Last week, members of ESA’s astronaut class of 2022 embarked on their first overseas field trip. They visited NASA’s facilities at the Johnson Space Centre (JSC) in Houston, Texas, USA, to get familiar with the environment where they will spend a significant part of their training once assigned to a mission.

At nearly 14,000 feet, Maunakea is the tallest mountain in Hawai'i, and the second tallest on any island on Earth. Clouds often settle below the mountain's barren, dark-brown summit, making the site one of the best for astronomy in the world. At the summit, one can find several of the world's finest telescopes, including the W. M. Keck Observatory, a partnership between Caltech and the Uni

Helicity Space, a name that's beginning to resonate in the commercial space industry, recently heralded a significant advance in its quest to redefine space propulsion. The company has successfully secured a $5 million seed funding round, a move that not only underscores the industry's confidence in fusion technology but also marks a pivotal moment in space travel innovation. This round of

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA's Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. "The bright, steady gamma-ray glow of the Milky Way is punctuated by intense, days-long flares of n

Despite our many years spent observing the cosmos with ever-more powerful telescopes, there remains much to learn about the Milky Way. We cannot leave our galaxy to get a full outside view of its shape and properties, as we do when we study other galaxies. We are embedded within it, and so are limited to mapping the Milky Way from the inside out - and from a single vantage point. At the st

Like a celestial beacon, distant quasars make the brightest light in the universe. They emit more light than our entire Milky Way galaxy. The light comes from matter ripped apart as it is swallowed by a supermassive black hole. Cosmological parameters are important numerical constraints astronomers use to trace the evolution of the entire universe billions of years after the Big Bang. Quas
