  Could a Supernova Threaten Earth’s Survival? Here's What You Need to Know

  Supernova explosions have the potential to harm Earth’s atmosphere, particularly the ozone layer. However, no stars close enough to cause damage are currently identified. The risks are low, but gamma-ray bursts, caused by neutron star mergers, may pose an even greater threat in the future.

  Future Supercontinent Pangea Ultima Could Trigger Mass Extinction, Reveals New Study

  A University of Bristol study warns that Earth’s future supercontinent, Pangea Ultima, may make the planet uninhabitable for humans and mammals. Due to a combination of rising CO₂ levels, increased solar radiation, and vast land area far from oceanic cooling, the supercontinent could experience widespread extreme temperatures. Though millions o...

  Continent Merger, Deadly Heat May Lead To Human Extinction: Study

  Extreme temperatures in future may potentially lead to the first mass extinction on Earth since the dinosaurs, a new study has revealed.

  El Nino and Massive Volcanic Eruptions Triggered Mass Extinction of Life 250 Million Years Ago

  The worst mass extinction in Earth's history, 250 million years ago, was triggered by extreme El Niño events and volcanic eruptions in Siberia. These eruptions released vast amounts of carbon dioxide into the atmosphere, causing severe climate changes. The warming environment led to the death of 90% of species on land and in the oceans. While this...

  Asteroid That Triggered Dinosaur Extinction Was a Carbon-Rich C-Type Space Rock, Study Finds

  Recent research has provided new insights into the asteroid that struck Earth 66 million years ago, causing a mass extinction event that led to the end of the dinosaurs. Scientists have now identified this impactor as a carbon-rich "C-type" asteroid, a type of space rock that likely originated in the asteroid belt between Mars and Jupiter.

  Global Warming Triggered Reptile Boom Millions of Years Ago: Says Study

  A new study indicates that global warming, rather than mass extinction was behind a boom in reptile population and diversity. Researchers, from the Department of Organismic and Evolutionary Biology and the Museum of Comparative Zoology at Harvard University, have revealed that the evolution of reptiles began much earlier than previously thought.

  Bigger Temperature Changes Linked to Larger Extinction Events, Japanese Researcher Claims

  Research by a professor emeritus in Japan has revealed that mass extinctions increase in proportion to climate change. The evidence revealed by the study shows a high correlation between the size of mass extinctions and historical fluctuations in the Earth's temperature.

  Dinosaur-Killing Asteroid May Have Hit Earth During Spring, Research Suggests

  The extinction of dinosaurs took place about 66 million years ago but we are yet to know the full impact of the asteroid that wiped out this species. Scientists are still studying the disaster and continuously unearthing new aspects of the devastating impact. Now, researchers say that if the asteroid's trajectory had been slightly different, it wou...

  'Shark-Toothed' Dinosaur That Competed With T-Rex Lived in Present Uzbekistan 90 Million Years Ago

  Researchers have discovered a new dinosaur species — a 'shark-toothed' theropod named Ulughbegsaurus — that is thought to have been the largest carnivorous predator of the time 90 million years ago.
