Geoengineering -- the deliberate effort to manipulate the Earth’s climate in an attempt to offset, delay, or slow global warming -- has slowly transformed from a pie-in-the-sky idea to a serious concept that may well be attempted one day. A wide variety of schemes have been proposed for how we might cool the Earth, but many of these would require the development of technologies far beyond our current capability.
Gravity is big and weird and difficult to study. It moves through space as a wave, sort of like how light does. But these waves are subtle and difficult to detect. They occur in measurable amounts only after massive events, like the collision of black holes.
NASA’s InSight mission has successfully landed on the red planet, making it the first Mars landing for the agency in six years. With the solar panels deployed, it’s time for the probe to start doing some science. Well, it’s going to do some science. InSight has to do several months of prep work before most of its instruments will be ready to relay data back to Earth.
A newly released composite photo of the galaxy cluster Abell 1033, which lies about 1.6 billion light-years from Earth, bears a striking resemblance to the Starship Enterprise from "Star Trek."
NASA’s spacecraft that landed on Mars Monday has beamed back its first clear photo of the desolate Red Planet. “There’s a quiet beauty here. Looking forward to exploring my new home,” NASA tweeted late Monday, hours after its new InSight lander touched down.
The writer Stewart Brand once wrote that “science is the only news.” While news headlines are dominated by politics, the economy, and gossip, it’s science and technology that underpin much of the advance of human welfare and the long-term progress of our civilization. This is reflected in an extraordinary growth in public investment in science. Today, there are more scientists, more funding for science, and more scientific papers published than ever before.
After a 300 million-mile, six-month interplanetary cruise, NASA’s Mars InSight robotic lander is heading for a plain-vanilla arrival at the Red Planet on Monday — and the team behind the mission couldn’t be more pleased.
In order to make accurate weather predictions, NOAA needs weather satellites in orbit to peer down at Earth. Until recently, the agency was making do with very old hardware from the 1990s, but it has since started launching the much improved GOES-R satellites. GOES-17 launched in March of this year, and it sent back a few images shortly after that.
Slow-motion collisions of tectonic plates under the ocean drag about three times more water down into the deep Earth than previously estimated, according to a first-of-its-kind seismic study that spans the Mariana Trench, a crescent-shaped trench in the Western Pacific that measures 1,500 miles long and is the deepest ocean trench in the world.
A convocation of delegates representing 60 countries voted today in Versailles to implement the most significant change to the International System of Units (SI) in more than 130 years. For the first time, all measurement units will be defined by natural phenomena rather than by physical artifacts.
