A solar eclipse is a rare and mesmerizing celestial event that occurs when the moon moves between the Earth and the sun, casting a shadow on the planet. The upcoming solar eclipse on March 29, 2025, will be a partial eclipse, visible across several continents. This event will provide a fascinating opportunity to observe the interaction between the sun, moon, and Earth. However, safety is crucial—viewing a solar eclipse without proper eye protection can cause irreversible damage.

This guide covers essential details about the timing and location of the eclipse, safe viewing methods, and its effects on the environment and wildlife.
When and Where Will the next solar eclipse Occur?
The next solar eclipse will take place on March 29, 2025, at 8:50 AM UTC. It will be a partial solar eclipse, meaning the moon will obscure only a portion of the sun. The visibility of the eclipse will vary depending on location.
This eclipse will be visible across Europe, northern Asia, large parts of North and South America, northern and western Africa, as well as the Atlantic and Arctic regions. Some regions will experience a deeper eclipse than others, with the exact level of sun coverage depending on geographic position. Weather conditions will also play a role in how clearly the event can be observed.
Understanding the Different Types of Solar Eclipses
Solar eclipses occur when the moon moves between the Earth and the sun, temporarily blocking sunlight. The degree of coverage determines the type of eclipse.
A total solar eclipse happens when the moon completely covers the sun, turning daytime into darkness for a brief period. This occurs only in a narrow path called the path of totality. A partial solar eclipse, like the one in 2025, happens when the moon covers only part of the sun, creating a crescent-like effect. In an annular solar eclipse, the moon appears smaller than the sun, leaving a glowing ring of sunlight visible around the edges.
Each type of eclipse offers a unique viewing experience, but total eclipses are the most dramatic, as they briefly reveal the sun’s outer atmosphere, known as the corona.
How to Safely View the Solar Eclipse
Watching a solar without proper protection can cause serious eye damage. The sun’s intense rays can burn the retina, leading to permanent vision loss (solar retinopathy). Since the retina lacks pain receptors, this damage can occur without immediate symptoms but may result in long-term blindness.
To safely view the eclipse, use ISO 12312-2 certified eclipse glasses, which are specifically designed to block harmful rays. Another safe method is a pinhole projector, which allows indirect viewing by projecting the sun’s image onto a surface. If eclipse glasses are unavailable, welding glass with shade 14 or higher can serve as an alternative. For those using telescopes or binoculars, solar filters are essential to prevent eye damage.
It is important to avoid using regular sunglasses, smoked glass, exposed film, CDs, or DVDs, as these do not provide adequate protection.
The Environmental and Biological Effects of a Solar Eclipse
Solar not only impact the sky but also influence the environment. One of the most noticeable effects is a drop in temperature as sunlight is temporarily blocked. This cooling can also lead to changes in wind patterns, as air pressure shifts in response to the sudden darkness.
Wildlife also reacts to eclipses in fascinating ways. Birds often stop singing, mistaking the dimming light for sunset. Some nocturnal animals, like bats and owls, may become active, believing night has fallen. Meanwhile, daytime animals may begin preparing for sleep, only to resume normal behavior once the eclipse passes.
Historically, solar were viewed with fear and superstition, often seen as omens. Today, they are celebrated and studied, offering valuable insights into astronomy and the sun’s outer layers.
The Next Total Solar Eclipse After 2025
Following the March 29, 2025, partial eclipse, the next total solar will take place on August 12, 2026. This will be a more dramatic event, with the moon fully covering the sun.
The total eclipse will be visible in Greenland, Iceland, and northern Spain, while a partial eclipse will be seen in much of Europe, North America, and North Africa. Those within the path of totality will experience a brief but incredible moment of total darkness, making it a must-see event for eclipse enthusiasts.
