What are white dwarfs? (Astronomy)

White dwarfs are dead stars that continue to glow because of heat, not nuclear fusion. Most stars in our universe will end up as a white dwarf star. Join us to learn how white dwarfs are made, what they’re like, how long they’ll shine, and how astronomers detect them. ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ We highly recommend the Astronomy textbook “Universe” by Roger Freedman et al: Universe 9th Edition http://amzn.to/2so6Ums Universe 10th Edition http://amzn.to/2tfBjUe Shop Amazon Used Textbooks - Save up to 90% http://amzn.to/2pllk4B ⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫⧫ Be sure to subscribe so you don't miss videos from Socratica! http://bit.ly/1ixuu9W And please share with all your friends!

What are Eclipses? || Solar Eclipse || Lunar Eclipse || Astronomy

★★★VERY IMPORTANT SAFETY NOTE★★★ Many fake eclipse glasses have been sold on Amazon.com Please read these articles and be safe! https://eclipse.aas.org/eye-safety/iso-certification Here is an approved list of vendors: https://eclipse.aas.org/resources/solar-filters What is an Eclipse? You may be a little confused about the difference between a Solar Eclipse and a Lunar Eclipse. You know an Eclipse has something to do with the Earth getting in the way of the Moon -- or, is it the Moon getting in the way of the Sun? Which is for a Solar Eclipse, and which is for a Lunar Eclipse? In this video, we’ll take a closer look. ★★★VERY IMPORTANT SAFETY NOTE★★★ You cannot watch a Solar Eclipse without protective ECLIPSE GLASSES. The key is to make sure they are ISO and CE certified. You should not be able to see ANYTHING other than the Sun. https://eclipse.aas.org/eye-safety/iso-certification Here is an approved list of vendors: https://eclipse.aas.org/resources/solar-filters ★★★ We thank our friends at solareclipseshield.com for sponsoring this video! ★★★ We dedicate this video to our wonderful friend and VIP Patron, Tracy Karin Prell. Tracy works tirelessly to promote astronomy awareness. We’ll be thinking of you, Tracy, when totality arrives on August 21, 2017 for the Total Solar Eclipse in the United States! ★★★★★★★★★★ Sometimes, the Sun, the Earth, and the Moon all line up along a straight line. When the Earth is in the middle, the shadow of the Earth can fall on the Moon, which is a Lunar Eclipse. OR, in the other arrangement, with the Moon in the middle, the shadow of the Moon can fall on the Earth, which is a Solar Eclipse. Notice that these Eclipses only happen during a New Moon (in the case of a Solar Eclipse) or a Full Moon (in the case of a Lunar Eclipse). But why don’t these happen every single month? You know that the Moon orbits the Earth, and the Earth orbits the Sun. But these orbits don’t take place in the same PLANE. There’s a difference of about 5 degrees between the plane of the Earth’s orbit and the plane of the Moon’s orbit. The two orbital planes intersect along what we call the “Line of Nodes.” This line passes through the Earth. It’s only when the Sun, Earth, and Moon all line up juuust right along the line of nodes, that you get an eclipse. ★★★ Try some of our other astronomy videos!
