Strange interstellar object 'Oumuamua is tiny and very reflective

After no small mystery, we’re beginning to know more about more about ‘Oumuamua, the very first known interstellar object which was known to visit the Solar System. A latest study indicates that the object cannot be that large, for one thing. As the Spitzer Space Telescope’s infrared detection was not able to catch the cigar-shaped entity, which makes it relatively very small. It’s likely less than 2,600 feet at its longest. It also can not have a diameter more than 1,440 feet, and that figure could well be as small as 320 feet.

The research also found something really unusual: it’s a lot reflective, potentially up to 10 times more than Solar System comets. Just what caused it to be like this is not yet certain. It may be possible that ‘Oumuamua lost quite a lot of its surface dirt and dust as soon as it passed across the Sun, which (mixed with gas from the object itself) left it covered in reflective ice as well as snow. This is known to happen with local comets, although not always to this degree.

There’s one big problem with the verifying details: it may possibly be too late. The object is now known to be roughly as far from the Sun as is Saturn, which puts it quite far away for study by the present space telescopes. Whatever its exact nature might be, we may have to wait for a long time for getting more answers — if we get any at all.

Mars could be ‘Terraformed’ by Using Tiles, Scientist Says

You must have seen science-fiction movies where humans terraform other planets by using high technology to change planets into a place where humans can live. Now, in reality, it might be possible to terraform Mars after taking a step to step approach, according to American and British scientists. They believe that using the island of tiles on Mars could create a habitable environment there, and this can be possible in the next few decades.

Scientist could create tiny islands on Mars, which are covered with the lightest material available on Earth. Silica aerogel is a fluffy white powder material that can be used to make an inch thick layer of tiles. Silica aerogel tiles can insulate the surface and create some habitation domes with drinking water. The tiles would be installed in ice-rich temperate regions of the planet to make Mars more realistic for humans.

This grand plan of terraforming Mars is proposed by a joint US and British team and could be executed in the next few decades. It has been tested in lab experiments that 2 cm to 3 cm thick shield of silica aerogel can transmit enough visible light to start a photosynthetic life. On the same time, it also blocks hazardous UV radiation and raises temperature underneath. Some of the Spanish tiles are also layered with silica aerogel to make them ready to install at UV radiation affected areas.

Robin Wordsworth, an engineer at Harvard University in the US, said, “This regional approach to making Mars habitable is much more achievable than global atmospheric modification, unlike the previous ideas to make Mars habitable, this is something that can be developed and tested systematically with materials and technology we already have.”
