Research on the Deniliquin structure points to an asteroid impact that would have been more than double the scale of the one that killed the dinosaurs.
The Double Asteroid Redirection Test successfully showed that it is possible to crash a spacecraft into a small asteroid and change its orbit. This technique could save Earth from asteroids in the future.

While current extinction rates remain lower than during previous mass extinction events, the number of species under threat of dying out is growing, reflecting the true scale of loss.
Huge volcanic eruptions were once believed to be the cause of mass extinctions on Earth. However, new research has found that super eruptions did not necessarily result in mass extinctions.
66 million years ago, birds survived the calamity that wiped out all prehistoric dinosaurs. But could birds once again evolve into their long lost ancestors?
The end-Triassic mass extinction was a cataclysm for the world’s prehistoric species, killed off by volcanoes that altered Earth’s seas and skies. But new research shows it didn’t happen when we thought.
