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.

Stellar shockwaves shaped our solar system

The early years of our Solar System were a turbulent time, and questions remain about its development. Dr Tagir Abdylmyanov, Associate Professor from Kazan State Power Engineering University, has been researching shockwaves ...

HP, Dell: PC makers in desperate need of a reboot

Hewlett-Packard Co. used to be known as a place where innovative thinkers flocked to work on great ideas that opened new frontiers in technology. These days, HP is looking behind the times.

The spectral energy distribution of protostars

(Phys.org) -- Stars form when gravitational forces coalesce the gas and dust in interstellar clouds until the material forms clumps dense enough to become stars. Precisely how this happens, however, is still very uncertain. ...

Fingering the culprit that polluted the Solar System

(Phys.org) -- For decades it has been thought that a shock wave from a supernova explosion triggered the formation of our Solar System. According to this theory, the shock wave also injected material from the exploding star ...

Pollution teams with thunderclouds to warm atmosphere

Pollution is warming the atmosphere through summer thunderstorm clouds, according to a computational study published May 10 in Geophysical Research Letters. How much the warming effect of these clouds offsets the cooling ...

A planetary system from the early Universe

A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion years ago. The system consists of the star HIP 11952 and two planets, ...
