New observations of magnetic jets may shed some light on how stars transition into planetary nebulae.

Bizarre Alignment Observed In Butterfly-Shaped Nebulae
2013-09-04 08:57:07

Planetary nebulae occur in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. These nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape.

Life Of Eskimo Nebula Coming To A Beautiful End

At the end of their lives, stars like our Sun become remarkably photogenic. For example, NGC 2392, located approximately 4,200 light years from Earth, is giving astronomers a beautiful display as it nears the end of its existence.

Hubble Provides Most Detailed Image Of Ring Nebula To Date
2013-05-23 12:48:25

The Hubble Space Telescope has provided one of the most detailed images of the Ring Nebula so far, allowing scientists to construct a model of the nebula in 3D.

Planetary nebula IC 1295

An international team of astronomers are reporting in The Astrophysical Journal they have spotted what resembles a soccer ball sitting in the dying star M1-11.

Astronomers Shed Light On Old Star Using New Greek Observatory
2013-02-27 08:44:17

Continuing a tradition stretching back more than 25 centuries, astronomers have used the new 2.3-m 'Aristarchos' telescope, sited at Helmos Observatory (2340m high) in the Pelοponnese Mountains in Greece, to determine the distance to and history of an enigmatic stellar system, discovering it to likely be a binary star cocooned within an exotic nebula.

Hubble Image Of Planetary Nebula Resembles Christmas Ribbon

NASA and the ESA reveal a Hubble Space Telescope image of a planetary nebula that resembles a Christmas ribbon.

Dying Star Caught Coming Back To Life

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...

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...

Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...

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,...

Ring Nebula -- Discovered by Antoine Darquier de Pellepoix in 1779. The famous ring nebula M57 is often regarded as the prototype of a planetary nebula, and a showpiece in the northern hemisphere summer sky. Recent research has confirmed that it is, most probably, actually a ring (torus) of bright light-emitting material surrounding its central star, and not a spherical (or ellipsoidal) shell, thus coinciding with an early assumption by John Herschel. Viewed from this equatorial...
