Exoplanets

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []

NASA''s Webb Detects Carbon Dioxide in Exoplanet Atmosphere

NASA''s James Webb Space Telescope has captured the first clear evidence for carbon dioxide in the atmosphere of a planet outside the solar system. This observation of a gas giant planet orbiting a Sun-like star 700 light-years away provides important insights into the composition and formation of the planet. The finding, accepted for publication in Nature, offers

A Whole New Jupiter: First Science Results from NASA''s Juno

Early science results from NASA''s Juno mission to Jupiter portray the largest planet in our solar system as a complex, gigantic, turbulent world, with Earth-sized polar cyclones, plunging storm systems that travel deep into the heart of the gas giant, and a mammoth, lumpy magnetic field that may indicate it was generated closer to the planet''s surface than previously

Largest Batch of Earth-size Habitable Zone Planets Found

TRAPPIST-1: Largest Batch of Earth-sized Exoplanets The most studied planetary system, aside from our own solar system, lies about 40 light-years away. We''ve looked at the seven rocky exoplanets orbiting the TRAPPIST-1 star with ground and space telescopes like Spitzer, Kepler, Hubble, and, now, the James Webb Space Telescope. In March 2023, the first science []

Outer Solar System More Populated than We Thought

Observations of the outer Solar System with the Subaru Telescope have discovered new bodies where none were expected. The new objects are likely members of a much larger population waiting to be discovered. This discovery has profound implications for our understanding of the structure and history of the Solar System. First and foremost, it suggests

Hubble Science Themes

Overview Hubble''s three decades of exploration have forever changed our understanding of the universe. Its discoveries have won the Nobel Prize, proven Einstein''s theories, detected planets beyond our solar system, enlightened our understanding of dark matter and dark energy, and prompted questions that go beyond those we first sought to answer with it. Hubble is []
