Solar wind – charged particles from the Sun – pervades our solar system, but the exact mechanism behind it remains murky. Now ESA’s Solar Orbiter spacecraft has observed previously unknown tiny flares on the Sun’s surface spewing plasma into space.

In a scary first, scientists have discovered a 2021 solar eruption so large that it was, for the first time, detected simultaneously on Earth, the Moon, and Mars, highlighting the radiation dangers posed by such events to deep space travelers.

In an historic experiment, ESA has made a controlled reentry of its Atmospheric Dynamics Mission-Aeolus (ADM-Aeolus) satellite in a maneuver designed to reduce the risk of such end-of-life events creating space debris or fragments reaching the ground.

NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be forming.
-
After focussing on an asteroid that was struck in 2022 by a half-tonne NASA robotic probe traveling over seven times faster than a bullet, the Hubble Space Telescope has detected a swarm of 37 boulders that were dislodged by the impact.

According to a study by Astrostrom for ESA, future Moon bases could be powered by a giant space butterfly called the Greater Earth Lunar Power Station (GEO-LPS) covered with solar panels made from lunar materials beaming microwaves to the surface.

Collectors of trading cards are always hunting for rare shiny variants – and now astronomers have found the exoplanet equivalent. The shiniest planet ever found, LTT9779 b, is an ultra-hot, cosmic disco ball thanks to clouds made of glass and titanium.

After 27 years and 117 missions, ESA's heavy-lift Ariane 5 rocket has launched into retirement with the successful lift off of Flight VA261 on July 5, 2023 at 22:00 GMT from the Centre Spatial Guyanais (CSG) in French Guiana.

ESA's Euclid mission to map the universe and learn more about dark energy and dark matter is on its way. On July 1, 2023 at 5:12 pm CEST the space telescope lifted off from Cape Canaveral Space Force Station in Florida atop a SpaceX Falcon 9 rocket.

It may seem dangerous, but just in case future astronauts might have a yen for fries on a sojourn into space, ESA and the Aristotle University of Thessaloniki are investigating whether potatoes will fry ok in zero gravity or end up an undercooked mess.

Saturn’s moon Enceladus is famous for its plumes that spray water into space. Now the James Webb Space Telescope has watched the biggest known plume so far, spanning thousands of miles, and studied how they feed a huge water “donut” around Saturn.

When ESA's Juventas CubeSat lands on Dimorphos to assess the aftermath of last year's spectacular collisions with NASA's DART spacecraft, its GRASS instrument will directly measure the asteroid's gravitational pull, which is a millionth that of the Earth.
