LIVERMORE, Calif.– The oxygen and magnesium content of some of the oldest objects in the universe are giving clues to the lifetime of the solar nebula, the mass of dust and gas that eventually led to ...

The story of our solar system's origin is pretty well known. It goes like this: the sun began as a protostar in its "solar nebula" over 4.5 billion years ago. Over the course of several million years, ...

Hard and fast details about our solar system’s beginnings are extraordinarily difficult to come by. But a research team using new measurements of pristine magnetic fields within two extremely rare ...

Members of the NAI UCLA team led by Ed Young are using high-precision analysis of tiny grains in meteorites to probe the earliest history of the solar nebula. The age of the solar system is set at ...

And the earth was without form and void, and darkness was upon the face of the deep. Sometimes, if the night is dark and clear enough, you can look up and see the Milky Way in its arc across the sky.

The solar nebula sustained a strong magnetic field that may have aided planetesimal accretion and imparted the chemical remanent magnetization (CRM) observed in some carbonaceous chondrite meteorites.

Artist’s impression of the solar nebula. Astronomers study the leftovers of solar system formation that once existed in this cloud to understand conditions at that time. They want to know how long it ...

Astronomers have discovered a dense stellar nursery packed with infant stars in a vast "cosmic ink blot." The team made the discovery using one of the most powerful digital cameras in the world: the ...
