In the most precise experiment to date, researchers confirm a principle of Einstein’s Theory of General Relativity

Albert Einstein arrived in New York on the SS Rotterdam IV; crowds of people awaited his arrival in the States.

One Hundred Years Ago, Einstein Was Given a Hero's Welcome by America's Jews

The German physicist toured the nation as a fundraiser for Zionist causes, even though he was personally torn on the topic of a Jewish nation

Einsteinium was first created in 1952 in the aftermath of the first hydrogen bomb test on the island of Elugelab, which is now a part of the Enewetak Atoll in the Marshall Islands, located in the Pacific Ocean.

Scientists Take Fundamental Measurements of Einsteinium for the First Time

An artist’s rendering of the mysterious object, which has a mass about 2.6 times that of the sun and was consumed by a black hole some 23 times the mass of the sun. Astronomers say it's less massive than any known black hole and more massive than any known collapsed star, called a neutron star.

Distant Black Hole Collides With a Mysterious Object

Scientists detect what is either the heaviest known neutron star or the least massive black hole ever recorded

After two eclipse expeditions confirmed Einstein's theory of general relativity, the scientist became an international celebrity.

One Hundred Years Ago, Einstein's Theory of General Relativity Baffled the Press and the Public

Few people claimed to fully understand it, but the esoteric theory still managed to spark the public's imagination

An artist's visualization of the star S0-2 as it passes by the supermassive black hole at the galactic center. As the star gets closer to the supermassive black hole, it experiences a gravitational redshift that is predicted by Einstein's general relativity. By observing this redshift, we can test Einstein's theory of gravity.

A Star Orbiting in the Extreme Gravity of a Black Hole Validates General Relativity

The star S0-2 gets so close to the supermassive black hole at the center of the galaxy that it can be used to test our fundamental understanding of gravity

As the 2017 North American total solar eclipse comes to an end, the famous "diamond ring" becomes visible. The sun's corona is also visible, with the star Regulus to the left.

A Total Solar Eclipse 100 Years Ago Proved Einstein’s General Relativity

Two teams of astronomers voyaged to Africa and Brazil to observe the most famous eclipse in science

Why Everyone Went on a Wild Goose Chase Looking for the Planet Vulcan

The idea of a ninth planet in the Solar System would resolve a mathematical conundrum about Mercury–only problem is, it wasn't there

An artist's rendering of a star colliding with the surface of a supermassive sphere. In recent years some scientists have surmised that black holes may be hard objects rather than a region of intense gravity and compressed matter.

Could You Crash Into a Black Hole?

Probably not, but it’s fun to think about
