1 00:00:19,886 --> 00:00:26,159 the transit of Mercury welcome stargazers I'm James Albert director the 2 00:00:26,259 --> 00:00:30,163 kike Sola pop planetarium in Gainesville Florida and I'm Dean Regas astronomer 3 00:00:30,263 --> 00:00:33,900 for the Cincinnati Observatory we're here to help you find your way around 4 00:00:34,000 --> 00:00:40,040 the sky the astronomical event of 2016 it's happening next week and I have been 5 00:00:40,140 --> 00:00:44,944 waiting years to see it it's not a planetary conjunction and it's not a 6 00:00:45,045 --> 00:00:49,949 lunar or solar eclipse but it is something so rare that it only occurs 13 7 00:00:50,050 --> 00:00:55,188 times every century the tiny planet Mercury will go directly between us and 8 00:00:55,288 --> 00:00:59,526 the Sun will be able to see mercury completely silhouetted by the fusion 9 00:00:59,626 --> 00:01:05,031 furnace that is our son it's called the transit of Mercury and we'll get you 10 00:01:05,131 --> 00:01:11,171 ready to view this rare event safely on may ninth well lets show you the date is 11 00:01:11,271 --> 00:01:15,842 Monday May 9 and is just before sunrise if we're going to see mercury pass in 12 00:01:15,942 --> 00:01:20,113 front of the Sun that means we have to look during the daytime so we'll go 13 00:01:20,213 --> 00:01:22,348 through the entire day to see what happens 14 00:01:22,449 --> 00:01:27,353 first let's appreciate the sunrise not always like Dean over there really see 15 00:01:27,454 --> 00:01:30,256 the beauty and grandeur of the sky at this time of day 16 00:01:30,356 --> 00:01:35,762 definitely beautiful the sunrise North East move up and to the right 17 00:01:35,862 --> 00:01:39,466 cuts slowly and surely across the southern sky and then set in the 18 00:01:39,566 --> 00:01:41,134 northwest 19 00:01:41,234 --> 00:01:45,405 did you notice anything I sure didn't I thought this transit of Mercury was some 20 00:01:45,505 --> 00:01:48,441 awesome event I didn't see anything out of the ordinary 21 00:01:48,541 --> 00:01:52,812 that's because the transit of Mercury is a sub alignment that takes us skillful 22 00:01:52,912 --> 00:01:58,451 savvy observer to witness and one needs access to some extra equipment Maria 23 00:01:58,551 --> 00:02:02,689 small after all and staring at the Sun too long will strike you blind 24 00:02:02,789 --> 00:02:07,293 first safe solar filter one that is approved by astronomers to look at the 25 00:02:07,393 --> 00:02:14,334 Sun do not use sun glasses for CDs film negatives mylar X-rays or any homemade 26 00:02:14,434 --> 00:02:19,139 filter they will not protect solar eclipse glasses and number fourteen 27 00:02:19,239 --> 00:02:22,809 welder's glass would protect you from the Sun but you'll need more than that 28 00:02:22,909 --> 00:02:31,251 to see mercury on that day you'll need is so small compared to the Sun that you 29 00:02:31,351 --> 00:02:33,386 will not be able to see it with the naked eye 30 00:02:33,486 --> 00:02:37,924 that means you need to put say filters on binoculars and telescopes just to see 31 00:02:38,024 --> 00:02:39,526 it 32 00:02:39,626 --> 00:02:42,495 good filters go in front of the lenses or mirrors and block out the light 33 00:02:42,595 --> 00:02:47,033 before entering the telescope once you're properly outfitted tears of the 34 00:02:47,133 --> 00:02:53,173 Sun will look like with a zoomed in view your first see mercury 7:13 a.m. Eastern 35 00:02:53,273 --> 00:02:57,977 Daylight Time as a little black spot growing along the edge of the Sun at 36 00:02:58,077 --> 00:03:03,383 7:16 worker will appear completely inside the Sun's disk to paraphrase a 37 00:03:03,483 --> 00:03:09,923 certain song they'll be a little black spot on the sonne this may indeed then 38 00:03:10,023 --> 00:03:13,993 you can watch mercury slowly continue in its orbit around the Sun and passed 39 00:03:14,093 --> 00:03:19,232 directly in front of it minute by minute hour by hour at 10:30 a.m. it will be 40 00:03:19,332 --> 00:03:24,971 about halfway through then at 2:38 p.m. mercury starts heading off the Sun and 41 00:03:25,071 --> 00:03:26,606 three minutes later 42 00:03:26,706 --> 00:03:31,010 mercury is invisible once more so a transit of Mercury can last over seven 43 00:03:31,110 --> 00:03:35,615 hours with the most exciting parts at the beginning and the end 44 00:03:35,715 --> 00:03:39,786 if you don't have a safe solar filter and a telescope contact your local 45 00:03:39,886 --> 00:03:44,557 astronomy club or planetarium chances are they'll be doing this rare event and 46 00:03:44,657 --> 00:03:49,062 welcome guests astronomers whether amateur or professional love sharing the 47 00:03:49,162 --> 00:03:53,533 heavens with others so see if your community is planning a transit of 48 00:03:53,633 --> 00:03:58,471 Mercury party on May night finally noticed that the transit last from 7:13 49 00:03:58,571 --> 00:04:04,677 a.m. to 2:41 p.m. Eastern Daylight Time please adjust your time accordingly 50 00:04:04,777 --> 00:04:08,081 that means that people on the west coast will not see the beginning of the 51 00:04:08,181 --> 00:04:13,286 transit the Sun will not have risen at that time but they're not you'll still 52 00:04:13,386 --> 00:04:17,991 see hours of a performer creed two parts the Sun's disk stargazers on the east 53 00:04:18,091 --> 00:04:21,127 coast will see the entire thing including my brother Chris whose 54 00:04:21,227 --> 00:04:27,267 birthday is may not have waited to see this since November 8 2006 that was the 55 00:04:27,367 --> 00:04:32,238 last transit of Mercury and I got clouded out and if you miss this one 56 00:04:32,338 --> 00:04:36,909 the next transit of Mercury won't be until November 11th 2019 in other words 57 00:04:37,010 --> 00:04:41,010 I may not be better keep looking
