how would the color of the elliptical change over the next several billion years

However, as new discoveries are made with the Hubble space telescope and other new technologies, these numbers may continue to be revised.
"Insect declines happen in a quiet way and we don't take notice from one year to the next." According to the standard cosmological model, the age of the universe is 13.7 billion years. In 4 billion years, the Milky Way (right) and Andromeda (left) will collide and merge. This means that a black hole already existed at most 500 million years … FIGURE 2.21— Galaxies might change their shapes long after their formation.In this computer-generated reenactment (a), two galaxies experience a close encounter over several hundred million years.

As shown, the smaller (red-colored) galaxy gravitationally disrupts the larger (blue) one, changing it … Figure 10.10 The onrushing water that carved out the outflow channels was responsible for forming these oddly shaped "islands" as the flow encountered obstacles--impact craters--in its path. However, here we find that, because of the nonlinear nature of the metallicity-to-color transformation, a coeval group of old clusters with a unimodal metallicity spread can exhibit color bimodality. 15. The colors of globular clusters in most large elliptical galaxies are bimodal. Figure 10.9 An outflow channel near the Martian equator bears witness to a catastrophic flood that occurred about 3 billion years ago. For reasons still unclear, many galaxies have a spiral shape when they initially form. Return. The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over time, and the processes that have generated the variety of structures observed in nearby galaxies. The most recent estimates put the age of the universe at between 13 and 20 billion years. The time span of 4.5 billion years is divided into smaller segments or units … Scientists estimate the age of the universe at 13.8 billion years based on the rate of expansion. It contains several hundred galaxies as they looked 3.5 billion years ago.
The way galaxies change over is that they sometimes change their rotation. Evidence of Earth’s Past. Earth is the third planet from the Sun and the only astronomical object known to harbor life.According to radiometric dating estimation and other evidence, Earth formed over 4.5 billion years ago. Yes, if these two galaxies collide, the end result will be an elliptical galaxy. "It's like going back to the place where you grew up.

This is generally taken as evidence for the presence of two cluster subpopulations that have different geneses.

18. Scientists use the geological time scale to describe Earth’s history from its formation to the present day. Because the deeper you look into space, the further you see back in time, we can conclude that galaxies several billions of light-years away formed fairly soon after the big bang. How big is the universe? The planet Earth is approximately 4.5 billion years old. Galaxy formation is hypothesized to occur from structure formation theories, as a … Yes, elliptical galaxies are formed from high density protogalactic clouds. The latest estimates say it is about 156 billion light years across. 17. 16. And the light of the quasar GB 1428, which arose due to the oldest supermassive black hole, took 13.2 billion years, only to reach the Earth. No, it takes a few million years to exhaust all the interstellar gas and dust in a starburst galaxy, not 10 billion years. "This may not sound like much, but in fact, it means 24 percent fewer insects in 30 years' time and 50 percent fewer over 75 years," said van Kink. Yet over the past several billion years, many galaxies in clusters have change form Spiral To a smooth, barren disk.
