about 250,000 degrees CWith 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.

How many nebula are there?

3,000Right now, we know of about 3,000 planetary nebulae in our galaxy, the Milky Way, out of roughly 200 billion stars. Most of them are near the center of our galaxy. They come in many shapes, but most are spherical, elliptical, or bipolar.

What is special about the Helix nebula?

The Helix Nebula was the first planetary nebula discovered to contain cometary knots. Its main ring contains knots of nebulosity, which have now been detected in several nearby planetary nebulae, especially those with a molecular envelope like the Ring nebula and the Dumbbell Nebula.

What type of nebula is the Butterfly Nebula?

bipolar planetary nebulaThe Butterfly Nebula is a bipolar planetary nebula located in Scorpius. It lies at a distance of 3,800 light years from Earth. Named for its resemblance to a butterfly, the nebula has a wingspan that stretches across three light years. It is sometimes also called the Bug Nebula.

What’s bigger galaxy or nebula?

Simply put, the main difference between galaxies and nebulae are an extreme difference in size, as well as their basic structure. A nebula is a cloud of dust and gas, usually tens to hundreds of light years across. A galaxy is much larger — usually thousands to hundreds of thousands of light years across.

Can you see the Helix nebula?

The nebula’s striking appearance earned it the nickname the Eye of God. The Helix Nebula is a popular object for amateur astronomers and can be observed with binoculars, which reveal it as a hazy, greenish cloud. The nebula appears as almost one-half the Moon’s diameter.

Which nebula is Earth in?

What is the biggest nebula in the universe?

Tarantula NebulaLargest Nebula: The Tarantula Nebula Both the largest known nebula and most active star-forming region in our local galactic neighborhood, the Tarantula Nebula stretches for more than 1,800 light-years at its longest span.

What is at the center of the Bug Nebula?

The glowing gas is the star’s outer layers, expelled over about 2,200 years. … The central star itself cannot be seen, because it is hidden within a doughnut-shaped ring of dust, which appears as a dark band pinching the nebula in the center.

Is the Helix nebula in the Milky Way?

The double helix nebula is approximately 300 light years from the enormous black hole at the center of the Milky Way. … Spitzer is an infrared telescope that is imaging the sky at unprecedented sensitivity and resolution, enabling it to see the double helix nebula clearly.

What does the Helix nebula look like?

The glowing cloud, called the Helix Nebula, looks like a bubble in this Hubble Space Telescope image. … We don’t see the elongated shape because one end of the tubular-shaped nebula is pointed toward Earth. The Helix is an example of a planetary nebula, the expanding shell of glowing gas around a dying, Sun-like star.

What does planetary nebula mean?

A planetary nebula, abbreviated as PN or plural PNe, is a type of emission nebula consisting of an expanding, glowing shell of ionized gas ejected from red giant stars late in their lives. … All planetary nebulae form at the end of the life of a star of intermediate mass, about 1-8 solar masses.

How did the Helix nebula get its name?

The Helix gets its name from its ring-like appearance which resembles the two coils of a spring seen on axis. When you first see the Helix Nebula, you may be astonished to discover how large it appears.
