Ring Around Tabby’s Star

This illustration depicts a hypothetical uneven ring of dust orbiting KIC 8462852, also known as Boyajian’s Star or Tabby’s Star. Astronomers have found the dimming of the star over long periods appears to be weaker at longer infrared wavelengths of light and stronger at shorter ultraviolet wavelengths. To source

Copernicus Sentinel-1: radar vision for Copernicus

Video: 00:07:25 Meet Copernicus Sentinel-1  – this ground-breaking mission delivers continuous, all-weather, day-and-night imaging for land, ice and maritime monitoring.  Equipped with state-of-the-art C-band synthetic aperture radar (SAR), Sentinel-1 captures high-resolution data around the clock, in any weather, making it indispensable for detecting the subtle changes on Earth’s surface that remain hidden from the human eye.

Fly around Ares Vallis on Mars

Video: 00:04:30 Explore the immense power of water as ESA’s Mars Express takes us on a flight over curving channels, streamlined islands and muddled ‘chaotic terrain’ on Mars, soaking up rover landing sites along the way. This beautiful flight around the Oxia Palus region of Mars covers a total area of approximately 890 000 km², […]

New full Sun views show sunspots, fields and restless plasma

Zoom into Solar Orbiter’s four new Sun images, assembled from high-resolution observations by the spacecraft’s PHI and EUI instruments made on 22 March 2023. The PHI images are the highest-resolution full views of the Sun’s visible surface to date, including maps of the Sun’s messy magnetic field and movement on the surface. These can be […]

On This Day: Apollo 12 Lands on the Moon

On Nov. 19, 1969, astronaut Alan L. Bean, lunar module pilot for the Apollo 12 mission, begins to step off the ladder of the lunar module to join astronaut Charles Conrad Jr., mission commander, in a spacewalk. Conrad and Bean descended in the Apollo 12 lunar module to explore the moon while astronaut Richard F. […]

Space for Shore: Sentinel-1 reveals Arctic glacier retreat

As Arctic temperatures rise, marine-terminating glaciers—especially in places like Svalbard—are undergoing rapid retreat and intensified calving. The ESA-funded Space for Shore project utilises radar data from the Copernicus Sentinel-1 mission to provide precise, year-over-year insights into glacier retreat and calving intensity, particularly in areas like Kongsfjorden, where notable glaciers are experiencing significant retreat.

Proba-3’s journey to see the Sun’s corona

Video: 00:04:31 The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, […]
