The space of night is infinite,
The blackness and emptiness
Crossed only by thin bright fences
Of logic

Smile: cleanroom to space

Mon, 06/01/2026 - 11:00am
Video: 00:03:24

Smile successfully launched from Europe’s Spaceport in French Guiana on 19 May 2026.

This timelapse captures the excitement and precision of launch operations as the spacecraft begins its journey to study the connection between the Sun and Earth.

Smile (the Solar wind Magnetosphere Ionosphere Link Explorer) is an international space science mission designed to investigate how the solar wind interacts with Earth's magnetosphere. By observing these dynamic processes from space, Smile will help scientists better understand space weather and its effects on our planet's magnetic environment.

Webb reveals black hole that formed before its galaxy

Wed, 05/27/2026 - 11:00am

Using the unprecedented imaging and spectroscopic power of the NASA/ESA/CSA James Webb Space Telescope, researchers have mapped the motion and composition of gas orbiting a black hole in the centre of Abell2744-QSO1, a tiny galaxy more than 13 billion light-years away. The results suggest that the 50-million-solar-mass black hole predates its host galaxy, possibly forming within the first second of the Big Bang, and must have been immense from the start.

Insights into Earth’s molten outer core from space

Thu, 05/21/2026 - 9:00am

The liquid iron in Earth’s outer core doesn’t always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain better insight into the dynamics at the centre of our planet.

Greenlight for next two ESA Scout missions

Wed, 05/20/2026 - 9:00am

The European Space Agency is expanding its growing fleet of Earth-observing science Scout missions with the selection of two new satellites: Hibidis and SOVA-S.

Chosen from four final competing concepts, these missions will tackle very different but equally pressing scientific questions – from biodiversity below forest canopies to the effects of atmospheric gravity waves high above Earth.

Smile launch highlights

Tue, 05/19/2026 - 4:00am
Video: 00:04:00

ESA’s Smile satellite launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on at 04:52 BST / 05:52 CEST (00:52 local time) on 19 May 2026.

Smile flew to space on Vega-C flight VV29. At 35 m tall, a Vega-C weighs 210 tonnes on the launch pad and the rocket used three solid-propellant-powered stages to take Smile to orbit before the fourth liquid-propellant stage took over for a precise drop-off around Earth.Smile (the Solar wind Magnetosphere Ionosphere Link Explorer) is a joint mission between the European Space Agency (ESA) and the Chinese Academy of Sciences (CAS).

Smile will use four science instruments to study how Earth responds to the solar wind from the Sun. In doing so, Smile will improve our understanding of solar storms, geomagnetic storms and the science of space weather.

Preparing Smile for space

Video: 00:04:42

Before Smile can begin studying how Earth responds to the streams of particles and bursts of radiation from the Sun, the spacecraft had to complete an extraordinary journey here on Earth.

Follow the mission through its final launch preparations at Europe’s Spaceport in French Guiana, from fuelling and encapsulation inside its protective fairing, to meeting the rest of the Vega-C rocket that will take it to space.

Smile is flying to space on Vega-C flight VV29. At 35 m tall, Vega-C weighs 210 tonnes on the launch pad and the rocket will take Smile to orbit with three solid-propellant-powered stages before the fourth liquid-propellant stage takes over for a precise drop-off around Earth.

Smile (the Solar wind Magnetosphere Ionosphere Link Explorer) is a joint European-Chinese mission to study the interaction between the solar wind and Earth’s magnetic environment from a unique highly elliptical orbit. During the next three years, it will go high above the North Pole every two days to collect X-ray and ultraviolet images of Earth’s magnetic shield and the northern lights.
