The APEX observations, made with its LABOCA camera, are shown here in orange tones, combined with a visible light image from the Curtis Schmidt telescope at the Cerro Tololo Interamerican Observatory. The result is a dramatic wide-field picture that provides a spectacular view of CarinaтАЩs star formation sites. The nebula contains stars equivalent to over 25,000 Suns, and the total mass of gas and dust clouds is that of about 140,000 Suns. Credit: ESO/APEX/T. Preibisch et al. ...

... As we have seen, evolutionary considerations based on our current understanding of massive binary systems lead to the conclusion that BH+PSR binaries must constitute a rather numerous subclass of all binary PSR ( 1 per 1000 isolated pulsars; Lipunov et al. , 1994b[ 124 ]). It seemed a priori that the binary radio pulsar PSR B0042-73   in the SMC (Kaspi et al., 1994[ 81 ]) could belong to one of these two classes. ... This means that such binary pulsars should be discovered in the near future. ...

... In one situation, we can use light from quasars to probe the material between us and them because that light may pass through one or more galaxies or gas clouds on its way to us. The gas inside the galaxies or the intergalactic clouds acts then as a filter, absorbing selected wavelengths from the quasar light. ... Light from a quasar must pass through clouds of gas and even faint galaxies -- each leaving its imprint on the light -- before we receive it here on Earth. ... Gravitational lensing . ...
