Earth's moon could have supported life billions of years ago

Scientists believe there could have been life on the moon millions of years ago

The eclipse on Friday is set to be the longest of the 21st Century, as the full moon happens to coincide next month with the point at which the moon's orbit is furthest away from the earth, so it will take longer to pass through the earth's shadow. Observers in Kerala and parts of Asia can witness the lunar eclipse of the longest duration for three hours, 54 minutes and 33 seconds from the time of partial eclipse begins when moon turns slightly red, he said. That's why lunar eclipses are also called blood moons. The eclipse will be visible across wide swathes of the world, including Europe, Asia, Australia, Africa, South America and the Middle East.

As it lines up with the Earth and sun, the rising full moon will darken and change from silver to rusty or awful blood red.

In a attractive coincidence, on July 27, Mars will also appear large and bright in the sky as it moves towards its closest approach to Earth in 15 years.

It is well known that a lunar eclipse occurs only during full moon when the Moon appears fully illuminated from the Earth. He said from that moment, more of the moon will get covered by the Earth till totality occurs at 3.49 am.

This event is not to be confused with a total solar eclipse like the one that was visible across a swath of the continental U.S. last summer.

Unlike with solar eclipses, lunar eclipses are less common and safe to watch meaning you can view it without using protective eyewear.

Across the world, from the Taj Mahal to the Eiffel Tower, people will turn their eyes to the sky, hoping to see the blood moon, which appears orange, brown or crimson as sunlight is bent through the earth's atmosphere.

"In the middle of a lunar eclipse it can look as if a red planet has taken up residence near the Earth - they are both eerie and attractive and I'll certainly be looking out for it!" These events will play out simultaneously over the night sky, on the final hours of July 27, and the early hours of July 28.

Well, sky-watchers in the Americas are out of luck this time around. The event can be observed in a large part of the globe, including in India, where it can be seen after 11.54 pm Indian Standard Time on July 27.

The next lunar eclipse of such a length is due in 2123.

"Sometimes, the moon passes through the lighter part of Earth's shadow, causing a penumbral eclipse and total eclipse occur when the Earth completely block Sun rays from reaching the moon", he said.

The path of the moon through the Earth's shadow is more central than during the first eclipse of 2018.

The Red Planet will make its close approach on July 31 at a distance of about 35.8 million miles, according to NASA.

Mars will also appear brighter than usual, appearing just below the blood moon, while the gas giant Jupiter will also be visible to the naked eye to the south-west.
