The black hole, embedded in a disk of dust and gas, launches a pair of particle jets traveling at nearly the speed of light. Scientists think gamma rays (magenta) detected by NASA’s Fermi Gamma-ray Space Telescope originate from the base of these jets. As the jets collide with material surrounding the galaxy, they form identical lobes seen at radio wavelengths (orange). The jets experienced two distinct bouts of activity, which created the gap between the lobes and the black hole.

A better understanding of how snow melts can help scientists recognize the signature in radar signals of heavier, wetter snow -- the kind that breaks power lines and tree limbs -- and could be a step toward improving predictions of this hazard.The model reproduces key features of melting snowflakes that have been observed in nature: first, meltwater gathers in any concave regions of the snowflake's surface. These liquid-water regions merge as they grow and eventually form a shell of liquid around an ice core, finally developing into a water drop. The visualization shows a typical snowflake less than half an inch (one centimeter) long. The snowflake is composed of individual ice crystals whose arms became entangled when they collided in the air. The extremities of the arms melt first because they are more exposed to heat from the surrounding air. Water first fills small cavities within the ice crystals, and then these overflow, allowing water to pool into droplets.\"I got interested in modeling melting snow because of the way it affects our observations with remote sensing instruments,\" Leinonen said. A radar \"profile\" of the atmosphere from top to bottom shows a very bright, prominent layer at the altitude where falling snow and hail melt, much brighter than the layers above and below. \"The reasons for this layer are still not particularly clear, and there has been a bit of debate in the community,\" Leinonen explained. Simpler models can reproduce the bright melt layer, but a more detailed model like this one can help scientists to understand it better, particularly how the type of melting snow and the radar wavelengths used to observe it relate to the brightness of the layer.A paper on the numerical model, titled \"Snowflake melting simulation using smoothed particle hydrodynamics,\" recently appeared in the Journal of Geophysical Research - Atmospheres. || ", "hits": 50 }, { "id": 12659, "url": "https://svs.gsfc.nasa.gov/12659/", "result_type": "Produced Video", "release_date": "2017-07-10T12:00:00-04:00", "title": "Colossal Cosmic Waves", "description": "When a small galaxy cluster disturbs a larger one, giant waves emanate for millions of years. || AM06_beta200_t_417_1024x576.jpg (1024x576) [52.5 KB] || AM06_beta200_t_417_1920x1080.jpg (1920x1080) [140.8 KB] || AM06_beta200_t_417.png (7344x4130) [3.5 MB] || AM06_beta200_t_417_searchweb.png (320x180) [37.8 KB] || AM06_beta200_t_417_thm.png (80x40) [3.1 KB] || ", "hits": 37 }, { "id": 12458, "url": "https://svs.gsfc.nasa.gov/12458/", "result_type": "Produced Video", "release_date": "2017-06-12T12:00:00-04:00", "title": "Shadow of the Eclipse", "description": "See the most accurate map for Aug 21, 2017's total solar eclipse. || usa_eclipse_map_16x9_1920x1080_1024x576.jpg (1024x576) [212.7 KB] || usa_eclipse_map_16x9_1920x1080_1920x1080.jpg (1920x1080) [700.1 KB] || usa_eclipse_map_16x9_1920x1080_1920x1080_thm.png (80x40) [8.0 KB] || usa_eclipse_map_16x9_1920x1080_1024x576_searchweb.png (320x180) [110.9 KB] || usa_eclipse_map_16x9_1920x1080.tif (1920x1080) [3.9 MB] || usa_eclipse_map_16x9.tif (4800x2700) [21.5 MB] || ", "hits": 65 }, { "id": 12634, "url": "https://svs.gsfc.nasa.gov/12634/", "result_type": "Produced Video", "release_date": "2017-06-12T00:00:00-04:00", "title": "Nancy Grace Roman, The Mother of Hubble - Media Resources", "description": "Interviews and b-roll of Dr. Nancy Grace Roman, \"the Mother of Hubble.\" Dr. Roman, born May 16, 1925, began working at NASA in 1959 and served as NASA's first Chief of Astronomy. || ", "hits": 77 }, { "id": 40317, "url": "https://svs.gsfc.nasa.gov/gallery/vcearth-video-wall/", "result_type": "Gallery", "release_date": "2017-02-02T00:00:00-05:00", "title": "VC Earth Video Wall", "description": "list of videos to display on video wall in Earth science exhibit at Goddard Visitor Center", "hits": 13 }, { "id": 4517, "url": "https://svs.gsfc.nasa.gov/4517/", "result_type": "Visualization", "release_date": "2016-12-13T00:00:00-05:00", "title": "Umbra Shapes", "description": "This animation shows the shape of the Moon's umbral shadow during the August 21, 2017 total solar eclipse, calculated at three different levels of detail.

