The idea is that the Earth sits at the center of an area of the Milky Way with significantly lower mass density than should ...

Looking up at the night sky, it may seem our cosmic neighborhood is packed full of planets, stars and galaxies. But ...

Could it be that the nature of the universe is tricking us, merely because of our location? The ongoing “Hubble tension” the intransigent discrepancy between the universe’s local and cosmic expansion ...

Images of the cosmos, such as the James Webb Space Telescope’s deep space snapshot, make space look chock-full of stuff. In the grand scheme of things, it is, but all those stars, galaxies, planets, ...

KBC Void in an immense, comparatively empty region of space containing the Local Group, and a large part of the Laniakea Supercluster - 2,000 million ly diameter sphere with its center about 250 ...

This Local Void, as it's known, has been estimated to be between 146 and almost a billion light-years wide, which is unfathomably empty. And it seems to be getting bigger.

Like the negative space in painting, the Local Void is defined by the contours of other shapes -- the shape of the Milky Way and the profiles of its galactic neighbors. To more accurately define ...

Earth has been blasted by the second strongest ultrahigh-energy cosmic ray ever observed. While its origins remain unknown, astrophysicists are pointing the finger at the Local Void, a ...

A smoothed rendition of the structure surrounding the Local Void. Our Milky Way galaxy lies at the origin of the red-green-blue orientation arrows (each 200 million light years in length).

Could our location in space be skewing cosmic measurements? A new study suggests a giant void may explain the Hubble tension.
