The JuMBOs have much wider separations than other populations of substellar binaries, and their existence challenges conventional...

... cloud, recently discovered in the far ultraviolet via H₂ fluorescence, is one of the nearest known dark molecular clouds to the Sun, with a distance spanning from ∼94–136 pc. However, with a mass (∼5.5 × 10³ M_⊙) just under 40 per cent that of star forming clouds like...

... stellar objects (YSOs) in G328.24−0.55 star forming region. The dust continuum image reveals 5 protostellar objects (MM1a, MM1b, MM1c, MM2 and MM3), with MM1a dominating the region. The dust continuum peaks do not coincide with the strongest radio continuum peak previously detected in the region...

The distribution of glitch sizes in individual pulsars, the power-law being the most argued for, is shrouded in uncertainty due...
