Published James Webb spots super old, massive galaxies that shouldn't exist
(via sciencedaily.com) A team of international researchers have identified six candidate galaxies that existed roughly 500 to 700 million years after the Big Bang and are about as big as the modern Milky Way Galaxy -- a feat that scientists didn't think was possible.
Published Better tools needed to determine ancient life on Mars
(via sciencedaily.com) Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new research.
Published Researchers discover mysterious source of 'heartbeat-like' radio bursts in a solar fare
(via sciencedaily.com) A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun's atmosphere, according to a new study. An international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun's surface.
Published Improving the performance of satellites in low Earth orbit
(via sciencedaily.com) On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.
Published Physicists create new model of ringing black holes
(via sciencedaily.com) Original source A new analysis has modeled black hole collisions in more detail and revealed so-called nonlinear effects within gravitational waves. Nonlinear effects happen 'when waves on the beach crest and crash.'
Published Newly discovered form of salty ice could exist on surface of extraterrestrial moons
(via sciencedaily.com) Original source An international team has found two new crystal structures for salty ice, or solid hydrate made from water and sodium chloride. The newly discovered material's properties match those of the substance seen on the surface of icy moons, like Europa and Ganymede, and may offer clues to their icy oceans.
Published Space travel influences the way the brain works
(via sciencedaily.com) Original source Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting -- even after 8 months back on Earth.
Published Astrophysics: Scientists observe high-speed star formation
(via sciencedaily.com) Original source New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.
Published Tadpole playing around black hole
(via sciencedaily.com) Original source A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.
Published Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?
(via sciencedaily.com) Original source If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as well. The new James Webb Space Telescope (JWST) has contributed to the discovery of different ices in a molecular cloud, 'Chameleon 1' -- one of the coldest and darkest regions to have ever been explored. Astronomers assume that these types of molecules were also present in the cold cloud of gas and dust forming our own solar system.
