Between September 2003 and January 2004, the Hubble Space Telescope conducted its deepest observations of the cosmos ever. Known as the Hubble Ultra Deep Field, the images produced showed nearly 10,000 galaxies of various ages, sizes, and shapes, including some that existed when the Universe was just 800 million years old. Recently, astronomers were able to revisit this iconic snapshot of the cosmos using two instruments aboard the James Webb Space Telescope (JWST). Their observations set a new record for the longest and deepest observations of an extragalactic field to date.

In the northern hemisphere, we're getting on to enjoying summer time which traditionally includes vacationing. Typically, vacations are a time to pause from work and remember life's possibilities beyond work. Now, perhaps you the vacationer want to rekindle a brief fling you had with science or maybe begin a new science tryst. Ersilia Vaudo's book "The Story of Astrophysics in Five Revolutions" could be just the impetus necessary for such a diversion.

The United States and China aren’t the only powerful, wealthy nations in the world, and they’re certainly not the only nations active in space. For example, there are the Russians, which are…kind of distracted at the moment, so for our purposes there really isn’t much to talk about there.

If you want to get to the moon, you need to spend an enormous amount of resources developing, creating, testing, and deploying a variety of spacecraft and technologies. All you need is money. Lots of money. For decades the only entities with enough green in checking accounts were large governments or multi-national consortia. But nowadays we have some absurdly wealthy, and absurdly motivated, individuals who have stars in their eyes and designs on space missions of their own.

On November 1st, 2024, Project Hyperion - an international, interdisciplinary team of architects, engineers, anthropologists, and urban planners - launched a design competition for crewed interstellar travel. The event was hosted by the Initiative for Interstellar Studies (i4is), a UK-based non-profit organization dedicated to the robotic and human exploration of exoplanets around nearby stars, and eventually settlement. With a prize purse of $10,000, competitors were tasked with producing concepts for a Generation Ship (aka. Worldships) using current technologies and those that could be realized in the near future.

A recent study looked at the feasibility of chasing down 3I/ATLAS.

I don’t think space or lunar tourism is going to be the big draw that transforms the moon into something unrecognizable. Instead, I think it’s going to more about large-scale mining and industrialization that scars the lunar surface. So when it comes to possible industrial hellscapes that the moon might turn into, think less Las Vegas and more…Gary, Indiana. No offense, Gary, but you’re kind of an industrial hellscape.

Simulating extraterrestrial environments on Earth has always been a challenge. Our planet has a pleasant atmosphere, reasonable temperatures, and a moderate amount of gravity, unlike the rest of the solar system. Or maybe that’s just because we think that way because we adapted to how it is here as we evolved here. In either case, the physical environment here makes it difficult for us to set up test environments that can accurately test probes going to other parts of the solar system. Many times, it involves vacuum chambers, air conditioners and heaters pumping hot and cold air into them, and soil simulant - lots and lots of soil simulant. But, according to a new paper from researchers at the University of Wisconsin-Madison, we’ve been neglecting one important aspect of these tests, and it might be the reason Spirit eventually got permanently stuck on Mars - sand is affected by gravity too.

Deep in the heart of our Galaxy lies one of the most chaotic and mysterious regions in space. Now, scientists have created the first detailed map of magnetic fields in this turbulent zone, providing crucial insights into how stars form and evolve in extreme environments.

Science is driven by our desire to understand things. In some cases, where it requires significant effort and investment to develop systems that can understand new things, science benefits from a game plan that the community of researchers focused on a particular niche can rally around, even if they don’t necessarily agree on the details. In astronomy and space science, those game plans typically take the form of Decadal Surveys, produced by the National Academies to define the path forward in a specialization or sub-field.

If you've ever dreamed of exploring space, you know there'll be some serious dangers. One of them is posed by cosmic rays. These high-speed particles slam through anything, including our bodies, damaging DNA and ripping molecules apart. As dangerous as they sound to unprotected spacefarers, they could actually help microscopic life survive hiding under the icy surfaces of places like Europa or Enceladus.

But wait, before you go out to build a moon casino we need to talk about a couple things. One, you really have to figure out how the roulette wheel is going to work in a low gravity environment. Second, we’re going to need you to keep the noise down.

Picture trying to listen to a whispered conversation while standing next to a construction site. That's essentially what radio astronomers face today as thousands of internet satellites flood Earth's orbit, accidentally jamming the faint signals used to unlock the secrets of the universe. A groundbreaking study from Curtin University reveals that the quest for global connectivity is creating an unexpected obstacle to our greatest scientific discoveries, from understanding dark matter to testing Einstein's theories.

As NASA prepares for lunar bases by 2030 and Mars missions by 2039 we face an extraordinary challenge, how do you build a house when shipping materials costs up to $1 million per kilogram? The answer lies in revolutionary construction techniques that could transform how we build right here on Earth.

Imagine one of the crew discovering they're pregnant halfway to Mars, with no chance of returning to Earth for over a year. As space agencies plan multi year missions to the Red Planet, this scenario isn't just science fiction, it’s a genuine possibility that scientists are now seriously studying. A new research paper explores what might happen if humans conceive, carry, and deliver babies during interplanetary travel, revealing both surprising challenges and unexpected opportunities.

How can identifying land on exoplanets help scientists better understand whether an exoplanet could harbor life? This is what a recently submitted study hopes to address as a team of researchers investigated how identifying land on exoplanets could help dispel waterworld false positives, which occur when the data indicates an exoplanet contains deep oceans (approximately 50 Earth oceans), hence the name “waterworld”. This study has the potential to help scientists develop more efficient methods for classifying exoplanets and their compositions, specifically regarding whether they contain life as we know it, or even as we don’t know it.

While Mars may be a dessicated place where water no longer flows, the planet still has glaciers slowly moving across its surface. Previously, it was thought that Martian glaciers were pure ice with a thin cover of rock and dust. But after 20 years of exhaustive research, scientists have concluded that glaciers all over the planet contain more than 80% water ice, meaning they are nearly pure. These findings could alter our understanding of Mars' climate history and have significant implications for future crewed missions dependent on in-situ resource utilization (ISRU).

A new study published in July 2025 tackles one of science's most profound mysteries - how did life first emerge from non living matter on early Earth? Using cutting edge mathematical approaches, researcher Robert G. Endres from Imperial College London has developed a framework that suggests the spontaneous origin of life faces far greater challenges than previously understood.

In astronomy, larger distances are both a blessing and a curse. They can cause issues like longer communication times, which also requires more powerful equipment, and positioning uncertainty that can affect the outcomes of measurements, especially in the outer reaches of the solar system. However, they can also be useful for a specific type of measurement called interferometry, where two systems a far distance apart can provide accurate location measurements to a third system - the same principle that GPS uses. A new paper looks at potentially using the same technique to track deep space probes rather than cars on a freeway and finds that, while it is around the same accuracy level, it is able to provide that same location data for more than double the amount of time.

According to the prevailing theory of how the Moon formed, it all began roughly 4.5 billion years ago when a Mars-sized object (Theia) collided with a primordial Earth. This caused both bodies to become a molten mass that eventually coalesced to form the Earth-Moon System (aka. The Giant Impact Hypothesis. This theory also states that the Moon gradually cooled from the top down, with the crust solidifying and arresting lava flows early in its history. However, recent findings from samples obtained by China's Chiang'e-5 probe indicate that lava existed at shallower depths longer than previously thought.

I’m not exaggerating when I say that our studies of the Moon have unlocked the mysteries of the universe.
