«You build bigger, you go fainter, you go deeper, and you'll have a shot at a major discovery,» explains Pudritz, «So building these larger machines will no doubt allow us to study the birth of the first galaxies and
even planet formation around distant stars.

We will also apply for more observation time on the ALMA telescope to study the
planet - forming discs in even higher resolution to get more detailed information about their chemical composition,» says Jes Jørgensen, associate professor in the research group Astrophysics and Planetary Science at the Niels Bohr Institute and Centre for Star and Planet Formation, University of Copen

Two recent studies show that the
formation of
planets may leave detectable chemical signatures in their host stars, a finding that could help scientists zero in on planetary systems
even more quickly and speed the search for worlds similar to Earth.
«
Even using just the first 16 of its 66 antennas, ALMA will already surpass the capabilities of all existing telescopes of its kind, and will provide new insights into star
formation as well as the origins of galaxies and
planets,» says Paola Andreani, manager of the European ALMA Regional Centre at the European Southern Observatory.
These doughnut - shaped objects might
even explain the
formation of other terrestrial
planets like Mars, Venus, and many more outside our solar system.
The
formation of binary minor
planets, tumbling action, and period change are most likely due to the YORP effect, which is a thermal process where absorbed sunlight, re-radiated as heat, can affect the minor
planet's rotation period and
even spin axis orientation.
It was believed that the
formation of two or more stars would hardly leave enough mass remaining to cohere into
planets, and that
even if those
planets were created, the gravitational pull of a close second star would expel them from their orbits — either by shoving them out of the system or pulling them to fall into one of the stars.
This result, that systems with multiple transiting
planets are less likely to include a transiting giant
planet, suggests that close - in giant
planets tend to disrupt the orbital inclinations of small
planets in flat systems, or maybe
even to prevent the
formation of such systems in the first place.
Some astronomers have speculated that inner Oort Cloud objects could
even be extra-Solar
planets gravitationally captured from neighboring stars during the
formation of the Solar System.
While we have ample evidence of
planet formation and have
even caught it in the act, as yet we have no firm detections of moon
formation.
By the predominant theory at the time that I knew, we had a single predecessor star, Population II or perhaps
even III, and possibly some additional stuff from the interstellar medium got mixed in during the
formation of the current star and
planets.
