Simulations Reveal How Craters Could Reveal the Interior of Asteroid Psyche Asteroid 16 Psyche, a metal-rich object located in the main asteroid belt between Mars and Jupiter, has puzzled scientists for over two centuries. At roughly 140 miles in diameter, Psyche is the largest known metal asteroid and may hold clues to the early formation of planets in our Solar System. Researchers from the University of Arizona have simulated the formation of a massive crater near Psyche’s north pole to better understand the asteroid's internal structure. Their simulations examined two scenarios: one where Psyche has a layered interior with a metallic core and thin rocky mantle, possibly resulting from a catastrophic collision, and another where it consists of a mixed metal-and-rock composition formed by repeated impacts. A key finding is the role of porosity, or the internal empty spaces, in shaping crater formation and debris distribution. Higher porosity allows the asteroid to absorb impact energy, producing deeper craters with less scattered debris. These simulations provide testable predictions for NASA's Psyche spacecraft, scheduled to arrive in 2029, which will measure surface composition, gravity, and magnetic fields. By combining these models with spacecraft data, scientists hope to determine whether Psyche is the exposed core of a former planet or a chaotic assembly of metal and rock, offering insights into violent processes that shaped early planetary evolution.

An adolescent growth spurt in young stars helps giant planets form Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the stars rotate, gas and dust accumulates in a rotating disk around the star called a protoplanetary disk. As the name makes clear, this is where planets form by accreting material from the disk.

Trying to find baby planets swaddled in dust When it comes to finding baby, still-forming planets around young stars, the Atacama Large Millimeter/submillimeter Array (ALMA) observatory is astronomers' most adept tool. ALMA has delivered many images of the protoplanetary disks around young stars, with gaps and rings carved in them by young planets. In new research, a team of researchers used ALMA to image 16 disks around young class 0/1 protostars and found that planets may start forming sooner than previously thought.
