Human engineering appears to have moved the planet, literally. According to new research published this month, the global boom in dam construction over the past two centuries has caused measurable ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

Just as passengers don’t feel the plane’s speed while smoothly cruising, we don’t feel Earth’s movement because we’re ...

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

Scientists measure the distance to the Moon by bouncing lasers off mirrors placed there by space probes and astronauts.

Last Word is New Scientist’s long-running series in which readers give scientific answers to each other’s questions, ranging from the minutiae of everyday life to absurd astronomical hypotheticals. To ...

The answer, obviously, is really, really fast. Here, Universe Today‘s Fraser Cain tells us exactly how fast, and gives us answers to a few other things you may have wondered about before. For instance ...

The moon's gravity causes high and low tides, something known as the tidal force. As the tidal force shifts Earth's mass, it creates a tidal bulge on each side of the planet. As this happens, Earth ...

Here’s a reminder: We’re not the center of the Universe. As species, as members of this planet, this solar system or even the Milky Way galaxy. We are just a speck twisting in interstellar dust. Which ...
