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.
NASA’s new 3-dimensional portrait of methane shows the world’s second-largest contributor to greenhouse warming as it travels through the atmosphere. Combining multiple data sets from emissions inventories and simulations of wetlands into a high-resolution computer model, researchers now have an additional tool for understanding this complex gas and its role in Earth’s carbon cycle, atmospheric composition, and climate system. The new data visualization builds a fuller picture of the diversity of methane sources on the ground as well as the behavior of the gas as it moves through the atmosphere.
Seen nearly edgewise, the turbulent disk of gas churning around a black hole takes on a crazy double-humped appearance. The black hole's extreme gravity alters the paths of light coming from different parts of the disk, producing the warped image. The black hole's extreme gravitational field redirects and distorts the light coming from different parts of the disk, but exactly what we see depends on our viewing angle. The greatest distortion occurs when viewing the system nearly edgewise.
11-second movie shows a computational simulation of a collision of two converging streams of interstellar gas, leading to collapse and formation of a star cluster at the center. Edge-on view shows a cross section through the two streams as they meet. Numbers rapidly increasing at upper left shows the passage of time in millions of years. Left panel shows the density of interstellar gas (yellow and red are densest) and right panel shows red and blue “tracer dyes” added to watch how the gas mixes during the collapse. Circles outlined in black are stars; stars are shown as white in the left panel, and in the right panel their color reflects the amount of the two tracer dyes in each star. The simulation reveals that gas streams are thoroughly homogenized within a very short time of...
