PIX4623668: Planetary nebula NGC 7662 in Andromede - Planetary nebula NGC 7662 in Andromeda - A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its material. Image obtained with a 50 cm telescope, 3 times 30 minutes of installation. Like The Eskimo Nebula, NGC 7662 is a challenging target with extremely small details. Its inner region is dominated by a relatively smooth torus with only hints of filamentary structures in the very center. While the data is comprised of only 30 minutes in each color, it is possible to detect the outer halo of this planetary nebula / Bridgeman Images
PIX4623685: Planetary nebula IC 4406 dans le Loup/HST - One of the most interesting features of IC 4406, the “” Retina Nebula””, is the irregular lattice of dark lanes that criss - cross the center of the nebula. These lanes are about 160 astronomical units wide (1 astronomical unit is the distance between the Earth and Sun). They are located right at the boundary between the hot glowing gas that produces the visual light imaged here and the neutral gas seen with radio telescopes. We see the lanes in silhouette because they have a density of dust and gas that is a thousand times higher than the rest of the nebula. The dust lanes are like a rather open mesh veil that has been wrapped around the bright donut. This image is a composite of data taken by Hubble's Wide Field Planetary Camera 2 in June 200 / Bridgeman Images
PIX4623698: Planetary Nebula Hen - 1357 dans l'Altar/HST - This Wide Field and Planetary Camera 2 image captures the infancy of the Stingray nebula (Hen - 1357), the youngest known planetary nebula. In this image, the bright central star is in the middle of the green ring of gas. Its companion star is diagonally above it at 10 o'clock. A spur of gas (green) is forming a faint bridge to the companion star due to gravitational attraction. The image also shows a ring of gas (green) surrounding the central star, with bubbles of gas to the lower left and upper right of the ring. The wind of material propelled by radiation from the hot central star has created enough pressure to blow open holes in the ends of the bubbles, allowing gas to escape. The red curved lines represent bright gas that is heated by a “” shock””” caused when the central star's wind hits the walls of the bubbles. The nebula is as large as 130 solar systems, but, at its distance of 18,000 light - years, it appears only as big as a dime viewed a mile away. The Stingray is located in the direction of the southern constellation Ara (the Altar). The colors shown are actual colors emitted by nitrogen (red), oxygen (green), and hydrogen (blue). The filters used were F658N ([N II]), F502N ([O III]), and F487N (H - beta). The observations were made in March 1996 / Bridgeman Images
PIX4620508: Nebula NGC 7023 in Cephee - Iris Nebula in Cepheus - The nebula of the Iris (NGC 7023) is a reflexion nebula illuminated by the star HD 200775. NGC 7023 (The Iris Nebula) Distance: 1400 Light Years The bright star HD 200775 shining through the nebula NGC 7023 is a 10 solar mass star centrally imbedded in a region surrounded by ambient molecular cloud material / Bridgeman Images
PIX4619938: Eagle Nebula (IC 4703) and M16 star cluster in the Snake - Eagle Nebula (IC 4703) and M16 star cluster in the Snake - Messier 16 is a cluster of stars formed about 2 million years ago from the gas and dust that still surrounds it today. The nebula always forms new stars. It is located about 7000 light years from Earth in the constellation Serpent / Bridgeman Images
PIX4621267: Molecular cloud B 68 in Ophiuchus seen in infrared - False - colour composite based on a visible (here rendered as blue), a near - infrared (green) and an infrared (red) image. Since the light from stars behind the cloud is only visible at the longest (infrared) wavelengths, they appear red. At a distance of only 410 light - years, Barnard 68 is one of the nearest dark clouds. Its size is about 12,500 AU (= 2 million km; 1 Astronomical Unit [AU] = 150 million km), or just about the same as the so - called “” Oort Cloud””” of long - period comets that surrounds the solar system. The temperature of Barnard 68 is 16 Kelvin (- 257* C) The total mass of the cloud is about twice that of the Sun / Bridgeman Images
PIX4622614: Nebula IC 4628 and star clusters in Scorpio - Nebula IC 4628 and star clusters in Scorpio - Nebula IC 4628 in the middle left of the image is surrounded at the bottom by the star cluster NGC 6231, and by the NGC 6242 cluster at the top of the image. A beautiful collection of open clusters and nebulosity is seen here in Scorpius, just north of the double star Zeta Scorpii. Zeta is visible at the far bottom right and is also know as the “Little Cat's Eyes””. NGC 6231 is a lovely open cluster above Zeta. IC 4628 is the emission nebula just northeast of two loose open clusters, Cr 316 and Tr 24 in the center of the photo. NGC 6242 is the other small open cluster at top left.

PIX4622715: Cocon Nebula (IC 5146) in Swan - Cocon Nebula (IC 5146) in Swan - Cocon Nebula is located about 4000 light years from Earth in the constellation Swan. It's a star-forming region. Image obtained by the Oschin telescope of Mount Palomar through several filters and composed / Bridgeman Images
