New NASA network poised to bring internet to entire solar system

NASA has made significant progress toward establishing a more reliable, and potentially solar-system-spanning communication system with the installation of a new breed of data network aboard the International Space Station. As its name suggests, the Delay/Disruption Tolerant Networking (DTN) service allows for the storage of partial pieces of information in the nodes along a communication path, which will allow for faster and more stable transmissions.Read More

DARPA seeks to develop command and control center for outer space

The area in the outer reaches of the Earth's atmosphere is a swarm of manmade objects, moving at tens of thousands of miles per hour and traversing a region hundreds of thousands of times larger than all of Earth's oceans combined. This complicates the operation of satellites for military use. DARPA has just announced its plans to come to grips with this chaotic region with the launch of a project aimed at revolutionizing the US military's command and control capabilities in space.Read More

Solar Impulse 2 takes flight for Europe

Solar Impulse 2 has taken off from New York on the next leg of its around the world journey, which will take the zero fuel aircraft across the Atlantic to Europe. The mission has already claimed 8 world records in an attempt to highlight the potential of green technologies that could help protect the environment from mankind's ever-increasing footprint.Read More

Violence detected: Sensors hit by second set of gravitational waves

Scientists making use of the twin Laser Interferometer Gravitational Wave Observatory (LIGO) instruments have announced the second confirmed detection of gravitational waves resulting from the collision of two black holes. Gravitational waves are ripples in the fabric of spacetime created by exceptionally violent cosmic events. The waves contain unique information unattainable by conventional telescopes, allowing scientists to gain a rare insight into one of the most energetic phenomena taking place in our Universe.Read More

Where have all the red giants gone?

Computer simulations carried out by researchers from the Georgia Institute of Technology may have discovered why older stars are suspiciously absent from the central region of our galaxy. Present day observations of the galactic center show it to be populated almost entirely by bright, young stars that are estimated to be only a few million years old, highlighting a startling lack of stellar diversity near the core of the Milky Way.Read More

Now you can listen to 13 billion year-old stars

A team of astrophysicists from the University of Birmingham has successfully used Kepler data to capture the sounds emitted by ancient stars. The study focused on eight red giant stars, the smallest of which is many times the mass of our Sun, and almost three times its current age.Read More

The Universe may be expanding much faster than we thought

New measurements carried out using the Hubble Space Telescope suggest that the Universe may be expanding up to 9 percent faster than previously believed. The team behind the study, which is the most accurate of its kind ever undertaken, believe that the culprit for the unexpected acceleration could be one of the invisible phenomena thought to comprise roughly 95 percent of the Universe.Read More

What do Pluto's heart and a lava lamp have in common?

Using data captured by NASA's New Horizons spacecraft, a team of researchers from Purdue University (PU) has estimated the depth of the vast nitrogen ice pool believed to exist beneath the Sputnik Planum region on the dwarf planet Pluto. Located in the dwarf planet's heart-shaped feature, the region is thought to continuously refresh its surface through a process known as convection.Read More
