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.

NASA's mission to Jupiter has revealed new findings about the giant planet and its volcanic moon.

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.

President Donald Trump’s pick to lead NASA in his second term is one step closer to becoming the agency’s 15th administrator.

Data from Europe's Gaia spacecraft have revealed that a cluster of 1,000 stars is breaking up much faster than is normal, stumping astronomers.

This spectrograph map, generated from data collected by NASA's New Horizons probe, depicts the relatively uniform brightness of the ultraviolet "Lyman-alpha" background surrounding our Sun and its area of influence.

NASA is asking private industry and academia for ideas for new rescue services for its astronauts on Earth in the event of emergencies.

We know that our Milky Way galaxy hosts a supermassive black hole (SMBH) in its center. Astronomers think most spiral galaxies do, and that SMBHs coexist and co-evolve with their host galaxies. However, they haven't been able to find them in all spirals. M83, the Southern Pinwheel Galaxy, has always been puzzling because scientists haven't seen any evidence of an SMBH in its center. The JWST may have finally found some.

Astronomers have captured the sharpest, most detailed images yet of young solar systems where planets are just beginning to take shape.

Earthlings take on a lunar revolution in this exhausting-but-ambitious sci-fi spectacle

Amateur astrophotographer Joel Martin captured this stunning view of Bode's galaxy in February this year during a stargazing festival in Death Valley, California.

It’s one straight out of the history books. After over 50 years in space, the late Soviet Union’s Kosmos-482 mission is set to reenter the Earth’s atmosphere, early next month. Stranded in Earth orbit, there are just a few weeks remaining to see this enigmatic relic of a bygone era.

Having explored the 'third rock from the sun,' John Lithgow is heading for its moon. The actor is set to star in the new podcast "BUZZ" about the life of one of the first humans to land on the moon.
