A new Hubble Image Reveals a Shredded Star in a Nearby Galaxy
The Hubble Space Telescope, to which we owe our current estimates for the age of the universe and the first detection of organic matter on an exoplanet, is very much doing science and still alive. It’s latest masterpiece remixes an old hit – apparently a growing trend in science as well as music.
Listen to the Artemis 1 Orion capsule phone home from deep space
Orion broadcasts its data signal toward Earth, where it is received by three dishes that make up NASA's Deep Space Network, but amateur observers can also tune in throughout the mission.
Evidence of a Megatsunami on Mars
Things were pretty wet back on Mars about three and a half billion years ago. You wouldn’t know that by looking at the planet today. But, would you believe a megatsunami happened there? It turns out that not one, but two of these rogue waves happened there some 3.4 billion years ago.
What time will the moon eclipse Mars on Dec. 7?
A bright Mars at opposition will disappear behind the moon on Wednesday (Dec. 7), but exactly when you should look up depends on where you are.
Solar cycle peak reduces cosmic rays around Mars, Venus and Earth
Measurements taken at Earth's neighbors, Mars and Venus, show the battle between high-energy cosmic rays from beyond the solar system and the influence of the sun in the inner solar system.
Mauna Loa's continuing eruption is spectacular in satellite views
Satellites keep watching as the Mauna Loa volcano on Hawaii's Big Island continues spewing geysers of boiling lava and plumes of volcanic ash over a week after it woke up from a 38-year sleep.
NASA's revolutionary Moonboard launched Artemis 1 coverage to new heights
NASA's media team incorporated an advanced 'Moonboard' touchscreen to help viewers understand the launch of the SLS rocket and Orion's journey around the moon.
Not Just Stars. Gaia Mapped a Diverse and Shifting Universe of Variable Objects
We’ve reported on Gaia’s incredible data-collection abilities in the past. Recently, it released DR3, its latest data set, with over 1.8 billion objects in it. That’s a lot of data to sift through, and one of the most effective ways to do so is through machine learning. A group of researchers did just that by using a supervised learning algorithm to classify a particular type of object found in the data set. The result is one of the world’s most comprehensive catalogs of the type of astronomical object known as variables.
Mars helicopter Ingenuity soars higher than ever on 35th Red Planet flight
NASA's Mars Ingenuity helicopter set a new altitude record on Sunday (Dec. 3), getting 46 feet (14 meters) up on its 35th Red Planet flight.
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.
