As a dying, Sun-like star puts on a stunning display of light, shadow, and dust, Hubble is watching it unfold. Hubble’s sharp vision reveals intricate details of the enigmatic Egg Nebula’s remarkable structure: https://news.stsci.edu/4aw90ay
In the image center, an opaque oval cloud of gray gas aligned from 1 o’clock to 7 o’clock hides a star. Two strong beams of light from the star emerge from large holes in both sides of the cloud, forming narrow cones extending toward 10 o’clock and 4 o’clock. The central cloud is surrounded by concentric, wispy shells of gas illuminated by the star’s light. The shells reflect extra light where they’re hit by the twin beams. A crowd of smaller stars with cross-shaped spikes over them surrounds the nebula on a black background.

It still seems unreal to me that humans will soon be flying back to the moon! They will be returning to Earth at a speed of 40.000 km/h, the fastest ever reentry of a crewed spacecraft.

This remastered video shows a similar reentry from the #Artemis 1 mission back in 2022 at 9x speed. 🔭🧪

Cool, wind-shaped rocks on Mars photographed yesterday.
Sand, dust, and pebbles in the foreground grade away to more solid rock displaying curious, left–right-trending ridges that are (I presume) the result of wind erosion.

NASA Study: Non-biologic Processes Don’t Fully Explain Mars Organics

In a new study, researchers say that non-biological sources they considered could not fully account for the abundance of organic compounds in a sample collected on Mars by Curiosity.

ESA astronaut Sophie Adenot speaking with French President Emmanuel Macron With the 2026 Winter Olympics officially opening today, the Copernicus Sentinel-2 mission brings us a striking view of northern Italy, highlighting several key Olympic venues. This view is taken from a Mars Express flyover video of Flaugergues Crater on Mars. It shows the final scenes of the video, which culminates with a bird’s-eye view of the 240-km-wide crater itself. Technicians work at the bottom of the launch pad pm Ariane 6 flight VA267 in French Guiana, 27 January 2026. This launch will be the first to fly with four boosters, doubling liftoff thrust for the launcher, and see Ariane 6 take satellites for Amazon’s Leo constellation to orbit
