Artemis 1 Orion spacecraft captures moon craters in stunning flyby footage (video)
The NASA Orion spacecraft captured incredible footage of two big moon craters during a close flyby on Monday (Dec. 5). All you need to see them yourself is a small telescope.
Mars at Opposition 2022: The Full Moon Occults Mars Wednesday Night
A rare event transpires Wednesday night, as the Full Moon occults Mars near opposition.
NASA's Artemis 1 Orion snaps gorgeous moon views as it sails over Apollo landing sites (video)
The Orion spacecraft flew over the landing sites where Apollo astronauts roamed in the 1960s and 1970s. The Artemis program, however, will find different rocks.
Coming soon: MTG The Next Generation
Video: 00:00:48
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.
How much of the universe is dark matter?
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.
Artemis 1 Orion spacecraft on track for return to Earth after moon flyby
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.
Status Update: Artemis 1's SmallSat Missions
Some of the small missions deployed from Artemis 1 will go on to do great things, while others remain silent.
GPS: Everything you need to know about the space-based technology keeping us on track
We GPS all the time but how does it work and why was it invented? Here we explore this vital space-based technology.
Artemis 1 Orion spacecraft aced its test flight but still hasn't tested life support
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.
Construction Begins on the Square Kilometer Array
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).
SOFIA Fails to Find Phosphine in the Atmosphere of Venus, But the Debate Continues
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.
Hubble Spots Two Open Clusters. One is Also an Emission Nebula
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.
Ground Telescopes can Adapt to Satellite Megaconstellations if They get Accurate Telemetry Data
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.
Want to Colonize Space? Unleash the Power of Microbes
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.
See Mars at opposition pass behind the moon this week for free online
This week offers multiple opportunities to get a great look at Mars thanks to several livestreams of Red Planet astronomical events.
Artemis 1 Orion spacecraft suffered power blip hours before its close lunar flyby
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.
Artemis 1 capsule beams back spectacular farewell views of the moon

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.
'Andor' sound and VFX wizards on bringing a grittier 'Star Wars' to life (exclusive)
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.
By Looking Back Through Hubble Data, Astronomers Have Identified six Massive Stars Before They Exploded as Core-Collapse Supernovae
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.
Construction begins on world's largest radio telescope after decades of preparations
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.
