LONDON – Astronomers have identified an extraordinary radio signal, emanating from a staggering 8 billion years in the past. This ancient cosmic whisper contains immense energy levels previously thought impossible.
The phenomenon,known as a “fast radio burst” or FRB,was detected for a mere millisecond. Designated FRB 20220610A, this burst of electromagnetic radiation in the radio frequency range released an amount of energy equivalent to what our sun produces in 30 years.
The precise nature of these intense, short-lived explosions remains a subject of ongoing research. However, scientists theorize they could be linked to cataclysmic events such as the merging of galaxies, which often trigger the birth of new stars.
these powerful signals also serve a crucial scientific purpose. They can be used to “weigh” the intervening space, allowing astronomers to measure the mass of elements found between galaxies, a calculation that is or else incredibly difficult to perform.
Ryan shannon, a co-author on the study, highlighted the significance of these findings.”If we count the amount of normal material in the universe-the atoms that make us all-we find that more than half of what should be there now has been lost,” he explained. Understanding FRBs helps unravel this cosmic enigma.
Understanding Fast radio Bursts
Fast Radio Bursts (FRBs) are intense, millisecond-long flashes of radio waves from deep space. Thier origins are still largely a mystery, but potential sources include highly magnetized neutron stars like magnetars, or even the aftermath of neutron star mergers.
The study of FRBs is vital for cosmology, as the signals can carry facts about the matter that lies between the source and Earth. By analyzing how the signal is dispersed, scientists can map the distribution of matter, including mysterious “dark matter,” across the universe.
frequently Asked Questions about Ancient Radio Signals

- What are the suspected causes of fast radio bursts?
- The leading theories for the cause of fast radio bursts include events involving highly
What implications does detecting radio signals from 8 billion years ago have for our understanding of the first stars (Population III stars)?
Ancient Echoes: Astronomers Detect Radio Signals From 8 Billion Years Ago
The Deepest Radio Signals yet: A Cosmic time Capsule
In a groundbreaking finding, astronomers have detected radio signals originating from a staggering 8 billion years ago – a period when the universe was just over a billion years old. This represents the most distant confirmed radio emission ever observed,offering an unprecedented glimpse into the early universe and the era of the first stars and galaxies.The research, published in Nature, utilizes data from the Low-Frequency Array (LOFAR) telescope, a pan-European radio telescope network. This detection pushes the boundaries of our understanding of cosmic dawn, the period when the universe transitioned from a dark, neutral state to one filled with light-emitting structures.
Understanding the Significance of 8 Billion Light-Years
Eight billion light-years isn’t just a large distance; it’s a journey back in time. Because light takes time to travel, observing objects at such vast distances means we are seeing them as they existed billions of years in the past. This specific signal originates from a time when the universe was undergoing notable changes:
Formation of First Stars: The earliest stars, vastly different from those we see today, were beginning to ignite. These Population III stars were likely massive and short-lived, playing a crucial role in reionizing the universe.
Galaxy Formation: The seeds of galaxies were coalescing,driven by gravity and dark matter. Observing these early structures provides insights into how galaxies like our Milky Way formed.
Hydrogen Reionization: The universe was initially filled with neutral hydrogen. The radiation from the first stars and galaxies gradually ionized this hydrogen, making the universe transparent to light. Detecting the 21-centimeter line of neutral hydrogen is a key goal in studying this epoch.
How Were These Ancient Signals Detected?
The detection wasn’t straightforward. The signals are incredibly faint and buried within a sea of radio noise. Astronomers employed sophisticated data processing techniques to isolate the signal from the background. Key to this success was:
- LOFAR’s low-Frequency Capabilities: LOFAR is specifically designed to detect low-frequency radio waves, which are less affected by intervening matter and can travel vast distances.
- Foreground Removal: Radio emissions from our own galaxy and other sources needed to be meticulously removed to reveal the faint cosmic signal. This is a major challenge in radio astronomy.
- Statistical Analysis: The signal wasn’t a clear, distinct peak. rather, it was identified through subtle statistical variations in the radio background.
The 21-Centimeter Line and the Cosmic Dawn
The detected signal is believed to be related to the 21-centimeter line of neutral hydrogen.This specific wavelength of radio emission is emitted when the electron in a hydrogen atom flips its spin. During the cosmic dawn, as the first stars and galaxies began to emit ultraviolet radiation, they ionized the surrounding hydrogen, altering the 21-centimeter signal.
Redshift: Due to the expansion of the universe, the wavelength of this signal has been stretched (redshifted) over billions of years, shifting it into the low-frequency radio range detectable by LOFAR.
Mapping the Early Universe: By mapping the distribution of the 21-centimeter signal, astronomers hope to create a 3D map of the early universe, revealing the locations of the first stars and galaxies.
Implications for Cosmology and Astrophysics
This discovery has profound implications for our understanding of the universe:
Testing Cosmological Models: The observed signal provides a crucial test of our current cosmological models, helping to refine our understanding of the universe’s composition and evolution.
Understanding Dark Matter: The formation of the first structures was heavily influenced by dark matter. Studying the early universe can provide clues about the nature of this mysterious substance.
future Research with SKA: The Square kilometre Array (SKA), a next-generation radio telescope currently under construction, will be even more sensitive and capable of detecting fainter signals from the early universe. This discovery paves the way for more detailed studies with the SKA.
Challenges and Future Directions in Radio Cosmology
Despite this breakthrough, significant challenges remain:
signal Strength: The signals from the early universe are incredibly weak, requiring increasingly sensitive telescopes and sophisticated data analysis techniques.
Foreground Contamination: Separating the cosmic signal from foreground emissions remains a major hurdle.
Theoretical Modeling: Accurate theoretical models are needed to interpret the observed signals and understand the physical processes occurring in the early universe.
Future research will focus on:
Confirming the Detection: Self-reliant observations with other radio telescopes are needed to confirm the initial detection.
Mapping the Signal: Creating a detailed map of the 21-centimeter signal to reveal the distribution of the first stars and galaxies.
Searching for Similar Signals: Looking for similar signals from other regions of the early universe.

Common people call a cold a disease of the respiratory tract, caused, as was previously believed, by hypothermia of the body. Scientists now know that this condition is caused by a viral (sometimes mixed with bacterial) infection of the respiratory tract.
What mistakes do people most often make when treating colds?
- They don’t get vaccinated. Now vaccination is the only reliable method of preventing influenza and covid. It is important to understand that it works effectively at the population level, but for each individual it only reduces the risk of infection. It’s never too late to get vaccinated.
- Antiviral drugs are used. Currently, there are no antiviral drugs that would effectively fight any ARVI. Yes, drugs once morest influenza and Covid exist, but they are not active once morest other viruses and can only be used following receiving a positive result from a rapid test for these diseases.
- Taking antibiotics without indications or for preventive purposes. You should not take such drugs without undergoing appropriate tests and a doctor’s recommendation.
- Tolerates high temperatures when you feel unwell. It is important to consider your condition. If your health worsens already at 37.1, then you need to bring down this temperature; if 38.6 is tolerated normally, you don’t have to take antipyretics.
- Do not take cold medications during pregnancy and lactation. In fact, it is not necessary to suffer in such cases. Now there are many medications that do not pose a danger to pregnant and breastfeeding women. So you just need to see a good doctor.

Po calculations American experts, since 2011 in the United States every day 10 thousand people cross the 65-year-old threshold. According to forecasts, by 2035 this age group will become more numerous than children. By that time, the healthcare system will be so overloaded that it will not be able to cope with the treatment of chronic diseases of old age.
