Not too big，not too small. Not too hot, not too cold. A newly discovered planet looks just right for life as we know it，according to an international group of astronomers。

Circling a star about 500 light years away, the planet called Kepler—186f is about the same size as Earth。

It goes round its star at the right distance for liquid water on the surface。

That is a necessary condition for life。

But it is not exactly like Earth, it’s more of an Earth's cousin. It’s not an Earth's twin。

It shares the same characteristics as Earth, but their parent stars are very different.
Kepler—186f circles a star that is smaller and cooler than our sun。

But the planet appears to be a closer relative than most of the hundreds of others discovered so far。

Some are huge gas-covered giants with thick atmospheres。

Others circle too closely to their stars and are too hot for life。

For the first time，we can actually say we now have a planet that is both Earth-sized and circles in its star’s livable zone。

The next step would be to look for signs of life in the atmospheres of these distant world。

That would take a more advanced telescope。

But budget cuts threaten that task, says University of California at Los Angeles astrophysicist Ben.
“In theory, we could do this in the next couple of decades。

But in practice，because there’s no money，it’s not going to happen. It’s not goi ng to happen in my lifetime, for example, ”said Ben。

However，NASA’s Elisa Quintana believes that when the next-generation space telescope is used, it will find that we are not alone in the universe。

In the meantime，the search continues for other worlds where life may find a home.
