Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars, it is not expected to provide suitable conditions for the formation and hosting of a large planet.
The astronomical records of imperial China are some of the most comprehensive archives in the history of science, spanning over two millennia, from 221 BC to 1911 AD, and providing detailed insight into phenomena ranging ...
Trees get most of the love, but diatoms, a group of photosynthetic microalgae, produce 20% of Earth's oxygen and are the foundation of aquatic food webs. The prevalence and diversity of diatoms have made them highly successful, ...
Observations with the James Webb Space Telescope (JWST) have provided new clues about how the exoplanet WASP-121b has formed and where it might have originated in the disk of gas and dust around its star. These insights stem ...
As the focus on energy resiliency and competitiveness increases, the development of advanced materials for next-generation, commercial fusion reactors is gaining attention. A recent paper published in the journal Current ...
The job of a catalyst is to ultimately speed up reactions, which could reduce an hour-long process into several minutes. It has recently been shown that using external magnetic fields to modulate spin states of single-atom ...
Strontium titanate was once used as a diamond substitute in jewelry before less fragile alternatives emerged in the 1970s. Now, researchers have explored some of its more unusual properties, which might someday be useful ...
The goal of carbon dioxide (CO2) hydrogenation is to turn pollution into fuel. This process transforms CO2, one of the main greenhouse gases, into chemical products and renewable fuels. One important product is methanol, ...
New research brings together 7,000 years of history in South Arabia to show how ancient pastoralists changed placement and construction of monuments over time in the face of environmental and cultural forces.
The electrochemical CO2 reduction reaction (eCO2RR) to produce value-added multi-carbon (C2+) products, especially ethanol, represents an effective strategy for sustainable energy conversion and achieving carbon neutrality. ...
