One week today, the first of a new generation of weather satellites will take to the skies. The Meteosat Third Generation system is the most complex and innovative meteorological satellite systems ever built. It will bring new capabilities to monitor weather, climate and the environment from space like never before – promising to further bolster Europe’s leadership in weather forecasting.
There simply isn't enough normal matter to account for the amount of gravitational force needed to hold the universe together, meaning dark matter must be prevalent.
Orion is on track to return home, where it will splash down in the Pacific Ocean on Dec. 11, if all goes according to plan.
Some of the small missions deployed from Artemis 1 will go on to do great things, while others remain silent.
We GPS all the time but how does it work and why was it invented? Here we explore this vital space-based technology.
The life-support system for generating livable conditions inside the Orion capsule is not being fully tested during the spaceship's debut uncrewed mission Artemis 1.
At twin ground-breaking ceremonies today in South Africa and Australia, project leaders formally marked the start of construction on what will be the largest radio telescope ever built. Dubbed the Square Kilometer Array Observatory (SKAO) – referring to the total area the antennas and dishes will cover when complete – the telescope is not a single detector but rather a collection of them, connected across two continents using a technique known as interferometry (the same technique used by the Event Horizon Telescope, which took the first ever photograph of a black hole in 2019).
The on-again, off-again detection of phosphine in the atmosphere of Venus appears to be off-again – for now. The latest study, based on data from the SOFIA telescope, reveals that the flying observatory didn’t see any signs of phosphine. According to the results, if there is any phosphine present in Venus’s atmosphere at all, it’s a maximum of about 0.8 parts per billion, much smaller than the initial estimate.
Open star clusters are groups of stars in loosely-bound gravitational associations. The stars are further apart than the stars in their cousins, the globular clusters. The weak gravity from the loose clusters means open clusters take on irregular shapes. They usually contain only a few thousand stars.
The growing population of communication satellites such as Starlink and OneWeb is posing challenges for Earth-based astronomy facilities. Since such constellations will not be going away soon, astronomers want to find ways to work around the issue.
If space colonization is in our future, we’ll have to use the resources available there. But we won’t be able to bring our established industrial methods and processes from Earth into space. Transporting heavy mining machinery to the Moon, Mars, or anywhere else in space is not feasible. And each of those environments is wildly different from Earth. We’ll need novel approaches to solve all of the problems facing us, and the approaches will have to be sustainable.
This week offers multiple opportunities to get a great look at Mars thanks to several livestreams of Red Planet astronomical events.
The Orion spacecraft had a brief power issue on Sunday (Dec. 4) but did complete its planned engine burn to return home as planned today.

Flying just 80 miles (130 kilometers) off the lunar surface, NASA’s Orion capsule fired its main engine Monday to slingshot around the moon and set a course for splashdown Dec. 11 in the Pacific Ocean to complete the Artemis 1 test flight.
An exclusive interview with "Andor's" VFX producer TJ Falls and sound editor David Acord reveals how the gritty, realistic feel of the series was created.
The venerable Hubble Space Telescope has given us so much during the history of its service (32 years, 7 months, 6 days, and counting!) Even after all these years, the versatile and sophisticated observatory is still pulling its weight alongside more recent addition, like the James Webb Space Telescope (JWST) and other members of NASA’s Great Observatories family. In addition to how it is still conducting observation campaigns, astronomers and astrophysicists are combing through the volumes of data Hubble accumulated over the years to find even more hidden gems.
Ground has finally been broken today at two sites in Africa and Australia that will host the Square Kilometer Array Observatory (SKAO), the largest radio telescope in the world.
A plume of searing hot rock as wide as the continental U.S. is rising up from near the core of Mars and might help explain recent volcanism and earthquakes seen at the Red Planet, scientists say.
An abundance of astro images can make up (a little) for cloudy skies and other things in life that may keep us from observing.
Today at 17:43 CET (16:43 GMT) the European Service Module for Orion fired its main engine at less than 127 km from the Moon's surface to put the Artemis spacecraft on a collision course with Earth.
The team behind NASA's Lucy asteroid mission is resuming work with the spacecraft to fully deploy and latch its second solar array after a recent successful Earth flyby.
