  Humanity has landed a rover on Mars. Now, say scientists, it’s time to land a boat on Titan. This outlandish scenario could become reality, according to engineers presenting their proposals today (27 September 2012) at the European Planetary Science Congress.  Paddle concept for TALISE probe. This rendering of the proposed TALISE probe shows one possible [continue reading]

The Sun's Shockwaves Formed the Planets at Different Times

The Sun’s Shockwaves Formed the Planets at Different Times

  The early years of our Solar System were a turbulent time, and questions remain about its development. Dr Tagir Abdylmyanov, Associate Professor from Kazan State Power Engineering University, has been researching shockwaves emitted from our very young Sun, and has discovered that these would have caused the planets in our Solar System to form [continue reading]

Are Super-Earths Habitable?

Are Super-Earths Habitable?

  Exoplanet hunters estimate that there could be billions of super-Earths – planets with a mass of up to ten times that of Earth – orbiting stars in the Milky Way alone. But do super-Earths really deserve their name and would they be capable of hosting life? A study of the thermal evolution of rocky [continue reading]

Asteroid Oljato's Mysterious Magnetic Disturbance

Asteroid Oljato’s Mysterious Magnetic Disturbance

  Back in the 1980s, the arrival of asteroid 2201 Oljato inside the orbit of Venus heralded a flurry of magnetic activity. Now, results from ESA’s Venus Express spacecraft suggest that Oljato has lost its magnetic mojo. Dr Christopher Russell has presented an explanation for Oljato’s strange behaviour at the European Planetary Science Congress in [continue reading]

Does Jupiter's Moon Europa Have a Subsurface Ocean?

Does Jupiter’s Moon Europa Have a Subsurface Ocean?

  Europa, the enigmatic moon of Jupiter, is believed to be home to a subsurface ocean of liquid water. However, future missions to explore Europa’s ocean may need to dig deep. Research suggests that water does not stay in a liquid state near Europa’s surface for longer than a few tens of thousands of years [continue reading]
