Evans/NRAO/CaltechPrior to its discovery, astronomers believed that the Sagittarius Dwarf Galaxy was the closest galactic formation to our own. - Image Credit: R. Ibata (Strasbourg Observatory, ULP) et al./2MASS/NASAThe Canis Major Dwarf Galaxy Dwarf Galaxy is believed to contain one billion stars in all, a relatively high-percentage of which are in the In addition to the dwarf galaxy itself, a long filament of stars is visible trailing behind it. - Image Credit: Casey Reed/NASAThe prevalence of M-class stars is what made the formation easy to detect. The main body of the galaxy is already extremely degraded, a process which will continue as it travels around and through our Galaxy.In time, the accretion process will likely culminate with the Canis Major Dwarf Galaxy merging entirely with the Milky Way, thus depositing its 1 billion stars to the 200 t0 400 billion that are already part of our galaxy.For more information, check out this article from the Astronomy Cast has some interesting episodes on the subject. In addition to our galaxy being part of the Illustration of the Canis Dwarf Galaxy and its associated tidal (shown in red) in relation to our Milky Way. The Milky Way became the size it is now by eating up other galaxies like Canis Major, and it continues to do so today. However, he is the most charming stranger of all time. It's bright enough in the night sky that it's visible to the naked eye in the Northern Hemisphere.Accrding to researchers,in about 4 billion years,the Milky Way will collide with its nearest neighbourhood,The Andromeda Galaxy and they will collide with each other at 70 miles/second.The Milky Way is just one of more than 100 billion galaxies in the universe but it's the one that we call home.
Milky Way is a spiral shaped galaxy that contains several hundred billion stars including our sun. In this blog,I would like to share any topic related to science.I also want to write news related to NASA and ISRO missions. - Image Credit: NASA/ESA/STScI/A.
As revealed by the 2 micron all-sky survey (2MASS), the densest collections of galactic dust can be seen tracing out our spiral arms. We live on a planet called Earth Which is a small planet in our solar system.Also this solar system is a small part of our Galaxy called "Milky Way".Not only our solar system,there are many stars,planets are the parts of this Milky Way.A Galaxy is a large group of stars,gas and dust bound together by gravity. Andromeda Galaxy is a spiral galaxy that is approximately 2.5 million light years from Earth. NGC 1851, NGC 1904, NGC 2298 and NGC 2808 – are thought to have been part of the Canis Major Dwarf Galaxy before its accretion. In 19th century William Shanks(25th January,1812-1882) managed to calculate the first 707 digits of pi by hand but unfortunately he made a mistake after 528th place.Read also: the constellation of Andromeda, which was named after the … These can be satellite galaxies of Milky Way, satellite galaxies of Andromeda and other major galaxies including Andromeda. It also has associated open clusters, which are thought to have formed as a result of the dwarf galaxy’s gravity perturbing material in the galactic disk and stimulating star formation.Images of a few examples of merging galaxies taken by the Hubble Space Telescope. Our Galaxy is called Milky Way because it appears as a Milky band of light in the sky when you see it in a really dark area.This is why our galaxy is called, Milky Way.The Andromeda Galaxy is about 2.5 mllion light years away from us.Despite the immense distance, Andromeda is the closest large galaxy to our Milky Way. In 1768,Johan Lambert(26th August,1728-25th September,1777)proved that the value of pi is an irrational number because it can't be written as a rational simple fraction. A German dutch mathematician,Ludolph Van Ceulen(28th January,1540-31th December,1610)spent most of his time calculating the first 36 digits of pi.This is known as "Ludophine number". At 70,000 light years from Earth, this galaxy was determined in 1994 to be closer to us than the All of that changed in 2003 when The Canis Major Dwarf Galaxy was From this data, astronomers were able to conduct a survey of 70% of the sky, detecting about 5,700 celestial sources of infrared radiation. However, they shine very brightly in the infrared, and appeared in great numbers.The discovery of this galaxy, and subsequent analysis of the stars associated with it, has provided some support for the current theory that galaxies may grow in size by swallowing their smaller neighbors.
We all are always very curious about time machines.How people lived billions of years ago today, or how people will live billions of years from now,how much better science would be and so on, how much better it would be if we knew all this!Of course we don't have a time machine but we do have a huge library,through which you can know your past, present and even future.The name of this library is Infrared astronomy takes advantage of advances in astronomy that see more of the Universe, since infrared light is not blocked by gas and dust to the same extent as visible light.Because of this technique, the astronomers were able to detect a very significant over-density of An artist depicts the incredibly powerful flare that erupted from the red dwarf star EV Lacertae.
