Find out why the cones in Ulysses Colles, on the edge of Tharsis, are rare evidence of explosive eruptions on Mars. We report what scientists say about these Strombolian traces, why there are few of them on the Red Planet, and how they compare them with a volcanic field in northern Arizona. The Mars Reconnaissance Orbiter and Landsat 8 satellites reveal lava flows, vents, and grabens.
Learn how Hubble and Euclid combined a wide frame and high resolution in the new ESA/Hubble Picture of the Month of the Cat’s Eye Nebula (NGC 6543), and what layers of gas, jets, and rings—about 4,400 light-years away according to Gaia—reveal about the finale of Sun-like stars and a background packed with distant galaxies.
Find out why the solar panel deployment test on the ALTIUS satellite is crucial for future measurements of ozone and trace gases. We explain what ESA’s mission does differently with limb sounding, why it matters for tracking ozone-layer recovery, and how Belgium and partners are pushing the project toward the planned 2027 launch.
Here’s an overview of NASA’s Artemis program changes: Artemis II targets April 2026 after repairs, Artemis III in 2027 becomes an orbital verification with SpaceX and Blue Origin landers and xEVA suits, and the first landing is planned for 2028, with an ambition of annual missions. Find out what changes and why NASA is standardizing SLS and Orion.
Find out when totality begins on March 3, 2026 and why the Moon turns copper-red during a total lunar eclipse. We provide NASA’s timings in UTC, a visibility map (Pacific and the Americas, not Europe), and practical tips for observing and photographing—plus a reminder about the Venus–Saturn conjunction on March 8.
Find out how ESA's mobile laboratory on wheels at ESTEC tests 5G New Radio links with satellites in low orbit, why the Q-band and reliable „handovers“ are key, and what Europe expects from the EuCNC & 6G Summit in Málaga in early June 2026. We also provide background on ESA's Space for 5G/6G & Sustainable Connectivity programme.
