Some of the most dramatic events in the universe occur when certain stars die — and explode catastrophically in the process. When these star deaths, or supernovae, occur, their brightness can rival the light of a whole galaxy. The galaxy NGC 5468, shown in this Hubble image, has hosted a number of these supernovae the […]
Image: The Copernicus Sentinel-1 mission takes us over part of the Brazilian state of Mato Grosso deep in the Amazon interior. This image combines three separate radar images from the Copernicus Sentinel-1 mission taken about two years apart to show change in crops and land cover over time. Unlike images from satellites carrying optical or […]

A fine coffee froth does not last forever. The bubbles that make the milk light and creamy are eventually torn apart by the pull of gravity. But there is a place where foams have a more stable life – in the weightless environment of the International Space Station, bubbles don’t burst so quickly and foams […]
Video: 00:02:45 ESA’s first mission dedicated to investigating planets outside our solar system is scheduled for launch on a Soyuz rocket from the European spaceport in French Guiana on 17 December 2019. Cheops – Characterising ExOPlanet Satellite – will study known exoplanets that are orbiting bright stars. The aim is to obtain detailed information about […]
Four trillion satellite measurements, taken over four decades from 1981 to 2018, have been merged to create a continuous global record that will help to understand the science behind Earth’s climate. A paper published recently in Nature Scientific Data describes how this new dataset of global sea-surface temperature is one of the longest satellite climate […]

Video: 00:05:20 In a cleanroom in Ottobrunn, Germany, the latest Copernicus Sentinel satellite is ready for final testing before it is packed up and shipped to the US for liftoff next year. Designed and built to chart changing sea level, it is the first of two identical Sentinel-6 satellites that will be launched consecutively to […]

Image: The Orion spacecraft with European Service Module at NASA’s Plum Brook Station. The first Orion will fly farther from Earth on the Artemis I mission than any human-rated vehicle has ever flown before – but first it will undergo testing to ensure the spacecraft withstands the extremes of spaceflight. Here at NASA’s Plum Brook […]

Image: ‘Swage’ was the word of the day on Monday as ESA astronaut Luca Parmitano carried out the third spacewalk to service the cosmic ray hunting Alpha Magnetic Spectrometer AMS-02. Here Luca is suspended above Earth as he is moved to a second worksite to swage, or join, the instrument’s tubes to a new pump […]
