<keyword id="6699518" type="UNKNOWN" weightage="20" keywordseo="solar-eclipse">Solar eclipse</keyword> is a rare and highly interesting astronomical event that has triggered human imaginations for so long. Solar eclipse occurs when the moon passes between the earth and the sun hiding sun partially or fully for a brief period when seen from the earth. The solar eclipse that is coming up in this season will be an ‘Annular Solar Eclipse’ that will occur on December 26, 2019. This eclipse will be the third and the final solar eclipse for the year 2019. <br /><br /><strong>About Annular Solar Eclipse</strong><br /><br />An annular Solar Eclipse will result when the apparent diameter of the moon is smaller than that of the sun. In this case, the moon will block most of the sun’s light and cause the sun to look like a ring (annulus) and hence the name annular solar eclipse. An annular solar eclipse will be a spectacular sight in the regions where it will be visible. <br /><br /><strong>Regions where annularity will be visible during December 26, 2019 solar eclipse</strong><br /><br />The regions in which the annular solar eclipse will be visible will include Saudi Arabia, Qatar, United Arab Emirates, Oman, India, Sri Lanka, Malaysia, Indonesia, Singapore, Northern Mariana Islands, and Guam. People living in cities like Kozhikode, Coimbatore, Jaffna, Trincomalee, Sibolga, Batam, Singapore, Singkawang and Guam can see the annular solar eclipse clearly in its entirety. Cities like Doha, Madurai, Pekanbaru, Dumai, Johor Bahru and Kuching occur in the regions that will narrowly miss the annular solar eclipse.<br /><br /><strong>The best places in India to view the annular solar eclipse</strong><br /><br />The December 26, 2019 solar eclipse will be annular and partial depending on the location from where you see the eclipse in India. In the states of Tamil Nadu and Kerala, annular solar eclipse will be visible. The longest duration of annularity will be 3 minutes. In Tamil Nadu, you can see the annularity for 3 minutes 11 seconds in Tiruppur and for 3 minutes and 15 seconds in Ammapattinam on the east coast. The annularity will last for 3 minutes in Ooty and since it is a hill station with an altitude of 2200 meters, this location will lead to the best view of the solar eclipse without being obstructed by the clouds. <br /><br /><strong>Timing of the solar eclipse December 26, 2019<br /></strong><br />The partial eclipse will begin a few minutes after 8 am (IST) and will last till 11:30 am (IST). The timing of the annularity will be 09:24 am to 09:27 am in the east coast and 09:31 am to 09:35 am in the west coast. <br /><br /><strong>The percentage of eclipse in different cities of India</strong><br /><br />The maximum obstruction of the sun during the eclipse when seen from different cities of India will be 78.8% from Mumbai, 44.7% in Delhi, 89.4% in Bangalore, 74.3% in Hyderabad, 66.0% in Ahmedabad, 84.6% in Chennai and 45.1% in Kolkata. Some important cities in the annular path of the solar eclipse will be Kozhikode in Kerala, Mangalore in Karnataka and Tiruppur, Coimbatore and Trichy in Tamil Nadu. <br /><br /><br /><br />

