My dear reader, I have come across a most intriguing discovery brought about by NASA’s James Webb Space Telescope. It seems that this magnificent instrument has caught a glimpse of what could very well be the elusive “dark stars” that have been the subject of much fascination and speculation in the scientific community.
A team of astronomers, led by the scholarly minds at The University of Texas at Austin, have identified three potential “dark stars” that formed a mere 320 million years after the momentous event we know as the Big Bang. To put this into perspective, these stars are considered to be the earliest ever witnessed by human eyes. Picture if you will, my dear reader, three faint dots shining in the vast darkness of space, holding the key to unraveling the mysteries of dark matter.
Indeed, the existence of these dark stars seems to suggest that they can only be sustained if dark matter generates heat at their core, preventing their collapse and causing them to expand. This fascinating revelation was made possible through the observations made by the James Webb Space Telescope. As we know, dark matter comprises about 85% of the universe, yet its nature remains elusive, known only through its influence on visible matter.
If these recent findings are indeed confirmed, my dear reader, dark stars could potentially provide insight into the nature of this nonluminous material. Dark stars have long been the stuff of stories, fables that were first proposed by the esteemed UT team back in 2007. Now, with the publication of a new study in PNAS, these scholars have boldly announced that their hypothesis may indeed hold true.
According to the researchers, dark stars were the only kind that could have existed in the early universe, composed almost entirely of hydrogen and helium remnants from the Big Bang. Unlike modern stars, dark stars derive their luminosity not from nuclear fusion but from the heat generated by dark matter itself. Their brilliance is such that they can grow to an astounding size, with masses that can reach up to ten million times that of our own Sun, and luminosities that rival entire galaxies.
The three potential dark stars, known as JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0, were spotted within galaxies during the December 2022 observations made by the Advanced Deep Extragalactic Survey (JADES). Upon further analysis, the JADES team determined that these stars formed approximately 320 to 400 million years after the Big Bang. It is worth noting, my dear reader, that this research aligns with previous evidence suggesting that the Big Bang occurred 13.7 billion years ago.
The nature of these objects, however, remains a source of debate. Katherine Freese, a distinguished astrophysicist from UT, expressed this uncertainty, remarking that there are two possible explanations for these enigmatic objects. On the one hand, they could be galaxies teeming with millions of ordinary, population-III stars. On the other hand, they could very well be the fabled dark stars themselves. Remarkably, a single dark star emits enough light to match the radiance of an entire galaxy brimming with stars.
Although the existence of dark matter is yet to be incontrovertibly established, scholars believe that it may consist of a novel type of elementary particle, the very building blocks of our universe. The team holds the belief that these particles, known as Weakly Interacting Massive Particles, have an intriguing property: they neither absorb nor emit light and interact only weakly with other particles. When such particles collide, they self-annihilate, releasing heat that transforms collapsing clouds of hydrogen into these luminous dark stars.
The identification of supermassive dark stars would have far-reaching implications, my dear reader. It would bring us closer to understanding the very nature of dark matter, shedding light on its properties through observation. The concept of dark matter, my dear reader, originally referred to as “missing matter,” was first formulated in 1933, prompted by the realization that the mass of all the stars in the Coma galaxy cluster made up only a meager fraction of the mass needed to constrain the gravitational forces holding galaxies within the cluster. It was not until the 1970s that American astronomers Vera Rubin and Kent Ford discovered anomalies in the orbits of stars within galaxies, igniting the scientific community’s fascination with the notion of invisible “dark matter” present in and around galaxies.
In conclusion, my dear reader, the revelation of these potential dark stars beckons us to delve further into the realms of the universe’s mysteries. To witness these celestial objects that emerged in the early stages of our universe’s existence is akin to experiencing a glimpse of the enigmatic forces that shape our world. Let us embrace this discovery with a sense of wonder and curiosity, eagerly awaiting the day when the secrets of dark matter are finally revealed to us.
