NASA scientists have strong evidence that Jupiter’s moon Europa has an internal ocean under its icy outer shell – an enormous body of salty water swirling around the moon’s rocky interior. New computer modeling suggests the water may actually be pushing the ice shell along, possibly speeding up and slowing down the rotation of the moon’s icy shell over time.
Scientists have known that…
Pi Day Challenge: Solve Stellar Math Problems With NASA
March 10, 2023
Pi Day is the annual tribute to the mathematical constant pi, whose infinite number of decimals is usually rounded to 3.14. So what better day to celebrate than March 14? To find pi, aka the Greek letter π, you simply divide any circle’s circumference by its diameter.
NASA and the Italian space agency Agenzia Spaziale Italiana (ASI) are partnering to build and launch the Multi-Angle Imager for Aerosols (MAIA) mission, an effort to investigate the health impacts of tiny airborne particles polluting some of the world’s most populous…
The NISAR Earth science mission has moved a step closer to its 2024 launch. Its science payload of two radar systems, one built by NASA and the other by the Indian Space Research Organisation (ISRO), recently completed the journey from NASA’s Jet Propulsion Laboratory in Southern California to ISRO’s U R Rao Satellite Centre in Bengaluru, India. Soon, teams at the facility will combine the…
A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries around the world. The pilot project offers a powerful new look at the carbon dioxide being emitted in these countries and how much of it is removed from the…
NASA’s Curiosity Views First ‘Sun Rays’ on Mars
March 7, 2023
Martian sunsets are uniquely moody, but NASA’s Curiosity rover captured one last month that stands out. As the Sun descended over the horizon on Feb. 2, rays of light illuminated a bank of clouds. These “sun rays” are also known as crepuscular rays, from the Latin word…
Quantum computers hold the promise of operating millions of times faster than conventional computers. But to communicate over long distances, quantum computers will need a dedicated quantum communications network.
To help form such a network, a device has been developed by scientists at NASA’s Jet Propulsion Laboratory and Caltech that can count huge numbers of single photons – quantum…
In the Origins and Habitability Lab at NASA’s Jet Propulsion Laboratory, you can find a world in a test tube – specifically, a simplified simulation of early Earth. By re-creating the conditions that would have been found on our planet roughly 4 billion years ago…
Earth and Venus are rocky planets of about the same size and rock chemistry, so they should be losing their internal heat to space at about the same rate. How Earth loses its heat is well known, but Venus’ heat flow mechanism has been a mystery. A study that uses…
NASA recently built two weather instruments to test the potential of small, low-cost sensors to do some of the work of bulkier, pricier satellites. Both instruments have exceeded expectations as trial runs, and they are already delivering useful forecast information for the most devastating of storms, tropical cyclones.
Launched in late 2021 to the International Space Station, COWVR (short for…
