Early life was radically different than today

All modern life shares a robust, hardy, efficient system of intertwined chemicals that propagate themselves. This system must have emerged from a simpler, less efficient, more delicate one. But what was that system, and why ...

Webb finds icy complex organic molecules around protostars

In the quest to understand how and where life might arise in the galaxy, astronomers search for its building blocks. Complex Organic Molecules (COMs) are some of those blocks, and they include things like formaldehyde and ...

ALMA observation of young star reveals details of dust grains

One of the primary goals of the Atacama Large Millimeter/submillimeter Array (ALMA) is to study the formation and evolution of planetary systems. Young stars are often surrounded by a disk of gas and dust, out of which planets ...

Webb follows neon signs toward new thinking on planet formation

Scientists are following neon signs in a search for clues to one planetary system's future and the past of another—our own solar system. Following up on a peculiar reading by NASA's previous infrared flagship observatory, ...

Webb findings support long-proposed process of planet formation

Scientists using James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical process involving the drifting ...

JWST looks at the debris disk around a white dwarf

Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around ...
