Paleontologists have identified a new genus and species of algae called Protocodium sinense which predates the origin of land plants and modern animals and provides new insight into the early diversification of the plant kingdom.
Discovered at a site in China, this 541-million-year-old fossil is the first and oldest green alga from this era to be preserved in three dimensions, enabling the

In a speech that was as much an unofficial farewell as a proud update of the U.S. Space Force's youthful evolution, Chief of Space Operations, Gen. John "Jay" Raymond told an influential audience Sept. 20 that the service is on a strong footing and that it has deftly avoided two major traps.

China's manned space program, initiated 30 years ago, has grown more popular among Chinese people, who return with extensive support and a vision for space exploration.
On Sept. 21, 1992, China officially approved its manned space program, coded as "Project 921".
The first batch of Chinese astronauts were all recruited from elite pilots of China's air force. Among them were Yang Liwe

The search for extraterrestrial life just got more interesting as a team of scientists including Southwest Research Institute's Dr. Christopher Glein has discovered new evidence for a key building block for life in the subsurface ocean of Saturn's moon Enceladus. New modeling indicates that Enceladus's ocean should be relatively rich in dissolved phosphorus, an essential ingredient for life.

Coming into planning, we were ready for a standard "Touch and Go" plan, where we do some early morning science and then drive onto our next location. However, our workspace had some really great bedrock within arm reach, so we decided to convert the plan into a "Stay and Play" type of plan instead and spend more time characterizing the rocks here.

New research published in Earth and Planetary Science Letters suggests that Mars was born wet, with a dense atmosphere allowing warm-to-hot oceans for millions of years. To reach this conclusion, researchers developed the first model of the evolution of the Martian atmosphere that links the high temperatures associated with Mars's formation in a molten state through to the formation of the first

Lakes are bodies of water fed by rainfall, snowmelt, rivers and groundwater, through which, Earth is teeming with life. Lakes also contain critical geologic records of past climates.

Magnetic technology more typically found in your smartphone or computer hard drive has been flight-tested aboard a shoebox-sized satellite, employed to help monitor space weather in Earth orbit. The ‘magnetoresistive’ magnetometer design proven by ESA’s RadCube mission will now be flown on the Gateway station, set to orbit around the Moon.
