You know, if you take away the lack of air and water, the weaker Sun, the lower gravity, and the toxic soil, Mars isn’t all that bad of a place to live. And there are certainly worse places to live, like, I don’t know, Ohio (I’m allowed to say that because I grew up there). But there’s been a big push in the past two decades to not just go to Mars and visit, like we did with the Moon fifty years ago, but to stay there. Put down roots. Establish ourselves. Build a colony or a settlement.

78 million years ago, a 1.6 km asteroid slammed into what is now Finland, creating a crater 23 km (14 mi) wide and 750 km deep. The catastrophic impact created a fractured hydrothermal system in the shattered bedrock under the crater. There's evidence from other impact structures that in the aftermath of a collision, life colonized the shattered rock and heated water that flowed through it. But determining when the colonization happened is challenging.

When considering the unnamed major features of all the moons, asteroids, and comets in our solar system there are still a lot of places out there that need proper names. That means the International Astronomical Union (IAU), the non-governmental body responsible for naming astronomical objects, has its work cut out for them. Recently they tackled a relatively easy challenge by approving a series of names on the asteroid Donaldjohnson, the first and only target of NASA’s Lucy mission in the main asteroid belt. With those names come a whole new way to talk about one of the asteroids that humanity has studied most closely thus far.

When the ESA launched the Gaia spacecraft in 2013, it didn't generate the same fanfare as the launch of other missions like the JWST, or first light from telescopes like the Vera Rubin Observatory. That's largely because Gaia doesn't capture gorgeous images of celestial objects like other telescopes. Instead, Gaia was an astrometry mission.

Whenever astronomers detect something new moving through our region of space, like an interstellar object or an unusual asteroid, somebody somewhere claims it could be an alien interstellar space probe. It's like one of those laws about human behaviour—Godwin's Law for example—that should probably have its own name.

We don't realize it, but Earth is subjected to a constant cosmic rain of material. The vast majority of it is tiny micrometeors that burn up in the atmosphere, up to 100 tons per day by some estimates. But sometimes, much larger objects strike Earth. The most notable is probably the Chicxulub impactor that wiped out the dinosaurs and left a massive crater, now buried.

There are plenty of theories about what dark matter is and how it might be gravitationally affecting the universe. However, proving those theories out is hard since it hardly ever interacts with anything, especially on “small” scales like galaxies. So when a research team claims to have found evidence for dark matter in our own galaxy, it's worth taking a look at how. A new paper from Dr. Surkanya Chakrabati and her lab at the University of Alabama at Huntsville (UAH) does just that. They found evidence for a dark matter “sub-halo” in the galactic neighborhood, by looking at signals from binary pulsars.

A new comet approaching from sunward could make a fine dusk appearance in October.

Three data releases from the recently retired Gaia spacecraft show that far-flung parts of the Milky Way are connected by families of stars born in clusters. Some continue to travel the galaxy together, while others appear wildly dispersed, sometimes as chains of related stars. One cluster is even trying to escape the Milky Way. The Gaia data show that open clusters (in particular) and the star formation regions from which they spring are interconnected across the Galaxy, populating the Milky Way in ways astronomers are just now beginning to understand.

The grinning Moon slides by Regulus and Venus later this week, in a complex event.

One possibility to explain the constants of nature is that there’s more than one universe. That we live in a multiverse, with each different universe “sampling” different values of the constants. There are a few extremely hypothetical ideas in physics that can lead to the multiverse. One is through the concept of eternal inflation, where the very early universe never ended its period of rapid expansion, and that different portions of the overall multiverse pinched off, so to speak, to create their own bubble universes.

Blue Origin is committed to making a permanent human presence in space a reality. To this end, they have developed the New Shepard and New Glenn rockets to send payloads to orbit, and aim to create super-heavy launch vehicles to reach the Moon (New Armstrong and Blue Origin) and beyond. Another focus has been on developing systems that will enable In-Situ Resource Utilization (ISRU) in extraterrestrial environments, which is essential for making space sustainable. This includes their Blue Alchemist ISRU system, which recently completed its Critical Design Review (CDR).

