Astronomical calendar 2018

We review, month by month, all the astronomical events that we can enjoy in this 2018: rains of stars, eclipses, superlunas...


2018  is a year with great activity for amateurs and professionals in astronomy. During the next twelve months we will enjoy the beautiful rains of stars, superlunas, eclipses… So that you do not miss even one of the astronomical events of this year, here is our astronomical calendar 2018.

This astronomical calendar of celestial events contains dates for remarkable celestial events. Most of the astronomical events in this calendar can be seen with the naked eye, although some may require a good pair of binoculars for better viewing.

Regarding the events that we consider to be the most prominent in this 2018 we could highlight oppositions of  outer planets, elongations of the inner planets, eclipses of Sun and Moon, the closest conjunction of two planets to the naked eye by 2018, the best concealment easily visible of a bright star and a planet by 2018, comets programmed to reach perihelion this year, meteor showers, especially the Lyrids (April 22), the Ariétidas (June 7), the Perseids (August 12), the Draconians (October 8), the Orionids (October 10), the Biélidas (December 3) and the Geminids (December 14).

The year has already begun with a good astronomical footing, offering a full moon in the month of January from January 1 to January 2, the first of two full moons this month. The second one is called Blue Moon.

So you do not miss out, calendar events are organized by dates and times in Coordinated Universal Time (UTC), which we must convert to our corresponding local time. For Spain, it is UTC + 1.

After the  supermoon in early January, in which the Moon was at its closest point to Earth and could be seen a little larger and brighter than normal, at the end of the month, on January 31, we expect a total eclipse of the moon, although we will not be able to see it from Spain. Yes west of North America, across the Pacific, to Asia and Australia. During the eclipse, the Moon will gradually darken and then acquire a rusty red or blood red color. The 31st is also a blue moon day, as it is the second full moon of the same month.


On February 15 we have a new one. This phase occurs at 21:05 UTC. It is the best time of the month to observe weak objects such as galaxies and star clusters because there is no moonlight to interfere. We will also have a partial solar eclipse. A partial solar eclipse occurs when the Moon covers only a part of the Sun, as if we were chewing a cookie. We remind that this type of eclipses can only be observed safely with a special solar filter or looking at the reflection of the Sun. This partial eclipse will only be visible in parts of Chile, Argentina and Antarctica.