Solar Eclipse: The best places in India to view the annular solar eclipse

<ul class="summary-list"><li>2026 will be Europe's first total solar eclipse in 27 years.</li><li>Travelers worldwide will likely head to Spain, Iceland, and Greenland for the event.</li></ul><p>It'll be two decades before the <a target="_blank" href="https://www.businessinsider.com/why-2024-total-solar-eclipse-cool-best-special-nasa-2024-1">next total solar eclipse hits the US</a>.</p><p>Another option: hop on a plane to Europe and turn the 2026 total solar eclipse into a viewing vacation.</p><p>Eclipse cartographer Michael Zeiler at <a target="_blank" href="http://GreatAmericanEclipse.com">GreatAmericanEclipse.com</a> told <a target="_blank" href="https://www.space.com/most-crowded-places-for-total-solar-eclipse-april-2024">Space.com</a> that up to 3.7 million people likely traveled for the solar eclipse on Monday.</p><p><a target="_blank" href="https://www.hotelplanner.com/">HotelPlanner's</a> chief communication officer, Philip Ballard, told Business Insider that the eclipse was a major revenue generator for many cities. For places like Austin, Texas, and Rochester, New York, it could have created $1 billion in revenue, <a target="_blank" href="https://www.vox.com/24121414/solar-eclipse-power-awe">Vox</a> reported.</p><p>"I would say the total solar eclipse has become a global phenomenon," Ballard said.</p><p>Ballard added that the next <a target="_blank" href="https://www.businessinsider.com/solar-eclipse-photos-totality-us-2024-4">solar eclipse</a>, which will pass through Iceland, Greenland, and Spain on August 12, 2026, could result in similar tourism and revenue influxes.</p><p>And if travelers are considering a trip to Europe for the solar eclipse, Ballard recommends planning your trip now.</p><div type="image" title="beach mallorca" height="1124" width="1500" msid="109204998" hostid="261" sizebytes="181458"></div><h2>Determine your eclipse viewing destination</h2><p>According to <a target="_blank" href="https://www.space.com/total-solar-eclipse-2026-a-complete-guide">Space.com</a>, 2026 will be Europe's first total solar eclipse in 27 years. Its path will go through Greenland, parts of western Iceland, and northern Spain.</p><p>Choosing where to watch the eclipse will be a tough and important decision for travelers.</p><p>Iceland and Greenland have some positives. These regions will experience longer totality times, so viewers can watch the eclipse longer. Plus, the sun will be higher in the sky, so finding a spot to watch the eclipse will be less challenging, Space.com reported.</p><p>The downside is that these regions are more likely to be cloudy, according to the outlet.</p><p>While parts of Spain are likely to offer clearer skies, the eclipse's timing will be shorter and closer to the horizon, which means travelers will need to plan and track down a viewing location with unobstructed views of the western horizon, Space.com reported.</p><p>Regardless of the destination, according to the outlet, one bonus is that the strongest meteor shower in the Northern Hemisphere will happen the following night, so travelers can pack two events into one trip.</p><h2>Book flights and hotels far in advance</h2><p>Ballard encouraged people to book their hotels in their destination of choice as far in advance as possible.</p><p>"You should start looking now and booking hotels now because those cities in the path are already going to be at peak season," Ballard said.</p><p>Ballard said it's similar to when a Super Bowl city is determined or a Taylor Swift tour date is announced — you immediately see spikes in bookings. He predicts hotel occupancy rates will hit near-record highs, and room prices may double around the solar eclipse date.</p><p>Ballard's general rule of thumb is to book international travel at least three months in advance, but since this is such an anticipated event, booking earlier is smart. His advice is to start discussing plans with friends and family. If you decide on a destination, book a refundable room to keep your options open if plans change.</p><p>Regarding purchasing a plane ticket, <a target="_blank" class="" href="https://affiliate.insider.com?h=80a023675c3a86f2b99a0adcd5199dfd269a7852dc1755076e603a8495d4feb5&amp;postID=6616970c3d4b1e890435d6ac&amp;postSlug=plan-trip-next-total-solar-eclipse-spain-iceland-greenland-2024-4&amp;site=bi&amp;u=https%3A%2F%2Fwww.expedia.com%2Fstories%2F2023-flight-hacks%2F">a study from Expedia</a> states that international travel's sweet spot is at least six months in advance.</p><p>According to Expedia, travelers who book six months in advance save an average of 10% more than travelers booking within two months or less.</p><h2>Skip the hassle of planning altogether and book a solar eclipse tour</h2><p>Another option is to let a tour operator do the work for you. A handful of tour companies have seen the increased interest in the solar eclipse and launched tours designed around the event.</p><p>These tours will have predetermined locations to view the eclipse, hotel blocks reserved, and itineraries highlighting both the region and the eclipse.</p><p>However, these can sell out quickly. For example, <a target="_blank" href="https://skyandtelescope.org/astronomy-travel/spain2026/">Space and Telescope</a> created an 11-day tour of Spain around viewing the 2026 solar eclipse. The tour has already sold out as of Wednesday, and the waitlist is full.</p><p>Other operators, such as <a target="_blank" href="https://www.wildernesstravel.com/trip/total-solar-eclipse-2026-northern-spain/">Wilderness Travel</a> and <a target="_blank" href="https://www.eclipsetraveler.com/tour/2026-spain-9-nights-total-solar-eclipse-journey/">Eclipse Traveler,</a> have similar itineraries for the total eclipse in 2026.</p>

