NASA explains how a lunar eclipse occurs and what skywatchers can expect. -- Supermoon Blood Moon Lunar Eclipse of 2019: Complete Guide: https://www.space.com/42830-supermoon-blood-moon-total-lunar-eclipse-2019.html Credit: NASA/GSFC

At the centre of every galaxy, there is a supermassive black hole (a million to a billion times bigger than the Sun). But how do we even know that? There are so many scientific results that have jigsaw-pieced together throughout the past century that allow us to know that now, so join me, as I go through decade by decade and explain the significance of all the results that have built up the big picture. My necklace is from here: https://lamenagerie.co/all-necklaces/ My sister made the frame in the background as a present when I passed my PhD: https://megansmethurstdesign.wordpress.com/work/ Please subscribe if you haven't already and click the little bell icon to be notified when I post a new video! For those of you that like specific decades here are the timestamps: 1900s - 0:53 1910s - 3:58 1920s - 5:50 1930s - 6:58 1940s - 09:04 1950s - 11:00 1960s - 12:09 1970s - 17:14 1980s - 18:38 1990s - 19:40 2000s - 22:12 2010s - 23:28 And for those of you who like reading straight from the source, here are links to all the papers I mentioned throughout the video, again listed by decade (note that "et al." is Latin for "and others"): Michell (1784) - https://royalsocietypublishing.org/doi/10.1098/rstl.1784.0008 Fath (1909) - http://articles.adsabs.harvard.edu/pdf/1909LicOB...5...71F Einstein (1915) - https://en.wikipedia.org/wiki/List_of_scientific_publications_by_Albert_Einstein#/media/File:GeneralRelativityTheoryManuscript.jpg Schwarzschild (1916) - https://commons.wikimedia.org/wiki/File:K._Schwarzschild_-_%C3%9Cber_das_Gravitationsfeld_eines_Massenpunktes_nach_der_Einsteinschen_Theorie_(1916).pdf Lemaître (1927) - http://articles.adsabs.harvard.edu/pdf/1927ASSB...47...49L Hubble (1929) - https://www.pnas.org/content/15/3/168 Einstein (1931; cosmological constant introduced) - http://echo.mpiwg-berlin.mpg.de/ECHOdocuView?url=/permanent/echo/einstein/sitzungsberichte/R583HGCS/index.meta&pn=1 Chandrasekhar (1931) - http://articles.adsabs.harvard.edu/pdf/1931ApJ....74...81C Tolman (1939) - https://journals.aps.org/pr/abstract/10.1103/PhysRev.55.364 Oppenheimer & Volkoff (1939) https://journals.aps.org/pr/abstract/10.1103/PhysRev.55.374 Seyfert (1943) - http://articles.adsabs.harvard.edu/pdf/1943ApJ....97...28S Bolton, Stanley & Slee (1949) - https://www.nature.com/articles/164101b0 Baade & Minkowski (1954) - http://articles.adsabs.harvard.edu/pdf/1954ApJ...119..206B Burbidge (1959) - http://articles.adsabs.harvard.edu/pdf/1959ApJ...129..849B Minkowski (1960) - http://articles.adsabs.harvard.edu/pdf/1960ApJ...132..908M Giacconi (1962) - https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.9.439 Hoyle & Fowler (1963) - http://articles.adsabs.harvard.edu/pdf/1963MNRAS.125..169H Schmidt (1963) - https://www.nature.com/articles/1971040a0 Kerr (1963) - https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.11.237 Salpeter (1964) - http://articles.adsabs.harvard.edu/pdf/1964ApJ...140..796S Zel’dovich (1964) - https://ntrs.nasa.gov/search.jsp?R=19640015209 Schmidt & Matthews (1964) - http://articles.adsabs.harvard.edu/pdf/1964ApJ...139..781S Schmidt (1965) - http://articles.adsabs.harvard.edu/pdf/1965ApJ...141....1S Penrose (1965) - https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.14.57 Hawking (1967) - https://www.jstor.org/stable/2415769?origin=ads&seq=1#metadata_info_tab_contents Hewish, Bell et al.

The more we fly the better we get. Safety and reliability are paramount. Our rigorous test program with New Shepard is putting the vehicle through the paces. We have successfully completed several crew capsule escape tests showing that our astronauts will be safe in any phase of flight. In addition to our test program, our payloads program is driving more flights of the system as we iterate on operations and technology in preparation for human spaceflight. All the learnings from the New Shepard program are being flowed into New Glenn development as we scale up our capabilities to serve the orbital market. Visit us at www.blueorigin.com to learn more.

But what if we could make our own stars at the places of our choosing? And can we merely mimic nature or create stars unlike anything which nature has formed?

Speaker: Scott Fleming of the Space Telescope Science Institute In April 2018, NASA’s Transiting Exoplanet Survey Satellite (TESS) launched and by the summer it was sending back data. What has this planet-hunter found? Dr. Scott Fleming will share several of the first exciting discoveries, plus detail about how the observatory is designed and how it compares to NASA’s Kepler/K2 mission. All of the data from TESS is available in the Barbara A. Mikulski Archive for Space Telescopes (MAST), which is based at the Space Telescope Science Institute. Host: Dr. Frank Summers Recorded live on Tuesday, January 15, 2019, at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A.

To explore some of the biggest questions in astronomy, ESA operates a fleet of space science missions that are exploring our Solar System and observing the Universe across the electromagnetic spectrum. In this video, Günther Hasinger, ESA Director of Science, reflects on current challenges in space science, from planets and life to the fundamental workings of the Universe. Then, María Santos-Lleo, XMM-Newton Science Operations Manager, explains how ESA's flagship X-ray observatory collects data from some of the most energetic sources in the cosmos. Finally, Bruno Merin, Head of the ESAC Science Data Centre, shows how data from ESA’s space science missions are stored and made available to the worldwide community.

Citizen scientists have discovered a planet that's potentially habitable

John Michael Godier discusses if there could be life on ice shell moons like Europa and Enceladus and the possibility of interstellar objects such as Oumuamua seeding life on other planets with Dr. Karen Meech of the University of Hawaii which discovered the first interstellar object Oumuamua, with the Pan-STARRS 1 telescope.
