The comet Venus and its missing craters

Since the dawn of the Space Age, the planet Venus has been a proving ground for competing hypotheses in planetary science. From the 1950s to 1970s, Venus was at the center of a blazing scientific controversy. In 1950, in the bestselling book Worlds in Collision, the...

Martian dust storm now officially a global dust event

One of the most intense dust storms ever observed on Mars is raging across the planet since May 30, 2018. The storm grew rapidly over the next 20 days and is now officially a 'planet-encircling' (global) dust event. Although Martian dust storms are common...

Two Super-Earths around red dwarf K2-18

New research using data collected by the European Southern Observatory (ESO) has revealed that a little-known exoplanet called K2-18b could well be a scaled-up version of Earth. Just as exciting, the same researchers also discovered for the first time that the...

Unexpected atmospheric vortex behavior on Saturn’s moon Titan

A new study, led by a University of Bristol earth scientist, has shown that recently reported unexpected behavior on Titan, the largest moon of Saturn, is due to its unique atmospheric chemistry. Titan’s polar atmosphere recently experienced unexpected and...

Closest temperate world orbiting quiet star discovered

A temperate Earth-sized planet has been discovered only 11 light-years from the Solar System by a team using ESO’s unique planet-hunting HARPS instrument. The new world has the designation Ross 128 b and is now the second-closest temperate planet to be...

ALMA discovers cold dust around nearest star

The ALMA Observatory in Chile has detected dust around the closest star to the Solar System, Proxima Centauri. These new observations reveal the glow coming from cold dust in a region between one to four times as far from Proxima Centauri as the Earth is from the...

Saturn's radiation belts: A stranger to the solar wind

The high energy proton population in the environment of Saturn develops independently of the solar wind - and thus in a considerably different way from the one on Earth. The radiation belts of Earth and Saturn differ more strongly than previously assumed. In these...

Surprisingly erratic X-ray auroras discovered at Jupiter

ESA and NASA space telescopes have revealed that, unlike Earth’s polar lights, the intense auroras seen at Jupiter’s poles unexpectedly behave independently of one another. Auroras have been seen in many places, from planets and moons to stars, brown...

Large solar storm sparks global aurora and doubles radiation levels on Martian surface

When charged particles from a solar storm reached Mars this month, they set off an aurora 25 times brighter and surface level radiation readings twice as high as any previous measurements. An unexpectedly strong blast from the Sun hit Mars this month, observed by...

Saturn's 'weird' magnetic field perplexes scientists

The Cassini probe's first results from inside Saturn's rings make scientists question the conventional wisdom on how planets form magnetic fields. As NASA's Cassini spacecraft makes its unprecedented series of weekly dives between Saturn and its rings,...
