Scientists from Samara University and several universities in the USA have proposed and experimentally confirmed new fundamental chemical mechanisms for the synthesis of polycyclic aromatic hydrocarbons (PAHs). The results of this work are presented in the article published in Oct. 8 edition of the scientific journal Nature Astronomy. The described processes make it possible to understand how complex molecules that are related to the origin of life in the universe are formed.
New research by a team led by an astrophysicist at the University of Warwick has a way of finally telling whether newly forming planets are migrating within the disc of dust and gas that typically surrounds stars or whether they are simply staying put in the same orbit around the star.
With scarce nutrients and weak gravity, growing potatoes on the Moon or on other planets seems unimaginable. But the plant hormone strigolactone could make it possible, plant biologists from the University of Zurich have shown. The hormone supports the symbiosis between fungi and plant roots, thus encouraging plants' growth -- even under the challenging conditions found in space.
Evgenij Zubko of Far Eastern Federal University (FEFU) in collaboration with other team members has developed a comprehensive model to explain the results of a photometric study of the Comet Schwassmann-Wachmann 1 (29P) which was successfully accomplished recently. The findings came as a real surprise revealed that the dust environment of 29P predominantly consists of only one type of material -- magnesium-rich silicate particles with presumably a small amount of iron (Fe-Mg silicates).
The moon may be the key to unlocking how the first stars and galaxies shaped the early universe. A team of astronomers led by Dr, Benjamin McKinley at Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) and the ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D) observed the moon with a radio telescope to help search for the faint signal from hydrogen atoms in the infant universe.
Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new record for the most extreme range of orbits yet observed: the outermost planet is more than a thousand times further from the star than the innermost one, which raises interesting questions about how such a system might have formed.
Ever since Chris Fox was a young boy, he wanted to visit alien planets. With no immediate plans for such a voyage, the Western University graduate student has done the next best thing. He's gone and found one.
In an unprecedented study of a solar eclipse's influence on bee behavior, researchers at the University of Missouri organized citizen scientists and elementary school classrooms to set up acoustic monitoring stations to listen in on bees' buzzing -- or lack thereof -- as the August 2017 total solar eclipse passed over North America. The results were clear and consistent at locations across the United States: Bees stopped flying during the period of total solar eclipse.
A recently published study led by researchers at the University of Hawai'i at Manoa School of Ocean and Earth Science and Technology reveals Ganymede, an icy moon of Jupiter, appears to have undergone complex periods of geologic activity, specifically strike-slip tectonism, as is seen in Earth's San Andreas fault.
UZH researchers have analyzed the composition and structure of faraway exoplanets using statistical tools. Their analysis indicates whether a planet is earth-like, made up of pure rock or a water-world. The larger the planet, the more hydrogen and helium surround it.
