A submillimeter survey of protostars

The formation of stars involves the complex interactions of many phenomena, including gravitational collapse, magnetic fields, turbulence, stellar feedback, and cloud rotation. The balance between these effects varies significantly ...

Large water reservoirs at the dawn of stellar birth

(Phys.org)—ESA's Herschel space observatory has discovered enough water vapour to fill Earth's oceans more than 2000 times over, in a gas and dust cloud that is on the verge of collapsing into a new Sun-like star.

Massive Stars Near the Galactic Center

The Central Molecular Zone (CMZ) of our galaxy is a giant complex of molecular gas and dust situated in the innermost 700 light-years of the Milky Way. Although the galaxy is over 100,000 light-years in size, nearly 10% of ...

A new class of dim supernovae

The colossal stellar explosions called supernovae come in many kinds and flavours. Some of them are produced when a massive star reaches the end of its life in a sudden gravitational collapse. Astronomers have just found ...
