Northern lights, star explosions, solar and lunar eclipses: 2025 promises to be an exciting year for astronomers. Here are the main expected events:
A NEW STAR: In 2025, a new star should appear in the firmament, at least for a few days. According to astronomers, everything has indicated for months that a stellar explosion will occur in the “T Coronae Borealis” system, located 2700 light years from Earth. In this symbiotic binary system, two suns orbit: a white dwarf and a red giant. The white dwarf sucks matter from its companion. At one point, she can’t take it anymore and discharges in a huge nuclear explosion. The resulting so-called “recurring” nova then shines for about a week, as bright as the North Star. This happens about every 80 years. The last nova in this system occurred in 1946 and the phenomenon could well happen again in 2025.
TWO PARTIAL SUN ECLIPSES: In 2025, the Sun will partially eclipse twice, but only the first eclipse, on March 29, will be visible from Switzerland. The Moon will begin to move in front of the Sun at 11:17 a.m. and the highest point of obscuration will be reached at 12:04 p.m. At that time, the Sun will be 14% obscured above Bern. The second partial eclipse, on September 21, 2025, will only be visible from the South Pacific and New Zealand. The next total solar eclipse will not take place in Switzerland until September 3, 2081.
TWO LUNAR ECLIPSES: Two eclipses are also planned for the Moon in 2025. On March 14 and September 7, the Earth will come between the Moon and the Sun, completely obscuring the Moon. The first, however, will not be entirely visible in our country. When the Moon sets in Bern at 6:50 a.m., it will only be partially eclipsed. During the eclipse of September 7, the Moon will, however, be completely in the Earth’s shadow as soon as it rises at 7:55 p.m. From 8:52 p.m., the first rays of the Sun will once again reach the edge of the lunar surface.
BOREALIS LIGHTS: In 2025, the Northern Lights should again be visible in our latitudes due to strong solar activity. The sun becomes more or less active in an 11-year cycle. The current solar cycle has recently peaked, meaning it is still in a particularly active phase. In 2025, the number of solar storms affecting the Earth’s atmosphere should therefore be similar to that of 2024.
