Search for Life Beyond the Solar System

Search for Life Beyond the Solar System

Motivated by the rapidly increasing number of known Earth-sized planets, the increasing range of extreme conditions in which life on Earth can persist, and the progress toward a technology that will ultimately enable the search for life on exoplanets, the Vatican Observatory and the Steward Observatory announce a major conference entitled The Search for Life Beyond the Solar System: Exoplanets,…

Science with the Hubble Space Telescope

Science with the Hubble Space Telescope

This conference is designed to highlight the scientific breakthroughs made by the Hubble Space Telescope in its two decade long life. We have three specific goals for this meeting: To share the latest results from Hubble across the broad canvas of astronomy, To inspire the community of Hubble users to think how Hubble’s successor—the James…

Possible evidence for dark matter particles

Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the Universe, is crucial to the formation of galaxies, stars and even life but has so far eluded direct observation. At a recent UCLA symposium attended by 190 scientists from around the world, physicists presented several analyses that participants…

The potential of string theory as an elegant unified description of physics

Nell'Agosto del 1984 due fisici arrivarono ad elaborare una formula che aprì una nuova finestra verso la comprensione della teoria delle stringhe. Lo scorso mese di Dicembre, Michael Green dell'Università di Cambridge e John Schwarz del California Institute of Technology sono stati insigniti del Fundamental Physics Prize 2014, uno dei premi della serie "Breakthrough Prizes" che…

Gas and stars in galaxies: A multi-wavelength 3D perspective

Gas and stars in galaxies: A multi-wavelength 3D perspective

In 2008 ESO hosted the first conference on extragalactic 3D multi-wavelength astronomy. This very successful workshop attracted more than 150 astronomers with expertise ranging from the radio to the optical wavelengths. In the intervening five-year period, 3D spectroscopic techniques have greatly extended our understanding of the key subjects addressed in this workshop. The kinematics, mass assembly and…

Using the Universe as 'tool' to detect gravitons

La gravità è l'unica tra le quattro forze fondamentali per la quale gli scienziati non hanno ancora rivelato la sua unità fondamentale. Infatti, secondo il modello standard delle particelle elementari si ritiene che l'interazione gravitazionale venga trasmessa attraverso il gravitone, allo stesso modo con cui l'interazione elettromagnetica viene trasmessa dai fotoni. Oggi, nonostante esistano delle…
