The sardonic proverb “nothing is certain but death and taxes,” can now be recast for the cosmos.
Last week’s announcement of the inevitable collision of the Andromeda galaxy with the Milky Way is one of only two apocalyptic astronomical predictions that we can be absolutely certain of. The other is the death of our sun. Purely deterministic processes drive both.
Another day, another adventure in space. Following not too far behind the Annular lunar eclipses, the transit of Venus has been another event for NASA’s Solar Dynamics Observatory to capture, and of course, time-lapse for our viewing pleasure. As this hypnotic footage shows, the astronomical phenomenon truly helps to understand the expanse of space in our solar system and as it turns out, helps scientists in their search for exoplanets.
