How the seeds of planets take shape

In theoretical research that could explain everything from planet formation to outflows from stars, to even the settling of volcanic ash, Caltech researchers have discovered a new mechanism to explain how the act of dust ...

VLT clears up dusty mystery

A group of astronomers has been able to follow stardust being made in real time—during the aftermath of a supernova explosion. For the first time they show that these cosmic dust factories make their grains in a two-stage ...

Exocomets may be as common as exoplanets

(Phys.org)—Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system's formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.

Building blocks of life found around young star

(Phys.org)—A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding a young Sun-like star. This is the first time sugar been found in space around ...

New study sheds new light on planet formation

A study published in the July 5 edition of the journal Nature is challenging scientists' understanding of planet formation, suggesting that planets might form much faster than previously thought or, alternatively, that stars ...

Frozen comet had a watery past, scientists find

For the first time, scientists have found convincing evidence for the presence of liquid water in a comet, shattering the current paradigm that comets never get warm enough to melt the ice that makes up the bulk of their ...
