This is called \u2018radial velocity\u2019 and it is providing the third velocity dimension in the Gaia map of our galaxy. We can now see how the stars move over a large portion of the Milky Way\u2019s disc.<\/p>\n<p>Thanks to Gaia, we can clearly see that the stars on average do not rotate with circular motions around the centre of the galaxy. This is because our Milky Way is not symmetric around its axis. It is a \u2018barred\u2019 spiral galaxy, and the motions reveal the orientation of the central bar.<\/p>\n<p><a href=\"https:\/\/www.esa.int\/Science_Exploration\/Space_Science\/Gaia\/Gaia_sees_strange_stars_in_most_detailed_Milky_Way_survey_to_date\" target=\"_blank\" rel=\"nofollow noopener\">Read more<\/a><\/p>\n<p><a href=\"https:\/\/www.esa.int\/esatv\/Videos\/2022\/06\/Gaia_data_release_3_exploring_our_multi-dimensional_Milky_Way\" target=\"_top\" rel=\"nofollow noopener\">Access the related broadcast quality video material<\/a><\/p>\n<p>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/www.esa.int\/ESA_Multimedia\/Videos\/2022\/06\/The_asymmetric_Milky_Way_in_motion\" target=\"_blank\" rel=\"nofollow noopener\">The asymmetric Milky Way in motion<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: ESA Top Multimedia&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>ESA\u2019s Gaia data release 3 shows us the speed at which more than 30 million Milky Way stars move towards or away from us.
