   COSMOCHEMISTRY- AN OUTLOOK Cosmochemistry is the study of the chemical composition of the universe and the processes that produced those compositions. This is a tall order, to be sure. Understandably, cosmochemistry focuses primarily on the objects in our own solar system, because that is where we have direct access to the most chemical information. That part of cosmochemistry encompasses the compositions of the Sun, its retinue of planets and their satellites, the almost innumerable asteroids and comets, and the smaller samples (meteorites, interplanetary dust particles or “IDPs,” returned lunar samples) derived from them. From their chemistry, determined by laboratory measurements of samples or by various remote-sensing techniques, cosmochemists try to unravel the processes that formed or affected them and to fix the chronology of these events. Cosmochemistry or chemical cosmology is the study of the chemical composition of matter in the universe and the processes that led to thos

                   How the Greenland ice sheet can nevertheless be stored Greenland is the world's second largest landmass covered by ice; only Antarctica is bigger. The Greenland ice sheet is greatly affected by the effects of climate change. If the ice melts completely it could cause a sea level rise of more than seven meters - a disaster for coastal areas around the world and for those who live there. Time series of ice volume and spatial extents of the GrIS for warming scenarios without mitigation. a, Sketch of applied warming and cooling scenarios in this study. The warming period lasts for 100 years, followed by varying cooling phases. The black line corresponds to scenarios without mitigation as shown in this figure. b, Evolution of total GrIS ice volume simulated by PISM-dEBM, without reversal of the temperature anomalies (black line in panel a), for different temperature anomalies between ΔTJJA = 0 °C and 7.0 °C above present. The warming period lasts for 100 years until y

                    New styles in sun's layers should assist scientists remedy sun mystery Astronomers are one step in the direction of expertise in one of the maximum enduring solar mysteries, having captured extraordinary facts from the sun's magnetic subject. Small-scale magnetic structures of the ‘quiet sun’ at high resolution His groundbreaking data accrued from the US National Science Foundation's (NSF) Daniel K Inouye Solar Telescope (DKIST) in Hawaii—the most effective sun telescope in the international—has provided the most exact representations thus far of the magnetic discipline of the so-referred to as 'quiet' floor of the sun.   An international team of scientists, which include researchers from the University of Sheffield, believe the facts have implications for the way we model power transfer among the layers of the solar system. The research has been posted in Astrophysical Journal Letters. This may assist give an explanation for one of the biggest c

  Chandrayaan-3’s measurements of sulfur open the doorways for lunar technology and exploration In a thrilling milestone for lunar scientists around the world, India’s Chandrayaan-3 lander touched down 375 miles (six hundred km) from the south pole of the Moon on Aug. 23, 2023. In just beneath 14 Earth days, Chandrayaan-3 provided scientists with precious new information and in addition idea to discover the Moon. And the Indian Space Research Organization has shared those initial consequences with the sector. While the statistics from Chandrayaan-3’s rover, named Pragyan, or “wisdom” in Sanskrit, showed the lunar soil includes expected elements along with iron, titanium, aluminum and calcium, it also showed an surprising surprise – sulfur. Planetary scientists have acknowledged that sulfur exists in lunar rocks and soils, but simplest at a completely low concentration. These new measurements imply there may be a better sulfur attention than anticipated. Pragyan has devices tha

                * The Moon: A Second Home in the Solar System* The Moon will be the first place where humans learn to live on another celestial body. Just three days from Earth, the Moon has low gravity and natural resources that make it an ideal location to prepare people and machines for venturing farther into space. As a repository of four billion years of solar system history and as a place to observe the Earth and the universe, it has great scientific potential. Exploration of the Moon will also reveal whether the resources available in space will allow humans to live off the land. In the 1960s, robotic spacecraft from the United States and the Soviet Union began exploring the Moon. The first soft landing was made in 1966 by the Soviet spacecraft Luna-9. It was followed by several more Soviet and U.S. lunar missions, including orbiters, sample-return missions, and rovers. During this period, six Apollo crews also landed on the Moon and returned samples to Earth. Thanks to these dr
