"Tomorrow, the Earth's looming shadow will cover the <keyword id="42440" type="General" weightage="100" keywordseo="moon" source="Orion">Moon</keyword> and during this period it will appear a dark reddish colour, almost like a large drop of blood balanced in the sky... This phenomenon is called a 'Blood Moon' and it's an exciting spectacle," said Prof. Adur. He urged the people to view it wherever possible, as this will be the last total lunar eclipse, and the next one (total lunar eclipse) due only after three years on September 7, 2025. The Earth will come between the Sun and Moon and the blue planet's monstrous shadow -- from a staggering distance of 3.93 lakh kms -- will shroud its small natural satellite, partially or fully, depending on the angle of alignment from where it is viewed, Prof. Adur explained. The Sun is around 109 times bigger than Earth and over 148-million kms away, while the Earth is nearly four times larger than the Moon, with an average distance of 3,85 lakh kms separating them. "In a total lunar eclipse, the Moon is entirely blanketed by the Earth's darkest shadow, called the 'umbra', and at this time, the Moon appears a dark-reddish colour, or what is called the 'Blood Moon' phenomenon," Prof. Adur said. In scientific terms, it's called the 'Rayleigh Scattering' as during a lunar eclipse the only sunlight that reaches the Moon passes through the Earth's atmosphere, thus turning the Moon an apparent reddish colour. This is the second celestial event since the last partial Solar Eclipse (October 25), and can be witnessed by people in India, Pakistan, Afghanistan, parts of Asia, Russia, North and South Americas, Australia, North Atlantic Ocean and Pacific Ocean regions. Despite the scary myths or deep religious aspects associated with any eclipse (solar/lunar), Prof. Adur assured that there is absolutely no harm in viewing the unusual 'Blood Moon' on Tuesday with naked eyes or with binoculars which will enhance the reddish colour. The northeastern parts of India like Kohima, Agartala, Guwahati and other regions in the world will witness it in totality on Tuesday, the final eclipse of 2022. As the Moon will be below the horizon during the eclipse hours, most other parts of India will miss the exciting starting phases of both the partial and total eclipse, he said. Kolkata, New Delhi, Chennai along with Mumbai, can witness only the partial phase, and in the country's commercial capital barely 14 per cent of the Moon's obscuration can be viewed at 18.03 hours in the setting sun. However, the Moon will be seen 60 per cent covered in Nagpur, 66 per cent in Srinagar and in varying degrees in other cities, said Prof. Adur. In case people miss the 'Blood Moon' on Tuesday, they can wait for October 28, 2023, when there will be another partial lunar eclipse that will be visible in some parts of the country, Prof. Adur smiled.

World to witness 'Blood Moon' spectacle in the sky on November 8

Badrinath (Uttarakhand) [India], November 8 (ANI): In view of the <keyword id="12567561" type="General" weightage="20" keywordseo="total-lunar-eclipse" source="Orion">total lunar eclipse</keyword> (Chandra Grahan), the doors of <keyword id="642949" type="General" weightage="20" keywordseo="badrinath-temple" source="Orion">Badrinath Temple</keyword> were closed earlier today and would remain so till late evening. "Badrinath Dham Temple closed for the lunar eclipse. The temple will re-open at 6:25 pm after the eclipse", Ajendra Ajay, Chairman of the Shri Badrinath-Kedarnath Temple Committee told ANI. Due to the Lunar Eclipse, temples across India have been closed since morning and would remain closed till 6:30 pm in the evening. Temples have announced that after performing the <keyword id="6290100" type="General" weightage="20" keywordseo="sandhya-aarti" source="Orion">Sandhya Aarti</keyword> and other rituals for purification, the temples would be opened to the public. A Lunar eclipse happens when the Sun, Earth, and a Full Moon form a near-perfect Syzygy in space. The Moon slides into the Earth's shadow and gradually darkens until the entire lunar disc turns into an eerie red or dim orange from its usual silvery grey shade. The event unfolds in reverse order further, until the moon returns to its full brilliance. The <keyword id="15461656" type="General" weightage="20" keywordseo="november-8th-lunar-eclipse" source="Orion">November 8th lunar eclipse</keyword> is the last lunar eclipse of the year and the second total lunar eclipse in the year 2022, the earlier was on May 15-16th. Today's eclipse would be visible across India along with parts of Asia, North America, Australia, and a few places in Europe as well as in the entire North America. The next Lunar eclipse is predicted to be on the 5th of May, 2023. Every year, from anywhere between four to seven times, the Sun, Moon, and Earth line up in a Syzygy, forming what is called either the Solar or Lunar Eclipse. (ANI)