A very rare supermoon eclipse of the sun is happening this week that won't take place again until 2034

<p></p><div class="KonaFilter image-container display-table float_right"><div><div class="image on-image"></div><p></p></div></div>On Tuesday, March 8, the celestial event of the year will take place: a total eclipse of the sun, which happens when the Moon passes between Earth and the sun, blocking&#xa0;the sun from view.<p>This is the only total solar eclipse we'll see this year, but sadly for the US, only people in certain parts of South East Asia will witness&#xa0;the total eclipse.</p><p>Moreover, others, in parts of Alaska, Hawaii, Guam, and America Samoa will experience&#xa0;a partial solar eclipse, when the Moon eclipses part of the sun.</p><p>Though the rest of us cannot observe this spectacular event first-hand, NASA and the Slooh Community Observatory will be hosting live coverage of the eclipse.</p><p><strong>NASA's coverage begins at 8 p.m. ET and Slooh's starts at 6 p.m. ET on Tuesday, March 8.

While he got some of the science right, his overall understanding of the solar system was a product of its time.</p><p>Anaxagoras, for example, thought that air pressure kept the <a target="_blank" href="https://www.businessinsider.com/what-living-on-flat-earth-would-look-like-2017-11">flat Earth</a> aloft at the center of the rotating sun, moon, and stars.

He was also accurate in his theories that when the moon moved in front of the sun, it caused a solar eclipse. Similarly, when the Earth was in between the sun and moon, there would be a lunar eclipse.</p><p>He also used the <a target="_blank" href="https://www.businessinsider.com/how-lunar-eclipses-work-earth-moon-red-shadow-2018-7">moon's shadow</a><strong> </strong>during an eclipse<strong> </strong>to estimate its size, but his calculations gave him a much smaller answer than reality.</p><h2>3.

In 1915, Albert Einstein <a target="_blank" href="https://www.nbcnews.com/mach/science/einstein-showed-newton-was-wrong-about-gravity-now-scientists-are-ncna1038671">explained</a> Mercury's unusual orbit with his general <a target="_blank" href="https://www.businessinsider.com/albert-einstein-thought-experiments-2023-10">theory of relativity</a>. It fit the data better than a mysterious, difficult-to-spot extra planet.</p><p>Despite this evidence, Einstein's theory didn't receive scientific proof until the May 29, 1919 eclipse. The physicist had said the sun's gravity would bend light from nearby stars.</p><p>In 1919, expeditions traveled to Principe, an island off the coast of Africa, and Brazil. While the moon blocked the sun, the astronomers took photographs.</p><p>The stars seemed to have shifted locations compared to the reference photos. The apparent new locations showed the sun was bending the light within the measurements that <a target="_blank" href="https://www.businessinsider.com/russell-einstein-manifesto-nuclear-weapons-bombs-danger-2024-2">Einstein predicted</a>.</p><h2>7.

The November 12, 1966 eclipse moved from Peru to Brazil, and the astronauts hovered near the path of totality.</p><p>It was a coincidence that they were close enough to see it, according to <a target="_blank" href="https://www.smithsonianmag.com/smart-news/a-history-of-total-solar-eclipses-seen-by-astronauts-from-outer-space-180983909/">Smithsonian Magazine</a>.

NASA also launched over two dozen rockets to study <a target="_blank" href="https://www.businessinsider.com/why-sunscreen-is-not-enough-to-protect-you-from-sun-2023-9">UV radiation</a> and solar X-rays during the phenomenon.</p><p>The agency still uses rockets to gather data during eclipses and will launch three on April 8.</p>
