Supermassive Black Hole Scale Comparison
Supermassive Black Hole Scale Comparison All monster black holes are not equal. Watch this video to see how they compare to each other and to our solar system.

ALT An image taken by NASA's Ingenuity Mars Helicopter using its high-resolution color camera mounted in the helicopter's fuselage and pointed approximately 22 degrees below the horizon. This is a color image showing the reddish brown rocky terrain of Mars with a few small hills in the foreground and background. A small shadow of Ingenuity appears in the lower right-hand corner of the frame. The Perseverance Mars rover appears in the upper left-hand corner of the frame. It is small but the shape and outline of the rover is very clear. There is a hazy blue sky in the background. This image was acquired on April 23, 2023, the date of Ingenuity's 51st flight.

ALT The planet Uranus on a black background. The planet appears light blue with a large, white patch on the right side. On the edge of that patch at the upper left is a bright white spot. Another white spot is located on the left side of the planet at the 9 o’clock position. Around the planet is a system of nested rings. The outermost ring is the brightest while the innermost ring is the faintest. Unlike Saturn’s horizontal rings, the rings of Uranus are vertical and so they appear to surround the planet.

ALT Modified version of a previous, popular artist illustration of the TRAPPIST-1 star system. The background is black. At the top there is a “TRAPPIST-1 System” label in bold white text. At far left is a representation of the TRAPPIST-1 star, an M class dwarf star. It is seen as a glowing orange-yellow semi-circle. To the right of the star, illustrations of its planets are shown in a line. There are seven, with slight variations in sizes. They are labeled b, c, d, e, f, g and h, with b being closest to the star. They all resemble mottled clay marbles in browns and dark greens. The planet TRAPPIST-1 b has been spotlighted to stand out. The other planets are dimmed down to be less visible. The planet b also has a white label as opposed to gray letter labels for the rest of the planets. At bottom right is the word “Illustration (2018)” in tiny gray text.

ALT Graphic titled “Rocky Exoplanet LHS 475 b Transit Light Curve, NIRSpec Bright Object Time-Series Spectroscopy.” Behind the graph is an illustration of the planet and its star. The graph, or spectrum, shows the change in relative brightness of the star-planet system between 3:00 p.m. and 6:00 p.m. in Baltimore, Maryland, on August 31, 2022. The spectrum shows that the brightness of the system remains steady until the planet begins to transit the star. It then decreases, representing when the planet is directly in front of the star. The brightness increases again when the planet is no longer blocking the star, at which point it levels out. The graph shows data in purple circles, which chart measurements before, during, and after the transit. Data form a U-shaped valley of low brightness labeled “Starlight blocked by the planet” at 5 p.m. This dip cuts into a flat plain of high brightness labeled “Starlight,” which starts before the U-shaped dip, and resumes after the dip.

ALT The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range.
