What would happen if the Milky Way was a quasar?
If the Milky Way were a quasar, it would be incredibly bright and emit vast amounts of energy due to the supermassive black hole at its center consuming huge amounts of matter. The high energy output would impact the surrounding galaxies and alter the dynamics of the entire universe.
How far is the closest irregular galaxy?
The closest irregular galaxy to us is the Large Magellanic Cloud, which is located around 163,000 light-years away from Earth. It is a satellite galaxy of the Milky Way and can be seen with the naked eye from the southern hemisphere.
What would happen if a 200000 light years wide spiral galaxy collided with the Milky Way?
Likely the two galaxies would become one. Though there is some speculation in all likelyhood some stars would be lost in the process.
Incedentally in 3-5 billion years the galaxy Andromeda may collide with the milky way and it is about that size (a little smaller). In all likelyhood whan that happens our star will probably be lost fly out into the universe or into another dwarf galaxy.
Whatever happens the two galaxies would take a different course through the universe depending on how much mass the colliding galaxy has. (if it is Andromeda it is likely that we will continue on the course that we are on now)
What do you mean by elliptical trajectory?
Any planet that orbits a star ( our sun for example ) has an orbital trajectory. This is due to gravity and the centripetal force. An elliptical trajectory is when that planet orbits the star in an ellipse rather than a circle. Ellipse = squashed circle.
How is the sun related to the milky way galaxy?
Well so you know how the earth revolves around the sun. and how other planets revolve around the sun? Well that all forms a galaxy and the scientists decided to name it the milky way, so all in all the sun is located in the Milky Way.
The Sun itself is also in orbit around the center of the Milky Way. Located in the outer Orion arm, the Sun is moving in the same general direction as the arm itself.
We can do a quick calculation using Newtonian gravity (which is sufficient here since we are far away from the black hole). We do need some data:
-The distance between the Sun and the centre of our Galaxy is 2.5 x 10^20 meters. Since the distance between the Earth and Sun is completely negligible at this scale we can use this as the distance between the Earth and the black hole.
-The mass of the Earth is about 6 x 10^24 kilograms.
-The mass of the central black hole is about 8 x 10^36 kilograms.
We can now use the following formula:
F = G * m_earth * m_black_hole / distance^2
Where G is some constant named the gravitational constant. If we use this formula we arise at a force of about 7.7 x 10^20 Newtons. This is the force the black hole exerts on the Earth, and it is also the force the Earth exerts on the black hole.
How do you catch a rainburn in monster galaxy?
To catch a Rainburn in Monster Galaxy, you need to explore the Coral Cave region. Rainburns can be found in the wild here and captured using your capture disc just like any other monster. Keep exploring the area until you encounter one and then try to capture it. Good luck!
We can calculate the mass of the Milky Way by analyzing our solar system's orbit around the center of the Milky Way. The only problem is, that orbit takes about 220 million years to complete, and human beings have been observing it for less than 200. So our calculations could be - probably are! - way off.
Why are large telescopes used to study distant galaxies and not small telescopes?
Large telescopes are used to study distant galaxies because they can gather more light, allowing for better resolution and the ability to detect fainter objects. Their larger size also grants them a greater light-gathering capacity, which is essential for observing objects that are billions of light-years away. Additionally, large telescopes offer higher sensitivity and better data collection capabilities, enabling astronomers to analyze and study distant galaxies in greater detail.
The fusion of hydrogen atoms into helium in a contracting cloud produces nuclear energy in the form of heat and light. This process releases a tremendous amount of energy, which powers the brightness of stars like the sun.
How far is center of milky way to earth in light years?
The milky way galaxy is roughly a disc shape the is around 1000 lightyears thick on average and 100,000 lightyears in diameter. Our solar system sits roughly 26,500 light years from the centre.
Why some elliptical galaxies are lens shaped where as others are quite spherical?
Very lens-shaped elliptical galaxies have a high amount of reddish stars. Hence both their shape (the "spiral arms" have pulled inward over time) and the color of the stars implies they are very old galaxies. Spherical galaxies - I'm not up enough on that topic, so I will leave that part of the answer to another.
Will a blue star live longer than the sun?
A blue star has much greater mass and thus the temperatures in the core are much greater. This means it will use up it's supply of hydrogen much faster than our Sun.
How does the galaxy affect the earth?
Fairly averagely- it's a spiral galaxy of the larger sort, revolving slowly anticlockwise and of medium age as galaxies go. Our neighbouring galaxies are somewhat closer together in distance to each other than is usual, not exactly forming a cluster but making 'near neighbours' in galactic terms. There are many galaxies in the Universe that are far larger and older than our own Milky way, but also many others that are younger and smaller. Generally speaking, the younger galaxies tend to be in closer proximity to each other than older ones.
What is really amazing, is that there are AT LEAST as many galaxies in the Universe as there are stars in our own galaxy- that's hundreds of millions!! Pretty cosmic stuff, eh?!
The galaxies move farther and farther apart as time stretches across the empty void which is our universe.
Astronomers can determine Earth's position within the Milky Way by studying the distribution of stars, gases, and dust in the galaxy. By understanding the structure of the Milky Way and analyzing the position of objects in the sky relative to Earth, astronomers can create accurate visualizations of our location in the galaxy, even though these images are not taken from a point outside of our solar system.
Older stars are generally towards the centre of a galaxy as they will be the first to accumulate around the galactic centre.
Because they are older, there is less "free" hydrogen, so new star formation will occur wherever, there is enough matter to form a new star. This generally is around the outer edges of a galaxy.
The universe is actually about 15 billion years old.
I'm not sure where you got the statistic that the Hubble Space Telescope can see 20 billion light years into space; I think you're off by a factor of three or so.
Do all stars belong to a galaxy or can a star exist without belonging to a galaxy?
All stars we currently know of are part of a galaxy. Stars are born within galaxies from clouds of gas and dust. If a star were to exist without belonging to a galaxy, it would likely be a result of very rare and extreme circumstances, such as being ejected from its parent galaxy due to a collision or interaction with another galaxy.
Is the solar system about halfway between the center of the Milky Way galaxy and its outer edge?
The solar system is the Milky Way galaxy, Earth, and all other planets and galaxies are the solar system.
Planets do not generate their own light. They appear to glow because they reflect sunlight off their surfaces. The amount of light reflected depends on the planet’s composition, size, and distance from the sun. This reflected light is what we see from Earth as the planet's glow.
Are there galaxies with no supermassive black holes?
It is currently believed that most, if not all, galaxies contain supermassive black holes at their centers. These black holes can vary in size, with some being relatively small and inactive. However, the presence of supermassive black holes in galaxies is a common feature in the universe.
Is metro l drago better than lightning l drago?
It depends on the specific traits you are looking for. Metro L Drago is known for its stamina and defense capabilities, while Lightning L Drago excels in attack power. So it ultimately comes down to your preferred battling style.
How does a spectrograph provide information about stars chemical composition?
A spectrograph breaks down the light from stars into its component colors or wavelengths. Each chemical element absorbs and emits light at specific wavelengths, creating a unique fingerprint called a spectral line. By analyzing the spectral lines in a star's light, scientists can determine its chemical composition.
What is galaxy pegasus's weakness?
Galaxy Pegasus's weakness is its low stamina and defense, which can make it vulnerable to attacks from opponents with higher endurance and defensive capabilities. Additionally, its wide wings can sometimes make it easier to target and destabilize during battles.
