Monecky - Grandes Sonhos

This is the of a . It’s so similar to our . Just released by the and European Research Council. The image of a gigantic black hole at the centre of the M87 — 53m light years away and 6bn times bigger than the — was compiled using data pulled from a network of eight radio telescopes, from the South Pole to Hawaii. As it is impossible to see inside a black hole because no light or electromagnetic radiation can escape its overwhelming , the international team has imaged the black hole’s outer edge, or “event horizon”. It shows a bright ring of — a ring of fire created by light particles that would normally travel in a straight line — bent into a circular path by extreme gravity before they fall into the hole. Inside the ring we see the shadow of the hole itself. Our own also has a huge black hole at its heart. The history of science will be divided by the time before the image and the time after the image. Source:ft.com

Jupiter is perpetually covered with clouds composed of ammonia crystals and possibly ammonium hydrosulfide. The clouds are located in the tropopause and are arranged into bands of different latitudes, known as tropical regions. These are sub-divided into lighter-hued zones and darker belts. The interactions of these conflicting circulation patterns cause storms and turbulence. Wind speeds of 100 m/s (360 km/h) are common in zonal jets. The zones have been observed to vary in width, color and intensity from year to year, but they have remained sufficiently stable for scientists to give them identifying designations.

The cloud layer is only about 50 km (31 mi) deep, and consists of at least two decks of clouds: a thick lower deck and a thin clearer region. There may also be a thin layer of water clouds underlying the ammonia layer. Supporting the idea of water clouds are the flashes of lightning detected in the atmosphere of Jupiter. These electrical discharges can be up to a thousand times as powerful as lightning on Earth. The water clouds are assumed to generate thunderstorms in the same way as terrestrial thunderstorms, driven by the heat rising from the interior.

You’ve just crossed over into the Twilight Zone. This image captures the swirling cloud formations in Jupiter’s terminator – the region where day meets night.

This image is one in a series of images taken in an experiment to capture the best results for illuminated parts of Jupiter’s polar region. For JunoCam to collect enough light to reveal features in Jupiter’s dark twilight zone, the much brighter illuminated day-side of the planet becomes overexposed with the higher exposure.
