Is Stephenson in the Milky Way?
Is Stephenson in the Milky Way?
Stephenson 2 , also known as RSGC2 (Red Supergiant Cluster 2), is a young massive open cluster belonging to the Milky Way galaxy.
Is Stephenson 2-18 visible from Earth?
Stephenson 2-18 is a member of the open cluster Stephenson 2, which occupies an area of 1.8′ of the sky but is not visible in amateur telescopes. The cluster cannot be detected in visible light at all because it is heavily obscured by dust, but it can be seen in infrared light.
Where is a Stevenson 2 18 located?
How far is Stephenson 2-18 from Earth?
Is Stephenson 2/18 located 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.
Who saw the Milky Way galaxy?
Galileo was the first to see the Milky Way Galaxy in 1610 as individual stars through the telescope.
What is the biggest known star in the universe?
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 is the hottest star in the universe?
The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
How big is the Milky Way?
How many stars in a galaxy?
Using the Milky Way as our model, we can multiply the number of stars in a typical galaxy (100 billion) by the number of galaxies in the universe (2 trillion).
How many Earths can fit inside Stephenson 2-18?
Sun (our star) – About 1.3 million Earths can fit inside the sun. Stephenson 2-18 (the largest known Star) – About 8 million Suns can fit inside Stephenson 2-18.
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.
What is the closest black hole to Earth?
Located just under 1,600 light-years away, the discovery suggests there might be a sizable population of dormant black holes in binary systems. The black hole Gaia BH1, seen in this artist’s concept near its Sun-like companion star, is the closest black hole to Earth discovered so far.
Is Stephenson 2-18 bigger than 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.
How many galaxies are there?
The Hubble Deep Field, an extremely long exposure of a relatively empty part of the sky, provided evidence that there are about 125 billion (1.25×1011) galaxies in the observable universe.
What is the 2 closest galaxy to the Milky Way?
The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Sagittarius Dwarf Elliptical Galaxy is the next closest , at 662,000,000,000,000,000 km (70,000 light years) from the Sun.
Has NASA been outside the Milky Way?
What is in the center of the Milky Way galaxy NASA?
Based on the immense gravity that would be required to explain the movement of stars and the energy expelled, the astronomers conclude that the center of the Milky Way is a supermassive black hole.
Is UY Scuti located in Milky Way?
About UY Scuti The star lies near the center of the Milky Way, roughly 9,500 light-years away from Earth. Located within the constellation Scutum, UY Scuti is a hypergiant star.
Are there any constellations in the Milky Way?
As viewed from Earth, the visible region of the Milky Way’s galactic plane occupies an area of the sky that includes 30 constellations.
What is the closest star to the Milky Way?
The closest it came to Sagitta- rius A* was about 17 light hours (more than 10,000 million kilometres). The stars’ orbits are the most convincing evidence yet that a supermassive black hole is hiding in Sagittarius A*.
