Eclipses are one of the astronomical phenomena that generate the most expectation among fans of observing the sky. Each year has between 4 and 7 eclipses, although the most common is that there are 4. This is precisely what will happen in 2025: we will be able to enjoy two solar eclipses and two lunar eclipses. We will not always be able to see them from where we are, so anticipating them, to be able to get closer to the area from where they can be enjoyed, or simply to follow them live from a distance, will be the best way not to miss them or to enjoy them and feel their magic when they occur.

Contrary to what many think, eclipses are not isolated events. They always occur in pairs. When there is an eclipse, whether solar or lunar, there will be another of a different type about two weeks later. That is to say, A solar eclipse will be followed by a lunar eclipse and vice versa.. This phenomenon means that, every time two eclipses come, it is said that one is approaching «eclipse season«, coinciding each season with the full moon and new moon phases of one or two months in the lunar calendar.

We explain to you When is there a solar eclipse or lunar eclipse in 2025, what type of eclipse each will be and where they can be seen from. In addition, here you will find information about what an eclipse is and what types of eclipses there are, as well as curiosities such as what are the “blood moons” that occur in total lunar eclipses or how eclipses affect us.

When is there an eclipse in 2025?

In 2025 we will see four eclipses, two in March and two in September:

Total lunar eclipse on March 14, 2025

The first eclipse of 2025 will be a total lunar eclipse. Lunar eclipses can only occur during the Full Moon phase. At this time, the Moon is in the opposite position to the Sun with respect to the Earth, creating the perfect conditions for the eclipse to occur.

• What will the eclipse be like: The Moon will completely enter the Earth’s shadow and become dark. It is expected that on this occasion the moon will acquire a reddish color, a phenomenon known as “Blood Moon” and which we explain in depth below.
• From where you can see: According to the reference website Time and Date, this eclipse will be visible (at least some phases) in Europe, much of Asia, much of Australia, much of Africa, North America, South America, Pacific, Atlantic, Arctic, Antarctica. In Spain, it will occur close to dawn, so only the initial part will be seen of the eclipse. Only in the west of the peninsula can some of its total phase be seen, but in the rest of the country only part of its partial and penumbral phase can be seen: during its total phase, the Moon will still be below the horizon at that time.

Unlike what happens with solar eclipses, To see those of Luna, no special equipment is required.. To enjoy it well, look for a dark place without light pollution and raise your gaze to the sky.

Partial solar eclipse on March 29, 2025

The second eclipse of 2025 will be a partial solar eclipse that can be enjoyed from many parts of the world. Remember that you should never look directly at a solar eclipse because you can damage your eyes. You must protect your eyesight with appropriate and approved glasses.

• What will the eclipse be like: In a partial solar eclipse, as in this case, only part of the Sun is covered by the Moon. The solar surface then appears with a «bite», greater or less as you approach the strip of maximum visibility of the eclipse.
• From where you can see: This eclipse can be seen, at least in part, from Europe, northern Asia, northern/western Africa and much of North America. However, the best places to see it due to its spectacular nature will be northeastern Canada and Greenland (between 80% and 90% solar occultation). From Iceland the occultation of the Sun will also be very marked (around 65-70%). In Spain it can be seen well, although with a smaller magnitude: It will begin at approximately 9:50 in the morning and the maximum point will be at 11:40 (local time), in which the occultation of the sun will be between 30% (Galicia) and 10% (Palma), depending on the area.

Total lunar eclipse on September 7, 2025

The third eclipse of 2025 is another total lunar eclipse. Unlike solar eclipses, which are only seen in a certain strip of the planet, lunar eclipses can be seen in all parts of the Earth where it is night. That is why they can usually be enjoyed in many more places.

• What will the eclipse be like: The Moon, in its orbit around the Earth, will completely enter the Earth’s umbra and its obscuration will be evident.
• From where you can see: The parts of the world from which it will be seen (at least in part) are Europe, Asia, Australia, Africa, Western North America, Eastern South America, Pacific, Atlantic, Indian Ocean, Arctic, Antarctica. This time, almost all of Asia, the east coast of Africa and much of Australia will be able to enjoy the totality phase from start to finish. In Spain, the eclipse begins in the afternoon, when the Moon is still below the horizon (around 5:28 p.m. local time), so the first phases will not be visible. He maximum pointwhich will be at approximately 8:46 p.m.the Moon will already be rising over the horizon, so to enjoy it you will have to look for a place from which we have visibility to the east. What will be clearly visible, at night, will be the final partial and penumbral phases of the eclipse.

