O telescópio que deve achar 100 mil planetas sozinho decola este mês

There are planets around other stars. They are very far and very small. So they are hard to see. In thirty years, people find about six thousand of them.

Now NASA sends up a new telescope. Its name is Nancy Grace Roman. The launch day is August 30, 2026. Its mirror is the same size as the mirror of Hubble. But it sees a piece of sky one hundred times bigger. So it works much faster.

Scientists want two things from it. First, about one hundred thousand new planets. Second, a map of dark energy, the strange thing that pushes the universe apart. Nancy Grace Roman is a real person. She helps NASA build the Hubble many years ago.