Others have <a target="_blank" href="https://www.washingtonpost.com/news/wonk/wp/2017/08/18/this-5000-year-old-stone-carving-may-be-the-worlds-first-drawing-of-an-eclipse/">expressed</a> skepticism.Human-made markings on tortoise shells from China and a Babylonian tablet from over 3,000 years ago may also contain ancient references to eclipses.Though these records are open to interpretation, scholars have <a target="_blank" href="https://eclipse.gsfc.nasa.gov/SEhelp/rotation.html">studied</a> historical descriptions of eclipses for centuries. It's how 18th-century astronomer Edmond Halley first realized the <a target="_blank" href="https://www.businessinsider.com/what-if-earth-stopped-spinning">Earth's rotation</a> has slowed over millennia.<h2>2. Discovering what causes eclipses</h2><div type="image" title="Engraving of Pericles stands next to Anaxagoras, who is sitting on steps next to columns in Ancient Greece" height="1500" width="2263" msid="109088912" hostid="261" sizebytes="1159624"></div>Two modern scholars <a target="_blank" href="https://daily.jstor.org/anaxagoras-and-the-eclipse-the-first-to-get-it-right/">give</a> Greek philosopher Anaxagoras of Clazomenae credit for figuring out the moon's role in eclipses, calling him "perhaps the first empirical astronomer."He likely developed his theories after witnessing an annular, or "<a target="_blank" href="https://www.businessinsider.com/october-solar-eclipse-annular-ring-of-fire-where-how-watch-2023-10">ring of fire</a>," eclipse on February 17, 478 BCE. While he got some of the science right, his overall understanding of the solar system was a product of its time.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.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> during an eclipse to estimate its size, but his calculations gave him a much smaller answer than reality.<h2>3.

Greek astronomer Hipparchus would have just been a child at the time, but it's possible he saw the event.Years later, Hipparchus may have used secondhand accounts of that same eclipse to make one of the era's most mathematically accurate estimates of the <a target="_blank" href="https://www.businessinsider.com/mind-boggling-nasa-photo-shows-moon-distance-from-earth-2022-10">moon's distance from Earth</a>.Though Hipparchus' direct writings are lost, a 4th-century scholar <a target="_blank" href="https://journals.sagepub.com/doi/10.1177/0021828618817175">detailed</a> how he used the information.The astronomer estimated the distance between where the total eclipse was in modern day Turkey and Alexandria, Egypt — where a fifth of the sun showed — to make his calculation.Based on his math, Hipparchus offered a few ranges, including a mean distance of about 281,387 miles.He wasn't terribly far off. The moon is about 238,855 miles away.<h2>4.

He was using a spectroscope, a prism-like device for separating sunlight into a spectrum.Janssen saw a yellow line with a wavelength unlike any other element. Around the same time, English astronomer Norman Lockyer developed an instrument for viewing the sun even without an eclipse. He saw the same line.Lockyer called the mysterious element helium.

It fit the data better than a mysterious, difficult-to-spot extra planet.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.In 1919, expeditions traveled to Principe, an island off the coast of Africa, and Brazil.

