# A telescope the size of a shoebox just found its first planet

A satellite small enough to carry under one arm has found a planet orbiting another star, its university team announced on Monday. It is the first planet discovered by a spacecraft of its size, and astronomers say it could change who gets to look.

The satellite, nicknamed Wren, was built by about forty students at a mid-sized public university over four years. It carries a telescope with a lens about the width of a coffee cup. For eighteen months it stared at a few hundred bright stars, measuring their brightness every few seconds.

## A tiny dip

The method is old. When a planet passes in front of its star, the star dims very slightly. Big observatories have used this to find thousands of planets. Wren’s team wanted to know whether a cheap instrument could do the same for the brightest, closest stars.

In March the data showed a dip of about one percent, repeating every 4.2 days. That’s the signature of a large gas planet hugging its star, a type astronomers call a “hot Jupiter.” Follow-up observations from two ground telescopes confirmed it.

“We kept waiting for someone to tell us it was a glitch,” says Imani Torres, the graduate student who led the data analysis. “Nobody did.”

## Why size matters

Wren cost less than a single instrument on a flagship space telescope. Its parts are mostly off the shelf. That matters because time on the big observatories is scarce, and they rarely spend weeks watching one bright star.

Small satellites can. A fleet of them could keep watch on the nearest stars continuously, catching planets that only cross once a month or once a year.

> “This won’t replace the big telescopes. It frees them to do the things only they can do.”

## What’s next

The planet itself is not a candidate for life. It is far too hot. But the team says its real value is as a proof of concept. They’re already building a second satellite with a slightly larger lens, and two other universities have asked for the design files, which the team plans to publish openly next year.

Wren is expected to keep working until its orbit decays in about three years. Until then, it will keep watching.
