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
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.

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.
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.
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
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.
