![]() Powell to use the Discover supercomputer at the NASA Center for Climate Simulation. ![]() So Schnittman teamed up with Goddard data scientist Brian P. On a modern desktop computer, the calculations needed to make the movie frames would have taken about a decade. The visualization, created by astrophysicist Jeremy Schnittman at NASA's Goddard Space Flight Center in Greenbelt, Maryland, involved computing the path taken by light rays from the accretion disks as they made their way through the warped space-time around the black holes. Zooming into each black hole reveals multiple, increasingly distorted images of its partner. To produce them, light from the black holes must be redirected by 90 degrees, which means we’re observing the black holes from two different perspectives – face on and edge on – at the same time. ![]() Looking closely, it’s clear that these images are actually edge-on views. Both black holes produce small images of their partners that circle around them each orbit. These effects disappear when viewing the system from above, but new features emerge. ![]() The black holes appear smaller as they approach the viewer and larger when moving away. The visualization also shows a more subtle phenomenon called relativistic aberration. The rapid motion of gas near the black hole modifies the disk’s luminosity through a phenomenon called Doppler boosting – an effect of Einstein’s relativity theory that brightens the side rotating toward the viewer and dims the side spinning away. Gravitational distortion alters the paths of light coming from different parts of the disks, producing the warped image. Seen nearly edgewise, the accretion disks look noticeably brighter on one side. Visualizations like this help scientists picture the fascinating consequences of extreme gravity’s funhouse mirror. For these masses, both accretion disks would actually emit most of their light in the UV, with the blue disk reaching a slightly higher temperature. Gas orbiting lower-mass black holes experiences stronger effects that produce higher temperatures. The disks have different colors, red and blue, to make it easier to track the light sources, but the choice also reflects reality. Astronomers think that in binary systems like this, both black holes could maintain accretion disks for millions of years. The simulated binary contains two supermassive black holes, a larger one with 200 million solar masses and a smaller companion weighing half as much. These distortions play out as light from the accretion disks navigates the tangled fabric of space and time near the black holes. But as one passes in front of the other, the gravity of the foreground black hole transforms its partner into a rapidly changing sequence of arcs. Viewed from near the orbital plane, each accretion disk takes on a characteristic warped look. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas – called an accretion disk – that surrounds each one. This article will introduce an easy-to-use and powerful Video Rotator - Faasoft Video Rotator to rotate MP4 and rotate MOV 90 degrees or as your desire.A pair of orbiting black holes millions of times the Sun’s mass perform a hypnotic dance in this NASA visualization. In either case, you come to the right place. How to Rotate MOV and MP4 90 Degrees and More? The resulting video should rotate the video, but not crop the original. I would like to rotate a video that was shot in a vertical orientation.The only problem is that I took these movies with the camera turned 90 degrees. mov files that I took with my digital camera. Is there any way to rotate MOV file 180 degrees? mov video that was recorded upside down with their Camera. There is software like Free Video Flip and Rotate available that does this but produces an AVI file. I need to rotate MP4 video by 90 degrees.It is an *.MP4 video file that was taken by iPod. I need some help with rotating a video file by 90 degrees.Is there a program which does this job and works on PC? Now I need to rotate MOV file for playback. I recorded a MOV video in portrait mode with my iPhone.Have you encountered the same or similar problems that the recorded MP4 and MOV files came out upside-down when you play them on PC or Mac? The followings list some typical examples for reference. ![]() Aug 2, 2014, Posted by Shirley White The Reason That People Want to Rotate MP4 and MOV ![]()
