ESA Science & Technology: Cluster discovers steady leak in Earth's plasmasphere

ESA Science & Technology: Cluster discovers steady leak in Earth's plasmasphere | Biosciencia News | Scoop.it
A steady wind, discovered by ESA's Cluster mission, is slowly escaping from Earth's plasmasphere - the torus of plasma that surrounds our planet's atmosphere. The outflow amounts to almost 90 tonnes a day.
Biosciencia's insight:

The environment that surrounds Earth, beyond the outermost layers of the atmosphere, is strongly shaped by the magnetic field of our planet. There, space is filled with electrons and positive ions, which move along the magnetic field lines. The interaction between Earth's magnetic field and the solar wind produces the complex topography of the magnetosphere.

Earth and Moon Got Water from Common Source

Earth and Moon Got Water from Common Source | Biosciencia News | Scoop.it
Measurements of the chemical composition of Moon rocks suggest that Earth was born with its water already present, rather than having the precious liquid delivered several hundred million years later by comets or asteroids.
Biosciencia's insight:

Analyses of rocks brought back by the Apollo program show that the Moon's water shares a common origin with water on Earth.

Global cooling as significant as global warming, research shows

Global cooling as significant as global warming, research shows | Biosciencia News | Scoop.it
A "cold snap" 116 million years ago triggered a similar marine ecosystem crisis to those witnessed in the past as a result of global warming, according to research published today in Nature Geoscience.
Biosciencia's insight:

The international study involving experts from the universities of Newcastle, UK, Cologne, Frankfurt and GEOMAR-Kiel, confirms the link between global cooling and a crash in the marine ecosystem during the mid-Cretaceous greenhouse period.

Earth as Art

Earth as Art | Biosciencia News | Scoop.it

During a span of 40 years, since 1972, the Landsat series of Earth observation satellites has become a vital reference worldwide for understanding scientific issues related to land use and natural resources.

Beyond the scientific information they supply, some Landsat images are simply striking to look at, presenting spectacular views of mountains, valleys, and islands as well as forests, grasslands, and agricultural patterns. By selecting certain features and coloring them from a digital palate, the U.S. Geological Survey has created a series of "Earth as Art" perspectives that demonstrate an artistic resonance in satellite land imagery and provide a special avenue of insight about the geography of each scene.
