Nicole SharpSeeking Uranus’s SpinUranus is one of our solar system’s oddest planets. An ice giant, it spins on its side. We originally estimated its rate of rotation using measurements from Voyager 2, the only spacecraft to have visited the planet. But that measurement was so imprecise that within two years, astronomers could no longer use it to predict where the planet’s poles were. Now a <a href="https://www.nature.com/articles/s41550-025-02492-z" rel="nofollow noopener noreferrer" target="_blank">new study</a>, drawing on over a decade of Hubble observations of Uranus’s auroras, has pinned down the planet’s rotation rate far more precisely: 17 hours, 14 minutes, and 52 seconds. While that’s within the original measurement’s 36-second margin of error, the new measurement has a margin of error of only 0.036 seconds. In addition to helping plan a theoretical future Uranus mission, this more accurate rotation rate allows researchers to reexamine decades of data, now with certainty about the planet’s orientation at the time of the observation.

Light rays from accretion disks around a pair of orbiting supermassive black holes make their way through the warped space-time produced by extreme gravity in this detailed computer visualization. The simulated accretion disks have been given different false color schemes, red for the disk surrounding a 200-million-solar-mass black hole, and blue for the disk surrounding a 100-million-solar-mass black hole. For these masses, though, both accretion disks would actually emit most of their light in the ultraviolet. The video allows us to see both sides of each black hole at the same time. Red and blue light originating from both black holes can be seen in the innermost ring of light, called the photon sphere, near their event horizons. In the past decade, gravitational waves from black hole collisions have actually been detected, although the coalescence of supermassive black holes remains undiscovered.

grobiThe black hole’s extreme gravitational field redirects and distorts 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.As our viewpoint rotates around the black hole, we see different parts of the fast-moving gas in the accretion disk moving directly toward us. Due to a phenomenon called "relativistic Doppler beaming," gas in the disk that's moving toward us makes that side of the disk appear brighter, the opposite side darker. This effect disappears when we're directly above or below the disk because, from that angle, none of the gas is moving directly toward us.When our viewpoint passes beneath the disk, it looks like the gas is moving in the opposite direction. This is no different that viewing a clock from behind, which would make it look like the hands are moving counter-clockwise.CORRECTION: In earlier versions of the 360-degree movies on this page, these important effects were not apparent. This was due to a minor mistake in orienting the camera relative to the disk. The fact that it was not initially discovered by the NASA scientist who made the movie reflects just how bizarre and counter-intuitive black holes can be!Credit: NASA’s Goddard Space Flight Center Jeremy Schnittman (NASA/GSFC) Scott Wiessinger (USRA) Francis Reddy (University of Maryland College Park) Francis Reddy (University of Maryland College Park)>><a href="https://svs.gsfc.nasa.gov/13326#section_credits" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://svs.gsfc.nasa.gov/13326#section_credits</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/blackhole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#blackhole</a> <a href="https://defcon.social/tags/astrophysics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophysics</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ESA</a>

grobiBlack Hole Accretion Disk VisualizationCredit: NASA’s Goddard Space Flight Center Jeremy Schnittman (NASA/GSFC) Scott Wiessinger (USRA) Francis Reddy (University of Maryland College Park) Francis Reddy (University of Maryland College Park)This new visualization of a black hole illustrates how its gravity distorts our view, warping its surroundings as if seen in a carnival mirror. The visualization simulates the appearance of a black hole where infalling matter has collected into a thin, hot structure called an accretion disk. The black hole’s extreme gravity skews light emitted by different regions of the disk, producing the misshapen appearance.Bright knots constantly form and dissipate in the disk as magnetic fields wind and twist through the churning gas. Nearest the black hole, the gas orbits at close to the speed of light, while the outer portions spin a bit more slowly. This difference stretches and shears the bright knots, producing light and dark lanes in the disk.Viewed from the side, the disk looks brighter on the left than it does on the right. Glowing gas on the left side of the disk moves toward us so fast that the effects of Einstein’s relativity give it a boost in brightness; the opposite happens on the right side, where gas moving away us becomes slightly dimmer. This asymmetry disappears when we see the disk exactly face on because, from that perspective, none of the material is moving along our line of sight.Closest to the black hole, the gravitational light-bending becomes so excessive that we can see the underside of the disk as a bright ring of light seemingly outlining the black hole. This so-called “photon ring” is composed of multiple rings, which grow progressively fainter and thinner, from light that has circled the black hole two, three, or even more times before escaping to reach our eyes. ...>> <a href="https://svs.gsfc.nasa.gov/13326" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://svs.gsfc.nasa.gov/13326</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/blackhole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#blackhole</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/astrophysics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophysics</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a>

Rose et al.also in this case (after A2029 and Coma) the reported amount of turbulent velocity is low (~150 km/s) which translates into a 2.5% of the thermal cluster energy - too low to offset the cooling flow of gas. As for the previous results, this is very puzzling.<a href="https://mastodon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://mastodon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://mastodon.social/tags/astrodon" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrodon</a>

Light rays from accretion disks around a pair of orbiting supermassive black holes make their way through the warped space-time produced by extreme gravity in this detailed computer visualization. The simulated accretion disks have been given different false color schemes, red for the disk surrounding a 200-million-solar-mass black hole, and blue for the disk surrounding a 100-million-solar-mass black hole. For these masses, though, both accretion disks would actually emit most of their light in the ultraviolet. The video allows us to see both sides of each black hole at the same time. Red and blue light originating from both black holes can be seen in the innermost ring of light, called the photon sphere, near their event horizons. In the past decade, gravitational waves from black hole collisions have actually been detected, although the coalescence of supermassive black holes remains undiscovered. <a href="https://www.nasa.gov/universe/new-nasa-visualization-probes-the-light-bending-dance-of-binary-black-holes/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.nasa.gov/universe/new-nasa-visualization-probes-the-light-bending-dance-of-binary-black-holes/</a> <a href="https://apod.nasa.gov/apod/ap200825.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap200825.html</a> <a href="https://en.wikipedia.org/wiki/Accretion_disk" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Accretion_disk</a> <a href="https://apod.nasa.gov/apod/ap190411.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap190411.html</a> <a href="https://svs.gsfc.nasa.gov/14132/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://svs.gsfc.nasa.gov/14132/</a> <a href="https://ui.adsabs.harvard.edu/abs/1993AmJPh..61..619N/abstract" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://ui.adsabs.harvard.edu/abs/1993AmJPh..61..619N/abstract</a> <a href="https://apod.nasa.gov/htmltest/rjn_bht.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/htmltest/rjn_bht.html</a> <a href="https://en.wikipedia.org/wiki/Photon_sphere" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://en.wikipedia.org/wiki/Photon_sphere</a> <a href="https://apod.nasa.gov/apod/ap201104.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap201104.html</a><a href="https://apod.nasa.gov/apod/ap250506.html" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://apod.nasa.gov/apod/ap250506.html</a><a href="https://defcon.social/tags/space" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#space</a> <a href="https://defcon.social/tags/blackhole" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#blackhole</a> <a href="https://defcon.social/tags/astrophotography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astrophotography</a> <a href="https://defcon.social/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://defcon.social/tags/astronomy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#astronomy</a> <a href="https://defcon.social/tags/science" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#science</a> <a href="https://defcon.social/tags/nature" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nature</a> <a href="https://defcon.social/tags/NASA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NASA</a> <a href="https://defcon.social/tags/ESA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ESA</a>
