I’ve never used Tumblr before but I’m getting back into art and thought this was the place. Anyways have some stuff. HD 189733 b! Planet human.

Feeling Nostalgic With Old 2017 NASA Image: NASA Hubble Finds a True Blue Planet

This image was taken in 2017. It remains mesmerizing to this day.

NASA Hubble Finds a True Blue Planet

This illustration shows HD 189733b, a huge gas giant that orbits very close to its host star HD 189733. The planet’s atmosphere is scorching with a temperature of over 1000 degrees Celsius, and it rains glass, sideways, in howling 7000 kilometre-per-hour winds. At a distance of 63 light-years…

Scientists chart Mach 7 winds on a Jupiter-sized exoplanet

Scientists chart Mach 7 winds on a Jupiter-sized exoplanet

When scientists discovered a Jupiter-sized exoplanet in the Vulpecula constellation, they knew the weather there wasn't great. That's because HD 189733b orbits its star every 2.2 days at a speed of 341,000 mph and has an average surface temperature…

Can we all just take a moment to appreciate that there is a planet where it rains marbles?

Well, sort of anyway. Molten glass is pretty much the same thing, right?

(Space.com)   There's a "blue marble" alien planet just 63 light-years from Earth, but the world is anything but friendly to life. Researchers say the blue color in the atmosphere likely comes from a rain of molten glass. This super-hot glass rain is just one consequence of the close proximity between the gas giant alien planet HD189733b and its sun. which causes daytime temperatures to soar as high as 1,700 degrees Fahrenheit (930 degrees Celsius), scientists said.

Excerpt #299

Uwaru took the last step to the top of the hill and looked out over the horizon. The sky was a beautiful blend of azure and swiftly moving clouds. There was a moderate of rain, the mix of glass shards and beads flew sideways in the wind. Uwaru increased the glow of her radiance to ensure the rain didn't grind against her skin. She opened the first lid of her fifth eye to expand her view of the horizon and of the fantastic explosions of energy in the sky. It was even a little cool this day, the heat from the sun dipping down to just below a thousand degrees Celsius. The family unit was back in the caves, tending to the crystal crops and the fire worms. They would soon be able to harvest both for consumption before the winter slumber. Uwaru shivered as it began to cool once more. There was a distant explosion in the sky as a cloud violently tore itself apart. Her bristles shook at the happy memory of her first time seeing the clouds with her mother. She touched her chest to honor her deceased parent and then headed back down the hill towards the cave entrance. There was still much preparation before the slumber and the hunting party would be back either with or without the mighty haul of a skyrider. That bounty would feed the entire family unit and allow them to save the crystals and fireworms which would yield greater harvests next year. She increased her pace, her six legs moving almost like a wave as she bounded toward the caves. The hue of her radiance changed to a bright white, easily betraying her excitement as she neared the entrance. The pegs were still missing from the holes so the hunters had not yet returned. Uwaru pouted and resigned herself to wait, entering and heading toward the crystal cave.

Photo: The planet, seen in an artist's conception, doesn't have any oceans. Instead, the blue colour is caused by dust, made of glass, swirling violently in the planet's atmosphere, where winds are whipping by at about 7,000 kilometres per hour. (European Space Agency) Planet orbiting nearby star is Earthly blue The colour of a planet outside our solar system has been observed for the first time – and it is blue like Earth. The blueness of HD189733b, a gas giant that orbits a star just 63 light years away, was detected by the Hubble Telescope, an international group of scientists reported Wednesday in a news release from the ESA/Hubble Information Centre and in a scientific paper posted online. The peer-reviewed article has been accepted for publication in the Aug. 1 issue of Astrophysical Journal Letters. The colour is described in the release as "deep azure blue, reminiscent of Earth’s colour as seen from space." It does not indicate that the planet has oceans. Instead, the researchers report that it is due to a dust — made of specks of glass — in the planet's violently stormy atmosphere that scatter blue light. "This planet has been studied well in the past, both by ourselves and other teams," said Frederic Pont, a University of Exeter researcher who leads the Hubble observing program, in a statement. "But measuring its colour is a real first — we can actually imagine what this planet would look like if we were able to look at it directly." The colour was not imaged directly by the telescope, but detected with an instrument called the Space Telescope Imaging Spectrograph, which measures the levels of different colours of light in the Hubble's field of view, including the light reflecting off the planet. As the planet passed behind its star over the course of each orbit, the spectrograph showed that the level of blue light decreased. "From this, we can gather that the planet is blue, because the signal remained constant at the other colours we measured," said Tom Evans, a University of Oxford researcher who co-authored the paper, in a statement. Aside from not having oceans, the blue planet has many other features that make it uninhabitable. It belongs to a special class of gas giants called "hot Jupiters." As such, it has a temperature of over 1000 C on the side that faces closest to its star and 7000-kilometre-per-hour winds in its atmosphere that may cause it to "rain" glass sideways. The planet is located so close to its star that the star's gravity keeps the same side of the planet constantly facing it (as the Earth's gravity does to the Moon), while the other side is in perpetual darkness. - Source: CBCnews
