    The asteroid belt between Mars and Jupiter preserves the processes of planetary formation, frozen in time. Vesta, the second largest asteroid in this belt, provides an outstanding opportunity for scientists to investigate the origin and formation of planets. In particular, Vesta has kept its crust, mantle and metallic core, much like Earth. Careful mapping of Vesta by NASA’s Dawn mission showed that the crust at the south pole of Vesta is unusually thick.

    In a paper just published in Nature Geoscience, Dr. Yi-Jen Lai of the Macquarie University Planetary Research Centre and Macquarie GeoAnalytical and her colleagues propose a new evolutionary history of Vesta involving a giant impact...

    Planet Formation Starts Before Star Reaches Maturity

    MC1A is a still developing star in the constellation Taurus. Red are areas with many dust particles. Green and blue are two types of carbon monoxide. The absence of green / blue carbon monoxide in the inner part indicates that dust particles in the young protoplanetary disk have grown from less than a thousandth of a millimeter to a millimeter.

    A European team of astronomers has discovered that dust particles around a star already coagulate before the star is fully grown. Dust particle growth is the first step in the formation of planets. The researchers from the Netherlands, Sweden and Denmark publish their findings in Nature Astronomy.

    In recent years, astronomers have discovered numerous planetary systems around other stars...

    Gigantic Jupiter-type Planet reveals Insights into how Planets Evolve

    Astrophysicists get rare peek at a baby solar system 300 light-years away. An enormous young planet ~300 light-years from Earth has given astrophysicists a rare glimpse into planetary evolution. The planet, known as HD 106906b, was discovered in 2014 by a team of scientists from the U.S., the Netherlands and Italy...

    ALMA measures Size of Seeds of Planets

    Dust disk around the young star HD 142527 observed with ALMA.

    Researchers have for the first time, achieved a precise size measurement of small dust particles around a young star through radio-wave polarization. ALMA’s high sensitivity for detecting polarized radio waves made possible this important step in tracing the formation of planets around young stars. Astronomers have believed that planets are formed from gas and dust particles, although the details of the process have been veiled. One of the major enigmas is how dust particles as small as 1 micrometer aggregate to form a rocky planet with a diameter of 10,000 km. Difficulty in measuring the size of dust particles has prevented astronomers from tracing the process of dust growth.

    Akimasa Kataoka and his collaborators have theoretic...
