Almost every large galaxy has a supermassive black hole churning away at its core. In most cases, these black holes spin in concert with their galaxy, like the central hub of a cosmic wagon wheel. But on December 18, 2024, NASA researchers announced they had discovered a galaxy whose black hole appears to have been turned on its side, spinning out of alignment with its host galaxy.

Through the Artemis Program, NASA will send the first astronauts to the Moon since the Apollo Era before 2030. They will be joined by multiple space agencies, like the ESA and China, who plan to send astronauts (and “taikonauts”) there for the first time. Beyond this, all plan to build permanent habitats in the South Pole-Aitken Basin and the necessary infrastructure that will lead to a permanent human presence. This presents many challenges, the most notable being those arising from the nature of the lunar environment.
Aside from the extremes in temperature, a 14-day diurnal cycle, and the airless environment, there’s the issue of lunar regolith (aka moondust). In addition to being coarse and jagged, lunar regolith sticks to everything because it is electrostatically charged. Because of how this dust plays havoc with astronaut health, equipment, and machinery, NASA is developing technologies to mitigate dust buildup. Seven of these experiments will be tested during a flight test using a Blue Origin New Shepard rocket to evaluate their ability to mitigate lunar dust.

New research suggests that our best hopes for finding existing life on Mars isn’t on the surface, but buried deep within the crust.

Entanglement is perhaps one of the most confusing aspects of quantum mechanics. On its surface, entanglement allows particles to communicate over vast distances instantly, apparently violating the speed of light. But while entangled particles are connected, they don’t necessarily share information between them.

Neutrinos are tricky little blighters that are hard to observe. The IceCube Neutrino Observatory in Antarctica was built to detect neutrinos from space. It is one of the most sensitive instruments built with the hope it might help uncover evidence for dark matter. Any dark matter trapped inside Earth, would release neutrinos that IceCube could detect. To date, and with 10 years of searching, it seems no excess neutrinos coming from Earth have been found!

A team of astronomers have detected a surprisingly fast and bright burst of energy from a galaxy 500 million light years away. The burst of radiation peaked in brightness just after 4 day and then faded quickly. The team identified the burst, which was using the Catalina Real-Time Transient Survey with supporting observations from the Gran Telescopio Canarias, as the result of a small black hole consuming a star. The discovery provides an exciting insight into stellar evolution and a rare cosmic phenomenon.

Meet the brown dwarf: bigger than a planet, and smaller than a star. A category of its own, it’s one of the strangest objects in the universe.

In 1971, the Soviet Mars 3 lander became the first spacecraft to land on Mars, though it only lasted a couple of minutes before failing. More than 50 years later, it’s still there at Terra Sirenum. The HiRISE camera NASA’s Mars Reconnaissance Orbiter may have imaged some of its hardware, inadvertently taking part in what could be an effort to document our Martian artifacts.
Is it time to start cataloguing and even preserving these artifacts so we can preserve our history?
Some anthropologists think so.

In 2019, astronomers observed an unusual gravitational chirp. Known as GW190521, it was the last scream of gravitational waves as a black hole of 66 solar masses merged with a black hole of 85 solar masses to become a 142 solar mass black hole. The data were consistent with all the other black hole mergers we’ve observed. There was just one problem: an 85 solar mass black hole shouldn’t exist.

Telling time in space is difficult, but it is absolutely critical for applications ranging from testing relativity to navigating down the road. Atomic clocks, such as those used on the Global Navigation Satellite System network, are accurate, but only up to a point. Moving to even more precise navigation tools would require even more accurate clocks. There are several solutions at various stages of technical development, and one from Germany’s DLR, COMPASSO, plans to prove quantum optical clocks in space as a potential successor.
