What’s happening in that solar system? 🪐⚠️ The HR 8799 star system hosts four massive planets, each comparable in size to Jupiter, with orbits ranging from several decades to hundreds of years. Scientists are closely monitoring the system to assess its long-term stability. This video presents a sequence of 10 images of HR 8799 taken with the Keck Telescope over 12 years. Created by Jason Wang, with data processing by William Thompson and Christian Marois, and observational coordination by Quinn

HR 8799 es una joven estrella, situada a unos 130 años luz de la Tierra en la constelación de Pegaso. Con aproximadamente 30 millones de años de edad, es notable por albergar el primer sistema planetario múltiple observado directamente mediante imágenes astronómicas. #astronomia #cosmos #universo #estrellas #NASA | Astro Chile

The star HR 8799, located 129 light-years away in the constellation Pegasus, has four gas giant planets more massive than Jupiter orbiting it, which were among the first exoplanets observed directly in 2008.
