Nuclear binding energies of several rare-earth isotopes have been measured for the first time. The experiment provides essential data for understanding how elements heavier than iron are produced in the Cosmos.
Using terahertz spectroscopy, physicists directly measured two spectral lines for one particular molecule for the first time. The discovered frequencies are characteristic of the amide ion, a negatively charged nitrogen molecule.
A series of NASA papers lay out strategies to search for signs of life beyond our solar system. They assume that the detection of atmospheric signatures of a few potentially habitable planets may possibly come before 2030.
Scientists used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: is there really dark matter? Or does Newton's gravitational law need to be modified?
