British scientists say they have found water for the first time in the atmosphere of a planet outside our solar system.

Researchers at University College London said Wednesday they found water vapor in a planet’s air 110 light years from Earth that has temperatures suitable for life as we know it.

More than 4,000 exoplanets have been detected, but scientists say it is the only known exoplanet that has water, temperatures needed for life and a rocky surface.

It is not known if the planet, twice the size of Earth, eight times its mass, has water flowing on its surface.

But scientists say the so-called Super Earth is an ideal distance from its sun to conceivably harbor life.

The planet, known as K2-18b, was discovered in 2015 by the U.S. National Aeronautics and Space Administration.

“Finding water in a potentially habitable world other than Earth is incredibly exciting,” said Angelos Tsiaras, lead author of the UCL report that was published in the journal Nature Astronomy. “K2-18b is not ‘Earth 2.0’ but it brings us closer to answering the fundamental question: Is the Earth unique?”

Scientists expect future space missions to detect hundreds of other exoplanets in coming decades.

A new generation of space exploration instruments will be able to describe exoplanet atmospheres in much greater detail.

The European Space Agency’s ARIEL space telescope, for example, is scheduled for launch in 2028 and will observe some 1,000 planets, a sampling large enough to identify patterns and outliers. (VOA)

Shaking head is one of the most common methods people use to get rid of water in their ears, but it can can also cause complications as Researchers have found that trapped water in the ear canals can cause infection and Brain Damage.

Researchers at Cornell University and Virginia Tech in US, revealed that shaking the head to free trapped water can cause brain damage in small children.

“Our research mainly focuses on the acceleration required to get the water out of the ear canal,” said Indian-origin researcher and study author Anuj Baskota from Cornell University.

“The critical acceleration that we obtained experimentally on glass tubes and 3D printed ear canals was around the range of 10 times the force of gravity for infant ear sizes, which could cause damage to the brain,” Baskota said.

For adults, the acceleration was lower due to the larger diameter of the ear canals. They said the overall volume and position of the water in the canal changes the acceleration needed to remove it.

“From our experiments and theoretical model, we figured out that surface tension of the fluid is one of the crucial factors promoting the water to get stuck in ear canals,” said Baskota.

Luckily, the researchers said there is a solution that does not involve any head shaking.

“Presumably, putting a few drops of a liquid with lower surface tension than water, like alcohol or vinegar, in the ear would reduce the surface tension force allowing the water to flow out,” Baskota said.
