Flying through Dulles Airport near D.C.? If you’re taking the Metro, expect to be awed by almost 40 recently installed images from #NASAWebb, paired with more than 30 from the ever-active Hubble, on your way to the main terminal: https://bit.ly/4qPfl7m #wmata 🔭 🧪

this is actually one of the hubble images of all time
An image is split in two. In the bottom left of the first image a bright blue ring appears, slightly fading in all directions, with a small blue dot in the middle. Red and orange waves of gas ripple, arcing from top left to top right. A light blue center appears out of the sea of red, and several bright white dots shine through. In the top right, dark blue gas emanates from the blackness of space. An image is split in two.

NEW: Is frozen water around other stars? #NASAWebb provided proof for the first time: It is! Webb identified water ice around HD 181327, a Sun-like star that lies 155 light-years away. The majority is found where it’s coldest—farthest from the star: webbtelescope.pub/42Vopw0 🔭 🧪
An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.

NEW: Saturn’s moon Titan has weather similar to Earth’s, but driven by methane evaporation and condensation. Astronomers have found evidence for clouds bubbling up over Titan’s northern hemisphere for the first time, using #NASAWebb and Keck observatory: webbtelescope.pub/3GofvQ1 🔭 🧪
Two rows of three images. Top row is labeled Webb 11 July 2023 and the bottom row Keck 14 July 2023). The first column, labeled atmosphere and surface, shows two full-color images of Titan, appearing in mottled shades of yellow and brown with a blue haze around the edges. A bright spot near the top of Titan in each has an arrow pointing to it. The second column, labeled troposphere, shows two images in shades of orange. Each image is relatively featureless except for a bright spot near the top with an arrow. The third column, labeled stratosphere, also shows two images in shades of orange. The top image, taken July 11, is featureless and has no arrow. The bottom image, taken July 14, has a bright spot near the top with an arrow.

#NASAWebb provides detailed views of Herbig-Haro 49/50—an outflow from the jet of a nearby still-forming star. This science visualization flies along the outflow and demonstrates how it actually has no relationship to the more distant spiral galaxy: webbtelescope.pub/4iGQg9K 🔭 🧪

NEWS: #NASAWebb captured Lynds 483 in unprecedented detail. Two forming stars hidden in one pixel at the center are responsible for sending out these vibrant jets and outflows. Examine the twists and arcs in these ejections up close: webbtelescope.pub/4h538oK 🔭 🧪
At the center is a thin vertical cloud known as Lynds 483 that is shaped like an hourglass with two lobes and irregular edges. At lower center, in the middle of the hourglass, are two discrete bright white, tiny blobs of light that have raced away from the hidden central stars. The top lobe shows a more prominent orange U-shape. Orange bleeds into light purple, and brighter pink at its edges. Some background stars are visible through sections of this lobe. Higher up, there is an orange arc. Some brighter pink material extends to the top edges near the center. In the lower lobe, less orange is visible. More opaque light purple is in its top third, rippling out into semi-transparent blues and pinks. The lower lobe has more texture. V-shaped areas to the left and right of the lobes are darkest, and the background stars in these areas appear orange. Elsewhere, the black background of space is clearer, speckled with tiny white stars and faint orange galaxies.

Similar to how #NASAWebb’s spectrographs “dissect” infrared light, let us break down the benefits of spectroscopy, a technique that helps scientists understand the chemical makeup of a star’s surrounding environment or planet’s atmosphere. 🔭 🧪

If they wanted to take over the country, they only had to wait like three weeks until every technocratic nerd was unreachably distracted.

They fundamentally do not understand us, and that is why they will lose.
Civ 7 comes out on February 11th 2025.
