The far side of the Moon seen from Artemis II, revealing a heavily cratered surface that is lit from the right side of the picture. The terminator runs from the bottom middle to the left middle, and craters along that line are sharper in detail.

#PPOD: In this photo taken on April 6, 2026, a portion of the Moon’s far side is seen along the terminator—the boundary between lunar day and night—where low-angle sunlight casts long shadows across the surface. 🧪 🔭

El cometa 2025 R3 PANSTARRS será visible a simple vista en abril Un cometa llamado C/2025 R3 PANSTARRS es visible ya desde la Tierra con tan solo unos prismáticos. Las próximas semanas el cometa crecerá en brillo y tamaño conforme se acerque al Sol.

A lo largo de las próximas semanas, se mostrará moviéndose noche tras noche prácticamente paralelo al horizonte. @joseptrigo.bsky.social (@ice-csic.bsky.social @ieec.cat) nos cuenta más:

Artemis II crew reflects on historic mission before splashdown on Friday The four astronauts said they were returning to Earth with "so many more pictures, so many more stories".

Artemis crew returning to Earth with 'all the good stuff' from Moon discoveries. 🔭 🧪 www.bbc.co.uk/news/article...

NASA ID: art002e009286 art002e009286 (April 6, 2026) – As the Artemis II crew came close to passing behind the Moon and experiencing a planned loss of signal, they captured this image of a crescent Earth setting on the Moon’s limb. The edge of the visible surface of the Moon is called the “lunar limb.” Seen from afar, it almost looks like a circular arc – except when backlit, as in other images captured by the Artemis II crew. In this photo, the dark portion of Earth is experiencing nighttime, while Australia and Oceania are in the daylight. In the foreground, the Ohm crater is visible, with terraced edges and a flat floor interrupted by central peaks. Peaks such as these form in complex craters when the lunar surface is liquified on impact, and the liquefied surface splashes upward during the crater’s formation. Date Created:2026-04-06

The lunar surface fills the frame in sharp detail, as seen during the Artemis II lunar flyby, while a distant Earth sets in the background. This image was captured at 6:41 p.m. EDT, on April 6, 2026, just three minutes before the Orion spacecraft and its crew went behind the Moon and lost contact with Earth for 40 minutes before emerging on the other side. The dark portion of Earth is experiencing nighttime, while on its day side, swirling clouds are visible over the Australia and Oceania region. In the foreground, Ohm crater shows terraced edges and a relatively flat floor marked by central peaks — formed when the surface rebounded upward during the impact that created the crater.

A landscape at night. The silhouette of the Rocky Mountains spans the bottom of the frame, with houselights nestled in the foothills. There are thin clouds with some stars showing through. On the right side is a multicolored meteor visible through the clouds. The tail is red, the body yellow/green.
