Image 1 - ESO's Vista Images Helix Nebula In Spectacular New Colors

[ Watch the Video ] ESO´s VISTA telescope, at the Paranal Observatory in Chile, has captured a striking new image of the Helix Nebula. This picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, as well as bringing to light a rich background of stars and galaxies. The Helix Nebula is one of the closest and most remarkable examples of a planetary nebula [1]. It lies in the constellation of Aquarius (The Water...

A star does not die without getting noticed and may even leave the universe with "fireworks." At the end of its life cycle, a star begins to collapse in the middle and throws new material into space. The new material eventually becomes incorporated into new planets and life. Now, a University of Missouri professor identified new features in the material that is being ejected from the dying star Helix Nebula. A high-resolution near-infrared image revealed new information about the knots, or...

A deep new image of the magnificent Helix planetary nebula has been obtained using the Wide Field Imager at ESO's La Silla Observatory. The image shows a rich background of distant galaxies, usually not seen in other images of this object. The Helix Nebula, NGC 7293, lies about 700 light-years away in the constellation of Aquarius (the Water Bearer). It is one of the closest and most spectacular examples of a planetary nebula. These exotic objects have nothing to do with planets, but are the...

Washington, DC -- The Helix Nebula (NGC 7293) is a challenging stargazing target for amateur astronomers. It is one of the closest planetary nebulas - a type of nebula formed from gas ejected by a dying sunlike star. Yet it is so large and spread out in the sky that it appears very dim in a telescope eyepiece. Long-exposure photographs unveil the true beauty of this celestial wonder. A new portrait of the Helix Nebula, created by the penetrating infrared gaze of NASA's Spitzer Space...

A team of French and Swiss astronomers [1] have discovered one of the lightest exoplanets ever found using the HARPS instrument [2] on ESO's 3.6-m telescope at La Silla (Chile). The new planet orbits a star belonging to the class of red dwarfs. As these stars are very common, this discovery proves crucial in the census of other planetary systems. "Our finding possibly means that planets are rather frequent around the smallest stars," says Xavier Delfosse, from the Laboratoire d'Astrophysique...

Astrobiology Magazine -- In the land rush known as extrasolar planet hunting, the most prized real estate is advertised as "Earth-like." On Monday, June 13, scientists raced to plant their flag on a burning hunk of rock orbiting a red star. This newly discovered planet is about seven times the mass of Earth, and therefore the smallest extrasolar planet found to orbit a main sequence, or "dwarf" star (stars, like our sun, that burn hydrogen). There are even smaller planets known to exist...

Arlington, Va. -- Taking a major step forward in the search for Earth-like planets beyond our own solar system, a team of astronomers has announced the discovery of the smallest extrasolar planet yet detected. About seven-and-a-half times as massive as Earth, with about twice the radius, it may be the first rocky planet ever found orbiting a normal star not much different from our Sun. All of the nearly 150 other extrasolar planets discovered to date around normal stars have been larger than...

NASA -- Looks can be deceiving, especially when it comes to celestial objects like galaxies and nebulas. These objects are so far away that astronomers cannot see their three-dimensional structure. The Helix Nebula, for example, resembles a doughnut in colorful images. Earlier images of this complex object "” the gaseous envelope ejected by a dying, sun-like star "” did not allow astronomers to precisely interpret its structure. One possible interpretation was that the Helix's...

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,...

Dumbbell Nebula -- Discovered by Charles Messier in 1764. The Dumbbell Nebula M27 was the first planetary nebula ever discovered. On July 12, 1764, Charles Messier discovered this new and fascinating class of objects, and describes this one as an oval nebula without stars. We happen to see this one approximately from its equatorial plane (approx. left-to-right in our image); from near one pole, it would probably have the shape of a ring, and perhaps look like we view the Ring...
