A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of Earth-like exoplanets.

Above the atmosphere is space. It’s called that because it has far fewer molecules, with lots of empty space between them.

Astrophysicists say that there is a clear, unambiguous signal in the cosmos which could eliminate inflation as a possibility.

Black holes are the most extreme objects in the universe, packing so much mass into so little space that nothing can escape.

A NASA-funded rocket mission is headed to space to measure the global electric circuit underlying the northern lights.

The mystery of whether microbial alien life might inhabit Enceladus, one of Saturn's 83 moons, could be solved by an orbiting space probe.

For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star.

An Earth-like planet orbiting an M dwarf star discovery could cause a major shift in the search for life on other planets.

New measurements show that the light emitted by stars outside our galaxy is two to three times brighter than the light from known galaxies.

A new map of the universe displays for the first time the span of the entire known cosmos with pinpoint accuracy and sweeping beauty.

When Mars was a young planet, it was bombarded by ice asteroids delivering water and organic molecules necessary for life to emerge.

The black hole’s gravity, which exists in three dimensions, mathematically connects to the particles dancing above it, which exist in 2D.

An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all.

An unrecognized effect boosts or diminishes the Pacific cold tongue, likely impacting El Niño/La Niña events and North American weather

Have you ever wondered what it would be like to travel to outer space – and then keep going? What would you find?

Provides insight into the formation and evolution of asteroids, icy moons and Earth-like rocky planets in the early history of the universe.

A team of Canadian astronomers have used the James Webb Telescope (JWST) to identify the most distant globular clusters ever discovered.

The signal – known as the cosmic graviton background (CGB) – can be detected, although it will be a massive technical challenge.

Our universe could be the mirror image of an antimatter universe extending backwards in time before the Big Bang per physicists in Canada.

Physicist Enrico Rinaldi, has used quantum computing and computer learning to describe what is believed to be the interior of a black hole.
