This summer, a team of students and researchers at the University of Alabama in Huntsville successfully conducted three rocket-motor firing tests on a prototype lunar landing pad. The tests showed the prototype’s ability to capture and redirect rocket exhaust through an integrated vent system, marking an important milestone in developing landing infrastructure for future Moon base operations.

When we make our home on other worlds, who will be in charge? Will it be an emperor? A billionaire? A rebel alliance? Or none of the above? Astrobiologist Jacob Haqq Misra runs through the legal and political options.

Astronomers are finding more dusty disks around white dwarf stars, and some of them are home to asteroids. But how these rocky asteroids are turned to dust and form these rings isn't clear. New research shows that the white dwarf's gravity alone can't shred them to dust.

The Vera Rubin Observatory has detected two more of the Milky Ways' dim, hard to see satellites. One is an ultra-faint dwarf galaxy, and one is a globular cluster. Each one is a missing piece of the puzzle in the Milky Way's merger history. By finding more of these satellites, our understanding of galaxy growth, and the role dark matter plays in it, will improve.

Astrophysicists think that black holes grow through a hierarchical merger framework. But the elusive Intermediate Mass Black Holes are the missing link between stellar mass black holes, and the gargantuan supermassive black holes like the one at the center of the Milky Way. The JWST may have found the ancient sources of IMBH heavy seeds: young massive clusters in the high-redshift Universe.

Samples from the asteroid Ryugu, and from carbonaceous chondrites that have crashed on Earth, present an apparent contradiction. Their fine-grained matrices have widely varied compositions of their clay-like minerals. That suggests that there were widely different aqueous environments in the same parent bodies, which seems unlikely. But new research may have solved that contradiction.

The sky in Vincent van Gogh’s The Starry Night (1889) matches, in both observation and shape, the pre-dawn sky over Saint-Rémy around 22 July 1889, when a waning crescent moon, Venus and the Hyades star cluster appeared close together, according to a study published inScientific Reports.

The planet Mars shares many landforms and weather patterns with the Earth, including changing seasons, volcanoes, canyons, dust storms and dust devils, and water ice. But one feature that Earth and Mars share among the eight planets in our solar system are polar ice caps. Both are one of each planet’s striking features, but the major difference is while Earth’s polar ice caps are both comprised of water, Mars’ north polar ice cap is only comprised of water while its southern polar ice cap is carbon dioxide. The reasons for this are determined by altitude, but Mars’ northern polar ice cap is one of the most studied regions primarily due to its water ice composition. But how does the north polar ice cap water ice change with the seasons compared to Earth, and what can this teach scientists about Mars’ climate history?

The dwarf planet Ceres is arguably one of the most overlooked and underappreciated planetary objects in the entire solar system. This could be because while Ceres has the same dwarf planet designation as Pluto, Ceres is largely considered an “asteroid” since it resides the in main asteroid belt. However, along with being the largest object in the main asteroid belt, Ceres’ mass comprises between 25 to 30 percent of all the mass of the entire main asteroid belt. Despite its lack of recognition, Ceres’ interior is layered like most rocky planets, including Pluto, and its surface displays evidence of past water ice activity (also called cryovolcanism) with several “bright spots”, which are highly reflective salt deposits. But what can these salt deposits teach scientists about Ceres’ formation and evolution?

NASA plans to return astronauts to the lunar surface in 2028 for the first time since Apollo 17 in 1972. But the famed agency has no intention of stopping there, as they plan to establish a permanent human presence on the Moon through a slow and meticulous process involving power, resource extraction, and habitat technologies. However, with the soaring use of artificial intelligence (AI) in our everyday lives, how could this emerging technology be used to identify new landing sites for future outposts on the Moon and possibly Mars?

Planetary defense is a growing concern among the scientific community, as efforts have been made to design and implement missions meant to deflect incoming threats to the Earth well in advance. In 2022, NASA intentionally collided the Double Asteroid Redirection test (DART) planetary defense spacecraft into the smaller asteroid of the binary asteroid, Didymos and Dimorphos, with the latter being the smaller one. While the goal was to ascertain if deflecting an asteroid is feasible, how did this influence the geological characteristics of Dimorphos, and what can it teach us about planetary defense missions?

We all know that black holes can collide. It has happened since black holes began to form, early in cosmic time. The result is always a clash that gives off gravitational waves and a giant bang. Since black holes have such strong gravity, it's almost impossible to imagine a way that any force could break one apart. Yet, that's the task that a group of scientists in Europe set for themselves.

Astronomers at Queen’s University Belfast have led an international team studying new solar system bodies near Neptune, helping to unravel the mysteries of our solar system’s evolution.

Ancient Martian meteorites are like time-capsules from the planet's past. They're delivered to us by impacts that launch them into space, where some of them find their way to Earth. One recently discovered meteorite found in the Sahara desert adds weight to the idea that Mars was once warm and wet, and possibly habitable.

In March 2026, NASA's Fermi Gamma-ray Space Telescope detected a GRB with an unusual light signature. Its initial gamma radiation was dim, and the afterglow exhibited unusual, delayed peaks. As it turns out, we were seeing it from a side angle, and the GRB actually packed one billion years of the Sun’s energy output into a thin beam.

Remember the big solar storm back in May 2024? The one that caused auroras as far south as Florida and Mexico? Scientists are still parsing out the impacts that storm had on the local environment, and a new paper published in Geophysical Research Letters by Yoshizumi Miyoshi of Nagoya University and his co-authors shows it might have allowed some nearby electrons to accelerate to relativistic speeds using something called a chorus wave.

Studying the interiors of planets is essential for understanding planetary formation, evolution, and their ability to potentially host life as we know it. To accomplish this, researchers use a combination of Earth as an analog, computer models, meteorites, and data collected from other planetary bodies for studying their interior compositions. As a result, scientists have determined that the elements of magnesium and silicon are the most abundant planetary building blocks. And, under extreme pressures like the interior mantle of our planet, it forms magnesium oxide (MgO) crystals. But how does this same process occur under different pressures and temperatures on other planets like gas giants and larger rocky exoplanets called super-Earths?

Astronomers using the Chandra X-ray Observatory (CXO), the James Webb Space Telescope (JWST) zeroed in on a wispy-looking region of the Carina Nebula and found a ghostly looking cloud seemingly floating in isolation among the other clouds of gas and dust. Just in time for Hallowe'en, although, it turns out that little cloud isn't the soul of departed stars. Instead, it's a region of the nebula has been actively engaged in creating batches of hot, young new stars.

Star formation is a complicated process. It involves metallicity, gas temperature and density, dust grains, and stellar feedback from existing stars. Sometimes, studying all these factors and how they work means studying some of Nature's most beautiful structures, like the Cat's Head nebula in the Carina Nebula.

The latter half of the 20th century saw a major expansion of the Search for Extraterrestrial Intelligence (SETI), accompanied by corresponding advances in Messaging Extraterrestrial Intelligence (METI). A key development was the first interstellar SETI and METI experiments: Project Ozma and the Arecibo Message.
