The observations made from distant galaxies suggest that Dark energy exists.
This is because of the fact that the galaxies are moving away from each other.
This is given by Hubbles law.Instead of being attracted by the force of gravitation,galaxies tends to move away suggesting the presence of a gravity opposing force called dark energy.
Observations of distant galaxies show that they are moving away from us at an accelerating rate, implying the presence of a mysterious force counteracting gravity known as dark energy. This is supported by measurements of the cosmic microwave background radiation and the large-scale structure of the universe, which also confirm the existence of dark energy.

How does electromagnetic radiation from distant galaxies support the big bang theory?
Given by the fact that electromegnetic energy cannot be seen and how the radiation from distant galaxies supports the big bang theory? it can easily be said that...I dont know the answer. (0_0)
Quasars are thought to be the center of distant?
Quasars are thought to be the centers of distant galaxies where supermassive black holes are actively accreting matter. The intense energy emitted by this process makes quasars some of the brightest objects in the universe. Studying quasars can provide valuable insights into galaxy formation and evolution.
How does the energy of the cosmic microwave background compare to the energy radiated by all the stars and galaxies that ever existed?
The energy of the cosmic microwave background is about 400,000 times less than the energy of all the stars and galaxies that ever existed. The CMB is the remnant radiation from the early universe, while the energy radiated by stars and galaxies have been accumulating over millions of years.
Quasars are high-energy galaxies.?
More precisely, quasars are high-energy galaxy CORES, compact enough to appear starlike, yet emitting more radiation than a million "ordinary" galaxies.
What are two tools used in the big bang theory?
Two tools used in the Big Bang Theory are the telescope, which is used to observe distant galaxies and study the cosmic microwave background radiation, and the particle accelerator, which is used to recreate high-energy conditions similar to those that existed in the early universe.

What Major discoveries did the hubble telescope find?
The Hubble Space Telescope has made numerous major discoveries, including determining the rate of expansion of the universe, capturing detailed images of distant galaxies, and providing evidence for the existence of dark energy. It has also helped in studying exoplanets, black holes, and the formation of stars and galaxies.
What has the Hubble telescope contributed to our knowledge of astronomy?
The Hubble Space Telescope has provided detailed observations of distant galaxies, stars, and other astronomical objects, deepening our understanding of the universe's size, age, and composition. It has also helped to confirm the existence of dark matter and dark energy, as well as supported the study of exoplanets and the expansion of the universe.
The origin of energy in space?
Galaxies
Evidence that the universe is expanding is best provided by the?
redshift of light from distant galaxies, which indicates that they are moving away from us. This redshift is consistent with the idea that space itself is expanding, causing galaxies to move further apart from each other over time.
What have we found out by using the hubble?
The Hubble Space Telescope has provided valuable insights into the age and size of the universe, discovered new galaxies, and deepened our understanding of dark matter and dark energy. It has also allowed us to study the atmospheres of exoplanets and make groundbreaking observations of distant objects in the universe.
What is galaxies formation?
Galaxies formed from dust, matter, and energy that formed from the explosion of the universe.
What emits extremely large quantities of energy?
Quasars emit more energy than anything else in the universe. Quasars are massive black holes at the cores of some galaxies, swallowing matter and stars and ejecting them out collimated bipolar jets of matter and radiation which stretch out hundreds of thousands of light years. Since there are quasars in galaxies close by, these indicate the evolution of our universe.
The energy of light and other forms of radiation?
The energy of light and other forms of radiation is carried by packets of energy called photons. Different types of radiation have different amounts of energy depending on their wavelength or frequency. This energy can be absorbed by materials and converted into heat or other forms of energy.
How does the energy of the cosmic microwave background compare to the energy radiated by all the stars and galaxies that ever existed?
The energy of the cosmic microwave background is about 400,000 times less than the energy of all the stars and galaxies that ever existed. The CMB is the remnant radiation from the early universe, while the energy radiated by stars and galaxies have been accumulating over millions of years.
What is the evidence for dark energy?
The most direct evidence comes from supernovae observations in remote galaxies. Astronomers can use supernovas as 'standard candles' because the light we receive from them always follows the same pattern with time, allowing us to deduce how bright the supernova really is and by comparing it to how bright it appears on the sky, work out how far away it is. Light from distant galaxies is also red shifted by the expansion of the universe and the red shift tell us how far way (back in time) the galaxy is and the rate of the expansion of the universe. When astronomers calculate the expected amount of red shift for the supernovae based on how far away we know they are, they appear to be too strongly red shifted to account for the calculated expansion rate of the Universe. This means that the expansion of the universe is accelerating (which requires an energy to drive it). This energy is "dark energy". There is also other, indirect, evidence for dark energy.
