF-NB1006-2, is causing a storm in the scientific kingdom. Scientists are seeing the galaxy as it was 700 million years after birth of the universe. It shows the oldest signs of oxygen and this has baffled scientists.
Farming Technique

West Africa's ancient farming technique adds magic touch to climate change mitigation

A 700-year-old farming technique that was practised by villagers in West Africa could well be the answer to combating climate change and revolutionising farming across Africa. This centuries old technique converts nutrient-poor rainforest soil into fertile farmland. It may reduce food shortages in some of the poorest regions on Earth.
The Arctic tern

The Arctic tern sets world record by flying twice round the world

An Arctic tern, which measures 11-15 inches in length and weighs about a 100 grams, has set the record straight for the longest migration trip ever recorded. As Arctic terns can live for 15 to 30 years, they can cover over three million kilometres over its lifetime, which is roughly equivalent to four round trips to the moon.
