Not exact matches

In contrast, Immanuel Kant and Pierre de Laplace argued that planetary development was part of a normal process to be expected in the life of almost every star: they assumed the young sun was surrounded by a thin lens - shaped gaseous envelope (solar nebula) which later condensed into planets.

For decades, astronomers have suspected that planetary nebulae — dazzlingly colorful shrouds of gas cast off by dying stars — owe their weird but often symmetrical shapes to the sculpting magnetic forces of two stars orbiting each other at the nebula's center.

The final stages of life for a star like our Sun result in the star blowing its outer layers out into the surrounding space, forming objects known as planetary nebulae in a wide range of beautiful and striking shapes.

One type of such nebulae, known as bipolar planetary nebulae, create ghostly hourglass or butterfly shapes around their parent stars.

Most satisfying of all, the menagerie of simulated planetary nebula shapes looked a lot like the creatures in the real planetary nebula zoo.

A dark ring of dust and gas circling the star (dark bands, center), material that may one day coalesce into a planetary system, acts like a belt, cinching the nebula into an hourglass shape.

The ESO's Very Large Telescope (VLT) has captured a beautiful image of a planetary nebula known as NGC 7009, or the Saturn Nebula, as part of a wider study attempting to unravel the processes that give these vast cosmic clouds of dust and glowing gas their distinctive nebula known as NGC 7009, or the Saturn Nebula, as part of a wider study attempting to unravel the processes that give these vast cosmic clouds of dust and glowing gas their distinctive Nebula, as part of a wider study attempting to unravel the processes that give these vast cosmic clouds of dust and glowing gas their distinctive shape.

The name «planetary nebula» refers only to the round shape that many of these objects show when examined through a small telescope.

Such elongated shapes are common among other planetary nebulae, because thick disks of gas and dust form a waist around a dying star.

The Hubble telescope has shown us that the shrouds of gas surrounding dying, Sun - like stars (called planetary nebulae) come in a variety of strange shapes, from an «hourglass» to a «butterfly» to a «stingray.»

This star system could explain a dazzling variety of glowing shapes uncovered by Hubble that are seen around dying stars, called planetary nebulae, researchers say.
