The problem to be solved by science is to discover the relationship between definite facts and phenomena in nature, and to establish theories to link facts and phenomena; science is mainly dealing with unknown areas.
In recent years, cosmologists have imposed tight constraints on dark matter and dark energy densities, even as their fundamental nature remains elusive. A key goal is creating precise maps of dark matter distribution across and within galaxies. In a groundbreaking study, researchers at ETH Zurich me
In the late 14th century, Europe endured one of its darkest chapters: the second Black Death pandemic, which claimed over half the continents population. To illuminate the origins and evolution of the plague bacterium Yersinia pestis, scientists have sequenced ancient genomes from pandemic-era rem
Standard cosmological models peg the universes age at about 13.8 billion years, derived from cosmic microwave background studies and expansion acceleration data. Yet, a lingering puzzle in cosmology is stars that seem older than the cosmos itself—the so-called age paradox. HD 140283, or Methuselah S
At first glance, medicine and astrophysics seem worlds apart. Yet, technologies from astrophysics have repeatedly enhanced medical diagnostics. For instance, photonic algorithms from telescopes have refined breast cancer detection. Now, these fields unite again to tackle Alzheimers disease.A deep le
As particle physics pushes toward higher energy levels, experts are exploring innovative solutions to surpass the LHC. One bold idea: constructing a collider on the Moon, leveraging its extreme cold, natural vacuum, and gravitational alignment with Earth.Our deepening understanding of the universe d
Earth is an oblate spheroid—a fact established centuries ago and irrefutably confirmed by the Soviet Unions Sputnik 1 satellite in 1957. Since then, countless observations, data, and images have reinforced this. Yet, modern Flat Earth proponents claim its a disc, devising theories to explain spheric
Earths vibrant sunsets, painted in pinks, oranges, and yellows, captivate photographers and skywatchers alike. But these spectacles arent unique to our world—sunsets occur across the solar system, each colored by its planets unique atmosphere. What hues dominate on Mars, Uranus, or Titan?The colors
Earths geomagnetic field, generated by convective motions in its molten iron core, acts as a vital shield against cosmic rays and solar wind particles. Yet, a notable weakness known as the South Atlantic Anomaly (SAA) over South America and the South Atlantic Ocean allows these particles to penetrat
While most stars astronomers observe reside within galaxies, intergalactic stars drift independently, unbound by any galaxys gravity. These solitary stars vary in distance from Earth—but which holds the record for farthest detected?The champion is MACS J1149 Lensed Star 1, commonly known as Icarus,
In galaxies, intense streams of high-energy particles arise from the stellar winds of massive stars or the gravitational influence of supermassive black holes, forming what we call galactic winds. In starburst galaxies with rapid star formation, colliding supernova winds create vast bubbles of ultra
In Type Ia supernovae, a white dwarf in a binary system accretes material until it surpasses the critical Chandrasekhar limit of about 1.44 solar masses, triggering runaway nuclear fusion and a cataclysmic explosion. Typically, this obliterates the white dwarf entirely—but in rare cases, a stellar r
Researchers at the University of Warwick have developed a groundbreaking cancer treatment using iridium, a rare heavy metal abundant in meteorites but scarce on Earths surface.Iridium occurs in trace amounts on Earth, mostly concentrated near the planets core. Elevated levels in soil layers signal p
The universes cosmic catalog is filled with remarkable structures, including superbubbles—enormous cavities spanning hundreds of light-years, brimming with ultra-hot atomic gases heated to several hundred million degrees. These features emerge in the interstellar medium, sculpted by powerful stellar
Since humanity first accessed space, thousands of satellites and objects have been launched into low Earth orbit (LEO) for critical missions. The growing density of these objects heightens collision risks, generating debris that exponentially increases further collisions—a chain reaction known as
In the Standard Model of particle physics, elementary particles adhere to key symmetries: translations, rotations, and parity (P symmetry). Among the four fundamental interactions, only the weak force violates P symmetry. Mirror particles—hypothetical counterparts to known particles—could restore th
The universes remarkable order defies the relentless march of thermodynamic entropy, puzzling cosmologists for decades. Ludwig Boltzmann proposed that such complexity arises from rare quantum fluctuations. Lesser fluctuations could spawn self-aware structures known as Boltzmann brains—isolated obser
As space exploration advances, preventing interplanetary contamination has become a critical priority for scientists and space agencies. Protocols have been developed to ensure spacecraft—whether probes or crewed vehicles—do not transfer Earth microbes to other worlds or bring alien biology back hom
Astrolinguistics, also known as xenolinguistics or exolinguistics, is a specialized branch of linguistics focused on developing models for non-human, extraterrestrial languages in anticipation of first contact with an intelligent alien civilization. Though hypothetical today, this field drives rigor
Human ambitions for space colonization extend far beyond the Apollo era. While no crewed deep-space missions have occurred since, projects targeting the Moon and Mars are advancing. Forward-thinking scientists are now exploring solutions for journeys spanning thousands of years to distant star sys
Quantum vacuum fluctuations, driven by Heisenbergs uncertainty principle, create a dynamic bubbling environment that some physicists believe could bend light rays, potentially producing gravitational microlensing effects.Since the advent of quantum mechanics through the pioneering work of Heisenberg