7 times a total solar eclipse revolutionized science 

New Delhi [India], November 8 (ANI): Today is the day when the world will witness the last total <keyword id="90051" type="General" weightage="20" keywordseo="lunar-eclipse" source="Orion">lunar eclipse</keyword> of this year. At full moon, when the moon is close to a node, total lunar eclipses take place because the earth blocks the sun's rays from reaching the moon. Almost a year after the last total lunar eclipse, the sight of the moon sliding into the shadows of the Earth returns and graces the sky. Viewers in North America, Central America, most of South America, the Pacific Ocean, Australia, New Zealand, and Asia will see the Moon darken and acquire a reddish in the wee hours of Tuesday, November 8. When and how to watch lunar eclipse The Moon traverses the northern half of Earth's shadow, with totality predicted to last 86 minutes. Mid-eclipse happens on November 8th at 10:59 Universal Time (UT), around six days before apogee, when the Moon is farthest from Earth in its orbit. As a result, during the eclipse, the Moon will appear 7 per cent smaller than it does when it's at perigee (closest to Earth), but the difference is imperceptible. The eclipse on Tuesday will be a bit brighter than the one that occurred in May -- especially in the Moon's northern half -- since the Moon doesn't glide as close to the dark center of Earth's shadow. There are several delightful extras viewers can look out for while admiring the eclipse. During totality, Earth's shadow dims the Moon sufficiently for stars to be visible right up to its edge. In addition, Uranus reaches opposition just a day after the eclipse, when it's directly opposite the Earth from the Sun and at its closest and brightest. And on eclipse night the distant planet will be upper left of the red-hued Moon -- binoculars will reveal the planet's pale disk. The farther west you are, the smaller the gap between planet and Moon. Also, the Northern and Southern Taurid meteor showers peak around this time, so eclipse-watchers might be treated to a few meteors streaking across the night sky. All stages of the eclipse occur simultaneously for everyone, but not everyone will see the full eclipse. Weather permitting, observers in western North America will witness the entirety of the event on the morning of November 8, with the partial eclipse phase beginning an hour or so after midnight. In Hawai'i, the totally eclipsed Moon will be directly overhead. Viewers in the central parts of the continent will see all of totality and most of the final partial phases, while those on the East Coast can watch the Sun rise as totality ends. South America will witness the initial phases of the eclipse up to totality, while Central America can enjoy the show a bit longer and see it through the total phase. The eclipse is an early evening event in central and eastern Asia, Australia, and New Zealand, and the Moon rises either during the earlier partial phases or during totality. The actual clock times of the eclipse depend on your time zone. Do's and Don'ts of Lunar Eclipse" Dos Until there is a lunar eclipse, tulsi leaves must be added to food products. Pray for the moon to be released from Rahu's control soon. Before and after the eclipse, take a holy bath to purify your body and spirit. Don'ts During a lunar eclipse, it is typically advised to stay inside and refrain from beginning any new projects or activities. Pregnant women are strictly forbidden from going outside during a lunar eclipse, cutting or sewing any fabric, carrying sharp tools like scissors or blades, or using knives, among other activities that could harm the unborn child. As per belief, people avoid consuming food. Avoid watching the eclipse with your naked eyes The events that happen during a total lunar eclipse are more complex and interesting than many people realize. The Moon's leading edge enters the pale outer fringe of Earth's shadow: the penumbra. You probably won't notice anything until the Moon is about halfway across the penumbra. 1. Watch for a slight darkening on the Moon's left side as seen from North America. The penumbral shading becomes stronger as the Moon moves deeper in. 2. The penumbra is the region where an astronaut standing on the Moon would see Earth covering only part of the Sun's face. 3. The Moon's leading edge enters the umbra, the cone of Earth's shadow within which the Sun's completely hidden. You should notice a dramatic darkening on the leading edge of the lunar disk. With a telescope, you can watch the edge of the umbra slowly engulfing one lunar feature after another, as the entire sky begins to grow darker. 4. The trailing edge of the Moon slips into the umbra for the beginning of total eclipse. But the Moon won't black out completely: It's sure to glow some shade of intense orange or red. 5. Why is this? The Earth's atmosphere scatters and bends (refracts) sunlight that skims its edges, diverting some of it onto the eclipsed Moon. If you were on the Moon during a lunar eclipse, you'd see the Sun hidden by a dark Earth rimmed with the reddish light of all the sunrises and sunsets ringing the world at that moment. 6. The red umbral glow can be quite different from one eclipse to the next. Two main factors affect its brightness and hue. The first is simply how deeply the Moon goes into the umbra as it passes through; the center of the umbra is darker than its edges. The other factor is the state of Earth's atmosphere. If a major volcanic eruption has recently polluted the stratosphere with thin global haze, a lunar eclipse can be dark red, ashen brown, or occasionally almost black. 7. In addition, blue light is refracted through Earth's clear, ozone-rich upper atmosphere above the thicker layers that produce the red sunrise-sunset colors. This ozone-blue light tints the Moon also, especially near the umbra's edge. You'll need binoculars or a telescope to see this effect. 8. As the Moon progresses along its orbit, events replay in reverse order. The Moon's edge re-emerges into the sunlight, ending totality and beginning a partial eclipse again. 9. When all of the Moon escapes the umbra, only the last, penumbral shading is left. Sometime later, nothing unusual remains. The event has five stages, each with different things to watch.(ANI)
