Using data from the MUSE instrument, researchers at the Leibniz Institute for Astrophysics Potsdam (AIP) succeeded in detecting extremely faint planetary nebulae in distant galaxies. The method used, ...

When choosing an astronomical telescope, it is easy to think that "the higher the magnification, the larger distant stars ...

Many good things come in threes: the Three Musketeers, the Three Tenors, movie and book trilogies, and more. There seems to be something symmetrical, beautiful, and satisfying when using the power of ...

Images of two iconic planetary nebulae taken by the Hubble Space Telescope are revealing new information about how they develop their dramatic features. Researchers from Rochester Institute of ...

Colors of the Universe explores the natural colors found in space, from red, green, blue, black, orange, purple, pink, white, and yellow to the stars, planets, and nebulae that create them. The video ...

Something is amiss in the Butterfly Nebula. When astronomers compared two exposures of this planetary nebula that had been taken by the Hubble Space Telescope in 2009 and 2020, they saw dramatic ...

About 7.5 billion years from now, our sun will have converted most of its hydrogen fuel into helium through fusion, and then burned most of that helium into carbon and oxygen. It will have swollen to ...

“Ghost stars,” or planetary nebulae, are some of the most beautiful objects in the cosmos. Formed when a red giant star burns through its nuclear fuel and sheds its outer layers, the nebulae (which ...

Planetary nebulae are the remnants of stars roughly one-to-eight times the size of the sun surrounded by hot gas lit up by ultraviolet radiation. Kastner hopes that through a comprehensive campaign of ...

When a star runs out of fuel, it sheds its outer layers of gas and, if it doesn't explode in a supernova, forms a glowing shell of ionized gas that expands into space. Shells like these are known as ...
