How hot is the Bug Nebula?
How hot is the Bug Nebula?
about 400,000 degrees Fahrenheit
The thick dust belt constricts the star’s outflow, creating the classic “bipolar” or hourglass shape displayed by some planetary nebulae. The star’s surface temperature is estimated to be about 400,000 degrees Fahrenheit, making it one of the hottest known stars in our galaxy.
How old is NGC 6302?
As it is included in the New General Catalogue, this object has been known since at least 1888. The earliest-known study of NGC 6302 is by Edward Emerson Barnard, who drew and described it in 1907.
What is in the center of the Bug Nebula?
The Bug Nebula, NGC 6302, is one of the brightest and most extreme planetary nebulae known. At its centre lies a superhot, dying star smothered in a blanket of hailstones. The fiery, dying star at its centre is shrouded by a blanket of icy hailstones.
What galaxy is the Butterfly Nebula in?

What is the hottest nebula?
Its surface temperature is probably 150,000-250,000 K although a temperature of 340,000 K or even 500,000 K is not ruled out, making it among the hottest white dwarf stars known….Red Spider Nebula.

What is the closest nebula to Earth?
the Helix Nebula
The nearest nebula to earth is the Helix Nebula. It is 700 light years away from Earth. Most of them are less dense than any vacuum created on earth and a nebular cloud of the size of Earth would have a total mass of only a few kgs.
What caused the Butterfly Nebula?
They blasted away from the star in all directions, but the thick disk of dust slowed the gas traveling along the orbital plane. The result was two opposing jets of hot gas racing away from the star at hundreds of thousands of miles per hour, creating the wings of the butterfly.
How Hot Is a Butterfly Nebula?
about 250,000 degrees C
With an estimated surface temperature of about 250,000 degrees C, the dying central star of this particular planetary nebula has become exceptionally hot, shining brightly in ultraviolet light but hidden from direct view by a dense torus of dust.
What happens if a star gets too hot?
If the star is large enough, it can go through a series of less-efficient nuclear reactions to produce internal heat. However, eventually these reactions will no longer generate sufficient heat to support the star agains its own gravity and the star will collapse.
What is the hottest star color?
Blue stars
White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
What causes a nebula?
A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called “star nurseries.”
Is Earth in a nebula?
The Earth was formed from the nebula that produced the Solar System. It is almost universally accepted that the Sun, the planets and their satellites, the asteroids, and the comets of the Oort ‘cloud’ grew from a cloud of gas and dust that contracted under its own gravity.
What kind of Nebula is the Butterfly Nebula?
It is sometimes also called the Bug Nebula. It has the designation NGC 6302 in the New General Catalogue. The Butterfly Nebula has one of the most complex structures ever seen in a planetary nebula.
Is there a butterfly in the nebula NGC 6302?
Butterfly Emerges from Stellar Demise in Planetary Nebula NGC 6302. This celestial object looks like a delicate butterfly. But it is far from serene. What resemble dainty butterfly wings are actually roiling cauldrons of gas heated to more than 36,000 degrees Fahrenheit.
Which is the most complex nebula in Scorpius?
Jump to navigation Jump to search. NGC 6302, also called the Bug Nebula, Butterfly Nebula, is a bipolar planetary nebula in the constellation Scorpius. The structure in the nebula is among the most complex ever observed in planetary nebulae.
Which is the hottest star in the Nebula?
The structure in the nebula is among the most complex ever observed in planetary nebulae. The spectrum of NGC 6302 shows that its central star is one of the hottest stars known, with a surface temperature in excess of 250,000 degrees Celsius, implying that the star from which it formed must have been very large.
