An international team of researchers, led by Professor Shoji Torii of Waseda University, succeeded in the direct, high-precision measurements of cosmic-ray electron spectrum up to 4.8 TeV, based on observations with the Calorimetric Electron Telescope (CALET). Observations by CALET are expected to reveal the mysteries of cosmic-rays and nature of dark matter in the future.
A Southwest Research Institute-led team discovered never-before-detected, fine-grained structures in the Sun's outer atmosphere, or corona. The team imaged this critical region in detail using sophisticated software techniques and longer exposures from the COR-2 camera on board NASA's Solar and Terrestrial Relations Observatory-A (STEREO-A).
An MIT study finds black holes and neutron stars are key to measuring our expanding universe.
Using the power and synergy of two space telescopes, astronomers have made the most precise measurement to date of the universe's expansion rate.
Observations made by researchers using a National Science Foundation (NSF) detector at the South Pole and verified by ground- and space-based telescopes have produced the first evidence of one source of high-energy cosmic neutrinos.
An international team of astronomers has discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed the 'Sausage' galaxy. The cosmic crash was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy, fashioning both its inner bulge and its outer halo, the astronomers report in a series of new papers.
Scientists have found that molecular oxygen around comet 67P is not produced on its surface, as some suggested, but may be from its body.
New evidence for a rapid crystallization and crust formation on Mars has just been published in a study from the Centre for Star and Planet Formation at the Natural History Museum of Denmark, University of Copenhagen. The study, based on the analysis of the rare Mars meteorite Black Beauty, significantly expands the window for when life might have existed on Mars.
The galaxy is rich in grease-like molecules, according to an Australian-Turkish team. Astronomers at the University of New South Wales in Sydney (UNSW), and Ege University in Turkey used a laboratory to manufacture material with the same properties as interstellar dust and used their results to estimate the amount of 'space grease' found in the Milky Way. Their results appear in a paper in Monthly Notices of the Royal Astronomical Society.
Using mass spectrometry data from NASA's Cassini spacecraft, scientists found that large, carbon-rich organic molecules are ejected from cracks in the icy surface of Saturn's moon Enceladus. Southwest Research Institute scientists think chemical reactions between the moon's rocky core and warm water from its subsurface ocean are linked to these complex molecules.
