NASA Observatories Take an Unprecedented Look into Superstar Eta Carinae
2015年1月6日 · Located about 7,500 light-years away in the southern constellation of Carina, Eta Carinae comprises two massive stars whose eccentric orbits bring them unusually close every 5.5 years. Both produce powerful gaseous outflows called stellar winds, which enshroud the stars and stymy efforts to directly measure their properties.
Watch the Great Eruption of a Massive Star: Eta Carinae
2022年4月19日 · Eta Carinae is a prime example of the outbursts in the dying stages of very high mass stars. In addition, the team has released a shorter video focused on the layers seen in visible, Hydrogen Alpha, ultraviolet, and x-ray observations.

2023年11月30日 · Eta Carinae (η Car) is a massive binary star system located approximately 7,500 light-years away in the constellation Carina. The system consists of two exceptionally massive stars that will end their lives as supernovae.
Eta Carinae - Simple English Wikipedia, the free encyclopedia
Eta Carinae (η Carinae or η Car) is a superbright hypergiant star in the constellation Carina, about 7,500 to 8,000 light-years from the Sun. The system contains at least two stars, of which the primary is a luminous blue variable (LBV) that initially had around 150 solar masses, of which it has lost at least 30.
Doomed Star Eta Carinae - Science@NASA
Eta Carinae, in the Keyhole Nebula, is the only star currently thought to emit natural LASER light. This featured image brings out details in the unusual nebula that surrounds this rogue star. Diffraction spikes, caused by the telescope, are visible as bright multi-colored streaks emanating from Eta Carinae's center.
Eta Carinae
Eta Carinae (η Car) is the most luminous, most powerful star visible to the unaided eye. Several facts make it unique for astrophysics. It is the only supernova impostor or giant eruption survivor close enough to observe well.
Eta Carinae : General Info
Eta Carinae is the most massive and luminous star in our part of the Milky Way galaxy. It is a naked-eye object visible to observers in the southern hemisphere and the tropics. In the 1850's it briefly became the second brightest star in the sky.
