🪐 Suspended in the asteroid belt, the metallic world Psyche is thought to be the exposed nickel-iron core of an ancient protoplanet, stripped of its outer layers by violent collisions. Unlike rocky or icy asteroids, Psyche’s composition gives it unusual magnetic properties and a surface shimmering with metal-rich regolith. ✨

🪐 Orbiting Jupiter, the tiny moon Amalthea is so porous and irregularly shaped that scientists believe it’s more akin to a loosely packed pile of rubble than a solid body. Despite being only about 250 kilometers across, Amalthea glows with a striking reddish color, likely stained by sulfur dust ejected from the neighboring volcanic moon Io. ✨

🪐 In the star-forming region of the Orion Nebula, astronomers have identified "proplyds"—dense disks of gas and dust swirling around newborn stars. These proplyds are being sculpted by fierce ultraviolet radiation from nearby massive stars, their bright comet-like tails pointing away from blazing giants such as Theta1 Orionis C. ✨

🪐 In the constellation Ophiuchus, the asteroid 101955 Bennu harbors boulders on its surface that are actually fragments from a much larger parent asteroid, dislodged by ancient cosmic impacts. Analysis of samples returned by NASA’s OSIRIS-REx mission revealed minerals that interacted with liquid water billions of years ago, revealing Bennu as a time capsule from the dawn of the solar system. ✨

🪐 Hidden over 430 light-years away in the constellation Ophiuchus, the protoplanetary disk around the young star AS 209 is riddled with striking gaps and rings thought to be carved by newly forming planets. ALMA observations revealed the disk’s outermost gap may be created by a planet similar in mass to Neptune, astonishing astronomers because it would be forming over 200 astronomical units from its star—far beyond the realms where planets are usually born. ✨
