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.
How can nanosatellites help advance lunar exploration and settlement? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers from Grahaa Space in India investigated the pros, cons, and applications for using nanosatellites on the Moon. This study has the potential to help scientists, engineers, mission planners, and future lunar astronauts develop and test new technologies for advancing lunar exploration, and possibly beyond the Moon.
What are the best methods to explore Valles Marineris on Mars, which is the largest canyon in the solar system? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of researchers investigated how helicopters could be used to explore Valles Marineris, which could offer insights into Mars’ chaotic past. This study has the potential to help scientists and engineers develop new methods for studying Mars’s history and whether the Red Planet once had life as we know it.
For decades, astronomers considered the Perseus cluster to be a stable grouping of galaxies, but more recent observations have shown signs that it experienced a merger in the past. Thanks to an international team of astronomers using the Subaru Telescope at Maunakea, Hawaii, a "Dark Matter bridge" connecting Perseus to a subcluster of galaxies has been discovered.
Space exploration not only allows us to look out into the universe but it also allows us to look back at Earth. ESA’s Biomass satellite will measure the amount of carbon in the world's forests, tracking how the carbon cycle absorbs and releases carbon over the seasonal cycles. It launched this week from the Kourou Spaceport in French Guiana atop a Vega-C rocket and safely reached its intended orbit. It has a synthetic aperture radar that can penetrate forest canopies like an infrared telescope can peer through dark dust clouds.
The James Webb Space Telescope has a number of science goals. One of them is to help understand the evolution of galaxies and their formation within the first billion years after the Big Bang. Astronomers have completed an initial Webb telescope survey that discovered 1,700 galaxy groups. Many of these groups date back to when the Universe was less than 1 billion years old. The survey spans 12 billion years of cosmic history, from these ancient formations to the present day.
Understanding how life started on Earth means understanding the evolution of chemistry in the Solar System. It began in the protoplanetary disk of debris around the Sun and reached a critical point when life appeared on Earth billions of years ago. Close to the Sun, the chain of chemical evidence is broken by the Sun's radiation. But further out in the Solar System, billions of kilometres away, some of that ancient chemistry is preserved.
Space-based solar power (SBSP) has long been the dream of many space enthusiasts and energy economists. However, the reality of economic constraints has long left any practice projects on the ground. There has been plenty of discussion about how to lower the cost of entry to build the kind of space-based solar power satellite described by John Mankins in his books and articles. However, even with the advent of lower costs to orbit thanks to reusable rockets, the economic case for SBSP is still not great simply due to the sheer amount of mass required to get into orbit. Unless we get that mass from somewhere else, with a smaller gravity well. Astrostrom, which means something like "Star current" in German, is an organization based in Switzerland that hopes to make space-based solar power a reality.
Astronomy has entered the age of gravitational waves. While there are plenty of differences between gravitational wave astronomy and typical waves of the electromagnetic spectrum, they share one similar feature: frequency. While we have detectors for a wide range of electromagnetic frequencies, gravitational wave detectors only focus on a narrow band of relatively low-frequency signals. That will change with the upgrade of the GEO600 gravitational wave detector located at the Max Planck Institute for Gravitational Physics.
