Later this month—June 23, to be precise—the public will at last get its first glimpse of science images from the Vera C. Rubin Observatory, one of the most exciting and transformative telescopes to come online in generations.
Named for the eponymous astronomer who pioneered early studies of dark matter, the Rubin Observatory will significantly advance studies of this mysterious, invisible material which seems to be the gravitational glue holding galaxies together. But Rubin will do much, much more—so much, in fact, that it's almost impossible to properly summarize here. Or, for that matter, in our top story this week, which previews Rubin's awesome power.
The gist, however, is that the combination of Rubin's 8.4-meter starlight-gathering mirror and the largest-ever digital camera for astronomy will allow the observatory to survey the entire overhead sky every three nights, capturing huge numbers of transient astrophysical events that would slip through the cracks for most any other facility.
The result will effectively be the largest, most richly detailed high-definition view of the heavens humanity has ever seen, and astronomers are eager to mine it for untold scientific riches. They're also a bit nervous, as drinking from Rubin's 20-terabytes-per-night firehose of celestial data will be a challenge all its own. Another worry is the increasing numbers of conspicuously bright satellites perennially swooping overhead, each one potentially contaminating or otherwise interfering with Rubin's studies.
The observatory is set to discovery oodles of near-Earth asteroids and comets (maybe even a planet or two), and further afield is expected to find astronomical numbers of supernovae and galaxies. But Rubin's most promising projected contribution is simply "the unknown," in that its unique capabilities will probe the sky in entirely new ways likely to uncover all sorts of unanticipated phenomena. No one has ever been able to view the heavens like this before—and so no one knows exactly what to expect. But, chances are, whatever Rubin turns up will be enlightening, to say the least.
