NGC 6302 WALLPAPER

ngc 6302

This object is an example of a planetary nebula, so-named because many of them have a round appearance resembling that of a planet when viewed through a small telescope. More popularly known as the Bug Nebula or the Butterfly Nebula, this celestial object looks like a delicate butterfly. Later, as the central star heated up, a much faster stellar wind, a stream of charged particles traveling at more than 2 million miles 3 million kilometers an hour, plowed through the existing wing-shaped structure, further modifying its shape. The glowing gas is the star’s outer layers, expelled over about 2, years. The white blob with the crisp edge at upper right is an example of one of those shock waves. NGC belongs to a group of objects where hydrocarbon molecules formed in an oxygen-rich environment [13].

New General Catalogue to It was not seen in the first Hubble Space Telescope images; [6] the improved resolution and sensitivity of the new Wide Field Camera 3 of the same telescope later revealed the faint star at the centre.

NGC 6302 (ground-based)

bgc The star first evolved into a huge red-giant star, with a diameter of about 1, times that of our Sun. These are regions where fast-moving gas overtakes and collides with slow-moving gas that left the star at an earlier time, producing shock waves in the gas the bright white edges on the sides facing the central star.

It then lost its extended outer layers. Later, as the central star heated up, a much faster stellar wind, a stream of charged particles traveling at more than 2 million miles 3 million kilometers an hour, plowed through the existing wing-shaped structure, further modifying its shape.

Interest in recent years has shifted from discussions over the excitation 630 in the nebula shock-excitation or photo-ionisation to the properties of the large dust component.

WFC3 is equipped with a wide variety of filters gnc isolate light emitted by various chemical elements, allowing astronomers to infer properties of the nebular gas, such as its temperature, density, and composition.

Big, Bright, Bug Nebula”. The star’s surface temperature is estimated to be aboutdegrees 63302, making it one of the hottest known stars in our galaxy. Some of this gas was cast off from its equator at a relatively slow speed, perhaps as low as 20, miles an hour, creating the torus. This allows the hot, inner core of the star collapsing from a red giant to a white dwarf to radiate strongly, causing this outward-moving cocoon of gas to glow brightly. Sep 9, Image Use: The structure in the nebula is among the most complex ever observed in planetary nebulae.

O’Meara argues that Barnard credited it to Dunlop – but may have been mistaken. Previous Image Next Image. NGC is bipolar with two primary lobes, though there is evidence for a second pair of lobes that may have belonged to a previous phase of mass loss.

Wikimedia Commons has media related to NGC Our own Nfc is expected to undergo a similar fate, but fortunately this will not occur until some 5 billion years from now. The star has a current mass of around 0. Ntc Wikipedia, the free encyclopedia. The star first evolved into a red giant with a diameter of about 1, 66302 that of our Sun.

The image also shows numerous finger-like projections pointing back to the star, which may mark denser blobs in the outflow that have resisted the pressure from the stellar wind. The structure in the nebula is among the most complex ever observed in planetary nebulae.

The central star, among the hottest stars known, had escaped detection because of a combination of its high temperature meaning that it radiates mainly in the ultravioletthe dusty torus which absorbs a large fraction of the light from the central regions, especially in the ultraviolet and the bright background from the star. The prominent dark lane that runs through the centre of the nebula has been shown to have an extraordinary dust chemistry, showing evidence for multiple crystalline silicates, crystalline water ice and quartzwith other features which have been interpreted as the first extra-solar detection of carbonates.

The central star, a white dwarfwas only recently discovered Szyszka et al. The gas is tearing across space at more thanmiles an hour — fast enough to travel from Earth to the Moon in 24 minutes. The original mass of the star was much higher, but most was ejected in the event which created the planetary nebula.

InSzyszka and his team further analyzed Hubble data to determine the motions of two lobes of the ejected material, which appear to have been created rapidly in an event 2, years ago. By using this site, you agree to the Terms of Use and Privacy Policy.

Some of this gas was cast off from its equator at a relatively slow speed, perhaps as low as 20, miles 32, kilometers an hour, creating the doughnut-shaped dust belt. The nebula’s reddish outer edges are largely due to light emitted by nitrogen, which marks the coolest gas visible in the Hubble image.
