Venus is seen next to the crescent moon during the daytime, prior to the start of occultation, on 7 December 2015 in Washington, D.C. in the United States. The moon occulted, or passed in front of, Venus for the second time this year.
The European Space Agency’s Venus Express spacecraft has found the best evidence yet for active volcanism on Earth’s neighbour planet. Seeing the planet’s surface is extremely difficult due to its thick atmosphere, but radar observations by previous missions to Venus have revealed it as a world covered in volcanoes and ancient lava flows.
On Thursday, 22 March observers in the British Isles with clear skies can see the 5½-day-old setting crescent Moon pass in front of first-magnitude star Aldebaran in the constellation of Taurus soon after 11:30pm GMT. Depending on where you live in the UK, you might just see the star reappear again shortly before the pair set.
