NASA's Chandra X-ray Observatory has released new three-dimensional (3D) models of celestial objects, allowing people to view and print representations of stars in various life stages. These models are based on advanced theoretical frameworks and data from space telescopes like Chandra, offering clear insights into cosmic evolution. The four new 3D-printable models include Cassiopeia A, Cygnus Loop, and the star BP Tau. These tangible models enable individuals to examine replicas of these stars from all angles. For example, Cassiopeia A combines X-ray data from Chandra and infrared data from the James Webb Space Telescope to reveal details about the "Green Monster" structure, enhancing understanding of the supernova explosion that created it 340 years ago. The Cygnus Loop represents...
This text shows the distribution of material from a slice taken from one of the turbulence simulations. The colors represent density, with dark blue indicating the least dense regions and red representing the thickest areas. The black dots mark the positions of the tracer particles, which move along with the material and record the conditions they encounter. This process creates a history of how pockets of density change over time. Courtesy of NASA/E. Scannapieco et al. (2024), ASU.
ESA’s EarthCARE satellite deploys its 11-meter solar wing and opens its cloud profiling radar antenna. The collected data will improve our understanding of the impact of clouds and aerosols on Earth’s radiation balance for climate modeling and weather forecasting. This information will help clarify their influence on Earth’s energy balance and their potential impact on future climate.
