Using NASA's SPHEREx space telescope, astronomers have observed remnants of the eruption of Nova Persei 1901. As a result, ...

Many good things come in threes: the Three Musketeers, the Three Tenors, movie and book trilogies, and more. There seems to be something symmetrical, beautiful, and satisfying when using the power of ...

Astronomers have employed the Australia Telescope Compact Array (ATCA) to investigate a peculiar pulsar wind nebula known as ...

Astroimaging involves a profound irony. While the goal of photography is to capture light, the majority of what astrophotographers capture in their images is utter darkness. Oh sure, the intended ...

NASA’s Hubble Space Telescope has produced the sharpest image ever taken of the Egg Nebula, a structure roughly 1,000 ...

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 ...

NASA, Donald Walter/South Carolina State University/Paul Scowen/ Brian Moore/Arizona State University A glimpse up at the night sky will reveal a seemingly endless landscape of twinkling stars, but ...

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 ...

Nebulae are made up of gas ― primarily hydrogen and helium ― and fine cosmic dust. These clouds are part of the interstellar medium of extremely low-density gas and dust that exists between stars in ...

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 ...

Emission nebulae are the subject of many of the most spectacular astrophotographs published in the last decade. Although there are many subcategories of nebulae, they all consist of interstellar gas ...
