New simulations connect the first stars to cosmic fingerprints still visible today
Confirmed
In Short: High-performance computing (HPC) systems are aiding these complex simulations, accelerating scientific discovery and connecting research across a global network.
Researchers have discovered fingerprints on ancient clay beads, pushing back the timeline of symbolic behavior by thousands of years.
The beads, found at Natufian sites in Israel, date back 14,000 years and contain 50 fingerprints, many belonging to children.
According to Popularmechanics, these findings suggest that the symbolic revolution began earlier than previously thought, even as communities were still primarily hunting and gathering.
The fingerprints offer archaeologists the first direct identification of the makers of these ancient ornaments, providing insights into the social and cultural practices of early human societies.
In a separate study, astronomers are using simulations to understand dark matter, focusing on streams of stars in our galaxy.
These simulations treat dark matter as a simple, uniform halo and help explain the gravitational interactions that cause stars to spray out in streams orbiting larger galaxies.
By measuring specific chemical fingerprints, researchers concluded that comet 3I/ATLAS likely formed in the outskirts of an old star system.
Simulations of overmassive black holes predict a spectrum that matches observed spectra of little red dots, adding complexity to theories about the first stars.
Anna de Graaff of the Max Planck Institute suspects that many of these dots are giant stars with hidden black holes.
These findings highlight the ongoing advancements in understanding both ancient human practices and cosmic phenomena.
The research on beads and stars contributes to a broader understanding of human and cosmic evolution, revealing new insights into the past and present.
What this adds
The fingerprints on the beads provide a unique and direct link to the creators of these ornaments, offering unprecedented insight into early human societies.
The study of dark matter through star streams adds a new dimension to our understanding of cosmic structure and the behavior of dark matter.
The use of HPC systems in these simulations underscores the importance of advanced computing in advancing scientific research and discovery.

What's still developing
- Some simulations put too many low clouds over the Southern Ocean, yet still underestimate how much heat reaches the surface below.
- So astronomers continue to rely upon indirect evidence and computer simulations to help us understand the detailed properties of dark matter.
- A new study in The Astrophysical Journal adds to the simulation column, but with a bit of a twist.[^1] Most dark matter simulations look at large-scale cosmic structure.

- This idea of a measurable signature or 'fingerprints' in the present-day solar interior was explored by research published today in Monthly Notices of the Royal Astronomical Society.
- Researchers also found that such a world could survive its passage through the Sun's outer layers while losing very little mass, which suggests that planets may leave detectable fingerprints inside their host stars long after they have disappeared.
- Now a new study has gone a step further by suggesting that such an event may have left behind detectable clues inside our star which could still be visible today.
- " The field of interstellar objects is still very new, and we do not really know what to expect. Every time a new one is discovered, we have new surprises," Opitom concludes. [1] A team lead by Salazar-Manzano and Paneque-Carreño used the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, to measure deuterated (or semi-heavy) water in 3I/ATLAS.
