New observations using the Atacama Large Millimeter/submillimeter Array (ALMA) have distinguished the sites of star formation and a possible site of star death from the surrounding nebula in a galaxy 13.2 billion light-years ...

Imagine the explosive disturbance caused by a jet going supersonic. A similar shock wave occurs when subatomic particles known as "solar wind" flow from the sun and strike the Earth's magnetic field. Now, scientists have ...

A trio of astronomers from Armagh Observatory & Planetarium and Centro de Astrobiología (CAB), CSIC-INTA has found that a white dwarf that was recently projected to make its way toward our solar system will not do so.
Astronomers have mapped 39 interstellar clouds where high-mass stars are expected to form. This large data set shows that the accepted model of low-mass star formation needs to be expanded to explain the formation of high-mass ...

,We all used to think there were nine planets. But in 2006, the solar system was left with only eight planets, when Pluto was no longer classified as such. But is it still possible there is a planet out there beyond Neptune—possibly ...
