A review paper published in EPJ H examines the 6-decade history of neutral particle analysis (NPA), developed in Ioffe Institute, Saint Petersburg, Russia a vital diagnostic tool used in magnetic plasma confinement devices such as tokamaks that will house the nuclear fusion process and generate the clean energy of the future.
New mathematical framework predicts that star systems Kepler-34, -35, -38, -64 and -413 with circumbinary giant planets have stable Habitable Zones, potentially suitable for life
In a novel laboratory investigation of the initial atmospheres of Earth-like rocky planets, researchers at UC Santa Cruz heated pristine meteorite samples in a high-temperature furnace and analyzed the gases released. Their results suggest that the initial atmospheres of terrestrial planets may differ significantly from many of the common assumptions used in theoretical models of planetary atmospheres.
In April 2019, scientists released the first image of a black hole in galaxy M87 using the Event Horizon Telescope (EHT). However, that remarkable achievement was just the beginning of the science story to be told.
An MIT study narrows the search for particles called ultralight bosons, which, if they exist, could be an important component of dark matter. Certain ultralight bosons would be expected to put the brakes on the spin of black holes, but the new results show no such slowdown.
An international team led by West Virginia University researchers studied RCW 120 to analyze the effects of stellar feedback, and found that RCW 120 must be less than 150,000 years old, which is very young for such a nebula.
In the search for life on other planets, the presence of oxygen in a planet's atmosphere is one potential sign of biological activity that might be detected by future telescopes. A new study, however, describes several scenarios in which a lifeless rocky planet around a sun-like star could evolve to have oxygen in its atmosphere.
The new study focuses on the outgoing flux of phase-volume, rather than the phase-volume itself. Since the flux is finite even when the volume is infinite, this flux-based approach avoids the artificial problem of infinite probabilities, without ever introducing the artificial strong interaction region.
Scientists from the Skoltech Space Center (SSC) have developed nanosatellite interaction algorithms for scientific measurements using a tetrahedral orbital formation of CubeSats that exchange data and apply interpolation algorithms to create local maps of physical measurements in real time. The study presents an example of geomagnetic field measurement, which shows that these data can be used by other satellites for attitude control and, therefore, provided on a data-as-a-service basis.
A new study conducted jointly by the ULiège Climatology Laboratory and the University of Reading (England) suggests that 34% of the Antarctic ice shelves could disappear by the end of the century if the planet warms up by 4°C compared with pre-industrial temperatures. This melting could lead to a significant rise in sea levels. This study is published in the journal Geophysical Research Letters.