Partial solar eclipse on September 21, 2025

The fourth and last eclipse of the year will be a partial eclipse of the Sun which, unfortunately, will be visible from very few inhabited areas of our planet. Only about 400,000 people live in the area where the eclipse can be seen at its maximum magnitude.

• What will the eclipse be like: The moon will hide a part of the sun, which will show a bite in its surface, up to 70% at the moment of maximum magnitude.
• From where you can see: The areas from which it can be seen (at least in part) are South Australia, the Pacific, the Atlantic, and Antarctica. The most privileged area will be, specifically, New Zealand. From Spain, this partial solar eclipse will not be visible.

What is a lunar eclipse and why does it occur?

The lunar eclipses are fascinating astronomical events that occur as a result of the interaction between the Earth, the Moon and the Sun. A lunar eclipse occurs when The Earth is positioned directly between the Sun and the Moon. This alignment prevents sunlight from directly reaching the lunar surface, resulting in a complete or partial obscuration of the Moon.

It is important to understand that the Moon does not generate its own lightand that all the light we see reflected in it comes from the Sun. Therefore, when the Earth blocks the passage of sunlight, the affected areas of the Moon are plunged into darkness.

The lunar eclipse occurs when the Moon, in its orbit around the Earth, passes through the central part of the «umbra», the darkest shadow that our planet casts in space. What we observe during a lunar eclipse is, in essence, the shadow of our own planet projected on the lunar surface.

Types of lunar eclipses

Lunar eclipses are classified into different categories based on the way the Earth’s shadow interacts with the Moon. Thus, there are three main types of lunar eclipses:

• Total lunar eclipse: This is the most spectacular type of lunar eclipse. It occurs when the Moon, Earth and Sun line up perfectly, with the Earth in the middle. The Moon completely enters the umbra (central shadow) of the Earth and its obscuration is total and evident. During the phase of totality, the Moon can acquire a dark reddish hue, the intensity of which can vary, which is known as a «Blood Moon.»
• Partial lunar eclipse: This type of eclipse offers a partial view of the phenomenon. It occurs when the Moon only partially enters the Earth’s umbra. Only part of the visible, illuminated side of the full Moon is darkened, giving the impression that the Moon has received a «bite»whose size may vary.
• Penumbral lunar eclipse: This is the most subtle type of lunar eclipse. It occurs when the Moon passes through the outermost part of the Earth’s shadow, known as the «penumbra.» The dimming is less pronounced than in other types of lunar eclipse and can be difficult to perceive with the naked eye, especially for inexperienced observers.

The red moon phenomenon during lunar eclipses

During some total lunar eclipses, the Moon can take on a fascinating reddish huea phenomenon popularly known as «blood moon«. This visual effect, which will probably be seen in the total lunar eclipse of March 14, 2025has a curious scientific explanation.

When the Moon is completely immersed in the Earth’s umbra (central shadow), it still receives a residual amount of sunlight. This light, however, does not reach the Moon directly, but is filtered by the Earth’s atmosphere, which acts as a selective filter for sunlight:

• The shortest wavelengths (blue) They disperse more easily when interacting with atmospheric particles.
• The longest wavelengths (red and orange) They manage to cross the atmosphere more easily.

This filtering phenomenon is known as Rayleigh scattering and it is the same process that explains why the sky is blue during the day or the reddish and orange tones at sunrise and sunset.

Why aren’t there lunar eclipses every month?

Many wonder why, since the Moon orbits the Earth every month, we don’t witness a lunar eclipse every month. The answer to this question lies in the complex orbital geometry of our Earth-Moon-Sun system.

The Moon’s orbit around the Earth is not perfectly aligned with the plane of the Earth’s orbit around the Sun. This lunar orbit is slightly inclined with respect to the ecliptic plane (the Earth’s orbital plane) and because of this, on most full moons, our satellite passes above or below the Earth’s shadow. This is why a lunar eclipse does not occur in each monthly cycle.

lConditions for a lunar eclipse occur only twice a year.. On these occasions, the Moon’s path takes it through the shadow cast by the Earth.

Solar eclipses: what they are and when they occur

Solar eclipses are fascinating astronomical events that occur when the Moon passes between the Earth and the Sun, creating a unique visual spectacle. They always occur during the new moonwhen the Moon passes directly between the Earth and the Sun and completely or partially blocks sunlight reaching the Earth.
