Computer models have shown that the early solar system was a tumultuous billiards table, with dozens or even hundreds
of planetary building blocks the size of Earth bouncing around.
Thinking small has enabled an international team of scientists to gain new insight into the evolution
of planetary building blocks in the early solar system.

The discs around these stars contain gas, dust, and planetesimals — the
building blocks of planets and the progenitors
of planetary systems.
Then, the team used a computer program to test different compositions
of basic
planetary building blocks to determine which makeups would yield planets with those densities.
Horst Uwe Keller, a
planetary scientist at the Technical University
of Braunschweig in Germany, and the former principal investigator for the Rosetta camera, says that it is too early to say whether the dinosaur eggs are truly fundamental
building blocks.
One ERS program will stare into the hearts
of neighboring nascent star systems to watch ices, organic molecules and other
planetary building blocks dance around coalescing suns.
However, another
planetary building block does appear to linger: the gaseous parts
of the disks, perhaps fostering additional growth
of gas - giant planets like Jupiter for millions
of years.
In the Solar System, the asteroid belt contains the leftover
building blocks for the terrestrial planets Mercury, Venus, Earth, and Mars, so
planetary scientists study the asteroids to gain a better understanding
of how rocky, and potentially habitable planets are formed.
In research published this week in Astrophysical Journal Letters, Dr Zoe Leinhardt and colleagues from Bristol's School
of Physics have completed computer simulations
of the early stages
of planet formation around the binary stars using a sophisticated model that calculates the effect
of gravity and physical collisions on and between one million
planetary building blocks.
We will carry out a series
of numerical investigations to understand how organics and volatiles are incorporated into
planetary building blocks and then trace the dynamical evolution
of these
building blocks throughout the period
of planetary assembly.

planetary building blocks,» states Maria Zuber, Professor
of Geophysics and MIT's vice president for research.

of the first
building blocks of the Solar System and may shed light on
planetary accretion.
In a fascinating set
of projects we will look at the smallest scales and back in time, probing the mineralogy and composition
of micron - sized grains in ancient meteorites using the most sophisticated microscopic techniques, to explore the history
of volatiles and organics in
planetary building blocks at the time when the Solar System was young.
«Here we have a rare opportunity to study a phenomenon that plays out over many decades and provides a window into the types
of environments around stars that could represent
planetary building blocks at the very end
of a star system's life.»
ALMA will study the
building blocks of stars,
planetary systems, galaxies and life itself.
Eventually, those materials are recycled, providing the
building blocks for a new generation
of stars and accompanying
planetary systems.
