New Species of Bird Discovered on Lesser Sunda Islands
A team of scientists from the Swedish Museum of Natural History and elsewhere has described a new species of nightjar living in the tropical forests of Timor and Wetar, Lesser Sunda Islands. Male Caprimulgus ritae, Wetar, on October 13, 2014. Image credit: James Eaton. Nightjars are medium-sized nocturnal instectivorous birds in the family Caprimulgidae and
Snowball Earth’s Environmental Conditions Gave Multicellular Organisms Evolutionary Advantage
Fossil and molecular evidence suggests that complex multicellular organisms originated and proliferated during the Neoproterozoic Era (1,000-541 million years ago). Extreme glaciations during the Cryogenian period (720-635 million years ago), a phenomenon commonly referred to as Snowball Earth, led to a radical transformation of the Earth’s climate and oceans. New research suggests that Snowball Earth
Astronomers Observe Starburst Galaxy NGC 4449
Astronomers using the Gemini North telescope at the International Gemini Observatory have imaged NGC 4449, a prime example of starburst activity caused by ongoing mergers with nearby dwarf galaxies. This image, taken by the Gemini North telescope, one half of the International Gemini Observatory, shows the starburst galaxy NGC 4449. The image is being released
CERN Physicists Searching for Production of Elusive Higgs-Boson Pairs
Physicists from the ATLAS Collaboration at CERN’s Large Hadron Collider (LHC) have released the most sensitive search for di-Higgs production and self-coupling yet, achieved by combining five di-Higgs studies of LHC Run 2 data. An event display of a di-Higgs candidate event taken in 2017. Image credit: ATLAS Collaboration / CERN. Remember how difficult it
Webb Observes Intricate Structures in Ionosphere of Jupiter
Jupiter’s upper atmosphere is composed of a neutral thermosphere and charged ionosphere. Astronomers using the NASA/ESA/CSA James Webb Space Telescope have spotted unexpected small-scale intensity features such as arcs, bands and spots in Jupiter’s low-latitude ionosphere in the region above the Great Red Spot. This graphic shows the region observed by Webb: first its location
