CubeSats have a lot of advantages. They are small, inexpensive, and easily reproducible. But those advantages also come with significant disadvantages - they have trouble linking into broader constellations that allow them to be more effective at their observational or communication tasks. A team from the University of Albany thinks they might have solved that problem by using a customized calibration algorithm to ensure the right CubeSats link up together.

Located on a mountaintop in Chile, the nearly complete Vera C. Rubin Observatory will capture the Universe in incredible detail. This week saw another huge step for the observatory with the installation of the car sized - yes car sized - LSST camera onto the Simonyi Survey Telescope. The camera is the largest ever built, weighing in at over 3,000 kilograms with an impressive 3,200 megapixels. Coupled to the 8.4 metre optics of the Rubin will allow it to capture everything that happens in the southern sky, night after night.

On March 11, the California skyline was once again treated to the launch of the SpaceX Falcon 9 rocket from the Vandenberg Space Force Base. It carried two missions into space; SPHEREx to study the origins of the Universe and the molecular clouds of the Milky Way and four other satellites making up PUNCH. This latter mission is tasked with exploring how the Sun’s outer atmosphere causes the solar wind.

Electrolysis has been a mainstay of crewed mission designs for the outer solar system for decades. It is the most commonly used methodology to split oxygen from water, creating a necessary gas from a necessary liquid. However, electrolysis systems are bulky and power-intensive, so NASA has decided to look into alternative solutions. They supported a company called Precision Combustion, Inc (PCI) via their Institutes for Advanced Concepts (NIAC) grant to work on a system of thermo-photo-catalytic conversion that could dramatically outperform existing electrolysis reactors.

If you're a regular visitor to Universe Today, you've probably noticed that the website looks dramatically different. Simpler, cleaner, without all those pesky intrusive ads. We're in a new era, now. Here's what happened, why I decided to remove the ads from the site, and what you can expect going forward.

Dark matter - that mysterious, unknown stuff that's detectable only by its effect on other matter - seems to be sparking strong emissions at the heart of the Milky Way Galaxy.

Dutch astronomer Christiaan Huygens was the first to discover a Saturnian moon way back in 1655. Thanks to his skill as a lens grinder and polisher, he was the first person to see Titan. Over the centuries, we've discovered many more moons orbiting the ringed planet. In a surprising announcement on March 11th, the Minor Planet Center announced the discovery of 128 more moons, almost doubling the previous number.

Our local star, the Sun has been under the watchful gaze of ESA’s Solar Orbiter since its launch in 2020. It’s been slowly getting closer and grabbing images using its Extreme Ultraviolet Imager (EUI) which citizen scientists have been stitching together into wonderful time-lapse videos. A recent video covers just 15 minutes of real time but within, you can see an M-Class flare that was unleashed by the Sun. The flares can produce brief radio blackouts here on Earth.

Of all the moons in the Solar System, Europa is perhaps one of the most fascinating. With a thick ice shell surrounding a subsurface ocean, astrobiologists hope maybe there is life down there! Finding a way through the ice to explore what’s below is one of the biggest challenges. It’s possible however that the vital chemicals from life could find their way to the surface and through out into space. A new paper proposes an ultraviolet laser could be used to cause amino acids to fluoresce giving away their presence.

The closest single star to our own Solar System is Barnard’s Star. It’s 6 light years away and astronomers have just found four new mini-Earth planets in orbit around this red dwarf star. The discovery was made with the MAROON-X instrument on the Gemini North telescope which makes use of the radial velocity method to detect exoplanets. One planet was found in August 2024, the other three were only just added.
