Sorry, no etymologies found.


  • In order to determine whether the surface of an extrasolar planet would contain water, scientists can look at what is called the protoplanetary disk - a disk of gas and dust surrounding a star during its early stages of development.

  • For those of you scoring at home, "planetesimals" were the first solid objects in our newly minted solar system (also known as the protoplanetary disk).

  • Now researchers have probed whether or not the necessary precursor to planet formation - a so-called "protoplanetary" disk of planet building blocks - could survive in this environment.

  • There are two proposed mechanisms for the formation of gas giants: (a) formation of a rocky/icy core through collisions of dust particles and a subsequent accretion of a gaseous envelope; (b) gravitational instability of the protoplanetary disk.

  • Neither the initial formation of the Sun from a molecular gas cloud, nor the subsequent formation of the planets from the protoplanetary disk was a violent process from the relativistic standpoint: the spacetime remained Newtonian.

  • "We need to see through gas and dust to see star formation and protoplanetary disks" – here's Spitzer.

  • Besides PSR B1257+12, at least one other pulsar planet is known PSR B1620+26 and a protoplanetary disk was revealed around the magnetar 4U 0142+61.

  • Larger organic molecules that coalesced in the dusty disk out of which our planets formed billions of years ago would have been broken apart by the Sun's rays, but calculations by two astronomers at the University of Michigan show that thousands of oceans worth of water present in a protoplanetary disk can shield other molecules from being broken up.
