PIX4569048: Cluster of stars South Serpent - The Serpens South star cluster - Cluster of fifty very young stars (35 of which are still only proto - stars, stars in formation) observed by the Spitzer space telescope on 27 October 2006 in the constellation of the Serpent. Located only 848 years from Earth, this cluster of stars is completely masked by interstellar dust and is only revealed in infrared light. Red filaments in the background are organic molecules, PAH (aromatic polycyclic hydrocarbons composed of carbon atoms and hydrogen. In this image, Nasa's Spitzer Space Telescope spots the Serpens South star cluster, which consists of a relatively dense group of 50 young stars - - 35 of which are protostars, or stellar infants, that are just beginning to form. Stellar members of Serpens South star cluster can be seen as the green, yellow, and orange tinted specks sitting atop the black dust lane running down the center of the image. Like raindrops, stars form when thick patches of cosmic clouds condense. Tints of green in the image represent hot hydrogen gas excited when high - speed jets of gas ejected by infant stars collide with the cool gas in the surrounding cloud. Wisps of red in the background are organic molecules called polycyclic aromatic hydrocarbons (PAHS), which are being excited by stellar radiation from a neighboring star - forming region located to the east of this image, called W40. On Earth PAHS are found on charred barbeque grills and in the sooty automobile exhaust / Bridgeman Images

PIX4582860: Remnants of the Supernova of Sails - Part of the Vela Supernova Remnant - Rest of the Supernova of Sails. The supernova exploded 12,000 years ago and is approximately 815 light years away from Earth. Image obtained with the 1.2m Schmidt UK Telescope from Siding Spring. About 120 centuries ago an inconspicuous star in what is now the constellation of Vela brightened by about 100 million times to rival the Moon as the brightest object in the night sky. This photograph shows a portion of the north - western quadrant of an expanding nebulous shell, which now surrounds the site of the explosion. Near the centre of the nebula (and not seen here) is the Vela pulsar, a rapidly - spinning neutron star only a few kilometres in diameter, the remnant of the star that exploded. This tiny object spins about 11 times a second and until recently was among the faintest stars ever studied at optical wavelengths, a far cry from its brief glory as one of the brightest stars ever seen / Bridgeman Images
PIX4582923: Remains of the supernova of the Sails - Detail - Vela supernova remnant. Detail - Detail of the rest of the supernova of the Sails. The supernova exploded 12,000 years ago. The line that crosses the image is the trace left by the passage of a satellite during the photo shoot. Image obtained with Siding Spring's 3.9m telescope. A supernova event marks the catastrophic end - point in the life of a massive star. The self - destruction of the star releases a huge amount of energy as radiation of all kinds, but a substantial fraction of the force of the explosion blasts the outer part of the supernova into an expanding shell of matter that travels through the almost empty space between the stars. As the rapidly moving blast wave encounters the relatively stationary interstellar medium it creates a very narrow, luminous shock front that appears as a faint nebula. Because the shock front is very convoluted the nebulosity appears to be highly structured and the various colours define different energy levels within the interaction. Although the star responsible for the Vela supernova remnant exploded 12,000 years ago, it is still affecting its environment / Bridgeman Images
