New molecules around old stars

Herschel image of the Helix Nebula using the SPIRE instrument at wavelengths around 250 micrometres, superimposed on Hubble image of the nebula. The spectrum corresponds to the outer region of the Helix Nebula outlined on the SPIRE image. It identifies the OH+ molecular ion, which is needed for the formation of water. ESA’s Herschel space observatory is the first to detect this molecule in planetary nebulas – the product of dying Sun-like stars. Credit: Hubble image: NASA/ESA/C.R.

2D electronic-vibrational spectroscopy technique provides unprecedented look into photochemical reactions

2-D-EV spectral data tells researchers how photoexcitation of a molecular system affects the coupling of electronic and vibrational degrees of freedom that is essential to understanding how all molecules, molecular systems and nanomaterials function. Credit: Fleming group

Big Bang theory breakthrough under scrutiny

This is an artist's concept of the metric expansion of space, where space (including hypothetical non-observable portions of the universe) is represented at each time by the circular sections.

“Is spacetime a fluid?” Leading physicists query

Summary of the spacetime issues discussed in this article. One can use photons and astronomical objects as test particles to measure spacetime over 22 orders of magnitude in scale, ranging from the cosmic horizon (probing the global topology of and curvature of space - top) to distant supernovae (giving evidence of dark energy) down to galaxies (giving evidence for dark matter), galactic nuclei and binary stellar systems (giving evidence for black holes)
