Due to their extreme helium abundance, the multiple stellar populations of the globular cluster NGC 2808 have been widely investigated from a photometric, spectroscopic, and kinematic perspective. The most striking feature of the colour-magnitude diagram of NGC 2808 is the triple main sequence (MS), with the red MS corresponding to a stellar

Scientific literacy in our society has entered a period of serious decline. Contrary to our perception, the interest of lay people for the sciences has not grown in parallel with the advances that science has brought to society. Advanced communitites are starting to feel the shortage of bright scientists. In what follows I will try to examine the

The Extreme Universe Space Observatory on the Japanese Experiment Module (JEM-EUSO) on board the International Space Station (ISS) is the first space-based mission worldwide in the field of Ultra High-Energy Cosmic Rays (UHECR). For UHECR experiments, the atmosphere is not only the showering calorimeter for the primary cosmic rays, it is an

Most young, ultracool substellar objects with spectral types later than M9 show very red mid-infrared colors up to 24~micron, significantly redder than expected for their optical and near-infrared spectral classifications. These objects have estimated ages and masses in the intervals 20-300 Myr and 12-35 times the mass of Jupiter, respectively

The imager on board INTEGRAL (IBIS) presently provides the most detailed sky images ever obtained at energies above 30 keV. The telescope is based on a coded aperture imaging system which allows to obtain sky images in a large field of view (29deg x 29deg) with an angular resolution of 12'. The System Point Spread Function of the telescope and its

We present 12CO J = 3→2 maps of NGC 2976 and NGC 3351 obtained with the James Clerk Maxwell Telescope (JCMT), both early targets of the JCMT Nearby Galaxy Legacy Survey (NGLS). We combine the present observations with 12CO J = 1→0 data and find that the computed 12CO J = 3→2 to 12CO J = 1→0 line ratio (R31) agrees with values measured in other NGLS
