Crikey, Mercury Is Going to Transit the Sun

Crikey, Mercury Is Going to Transit the Sun

Mercury's transit only happens about 13 times a century.

People in Greece will be able to witness a rare celestial show on Monday as Mercury passes between the sun and Earth, a phenomenon that is not expected to occur again until 2032. The orbits of the major planets exhibit slight tilts relative to the ecliptic; all are in the 1 to 2 degree range except for Venus at 4 degrees and Mercury at 7 degrees. When exoplanets transit their parent star, we can detect the dip in the star's brightness using space telescopes. Considering how rare these events really are, it's clear that our galaxy is teeming with planets. Instead, it's best to use a telescope with a solar filter, through which the transit will look like a small black speck passing in front of the Sun, which will appear 194 times larger than the speck. However, he warned that looking at the Sun without appropriate protection can seriously damage the eyes.

In fact, the only places it can't be seen from are Australia and most of Asia and Alaska, according to NASA's Jet Propulsion Laboratory.

The transit of Mercury on November 11, 2019, begins at 4:35 a.m. PST (7:35 a.m. EST), but it won't be visible to West Coast viewers until after sunrise. Disposable eclipse glasses should never be used with binoculars and telescopes; magnifying lenses increase sunlight's destructive power and can melt eclipse glasses' flimsy filters, as demonstrated in a video shared to YouTube in 2017 by journalist and photographer Vince Patton. This year, part of the 5.5-hour transit will be visible to much of North America starting at 12:36 p.m. UTC. See the transit map below to learn when and where the transit will be visible.

Mercury's trek across the Sun begins at 4:35 a.m. PST (7:35 a.m. EST), meaning viewers on the East Coast of the US can experience the entire event, as the Sun will have already risen before the transit begins. Mercury will be at its closest point to the Sun at approximately 9:20AM CST / 10:20AM EST, according to NASA.

"Viewing transits and eclipses provide opportunities to engage the public, to encourage one and all to experience the wonders of the universe and to appreciate how precisely science and mathematics can predict celestial events", Mitzi Adams, a solar scientist at Nasa, said in blog post on Friday.
