About 550 light-years away in the constellation of Cassiopeia lies IC 63, a stunning and slightly eerie nebula. Also known as the ghost of Cassiopeia, IC 63 is being shaped by radiation from a nearby ...

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 ...

This week’s first small-telescope target is the Omega Nebula in Sagittarius. Also known as the Swan Nebula, the Horseshoe Nebula, and the Checkmark Nebula, this object was number 17 in the catalog ...

Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have observed a young planetary nebula known as IC 4997. Results of the observational campaign, presented in a paper ...

IC 418 is a planetary nebula. The nebula shows the life cycle of a star. A star emits light like Taeyang, and nuclear fusion reactions occur at its center. As time passes, the nuclear fusion reactions ...

SO much of the universe is beyond the naked eye. Reflection nebulae could have been yet another cosmic mystery, if it wasn’t for the neighbouring young stars that sets them apart. A reflection nebula ...

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process ...
