Take a look at the rare celestial spectacle of the longest lunar eclipse on Friday night | News from India

THIRUVANANTHAPURAM: A rare set of celestial shadows of the total lunar eclipse that will be of the longest duration for the 21st century can be observed on Friday. Scientists urge everyone not to miss this rare Red Moon show called "Blood Moon" and Red March dazzling in the night sky and are ready to hold awareness sessions with night-sky observation in Kochi and Thiruvananthapuram. Although, a section of scientists have also indicated the possibility of high tides and erosion of the sea along the coast of Kerala.

"The moon will be visible in a" scarlet-red hue "for more than one hour and 43 minutes, 40 percent more than any other recently measured eclipse.The lunar eclipse may be better seen to the naked eye.On observing it at the telescope, the moon will appear enlarged and will be partially visible.We arrange for free night sky observation on the terrace of the Priyadarshini Planetarium from 23:30 July 27th at 3 am on July 28. We will also keep the telescopes ready, so that visitors can get a glimpse of the total lunar eclipse and pay attention to other planets, including Mars the Red Planet ", said Arul Jerald Prakash, director of the State Science and Technology Museum of Kerala (KSSTM), at TOI. It is expected that it will be the longest lunar eclipse observed in 100 years. The Moon will disappear in the darkest shadow of the Earth known as Umbra, he said.

"The total lunar eclipse will be fully visible in Thiruvananthapuram.The partial eclipse will begin at 11:55 pm The total eclipse will begin at 1 am on July 28 and when the moon will be closest from the center of the shadow, the maximum eclipse will be at 1.51 am At 2:45 pm, the total eclipse will end.The partial eclipse will end around 3:45 am The total duration including the entire shadow phase will be six hours and 14 minutes, "he said. The reddish hue of the moon is due to the fact that the Earth has an atmosphere and when sunlight reaches the atmosphere, the gases in the air scatter or bend the light. Its red light that has scattered just the right amount that it ends up being directed to the surface of the moon, "said Arul J Prakash.

It is well known that a lunar eclipse occurs only during the full moon when the moon appears fully illuminated from the Earth. A total lunar eclipse occurs when the Sun, Earth, and Moon are perfectly aligned so that only a minimal amount of sunlight can infiltrate into the atmosphere and so the moon will appear dark. When most of the sun 's blue light is filtered by the Earth' s atmosphere, the sky appears in blue and the least scattered red light infiltrates into the atmosphere and reaches the Moon and makes the moon red. "In addition, when the dust content in the atmosphere is higher or the particles are higher, the sun 's rays refract the red part of the light spectrum and the moon appears blood red, the phenomenon s'. calls the Blood Moon Francis Kulathunkal, a member of the Society (BSS), explains.

Volcanic activity in some continents spews vapors in the atmosphere and with aerosol particles in the atmosphere, it can also cause such a spectacle, he added. Observers in Kerala and parts of Asia can observe the lunar eclipse of the longest duration for three hours, 54 minutes and 33 seconds from the moment the partial eclipse begins when the moon becomes slightly red, he said.

Awareness sessions will be held in schools, colleges and, where possible, in the state. An awareness training with telescopic observation will be held at the Department of Physics at Sacred Hearts College, Thevara, from July 27th to July 22nd at 10:45 pm.

If clouds and heavy rain do not play the spoilsport, astronauts will be able to observe the total lunar eclipse and other planets through telescopic observation organized by KSSTM at Priyadarshini Planetariam, said PP Rajeevan, member and scientist of the BSS. "The lunar eclipse is a simple celestial event and has no harmful effect on human beings.People can safely observe the lunar eclipse to the naked eye.The specialty of this lunar eclipse is that it is the longest lunar of the century.The rise of the sea level will be more or less the same as that which occurs on the day of the full moon ", has-it- he says.

"Spring tides occur during the full moon or new moon, when the Sun, Moon and Earth are aligned and their collective gravitational pull on the Earth increases, which can cause tides along the There is a possibility of large tides and erosion along the coast of Kerala because of the effect of the total lunar eclipse, "said the secretary of Kerala Disaster Management Authority (KSDMA), Sekhar Kuriakose.

KSDMA and the Indian National Center for Ocean Information Services also warned of high waves in the range of 3.5 to 3.9 meters along the coast of Kerala and the possibility of waves along coasts in the lowlands. Kerala.
