Draining Earth’s oceans – amazing animation by the JAXA scientist

The Japanese Space Agency (JAXA) and former NASA Goddard Planetary scientist Dr. James O’Donoghue (@physicsJ) created another amazing video. He showed that what if we slowly drain the Earth’s oceans and see the two-thirds of Earth’s surface (that is currently under the oceans) we don’t get to see. In other words, how our planet would …

Investigating Overpopulation: The Solutions

Urbanization is just one of the many effects of overpopulation here on Earth, along with the rapid dwindling of the natural environment as a whole. The general consensus across the scientific community is that a number of factors have contributed to global overpopulation. More than 7.7 billion people live on Earth as of 2020, largely …

The oldest material on Earth has been found in a meteorite and it is way older than the Solar System!

Scientists have found the oldest material on Earth in a 7 billion-year-old meteorite – a space rock that is way older than the Earth and even older than our solar system! For comparison, the age of Earth is approximately 4.54 billion years, with an error range of about 50 million years. The Sun is about …

Scale and composition of Earth’s surface

In collaboration with Dr. Christine Houser (@seismodoc), a specially appointed assistant Professor of solid Earth geophysics at the Earth-Life Science Institute in Japan, NASA Goddard Planetary Scientist Dr. James O’Donoghue (@physicsJ) created another amazing animation titled “Scale and Composition of Earth’s surface: Major constituents of the crust, water, and atmosphere” and published on his YouTube …

Earth’s atmosphere is leaking and NASA is sending rockets to understand how

Earth’s atmosphere is leaking: around 90 tonnes of material escapes and streams out into space from our planet’s upper atmosphere every single day. To understand this escape, NASA launches rockets into space. The space agency also sends scientists to a tiny Arctic town named Ny-Ålesund (English: New Alesund) on the island of Spitsbergen in Svalbard, …

Forget the Anthropocene: we’ve entered the synthetic age

One fact about our time is becoming increasingly well-known. No matter how far you travel, no matter in which direction you point, there is nowhere on Earth that remains free from the traces of human activity. The chemical and biological signatures of our species are everywhere. Transported around the globe by fierce atmospheric winds, relentless …
