Electronics engineering students from Ventspils University of Applied Sciences (VUAS) developed a probe that carried a can of “Rudy’s Kombucha” into near space, reaching an impressive altitude of 28,690 meters – nearly 30 kilometers above the Earth’s surface. While trying to locate the probe afterward, the students encountered major GPS signal disturbances across the Kurzeme region, so they called on radio amateurs for assistance. Working together, they successfully located the probe near Dobele. The space mission probe was equipped with a GoPro camera that captured both the launch and the breathtaking flight. After the controlled explosion of the probe’s balloon at nearly 30 kilometers altitude, a parachute opened, ensuring the can’s safe return to Earth. The probe was launched from Ventspils airfield and, after flying approximately 140 kilometers, landed near Dobele. Jānis Šate, Director of the Electronics Engineering study program at Ventspils University of Applied Sciences, explained: “The company knew that our students develop probes, and they had the idea to attach a beverage can and launch it into space. Technically, it’s more accurate to say it was launched into the stratosphere. We discussed it in August, and within a few months, the electronics engineering students built the probe. It’s a group project in the third year of studies, and this collaboration added extra value. The most challenging part of launching the probe is creating the electronic system attached to the parachute and helium balloon. The balloon rises to about 30 kilometers, where air pressure drops, the balloon bursts, and the probe descends to Earth. Launching it is easy – the hard part is tracking and recovering it afterward. A GPS navigation system is required to continuously transmit the probe’s location. The students’ task was to design an electronic system that can operate in the stratosphere, where temperatures drop to –40°C.” “We coordinated the launch with the Civil Aviation Agency since air traffic is affected, and we also arranged it with Ventspils Airport. Eventually, the probe was found near Dobele, though there were unexpected complications – due to the global situation, GPS communications are regularly disrupted from Königsberg (Kaliningrad, Russia). Unfortunately, we launched on one of those days when signal interference over Kurzeme and the Baltic Sea was particularly strong. That meant that when the probe ascended above ten kilometers, our system showed it was no longer over Kuldīga, but over Kaliningrad. From there, spoofed GPS signals were being transmitted to mislead moving objects.

In October, VUAS COLOURS WP5, headed by Lasma Asme, joined other representatives from COLOURS partner universities gathered at Garage33, Paderborn University, Germany, for a dynamic CoLab dedicated to Mental Health, Body Image, and Equality, Diversity, and Inclusion (EDI). The three-day event, which is part of the COLOURS CoSpace initiative, brought together students, researchers, and staff from across Europe to exchange perspectives and co-create innovative approaches under the smart specialisation area of Health and Well-being. Participants from a very diverse background, under the moderation of Dr Christine Hante-Koch and Dr Alena Diedrich, discussed how issues like body dissatisfaction, eating disorders, anxiety, and depression are closely connected and how promoting a positive body image can make a real difference for people’s health. Using design thinking processes, the group also worked on the importance of creating fair and inclusive support systems that meet the needs of different communities, including women, LGBTQ+ individuals, and people facing disabilities, financial struggles, or migration challenges. The participants were divided into 4 groups and had cases ranging from how to deal with women who survived breast cancer, to isolated international students living in other countries, and how to make gamers more active while utilizing their special skills and enlarging their comfort zone. At the end of the event, each group pitched their ideas, solutions, and next steps. These solutions were evaluated and challenged by a panel of experts from multiple disciplines, with the example of Martin Persson, Professor of Health Sciences at Kristianstad University. The CoLab encouraged teamwork, creativity, and cultural exchange. The ideas developed in Paderborn will help shape future COLOURS activities and strengthen collaboration between partner universities committed to building healthier and more inclusive learning environments and society at large.

A wide US – Europe network of radio telescopes including observing a faraway radio galaxy discovers a small dark object. It is just a pinch in their data but it signifies that low-mass dark matter clumps are widespread, verifying theories of the Universe’s structure and evolution. The telescopes used include those of VUAS institute “Ventspils International Radio Astronomy Centre” (VIRAC). An international team of astronomers has found a low mass dark object in the distant Universe, not by directly observing any emitted light, but by detecting its tiny gravitational distortion of the light from another distant galaxy. This mysterious object has a mass of about one million times that of our Sun, and its discovery seems consistent with the current best theory about how galaxies like our own Milky Way formed. “Since we can’t see dark matter objects directly, we instead use very distant galaxies as a backlight to look for the gravitational imprints of such objects.” “Hunting for dark objects that don't seem to emit any light is clearly challenging,” said Dr. Devon Powell at the Max Planck Institute for Astrophysics (MPA) and lead author of the study published in Nature Astronomy. “Since we can’t see them directly, we instead use very distant galaxies as a backlight to look for their gravitational imprints.” Dark matter is an enigmatic form of matter not expected to emit light, yet it is essential to understanding how the rich tapestry of stars and galaxies we see in the night sky evolved. As a fundamental building block of the universe, a key question for astronomers is whether dark matter is smooth or clumpy, as this could reveal what it is made of. As dark matter cannot be seen, its properties can only be determined by observing the gravitational lensing effect, whereby the light from a more distant object is distorted and deflected by the gravity of the dark object, creating a characteristic arc in the processed image. The team used a network of telescopes from around the world, including the Green Bank Telescope (GBT), the Very Long Baseline Array (VLBA) and the European Very Long Baseline Interferometric Network (EVN). The latter includes the VIRAC radio astronomical observatory in Irbene. The data from this international network were correlated at the Joint Institute for VLBI ERIC (JIVE) in the Netherlands, forming an Earth-sized super-telescope that could capture the subtle signals of gravitational lensing by the dark object. They discovered that the object has a mass a million times greater than that of our Sun and is located in a distant region of space, approximately 10 billion light years from Earth, when the universe was only 6.5 billion years old. “From the first high-resolution image, we immediately saw a pinch in the gravitational arc, which is the tell-tale sign that we were onto something.” This is the lowest mass object to be found using this technique, by a factor of about 100. To achieve this level of sensitivity, the team had to create a high-fidelity image of the sky using radio telescopes located around the world. Professor John McKean from the University of Groningen (RuG), the University of Pretoria (UP) and the South African Radio Astronomy Observatory (SARAO), who led the data collection and is the lead author of a companion paper, said: “ From the first high-resolution image, we immediately saw a pinch in the gravitational arc, which is the tell-tale sign that we were onto something. Only another small clump of mass between us and the distant radio galaxy could cause this.” To analyse the massive dataset, the team had to develop new modelling algorithms that could only be run on supercomputers. “The data are so large and complex that we had to develop new numerical approaches to model them. This was not straightforward as it had never been done before,” said Dr Simona Vegetti at MPA. “We expect every galaxy, including our own Milky Way, to be filled with dark matter clumps, but finding them and convincing the community that they exist requires a great deal of number crunching,” she continued. The team applied a special technique called gravitational imaging, which allowed them to ‘see’ the invisible dark matter clump by mapping its gravitational lensing effect against the radio-luminous arc. “We expect every galaxy, including our own Milky Way, to be filled with dark matter clumps” “Given the sensitivity of our data, we were expecting to find at least one dark object, so our discovery is consistent with the so-called ‘cold dark matter theory’ on which much of our understanding of how galaxies form is based,” said Powell. “Having found one, the question now is whether we can find more and whether the numbers will still agree with the models.” The team are now analysing the data further to better understand what the mysterious dark object could be, but they are also looking into other parts of the sky to see if they can find more examples of such low-mass dark objects using the same technique. If they continue to find such mysterious objects in other parts of the universe, and if they really turn out to be completely devoid of stars, then some theories of dark matter may be ruled out.
