Distance

Wearing face masks and maintaining social distances were a significant part of the world's reaction to the COVID-19 pandemic. Now, new research says the practices are not only effective at saving human lives, but chimp lives as well.

Astronomers have discovered the most distant – and therefore earliest – known black hole. Hiding in a galaxy called GN-z11, this black hole is bigger than should be possible given the age of the universe.

For the first time in 30 years, new terms have been officially added to the International System of Units. The four new prefixes – ronna, quetta, ronto and quecto – describe very large and very small numbers that until now didn’t have their own names

An international team of astronomers has detected the most distant radio galaxy ever observed. By measuring the redshift of its light, the researchers determined that the object is about 12 billion light-years away, which dates it back to when the universe itself was just a kid.

The full moon has long been associated with lunacy, violence, fertility, disasters, and the performance of the stock market. While these have been thoroughly debunked, a lunar ranging study has long contended with a "Full-Moon Curse." This Curse is real, and has now been explained.

Astronomers have used eight eclipsing binary stars in the Large Magellanic Cloud to accurately determine its distance from the Earth.

Is reality a 3D hologram of a 2D universe? This is a question that a team of researchers at the US Department of Energy's Fermilab are asking.
