How can walking robots deliver more efficient in-situ robotic exploration on the Moon compared to other types of robots? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from the University of Southern California (USC) discussed the benefits of using legged robots for lunar exploration regarding gait speed (walking speed). This study has the potential to help engineers, scientists, mission planners, and astronauts develop novel robotic designs to conduct more efficient science and mission objectives on future Moon surface missions.

Earth has a number of companions in space; of course the Moon is the most well known but there are a host of smaller objects that visit us, complete a few orbits then head off again. A team of astronomers have detected four objects like this and have performed spectroscopic analyses on them. They found that their surface composition is similar to eh Moon suggesting that it’s a major source of these temporary satellites instead of the asteroid belt.

The Orion Nebula is a fabulous example of a vast cloud of electrically charged gas which is emitting bright radiation. If the atoms in the gas are cool enough though, they can form giant molecular clouds that obscure light, these are known as dark nebula. A team of astronomers have now found an enormous cloud of molecular hydrogen in our own cosmic backyard just 300 light years away. The cloud contains 3,400 times the mass of the Sun and if we could see it, it would stretch nearly 40 times the width of the Moon across the sky.

How do robots feel in space? This is both a practical and possibly an existential question. Still, today, we'll focus on the practical side by looking at a review paper from Hadi Jahanshahi and Zheng Zhu of York University in Canada that discusses different tactile sensor types and their advantages and disadvantages for use in space.

Ion drives are renowned for their efficiency. They're extremely efficient compared to chemical rockets, so they're preferred for deep space missions where propellant supplies are critical. New research shows how they could run on simple water, making them even more efficient.

It's nearly impossible to overstate the effect supermassive black holes have on their host galaxies. When actively accreting matter, they release colossal amounts of energy as winds, jets, and radiation that shape their surroundings. But stellar mass black holes also shape their surroundings with energetic jets.

Nothing wows new observers like seeing Saturn for the first time. I always check out the ringed planet if it's visible, and telescopes down the line at any star party will invariably be pointed Saturn-ward to a chorus of ‘oh’s’ and ‘ah’s’…. but 2025 gives you another reason to gaze at Saturn, as its largest moon Titan completes a series of rare shadow transits.

NASA's Psyche mission launched in 2023 and has now successfully demonstrated that laser technology can transmit high-bandwidth data across millions of kilometres in space, making it promising for communications from Mars. However, researchers simulating Martian conditions found that while this optical communication works well under normal circumstances, performance degrades during dustier periods and fails completely during global dust storms.

What kind of spacecraft can be used to explore and study the subsurface lunar environment? This is what a recent study presented at the 56th Lunar and Planetary Science Conference (LPSC) hopes to address as an international team of researchers discussed the benefits of a mission concept called LunarLeaper, which will be designed to traverse and analyze the various aspects of the lunar subsurface environment, including moon pits and lava tubes.

Since the invention of the telescope, astronomers have been hunting for objects in our Solar System in particular and more recently, for the theorised 9th planet. Observations of Kuiper Belt objects suggest a large object might be lurking in the depths of the Solar System but to date, it hasn’t been directly observed. A team of researchers have analysed infrared sky surveys and found 13 objects that matched the estimated flux and motion of Planet Nine! Further analysis ruled out 12 leaving a single object. Is this Planet Nine?

A few years ago, astronomers discovered an exoplanet orbiting the white dwarf 1856+534 b. Now they've used the mighty JWST to do follow-up observations and made some exciting discoveries. It's definitely a planet and not a brown dwarf, with a temperature of 186 K (-87°C/-125°F) and about 6 times the mass of Jupiter. This makes it the coldest exoplanet ever detected, and it's orbiting in the "forbidden zone," which should have been engulfed during the red giant phase.

Magnetars are among the rarest - and weirdest - denizens of the galactic zoo. They have powerful magnetic fields and may be the source of fast radio bursts (FRBs). A team of astronomers led by European Space Agency researcher Ashley Chrimes recently used the Hubble Space Telescope to track one of these monsters called SGR 0501+4516 (SGR0501, for short, and SGR stands for Soft Gamma Repeater). It's whipping through the Milky Way at a rate that could be as high as 65 kilometers per second. The big challenge was to find its birthplace and figure out its origin.

Since the discovery of the first exoplanet in 1992 astronomers have now found over 5,000 alien worlds around other stars. With the discoveries of exoplanets came an entirely new classification of worlds known as the super-Earth; terrestrial planets more massive than Earth but smaller than Neptune. Sadly we don’t have any such planets in our Solar System but a new report suggests planets like this are surprisingly common with at least as many as there are Neptune sized planets.

In a recent paper, a team of engineers from Purdue University describes how sandbox video games that offer players a high degree of freedom and creativity, like the popular Kerbal Space Program (KSP), could be used by space agencies to assist the early-mission development process.

The White House Releases its 2026 Budget Request for NASA. Cuts to SLS, Gateway and Orion

Has your dinner time conversations been dragging a bit of late? Feel like raising its knowledge level to a bit higher than the usual synopsis of the most recent reality TV show? Then take the challenge presented by Sean Carroll in his book "The Biggest Ideas in the Universe – Space, Time and Motion". Using this, your conversation might soon be sparkling with grand thoughts about modern physics, time travel, going faster than light and the curvature of the universe.

The Juno spacecraft circling in Jovian space is the planetary science gift that just keeps on giving. Although it's spending a lot of time in the strong (and damaging) Jovian radiation belts, the spacecraft's instruments are hanging in there quite well. In the process, they're peering into Jupiter's cloud tops and looking beneath the surface of the volcanic moon Io.

As young stars form, they exert a powerful influence on their surroundings and create complex interactions between them and their environments. As they gobble up gas and dust, they generate a rotating disk of material. This protoplanetary disk is where planets form, and new research shows that stars can feed too quickly and end up regurgitating material back into the disk.

A team of researchers led by the Los Alamos National Laboratory examined the possibility that the jets coming from collapsing stars could be responsible for creating the heaviest elements in the Universe.

We tend to think of Extraterrestrial Intelligences (ETIs)—if they exist—as civilizations that have overcome the problems that still plague us. They're advanced, peaceful, disease-free technological societies that enjoy absolute political stability as they accomplish feats of impeccable engineering. Can that really be true in a Universe where entropy sets the stage upon which events unfold?

What methods can be employed to send a spacecraft to Uranus despite the former’s immense distance from Earth? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists investigated ways to cut the travel time to the second most distant planet from the Sun. This study has the potential to help scientists, engineers, and mission planners develop low-cost and novel techniques for deep space travel while conducting cutting-edge science.
