The nebula of a dying star has a "inside-out" appearance, scientists announced in a new study — and this may be our sun's ultimate fate. Four years ago, astronomer Martín Guerrero from the ...

The NGC 2264 is a vast stellar complex located in the Monoceros constellation, about 2,600 light-years away. It includes two ...

Emission Nebulae Emission nebulae are so named because they emit their own light. This type of nebula forms when the intense radiation of stars within or near the nebula energizes the gas. A star’s ...

The name “planetary nebula” might indicate planets are somehow involved, when it is actually a reflection of the way these objects appear when viewed through a small telescope (like a planet, ...

As we continue to break new ground in the field of cosmology, the importance of carefully categorizing the objects we see comes into focus. Part of this stems from the fact that, increasingly, we find ...

HuBi 1 bucks the norm for a planetary nebula: its inner regions show emission from low-ionization potential species and its outer regions from high-ionization potential species. This unusual, inverted ...
