HiPOD: About a Pedestal Crater

The objective of this observation is to examine a pedestal crater here in Deuteronilus Mensae. A pedestal crater is when the ejecta from an impact settles and is more erosion-resistant than the surrounding terrain.

Image cutout shows a pedestal crater on the surface of Mars. The ejecta blanket from the original impact is still visible around the crater, because it was more resistant to erosion than the surrounding terrain. A closeup of the impact crater. The crater rim is very eroded and there are numerous large boulders around the crater.

Remastered Voyager 2 images show Uranus's moon Miranda. Its fractured surface suggests a past liquid water ocean may be slowly freezing beneath the ice. This makes Miranda a significant target in the search for water and potential life.

Hey Martians, did I mention we now also have a video of epic Phobos passing over a Martian dust storm near Pavonis Mons? 🌪️🌋🥔

This is the most detailed map yet of dark matter in the universe, based on JWST observations of 800,000 galaxies.

The background image shows those galaxies in infrared light. Yellow indicates the location of dark matter, inferred from its gravitational pull. 🧪🔭

This amazing pic by Matteo Dunchi features the Andromeda Galaxy (M31), rising over the Italian Alps in July 2015.

Although M31 appears in the sky as a faint and fuzzy blob to the unaided eye, its light is about 2.5 Myr old, making it likely the oldest...

Shadowy Italian Alps peaks below a deep inky-blue sky full of sharp stars. Andromeda glows softly in the middle as a big oval patch, brighter at the center, fading into a hazy ring.

We’re supposed to believe this is a domestic terrorist attacking ICE with a gun
A photo of the man murdered by ICE today, just before the shooting. He’s standing and holding a phone in his right hand and holding his empty left hand to the sky and looking behind him at a woman running away while an ICE agent closes in on him from the front. On the ground behind the man is a woman that the victim will soon try to help, leading several ICE agents to attack him and pin him to the ground, before shooting him several times.

We're celebrating the 96th revolution around the Sun of astronaut Buzz Aldrin. As the Lunar Module pilot on Apollo 11, he was one of the first two humans to walk on the Moon and helped carry out scientific experiments that expanded our understanding of space.

It is thought that Jupiter's moon Europa contains a vast underground ocean, bigger than all Earth's oceans combined. For yrs, we've dreamed it might teem with life thanks to chemical energy from hot rocks. But a fresh study has weakened that idea.🔭

2 NEW epic images of Phobos over Mars just released by @esa.int Mars Express

This view is especially striking, with Phobos between the Tharsis volcanoes and Noctis Labyrinthus–Valles Marineris

A wide view of the planet Mars fills the frame, shown as a curved, rust-colored world against black space. The bottom edge fades into darkness, marking the planet’s night side, while the upper portion is brightly lit by sunlight. Near the right side are three large, round volcanic mountains of the Tharsis region, each with a wide circular base and a darker central caldera, resembling shallow craters pressed into the surface. North of these volcanoes, stretching almost vertically across the upper right half of the planet, lies Noctis Labyrinthus and Valles Marineris: an immense system of deep canyons and fractured terrain that appears as pale, branching scars and cracks, partly softened by hazy, cloud-like atmospheric features. Near the center of the image, positioned between the volcanoes and the canyon system, a small dark oval appears against Mars’s surface. This is Phobos, one of Mars’s satellites. Its tiny size stands out sharply against the vast scale of the planet below.

Jacking up costs, surging unemployment, terrorizing communities, and millions spent gold-plating the Oval Office.

What's causing these weird blue flashes in the sky?

A new study suggests an extreme explanation: The most recent flash probably came from a giant star, 10x the mass of the Sun, being completely consumed by a black hole in just a few days. Ulp. 🧪🔭

This composite image features X-ray, ultraviolet, optical, and near-infrared data of the luminous fast blue optical transient (LFBOT) named AT 2024wpp. The transient is the bright spot at the upper right edge of its host galaxy, which is 1.1 billion light-years from Earth.

Astronomers are reporting evidence for a possible second kilonova event, but the case is not closed. In fact, this situation is much more complex.

Y'all the latest episode of the #Kilauea #eruption just went CRAZY. It looks like pressure built up enough to explode out the ground around the two existing vents (first few seconds), leading to a massive surge in lava fountaining.🌋🤯
