The launch tower supporting the first three Artemis moon missions was back on the move for the first time Wednesday after more than half a year of repairs and upgrades.
An observing campaign involving New Horizons, the Hubble Space Telescope and perhaps even you is designed to better understand how heat flows through the atmospheres of two ice giants.
SpaceX has submitted to the FAA its final report about the debut launch of its Starship vehicle, which ended with a bang four minutes after liftoff.
The Curiosity Mars rover recently aced its toughest Red Planet climb yet: a sharp 23-degree slope covered slippery sand and wheel-size rocks.
The Sun dominates the Solar System in almost every way imaginable, yet much of its inner workings have been hidden from humanity. Over the centuries, and especially in the last few decades, technological advancements allowed us to ignore our mothers’ exhortations and stare at the Sun for as long as we want. We’ve learned a lot from all those observations.
Just how dark is the night sky?
The first Artemis mission to make use of NASA's moon-orbiting Gateway will be Artemis 4 in 2028, agency officials confirmed this month.
One of the main objectives of the James Webb Space Telescope (JWST) is to use its powerful optics and advanced instruments to observe the earliest galaxies in the Universe. These galaxies formed about 1 billion years after the Big Bang, coinciding with the end of what is known as the “Cosmic Dark Ages.” This epoch is inaccessible for conventional optical telescopes because the only sources of photons were largely associated with the relic radiation of the Big Bang – visible today as the Cosmic Microwave Background (CMB) – or were the result of the reionization of neutral hydrogen (visible today the 21 cm line).
India is gearing up for its first-ever mission to study the sun, Aditya-L1, which is expected to launch in early September.
The United States Space Force has activated its first and only unit dedicated to targeting other nations' satellites and the ground stations that support them.
Luna-25, Russia's first moon mission in nearly half a century, has reached lunar orbit, the nation's space agency Roscosmos reported today (Aug. 16).
Astrophotographer Miguel Claro captured a stunning time-lapse video of solar flares dancing across the sun from the Dark Sky Alqueva site in Portugal.
Europe's most active volcano, Italy's Mount Etna, erupted on Sunday (Aug. 13) after weeks of puffing out odd smoke rings. Here is how it looked from space.
While there are hints that dark energy may be 'phantom,' its true nature remains frustratingly elusive, a new study reports.
NASA brought a small group of reporters to its Kennedy Space Center to see three spacecraft, including the Orion for Artemis 2. A Canadian reporter was there to see it.
There are two solar eclipses every year — so why are they so rare?
SpaceX plans to launch two Starlink missions less than seven hours apart late Wednesday (Aug. 16) and early Thursday (Aug. 17), and you can watch them live.
NASA is emphasizing a seamless transition to future private space stations in low-Earth orbit, but officials say the shift will not be easy.

While many people are living through a sweltering summer, it’s the depths of winter in Antarctica. Usually, this means there’s a lot of sea ice around the continent. Yet, this year, it’s the lowest it’s ever been. What’s happening?
From June 18th to 22nd, the Penn State Extraterrestrial Intelligence Center (PSETI) held the second annual Penn State SETI Symposium. The event saw experts from many fields and backgrounds gathering to discuss the enduring questions about SETI, the technical challenges of looking for technosignatures, its ethical and moral dimensions, and what some of the latest experiments have revealed. Some very interesting presentations examined what will be possible in the near future and the likelihood that we will find evidence of extraterrestrial intelligence.