What are the constants of nature? What do they do? What do they tell us…and what do they not tell us?

Scientists at The University of Texas at Austin have discovered that volcanic activity on Mars between 3 and 4 billion years ago likely released unusual forms of sulphur gases that could have trapped heat and maintained liquid water on the planet's surface. This finding, published in Science Advances, offers a fresh perspective on how Mars might have supported early life.

On July 1st, 2025, astronomers at NASA's Asteroid Terrestrial-impact Last Alert System (ALERT) detected the third interstellar object (ISO) to enter our Solar System - 3I/ATLAS. Shortly thereafter, an international team led by researchers from Michigan State University (MSU) published the first scientific paper detailing the early scientific findings on this ISO. Hundreds of hours of observations have since been dedicated to measuring the astrometry, photometry, rotation period, and spectroscopy of this object to determine its trajectory, composition, and where it came from.

Deep in space, an ancient brown dwarf nicknamed "The Accident" has revealed the first-ever detection of a molecule that scientists have been searching for in planetary atmospheres for decades. This discovery not only explains why silicon remains hidden in Jupiter and Saturn's atmospheres, but also opens a window into how the chemistry of our universe has evolved over billions of years, showing us that sometimes the most unexpected finds yield the greatest scientific breakthroughs.

Science is a story of coming up with theories then doing our best to disprove them. That is especially true for theories on a grand, cosmological scale, though disproving them can be particularly hard. One of the most famous examples of a hard to disprove theory is that of dark energy and dark matter. In large parts of space we see unequivocal evidence that something is messing with general relativity. But down at the scale of our own solar system, there’s no evidence of it whatsoever, at least as far as we can see. A new paper from Slava Turyshev, a physicist at NASA’s Jet Propulsion Laboratory, discusses a way scientists might be able to deal with this discrepancy - by being very, very selective with the way we test for evidence of dark matter and energy in our solar system.

Comet 3I/ATLAS's appearance in the inner Solar System in July 2025 triggered a wave of interest. Not only in the comet itself, but in interstellar objects (ISO) in general. So far we only know of three ISOs, and it's only natural to wonder about their origins, and how common they are. But scientists, being naturally curious, have other questions, too. What would happen if an ISO was captured by a young solar system?

The period known as "Cosmic Noon," which took place roughly 2 to 3 billion years after the Big Bang, was characterized by the rapid formation of new stars and planetary systems. Naturally, objects dated to this period are coveted by scientists hoping to learn more about the processes that led to the formation of planets and the emergence of life itself. This includes asteroids and comets, which are known to be composed of material leftover from the formation of entire star systems and their planets. And with the detection of three interstellar objects (ISOs) in the Solar System since 2017, there could be multiple opportunities to do so.

Ten years ago, we heard the universe whisper for the first time. On September 14, 2015, the Laser Interferometer Gravitational wave Observatory (LIGO) detected ripples in space-time. The signal came from the gravitational waves that had traveled 1.3 billion years to reach Earth, carrying the story of two colliding black holes. This historic moment, predicted by Einstein a century earlier, opened an entirely new way of experiencing the universe.

Different parts of Mars have different advantages and disadvantages when it comes to their available resources, just like Earth. The polar caps are likely the most valuable in terms of their water content, which will be critical to any early stage crewed mission to the Red Planet. But to really unlock the fully potential of Mars, geologists think we’ll need to look to the volcanoes, where there is likely to be easily accessible valuable materials like nickel, titanium, and chromium, that were placed there when the volcanoes were active. Reaching those deposits on the side of some of the largest mountains in the solar system safely is a challenge, and one that is tackled in a new paper by Divij Gupta and Arkajit Aich, where they look at the necessary requirements to set up an effective mining operation on the slopes of Olympus and Elysium Mons.
