From left to right, NASA astronauts Andre Douglas, Victor Glover, and Christina Koch, CSA (Canadian Space Agency) astronauts Jenni Gibbons, NASA astronaut Reid Wiseman, and CSA astronaut Jeremy Hansen pose for a photo before the Artemis II crew proceed to a media event on March 27, 2026. Douglas and Gibbons are the backup crew members for the mission; they would join the crew if a NASA or CSA astronaut, respectively, is unable to take part in the flight.

Artemis II is NASA’s first crewed mission under the Artemis program and will launch from the agency’s Kennedy Space Center in Florida. It will send Wiseman, Glover, Koch, and Hansen on an approximately 10-day journey around the Moon. Among other objectives, the agency will test the Orion spacecraft’s life support systems for the first time with people and lay the groundwork for future crewed Artemis missions.

This collection of images from NASA’s Chandra X-ray Observatory and other telescopes contains regions where stars are forming. Often nicknamed “stellar nurseries,” they are cosmic gardens from which stars – not plants – emerge from the interstellar soil of gas and dust.

Even if the conflict in the Middle East ends today, higher fuel, fertiliser and pesticide prices will lead to a food shock in the coming months. There is no easy way out, but accelerating the net-zero transition will help prevent future shocks

Is gravity the same over the surface of the Earth?

Powerful X-rays from the nearby naked-eye star Gamma Cas mystified astronomers for decades. Now, a new observatory reveals that they come from its white dwarf companion.

The post White Dwarf Discovered Gobbling Material from Gamma Cassiopeiae appeared first on Sky & Telescope.

Infections of the BA.3.2 variant of the COVID-causing coronavirus are still at very low levels, but experts are concerned it may be resistant to immunity from vaccines or prior infection

It’s amazing how much one movie can act as a cultural touchpoint for an entire topic - even a topic as serious as defense of a planet. Popular media consistently use the 1998 movie Armageddon as a reference when talking about how we would destroy a civilization-ending asteroid. That’s despite the movie’s glaring scientific flaws, not the last of which is the likely size of the rogue comet that threatens the Earth. Planetary defense researchers at MIT were recently interviewed by the university’s media department as part of their “3 Questions” series. One of the most important takeaways is that the size of any likely planetary impactor in our lifetime is going to be much smaller than the kilometer-sized behemoth that did in Bruce Willis’ character - but we could face a threat from a handful of them before the end of the century.

NASA’s nuclear Mars mission, the Iran war’s carbon fallout, the looming climate cost of rebuilding and a hopeful new Lyme vaccine

Every green leaf on Earth does something remarkable, it absorbs visible light for photosynthesis but reflects near-infrared light back into space, creating a distinctive spectral signature that could in principle be spotted from across the Galaxy. It's called the vegetation red edge, and it may be our best hope of detecting life on distant worlds. Now a new study has tackled one of the biggest obstacles to using it, the messy, patchy reality of real planets with real clouds.

Mars today is a frozen, barren world where liquid water can briefly appear on its surface but evaporates almost instantly in the thin atmosphere, unable to persist in any meaningful quantity. But a handful of pale, bleached rocks spotted by NASA's Perseverance rover are telling a very different story about the planet's past, one of tropical downpours, sodden landscapes, and conditions that might once have been hospitable to life.
