Hubble Observes Star's Superheated Planet-Forming Disk

The Hubble Space Telescope has revealed that the star FU Orionis, located 1,360 light-years from Earth, has a planet-forming disk that reaches temperatures three times hotter than the Sun's surface. This extreme heat is caused by the disk's rapid rotation and collision with the star's surface, creating a shockwave. Such conditions make it unlikely for Earth-like planets to form close to the star, as they would be either consumed or destroyed by radiation. The findings were published in The Astrophysical Journal Letters.

First-ever telescope capture of aftermath and afterglow of violent planetary collision

Astronomers have captured the aftermath of a massive planetary collision for the first time, observing two ice giant exoplanets colliding around a Sun-like star. The collision resulted in an intense blaze of light and the release of enormous dust plumes. The event was initially detected through the star's infrared brightness, which increased before a visible dimming. The debris cloud from the collision is expected to disperse along the orbit, potentially forming moons around the emergent planet. This rare observation provides valuable insights into the dynamics of exoplanet collisions and the formation of celestial bodies.
