On Earth, amethysts can form when gas bubbles in lava cool under the right conditions. In space, a dying star with a mass similar to the Sun is capable of producing a structure on par with the appeal of these beautiful gems. As stars like the Sun run through their fuel, they cast off their outer layers and the core of the star shrinks. This is what astronomers call a planetary nebula. Using NASA's Chandra X-ray Observatory, astronomers have found a bubble of ultra-hot gas at the center of one of these expiring stars in our Galaxy called IC 4593. At a distance of about 7,800 light years from Earth, IC 4593 is the most distant planetary nebula yet detected with Chandra. This new image of IC 4593 has X-rays from Chandra in purple, invoking similarities to amethysts found in geodes around the globe. The plum-colored bubble detected by Chandra is from gas that has been heated to over a million degrees. These high temperatures were likely generated by material that blew away from the shrunken core of the star and crashed into gas that had previously been ejected by the star. Astronomers also found evidence for a point-like X-ray source at the center of IC 4593. This X-ray emission has higher energies than the bubble of hot gas. The point source could be from the star that discarded its outer layers to form the planetary nebula or it could be from a possible companion star in this system. The name planetary nebula is misleading because this class of objects has actually nothing to do with planets. Astronomers created this term about two centuries ago because they thought these objects looked like the disk of a planet through their small telescopes. Today we know that a planetary nebula is formed after the interior of a star with about the mass of the Sun contracts and its outer layers expand and cool. When our Sun nears its planetary nebula phase several billions of years from now, its outer layers could extend as far as the orbit of Venus.

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.

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 is one of the most studied red dwarfs because of its proximity to Earth, and its proper motion is the fastest recorded in the sky.

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?
