For several years, scientists have tried to explain why so many pairs of exoplanets have an odd configuration — their orbits seem to have been pushed...
Pure ice is blue because ice absorbs more red light than blue light. Most icebergs appear white or blue when floating in seawater, but since the early...
Observations by ESA’s Mars Express orbiter show evidence of an ancient planet-wide groundwater system on the Red Planet.
Mosaic of the Valles Marineris...
In a study published in the journal Scientific Reports, a duo of researchers at University College London, UK, analyzed data from 3,662 adults aged 50...
Humans and other mammals are limited to seeing a range of wavelengths of light called visible light, which includes the wavelengths of the rainbow. But...
A multinational team of researchers has successfully sequenced the genome of the Antarctic blackfin icefish (Chaenocephalus aceratus), opening a genetic...
A team of archaeologists led by Washington State University scientists has discovered an ancient tattoo tool in southeastern Utah. With a handle of skunkbush...
A stunning new image from the NASA/ESA Hubble Space Telescope captures an ongoing cosmic collision between two disk galaxies.
This Hubble image shows two...
Twins are traditionally classified as monozygotic (identical) or dizygotic (fraternal). Monozygotic twinning results in genetically identical individuals,...
NGC 3079, an edge-on spiral galaxy located about 67 million light-years from Earth, contains two ‘superbubbles.’ New observations from NASA’s Chandra...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have spotted streams of molecular gas orbiting around an invisible gravitational...
The remarkably complete fossil skeleton of a sea cow with large incisor tusks that lived approximately 20 million years ago (Miocene epoch) has been discovered...
Collisions between bodies in our Solar System produce impact craters on large objects at a rate that depends on the population of impacting small bodies....
Ultra-diffuse galaxies are a relatively new class of galaxies that were first discovered in 2015. They are as large as our Milky Way but have between 100...
Paleontologists in Arizona have identified microfossils of what are thought to be the oldest known frog relative in North America.
A Chinle frog, inside...
The presence of a new planet on the outskirts of the Solar System was proposed by Caltech astronomers Konstantin Batygin and Mike Brown in 2016 to explain...
In a series of three experiments, a team of psychologists from Lancaster University, the University of Central Lancashire and the University of Gävle...
Fairy circles are extremely ordered round patches of bare soil within arid grasslands. They are known from southwestern Africa around the Namib Desert...
Mars today is a cold, dry world, but it may not always have been so. Recent studies increasingly indicate that the planet once had a thicker, denser atmosphere...
19th and early 20th century postural reconstructions of Neanderthals, and particularly the extensive one of the partial skeleton of an elderly male Neanderthal...
