Planetary nebulae are colorful clouds of gas from dying stars. Brighter nebulae show more color due to intense light. Many planetary nebulae are visible even from suburban areas. Larger telescopes ...
Dark nebulae are important because they are star-forming regions containing organic molecules, some of which may be building blocks of life. Dark nebulae are found silhouetted against bright star ...
In their dying throes, some stars leave behind beautiful planetary nebulae — disk, spiral or even butterfly-shaped clouds of dust and gas (SN: 5/17/18). How these fantastically shaped clouds arise ...
NASA has shared 10 breathtaking images capturing the vibrant beauty of the cosmos, featuring colourful stars, glowing nebulae ...
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 ...
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 ...
NASA and ESA’s Hubble Space Telescope have recently released a breathtaking new image of NGC 2835, a spiral galaxy located 35 million light-years away in the constellation Hydra. This latest photo, ...
Compass needles? Astronomers have discovered something weird in the Milky Way's galactic bulge - a population of planetary nebula are all mysteriously pointing in the same direction. They noticed the ...
Astronomers often turn to NASA’s Hubble Space Telescope when they fancy observing any of the plethora of distant nebulae in outer space. Nebulae are astoundingly large accumulations of dust and gas, ...
The birth of the most massive stars -- those ten to a hundred times the mass of the Sun -- has posed an astrophysical riddle for decades. Massive stars are dense enough to fuse hydrogen while they're ...
