The European Southern Observatory’s 8.2-metre Very Large Telescope captured the most detailed view yet of NGC 2899, a colourful twin-lobed planetary nebular that resembles a vast butterfly surrounded by glowing clouds of high-temperature gas. Reaching temperatures of some 10,000 degrees, the gas is heated by torrents of radiation from the nebula’s parent star, with hot hydrogen creating a reddish halo surrounding the blue of oxygen gas. Located in the southern constellation Vela, the nebula features two central stars. One, near the end of its life, blew off its outer layers but the other star interferes with the outward flow of gas, creating the unusual two-lobed shape. Only 10 percent to 20 percent of planetary nebulae feature such bipolar shapes. This spectacular image was captured by one of the VLT telescopes using the FORS instrument.
This new image from the VLT Survey Telescope (VST) at ESO’s Paranal Observatory in Chile captures a spectacular concentration of galaxies known as the Fornax Cluster, which can be found in the Southern Hemisphere constellation of Fornax (The Furnace). The cluster plays host to a menagerie of galaxies of all shapes and sizes, some of which are hiding secrets.
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.
