η Carinae is found within the Carina Nebula, a giant star-forming region in the Carina–Sagittarius Arm of the Milky Way. The nebula is a prominent naked-eye object in the southern skies showing a complex mix of emission, reflection and dark nebulosity. η Carinae is known to be at the same distance as the Carina Nebula and its spectrum can ...
Various properties of stars can also be used to determine their age. For example, the Eta Carinae system is emitting large quantities of gas and dust. These enormous outbursts can be used to infer that the star system is nearing the end of its life, and will explode as a supernova within a relatively short period of astronomical time. [6]
Eta Carinae is known to be at the same distance as the Carina Nebula and its spectrum can be seen reflected off various star clouds in the nebula. [76] The appearance of the Carina Nebula, and particularly of the Keyhole region, has changed significantly since it was described by John Herschel over 160 years ago. [ 46 ]
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
Some luminous blue variables are classified as hypergiants, during at least part of their cycle of variation: AG Carinae, a massive Luminous blue variable and a part of the Carina constellation, which is transitioning from an O-type star to a Wolf-Rayet star. Eta Carinae, inside the Carina Nebula in the southern constellation of Carina. Eta ...
Fine dust thrown up into Earth’s atmosphere after an asteroid strike 66 million years ago blocked the sun to an extent that plants were unable to photosynthesize, a new study has found.
Luminous blue variable stars can undergo "giant outbursts" with dramatically increased mass loss and luminosity. η Carinae is the prototypical example, [20] with P Cygni showing one or more similar outbursts 300–400 years ago, [21] but dozens have now been catalogued in external galaxies.
Not every TV couple gets to live happily ever after. The star-crossed lovers found in the list below may have had their relationships torn asunder by death, major life changes or even off-screen ...
