Today on Crash Course Astronomy, Phil explains comets. Comets are chunks of ice and rock that orbit the Sun. When they get near the Sun the ice turns into gas, forming the long tail, and also releases dust that forms a different tail. We’ve visited comets up close and found them to be lumpy, with vents on the surface that release the gas as ice sublimates. Eons ago, comets (and asteroids) may have brought a lot of water to Earth -- as well as the ingredients for life.Check out the Crash Course Astronomy solar system poster here: http://store.dftba.com/products/crashcourse-astronomy-poster--Chapters:Introduction: Comets 00:00Comets = Dirty Snowballs 1:19Comets Have Two Tails 2:52Short-Term vs Long-Term Comets 4:35Where do comets come from? 5:06Comets Up-Close 6:17What Happens When Comets Hit Earth? 9:15Review 10:59--PBS Digital Studios: http://youtube.com/pbsdigitalstudiosFollow Phil on Twitter: https://twitter.com/badastronomerWant to find Crash Course elsewhere on the internet?Facebook - http://www.facebook.com/YouTubeCrashCourseTwitter - http://www.twitter.com/TheCrashCourseTumblr - http://thecrashcourse.tumblr.com Support CrashCourse on Patreon: http://www.patreon.com/crashcourse--PHOTOS/VIDEOSHalley's Comet, 1910 http://en.wikipedia.org/wiki/File:Halley%27s_Comet,_1910.JPG [credit: New York Times, Wikimedia Commons]Bayeux Tapestry http://upload.wikimedia.org/wikipedia/commons/f/fa/Bayeux_Tapestry_32-33_comet_Halley_Harold.jpg [credit: Wikimedia Commons]Comet McNaught [credit: Phil Plait]Comet McNaught + tail http://en.wikipedia.org/wiki/C/2006_P1#/media/File:Cometmcnaughtchrisn1.jpg [credit: Chris North, Wikimedia Commons]Comet surface http://rosetta.jpl.nasa.gov/sites/default/files/PIA18867-MAIN_Nov9-15765234852_c16c4097a5_o.jpg [credit: ESA/Rosetta/NAVCAM]Fine structure in the comet’s jets http://blogs.esa.int/rosetta/2015/01/16/fine-structure-in-the-comets-jets/ [credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA]Comet Halley http://apod.nasa.gov/apod/image/1001/halley_giotto_big.jpg [credit: Halley Multicolor Camera Team, Giotto Project, ESA]Comet McNaught https://solarsystem.nasa.gov/multimedia/display.cfm?Category=Planets&IM_ID=10194 [credit: ESO]Hubble's Last Look at Comet ISON Before Perihelion http://en.wikipedia.org/wiki/File:Hubble%27s_Last_Look_at_Comet_ISON_Before_Perihelion.jpg [credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)]Hale-Bopp: The Great Comet of 1997 http://apod.nasa.gov/apod/ap131013.html [credit: Jerry Lodriguss, used with permission]Sungrazer video http://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11307 [credit: NASA's Goddard Space Flight Center]“Large Web” graphic http://www.nasa.gov/sites/default/files/hs-2014-29-a-large_web.jpg [credit: JHUAPL/SwRI/Dan Durda]Comet Daniel http://commons.wikimedia.org/wiki/File:Comet_Daniel_-_1907.jpg [credit: Max Wolf, Wikimedia Commons]Vega 1 Low Res http://nssdc.gsfc.nasa.gov/planetary/image/veg2_tikf0002.gif [credit: Russian Academy of Sciences]The Nucleus of Comet Halley http://sci.esa.int/giotto/51183-the-nucleus-of-comet-halley/ [credit: ESA/MPS]Comet Hartley 2 http://en.wikipedia.org/wiki/103P/Hartley#/media/File:495296main_epoxi-1-full_full.jpg [credit: NASA/JPL-Caltech/UMD]Comet 67P/Churyumov-Gerasimenko http://sci.esa.int/rosetta/54472-comet-67p-on-3-august-2014/ [credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA]OSIRIS Catches Activity in the Act http://blogs.esa.int/rosetta/2015/04/20/osiris-catches-activity-in-the-act/ [credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA]Active Pit http://www.esa.int/spaceinimages/Images/2015/01/Active_pit [credit: ESA/Rosetta/MPS for OSIRIS Team MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA]Depiction of Philae‍‍ '​‍s planned touchdown on the comet http://en.wikipedia.org/wiki/Philae_ Learn more about your ad choices.

In which John Green teaches you about World War I and how it got started. Crash Course doesn't usually talk much about dates, but the way that things unfolded in July and August of 1914 is kind of important to understanding the Great War. You'll learn about Franz Ferdinand, Gavrilo Princip, the Black Hand, and why the Serbian nationalists wanted to kill the poor Archduke. You'll also learn who mobilized first and who exactly started the war. Sort of. Actually, there's no good answer to who started the war, but we give it a shot anyway.Crash Course is on Patreon!

Today, we'll learn about how women contributed to several organizations, including the Black Panthers. We'll also explore how the Black Arts Movement served as a way for women to empower Black People through creative output.Clint's book, How the Word is Passed is available now! https://bookshop.org/books/how-the-word-is-passed-a-reckoning-with-the-history-of-slavery-across-america/9780316492935 VIDEO SOURCES● Cheryl Clarke, “After Mecca”: Women Poets and the Black Arts Movement (New Brunswick, NJ: Rutgers University Press, 2004).● Ashley D.
