Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Some stars are strange - No I mean literally! Made from strange quarks, these hypothetical objects could be hiding in plain sight, and could even be the missing dark matter we are looking for... but what exactly are they?

GW Orionis system observations by the Very Large Telescope and the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed that the stars "tear apart their planet-forming disc." according to the European Southern Observatory.

How many stars can you see in the night sky with your naked eye? A million? A Billion? As Carl Sagan liked to say, “Billions and billions?” On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are investigating how many stars you can really see. Neil explains why the number of stars you can see might be drastically lower than you think. Find out why the Moon poses a problem for seeing stars. Neil tells us how a full Moon can wash out a good amount of visible stars. Find out more about “dark time” and “bright time” when using telescopes. We discuss how binoculars can help you see a lot more stars. We dive into the evolutionary history of our eyesight. Also, Neil gives us a way to use your fist to calculate how many stars you can see in the sky. Lastly, discover more about how Andromeda went from being what we thought was a simple nebula to an entire other galaxy.

With more than half of all stars existing in binary orbits, it’s inevitable that many stellar remnants will end up in parasitic spirals with their partners. Today we’re going to look at the worst of these - from the novae produced by white dwarfs, to X-ray binaries created by neutron stars and black holes - and much weirder things besides.

As we become more experienced Observers, it is easy to become jaded by the stars. We use them as signposts and pointers to the “interesting” objects we have on our observing lists, and can begin to take the stars themselves for granted. It is only when we begin to understand stars and how important that they are, that we really begin to treat them as a significant part of our astronomy experience. Everything that you see in the night sky is visible to you because of light from a star. The stars themselves, nebulae, planets, moons, are visible because of starlight. Even dark nebulae are visible because they block the illumination of stars or other objects lit up by stars. Stars are born in clouds of cosmic gas and dust and provide light as a product of nuclear fusion. We exist because early generations of stars generated the elements that make up our planet and the chemical elements required for life. It is not an understatement to say that we exist because stars exist! As the author and coordinator of the Astronomical League Stellar Evolution program, Bill will explain the evolutionary paths of low and high mass stars. The League program guide includes a 27-page guide to stellar evolution, and a list of 100 objects to observe, many of which will be discussed in this fascinating presentation. Bio – Bill Pellerin was president of the Houston Astronomical Society in 2012-2013. As the author and coordinator of the ‘Stellar Evolution’ observing program for the Astronomical League. He has awarded 80 observers with a pin and certificate for completing the program (since 2013). He is the east Texas manager for the International Dark Sky Association, a member of the McDonald Observatory Board of Visitors and the American Association of Variable Star observers. He is currently active in observing R Crb type variable stars and reporting those observations to the AAVSO.

The constellation of Ophiuchus, which is represented as a serpent-bearer, contains a fascinating star called Barnard’s Star. It has a magnitude of 9.5 which renders it invisible to the unaided eye. In the past 100 years, scientists have collected fascinating data about this star, and have even discovered evidence of an exoplanet. Barnard’s star in one of the most studied red dwarfs because of its proximity to Earth, and its proper motion is the fastest recorded in the sky. 0:14 - Subscribe to Learn the Sky 0:38 - Intro to Barnard's Star 1:22 - Properties of Barnard's Star 2:55 - Proper Motion of Barnard's Star 3:28 - Barnard's Star b Planet 4:45 - Fast Facts about Barnard's Star 6:01 - Photo Attributes Photo Attributes: -Artist’s Conception of a planet orbiting a red dwarf star: By NASA, ESA and G.

Partial supernova blasts star across the Milky Way and we know about that thanks to NASA's Hubble Space Telescope. The star designated SDSS J1240+6710 managed to survive a “partial supernova” blasting itself out of its orbit with another star.

When the largest stars die, it’s usually pretty obvious. Supernovae are visible from billions of light-years away. But recently astronomers watched a massive star just disappear. No explosion, nothing, it just… vanished? Of course, it could have been dust. It’s always dust. But one intriguing possibility is that the star just imploded directly into a black hole, without the supernova detonation. And if that’s the case, is this happening more often, we just didn’t notice it? Want to see this video early?

Our solar system has just one star in it, the sun. But this is actually not the most common situation for systems. Most systems are multi-star systems, with binary systems being extremely common. These are systems where two stars orbit around their center of mass, and some of them even have planets. But we also know that stars come in so many varieties, due to their differing masses, and they leave behind different remnants. For this reason, there are a great many possible combinations of star types that produce different kinds of binary systems. What happens when you have a black hole and a main sequence star as a binary system? Or a pulsar and a red dwarf? How do the stars influence each others evolution? It's intense! Let's take a look.

Astronomers looking farther back in time than ever before are giving us a better idea of what the early universe must have been like, and we've identified another of the mysterious ultraluminous X-ray pulsars.

In general, a star’s size will determine its final destiny. Some stars fizzle out, while others explode, and what seals their fate may come down to a curious, cannibalistic process happening inside their cores!
