Hubble to Use Moon as Mirror to See Venus Transit

  This mottled landscape showing the impact crater Tycho is among the most violent-looking places on our moon. Astronomers didn’t aim NASA’s Hubble Space Telescope to study Tycho, however. The image was taken in preparation to observe the transit of Venus across the sun’s face on June 5-6.   This mottled landscape showing the impact [continue reading]

A magnetic surprise for Venus Express

Venus is a rarity among planets – a world that does not internally generate a magnetic field. Despite the absence of a large protective magnetosphere, the near-Venus environment does exhibit a number of similarities with planets such as Earth. The latest, surprising, example is the evidence for magnetic reconnection in Venus’ induced magnetotail. Solar wind [continue reading]

But not just that: the second planet from the Sun turns on its axis so slowly that, for any survivor, a Venusian day would seem [continue reading]

Could Venus be shifting gear?

ESA’s Venus Express spacecraft has discovered that our cloud-covered neighbour spins a little slower than previously measured. Peering through the dense atmosphere in the infrared, the orbiter found surface features were not quite where they should be. Using the VIRTIS instrument at infrared wavelengths to penetrate the thick cloud cover, scientists studied surface features and [continue reading]
