Latest Nebular hypothesis Stories
The first images captured with the Atacama Large Millimeter/submillimeter Array's new high-resolution capabilities have given researchers their best look ever at the process of planet formation around an infant star.
Scientists using the Atacama Large Millimeter/submillimeter Array in Chile have observed a very exciting phenomenon — the exchange of dust and gas in a multiple-star system.
Using the European Southern Observatory's Atacama Large Millimeter/submillimeter Array, astronomers have observed what seems to be windy weather surrounding a T Tauri star—considered to be an infant analog of our own Sun.
Researchers set out to study the protoplanetary disk around a star known as HD 100546, and as sometimes happens in scientific inquiry, it was by "chance" that they stumbled upon the formation of the planet orbiting this star.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have found wildly misaligned planet-forming gas disks around the two young stars in the binary system HK Tauri.
An international team of astronomers has revealed a complicated outflow structure in the binary UY Aur (Aurigae).
A team of Japanese astronomers has located evidence of a giant planetary system forming around a young star named HD142527, and their discovery that could change existing theories on how planets form and provide new insights into the formation of a vast array of different planetary systems.
In an effort to search out other worlds, astronomers from the SEEDS project have turned their attention to a somewhat unusual source - a young star known as Ry Tau (Tauri) located some 460 light-years from Earth.
The Subaru Telescope has helped astronomers capture the first vivid infrared image of a distant planet forming from a young star.
In the second installment of our new series, Dr. Eric Mamajek discusses how planets form and the search for planets outside of our solar system.
Cosmogony -- Cosmogony is the study of the origins of celestial objects. It is most commonly used to refer to the study of the origin of the solar system. Currently, the most widely accepted theory is that the solar system was formed roughly 5 billion years ago with the collapse of a nebula of gas and dust, likely caused by shock waves generated by a nearby supernova. The solar system would have formed as a member of a star cluster, now long-since dispersed throughout the Milky Way over...
Solar Nebula -- In astronomy, the solar nebula is the gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation, gradually pulled together by its own gravitational force and flattened into a spinning disk, gave birth to the Sun and planets. A similar model, but with the planets being formed before the Sun, was proposed...
