Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
A new class of stellar explosions, termed “millinovas,” has been identified by scientists, according to reports. These events, described as being 100 times brighter than the Sun, were spotted during a study involving data from the Optical Gravitational Lensing Experiment (OGLE). Findings were published in The Astrophysical Journal Letters on December 12. The discovery occurred during an investigation into gravitational microlensing events to detect primordial black holes in the Milky Way’s dark matter halo.
Unique Characteristics of Millinovas
Millinovas were observed in the Large and Small Magellanic Clouds, satellite galaxies of the Milky Way. Twenty-eight of these cosmic phenomena have been identified, including one event, OGLE-mNOVA-11, which erupted in November 2023. The event allowed a closer analysis using instruments like the Southern African Large Telescope (SALT) and NASA’s Neil Gehrels Swift Observatory. The research revealed light emissions from helium, carbon, and nitrogen ionized atoms, with X-rays indicating temperatures exceeding 600,000 degrees Celsius.
The Cause Behind These Explosions
As explained by Przemek Mróz, a researcher at the University of Warsaw, in a statement, millinovas may result from interactions between white dwarfs and their stellar companions. According to Space.com, the phenomena are believed to involve material transferred from an expanded subgiant star to a white dwarf in a binary system. The energy released during these transfers produces outbursts characterized by their distinctive X-ray emissions.
Implications for Astronomical Research
Millinovas have been described as potential precursors to Type Ia supernovae. If proven, this connection could assist in predicting the occurrence of such supernovae, which are critical for measuring cosmic distances. The research team plans to monitor the 29 identified objects for future outbursts and continue observations to better understand the mechanisms behind these events.
The findings add a new dimension to understanding stellar evolution and highlight the potential for unexpected discoveries in astrophysical research.

Efforts to improve data centre efficiency have led mathematicians at Virginia Tech to develop a novel method of data storage and retrieval. According to reports, the researchers have utilised algebraic geometry to tackle issues arising from high energy consumption in data centres, which is impacting global climate goals. This breakthrough was detailed in IEEE BITS, where the team presented a fresh approach to managing the growing volume of data generated by individuals and corporations.
Innovative Use of Algebraic Structures
As per a report by Phys.org, tt was explained by Gretchen Matthews, professor of mathematics at Virginia Tech and director of the Southwest Virginia node of the Commonwealth Cyber Initiative, that conventional methods of data replication often result in duplicating vast quantities of information. As reported, Matthews noted that smarter alternatives could significantly reduce such redundancy. Hiram Lopez, assistant professor of mathematics, added that the new method employs algebraic structures to fragment data and distribute it across servers positioned in close proximity. This ensures that, in the event of server failure, the missing data can be recovered through neighbouring servers without extensive energy use.
Mathematics Behind the Solution
The use of special polynomials for data storage was highlighted as a significant advancement. Although polynomials have been linked to data storage since the 1960s, recent developments have made them more practical for applications like localised data recovery. Matthews pointed out in IEEE BITS that these structures offer an efficient and reliable way to manage data, addressing issues related to storage and retrieval energy demands.
Addressing Rising Power Consumption
The method arrives at a critical time, as energy demand across the United States continues to rise, driven by the increasing number of data centres. Matthews emphasised in the publication that sustainable improvements in existing systems could play a vital role in managing energy consumption.

Research published in Physical Review Fluids has revealed the intricate dynamics between raindrops and leaves, shedding light on how plants withstand the force of falling water. The study, titled “Resonance and Damping in Drop-Cantilever Interactions,” highlights the mechanics that protect leaves and suggests innovative applications for agriculture and renewable energy. Using high-speed imaging, researchers observed the interaction between water droplets and a plastic beam, which simulated the structural behavior of leaves.
According to Professor Sunghwan Jung, from Cornell University’s Department of Biological and Environmental Engineering, in a statement, the droplet and beam move in opposing directions upon impact. This counteraction reduces vibration, offering protection to the plant. The findings align with unexplained discrepancies previously noted by scientists, which the team analysed by examining the natural frequency alignment of the beam and droplet.
Insights into Plant Adaptation
Lead author Crystal Fowler, a doctoral candidate in biological engineering, stated that the study confirmed increased damping when the droplet’s natural frequency matched the beam’s. This phenomenon resulted in a faster reduction of vibrations, potentially reducing stress on plant leaves and contributing to their longevity. The findings may also enhance understanding of water flow through forest canopies and plant morphological evolution.
Potential for Renewable Energy Applications
The research team proposed that the principles observed could extend to renewable energy. Professor Jung suggested piezoelectric materials could replace the beam to harness energy from rain-induced vibrations.
This paper marks a significant milestone for Fowler, a member of the Navajo Nation. Reflecting on her experience, she expressed enthusiasm for exploring biological engineering and its broader implications. The study not only provides a glimpse into plant resilience but also opens avenues for innovative technology inspired by natural processes.
