Nature journal has published a series of articles devoted to the new discoveries by the European Space Agency’s (ESA) Venus Express space probe made on our neighbouring planet.

Using a new twist on standard Global Positioning System (GPS) technology, a team of scientists has found that Earth’s largest salt flat is rougher than expected, according to a new report led by Adrian Borsa of Scripps Institution of Oceanography at UC San Diego and published in Geophysical Journal International.

For more than a decade geoscientists have detected what amount to ultra-slow-motion earthquakes under Western Washington and British Columbia on a regular basis, about every 14 months.

As Rosetta closed in on Earth, swung by and then left on its course again, several instruments on the spacecraft were busy taking snaps. As it swung away, the OSIRIS camera also caught glimpses of the Moon.

Scientists and government representatives are poised to set up a global panel to deal with Earth's biodiversity crisis.

This striking composite of Earth by night shows the illuminated crescent over Antarctica and cities of the northern hemisphere. The images were acquired with the OSIRIS Wide Angle Camera (WAC) during Rosetta’s second Earth swing-by on 13 November.

Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet’s atmosphere.

Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse.

The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA’s Envisat satellite, this year’s ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes.

In scientific research, there is great satisfaction when theoretical work is eventually supported by experimentation. Such was the case this week for a team of Italian and US scientists when they received preliminary confirmation of a 10-year-old theory from a fluid science experiment that is currently orbiting the Earth on the Foton-M3 spacecraft.

Researchers have located the spin transition zone of iron in Earth’s lower mantle, a discovery which has profound geophysical implications.

In the first experiments able to mimic the crushing, searing conditions found in Earth’s lower mantle, and simultaneously probe tell-tale properties of iron, scientists have discovered that material there behaves very differently than predicted by models.
