Increased CO2 levels are greening the Earth

Researchers studying NASA satellite data on the Earth's vegetation coverage have discovered that plants have significantly increased their leaf cover over the last 35 years to the point that new growth across the planet is equivalent to an area twice as large as the continental United States. According to the study, the largest contributor to this greening is the growing level of carbon dioxide (CO2) in the atmosphere.Read More

Cassini image captures phantom rings

NASA's Cassini spacecraft has captured a stunning, and seemingly impossible view of Saturn's iconic ring system intersecting with a second set of phantom rings. The image was snapped using the probe's narrow-angle camera on Feb. 11, 2016.Read More

Planes, ships and ground stations working together to study pollution

Next week, an international effort between NASA and the Republic of Korea's National Institute of Environmental Research (NIER) will see the two bodies working together on an ambitious, six-week set of observations designed to improve our understanding of air pollution. The project will include the use of three planes housing 37 different instruments, and more than 300 ground sites, working together to gather data that help in the development of new solution to combat poor air quality across the globe.Read More

NASA taps Aerojet Rocketdyne for new space propulsion system

In anticipation of future deep-space missions, NASA has awarded a US$67 million, 36-month contract to Redmond, Washington-based Aerojet Rocketdyne to design and develop an Advanced Electric Propulsion System (AEPS). Based on previous ion thrusters like prototype NEXT and the Dawn mission to the asteroid Ceres, the new propulsion system could used to supply a future manned Mars mission.Read More

NASA puts nationwide traffic control system for drones to the test

If even half of the businesses hankering to get drones into US airspace are successful, the skies will soon be a whole lot busier than they are today. Looking to avert gridlock at altitude, NASA has been working on an air traffic management system for drones and today is carrying out its first coordinated testing, looking to see just how well it accommodates flights at different locations across the country.Read More

Fermi telescope helps close in on the origin of gravitational waves

Astrophysicists made history last year when they detected gravitational waves – the elusive ripples in space-time that were first theorized by Albert Einstein as part of his theory of general relativity in 1916. Early efforts failed to pinpoint the visible light component of the chaotic event that triggered the waves. But now data from NASA's Fermi telescope has reduced the search area by around two-thirds, which will help scientists understand more about the nature of the event and improve their systems for detecting future gravitational wave events.

Artist's impression: How to paint a planet

Exoplanets take many weird and wonderful forms, and we've only discovered a handful of the untold number that exist in our universe. Even though a small number have been directly imaged, most have been identified through indirect methods and in both cases, the actual appearance of the planet is left almost entirely to the imagination. This means that it falls to talented artists to provide an accessible interpretation of what these remote bodies could look like. We spoke to space artist Danielle Futselaar to uncover what goes into illustrating a planet.Read More

Cosmic spider shows clear signs of active star formation

Captured by the Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS), the Spider Nebula cuts a ghostly green figure in a new image release from NASA. The composite was captured in infrared light, a spectrum ordinarily invisible to the naked eye, though in this case common colors have been assigned to the different wavelengths allowing us to view the scene unaided.Read More
