A groundbreaking study, harnessing observations from the European Space Agency's Gaia space telescope, has revealed evidence of discrepancies between observed stellar motions and predictions from Newton's universal law of gravitation and Einstein's general relativity. The research, spearheaded by Professor Kyu-Hyun Chae of Sejong University, Seoul, scrutinized the orbital dynamics of appro

Structured light waves with spiral phase fronts carry orbital angular momentum (OAM), attributed to the rotational motion of photons. Recently, scientists have been using light waves with OAM, and these special "helical" light beams have become very important in various advanced technologies like communication, imaging, and quantum information processing. In these technologies, it's crucial to k

That the planet Mars had habitable surface environments early in its existence has been firmly established by the scientific community. These environments provided water, energy sources, elements like carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, as well as critical catalytic transition metals associated with life as we know it. However, whether that potential stimulated further pr

Earth planning date: Wednesday August 8, 2023: Curiosity continues her steady winter drive through the Kalavryta quadrangle with her sights set on the Gediz Vallis ridge ahead! Behind her, Curiosity leaves evidence of her route as wheel tracks in the sand and dust - a robotic version of footprints on the Martian surface. Interestingly, the gaps in the rover wheels were designed with a pattern th

Perseverance spent this week on Mars roving across the top of the Jezero fan- from Mount Meeker to Dream Lake- in search of yet another sample for return to Earth. This upper region known as Lobe K is expected to contain some of the most recently deposited materials within the delta sequence, providing the opportunity to place both upper and lower bounds on the timing of aqueous activity that bu

NASA's Mars Phoenix Lander gathered images of itself for this selfie from June 5 through July 12, 2008, with its Surface Stereo Imager (SSI). This mosaic is made up of more than 100 different SSI pointings, with images taken through three different filters at each pointing. 15 years ago in August 2008, Phoenix completed its three-month mission studying Martian ice, soil, and atmosphere. Th

Dr. John Bennewitz, an assistant professor in the Department of Mechanical and Aerospace Engineering at The University of Alabama in Huntsville (UAH), has been awarded a $650,000, 45-month Air Force Office of Scientific Research (AFOSR) grant to develop an advanced propulsion system that will facilitate surveillance of space between the Earth and the Moon by the United States Space Force. The re

China on Thursday launched the CERES-1 Y7 carrier rocket from the Jiuquan Satellite Launch Center in northwest China, sending seven satellites into a planned orbit. The commercial rocket blasted off at 12:03 p.m. (Beijing Time) from the launch site, carrying seven satellites, including the Xiguang-1 01 satellite. Xiguang-1 01, equipped with hyperspectral, infrared, and panchromatic c
