A period of remarkable astronomical activity is approaching, with a series of three consecutive total solar eclipses predicted to occur between 2026 and 2028.
The sequence of phenomena will offer unique opportunities for observing the solar corona, the outer atmosphere of Sol, which is only visible to the naked eye during the totality phase of an eclipse. The expectation is that each event will boost so-called “astronomical tourism”, with thousands of people planning trips to position themselves within the narrow band of shadow cast by Lua on Terra.
The scientific community is already mobilizing to make the most of these events. Equipes research teams are developing projects to study the solar corona, the Earth’s magnetosphere and even test aspects of Einstein’s theory of general relativity. The succession of eclipses in different parts of the globe will allow the collection of valuable comparative data to deepen knowledge about our star.
The first major event in the Arctic and Europa
The series will begin on August 12, 2026, with a total solar eclipse that will be the first visible on the European continent since 1999. The path of the lunar shadow will begin over the vast and remote region of Ártico, in Groenlândia, where daytime darkness will provide a dramatic backdrop. From there, the path of totality will cross west of Islândia, offering a spectacular contrast between the darkened sky and the island’s volcanic landscapes. The phase of totality in this event will have a maximum duration of approximately 2 minutes and 18 seconds.
After crossing Atlântico Norte, the shadow of Lua will touch north of Espanha in the late afternoon, providing a rare total eclipse at sunset. Cidades as well as La Coruña, Oviedo and Palma of Maiorca will be in the path of totality, attracting a large number of observers. Local authorities and tourism operators are already preparing for the significant increase in visitor flows, organizing viewing areas and special events to mark the occasion. The combination of an astronomical phenomenon with the sunset scene over the sea Mediterrâneo or the ocean Atlântico creates a high expectation for memorable images.
The longest running show in the north of África
The second event in the series, on August 2, 2027, is one of the most anticipated in recent decades due to its extraordinary duration. Totality will peak at 6 minutes and 23 seconds, a considerably long time that has not been recorded on land since 1991.
The path of this eclipse will pass through the southern tip of Espanha and cross Estreito of Gibraltar, passing through several countries of Norte of África, including Marrocos, The city of
This long duration is of immense value to scientists, as it allows for extended observation time of the solar corona. Espera Scientific expeditions from around the world are expected to focus on the region to conduct detailed experiments, taking advantage of the favorable weather conditions, especially in the Egyptian desert, which historically has clear skies at this time of year.
Oceania’s turn in 2028
The trilogy of major eclipses will end on July 22, 2028, with an event that will mainly benefit Austrália and Nova Zelândia. The shadow of Lua will pass across a vast area of the Australian continent, with the city of Sydney positioned directly in the path of totality. Milhões people will have the chance to witness day turn into night for more than five minutes, one of the most significant astronomical events to occur in a major global metropolis this century. The eclipse will cross the country from northwest to southeast, passing through iconic locations and remote areas before heading to Ilha Sul from Nova Zelândia. Cidades like Queenstown and Dunedin will also experience totality, albeit for a shorter duration. The event is expected to generate enormous local and international interest, with preparations already underway to ensure the necessary security and infrastructure to accommodate observers.
Preparations and safety recommendations
Observing a solar eclipse requires strict care to avoid permanent damage to your vision. Olhar directly onto Sol, even for a few seconds or when partially covered, can cause retinal burns, a condition known as solar retinopathy.
It is essential to use appropriate and certified protective equipment. The safest way to observe the partial phases of the eclipse is through special eclipse glasses, which must have the international ISO 12312-2 certification.
Improvised methods such as ordinary sunglasses, veiled photographic films, x-rays or tinted glasses are not safe and should be avoided at all costs, as they do not block infrared and ultraviolet radiation, which are invisible but extremely harmful to the eyes.
For those planning to travel to totality areas, it is advisable to book flights and accommodation well in advance. Demand for these services often exceeds supply, resulting in increased prices and sold out months before the event.
Renewed scientific and cultural interest
Each total eclipse is a valuable opportunity for science. Observing the solar corona, which is millions of times less bright than the surface of Sol, makes it possible to study its complex structure, its extremely high temperature and the mechanisms that generate the solar wind, a flow of particles that affects the entire solar system, including Terra.
In addition to their scientific value, these events have a strong cultural and social appeal. The experience of witnessing sudden daytime darkness, falling temperatures, and animal behavior creates a deep connection with the cosmos, uniting people of different cultures and backgrounds in a shared appreciation of the universe.
Other phenomena on the horizon
While the 2026-2028 sequence is the highlight, other total solar eclipses are on the astronomical calendar for the next decade. A notable event will occur on November 25, 2030, with a path of totality that will cross south of África, passing through Namíbia and Botsuana, before ending at Austrália, reinforcing this period as a particularly rich era for eclipse chasers.
