25 years of Copernicus
Video: 00:05:05
25 years ago, Copernicus set out to transform the way we see our planet. It is the largest environmental monitoring programme in the world. Learn more about the Copernicus programme and the Sentinel satellite missions developed by ESA.
NASA’s Europa Clipper Taking “Message in a Bottle” to Jupiter
NASA believes in getting the public excited about space, and they’re carrying on this tradition by recently announcing that space fans from around the world can travel to Jupiter with the Europa Clipper mission. Though, not literally, but by adding their names to a microchip for the “Message in a Bottle” campaign that will also contain “In Praise of Mystery: A Poem for Europa”, which is an original poem by U.S. Poet Laureate Ada Limón.
Is it Time for a New Definition of “Habitable?”
Things tend to move from the simple to the complex when you’re trying to understand something new. This is the situation exoplanet scientists find themselves in when it comes to the term ‘habitable.’ When they were discovering the first tranche of exoplanets, the term was useful. It basically meant that the planet could have liquid water on its surface.
Missed the Mars Livestream? Here's the Video
When a mission to Mars reaches 20 years of service, that’s definitely reason to celebrate. ESA’s Mars Express celebrated by airing the first-ever livestream of images, sent directly from the Visual Monitoring Camera (VMC) on board the spacecraft. For an hour, it sent back images from the Red Planet in as close to real-time as the speed of light would allow.
JWST Shows How the Early Universe Was Furiously Forming Stars
We can gaze out into regions in our neighbourhood of the Milky Way and find orgies of star birth. The closest region is in the Orion nebula, where astronomers have identified more than 700 young stars. They range from only 100,000 years—mere infancy for a star—to over a million years.
NASA concerned SpaceX’s Starship schedule could delay moon landing

A senior NASA official raised concerns Wednesday that “difficulties” with SpaceX’s development of the huge new Starship rocket could delay the Artemis program’s first moon landing with astronauts from late 2025, a mission that will use a derivative of the Starship vehicle to ferry a two-person crew to and from the lunar surface.
Earth's highest, coldest, rarest clouds are back. How to see the eerie 'noctilucent clouds' this summer.
Look North as the stars appear in June and July to have a chance of seeing rare noctilucent (or 'night-shining') clouds with the naked eye.
James Webb Space Telescope spots faintest galaxy yet in the infant universe (photo)
Astronomers using NASA's James Webb Space Telescope have confirmed the faintest galaxy yet seen in the early universe, a curious object that lies 13.3 billion light-years from Earth.
Satellite photos show US East Coast engulfed by smoke from Canadian wildfires
The U.S. Northeast woke up to a "horribly smoky day" on Wednesday (June 7) as a low-pressure system funnels toxic smoke from wildfires in Canada across the Atlantic Coast.

Owen Jay Gingerich, 1930–2023
Owen Jay Gingerich, well-known historian of astronomy and contributor to Sky & Telescope for more than half a century, died on May 28, 2023.
NASA's sun-kissing Parker Solar Probe finds source of 'fast' solar wind
Using data collected by NASA's sun-touching Parker Solar Probe, scientists have tracked the "fast" solar wind back to showerhead-like funnels generated by coronal holes.
SLS Could Launch a Sample Return Mission to Phobos and Deimos
NASA’s next colossal rocket, the Space Launch System (SLS), recently had its first successful flight back in November after years of development. Much of that development was done by aerospace contractors like Northrop Grumman and Boeing, so it is a good bet that engineers at those companies want the SLS to be seen as a success. One measure of its success will be how many missions it manages to help launch successfully – the more missions, the better. To help plan out some of those missions, a pair of Boeing engineers wrote a paper describing an outline of a sample return mission to Phobos and Deimos. And, of course, it would be launched by the SLS.
James Webb Space Telescope Uncovers Hundreds of Galaxies in Early Universe
In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.

Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.
25 times Copernicus made the headlines
Twenty-five years ago, Copernicus set out to transform the way we see our planet. Now, well established as the largest environmental monitoring programme in the world, it returns a whopping 16 terabytes of high-quality data every single day. To mark a quarter-century of European success in space, we look back at a selection of 25 Copernicus highlights.

Dark matter atoms may form shadowy galaxies with rapid star formation
Dark matter, the invisible material that makes up the vast majority of the universe's mass, may collect itself to form atoms, a new simulation shows.
