- by Stuart ClarkOn 30 September the Red Planet officially begins Mars Year 39. Which is quite an achievement for a world that is actually more than 4.5 billion years old.
- by Stuart ClarkAnother piece of evidence suggests that this visitor formed in the bitterly cold outer reaches of a distant planetary system.
- by Stuart ClarkNASA’s Nancy Grace Roman Space Telescope has begun its journey into space, starting a mission that will survey the Universe on an unprecedented scale in search of clues to dark energy, dark matter and worlds beyond our Solar System.
- by Stuart ClarkFaint, low-mass stars could be hiding much of the mass in distant galaxies, making the surprisingly large galaxies discovered by JWST in the early Universe even harder to explain.
- by Emily Baldwin-FiebrichOn the evening of 12 August 2026, the Moon will pass between Earth and the Sun, producing a striking solar eclipse. Find out how, when and where to observe it safely.
- by Stuart ClarkToday’s impact of a spent Falcon 9 rocket stage on the Moon may sound dramatic, but it is neither the first human-made object to strike our natural satellite nor the largest.

Astronomy
- by Elisa NeckarIn early September 1882, a comet was sighted from the Cape of Good Hope in South Africa. The comet brightened over the following weeks, reaching a magnitude of -2 on the 15th; at perihelion two days later, it was bright enough to be visible during the day. But at the time, David Gill, the directorContinue […]

- by Liz KruesiThe earliest test of Albert Einstein’s general theory of relativity took place just four years after he published it. During the May 29, 1919, total solar eclipse, British astronomer Sir Arthur Eddington and colleagues studied the theory by measuring how the Sun distorts light from background stars. According to general relativity, any object with massContinue […]
- by Jake ParksThe phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moon’s orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue […]
- by Mark ZastrowKatelyn Beecroft from London, Ontario, Canada On the morning of Oct. 6, 2026, the waning crescent Moon — then about 20 percent lit — occulted Jupiter as seen from much of eastern North America. This imager, tracking by hand with an 8-inch Dobsonian reflector, stacked the sharpest frames from video shot with a ZWO ASI224MCContinue […]

Universe Today
- The decades old idea that our solar system’s Oort Cloud is continually perturbed by a heretofore undetected low mass Red Dwarf star remains the best explanation for periodicities found in Earth’s impact record. Or so says a well known physicist who has long championed this idea.
- Ultra-Diffuse Galaxies are strange because they're as large as the Milky Way, but have far fewer stars. It's as if they're puffed up for some reason. Determining what's going on with them could help confirm the Lambda-CDM model. A new proposed instrument for the Extremely Large Telescope could give astronomers their best look yet at […]
- NASA's ESCAPADE mission features a pair of identical spacecraft on their way to Mars. They launched outside of the normal launch window, so they'll perform powered slingshot maneuvers to boost their speed. Once there, they'll "fly" in formation and study how the solar wind interacts with what remains of Mars ancient magnetosphere.
- We typically think of the Moon as a static, floating object that has remained the same for basically its entire lifetime, with an occasional asteroid impact serving as an exception. That understanding is grounded in physics – the Moon should have cooled rapidly after forming when a huge protoplanet hit the early Earth around 4.5 […]
- Flashback to 1977. Jimmy Carter was U.S. president, Star Wars was a box office hit, and the two Voyager spacecraft departed on an historic Grand Tour of the solar system. Now, teams at NASA’s Jet Propulsion Laboratory are working to keep the missions active, as they push the boundaries of interstellar space beyond the solar […]
- In a pinch, we could use a stand-off nuclear blast to redirect a dangerous asteroid on short notice. There's no atmospheric shock wave in space, but the x-ray pulse could still deflect the space rock. But asteroids aren't round and uniform, so their weird shapes make it difficult.
NASA
- by Jessica TaveauNASA announced a suite of awards and mission updates on Saturday to expand the agency’s Moon Base exploration, science, and infrastructure capabilities. The investments will advance commercial robotic deliveries, a nuclear-powered rover named PROMISE, launch and orbital transfer services, and surface infrastructure as the agency works with American industry to establish a sustained presence on […]

ESA
- As we prepare to return to the Moon, Europe’s leading geology training for astronauts PANGAEA celebrates its 10th anniversary turning extraordinary places on Earth into classrooms for space exploration.
- Before the Rosalind Franklin rover can explore Mars, it must first get off its lander.
- For eight days, a Mars rover prototype travelled 220 metres across a barren landscape, following commands from a science team some 1200 kilometres away.
- When an astronaut from the European Space Agency (ESA) returns from space, the mission is far from over.
- On 9 October, astronauts on the International Space Station begin supporting the final decommissioning of ESA's Fluid Science Laboratory (FSL), one of the longest-serving scientific facilities inside Europe's Columbus laboratory.
- As part of the preparation for the end of utilisation of the International Space Station (ISS), the European Space Agency (ESA) awarded a contract to two European industrial consortia to conduct preliminary studies assessing the feasibility to develop a future European-led orbital outpost. These studies are part of the options currently explored by ESA for […]
