NASA (National Aeronautics and Space Administration) Administrator Jared Isaacman classified the 2024 Starliner crewed flight as a major failure, citing significant shortcomings in both Boeing's development and NASA's own program oversight.

The spacecraft experienced multiple helium leaks in its propulsion system and subsequent intermittent thruster failures, forcing astronaut Butch Wilmore to take manual control during the tense docking sequence with the station.

Isaacman stated the most troubling failure was in decision-making, which could create a culture incompatible with human spaceflight, promising leadership accountability and a future uncrewed test flight for the Starliner vehicle.

A University of Toronto team led by David Li used multiple observatories to identify Candidate Dark Galaxy-2 (CDG-2), a faint galaxy that appears to be almost entirely dominated by dark matter.

Hubble Space Telescope imaging revealed four globular clusters, which account for 16% of the galaxy's visible content, while preliminary analysis suggests 99% of its mass is dark matter.

According to Francine Marleau, ESA's (European Space Agency) Euclid mission demonstrates a unique capability to detect new low-surface-brightness galaxies, providing crucial data on these elusive objects and their cosmic role.

NASA teams at Kennedy Space Center initiated the Artemis II wet dress rehearsal, a comprehensive test simulating the final countdown procedures for the first crewed mission of the ambitious Artemis program.

The procedure involves loading over 700,000 gallons of cryogenic liquid hydrogen and oxygen into the SLS (Space Launch System) rocket and running the terminal count down to T-33 seconds before cutoff.

Launch Director Charlie Blackwell-Thompson confirmed the test validates launch day protocols, including automated system takeovers and contingency scenarios, ensuring all systems can perform flawlessly under real-world launch conditions for the crew.

An international team led by Jorge Zavala at UMass Amherst discovered a population of dusty, star-forming galaxies that existed just one billion years after the Big Bang, challenging current cosmic models.

The team used the Atacama Large Millimeter/submillimeter Array (ALMA) to identify 400 bright galaxies, then used James Webb Space Telescope near-infrared observations to pinpoint approximately 70 fainter candidates.

Zavala suggests these galaxies link young, ultrabright galaxies with older, quiescent ones, implying star formation occurred much earlier in the universe's evolution than our current astronomical models of cosmic history predict.

University of Arizona researchers led by Yongda Zhu studied how intense radiation from active supermassive black holes, known as quasars, can significantly slow down star formation in many neighboring galaxies.

Using the James Webb Space Telescope, the team measured weaker O III gas emissions—a tracer for recent star formation—in galaxies within a million-light-year radius of quasar J0100+2802.

Zhu states this is the first evidence of this radiation impacting the universe on an intergalactic scale, suggesting supermassive black holes played a much larger role in galaxy evolution than previously thought.
