The new results from SPHERE, along with data from
other telescopes such as ALMA, are revolutionising astronomers» understanding of the environments around young stars and the complex mechanisms of
planetary formation.
It may seem like a trivial distinction for something billions of years old, but it could make a difference when pinning down the conditions that led to the solar system's
formation, says Bouvier, and those needed for
other life - friendly
planetary systems to form.
The discovery of strangely ordered
planetary systems around
other stars showed that the
formation process can not be so tidy after all.
His team found that by tuning the model so that the pebble
formation process takes a bit longer, there is more time for the large
planetary embryos to interact with each
other gravitationally.
Its dense iron core takes up 42 per cent of its volume, its orbit is less circular than that of the
other planets, and current
planetary formation models predict Mercury should be closer to the sun and bigger, so we know we're missing something.
For
planetary scientists like Jackson, being able to observe objects like these may yield important clues about how planet
formation works in
other star systems.
The new study suggests that the «hot Jupiter» WASP - 18b, a massive planet that orbits very close to its host star, has an unusual composition, and the
formation of this world might have been quite different from that of Jupiter as well as gas giants in
other planetary systems.
The improved understanding gives researchers new insight about the basic properties of silica and
other materials, and could ultimately lead to improved models of
planetary formation and composition and new approaches for designing future materials with improved functionality, such as strength.
Coming hot off the heels of discoveries made by
other observatories, including NASA's Kepler and CoRot (the Convection, Rotation, and
Planetary Transits mission, led by France's CNES with contributions from the ESA), this spacecraft is intended to build significantly on our knowledge of the universe, the Solar System, and the
formation of life in general.

Planetary Science and Astronomy class.
Observations of the planets, satellites, and small bodies in the Solar system provide indispensable information about planet
formation and evolution processes that remain unattainable for
other planetary systems.
This definition is based in modern theories of
planetary formation, in which
planetary embryos initially clear their orbital neighborhood of
other smaller objects.

They seek answers to questions about the structure of the universe, the
formation of our solar system and
other planetary systems, the behavior and transformation of matter when subjected to extreme conditions, the origin of life, the function of genes, and the development of organisms from single - celled egg to adult.
