Credit: Pixabay/CC0 Public Domain New research has revealed that the impact of one of the world’s most influential global climate patterns is much more far-reaching than originally thought. Scientists at the U.K.’s Meteorological Office have discovered that away from the tropics, the El Niño-Southern Oscillation (ENSO) has an additional impact on Atlantic weather patterns a…
This NASA/ESA Hubble Space Telescope image features the galaxy, NGC 4694. Credit: ESA/Hubble & NASA, D. Thilker This NASA/ESA Hubble Space Telescope image reveals the galaxy, NGC 4694. Most galaxies fall into one of two basic types. Spiral galaxies are young and energetic, filled with the gas needed to form new stars and sporting spiral…
Streams, rivers and lakes in cold regions contribute more to greenhouse gas emissions than previously thought. Credit: Annika Hollsten. Umea University Inland waters release substantial amounts of greenhouse gases, but this is rarely included in climate assessments. New research from Umeå University shows that not accounting for carbon fluxes between land and water systems leads…
Map of normalized channel steepness (ksn) as a reference for stream power. Credit: Nature Geoscience (2024). DOI: 10.1038/s41561-024-01535-w Mount Everest (also known as Chomolungma or Sagarmāthā) is famously the highest mountain in the Himalayas and indeed on Earth. But why? At 8,849 meters above sea level, Everest is around 250m taller than the other great…
Credit: Pixabay/CC0 Public Domain Enrico Fermi’s lunchtime question at wartime Los Alamos, “Where is everybody?” has been both a gift and a problem to scientists ever since. Known as “Fermi’s Paradox,” it simply asks, why, since life on Earth is ubiquitous and developed very early in Earth’s history, and the galaxy is very old and…
Complete radial velocity time series for HD 86728. The NEID data are shown as light (Run 1) and dark (Run 2) blue circles. Credit: Gupta et al., 2024. An international team of astronomers reports the discovery of a new extrasolar world orbiting a nearby star known as HD 86728. This is the first exoplanet detection…
Excavated in Canada, this Eastern red cedar log turned out to be remarkably well-preserved for its age: 3,775 years old. Credit: Mark Sherwood, University of Maryland A new study published in the journal Science suggests that an ordinary old log could help refine strategies to tackle climate change. A team of researchers led by University…
The newly-discovered GS-NDG-9422 galaxy appears as a faint blur in this James Webb Space Telescope NIRCam (Near-Infrared Camera) image. It could help astronomers better understand galaxy evolution in the early Universe. Credit: NASA, ESA, CSA, STScI, Alex Cameron (Oxford) The discovery of a “weird” and unprecedented galaxy in the early universe could “help us understand…
This multiwavelength image of the Cloverleaf ORC (odd radio circle) combines visible light observations from the DESI (Dark Energy Spectroscopic Instrument) Legacy Survey in white and yellow, X-rays from XMM-Newton in blue, and radio from ASKAP (the Australian Square Kilometer Array Pathfinder) in red.

Credit: Unsplash/CC0 Public Domain Utilizing one of the longest-running ecosystem experiments in the Arctic, a Colorado State University-led team of researchers has developed a better understanding of the interplay among plants, microbes and soil nutrients—findings that offer new insight into how critical carbon deposits may be released from thawing Arctic permafrost. Estimates suggest that Arctic…
