Longest lunar eclipse: Mars coming closest ever to Earth in 15 years

"For an especially long-lasting total lunar eclipse of 1 hour and 43 minutes to occur, the moon has to pass through the central part of the Earth's shadow", explains EarthSky. By observing it through telescope, the moon will appear enlarged and will be partly visible. The entrance is free and visitors will get custom bracelets. Those parts of the Moon closer to the edge of the Umbra often appear somewhat brighter and more yellowish than those toward the centre, which are redder.

"This is one of the largest weather events that we've seen on Mars", NASA scientist Michael Smith said in a statement.

In Oman, the partial eclipse will begin around 10.24pm, while total eclipse is expected to begin at 11.30pm. At 2.45 am the total eclipse will end. Before 2017, there was an 8 percent partial eclipse on Dec.31, 2009, but, for a Total Eclipse of a Blue Moon, we have to go all the way back to March 31, 1866. "The total duration including the entire shadow phase will be six hours and 14 minutes", he said.

Red light has a better chance of doing so because shorter wavelengths of light are scattered more efficiently by the molecules in our atmosphere and red has a relatively long wavelength. A new paper was published online today (July 23) in the journal Astrobiology with a thrilling headline: "Was There An Early Habitability Window for Earth's Moon?"

In simple words, Lunar Eclipse is the passage of the Moon through Earth's shadow. Once the moon is fully eclipsed (at around 3.30am), depending on conditions, it may start to appear red due to the sun's light being refracted through the Earth's atmosphere and onto the moon.

On the night of Friday, July 27, the plane on which the moon orbits around the sun will align with the plane on which the Earth revolves around the sun. But there are occasions when they align with the earth in between the sun and the moon.

The volcanic activity in some continents spews up fumes into the atmosphere and with aerosol particles in the atmosphere, it can also cause such a spectacle, he added.

Awareness sessions will be organised in schools, colleges and wherever possible in the state.


The eclipse will dazzle viewers on the evening of 27 July and morning of 28 July.

Lunar eclipses are less common than solar ones but can be seen by more of the Earth.

It is safe to watch the eclipse without any eye protection or special equipment.

This meteor shower favors the Southern Hemisphere with up to 15-20 meteors an hour, but people in the Northern Hemisphere may still be able to spot a few shooting stars around the shower's peak.


In fact, such conditions could have arisen on the moon during two different periods, each tens of millions of years long, the study suggests.

By around 12.30am on Saturday, the moon will completely move out of the Earth's shadow, glowing its usual white colour.
