Recently Australian researchers found the first ever evidence of a plutonium radioactive isotope in the Earth's crust that originally came from outer space, namely a supernova.
Direct observations for the first time confirmed the long-standing predictions: radiative forcings of Earth are increasing due to human actions, affecting the planet’s energy balance and ultimately causing climate change.
If to cut the planet in half at the 60 degree longitude line, the half of the planet that consists mainly of the Pacific Ocean allowed much more heat to escape than the hemisphere that includes Africa, Europe and Asia.
European Space Station observatory has recorded five blue flashes from the top of a storm cloud, one of which ended with a blue jet streaking high into the stratosphere. Our understanding of these blue jet lightnings is limited.
The mass of human-made products at the start of the 20th ct was about 3% of the Earth’s biomass. However, due to increased urbanization and consumption, human-produced weight now outweighs the overall global biomass.
Sentinel-6 satellite lifted off on a SpaceX Falcon 9 rocket on Nov 21. Its mission now is to measure and chart the rise of the sea level more precisely than ever before.
Recent findings suggest that relatively close supernovas could theoretically have triggered at least four disruptions to Earth's climate over the last 40,000 years. What happens in space may not always stay in space.
When the asteroid struck our planet some 66 mil years ago, it created a 180-km impact crater and produced a gigantic magma chamber. A new research found that this hydrothermal system supported an entire microbial ecosystem.
Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth.
