Eta Carinae, the most luminous and massive stellar system located within 10,000 light-years of Earth, is best known for an enormous eruption seen in the mid-19th century that hurled an amount of ...

(Phys.org) —The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the ...

A huge star system 7,500 light-years away is shooting out radiation at superhigh speeds. A new study with NASA's NuSTAR space telescope shows that Eta Carinae may act as an accelerator of charged ...

The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the Sun, ...

Eta Carinae, about 8,000 light-years from Earth, was classified as a variable star in the 19th century, when astronomers observed it slowly changing in brightness.

Eta Carinae shines brightly in the infrared, and one of its larger "space environment" implications is how it affects the Carina Nebula in which the exploding object resides, NASA noted.

Eta Carinae, an enigmatic star that has mystified astronomers for 160 years with both its sheer beauty and massive size, is repeating a roughly five-year cycle of pumping out X rays. This finding ...

Beginning in 1837, the star Eta Carinae, located about 7,500 light-years away in the constellation Carina the Keel, underwent a tremendous explosion.The prodigious outpouring of energy ...

Eta Carinae is eating itself. The best fuel has already been burnt, so now less stable substances are roiling around in the star’s core — causing “puffs” of star-stuff to be cast off into ...

AS stars go, Eta Carinae is big. It’s old. It’s volatile. And it’s about to blow. So will it really kill us all? The eyes of astronomers have been on this star for decades. And with good ...

Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th century for reasons scientists still ...
