Isotopic analysis of water trapped in volcanic glass in lunar samples show that the moon has more water than thought, and the water there and on Earth had the same origins. Karen Hopkin reports
We currently have a maximum of about 60 minutes to prepare for tech disruptions on Earth due to coronal mass ejections from the sun, but an improved forecasting system could lengthen that lead time by hours. Maria Temming reports
In this special edition of 60-Second Science Video, two numbers compete. Which is larger? The number of tiny LEGO bricks it would take to build the Great Pyramid or the number of trees on Earth?
When I was a kid, energy was fun. I used to write to utility companies asking for their brochures on nuclear power and then sit and study the cutaway diagrams of reactors.
To find out what water might look like on alien worlds, a group of researchers decided to see how Earth's oceans would appear from afar, as if from another planet.
Scientists confirm that a comet carved out Ontario's Sudbury Basin 1.8 billion years ago, forming the second largest impact crater on Earth
David Biello looks back at the big environmental stories of the year covered on 60-Second Earth
The emergence of the theory that the solar system coagulated from a vast cloud of dust has led to a new inquiry into the chemical history of our planet
NASA's Aqua satellite captured this image of southeastern Australia today—the smoke from the deadly wildfires there is plainly visible from Aqua's orbit 440 miles (705 kilometers) above Earth.
Astronomers have pinpointed where and when the most recent stellar explosions near Earth occurred, showing they could have impacted the development of life on our planet
Vote to unshackle clock time from its link to Sun is postponed to 2015
By measuring the temperature of dust circling nearby Sun-like stars, researchers conclude that rocky bodies are smashing into each other with the potential to aggregate into rocky planets. Steve Mirsky reports from the AAAS conference in Boston.
Fossilized corals, lasers beamed at a receding moon, Chinese artifacts, and other evidence have revealed that over the ages the length of time it takes Earth to spin once on its axis has increased significantly
Sandy particles seen circling around a young binary star system 2,400 light years from us could be an early stage in the formation of a new earth-like planet. Steve Mirsky reports.
The solar wind sweeps the earth's magnetic field into a vast tail. Disruptions of the tail generate bright auroras at the earth and propel great bodies of magnetized gas into interplanetary space
The Center of the Earth--What We Know of Its Temperature, Structure and Its Composition
Madagascar, an island nation in the Indian Ocean that is home to thousands of species found nowhere else on Earth, is captured in its entirety from space.
Comparing the DNA sequences of similarly shaped proteins in various organisms produces a geneaology of all life on earth that matches those created from completely different data sets. Steve Mirsky reports.
As is well known, the earth is a slightly flattened sphere, but it also departs from the spherical in other interesting ways. These departures have been most clearly revealed by the orbits of artificial satellites
