♦ Astronomers have discovered a planetary system orbiting a youthful star YSES-1 located 300 light-years away, using the James Webb Space Telescope (JWST).  

♦ The system's two planets, YSES-1 b and YSES-1 c, are packed with coarse, rough, and frankly irritating silica material.

♦ Astronomers say this discovery around a star that is just 16.7 million years old could hint at how the planets and moons of our 4.6 billion-year-old solar system took shape.

♦ As both planets are gas giants, they could offer astronomers an opportunity to study the real-time evolution of planets like Jupiter and Saturn.

♦ One of these extrasolar planets, or "exoplanets," YSES-1 c, has a mass around 14 times the mass of Jupiter. On YSES-1 c, this silica matter is located in clouds in its atmosphere, which gives it a reddish hue and creates sandy rains that fall inward towards its core.
