“Galactic archeology” makes spectacular find: the Milky Way is over 13 billion years old
Scientists have pushed the Milky Way's early history back more than 2 billion years: to less than 800 million years after the Big Bang.
Earth’s magnetic field supports biblical stories of destruction of ancient cities
By utilizing the ancient orientation of the Earth’s magnetic field, scientists have been able to piece together the history of ancient Judea.
Are we living in a baby universe that looks like a black hole to outside observers?
If the black holes that form in our cosmos give birth to baby Universes, perhaps we arose from the formation of a black hole ourselves.
Discovery finds the Earth’s core is constantly changing the length our day
The length of our day changes slightly over a six-year period. This recent discovery has perplexed scientists for about a decade.
Solar geoengineering could cool Earth, but some regions might continue warming
Some governments might try to “geoengineer” the planet by spraying substances into the upper atmosphere to reflect sunlight away from Earth.
A large solar storm could knock out the power grid and the internet
Typical amounts of solar particles hitting the earth’s magnetosphere can be beautiful, but too much could be catastrophic.
The cosmos can kill us in many ways. But the James Webb Space Telescope can help save us
Asteroid strikes, supernova explosions, and gamma-ray bursts are just a few of the ways the cosmos can kill us.
What happens if the Solar System’s largest comet collides with Earth?
The asteroid that caused the last mass extinction 65 million years ago was only 5 kilometers across — tiny compared to this one.
17 pictures that show how mind-bogglingly large the Universe is
Our entire planet is a little under 13,000 kilometers in diameter, or about seven orders of magnitude greater than the size of a human.

Kuwait wants to build 25,000 new houses on the site of a former tire graveyard. Here's how they're going to do it.
An asteroid could wipe out an entire city – here’s NASA’s plan to prevent catastrophe
Cosmic bodies, like asteroids and comets, are constantly zooming through space and often crash into our planet.
Online tree of life now connects 2.2 million living species
OneZoom is an interactive “tree of life” that lets you explore the evolutionary connections between more than two million species.
More than 5,000 tons of space dust hit Earth every year
We now know about how much space dust — micrometeorites that may have seeded Earth with the ingredients for life — hits the planet every year.
Light-driven levitation could lift probes to the edge of space
A new light-driven levitation technique can lift objects large enough to carry sensors to the understudied mesosphere near the edge of space.
How ‘mental time travel’ can lead us to sustainability
Bina Venkataraman, author of The Optimist's Telescope, believes that modern society’s shortsightedness is the root of many avoidable catastrophes.
Series | Guardians of the ApocalypseWill we ever predict earthquakes?
In 2010, an earthquake killed 222,570 people in Haiti, injuring 300,000 and displacing over a million. In an attempt to discover how to predict earthquakes, these researchers are using machine learning to analyze the acoustic data from tectonic plates.
The fleet of underwater drones probing Earth’s interior
The Earth’s interior may be the last wild frontier, but not for long. These underwater drones are scanning the ocean to create a 3D model of its internal dynamics.
