Milky Way Of Galaxy Exploration

Milky way of Galaxy

We live in the Milky Way galaxy. Based on our observations, we have a barred spiral galaxy. While we may estimate the size of our galaxy, it is a bit harder to determine its age. We know that the Sun is roughly 5 billion years old. Depending on this observation of other stars in this Galaxy (via Hubble Telescope), we believe the Milky Way could be approximately 12-14 billion years old. The age was estimated by quantifying the quantity of beryllium in distant stars. The quantity of beryllium rises as a star gets older. Our barred spiral galaxy is about 100, 000 light-years across.


Whilst the stellar bar in the middle of the galaxy was discovered indirectly, the newest discoveries have proved its presence. The bar extends about one 3rd the diameter of the galaxy. The Solar System is roughly halfway between this edge of this leading bar and this edge of this galaxy. Neighbors And Travel - We're definitely not alone in our galaxy. There may be up to 400 billion stars and systems from the Milky Way. Our nearest neighbor is Proxima Centauri. Do not forget that our entire galaxy is 100, 000 light-years across. In this time, these Voyager spacecraft are this sole artificial objects to leave the Solar System.

Launched in 1977, they ought to get to this edge of this Solar System by the year 2015. At this pace, they'll need to travel another 82 million years before attaining the nearest star. As you can see, we're moving pretty slowly and visit another celebrity is not likely in our life. In The Scheme Of Things - Countless galaxies are on the market. Ours is impressive because it's ours. The closest galaxy is called the Sagittarius Dwarf. With lots of galaxies, systems, and planets, odds are good that we might something alive someplace.

Will we find super-smart aliens? Who knows. Most believe that there'll be some form of life, maybe microscopic. We are going to begin by exploring this planet of our Solar System first. Do not feel down.

 How many galaxies are there in the universe on a dark night the Milky Way?

The Milky Way galaxy is our cosmic home but it is far from being the only galaxy in the universe to get a better understanding of the composition and evolution of our universe astronomers try to answer a deceptively simple question how many galaxies are there in the universe on a dark night the Milky Way. It can be seen as a glowing band across the night sky and for a long time.

Hubble Telescope Discovery:-

 It was thought that the entire universe consisted of our galaxy alone this only changed in 1924 in the year that Edwin Hubble identified variable stars in several spiral nebulae. He used these stars to calculate the distances to these nebulae his

observations proved that these stars were far too distant to belong to our Milky Way. They instead were members of other galaxies far outside the Milky Way since then astronomers have tried to find out just how many galaxies there are in the observable universe a reliable first estimate could only be made after the Hubble Deep? Field was observed in 1995 this was the first real deep look into the universe and it revealed hundreds of galaxies that had never been seen before additional deep observations with Hubble and other instruments followed detecting even fainter and more distant galaxies from these observations astronomers determined that the universe contained a total of a hundred and twenty billion galaxies these are only the galaxies within the so-called observable universe this consists of all objects that can in principle be observed with telescopes like Hubble those from which light has had time to reach us since the beginning of the universe beyond this limit known as the cosmological horizon the universe.

continues just how far it goes is yet an unanswered question now astronomers have carried out a new analysis of published data from Hubble and other telescopes they have concluded that the previous estimate of the number of galaxies within the observable universe is at least 10 times too low they think that some 90% of the galaxies in the universe are actually too faint and too far away to be observed by the current generation of telescopes. Astronomers can only infer their existence based on models and calculations the newly collected data has allowed astronomers to look back more than 13 billion years into the past to the early days of the universe this look back unveiled an early universe in which the density of galaxies was also 10 times higher than today most of these galaxies were relatively small and faint with

masses similar to those of the satellite galaxies surrounding the Milky Way these results are powerful evidence that galaxies evolved and groovy emerges throughout the universe's history dramatically reducing their total number over time with 90% of the galaxies in our universe yet to be observed there is still much left to explore and to discover for Hubble as the upcoming James Webb Space Telescope. Once again Nature has surprised us beyond our wildest imagination you you now that you've caught up with Hubble make sure to get the latest from the ground too the isocost highlights the best of the European southern observatory and its powerful telescopes that observe from high in the Chilean Andes at the southern hemisphere's best-known sites for astronomical observations.
