Key Concepts

What is an exoplanet?

An exoplanet is a planet that orbits a star outside our solar system. Over 5,700 exoplanets have been confirmed as of 2026, with thousands more candidates awaiting verification. They range from scorching hot Jupiters to potentially habitable rocky worlds. NASA's TESS and the James Webb Space Telescope are the primary tools for finding and studying them.

How does the James Webb Space Telescope work?

JWST is an infrared space telescope with a 6.5-meter gold-coated mirror (compared to Hubble's 2.4m). It orbits the Sun at the L2 Lagrange point, 1.5 million km from Earth, where its sunshield keeps instruments at -233C. By observing in infrared, Webb can see through cosmic dust, study the atmospheres of exoplanets, and detect light from the earliest galaxies formed after the Big Bang.

What is a light-year?

A light-year is the distance light travels in one year — about 9.46 trillion kilometers (5.88 trillion miles). It's used because space distances are so vast that kilometers become meaningless. For scale: the nearest star (Proxima Centauri) is 4.24 light-years away. The Milky Way galaxy is about 100,000 light-years across. The observable universe extends 46 billion light-years in every direction.

What's the difference between NASA, ESA, and SpaceX?

NASA (US) and ESA (Europe) are government space agencies funded by taxpayers — they do science, exploration, and Earth observation. SpaceX is a private company founded by Elon Musk that builds rockets and spacecraft. SpaceX focuses on making space access cheaper (reusable Falcon 9, Starship), while NASA and ESA define scientific missions. They often work together — SpaceX launches NASA astronauts to the ISS.

How can I see the ISS?

The International Space Station is the third brightest object in the night sky (after the Sun and Moon). It looks like a fast-moving bright star crossing the sky in 3-5 minutes. Use NASA's Spot The Station website or the Heavens-Above app to get exact times for your location. Best sightings happen just after sunset or before sunrise when the station catches sunlight against a dark sky.
