Researchers have taken deep pictures of two ancient galaxies, weighing them for the first time. The galaxies are estimated to be around 50-300 million years old, with masses similar to our Milky Way's, but were much lighter when they formed.
George Smoot's discovery of miniscule temperature variations in the infant universe revealed a pattern consistent with the Big Bang theory. This finding, supported by subsequent experiments, confirmed the cosmos' origins and provided evidence for gravity's role in shaping the universe's structure.
Researchers used Hubble Space Telescope to explore galaxy formation during first 900 million years after Big Bang. They found a significant increase in bright galaxies around 13 billion years ago, providing evidence for hierarchical theory of galaxy formation.
A new study has found that deuterium, a heavy form of hydrogen, exists in greater amounts than anticipated in the Milky Way galaxy. This discovery could fundamentally alter our understanding of star and galaxy formation.
Scientists using NASA's FUSE satellite discovered more 'heavy' hydrogen in the Milky Way than expected, altering theories about star and galaxy formation. The finding indicates that destruction of deuterium has been occurring at a slower rate than previously thought.
A team of researchers at Penn State has discovered a mathematical description of a contracting universe that existed before the Big Bang, with space-time geometry and gravity exhibiting unique properties. The findings rely on loop quantum gravity theory, which proposes a discrete 'atomic' structure to space-time.
The current science education system fails to convey a comprehensive narrative account of the origins and evolution of the universe, planet, and life. This results in students lacking a robust grasp of the scientific worldview, leading to scientific illiteracy and poor understanding of scientific concepts.
Physicists prove that tiny but ageing neutrinos can be used to test the foundations of quantum theory at unprecedented cosmological time scales. This method is more decisive than observing macroscopic objects.
A team of scientists led by Alan E.E. Rogers successfully detected deuterium using a radio telescope array, a significant breakthrough in understanding the universe's origins. The detection has implications for understanding dark matter and cosmic baryon density.
The team developed statistical techniques to analyze WMAP data, helping confirm the Big Bang theory and offering insights into the universe's shape, composition, and fate. Their approach allows for separation of data information from model assumptions, providing a more accurate understanding of the cosmos.
A study suggests that abandoning livestock can significantly reduce global warming, with animal agriculture emitting 21% of all human-caused carbon dioxide. This shift in diet would have no adverse effects on health and could potentially meet Kyoto treaty targets for reducing emissions.
Duke physicists Berndt Mueller and Steffen A. Bass contribute to the search for a superhot quark-gluon plasma by analyzing experimental data from RHIC collisions. Their work provides evidence that the matter created in these collisions exhibits unique properties, challenging current physical theory.
Researchers dust off dusty shelf by applying Hanbury Brown-Twiss Interferometry to high-energy gold nucleus collisions, reconciling experimental data with theoretical expectations. They found that pions in the plasma have a low mass inside but a higher mass outside, helping create quark-gluon plasma conditions similar to those just aft...
Researchers Sean Carroll and Jennifer Chen suggest infinite entropy, rather than finite, resolves the universe's low entropy, allowing for an eternal cycle of inflation and increasing entropy. This approach resolves a long-standing puzzle in physics, explaining why time flows in only one direction.
Recent study by Yale University's Richard Easther and colleagues proposes that the Cosmic Microwave Background (CMB) may contain evidence for string theory. The CMB is thought to hold a fossilized record of the first moments of time, with subtle fluctuations potentially revealing signs of string theory.
A team of astronomers has discovered 13 distant quasars, providing valuable insights into the early universe. The most ancient quasars are thought to have formed right along with supermassive black holes, suggesting a rapid transition from the cosmic dark ages to the cosmic renaissance.
A team of international astronomers has identified an ancient star in the Milky Way Galaxy, dated to 14-15 billion years ago. The discovery provides direct knowledge of the elemental composition of the universe shortly after the Big Bang, offering insights into the formation of stars and the chemical recipe of the early universe.
University of Washington cosmologist Craig Hogan believes new experiments could shed light on subatomic particles called gravitons, potentially uniting quantum mechanics and relativity. These advancements might also provide clues to the holographic principle, which suggests everything in 3D can be specified by information in 2D.
The Far Ultraviolet Spectroscopic Explorer (FUSE) will test the Big Bang theory and collect comprehensive observations of the Milky Way's star-forming regions. Launched on June 23 from Cape Canaveral Air Station, the three-year mission marks a first for an academic department in managing a satellite.
Magnetic patterns on Mars indicate ancient plate tectonics system, with implications for understanding of the planet's topography. The team found evidence of symmetrical mirror-image stripes, similar to those on Earth, which could be remnants of a long-lost plate tectonics system.
The FUSE Satellite will observe wavelengths of light inaccessible to other telescopes, testing models of chemical evolution and determining the primordial abundance of deuterium. This will help scientists understand the origins of the universe, galaxy evolution, and chemical mixing and distribution.
An Australian-led team of astronomers has discovered a significant number of stray stars, potentially altering our understanding of the universe's composition. These findings suggest that there may be as many stars living in intergalactic space as those within galaxy clusters.
Astronomers believe the Universe has expanded since the big bang about 15 billion years ago, but a new theory proposes that it may have rotated like a merry-go-round for an indefinitely long period. If true, this rotation could have suddenly changed into expansion thanks to a 'vacuum phase transition.'
Researchers have modeled semilocal strings in the universe, which may explain why there is more matter than antimatter. The strings' behavior could also shed light on the formation of galaxies and large-scale structure.
