2025年1月30日 · View interactive 3D models, read descriptions and vital statistics, and filter by exoplanet type, or by the method used to discover it, or the spacecraft, observatory, or other facility that found it.

NASA’s Exoplanet Exploration Program, the search for planets and life beyond our solar system.

2018年4月12日 · The worlds orbiting other stars are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze.

A timeline of discovery: NASA's early work searching for planets beyond our solar system through notable exoplanet discoveries.

Welcome to NASA's Eyes, a way for you to learn about your home planet, our solar system, the universe beyond and the spacecraft exploring them.

2016年11月18日 · The NASA Exoplanet Exploration Program (ExEP) science and missions represent an undertaking of unprecedented scope and ambition, promising insight into humankind's most timeless questions: What kinds of planetary systems orbit other stars in …

When you participate in Exoplanet Watch, you can learn how to observe transiting exoplanets. Using small ground-based telescopes with tracking mounts and cameras, you can take a series of 50-100 pictures of a star as an exoplanet transits or crosses in front of it.

2024年10月25日 · LTT 1445 A c is a super Earth exoplanet that orbits an M-type star. Its mass is 1.54 Earths, it takes 3.1 days to complete one orbit of its star, and is 0.02661 AU from its star. Its discovery was announced in 2022.

2023年12月12日 · NASA’s James Webb Space Telescope is already using onboard spectrographs to tease out the components of exoplanet atmospheres. In the years ahead, the agency’s Nancy Grace Roman Space Telescope, to be launched by May 2027, is designed to study the cloudy atmospheres of mature, Jupiter-sized exoplanets.

Astronomers have now confirmed more than 5,000 exoplanets – planets beyond our solar system. But it’s just a fraction of the likely hundreds of billions in our Milky Way galaxy. The cones of exoplanet discovery radiate out from planet Earth, like spokes on a wheel.
