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.
This new, immersive visualization produced on a NASA supercomputer represents a scenario where a camera — a stand-in for a daring astronaut — just misses the event horizon and slingshots back out. This version is a 360-degree video that lets viewers look all around during the trip. Goddard scientists created the visualizations on the Discover supercomputer at the NASA Center for Climate Simulation. The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way galaxy. To simplify the complex calculations, the black hole is not rotating. A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds the black hole and serves as a visual reference during the fall. So do glowing...
This is a temperature map of the exoplanet WASP-43 b, made using MIRI on NASA’s James Webb Space Telescope. The planet is too close to its star to be seen individually, but its brightness was calculated by measuring the brightness of the star-planet system as a whole. WASP-43 b is tidally locked and has an average temperature of 2,280°F (1,250°C) on the dayside and 1,115°F (600°C) on the nightside. The temperature map shows that the nightside is covered in thick, high clouds, which make it appear cooler than it would if there were no clouds.
The Sun is near the maximum phase of the solar cycle, so the solar magnetic field is evolving rapidly. This predictive model is updated in near real-time with the latest measurements of the surface magnetic field. This animation shows how the Sun and the prediction are evolving with time.

Newcastle University Research Shows Climate Change Causes Methane To Be Released From The Deep Ocean
Researchers have found that frozen methane trapped under our oceans, is vulnerable to melting due to climate change and could be released into the sea.
A team of researchers at NASA's Marshall Space Flight Center in Huntsville, Alabama have created a simulation of the Apollo 12 lander engine plumes interacting with the lunar surface. The simulation animation illustrates the last 30 seconds of descent before the engine cut-off, and it shows the predicted forces that the plumes would exert on a flat computational surface. These forces are known as shear stress, which is the amount of lateral or sideways force applied over a specific area. It is the leading cause of erosion as fluids flow across a surface. The fluctuating radial patterns in the animation illustrate the intensity of predicted shear stress, with dark purple representing lower shear stress and yellow representing higher shear stress. The credits for this simulation go to...
Video interview with AHA volunteer expert: Dan Roden, M.D., FAHA, chair of the American Heart Association’s Council on Genomic and Precision Medicine and professor of medicine, pharmacology and biomedical informatics and senior vice-president for personalized medicine at Vanderbilt University Medical Center in Nashville.
This animated graph displays the frequency and signal strength of gravitational waves using a simulated dataset of galactic ultracompact binaries. The colors on the graph indicate frequencies ranging from about 0.001 to 0.01 hertz, with lighter colors representing higher frequencies. The dashed curve shows the expected sensitivity limit of the LISA (Laser Interferometer Space Antenna) mission, which is currently being designed by the ESA (European Space Agency) in collaboration with NASA for launch in the 2030s.

The findings are featured on the cover of the journal Cancer Cell • The authors of the study, from the Spanish National Research Council (CSIC) and the Spanish National Cancer Research Centre (CNIO), suggest that cognitive loss in patients with brain metastases may be due to the interference that cancer produces in neuronal circuits. • When cancer spreads in the brain, it changes the brain’s chemistry, interfering with the communication between neurons. This is a very different hypothesis from the one previously accepted, with implications for the diagnosis and treatment of brain metastases. © Atlas / CNIO
Northwestern astrophysicists developed the first numerical simulation that follows the jet evolution in a black hole-neutron star merger out to large distances. Using this model, the researchers discovered that the post-merger black hole can launch jets of material from the swallowed neutron star. Credit: Ore Gottlieb/Danat Issa/Alexander Tchekhovskoy
Jacob Taylor, a young physicist at the National Institute of Standards and Technology (NIST), has made pioneering scientific discoveries that in time could lead to significant advances in health care, communications, supercomputing, and technology. As a fellow of the Joint Quantum Institute at NIST since 2009, the 34-year-old Taylor has conceived a number of original theories, including a way to vastly improve magnetic resonance imaging to enable probing down to the cellular and molecular levels. This approach holds the promise of providing detailed information that could lead to far better diagnoses, more targeted medical treatments for patients and rapid turnaround for drug discovery.
