The bright nebular complex NGC 6334 contains some of the most active sites of massive star formation known in our Galaxy. It is located at a distance from the Sun of 1.62 kpc and has a total mass of a few 105M . The physical characteristics of the active spots range widely, from well ...
At the distance of NGC 6334 I(N), the 6 cm flux densities of these objects would be 0.04–0.9 mJy, a range that includes both VLA2 and H2O-C4. It is interesting to note that HW 8 and HW 9 are both X-ray sources with HW 8 postulated to be a pre-main sequence star (due to ...

We measured the White Dwarfs cooling sequence in NGC6752 with the Hubble Space Telescope and, comparing it to a fiducial cooling sequence of field WDs we derive a distance modulus (m-M)0=13.05 ±0.10, and an age of about 15 Gyr (±1.5 Gyr)....
