Due to an ongoing commercial spacecraft attitude control issue, NASA and Katalyst Space announced Wednesday the LINK spacecraft will not capture or boost an agency satellite to a higher altitude to extend its science mission as planned.

Swift was launched in 2004 to study gamma-ray bursts, the most powerful explosions in the universe, and other cosmic objects and events. It was designed for a two-year prime mission. After 21 years of science operations, Swift’s low Earth orbit began to rapidly decay because of increased solar activity. NASA used this opportunity to advance U.S. spacecraft servicing technology, awarding a contract to Katalyst in September 2025 to mount a robotic servicing mission for Swift in less than a year.

The total solar eclipse over the 800 year old Burgos Cathedral from Spain. This final result contains much more data from the multiple exposures of the solar corona, even revealing the night side of the Moon.

Equipment: Canon 6D Mark II, Sigma 150-600mm lens.

Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its centre. The star, named S301, was detected with the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) and reaches speeds of 25 000 km/s (8% the speed of light) as it travels around the four-million-Solar-mass black hole. It comes closer to it than any other observed before, so close that it feels the effects of the black hole’s rotation.

This is 40 hours of imaging in OHS color palette from my backyard in Utah using a 10” Meade and ASI2600mm pro. Hope you like it so far. Still a little noisy…. Hopeful that I get more clear nights to finish this target.

A new study – guided by flyby images from ESA’s Hera asteroid mission – suggests that Mars’s small outer moon Deimos has been dramatically reshaped by a single violent asteroid impact.

This would account for its mysteriously smooth and youthful face: a thick layer of dust from the impact may have served as the planetary equivalent of cosmetic fillers.

This is a re-image of an observation we acquired in 2016 to measure dune mobility. This is a remarkable and rare example of ice-dune interaction, which can be seen as a modern analogue of the burial of the wind-driven, ice-rich sedimentary deposit under the North Polar layered deposits of Mars.

The Richat Structure appears as a giant "bull's eye" on a plateau in Mauritania in this mosaic, composed of images captured by the OLI (Operational Land Imager) on Landsat 9 and Landsat 8 on March 5 and March 6, 2026, respectively.

The 40-kilometer-wide (25-mile-wide) structure was initially thought to be an impact crater because large meteors can produce circular features on Earth’s surface.

However, researchers later showed that it is actually a deeply eroded geologic dome formed by the uplift of rock above an underground intrusion of igneous material. Over time, differing erosion rates among rock types in the exposed upper dome led to the development of circular ridges known as cuestas.

The orange and gray colors reflect differences in sedimentary and igneous rock types across the structure and the surrounding landscape.
