We knew we’d see things previously thought impossible. And we just did - an object on the boundary between neutron stars and black holes, which promises to reveal the secrets of both.Hosted by Matt O'DowdWritten by Matt O'DowdGraphics by Leonardo Scholzer, Yago Ballarini, and Pedro OsinskiDirected by: Andrew KornhaberCamera Operator: Bahaar GholipourExecutive Producers: Eric Brown and Andrew KornhaberPrevious Episodes Referenced:Ligo’s First Detection of Gravitational Waves: https://www.youtube.com/watch?v=gw-i_VKd6WoThe Future of Gravitational Waves: https://www.youtube.com/watch?v=eJ2RNBAFLj0How to build a black hole https://www.youtube.com/watch?v=xx4562gesw0&vl=enStrange Stars - https://www.youtube.com/watch?v=u4RNGRyzt10Special Thanks to Our Patreon SupportersBig Bang SupportersRobert DoxtatorAhmad JodehCaed AldwychRadu NegulescuAlexander TamasMorgan HoughJuan BenetFabrice EapDavid NicklasQuasar SupportersAlec S-LChristina OegrenMark HeisingVinnie FalcoHypernova Supporterswilliam bryanJulian TyackeSyed AnsarJohn R.

April 25th of 2018 marks the beginning of just such a leap for much of astronomy. In the early hours of the morning, the Gaia mission’s second data release dropped. Our understanding of our own galaxy will never be the same again.You can further support us on Patreon at https://www.patreon.com/pbsspacetimeGet your own Space Time t­-shirt at http://bit.ly/1QlzoBiTweet at us! @pbsspacetimeFacebook: facebook.com/pbsspacetimeEmail us! pbsspacetime [at] gmail [dot] comComment on Reddit: http://www.reddit.com/r/pbsspacetimeHelp translate our videos!https://www.youtube.com/timedtext_cs_panel?tab=2&c=UC7_gcs09iThXybpVgjHZ_7gPrevious Episode:The Star at the End of Timehttps://www.youtube.com/watch?v=-iWGtQ03OZMThe Gaia satellite was launched in late 2013, entirely built and operated by the European Space Agency. It’s primary goal is to map the stars of the Milky Way with a scale and precision orders of magnitude greater than ever before. Gaia’s predecessor, Hipparcos, catalogued 120 thousand stars, Gaia blows it out of the water with positions, colors and brightnesses of nearly 1.7 billion stars. Gaia can see orders of magnitude fainter and further away than previous missions. But its greatest superpower is its precise astrometry – Gaia can pin down a star’s position to the equivalent of a human hair’s width at 1000 km. That’s one-to-two thousand times smaller than the resolution of the Hubble Space Telescope.
