US EditionRadio Waves from Cosmic Dark Ages May Reveal Dark Matter
Tel Aviv University researchers predict lunar radio signals from hydrogen gas could reveal dark matter properties by observing cosmic dark ages emissions, aiding global space projects.
- Recently, Tel Aviv University researchers led by Prof. Rennan Barkana predicted dense dark matter clumps pulled in hydrogen gas that emitted intense radio waves, offering a new way to investigate dark matter.
- Because it was largely untouched, the cosmic dark ages, about 100 million years after the Big Bang, provided a pristine laboratory where simulations show dark matter formed dense clumps that seeded stars and galaxies.
- To detect these faint emissions, scientists propose radio antennas measuring sky intensity and large arrays like the Square Kilometre Array, while lunar telescopes avoid atmosphere and interference.
- Successful observation would open a new window for testing dark matter theories and reveal clues about invisible structures that seeded galaxies, exciting astronomers eager to tune into the early Universe.
- Prof. Rennan Barkana leads an international team amid a global race to return to the Moon and build the SKA, with recent JWST findings from around 300 million years after the Big Bang underscoring timely observational opportunities.

Desert radio telescope spots signs from the early universe
Long before starlight filled the cosmos for the first time, the young universe may have been simmering, according to a new study. The findings suggest that about 800 million years after the Big Bang, energy from newborn black holes and the fading embers of the first stars was already warming vast clouds of intergalactic hydrogen gas, offering a rare glimpse into a largely uncharted chapter of the universe's youth. Astronomers know that the unive…
Astronomy breakthrough: The mystery of dark matter can be unraveled using radio telescopes
A new study from Tel Aviv University has predicted, for the first time, the groundbreaking results that can be obtained from detecting radio waves coming to us from the early Universe. The findings show that during the cosmic dark ages, dark matter formed dense clumps throughout the Universe, which pulled in hydrogen gas and caused it to emit intense radio waves. This leads to a novel method to use the measured radio signals to help resolve the …
The Universe’s first radio waves could reveal dark matter
Researchers propose that hydrogen gas from the early Universe emitted detectable radio waves influenced by dark matter. Studying these signals, especially from the Moon’s radio-quiet environment, could reveal how dark matter clumped together before the first stars formed. This approach opens a new window into the mysterious cosmic era just 100 million years after the Big Bang.
Universe Radio Waves May Hold The Key To Unlocking Dark Matter's Mystery
Universe Radio Waves May Hold The Key To Unlocking Dark Matter's Mystery. Scientists at Tel Aviv University have proposed an intriguing way to peer into one of the most mysterious chapters in cosmic history - the“dark ages” of the Universe, a time before the first stars
