This weird star nursery shows how the solar system obtained radioactive elements

[ad_1] A turbulent cloud complex, thickened by the turbulence of star formation, provides new clues to the formation of our solar system. Gamma ray analysis from the Ophiuchus star formation complex has given us even more evidence that short-lived radioactive elements in the early solar system were delivered via supernova explosions from nearby stars when … Read more
