The nights before Christmas this year bring a discreet but very special astronomical spectacle: the Ursid meteor showerThis is the last major meteor event of the year and a good excuse to get out into the countryside, bundle up, and look up at the winter sky.
For those who live in the northern hemisphere, especially in Europe and SpainThe viewing conditions for the Ursids in 2025 will be particularly favorable, with an almost absent Moon and a moderate meteor rate that allows you to enjoy the sky calmly, without the need for telescopes or complicated equipment.
When will the Ursid meteor shower occur in 2025?
The activity of the The Ursids meteor shower extends approximately from December 17 to 26, 2025.And if you want to know the best dates and places To observe them, the key time for those who want to see the maximum number of meteors is between the night of December 21 and the early morning of December 22. It is during this interval that the Earth passes through the densest area of debris from the comet responsible for this shower.
Data from astronomical organizations and entities such as the American Meteor Society They point out that the Peak activity will occur in the hours before dawn on December 22ndAnd for practical information on how to observe meteor showers, you can consult best observation tipsDuring that stretch of the early morning, the point in the sky from which the meteors appear to originate (the radiant) will be high above the northern horizon, increasing the likelihood of sightings.
Spectacular figures are not expected in this rainfall: the usual figures are between 5 and 10 meteors per hour under ideal conditions. However, experts remind us that the Ursids are somewhat capricious and, in some years, they have been observed occasional peaks of up to 20-25 traces per hour, especially near the maximum.
Another factor that works in our favor in 2025 is the phase of the MoonDuring the peak of the rain, our satellite will present barely around 3% illuminationA very thin and dim moon that will hardly be a nuisance, meaning darker skies and better conditions for appreciating shooting stars.
Where to see it best: Northern Hemisphere, Spain and Europe
The Ursid meteor shower is a phenomenon typical of the northern hemisphereThe radiant is located in the constellation Ursa Minor, very close to the North Star (Polaris), a region of the sky that never sets below the horizon in mid and high northern latitudes.
This means that, in places like Spain, most of Europe and other areas of the northern hemisphereThe radiant remains above the horizon throughout the night, allowing observation to be attempted at virtually any time, although there will always be better times.
In mid-latitudes of Europe, the best time slot The best time to observe is usually between approximately 2:00 and 6:00 AM, when the Little Dipper is highest in the sky. During this window, the number of visible meteors tends to increase, especially if the sky is clear and light pollution is low.
In more southerly parts of the northern hemisphere, such as the eastern Mediterranean or regions near the equator, The radiant appears lower above the northern horizonThis reduces the visible rate somewhat, but does not completely prevent observation. However, from much of the Southern Hemisphere, the radiant is barely visible and the rain is practically unobservable.
Compared to other more spectacular meteor showers, such as the Geminids or the Perseids, the Ursids often go somewhat unnoticed. Even so, coinciding with the Christmas season and long, cold nights, For many fans, they have become a kind of "astronomical farewell" to the year., ideal for sharing with family or friends.
Origin of the Ursids: comet 8P/Tuttle
As with most meteor showers, the Ursids are linked to a parent body. In this case, it is the periodic comet 8P/Tuttle, discovered in the 19th century and which regularly returns to the environment of the inner Solar System leaving behind a trail of particles.
When the Earth crosses that trail of dust and small rock fragmentsPart of that material impacts the atmosphere at high speed. Upon contact with the air, the particles heat up and disintegrate, generating the brief flashes we commonly call flares. “shooting stars”but they are actually meteors.
Experts describe the Ursids as a shower of moderate speedThis means that many of its meteors leave relatively clear and sometimes somewhat longer trails in the sky. In certain years, other meteors have also been observed. bright meteors, and even small bursts of more intense activity during the peak.
The name of the rain comes from its apparent radiant, located in the constellation of the Little Bear (Ursa Minor)Although meteors can streak across the sky in virtually any direction, if you mentally extend the path of the luminous trails, they all seem to converge in that area near Polaris.
Tips for observing the Ursid meteor shower
One of the advantages of meteor showers is that Sophisticated equipment is not required.In fact, using binoculars or telescopes is more of a hindrance than a help, because They greatly limit the field of vision And meteors are very fast objects that cross wide areas of the sky.
To make the most of the night of December 21st to 22nd, it's a good idea to look for a A dark place, away from streetlights, houses, and bright screensThe less artificial light there is around, the more faint stars and meteors you'll be able to spot. Rural areas, sparsely populated beaches, or mountainous regions are usually good options.
It is advisable to arrive a little early to allow the Let your eyes adapt to the darkness for at least 20 or 30 minutesDuring this time, it's best to avoid looking directly at sources of intense white light. If you need to use a flashlight, ideally it should have red filter, as it interferes less with night vision.
It's also a good idea to prepare the observation with comfort in mind. Warm clothing, hat, gloves, blanket or sleeping bag And, if possible, a sun lounger or mat to lie on helps you stay outdoors longer without getting cold. Looking up for hours can be tiring for your neck, so lying down makes the experience much more comfortable.
As for where to look, you don't need to fix your gaze exactly on the Little Dipper. Meteors can appear in any region of the skySo the best thing to do is to cover as much of the sky as possible, orienting yourself roughly towards the north and northeast and letting your gaze move in a relaxed way across the entire field.
Apps, schedules, and location differences
Although the general peak rainfall times are similar across the Northern Hemisphere, the local time at which the Little Dipper reaches its highest point It varies slightly depending on the longitude and latitude of each observer. For further refinement, the following can be used astronomical applications such as Stellarium or other online tools.
These resources allow you to enter the exact location and see at what moment is the radiant highest above the horizonThis usually coincides with the final stretch of the night. However, it's not necessary to wait for the radiant's highest point to enjoy the phenomenon: as long as it's above the horizon, there's a chance of seeing meteors.
As specialized portals and observatories point out, Meteor showers are not a continuous spectacleIt's normal to spend a few minutes without seeing anything and then suddenly detect several traces in a short interval. That's why patience is almost as important as a coat.
In Europe, including Spain, the better chances of observation They are concentrated between 1:00 and 2:00 AM and dawn on the 22nd, weather permitting. Thick clouds or fog can ruin the experience, so it's advisable to check the weather forecast before planning a night out.
Those who decide to stay in the city may also see a shooting star, but Light pollution will greatly reduce the number of visible meteorsTherefore, even a small shift towards the outskirts can make a noticeable difference in the quality of the sky and the number of flares observed.
Combining Long nights, very faint moon, and a slow pace of meteors This makes the 2025 Ursid meteor shower an interesting opportunity for those who want to get started in stargazing. Without large crowds or excessive expectations, this shower invites you to take your time, look north, and let the shooting stars appear little by little.
