NASA's Hubble Space Telescope captured an uncommon sight—the death of a low-mass star—in this image of the Calabash Nebula ...

Planetary nebulae represent a brief, yet illuminating, phase in the evolution of low- to intermediate-mass stars. These glowing shells of ionised gas are shed in the late stages of stellar development ...

The Butterfly Nebula is changing, and astronomers are puzzled as to why these changes are occurring. Observations of this planetary nebula show dramatic changes in the butterfly’s ‘wings’ in just 11 ...

A way of estimating more accurate distances to the thousands of so-called planetary nebulae dispersed across our galaxy has been announced. The announcement was made by a team of three astronomers ...

(Please attempt/guess/answer the poll before reading the 'spoilered' calculations.) A question I've pondered, on occasion, is how much "mass" is in a 'planetary nebula' (the kind of nebula 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 ...

The article details various types of deep-sky objects observable by amateur astronomers, including double stars, variable stars, open and globular star clusters, emission, planetary, and reflection ...

Planetary nebulae (PNe) are the final stages of evolution of low-to-intermediate mass stars. They are expanding shells of gas and dust that have been ejected from a star during the process of its ...

A team of scientists in Australia and the United States, led by Associate Professor Miroslav Filipovic from the University of Western Sydney, have discovered a new class of object which they call ...
