We present the discovery of a new planetary nebula from the IPHAS survey. The remarkable morphology of its inner regions, which display a bright knotty ring surrounded by high excitation gas, led to the object's nickname, the ``Necklace nebula''. The finding of a binary central star with an orbital period of 1.16 days makes it a new clear example

The IACOB spectroscopic survey of Galactic OB stars is an ambitious observational project aimed at compiling a large, homogeneous, high-resolution database of optical spectra of massive stars observable from the Northern hemisphere. The quantitative spectroscopic analysis of this database, complemented by the invaluable information provided by Gaia

We suggest that experiments based on Josephson junctions, SQUIDS, and coupled Josephson qubits may be used to construct a resonant environment for dark matter axions. We propose experimental setups in which axionic interaction strengths in a Josephson junction environment can be tested, similar in nature to recent experiments that test for quantum

New deep broad- and narrow-band (JHK and Br Gamma at 2.17 μm and H2 at 2.12 μm) images of the mid-infrared source G287.47-0.54 (Tr14-N4) are presented and analysed along with archive 3.6 to 8 μm Spitzer images. We demonstrate the presence of a compact (0.3 pc) embedded infrared cluster with at least 72 young members. The age of the cluster is
