I asked my friend Julie Ménard how Earth formed. She’s a planetary scientist at Washington State University. She told me it started with the Big Bang. That was nearly 14 billion years ago. “The Big ...

How big would a telescope need to be to see Earth’s dinosaurs from 66 million light-years away? Think big—and then think ...

The earth and the heavens are connected to each other. The light and the heat, the blessings and the mercy in form of rain for instance, come down from the skies. According to the consensus of ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

We could go out with a crunch, and not a bang. Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean researchers suggests that dark ...

The search for the universe’s center starts with a simple intuition: if everything exploded outward in the Big Bang, there must be a point it all came from. Modern cosmology turns that intuition ...

Physicists suggest that a single, extraordinarily powerful cosmic signal detected on Earth could be linked to the explosive end of a tiny black hole from the early universe. That signal now stands as ...

The discovery is just the latest to come from the asteroid sample, which dates back to the dawn of the solar system.

The very first image of Earth from space was taken on October 24, 1946, from a German-made rocket launched from New Mexico. The U.S. seized the rocket at the end of World War II and studied its ...

Computer simulations suggest NASA’s Habitable Worlds Observatory could detect Earth-like exomoons around gas giant exoplanets through reflected starlight and lunar eclipses.

If you look across space with a telescope, you'll see countless galaxies, most of which host large central black holes, billions of stars and their attendant planets. The universe teems with huge, ...
