If super massive black holes (SMBH) were given a job description, it would tell them to park themselves in the middle of a massive galaxy and consume as much gas, dust, and even stars as they could. Like teenage boys in front of a well-stocked fridge, they're happy to oblige. However, even voracious SMBHs have limits, and astronomers have watched as one of them reached its limit.

In the 1960s, scientists became acutely aware of a problem with the Universe's "mass budget." Based on the observed rotational curves of galaxies, they determined that about 85% of the Universe's mass was invisible, leading to the theory of Dark Matter. Scientists have also been aware for some time that much of the "normal" or baryonic matter (that which we can see) in the Universe was also unaccounted for. This has prompted multiple efforts to probe the Universe for this "missing" mass, using everything from X-ray emissions and ultraviolet observations of distant quasars to find hints of where it might be hiding.

As NASA prepares for a return to the Moon through the Artemis program, one of the biggest health concerns for astronauts has been lunar dust. The fine, abrasive particles known as the regolith that coat the Moon's surface have long worried scientists, especially after Apollo astronauts experienced respiratory problems after their missions. However, groundbreaking research from the University of Technology Sydney has delivered surprisingly reassuring news: lunar dust is less harmful to human lung cells than previously feared, and significantly less toxic than common Earth based air pollution.

A recent study addresses possible effects from increased rocket launches on the ozone layer.

More and more satellites are being added to Low Earth Orbit (LEO) every month. As that number continues to increase, so do the risks of that critical area surrounding the Earth becoming impassable, trapping us on the planet for the foreseeable future. Ideas from different labs have presented potential solutions to this problem, but one of the most promising, electrodynamic tethers (EDTs), have only now begun to be tested in space. A new CubeSat called the Spacecraft for Advanced Research and Cooperative Studies (SPARCS) mission from researchers at the Sharif University of Technology in Tehran hopes to contribute to that effort by testing an EDT and intersatellite communication system as well as collecting real-time data on the radiation environment of its orbital path.

We might not currently have any technology that would make a space elevator viable on Earth. But that doesn’t mean they wouldn’t work on other bodies around the solar system. One of the most interesting places that one could work is around Ceres, the Queen of the Asteroid Belt, and potentially one of the biggest sources of resources for humanity’s expansion into space. A new paper from researchers at the University of Colorado, Colorado Springs and Industrial CNT, a manufacturer of Carbon Nanotube (one potential material for the space elevator), details just how useful such an elevator could be.

Hycean worlds are also called ocean worlds. They're planets covered in oceans that also have thick hydrogen atmospheres. There are no confirmed Hycean worlds—also called ocean worlds—but many candidates. Even though they're only candidates so far, researchers are curious about their habitability. New research examines the role tidal heating plays in their potential habitability.

The telescope's journey began in the early 1600s when Dutch spectacle maker Jan Lippershey discovered that combining lenses could magnify distant objects. Galileo Galilei quickly improved the designs and became the first to explore the heavens, revealing the Moon's craters, Jupiter’s moons and the rings of Saturn. Over the centuries, telescopes evolved from simple lens combinations to massive ground-based observatories with enormous mirrors, and eventually to space-based instruments like the Hubble Space Telescope that eliminated Earth's atmospheric interference. Today's cutting-edge telescopes, such as the James Webb Space Telescope, use advanced technology to look deeper into space than ever before.
