UrduThe earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory found that those variations are not caused by irradiation from the sun but are produced by condensation and evaporation reactions in the early solar system.

Gigantic Cavity in Space Sheds New Light on How Stars Form
Astronomers have discovered a humongous cavity in space while mapping interstellar dust. The sphere-shaped phenomenon may explain how supernovae lead to star formation.
Sculpted by starlight: A meteorite witness to the solar system’s birth
Researchers examine a 4.6 billion- year-old rock to better understand the solar system’s beginning, and a modern mystery.
IMAGE RELEASE: New Look at a Bright Stellar Nursery
New, high-resolution VLA images of a giant molecular cloud where new stars are being born show changes since a set of observations made more than two decades ago. Tracking changes in this region over time can reveal new details about the process of star formation and the interactions of outflows from young stars.
