SUN ECLIPSE. A total solar eclipse took place on Monday April 8, 2024, on the American continent. It was not visible in Europe, but many images and videos were shared on social networks.
[Mis à jour le 8 avril 2024 à 22h36] This Monday, April 8, 2024, residents of North America were able to witness a rare spectacle in the sky. A total solar eclipse, a phenomenon that occurs when the Moon temporarily obscures the entire Sun, occurred in the afternoon on the other side of the Atlantic. This total eclipse, the 15th of the 21st century, is particularly rare due to the maximum duration of its centrality phase estimated at 4 minutes and 34 seconds.
There NASAthe American space agency, broadcast the entire eclipse live on its YouTube channel with interventions from specialists and several personalities to follow the event up to the minute.
In the United States, many Americans took the day off. Some found themselves in parks to admire the eclipse using adapted lights, as can be seen in the tweet below, at a university in Washington.
At Niagara Falls, on the border between the United States and Canada, the eclipse was not total, but the images are still impressive. It was night in broad daylight, as evidenced by this video.
The luckiest were the Mexicans for whom the duration of the night was longer. The spectacle was most spectacular in Nazas, a city in northwestern Mexico since it is located in the heart of the “band of totality” of the eclipse. Some people have even traveled to Nazas to admire this phenomenon, like this Internet user. She says she had an incredible moment.
See the eclipse is incredible!

Aún que en el video no lo parece, en el momento había totally dark as if there was no night pic.twitter.com/GaDoS7MRaY— Mariana Dmz B () (@DmzMariana) April 8, 2024
The solar eclipse of April 8, 2024 crossed a perimeter of approximately 185 kilometers in North America, starting on the Pacific coast of Mexico, crossing the United States through the states of Texas, Oklahoma, Finally, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire and Maine in Canada, crossing southern Ontario then Quebec, New Brunswick, Prince Edward Island and Cape Breton. The eclipse ended on the Atlantic coast of Newfoundland, Canada.
If in France, the next eclipse of sun total will not take place before September 3, 2081, other annular or partial solar eclipses may be observed between now and then.
A solar eclipse occurs when the Earth, Moon and Sun are perfectly aligned in the same plane. The Moon then projects its shadow on the Earth, thus masking the Sun, and plunging part of our planet in the dark for a few minutes.
The Earth revolves around the Sun in a plane called the “ecliptic plane”. The Moon, for its part, revolves around the Earth in another plane. Thus, at the new Moon, when our satellite is located between the Earth and the Sun, it is generally not aligned perfectly with them. This is why there is no solar eclipse every new moon. Exceptionally, all the conditions are met: Earth, Moon and Sun are aligned in this order on the ecliptic plane. A solar eclipse then occurs.
A partial solar eclipse occurs when the Earth-Moon-Sun alignment is not perfect, when the Moon passes slightly above or below the Earth-Sun alignment. The Moon only hides a piece of the Sun, which is not enough to completely darken the sky. “To begin to have a sensation of darkness in the sky, to perceive a sort of cold light, you need at least 95% obscuration of the Sun,” Florent Deleflie, astronomer at the Paris Observatory, told AFP. . This astronomical phenomenon of partial solar eclipse, which occurs when the Sun, Moon and Earth are imperfectly aligned, does not darken the sky and is only observable with protection. adequate, under penalty ofirreversible retinal burns”, warns Florent Deleflie, of the Paris Observatory.
Between the partial and total eclipse, the annular eclipse occurs when the Sun and Moon are perfectly aligned with the Earth but the apparent size of the Moon is slightly smaller than that of the Sun. This then forms a bright ring surrounding the lunar disk. The next annular eclipses will be visible completely from France on the following dates: November 5, 2059 then February 27, 2082.
On Tuesday October 25, 2022, a partial solar eclipse was visible in the sky in France. However, the Sun had not been hidden in the same way depending on the region. Indeed, it was in the east of the country that the partial eclipse was most visible. In Strasbourg, the obscuration rate was almost 20%. Even at the peak of the eclipse, over Kazakhstan, the Sun was more than 80% hidden. An insufficient figure to have a perception of darkness in broad daylight, since an obscuration of at least 95% of the Sun is required.

The next solar eclipses visible from France will be partial. A partial eclipse shows only part of the Sun obscured by the Moon. They will be visible in France on the following dates: March 29, 2025 and the August 12, 2026.
An extremely rare phenomenon, a total solar eclipse only occurs when the Sun, Moon and Earth are aligned perfectly. French astronomy enthusiasts will have to be patient. The next total solar eclipse in France will take place on September 3, 2081followed closely by a second complete eclipse on September 29, 2090. In the meantime, it will still be possible to see the Moon partially obscure the Sun.
If you want to enjoy the spectacle of a total solar eclipse in Europe, you will have two chances to see one… August 12, 2026 First, darkness will cover northern Spain and part of Iceland. This total solar eclipse will only be partially visible in France. The next year, August 2, 2027, a second total eclipse will be visible in the far south of Spain. If you stay in France, you will still be able to enjoy a very beautiful partial eclipse.
To observe a solar eclipse with the naked eye, you must wear special glasses. Classic sunglasses are not enough to protect the retina. During the eclipse, with the decrease in brightness, the pupils will tend to dilate. When the sun suddenly reappears, serious retinal damage can occur. These burns are not painful, so you should be particularly wary of them.
Tricks like watching the eclipse through a CD or through smoked glass are not effective. To protect your eyes and make the most of the eclipse, go to an astronomy club where you can observe the eclipse indirectly through projection. The simplest solution: make a small hole in a piece of cardboard, point it towards the sun and observe the projected eclipse. Please note that glasses allowing you to observe the eclipse without danger are available for around 2 euros. It is also possible to buy them in shopping centers or in stores such as Nature et Découverte, or to order them on the Internet.
