... News . ... New type of energy hypothesized . Ultralight" energy is proposed as the opposite of dark energy. ... A new type of energy that might have dominated the early universe was suggested and analyzed at the meeting of the American Astronomical Society. Dubbed "ultralight", the energy type is hypothesized to be different from every other type of known energy, including normal matter, radiations such as light, and even the unusual dark energy that is now thought to pervade the universe. ...

Rep ort by the ESA-ESO Working Group on Galactic p opulations, chemistry and dynamics Abstract Between the early 40s, when Baade showed the first evidence for the existence of two distinct stellar populations, and today, with our Galaxy surprising us with new substructures discovered almost on a monthly basis, it is clear that a remarkable progress has been achieved in our understanding of the Galaxy, of its structure and stellar populations, and of its chemical and dynamical signatures. Yet, some questions
