Asteroid Ryugu once had liquid water flowing through it

Samples retrieved from asteroid Ryugu indicate that it once had flowing water in far greater volumes than previously thought possible, suggesting that similar objects may have played a role in deliver...

eclipse from earth | eclipse from the moon

The lunar eclipse as seen above the Space Environments Complex at NASA’s Glenn Research Center at Neil Armstrong Test Facility in Sandusky, Ohio, during the early hours of March 14, 2025.

The solar eclipse as seen from the surface of the Moon in Mare Crisium by the Blue Ghost Mission 1 lander. The Sun's corona shines as a bright circle around the dark disc of the Earth. A "diamond ring" flare glows at the five o'clock position against the darkness of space. Credit: Firefly Aerospace

I spent a lot of time in my book breaking down WHY this is happening — it’s *content meets community*

- A lot of people don’t want “politics” or “news”, they want to be entertained…comedy, culture

- They want to feel like they’re listening to someone relatable, who talks like them, is like them.

one thing i keep thinking about is how there is simply no way to design a constitutional system that can resist authoritarian incursion if participants in that system do not actually care that much

Last night's eclipse from the perspective of the moon. dang.

Nadia Drake @nadiadrake.bsky.social · Mar 14

Wow — this shot of a total solar eclipse is truly one of the coolest things I've seen in a long time. Shot from the moon's surface by @firefly-aerospace.bsky.social's Blue Ghost lander, it shows the sun about to emerge from behind the Earth. What a beautiful cosmic perspective! 💍

An image of a total solar eclipse, seen from the moon's surface. The sun's light is a thin ring around a dark Earth, except where the sun is beginning to emerge from behind the Earth, producing what's colloquially called the "diamond ring" effect.

Just past sunrise on Sol 4476, the Mars Curiosity Rover used MastCam to take a large mosaic of the surroundings. Here’s my favorite part, looking towards the future drive path and boxworks.

Rocks and sand. A shadow of a butte darkens the left. More buttes are in the distance; we’ll see more of them later.

tired of people treating trump like he is anything other than an ego-driven simpleton (i wrote this, this is a piece about why he is nothing more than an ego driven simpleton.)

It is hard to describe the president’s first month and a half in office as something other than a retribution campaign against the American people.

these webb/hubble images are truly incredible. the fact that we can see the universe in different wavelengths of light and spot so many unseen details is mind-blowing 🌌

Two observations of a portion of the galaxy NGC 628 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is roughly centered and the galaxy’s arms appear to rotate counterclockwise. The spiraling filamentary structure looks somewhat like a cross section of a nautilus shell. In Webb’s image, the spiny spiral arms are composed of many filaments in shades of orange, with prominent dark gray or black “bubbles,” and there is a blue haze near the core. In Hubble’s image, the spiral arms are a mix of bright blue star clusters, pink star forming areas and dark brown dust lanes, and the core is a pale yellow.

Two observations of the galaxy NGC 1300 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered, connected to a prominent diagonal bar structure. The galaxy’s two distinct spiral arms begin at the end of the bar and rotate counterclockwise. Together, the arm and bars form a backward S shape. In Webb’s image, the bar and spiral arms are composed of many filaments in shades of orange, and are anchored by its central region, which is circular and light yellow. In Hubble’s image, the spiral arms are a mix of bright blue star cluster and dark brown dust lanes, and the bar and core are a pale yellow.

Two observations of the galaxy NGC 1512 are split diagonally, with Webb’s observations at top left and Hubble’s at bottom right. The galaxy’s core is centered and circular, with two prominent dust lanes crossing the large diagonal bar structure appearing toward the top left and bottom right. The central bar is blue at top, looking like a gap until a closer examination shows it feeds a larger, oval shape that looks braided with many spiral arms. In Webb’s image, the spiral arms are composed of many filaments in shades of orange. In Hubble’s image the bar is a light pinkish-brown and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes.

Two observations of the galaxy NGC 3351 are split diagonally, with Hubble’s observations at top left and Webb’s at bottom right. The galaxy’s core is centered and the galaxy’s arms rotate clockwise and form a distinct outer ring. In Hubble’s image, the galaxy’s roughly horizontal bar structure is a pale yellow and the spiral arms are a mix of bright blue star clusters and dark brown dust lanes that form half of the large circular ring. In Webb’s image, the spiral arms form the other half of the large ring, which is made of many filaments in shades of orange. They are anchored by its central region, a hazy blue bar, connected to the central core. The core has a small orange oval around a more circular light yellow oval, with a blue dot at its center.

the first ever image of the entire earth and moon together, taken by voyager 1 in 1977

A historic image showing Earth and the Moon together for the first time, captured by NASA's Voyager 1 spacecraft in 1977. The bottom of the image features Earth, partially illuminated, with its blue oceans and white clouds visible against the blackness of space. Above and to the left, the Moon appears as a smaller, dimmer crescent, emphasizing the vast distance between the two celestial bodies. This photograph, taken just 13 days after Voyager 1’s launch, offers a profound perspective of our planet and its natural satellite, floating together in the cosmic void.
