An artist’s impression of an active mantle plume – a large mass of hot, floating rock – rising from deep within Mars and pushing up Elysium Planitia, a plain in the planet’s northern lowlands. The volcanism at Elysium Planitia originates from the Cerberus Fossae, highlighted in red, a collection of young fissures that stretch more …

The data overwhelmingly confirms that rising greenhouse gas emissions are locking us into a scenario of destructive climate chaos, motivating scientists and corporations to invent ambitious carbon capture solutions. A Seafields Solutions concept seeks to make use of unlikely real estate by developing a giant seaweed farm in the middle of the Atlantic Ocean capable …

A newly weighed exoplanet has left astronomers deeply perplexed. After taking measurements on a very young, Jupiter-sized exoplanet named HD-114082b, scientists found that its properties don’t exactly match either of the two popular models of gas giant planet formation. In short, it is much too heavy for its age. “Compared to currently accepted models, HD-114082b …

A huge marine mammal once roamed the California coast, floating on the surface of the ocean and grazing on nothing but plants. It weighed twice as much as a hippopotamus and had such rough, scaly skin that it was compared to the bark of a tree. The extinct sea beast, called Steller’s sea cow, has …

CNN — A long time ago, gigantic sea turtles swam in the seas of the Earth. Until recently, these prehistoric giants, reaching lengths of over 3 meters (10 feet) from head to tail, were thought …
A computer-generated image showing a dark protostellar disk seen in profile at 90 degrees to the jets (orange) emanating from the poles of a young star. These disks are thought to be the precursors of planetary systems, with planets forming as the dust coalesces. RIKEN researchers may have spotted gas giant planet embryos in a …

Last week, the federal government revealed that cleaning up Yellowknife’s Giant Mine is now expected to cost $4.38 billion instead of $1 billion. This is, by a measure, higher than the estimated total revenues of the mine during its operation. Quantifying, in dollars, the impact of the mine on the local economy, the environment and …

An exotic dark matter model suggests that the first stars may have formed not as individuals, but as tiny pockets embedded in gigantic pancake-like sheets. This would have led to the formation of truly gigantic stars that the James Webb Space Telescope may be able to detect, according to a research team. Astronomers have a …
