See asteroid 2018 CB’s close encounter on 9 February

As darkness falls over Western Europe on the evening of 9 February, near-Earth asteroid 2018 CB lies almost overhead as seen from the UK. We show you how and when to find this 30-metre-wide space rock as it speeds through the constellations of Perseus and Triangulum, passing just one-fifth of the Moon’s distance away at 22:27 UT (10:27pm GMT).


See bright near-Earth asteroid 2002 AJ129 dash through Virgo and Leo, 5–7 February

Possibly a kilometre or more in size, Apollo asteroid 2002 AJ129 passes just 10.9 lunar distances from Earth at 21:30 UT (9:30pm GMT) on 4 February — its closest approach for 114 years. For a few nights around this date the magnitude +12.6 body is well placed for observers as it gallops through the constellations of Virgo and Leo into Cancer at a rate of up to 40 degrees/day. We show you where and when to look for it.

Curiosity Mars rover snaps a selfie

The Curiosity Mars rover used a camera on the end of its robot arm to take a selfie on the slopes of Mount Sharp before moving on to begin exploring nearby clay-rich soils. The rover is slowly working its way up the lower slopes of the mountain, looking for changes that might indicate the transition from warmer, wetter eras to the dry, frigid environment seen today.
