TESS

A NASA satellite has found a new world with a radius similar to the gas giant Jupiter, but with a fraction of its mass, where a year lasts just over three days.

Using the TESS exoplanet-hunting space telescope, astronomers have found a binary star system where an object erratically spews thick, light-blocking dust.

One of the lightest exoplanets ever discovered, GJ 367b has a surface temperature of over 2,700 degrees Fahrenheit, and orbits a red dwarf star.

The extreme exoplanet is so close to its star that it is the fastest planet of its type ever found.

"I was pretty excited. Coming into the internship, it would be hard to say that I expected to find a planet," Wolf Cukier said.

The three planets are among the smallest and closest exoplanets found to date, according to astronomers.

One of the candidate planets has a water-like density.

The video also shows stars, asteroids and even an arc of stray light from Mars.

TESS may uncover planets that have the right conditions for life to exist.

The test photo includes more than 200,000 stars.

To date, astronomers have confirmed 3,717 exoplanets—all in less than three decades.

NASA hopes the craft will find tens of thousands of exoplanets.

This is what NASA's brand new telescope can and can't learn about exoplanets.

TESS will scour the skies for signs of undiscovered worlds.

Scientists are excited about the prospect the mission holds for new discoveries, but if you're just learning about the mission now, here's what you need to know.

"It's the beginning of a new era of exoplanet research."

NASA asked kids to submit their depictions of exoplanets for the satellite's launch.

The spacecraft has spotted almost three-quarters of the alien planets scientists have identified to date.

Loner stars had been tricky to understand, and now scientists can get a better handle on them.
