Aims: The intracluster light (ICL) is a faint diffuse stellar component of clusters made of stars that are not bound to individual galaxies. We have carried out a large scale study of this component in the nearby Virgo cluster. Methods: The diffuse light is traced using planetary nebulae (PNe). The surveyed areas were observed with a narrow-band

We present 31.5 μm imaging photometry of 11 nearby Seyfert galaxies observed from the Stratospheric Observatory For Infrared Astronomy (SOFIA) using the Faint Object infraRed CAmera for the SOFIA Telescope (FORCAST). We tentatively detect extended 31 μm emission for the first time in our sample. In combination with this new data set, subarcsecond

A planetary nebula has been discovered in the course of the INT/WFC Photometric Hα Survey (IPHAS) of the northern galactic plane. It is located near the galactic anticentre direction. Its small diameter and low Hβ brightness point to an extremely large distance. The ``Shklovskii'' galactocentric distance of DGC = 14-->20 kpc3 makes this nebula one

The authors obtained near infrared images in J, H, and K filters of the H II region N159 in the LMC with the IR Imager on the 1.5 m telescope of CTIO. Some 50 sources are detected in an area of roughly 10 arc min squared. The region seems to be a site of active star formation associated to a large molecular complex and possibly coincides with one
