The Earth's Mantle and Earth's crust are in a fierce battle for death … the super-continent

The hot, sticky center of the earth and its cold, hard outer shell are both responsible for the creeping (and sometimes catastrophic) movement of tectonic plates. But now new research shows a fascinating balance of power – the dripping mantle creates supercontinents while the crust tears them apart. To arrive at this conclusion about the process of plate tectonics the …

Comets and interstellar objects could export Earth's life to the Milky Way

For over a century, proponents of panspermia have argued that comets, asteroids, spaceborne dust, and planetoids are spreading life in our galaxy. However, in recent years, scientists have argued that this type of distribution can go beyond star systems and be intergalactic. Some have even proposed fascinating new mechanisms for how this distribution could take place. For example, it is …

This is Earth's closest planetary solar system

Eerie and Wonderful Planets Beyond Our Solar System This is an artistic depiction of a Neptune-type exoplanet in the icy exteriors of its star system. It could look like a big, newly discovered gas giant that takes about 20 years to orbit around a star 11 light-years away from Earth. Eerie and Wonderful Planets Beyond Our Solar System This image …

NASA launches long-delay ICON space weather satellites to study the Earth's ionosphere

CAPE CANAVERAL, Fla. – A long-awaited NASA mission to study the upper Earth's atmosphere has finally started after years of delays. The spaceship Ionospheric Connection Explorer (ICON) was launched this evening (October 10) at 22:00. EDT (0200 GMT on 11 October) aboard a Northrop Grumman Pegasus XL rocket fired in the air from its carrier aircraft, a Stargazer L-1011. The …

Earth's gravitational wave detection network has a new observatory

The world's most powerful tool for detecting space-time waves is greatly improved. An observatory in Japan joins three giant detectors in Washington, Louisiana and Italy to form a global network of powerful observatories that study waves in space-time. The network will expand an area of ​​science born only four years ago when the Laser Interferometer Gravitational Wave Observatory (LIGO) solved …

Is the theory about the Earth's climate wrong in the last 15 million years?

Left: Large coccoliths – slices of calcium carbonate, which prepare single-celled algae, so-called coccolithophores – from the Middle Miocene around 16 million to 11.6 million years ago. Right: Small Coccoliths from the Pleistocene about 2.6 million to 11,700 years ago. Picture credits: Weimin Si A key theory that attributes Earth's climate evolution to the degradation of Himalayan rocks could not …

There is some bad news from Earth's last major heatwave

Fifty million years ago, at the beginning of the Eocene, the world was much warmer than it is today. This time is considered the best guide to the conditions that humanity can expect if we do not take action to reduce greenhouse gas emissions. The most advanced model of the early Eocene atmosphere to date warns of extreme warming, which …

A distant asteroid collision gave Earth's biodiversity an age-old thrust

About 466 million years ago, there was an asteroid collision in the asteroid belt between Mars and Jupiter. The collision caused the breakup of a large asteroid and created a dust shower throughout the entire solar system. This event is called Ordovician Meteor Event and its dust caused an ice age here on Earth. This ice age contributed to a …
