Godspeed to the Stars, Mr. Nimoy

Leonard Nimoy (1931-2015), who played Mr. Spock on Star Trek, has died, aged 83. He played a half-alien, always relying on cold logic, but saved by his capacity for human empathy and emotion. Nimoy's final tweet, telling his followers to 'Live Long and Prosper' (Hat tip: The Verge):

A life is like a garden. Perfect moments can be had, but not preserved, except in memory. LLAP

Caption for the above photograph: "Buffeted by the solar wind, Comet Lovejoy's crooked ion tail stretches over 3 degrees across this telescopic field of view, recorded on February 20. The starry background includes awesome bluish star Phi Persei below, and pretty planetary nebula M76 just above Lovejoy's long tail. Also known as the Little Dumbbell Nebula, after its brighter cousin M27 the Dumbbell Nebula, M76 is only a Full Moon's width away from the comet's greenish coma. Still shining in northern hemisphere skies, this Comet Lovejoy (C/2014 Q2) is outbound from the inner solar system some 10 light-minutes or 190 million kilometers from Earth. But the Little Dumbbell actually lies over 3 thousand light-years away. Now sweeping steadily north toward the constellation Cassiopeia Comet Lovejoy is fading more slowly than predicted and is still a good target for small telescopes."
