Lakes and ponds are the final resting place for many of the Earth’s plants. Rivers collect much of the planet’s dead organic matter, transporting it to rest in calmer waters. But on a microscopic scale, lakes are anything but calm. An invisible metropolis of microbes feeds on these logs and leaves, producing greenhouse gases as

Highly porous material. Source: C. Hohmann/LMU Iridium is an ideal catalyst for the electrolytic production of hydrogen from water—but it is extremely expensive. But now a new kind of electrode made of highly porous material does an excellent job with just a hint of iridium. Today, the royal road to the effective electrolysis of water
Some of the largest exoplanets compared. Credit: NASA/ESA/Hubble Jupiter is the largest planet in the solar system. In terms of mass, Jupiter dwarfs the other planets. If you were to gather all the other planets together into a single mass, Jupiter would still be 2.5 times more massive. It is hard to understate just how

A popular energy solution is demand response (DR). Typically implemented in the industrial sector where energy use is high and peak energy demand comes at
The Alpha Centauri group is the closest star – or solar – system outside of our own at a distance of 4.3 lightyears, and it can be found in the night sky in the constellation Centaurus. The stars Alpha Centauri A and Alpha Centauri B comprise a binary system, in which the two stars orbit
Electricity supply is one of the biggest CO2 emitters globally. To keep global warming well below 2°C, several paths lead to zero emissions in the energy sector, and each has its potential environmental impacts — such as air and water pollution, land-use or water demand. Using a first-time combination of multiple modelling systems, an international

India will launch its cartography satellite Cartosat-3 and 13 commercial nanosatellites into sun-synchronous orbit on November 25, the Indian space agency said on Monday. According to the Indian Space Research Organisation (ISRO), its rocket Polar Satellite Launch Vehicle-XL variant (PSLV-XL) will put into orbit Cartosat-3 and 13 commercial nanosatellites from the US on November 25.
WASHINGTON — NASA announced Nov. 18 that it was adding five companies to a contract to perform commercial deliveries of payloads to the surface of the moon, a group that ranges from small ventures to Blue Origin and SpaceX. NASA said the five companies — Blue Origin, Ceres Robotics, Sierra Nevada Corporation (SNC), SpaceX and

The study of
WASHINGTON (Reuters) – Scientists on Monday unveiled the first global geological map of Saturn’s moon Titan including vast plains and dunes of frozen organic material and lakes of liquid methane, illuminating an exotic world considered a strong candidate in the search for life beyond Earth.

On the morning of April 25, 2018, in Fort Wayne, Indiana, Omarion Jordan came into the world ten-fingers-and-toes perfect. His mother, Kristin Simpson, brought her dark-haired newborn home to a mostly empty apartment in Kendallville, about 30 miles to the north. She’d just moved in and hadn’t had time to decorate. Her son, however, had
From time to time, a new picture of outer space changes our understanding of the universe and our place in it. One hundred years ago, astronomers captured the light of stars behind the sun during a total solar eclipse, proving that the sun had bent the starlight and validating Albert Einstein’s new theories of gravity.
BREMEN, Germany — FCC Chairman Ajit Pai informed Congress Nov. 18 that the agency will run a public auction of C-band spectrum instead of allowing a consortium of satellite operators to sell it directly to 5G wireless operators. Satellite operators Intelsat, SES and Telesat, acting as the C-Band Alliance, have been lobbying the Federal Communications
A Japanese space probe is heading home from an asteroid 250 million km (155 million miles) from Earth after collecting sub-surface samples that could help scientists seeking the origins of life, Japan’s space agency said on Monday. Asteroids are believed to have formed at the dawn of the solar system and scientists say the asteroid,
