The Seagull Nebula, on the border between Canis Major and Monoceros some 3,700 light years away, resembles a great bird in flight with a wingspan stretching 100 light years from tip to tip. That description is an example of pareidolia, the human tendency to find familiar patterns in random or ambiguous shapes. In this case, the “seagull” is a vast collection of clouds made up of dust, hydrogen, helium and trace amounts of heavier elements, a stellar nursery providing the raw materials for new generations of stars. This stunning image from the European Southern Observatory’s VLT Survey Telescope shows the Seagull Nebula in remarkable detail, from ionised gas and dark dust lanes in Sharpless 2-296, the “wings” of the seagull, to the compact cloud forming its head where a piercing eye – a 20-solar-mass extremely luminous star – brilliantly shines.
The Sculptor Dwarf Galaxy: a shy galactic neighbour
The Sculptor Dwarf Galaxy, pictured in this new image from ESO’s La Silla Observatory, is a close neighbour of the Milky Way. This galaxy is much smaller and older than ours, making it a valuable subject for studying both star and galaxy formation in the early universe. However, due to its faintness, studying this object is no easy task.
‘Pillars of destruction’ in the Carina Nebula
Spectacular new observations of vast pillar-like structures within the Carina Nebula have been made using the MUSE instrument on ESO’s Very Large Telescope. The different pillars analysed by an international team seem to be pillars of destruction — in contrast to the name of the iconic Pillars of Creation in the Eagle Nebula, which are of similar nature.
VST captures 615-megapixel image of open cluster Messier 18
Messier 18 is the small smattering of bright blue stars upper left of centre in this small-scale version of the original mammoth 30,577 x 20,108 pixel ESO image captured by the OmegaCAM camera attached to the VLT Survey Telescope (VST), located at the European Southern Observatory’s Paranal Observatory in Chile.
