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.

Protostars In Orion Nebula Doomed By Larger Stars

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found that some protostars in the Orion Nebula are doomed from the beginning.

Astronomers Discover Drastic Chemical Change In The Birth Of A Planetary System

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.

Fluffy Disk Baby Star

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.

Zombie-Like Vortex Gives Final Push To Birth New Star

For years, most astronomers have agreed on the basic steps that lead to star formation, except one – how a cloud of swirling gas can slow down enough to concentrate into something capable of nuclear fusion.

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...

Accretion Disk -- An accretion disk is a structure formed by material falling into a gravitational source. Conservation of angular momentum requires that, as a large cloud of material collapses inward, any small rotation it may have will increase. Centrifugal force causes the rotating cloud to collapse into a disk, and tidal effects will tend to align this disk's rotation with the rotation of the gravitational source in the center. Friction between the particles of the disk generates heat...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
