What is special about the Carina Nebula?
Eta Carinae is a highly luminous hypergiant star. Estimates of its mass range from 100 to 150 times the mass of the Sun, and its luminosity is about four million times that of the Sun. This object is currently the most massive star that can be studied in great detail, because of its location and size.
What is the oldest nebula?
Dumbbell Nebula (M27): The first recorded planetary nebula, the Dumbbell Nebula lies 1,200 light-years away from Earth.
Is the Carina Nebula in the Milky Way?
Spanning over 300 light-years, the Carina Nebula is one of the Milky Way’s largest star-forming regions and is easily visible to the unaided eye under dark skies.
How far away is the Carina Nebula from Earth?
7,500 light years
Carina Nebula/Distance to Earth
How did the Carina Nebula form?
The first generation of newly formed stars in the nebula are believed to have condensed some three million years ago, igniting in the middle of a large hydrogen cloud. Radiation from these young stars shaped a bubble of hot gas, which has kept expanding ever since.
Whats in the Carina Nebula?
The immense nebula contains at least a dozen brilliant stars that are roughly estimated to be at least 50 to 100 times the mass of our Sun. The most unique and opulent inhabitant is the star Eta Carinae, at far left.
What is Carina in space?
The Carina Nebula is a star-forming region in the Sagittarius-Carina arm of the Milky Way that is 7,500 light years from Earth and the Chandra X-Ray Observatory has detected more than 14,000 stars in the region. Previous observations had only detected one neutron star in Carina.
Who discovered Carina Nebula?
Nicolas Louis de Lacaille
Lewis) The Carina Nebula (NGC 3372) is a massive star-forming region within the Milky Way. Officially discovered by French astronomer Nicolas Louis de Lacaille in the 1750s, the nebula stretches over 300 light-years across, so big and bright that it’s easy to spot with the naked eye.

What does the Carina Nebula look like?
Eta Carinae appears as the bright ball of light just above the “v” of dark material at center; the Keyhole Nebula is to the right of Eta Carinae’s glow. The Carina Nebula (NGC 3372) is a massive star-forming region within the Milky Way.
How many light years across is the Carina Nebula?
260 light years
It contains two of the most massive and luminous stars in our Milky Way galaxy, Eta Carinae and HD 93129A. Located 7500 light years away, the nebula itself spans some 260 light years across, about 7 times the size of the Orion Nebula, and is shown in all its glory in this mosaic.
What type of nebula is the Swan Nebula?
Where is the Carina Nebula located in the Milky Way?
The Carina Nebula is a star-forming region in the Sagittarius-Carina arm of the Milky Way, found 7,500 light years from Earth. Ultra-dense neutron stars are rare in this cloud of gas and dust, but more of these stellar corpses will be forming in the (relatively) near future.
What kind of effect does Eta Carina have on Nebula?
Eta Carinae’s effects on the nebula can be seen directly. Dark globules and some other less visible objects have tails pointing directly away from the massive star.
How big is Trumpler 14 in the Carina Nebula?
Trumpler 14 is an open cluster with a diameter of six light-years (1.8 pc), located within the inner regions of the Carina Nebula, approximately 8,000 light-years (2,500 pc) from Earth. It is one of the main clusters of the Carina OB1 stellar association, which is the largest association in the Carina Nebula.
What kind of telescope was used to see Carina Nebula?
Rice University’s Patrick Hartigan and Andrea Isella, together with Dublin City University’s Turlough Downes, used the 8.1-meter Gemini South telescope to capture near-infrared images of the Carina Nebula, with the same resolution expected from the James Webb Space Telescope, due for launch in 2021.
