SpaceX has completed testing of Version 2 of its Starship launch system and is preparing for Version 3. Meanwhile a small asteroid was discovered just days before passing close to Earth, and scientists have identified unexpected complex molecules on Saturn’s moon Enceladus. This Week in Space

The director of the Israel Space Agency concludes his tenure, a Chinese experiment successfully simulates a lunar landing, the upgraded configuration of the Vulcan rocket lifts off for the first time, and a promising exoplanet is revealed to be a cosmic disappointment.

A new Israeli Space Center initiative, policies shift around private space stations, discoveries of complex molecules in a planet-forming system, and a veteran astronaut retires. This Week in Space

Observations from the James Webb Space Telescope point to the existence of a Saturn-like planet orbiting Alpha Centauri A — a Sun-like star in the nearest stellar system to Earth.

Disappointment as the continuation of the Israeli experiment to photograph sprite lightning from space comes back empty-handed, another delay for Boeing’s spacecraft, a travel record on Mars, and the birth of new planets. This Week in Space

For the first time, researchers have documented the very beginning of planet formation around a young, distant star—a discovery that could shed new light on the early history of our own Solar System.

The U.S. Air Force has canceled an intriguing space experiment, while new research reveals surprising details about the ocean beneath Enceladus’s icy surface. This Week in Space

Researchers and engineers from Israel are advancing a mission to search for signs of life on Jupiter’s moon Europa

Using the James Webb Space Telescope, astronomers have identified a previously unknown moon orbiting Uranus. With an estimated diameter of just ten kilometers, this small celestial body increases the known count of Uranian moons to 29.

One of the primary obstacles on the path to settling Mars is its frigid climate. A new study proposes addressing this issue by triggering a greenhouse effect.

Molecules identified in a distant planet’s atmosphere form on Earth only through biological activity.

NASA is initiating layoffs as part of a cost-cutting plan. Meanwhile, a powerful new space telescope has launched, 128 new moons have been discovered orbiting Saturn, and the Voyager spacecraft are getting a life-extending strategy. This Week in Space.

The private lunar lander overturned upon landing, Starship exploded in space, spacecraft went missing, and a European launch was successful. This Week in Space.

Firefly’s uncrewed lander has completed a soft landing and will primarily investigate the Moon’s geology and surface composition.

Scientists analyzing samples from the asteroid Bennu have identified thousands of organic molecules, including the building blocks of proteins and genetic material. “This increases the likelihood of finding life elsewhere,” researchers say.

A spacecraft sets a new record for a Sun flyby, NASA privatizes space communication, a new study reveals the Moon’s age, educational astronomy, and a unique ring. This Week in Space

Marking 90 years since the birth of Carl Sagan, a trailblazer in planetary science and astrobiology, who became an iconic advocate for science in the media and the public sphere through popular books and a successful TV series.

For years, researchers have been puzzled by peculiar findings regarding Uranus’s magnetic field. A new study suggests these findings may have been atypical rather than representative of the planet’s usual characteristics.

Communication satellites featuring Israeli developments, record crowding in space, and a surprising new volcano.

A major deal for ISI, China’s plans to bring samples from Mars, the Polaris Dawn mission underway, NASA’s space sail project, and a farewell to an old rocket. This Week in Space

If the universe is infinite and filled with shining stars, we might expect a continuously bright sky. Why then is it dark at night?

Evidence of water-containing crystals on the Moon, a deep diamond layer in Mercury, and looming shutdown threat to the Chandra X-ray Observatory.

A Miyake event—an intense and rare solar storm—can have lasting effects on both nature and humanity

Sample collection from the far side of the moon, Boeing launches a leaky spacecraft, and a particularly intriguing planet is found.
