Cosmic Calendar for 2017 / 2018
While we are preparing for the total solar eclipse in North America on August 21, 2017, there are plenty of other astronomical events to look forward to.
Coming up in 2018
A Supermoon looks around 12 to 14% larger than its counterpart, the Micromoon.
At 05:34 UTC on January 3, 2018, Earth will be at perihelion: the closest point to the Sun in its yearly orbit.
The opposite happens in July when Earth reaches aphelion.
The first major meteor shower of 2018, the Quadrantids, will peak on the night of January 3 and early morning hours of January 4.
The 2nd Full Moon in January is a Blue Moon. This is because it is the 2nd Full Moon in the same month.
The other definition of a Blue Moon is the 3rd Full Moon in an astronomical season with 4 Full Moons.
There is no New Moon in February 2018 making it a Black Moon. However, this is not the only definition of a Black Moon.
The Lyrid meteor shower is expected to peak between April 22 and 23. A First Quarter Moon may make viewing conditions difficult.
The best time to see shooting stars from the Eta Aquarid meteor shower is in the early morning, just before dawn, on May 6.
This solstice is the summer solstice in the Northern Hemisphere, where it is the longest day of the year.
In the Southern Hemisphere, it's the winter solstice and the shortest day of the year.
At 16:46 UTC on July 6, 2018, Earth will be at aphelion: the furthest point from the Sun in its yearly orbit.
The opposite happens in January when Earth reaches perihelion.
