The European Space Agency’s Euclid mission has scouted out the three areas in the sky where it will eventually provide the deepest observations of its mission.

In just one week of observations, with one scan of each region so far, Euclid already spotted 26 million galaxies. The farthest of those are up to 10.5 billion light-years away.

In the coming years, Euclid will pass over these three regions tens of times, capturing many more faraway galaxies, making these fields truly ‘deep’ by the end of the nominal mission in 2030.

The first glimpse of 63 square degrees of the sky, the

On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web.

Happy 2,000,000,000,000th, ICESat-2! NASA's Earth-observing laser in orbit passed a milestone on March 9 at 12:51 p.m. EDT - 16:51:00.268 UTC, to be precise - as its laser instrument fired for the 2 trillionth time and measured clouds off the coast of East Antarctica. ICESat-2's instrument, the Advanced Topographic Laser Altimeter System (ATLAS), uses rapid pulses of green laser light and

Life may not have begun with a dramatic lightning strike into the ocean but from many smaller "microlightning" exchanges among water droplets from crashing waterfalls or breaking waves. New research from Stanford University shows that water sprayed into a mixture of gases thought to be present in Earth's early atmosphere can lead to the formation of organic molecules with carbon-nitrogen b

NASA's Scientific Balloon Program has returned to Wanaka, New Zealand, for two scheduled flights to test and qualify the agency's super pressure balloon technology. These stadium-sized, heavy-lift balloons will travel the Southern Hemisphere's mid-latitudes for planned missions of 100 days or more. Launch operations are scheduled to begin in late March from Wanaka Airport, NASA's dedicated

In 2022, Randall Pietersen, a civil engineer in the U.S. Air Force, set out on a training mission to assess damage at an airfield runway, practicing "base recovery" protocol after a simulated attack. For hours, his team walked over the area in chemical protection gear, radioing in geocoordinates as they documented damage and looked for threats like unexploded munitions. The work is standar

AeroVironment (AV), a prominent player in the defense technology sector, has earned a key contract from the Defense Innovation Unit (DIU) aimed at fast-tracking the deployment of autonomous precision-strike drones. As part of its push into a critical segment of the defense industry, AV secured an Other Transaction Authority (OT) award from DIU under Project Artemis. This initiative is desi

Bone and muscle deterioration, radiation exposure, vision impairment - these are just a few of the challenges space travelers face on long-duration missions, even before considering the psychological toll of isolation. As US astronauts Butch Wilmore and Suni Williams prepare to return home after nine months aboard the International Space Station (ISS), some of the health risks they've faced
