How calm to watch Mercury pass before the Sun today



As Mercury orbits the sun every 88 days, an inclined orbit means that it only crosses between Earth and the sun about 13 times in a century. This time, transit will be visible in many regions (including Europe and Africa), but people from the Americas will have the best view.

However, if you plan to check it out, you'll have to be careful. If Mercury could speak (and astrologically, it is the planet of communication), she would say "don't look directly at me while crossing the sun." This will damage your eyesight, and anyway you won't be able to see Mercury with the naked eye, even with dimming goggles ̵

1; that's too small.

Rather, you will need a telescope or binoculars fitted with a special solar filter. If you don't have one, "your local astronomy club may be able to see the transit using specialized, properly filtered solar telescopes," NASA notes. You can't use a regular telescope or binoculars, even in conjunction with sunglasses for dimming, the space agency added.

If physical watching is not in question, the best bet will be to go online. The NASA Solar Dynamics Observatory (SDO) satellite will have the best possible view of the eclipse, and NASA will broadcast near-real-time transit views right here. To give you an idea of ​​what you will see, you can check out the 2016 transit captured by SDO above.
