Sara Seager, MIT astrophysicist has been looking for planets outside the solar system. She says she wants to find another Earth. Planets beyond the solar system are called exoplanets and Seager is found searching for exoplanets for almost 20 years.
When Seager was a graduate at Harvard searching for a topic for her Ph.D., she was fascinated by the idea of newborn field of faraway planets.
During 1990s the first ones were explored but it was found questioned by many. Also, nobody thought it was real, but with the help of better technology, today we can see more than 6,000 of them. They are mostly giant balls of gas. The list is found growing every week.
As the list is increasing, Seager wants to distinguish and identify one that resembles Earth; a world with liquid water and where life is possible. She believed in herself in making that discovery.
Exoplanets are however not easy to see even through a telescope. This is because of the blinding light that comes from their host stars, which are of various sizes and features as compared to our sun.
When the first ones were discovered, they were discovered indirectly in response to the pull of another object’s gravity. They would wobble slightly. But the wobble can also be caused by another star and this is the same reason for having several planet discoveries retracted.
Now, a different technique has been found in order to make the search easier which is called transit. Transit is when a planet moves in front of its host star and makes the star’s light to dim slightly.
It was found exoplanets were real when transit was shown from one of the planets from the wobble technique.
Award-winning architect kazuyo Sejima has created a design of an almost invisible train which is believed to be scheduled in Tokyo in 2018.
The design made by Sejima is a reflective train to accompany with changing surroundings. This means that as the Japanese commuter train moves, it will automatically blend into changing scenery whether it’s traveling through the city or country side. This happens all because of the semi-reflective and semi-transparent materials.
As said by Sejima, “the train travels in a variety of different sceneries, from the mountains of Chichibu to the middle of Tokyo, and I thought it would be good if the train could gently coexist with this variety of scenery”
One of the Japan’s leading architect, Sejima established SANAA architecture firm in 1995 with Ryue Nishizawa. His company is well known for its use of light and space and also owns a Seibu Railways which runs around Tokyo and Saitama prefectures. On 100th anniversary of Seibu Group, Sejima was commissioned to create a design of such a nearly invisible train.
Sejima and Nishizawa keep exploring the phenomenal properties of continuous space, transparency, lightness and materials to create a delicate synthesis. They both were both honored by Pritzker Architecture Prize laureates in 2010 which is considered as highest architecture’s honor.
In this twenty first century we people believe on science,its invention and facts proved by the scientist and researchers.
But still there are the questions raised by seeing some of the things.We can find its two sides. In one side it is justified by the researchers while in the other hand we come to the comparison and with lots of questions with how and why???
Similar facts of science has been represented by a channel on YouTube that is “BuzzFeedBlue”. The facts listed by BuzzFeed Blue is not only enlightening but entertaining too.
The backbenchers may find this video quiet interesting as it reveals the practicality of science rather than just the normal textbook information.
So dear science lovers here is a treat for you all, especially, the ones who like reading weird facts.Watch the above video, it will definitely amaze you.
