Why does outer space look black? ... "You would think that since there are billions of stars in our galaxy, ... a 2021 study in The Astrophysical Journal suggests that space may not be as black as ...

Our host galaxy, the Milky Way, is a barred spiral galaxy made of gas, dust and approximately 400 billion stars. From Earth it appears as a band of light in the night sky.

As the orbit shrinks, the pair of black holes in the PKS 2131-021 galaxy gets ever closer to colliding. This is only the second pair of black holes observed on the verge of merging.

Outer space may be cold and bleak and unspeakably huge, but at least it’s full of far-out objects with bonkers-sounding names like “blitzar,” “black dwarf,” and “dark energy star ...

The Hubble Space telescope of Nasa only takes photos in black and white. The scientists then add the colourising a technique developed around the turn of the 20th century that imitates how our ...

This could explain why Sgr A*, with its mass equivalent to around 4.5 million suns, has a spin speed between 0.84 and 0.96 but the rapidly feeding supermassive black hole at the heart of galaxy ...

The unusual circumstance of galaxy 2MASX J23453268−0449256 also has relevance to our galaxy. While the central supermassive black hole in the Milky Way, called Sagittarius A*, is much smaller ...

We’ve all seen beautiful images of outer space, with vivid swirls and bright stars resting on a black abyss. With how quick it is to snap a color photo on an iPhone, you might think that ...

A group of galaxies, including a large distorted ring-shaped galaxy known as the Cartwheel. NASA. While the Hubble Space Telescope (HST) has previously looked at the Cartwheel, dust obscured its view.

The black hole’s path through the gas and dust in the galaxy’s outer regions can compress some of that gas into new stars, too, which would also be visible (SN: 7/12/18).