It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators. We hope that your understanding and use of NASA's visualizations will only increase as your appreciation grows for the beauty of the science they portray, and the communicative power they hold. Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.You are the Project Scientist and Education and Public Outreach (EPO) lead for the Rad-X Project. What is Rad-X, why is it important, and what is the EPO and project scientist's role?NASA's Radiation Dosimetry Experiment, or RaD-X, is a low-cost, high-altitude balloon project. Its mission is to help us understand and quantify cosmic ray exposure at the top of atmosphere. That's the zone where commercial airlines fly. This is important because these cosmic rays are a primary source of ionizing radiation in the atmosphere and increase the risk of cancer and other health impacts. A pilot absorbs as much radiation as a worker in a nuclear power plant, yet the dose of radiation they receive during a cosmic storm or during the span of their career is not quantified or documented.The RaD-X payload consists of four radiation sensors that are used to measure incoming radiation. The RaD-X payload was launched on September 25, 2015 via a high-altitude research balloon. This supplements NASA's Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS) model, which helps us make informed decisions about radiation exposure safety for flight crews, the general public, and commercial space operations. RaD-X also supported Cubes in Space on their inaugural balloon flight, which carried various science projects from schools across the U.S. Cubes in Space is a global design contest in which teams of secondary school students from around the world develop unique science experiments for launch into the upper atmosphere. During the 24-hour mission, the RaD-X payload and Cubes in Space experienced altitudes above 100,000 ft. during the day and above 60,000 ft. during the night. On RaD-X, I had dual roles. First as the Project Scientist it was my job to serve as an interface between the scientists and engineers. Essentially, to help them speak the same language and communicate effectively. I was also the EPO lead. This included coordinating school visits, developing fact sheets, and interfacing with NASA Langley Research Center’s public affairs and communications.How do you use Earth visualizations? Does it have applications to the Rad-X project?Using data from the NAIRAS model, we create visualizations of predicted radiation exposure at multiple altitudes. These show exposure rates at aircraft levels and a vertical profile on global exposure rates. Now that we have successfully launched the Rad-X mission, we have started to analyze real data. During the launch we monitored (in real-time) how the measurements compared with the model predicted values from NAIRAS. Creating visualizations in real-time made the comparisons easier to interpret. || ", "hits": 20 }, { "id": 40261, "url": "https://svs.gsfc.nasa.gov/gallery/olympex/", "result_type": "Gallery", "release_date": "2015-10-15T00:00:00-04:00", "title": "OLYMPEX", "description": "The Olympic Mountain Experiment, or OLYMPEX, is a NASA-led field campaign, which will take place on the Olympic Peninsula of Washington State from November 2015 through February 2016.

These model runs are then compared to actual data to determine ways to improve the model, and therefore forecasts of the impacts of future space weather events.In mid-December of 2006, the Sun erupted with a bright flare and coronal mass ejection (CME) that launched particles Earthward. While not the brightest or largest event observed, its impact on Earth was substantial, requiring some effort to protect satellites (ESA: Reacting to a solar flare).The visualization presented here is a CCMC run of a BATS-R-US model simulating the impact of this event on Earth. Here, lines are used to represent the 'flow direction' of magnetic field of the solar wind impacting Earth, as well as the effects on Earth's geomagnetic field. A 'cut-plane' through the data illustrates the changes in the particle density in the solar wind and magnetosphere. The color of the data represents a logarithmic scaling of density, with red as the highest (1000 particles per cubic centimeter) down to blue (0.01 particles per cubic centimeter). In this simulation, each frame of the movie corresponds to two minutes of real time.In the movie, we see vertical field lines of magnetic field carried by the solar wind, coming in from the left. As this field, and the plasma carrying it, strike Earth's magnetic field, they bend and reconnect, around the Earth. Some field lines actually reconnect to the polar regions of the Earth, providing a ready flow-path for particles to reach the ionosphere and generate aurora. This interaction between the solar wind and the plasma trapped in Earth's magnetosphere also creates a density enhancement between Earth and the solar wind helping to shield Earth from some of the effects. A lower density wake forms behind Earth (the blue region). There is a circular 'hole' around the Earth which is a gap in the model. || ", "hits": 195 }, { "id": 4189, "url": "https://svs.gsfc.nasa.gov/4189/", "result_type": "Visualization", "release_date": "2014-09-25T10:00:00-04:00", "title": "Comparative Magnetospheres: A Carrington-Class CME", "description": "In an effort to understand and predict the impact of space weather events on Earth, the Community-Coordinated Modeling Center (CCMC) at NASA Goddard Space Flight Center, routinely runs computer models of the many historical events.

Tropospheric ozone is close the ground and a component of pollution. This should be distinguished from high-altitude (stratospheric) ozone which shields the Earth's surface from ultraviolet radiation. Ozone measurements from the OMI and MLS instruments on board the Aura satellite are used for deriving global distributions of tropospheric column ozone (TCO). TCO is determined using the tropospheric ozone residual method which involves subtracting measurements of MLS stratospheric column ozone (SCO) from OMI total column ozone after adjusting for intercalibration differences of the two instruments using the convective-cloud differential method. The derived TCO field, which covers one complete year of mostly continuous daily measurements from January 2005 through December 2006, is used for studying the regional and global pollution on a timescale of a few days to months. MLS and OMI are two out of a total of four instruments on board the Aura spacecraft which is flown in a sunsynchronous polar orbit at 705 km altitude with a 98.2 degree inclination. The spacecraft has an equatorial crossing time of 1:45 pm (ascending node) with around 98.8 min per orbit (14.6 orbits per day on average). OMI is a nadir-scanning instrument that at visible (350-500 nm) and UV wavelength channels (UV-1: 270-314 nm; UV-2: 306-380 nm) detects backscattered solar radiance to measure column ozone. The MLS instrument is a thermal-emission microwave limb sounder that measures vertical profiles of mesospheric, stratospheric, and upper tropospheric temperature, ozone and other constituents from limb scans ahead of the Aura satellite. The MLS profile measurements are taken about 7 min before OMI views the same location during ascending (daytime) orbital tracks. These are referred as \"collocated\" measurements between OMI and MLS. The data shows signals due to convection, biomass burning, stratospheric influence, pollution, and transport. They are capable of capturing the spatiotemporal evolution of tropospheric column ozone.
