Get ready to mark it in your calendars, a total solar eclipse is happening next month - in under two weeks to be exact.
In the run up to the event, scientists are giving out information for the best viewing experience possible - As well as informing people on how to stay safe.
Experts have organised maps outlining the 'path of totality' where the moon's shadow will cross.

The period of totality will be when the sun is 100% concealed behind the moon, an unusual event where we can look directly at the sun, observing its glowing corona around the edges of the moon.
According to Michael Zeiler, a geographer and co-founder of Great American Eclipse, a resource for solar eclipses around the world, eclipse calculators determine whether your location will fall within the moon's shadow.
Even if it doesn't, these tools like calculators can provide insight into how much of the sun will be hidden from your viewpoint.

Everywhere else in the U.S. as well as places like the UK, Spain and Iceland will observe a partial eclipse, which means only some portion of the sun will be exposed.
The online Time and Date calculator shows a table of the countries that will have the best view of the eclipse, along with other handy facts.
For instance, Canada is shown to be the place to watch the event, with the total eclipse starting at 10.40 (PDT) and expected to last 34 minutes and four seconds.
Mexico follows closely behind on the viewing table with totality expected at 09:32 (PDT), lasting for 40m, 43 seconds and the United States viewing will be at 06:27 (HST), lasting for 1h, 7m and 58 seconds.

For those of us in the UK will see a partial eclipse at 19:52 (BST).
According to other data on the website, 8.19% of the world's population will witness any part of the eclipse - that's around 652 million people. Moreover, only 0.55% or 43 million people will see the event in its totality.
Zeiler said: 'For the people who are in the partial eclipse that can't get to the total solar eclipse, they can still see some interesting things.
'One of the most interesting things they can see is the shadow projections from tree leaves because the gaps between leaves in a tree can form these shadows on the ground that are very striking.'
