what it took to collect these 54-million-year-old photons from a supermassive black holebecome a video lab member http:bitlyvideo-labthis is an updated version of a video we published in 2016 about the event horizon telescope an international collaboration to image a black hole for the first time in human history on april 10 2019 the team announced their results: they had successfully imaged the supermassive black hole in the center of the galaxy m87 which is nearly 54 million light-years away from us they were able to achieve unprecedented resolution using very long baseline interferometry which combines the observations of multiple radio telescopes across the globe the team wanted to find out whether einstein039s theory of general relativity holds up in the extreme environment of black holes and the results do in fact seem to be consistent with the predictions in the future we may see more and shaper images of black holes as the team targets smaller wavelengths of light and rec

nasa using quasars to measure the earth: a brief history of vlbi
Bookmarked 558 weeks ago
vlbi or very long baseline interferometry is a technique that uses multiple radio telescopes to very precisely measure the earth039s orientation it was originally invented back in the 1960s to take better pictures of quasars but scientists soon found out that if you threw the process in reverse you could measure how the ground beneath the telescopes moves around how long days really are and how the earth wobbles on its axis as it revolves around the sun learn more about vlbi herefor more information about nasa039s space geodesy project visit http:space-geodesynasagovthis video is presented in both stereoscopic 3d and standard 2d versionsthis video is public domain and can be downloaded at: http:svsgsfcnasagovgoto10964like our videos subscribe to nasa039s goddard shorts hd podcast:http:svsgsfcnasagovvisitunesf0004_indexhtmlor find nasa goddard space flight center on facebook:http:wwwfacebookcomnasagsfcor find us on twitter:http:twittercomnasagoddard

milky way versus andromeda as seen from earth
Bookmarked 718 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
