Here is a summary of the best celestial spectacles of next year for you to mark on your calendar and prepare your observation instruments. Check out some of the main astronomical events of 2025!

Astronomical Calendar 2025

Quadrantid meteor showers – January 3 and 4 In the early days of the year, on the night and morning of January 3 and 4, respectively, the Quadrantid meteor shower will peak in activity, a medium-sized event capable of producing around 40 meteors per hour.

The shower is produced by the debris of an extinct comet called 2003 EH1 and occurs every year from January 1 to 5.

Total Lunar Eclipse – March 14

In March, the sky will be adorned by the famous "Blood Moon". The phenomenon is, in fact, a total lunar eclipse, in which the Earth will block the sunlight that reaches the Moon, causing the satellite to acquire a reddish hue due to the refraction of light in the Earth's atmosphere.

Partial Solar Eclipse – March 29

A partial solar eclipse occurs when the Moon covers only a portion of the Sun, sometimes resembling a bite of a cookie. A partial solar eclipse can only be safely observed with a special solar filter or by looking at the Sun’s reflection.

This partial eclipse will be visible from all of Greenland and most of northern Europe and Russia. It will be best seen from Canada, where the Moon will cover about 93% of the Sun’s disk.

Perseid Meteor Shower – August 12 and 13 This famous meteor shower, caused by debris from Comet Swift-Tuttle, lights up the sky with fast, bright meteors. Although its peak is most intense in the Northern Hemisphere.

Saturn at Opposition – August 23

The ringed planet will be at its closest approach to Earth and its face will be fully illuminated by the Sun. It will be brighter than at any other time of the year and will be visible all night.

This is the best time to view and photograph Saturn and its moons. A medium to large telescope will allow you to see Saturn’s rings and some of its brightest moons.

Orionid Meteor Shower – October 21 and 22 The Orionids, produced by the space debris left behind by Halley’s Comet, will be visible in dark skies around the world. Although the meteor shower rate is moderate (about 20 per hour), the beauty of their long and bright trajectories makes up for any patient wait!

Geminid Meteor Shower – December 13 and 14

Closing out the year, the Geminid meteor shower promises to be one of the most intense events of 2025, producing up to 120 meteors per hour on peak nights.

Produced by debris left behind by an asteroid known as 3200 Phaethon, the vibrant colors and slow trajectories of its meteors are some of its striking features, making this shower a must-see for enthusiasts.

Supermoons In 2025, unfortunately, we won't have many supermoons, but below are the dates so you don't miss these celestial spectacles.
