What will happen when Stephenson 2-18 dies?

What will happen when Stephenson 2-18 dies?

As Stephenson 2-18 continues to burn elements in it’s core, it will die eventually, giving it’s mass back to the Galaxy. This mass will create new stars and planets.

Is Stephenson 2/18 a black hole?

Stephenson 2-18 is a Red hypergiant Star that is in the constellation of Scutum within the Star cluster of Stephenson 2. It is 19,570 light-years away from the Earth, near the supermassive black hole named Sagittarius A*. It is the largest Star in the Galaxy.

Why is Stephenson 2-18 so big?

Stephenson 2-18 is a red supergiant. It would have started as a very massive main sequence star, and become a supergiant after the end of core hydrogen burning. During shell burning, stars expand as they blow off gases into the envelope. This expansion creates red giants.

How far is Stephenson 2-18 from Earth?

Will the star explosion in 2022 destroy Earth?

What is the hottest star in the universe?

The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.

What Blackhole is closest to Earth?

Gaia BH1 is the closest black hole to Earth that scientists have ever discovered. It is approximately three times closer to Earth than the previous record holder. By looking at the behavior of a star near the black hole, astronomers could determine the black hole was there, despite never seeing it directly.

Has NASA seen a black hole?

Multiple NASA telescopes recently observed a massive black hole tearing apart an unlucky star that wandered too close. Located about 250 million light-years from Earth in the center of another galaxy, it was the fifth-closest example of a black hole destroying a star ever observed.

What is the biggest black hole on Earth?

The one at the center of our galaxy is called Sagittarius A*. This black hole has a mass of about 4.154×106 solar masses.

What is the largest known star?

The largest known star in the universe, UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun. To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti.

What old is the Sun?

Our Sun is 4,500,000,000 years old. That’s a lot of zeroes. That’s four and a half billion.

How big is the universe?

While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is approximately 93 billion light-years in diameter at the present day.

How big is the Milky Way?

Is Earth gonna explode?

No. Planets don’t explode. They’re held together very strongly by gravity and there’s no force that could come from inside powerful enough to blow them apart. Planet can be smashed by impact with similar size bodies, but there’s no such threat coming our way.

Will the Earth be destroyed in 5 billion years?

Earth will interact tidally with the Sun’s outer atmosphere, which would decrease Earth’s orbital radius. Drag from the chromosphere of the Sun would reduce Earth’s orbit. These effects will counterbalance the impact of mass loss by the Sun, and the Sun will likely engulf Earth in about 7.59 billion years.

What star can destroy Earth?

It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer. Such estimates are based on atmospheric modeling and the measured radiation flux from SN 1987A, a Type II supernova in the Large Magellanic Cloud.

Is Stephenson 2-18 in the Milky Way?

St2-18 shows the traits and properties of a highly luminous red supergiant, with a spectral type of M6, which is unusual for a supergiant star. This makes it one of the most extreme stars in the Milky Way.

What did Stephenson do to Raptors?

Not only did Stephenson’s decision to head to the tin with time winding down incite an altercation on the floor, but it provoked Raptors swingman PJ Tucker to lash out at him after the game.
