Coordinated observations of Jupiter in early 2017 by six ground-based telescopes and Hubble allowed UC Berkeley astronomers to study the evolution of bright plumes and connect them with cloud movements deep in the planet. They show that these plumes originate 80 kilometers below the surface cloud deck and rise up quickly into the stratosphere, where supercooled ammonia freezes to form ammonia ice clouds. The plumes create disturbances in the belts and even change their color.
A new Northwestern University study discovered that spaceflight -- both aboard a space shuttle or the International Space Station (ISS) -- has a consistent effect on the gut microbiome.
A globally important ocean algae is mysteriously scarce in one of the most productive regions of the Atlantic Ocean, according to a new paper. A massive dataset has revealed patterns in the regions where Atlantic coccolithophores live, illuminating the inner workings of the ocean carbon cycle and raising new questions.
The Hall thruster is a propulsion system that is often used by spacecraft enaged in longer missions. A recent study by Andrey Shashkov and co-workers at the Moscow Institute of Physics and Technology, Russia has shown how the operating lives of these systems can be further extended; their work was recently published in EPJ D.
An international team of Russian and Belgian researchers, including scientists from HSE University, has found out that space travel has a significant impact on the brain: they discovered that cosmonauts demonstrate changes in brain connectivity related to perception and movement.
Lithium fluoride crystals have recently been used to register the tracks of nuclear particles. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow have just demonstrated that these crystals are also ideal for detecting tracks of high-energy ions of elements even as heavy as iron.
If our eyes could see gamma rays, the Moon would appear brighter than the Sun! That's how NASA's Fermi Gamma-ray Space Telescope has seen our neighbor in space for the past decade.
A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun.
Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on exoplanets called biofluorescence, according to new Cornell University research.
By creating millions of virtual universes and comparing them to observations of actual galaxies, a University of Arizona-led research team has made discoveries that present a powerful new approach for studying galaxy formation.
