Probing a glowing bubble of gas and dust encircling a dying star, NASA's Hubble Space Telescope reveals a wealth of previously unseen structures. The object, called NGC 2371, is a planetary nebula, the glowing remains of a Sun-like star. The remnant star visible at the center of NGC 2371 is the super-hot core of the former red giant, now stripped of its outer layers. Its surface temperature is a scorching 240,000 degrees Fahrenheit. NGC 2371 lies about 4,300 light-years away in the...

What superficially resembles a giant moth floating in space is giving astronomers new insight into the formation and evolution of planetary systems. This is not your typical flying insect. It has a wingspan of about 22 billion miles. The wing- like structure is actually a dust disk encircling the nearby, young star HD 61005, dubbed "The Moth." Its shape is produced by starlight scattering off dust. Dust disks around roughly 100-million-year-old stars like HD 61005 are typically flat,...

Finding blue blobs in space sounds like an encounter with an alien out of a science fiction movie. But the Hubble Space Telescope's powerful vision has resolved strange objects nicknamed "blobs" and found them to be brilliant blue clusters of stars born in the swirls and eddies of a galactic smashup 200 million years ago. The findings are being reported by Duilia de Mello of the Catholic University of America, Washington, D.C. and NASA's Goddard Space Flight Center, Greenbelt, Md. and her...

Stars in our galaxy may often pump out waves of million-degree gas that make surrounding nebulas glow with x-rays. These new findings could shed light into how planetary systems form—including our own solar system, researchers said. Astrophysicists focused on the Orion Nebula, a cloud of dense and turbulent gas visible to the naked eye in the night sky, right below the belt of the constellation Orion. Four extremely bright and massive stars, called the Trapezium,...

One year after the beginning of its scientific operations, the high-capability infrared satellite AKARI continues to produce stunning views of the infrared Universe. Launched in February 2006, AKARI is making a comprehensive, multi-wavelength study of the sky in infrared light, helping to gain a deeper understanding of the formation and evolution of galaxies, stars and planetary systems. The mission is a Japan Aerospace Exploration Agency (JAXA) project with ESA and international...

In celebration of the 17th anniversary of the launch and deployment of NASA's Hubble Space Telescope, a team of astronomers is releasing one of the largest panoramic images ever taken with Hubble's cameras. It is a 50-light-year-wide view of the central region of the Carina Nebula where a maelstrom of star birth - and death - is taking place. Hubble's view of the nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing...

An international team of astronomers have collaborated to create the most detailed image ever produced of the Rosette Nebula (NGC 2237), a giant stellar nursery. The new image was assembled using data from INT Photometric H-Alpha Survey of the Northern Galactic Plane (IPHAS) and covers four square degrees of sky, equivalent in size to about twenty times the size of the full moon. Robert Greimel from the University of Graz, Austria, will present results from the survey in a talk on Wednesday...

Known as the Tarantula Nebula for its spidery appearance, the 30 Doradus complex is a monstrous stellar factory. It is the largest emission nebula in the sky, and can be seen far down in the southern sky at a distance of about 170,000 light-years, in the southern constellation Dorado (The Swordfish or the Goldfish). It is part of one of the Milky Way's neighbouring galaxies, the Large Magellanic Cloud. The Tarantula Nebula is thought to contain more than half a million times the mass of the...

The small open star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357 in Sagittarius, about 8,000 light-years away from Earth. Some of the stars in this cluster are extremely massive and emit intense ultraviolet radiation. The brightest object in the picture is designated Pismis 24-1. It was once thought to weigh as much as 200 to 300 solar masses. This would not only have made it by far the most massive known star in the galaxy, but would have put it considerably above...

A new image from NASA's Spitzer and Hubble Space Telescopes looks more like an abstract painting than a cosmic snapshot. The masterpiece shows the Orion nebula in an explosion of infrared, ultraviolet, and visible-light colors. It was "painted" by hundreds of baby stars on a canvas of gas and dust, with intense ultraviolet light and strong stellar winds as brushes. At the heart of the artwork is a set of four monstrously massive stars, collectively called the Trapezium. These behemoths are...

Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...

Saturn Nebula -- The layers of the Saturn Nebula give a complex picture of how this planetary nebula was created. The above picture, taken in April 1996 and released last week, allows a better understanding of the mysterious process that transformed a low-mass star into a white dwarf star. A computer model indicates that the central star of NGC 7009 first expelled the green gas that now appears barrel shaped. This green gas now confines stellar winds flowing from the central star,...

Owl Nebula -- Dicovered by Pierre Mchain in 1781. The Owl Nebula M97 is one of the fainter objects in Messier's catalog, discovered by Pierre Mchain on February 16, 1781. In his description of this object, Charles Messier also mentions two other nebulous objects that he (and Mchain) have seen at about the same time, but which he had not added in his printed catalog version of 1781 (in the Connaissance des Temps for 1784). As the description is obvious and he added positions by...

Orion Nebula -- Discovered 1610 by Nicholas-Claude Fabri de Peiresc. Located at a distance of about 1,600 (or perhaps 1,500) light years, the Orion Nebula is the brightest diffuse nebula in the sky, visible to the naked eye, and rewarding in telescopes of every size, from the smallest glasses to the greatest Earth-bound observatories and the Hubble Space Telescope. It is the main part of a much larger cloud of gas and dust which extends over 10 degrees well over half the constellation...

Hubble's Variable Nebula -- Hubble's variable nebula is named (like the Hubble telescope itself) after the American astronomer Edwin P. Hubble, who carried out some of the early studies of this object. It is a fan-shaped cloud of gas and dust which is illuminated by R Monocerotis (R Mon), the bright star at the bottom end of the nebula. Dense condensations of dust near the star cast shadows out into the nebula, and as they move the illumination changes, giving rise to the variations first...
