milky way versus andromeda as seen from earth
Bookmarked 717 weeks ago
from hubblecast scientists have been using hubble observations to predict the future of the andromeda galaxy and the milky way and how the collision will look from earth projecting the motion of andromeda039s stars over the next 8 billion years the astronomers now know the path that galaxy is taking through space and it039s heading straight for us computer simulations based on hubble observations show how the two galaxies will crash together in around 4 billion years039 timethe andromeda galaxy some 22 million light-years away is the closest spiral galaxy to our home the milky way for around a century astronomers have known it is moving towards us but whether or not the two galaxies would actually collide or simply fly past each other remained unclear now a team of astronomers has used the hubble space telescope to shed light on this question by looking at the motion stars in the andromeda galaxywe wanted to figure out how andromeda was moving through space so in order to do that we measured the location of the andromeda stars relative to the background galaxies in 2002 they were in one place and in 2010 they were in a slightly different place and that allowed us to measure the motion over a period of eight yearsthe motion is actually incredibly subtle and not obvious to the human eye even when looking at hubble039s sharp images however sophisticated image analysis revealed tiny movements that the scientists were able to project into the futurebased on these findings it is finally possible to show what will happen to the milky way over the next eight billion years as the galaxies drift closer then collide and gradually merge into a single larger elliptical galaxy with reddish stars and yet the solar system should in fact survive this huge crashthe reason we think that our solar system will not be much affected by this collision between the milky way and andromeda is that galaxies are mostly empty spaceeven though our galaxy as well as the andromeda galaxy has a hundred billion stars in it they are very far apart so if two galaxies actually collide with each other the stars basically pass right between each other and the chance of two stars directly hitting each other is really really small so the likelihood that our solar system will be directly impacted by another star for example in andromeda as we collide with it is really really smallwell if life is still present on earth when this happens the changes in the sky will be quite spectacular now they will be very very slow because the timescales on the scales of galaxies in the universe are very very long so you have to think millions of years but even then over these timescales over millions of years we will see big changes if we wait a few billion years andromeda will be huge on the sky it will be as big as our milky way because we039ll be very close to it and then later when the galaxies merge the merged remnant of the milky way galaxy and andromeda will look more like an elliptical galaxy and we039ll be sitting right in itso the view of the milky way on the night sky will be completely gone and this band of light will be replaced by a more spheroidal distribution of lightand so the sun born in the milky way almost 5 billion years ago will end its life in a new orbit as part of a new galaxy

i saw these kittens in a pet shop in the toronto area and just had to get the camera we were playing with them for a good 15 minutes i039d say i wish i039d have been able to get one as they were just so adorable they were all rescue kittens from a local shelter that was housing them at the pet shop so hopefully they039ll all go to good homesi039m not sure if from the video you can tell but they had this huge structure as their home and it felt a bit like big brother when i was going in with the camera it was funny to see how they were at first scared of it and then eventually started to warm up to it : i think they should totally do a pet edition of their show =adopt one of these kittens this video was shot at the following pet store on july 4th 2011pet value65 kingston road unit 8bajax on l1s 7j4phone: 905 239-4459outer tube: raleigh outer banks youtube gatheringaugust 26th to september 4th - details:http:wwwyoutubecomwatchv=sdu2byd_kxmhttp:wwwfacebookcomeventphpeid=154472651284003track your youtube statshttp:socialbladecomyoutubelike me on facebookhttp:facebookcomheyurgofollow me on twitterhttp:twittercomurgosubscribe to me on youtubeyou039re already here just hit subscribe :check out my second channel for close to daily clipshttp:youtubecomurgosclips
