In the latest chapter of “The Mystery of the Lunar Swirls,” planetary scientists have a new theory to explain these odd markings on the Moon’s surface. It invokes underground magmas and strange magnetic anomalies.

Robotic companions are a mainstay of sci-fi series everywhere. From R2D2 to Johnny 5, these characters typically have a supporting role in the story and are helpful to their human companions. But what if they were integral to the humans in the story? So much so that they couldn’t live without their robotic compatriots? That’s the idea behind Biobot, which was given a NIAC grant in 2018 – why not use a robotic companion to carry supporting equipment on human extravehicular activities (EVAs) on other planets?

Universe Today has had the recent privilege of investigating a multitude of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, cosmochemistry, meteorites, radio astronomy, extremophiles, organic chemistry, black holes, cryovolcanism, planetary protection, dark matter, supernovae, and neutron stars, and how they both individually and collectively contribute to our greater understanding of our place in the universe.
Here, Universe Today discusses the growing field of exomoons with Dr. David Kipping, who is an assistant professor in the Astronomy Department at Columbia University, along with his PhD students, Benjamin Cassese and Daniel Yahalomi, regarding the importance of studying exomoons, the benefits and challenges, potential exomoon candidates, how exomoons can teach us about finding life beyond Earth, and advice for upcoming students who wish to pursue studying exomoons. Therefore, what is the importance of studying exomoons?

Both the Milky Way and a galaxy known as M87 have supermassive black holes at their core. These are the two largest black holes we know about and the Event Horizon Telescope has just captured stunning images of their event horizons. A new paper looks at what we might expect from a next generation EHT and highlights twelve targets that should be top of the list.

Over the last several months, Universe Today has explored a plethora of scientific disciplines, including impact craters, planetary surfaces, exoplanets, astrobiology, solar physics, comets, planetary atmospheres, planetary geophysics, cosmochemistry, meteorites, radio astronomy, extremophiles, organic chemistry, black holes, cryovolcanism, planetary protection, dark matter, and supernovae, and how each of these unique disciplines continue to teach is about the cosmos and our place throughout its vastness.
Here, Universe Today discusses the field of neutron stars with Dr. Stuart Shapiro, who is a Professor of Physics and Astronomy and NCSA Senior Research Scientist at the University of Illinois at Urbana-Champaign, regarding the importance of studying neutron stars, the benefits and challenges, the most intriguing aspect about neutron stars he’s studied throughout his career, and any advice he can offer upcoming students who wish to pursue studying neutron stars. Therefore, what is the importance of studying neutron stars?

How can young galaxies in the early Universe have ancient stars? That’s the question a team of astronomers set out to answer using JWST as a probe. They first spotted the massive objects in 2022 and are still working to explain what these things are.

NASA’s Space Communications and Navigation programme (SCaN) has demonstrated the first two way end-to-end laser relay system, deployed through an innovative network. To test SCaN, they sent data to the International Space Station at the impressive speed of 1.2 gigabits per second. Using bandwidth that would normally be reserved for more important communications, the chosen message for the test was a set of adorable images and videos featuring the pets of NASA astronauts and staffers.

The Gemini Observatory has unveiled a striking new image that shows star formation within the irregular galaxy NGC 4449. This galaxy is categorised as a “Magellanic-type” galaxy due to its similarities with the Magellanic Clouds, although it is smaller in size. Surrounding NGC 4449 is a halo of smaller dwarf galaxies, two of which are currently merging with it. This merger is causing clouds of gas to collide, fuelling the surge in star formation observed in NGC 4449.

When astronauts land on Mars someday, they might have to live in lava caves or lava tubes to survive the harsh radiation that rains down on the Martian surface every second. But which caves could offer them the best chance of survival? This is what a recent study presented at the 55th Lunar and Planetary Science Conference hopes to address as Dr. Anatoliy P. Vidmachenko from the National University of Life and Environmental Sciences of Ukraine investigated where, how, and why lava tubes and lava caves could aid future Mars astronauts regarding their survival. This study holds the potential to help scientists and engineers help mitigate risks for future Mars astronauts and what steps that need to be taken to make that a reality.

To get to the Moon, NASA is building a Lunar Gateway in orbit to facilitate easier access to the Moon. With construction beginning in 2028 as part of Artemis IV there will be an ongoing programme of enhancements and additions. NASA has now released a fabulous new 3D animation of the Lunar Gateway to showcase what the final Gateway will look like. It includes modules from partner nations and an Orion lunar landers dock to carry astronauts.
