This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere. Some of these storms, including the Great Red Spot at upper left, have been churning in the planet’s atmosphere for many years, but when Juno obtained this view of Jupiter, the smaller, oval-shaped feature at the centre of the image was brand new.

Thunderstorm asthma, the unexpected impact of lightning storms on pollen allergies

Thunderstorm asthma, the unexpected impact of lightning storms on pollen allergies Source: Geolog ( European Geosciences Union ) Image credit: Michiel Baatsen, (distributed via imaggeo ) In October 2015 a series of massive thunderstorms rolled across the Eastern Mediterranean. In the hours and days that followed many people living along the Israeli coast had to go to their nearest medical centre because they were experiencing respiratory problems, which appeared very similar to asthma. But what could have caused these breathing problems? Read more.

Moon Craters a Window to Earth's Past

Moon Craters a Window to Earth's Past Story by Lonnie Shekhtman (Source: NASA Visualization Explorer) By looking at the Moon a group of scientists is challenging our understanding of a part of Earth’s history. On Earth, asteroid impacts increased by two to three times starting around 290 million years ago. For decades many experts assumed that early Earth craters have been worn away by the wind, storms, and other geologic processes. This idea explained why Earth has fewer older craters than expected compared to other bodies in the solar system, but it made it difficult to find an accurate impact rate and to determine whether it had changed over time. But by studying data on Moon craters from NASA’s Lunar Reconnaissance Orbiter, scientists found the Moon and Earth have historically shared a similar rate of asteroid impacts. The surface of the Moon is riddled with both ancient craters mostly undisturbed by erosion and craters from modern-day impacts making it the most complete and ac...

Greenland on the move

Greenland on the move Source: NASA Visualization Explorer 100 million years ago, Greenland was on the move. On its tectonic plate, it travelled from a more southern location northward to its current Arctic position, and along the way passed over a mantle plume or hotspot that left a record of its journey in Greenland's rocks.
