The simple answer is: It could, but it won't. It will, however, produce a spectacular light show. It's an enormous star — 120 times the weight and 240 times the size of our Sun.
Is Eta Carinae a threat?
At any time its core could collapse into a black hole, which may result in a gamma-ray burst (GRB) that can devastate life on Earth. ...
Will Eta Carinae become a black hole?
Each star in the Eta Carinae system is massive enough to form a neutron star in a supernova explosion. Because we've observed black holes in binary systems with a massive star companion, it is a good bet that the most massive stars like Eta Carinae do collapse to black holes.
Will Eta Carinae go supernova?
According to astronomers, Eta Carinae will end its intermittent fireworks display with a final show-stopping number: a supernova. And that will far outshine any of its previous outbursts. ... Since we're 7500 light years away from it all, that light may already be on its way to us, and Eta Carinae could already be dead.
Did Eta Carinae explode?
As though in preparation for summer festivities, the Hubble Space Telescope captured this cosmic fireworks show from Eta Carinae. The double star system, glowing in red, white, and blue, has exploded several times. ... Once an important star to navigators, Eta Carinae is no longer visible to the naked eye on Earth.
How did Eta Carinae survive a supernova?
Why are astronomers so interested in the Eta Carinae system?
These oval-shaped trajectories give astronomers a chance to study what happens to the winds from these stars when they collide at different distances from one another. Throughout most of the system's orbit, the X-rays are stronger at the apex, the region where the winds collide head-on.
How far away is Eta Carinae from Earth?
Eta Carinae is one of the most massive binary star systems known, lying at a distance of about 7,500 light years from Earth.
Is Eta Carinae in the Milky Way?
Eta 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.
Is AG Carinae visible from Earth?
AG Carinae (AG Car) is a star in the constellation Carina. ... The great distance (20,000 light-years) and intervening dust mean that the star is not usually visible to the naked eye; its apparent brightness varies erratically between magnitude 5.7 and 9.0.
What is the solar mass of Eta Carinae?
Most observations point out that it has between 30 to 80 solar masses and a radius between 14.3 to 23.6 solar radii. Eta Carinae B is speculated to be 1 million times brighter than our sun.
Why would a massive star like Eta Carinae be so unstable?
Eta Carinae's past outbursts and pulsations are probably linked to instabilities between its inner layers created when it exhausted one nuclear fuel and transitioned to another.
What caused the great eruption of Eta Carinae?
The Hubble Space Telescope captured the glory of Homunculus Nebula, created in 1843 during an upheaval by the supermassive star Eta Carinae at its center. A nasty case of sibling rivalry may have caused an explosion in the massive star system known as Eta Carinae.
How big is Eta Carinae compared to the sun?
UPDATE! As of January 2009, we now know about some other really big stars. One is called Eta Carinae. It has a size about 800 times that of our Sun, a mass about 100 times that of our Sun, and is about 4,000,000 times brighter than our Sun.
What is oldest thing in universe?
Quasars are some of the oldest, most distant, most massive and brightest objects in the universe. ... This quasar in particular, named P172+18, is a relic from around 780 million years after the Big Bang and reveals clues about one of the earliest ages of the universe — the epoch of reionization.
Is Eta Carinae a Wolf Rayet star?
Wolf–Rayet stars are named after the two French astronomers who first identified them in the mid-nineteenth century, and WR 22 is one of the most massive ones we know of. ... This area includes the famous star Eta Carinae, one of the most massive stars and unstable stars in the universe.
What is the Mystic Mountain in space?
Within the tempestuous Carina Nebula lies “Mystic Mountain.” This three-light-year-tall cosmic pinnacle, imaged by the Hubble Space Telescope's Wide Field Camera 3 in 2010, is made up primarily of dust and gas, and exhibits signs of intense star-forming activity.
How many stars make up Eta Carinae?
One of the Milky Way's most impressive star systems, about 8,000 light-years away in the southern constellation Carina. It probably consists of two stars, each of which is many times as massive as the Sun. The stars are surrounded by a thick, dusty nebula that makes it impossible to see one of the stars.
How do Hypergiants form?
Creation of Hypergiant Stars. All stars form in clouds of gas and dust, no matter what size they end up being. It's a process that takes millions of years, and eventually the star "turns on" when it starts to fuse hydrogen in its core. That's when it moves onto a period of time in its evolution called the main sequence ...
How big is a blue Hypergiant star?
The true monsters of the Universe are the blue hypergiant stars, like Eta Carinae. It has 150 times the mass of the Sun, and measure up to 180 times the size of the Sun.
Is Eta Carinae main sequence?
In 1843 Eta Carinae became the second brightest star in the night sky. ... The star grows rather quickly after being in the main sequence star becaus ethe mass of the star is so large that its burns through its fuel quickly.
How old is the universe?
Using data from the Planck space observatory, they found the universe to be approximately 13.8 billion years old.
