Scientists have discovered the first Earth-sized planet. It was first marked by scientists’ using NASA’s Kepler telescope(望远镜), so it’s called Kepler-186f. It lies about 500 light years from Earth and goes around its star. The planet is the right distance from its star for water: not too close or not too far. Water is one important condition that scientists guess is necessary for life. So it could have water and possible life. It’s called a true Earth cousin.

“This planet is an Earth cousin, not an Earth twin, ”said Barclay, who is among a team of scientists reporting on the discovery in the magazine Science this week.

“It’s very exciting to find a planet similar to the Earth, ”Barclay said. “It’s not easy work because things change as we get more measurements.”

Scientists don’t know anything about the air of Kepler-186f, but it will be a task for future telescopes which can study for chemicals that have something to do with life.

“It’s possible for life to live in this planet, but that doesn’t mean there is life in it,”Barclay said.

So far, scientists have found nearly 1, 800 planets in the universe.

“The past year has seen a lot of progress in the search for Earth-like planets. Kepler-186f is very important because it is the first planet that is the same temperature and is almost the same size as Earth, ”scientist David Charbonneau wrote in an email.

Dear Died,

Today I was at the shopping centre and I spent a lot of time reading the Father’s Day cards. But as I chose add read, and chose add read again, it seemed that not a single card said what I really wanted to you.

You’ll soon be 84 years old, Dad,and you and I will have had 56 Father’s Days together. I didn't think that you were too old. But the sad thing happened last week. I watched as you turned at the corner in your car. I didn’t realize at once that it was you because the man who was driving looked so elderly.

Fifty years ago this spring, we planted carrots together in a garden in Charles City, Iowa. This week, we’ll plant carrots together again, perhaps for the last time but I hope not. I don’t understand why planting carrots with you is so important to me. Well, I don't quite know how to tell you this, dad … I don't like carrots.... but I like planting them with you.

I guess what am trying to say, Dad, is what every son and daughter wants to say to their dad today. Praising a father on Father's Day is about more than a dad who brings home, money or shares a dinner. It’s more about a dad deeply loving children who know everything and won't listen to anyone. It's about sharing. It’s about loving someone more than words can say, and I wish that it would never end.

Lover,

Jenny
