University of Cincinnati physicists, as part of an international research team, are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments.
NASA's TESS has completed its primary mission, imaging about 75% of the starry sky during a two-year-long survey. TESS has found 66 new planets, nearly 2,100 candidates, and much more.
Postdoc researcher Rafael Mesquita and a multi-institutional research team documented "surfer waves" in the upper atmosphere that create a pipeline of energy between layers in space.
Scientists have made a key discovery thanks to stardust found in meteorites, shedding light on the origin of crucial chemical elements.
Astronomers have applied artificial intelligence (AI) to ultra-wide field-of-view images of the distant Universe captured by the Subaru Telescope, and have achieved a very high accuracy for finding and classifying spiral galaxies in those images. This technique, in combination with citizen science, is expected to yield further discoveries in the future.
A new theoretical method paves the way to modelling the interior of the ice giants Uranus and Neptune, thanks to computer simulations on the water contained within them. The tool, developed by scientists from SISSA in Trieste and the University of California at Los Angeles, allows one to analyse thermal and electric processes occurring at physical conditions that are often impossible to reproduce experimentally, with a much easier and low-cost approach.
Helium is the second most abundant element in the universe after hydrogen. But scientists aren't sure just how much there actually is in the Sun's atmosphere. NASA's HERSCHEL sounding rocket has taken the first global measurements of helium in the extended solar atmosphere - a key piece of information for understanding our space environment.
Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth's atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life. This is the first time a total lunar eclipse was captured from a space telescope and the first time such an eclipse has been studied in ultraviolet wavelengths.
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state. This census helps researchers understand how and when a stellar embryo transforms to a baby star deep inside a gaseous egg. In addition, the team found a bipolar outflow, a pair of gas streams, that could be telltale evidence of a truly newborn star.
Taking advantage of a total lunar eclipse, Hubble used the Moon as a mirror to study sunlight that had passed through Earth's atmosphere. As a result, Hubble detected Earth's own brand of sunscreen - ozone - in our atmosphere. The technique simulates how scientists will search for evidence of life on planets around other stars.
