A few hours ago, NASA’s ESCAPADE (Escape and Plasma Acceleration and Dynamics Explorers) twin probes were launched atop a Blue Origin New Glenn rocket, which accomplished its mission, called NG-2. One goal for Blue Origin was to land the first stage, which was a successful one just over 9 minutes after launch. After approximately 33 minutes, the probes, named Blue and Gold, separated from the rocket’s second stage and began a long journey to Mars to study its magnetosphere and the Sun’s impact on the red planet.

The cosmic wave in red and blue, with stars above the galactic disk in red and the ones below it in blue

An article published in the journal “Astronomy and Astrophysics” reports the results of a study that provides evidence that a sort of giant cosmic wave is crossing the Milky Way, propagating from the center outward from the galactic disk, causing a corrugation. A team of researchers led by Eloisa Poggio of the Italian National Institute for Astrophysics used data collected by ESA’s Gaia space probe to map the motions of thousands of young giant stars and Cepheids within the corrugation, reconstructing the wave that generates them. The cause may be the aftermath of an ancient collision with a dwarf galaxy, but follow-up studies are needed to assess this and other possible explanations.

A little while ago, three space probes were launched atop a Falcon 9 rocket from the Kennedy Space Center. After approximately one hour and 23 minutes, they successfully separated from the rocket’s final stage within about 13 minutes and set off on a course that will take them to the area known as L1 (Lagrange 1), about 1.5 million kilometers from Earth, where they will begin their scientific work studying various aspects of space weather.

Arcadia Planitia on Mars

ESA has published a photo of the Arcadia Planitia region on Mars captured by its Mars Express space probe’s High Resolution Stereo Camera (HRSC). This is an interesting region from a geological point of view because it’s northwest of the large volcanoes of Tharsis, the largest in the entire solar system, and traces of ancient lava flows are still visible. It could be important for the exploration of the red planet if confirmation of the presence of frozen water right under the surface were to arrive.

The Sun observed across eight different wavelengths by the Solar Orbiter space probe

ESA has released the first information, including the first images, of the Sun’s South Pole, captured between March 16 and 17, 2025, by the Solar Orbiter space probe, a mission operated in collaboration with NASA. Three of the scientific instruments on board made it possible to observe that area in different electromagnetic bands: Polarimetric and Helioseismic Imager (PHI), Extreme Ultraviolet Imager (EUI), and Spectral Imaging of the Coronal Environment (SPICE). The Sun’s poles aren’t visible from Earth, and Solar Orbiter is observing them as never before. The first observations have already revealed some surprises.
