In the cold dark of the constellation Ophiuchus, a faint, wraithlike shell of gas is quietly advertising the fate that awaits ...

The Hubble community bids farewell to the soon-to-be decommissioned Wide Field and Planetary Camera 2 onboard NASA’s Hubble Space Telescope. In tribute to Hubble’s longest-running optical camera, ...

Oregon stargazers have plenty of reasons to look up throughout August – a month marked by meteor showers, planetary conjunctions, and even a visible nebula. A formation known as the "dumbbell 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 ...

(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 ...

A conception of the James Webb Space Telescope orbiting the sun 1 million miles from Earth. Credit: NASA GSFC / CIL / Adriana Manrique Gutierrez In death, there can be great beauty. Astronomers ...

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 ...

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 ...

Some 3,000 light years away, shimmering layers of gas formed an almost perfect sphere around the faintly glowing, burned-out core of a dead star. The result looks like a giant crystal ball floating in ...

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 ...

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 ...
