Is Dark Matter an Illusion? New Study Challenges the Foundations of Cosmology
13 oktober 2025 · 28 min
A new study from the University of Ottawa is shaking up our understanding of the universe. Professor Rajendra Gupta suggests that dark matter and dark energy might not exist at all — instead, the forces of nature themselves are slowly weakening as the universe expands. Lees meer
This idea could explain cosmic mysteries — like why galaxies spin so fast or why the universe is expanding so rapidly — without invoking any unknown particles. Published in Galaxies, the research even suggests the universe may be nearly twice as old as we thought.
If true, this theory could mean that decades of dark matter searches have been chasing a mirage — and that the key to the cosmos lies in the changing fabric of physics itself.

TRAPPIST-1e - Unraveling an Exoplanet's Ocean Potential
13 september 2025 · 29 min
Recent research using the James Webb Space Telescope (JWST) has focused on the exoplanet TRAPPIST-1e, an Earth-sized world that orbits a red dwarf star and is located in the habitable zone. Scientists are investigating the presence of an atmosphere, which is crucial for the existence of liquid water on its surface, whether as a global ocean or vast areas of ice. While initial results suggest the possibility of an atmosphere, researchers have ruled out the existence of a primordial hydrogen-based atmosphere. Instead, the presence of a secondary atmosphere containing greenhouse gases, such as carbon dioxide, could keep the planet warm and make liquid water possible, despite the unique characteristics of the TRAPPIST-1 system. Future JWST observations will continue to refine our understanding of this and other exoplanets. Lees meer

Giant Stars, Solar Electrons, and Gravitational Waves as an Alternative to Cosmic Inflation
3 september 2025 · 40 min
Gisnt Binary Stars Locked in Rapid Orbit: Lees meer
Astronomers are studying a massive, binary star system called NGC 3603-A1, located in a dense, star-forming region. One star is 93 times the sun's mass and the other is 70 times, making them one of the heaviest pairs known. They orbit each other in just 3.8 days, and their intense interaction causes them to change, with evidence showing the smaller star has stolen material from the larger one. The discovery was sparked by an undergraduate student's observation of old Hubble data. Studying this system helps scientists understand how massive stars evolve and how they might eventually collapse into black holes, which could then merge and produce detectable gravitational waves.
Solar Orbiter Reveals Origins of Fast Solar Electrons:
The Solar Orbiter spacecraft has discovered two distinct origins for the Sun's fast-moving electrons, known as solar energetic electrons. Some are produced in sharp bursts from solar flares, while others are released in a slower, broader wave from much larger coronal mass ejections. By observing these events close to the Sun, scientists were able to distinguish between the two types and account for how the electrons get scattered and delayed on their journey through space. This research has practical implications for space weather prediction, as these particles can be dangerous to satellites and astronauts.
Gravitational Waves as an Alternative to Cosmic Inflation:
A new study challenges the theory of cosmic inflation, which proposes that the universe underwent a rapid expansion after the Big Bang. Instead, the researchers suggest that gravitational waves, which are ripples in space-time, could explain the origins of cosmic structures like galaxies and stars. This new model is appealing because it relies on well-established physics and doesn't require unverified, hypothetical elements. The study suggests that the interplay between gravity and quantum mechanics alone might be sufficient to accoun…

Bennu: A Time Capsule from the Early Solar System: Asteroid Bennu is made of material from different regions of the solar system and even from other stars. NASA’s OSIRIS-REx mission returned samples from Bennu in 2023, revealing ancient stardust, water-altered minerals, and organic molecules. These findings show Bennu preserves a rich record of early solar system history, including evidence of space weathering and chemical changes driven by water. Because the samples were collected directly in space, they offer an uncontaminated glimpse into the building blocks of planets and life. Lees meer
Hunting Cosmic Rays with Neutrinos: Scientists are using the IceCube observatory in Antarctica to detect neutrinos and trace the origins of cosmic radiation. Neutrinos can travel across the universe without much interference, making them ideal messengers. New fast and accurate data analysis methods now allow telescopes worldwide to respond quickly to neutrino detections. The improved algorithms also helped scientists rule out some earlier suspected sources, like tidal disruption events. While the exact source of cosmic rays remains unknown, the new tools mark important progress.
Before the Big Bang: Simulating the Unknown: Physicists are using computer simulations to explore what may have happened before the Big Bang. Standard equations from general relativity break down at the universe's beginning, but numerical relativity can handle these extreme conditions. Originally developed to simulate black hole collisions, this technique may help test ideas like cosmic inflation, cosmic strings, the multiverse, or a cyclical universe. As computing advances, this method could bridge gaps between cosmology and gravitational physics and offer insights into the origins of our universe.

Astronomers discovered the most distant confirmed black hole, dating back 13.3 billion years. It lies in a tiny, bright galaxy called CAPERS-LRD-z9, and challenges current theories by being unexpectedly massive for such an early time. 2. Cosmic Grapes Galaxy:
A galaxy from 900 million years after the Big Bang was found to have at least 15 clumps of stars forming simultaneously, defying models of early galaxy formation and suggesting clumpy structures may have been common. 3. Tilted Sun-Like Stars:
A study shows that about one-third of young Sun-like stars are born with their spin axes tilted relative to their planet-forming disks, meaning some planetary system misalignments happen from birth, not later.

Simulating the Universe’s First Light with SKA-Low Scientists created an advanced simulation of what the SKA-Low radio telescope will detect when it starts observing the early universe. The project focuses on capturing ultra-faint 21-cm hydrogen signals from the Cosmic Dawn and the Epoch of Reionization—eras when the first stars and galaxies lit up the cosmos after a long dark age. This simulation includes realistic foreground interference, technical noise, and cosmic signals, helping researchers refine data analysis techniques before SKA-Low becomes operational. The goal is to study the universe’s first light with unmatched detail.
Through Cosmic Lenses: Unlocking the Universe with Light and Gravity Researchers are using a technique called multi-messenger gravitational lensing, which combines gravitational waves and electromagnetic signals bent by massive cosmic structures, to observe distant cosmic events from multiple perspectives. This emerging field helps answer big questions about dark matter, gravity, and the expansion of the universe. International collaborations and new instruments like the Vera C. Rubin Observatory and the LIGO-Virgo-KAGRA network are central to this effort, aiming for major breakthroughs in the coming decade.
Ancient Water Ice Found Around Young Star Suggests Pre-Solar Origins Astronomers have detected semi-heavy water ice (with deuterium) around a young star similar to the early Sun, thanks to the James Webb Space Telescope. This finding supports the theory that much of the water in our solar system formed in cold, dark interstellar clouds long before the Sun existed.
