"The Black Hole Paradox" --New Theory Says Soon After Big Bang, Black Holes Lit Up the Universe
Soon after the Big Bang, the universe went completely dark. The intense, seminal event that created the cosmos churned up so much hot, thick gas that light was completely trapped. Much later—perhaps a...
New Scientific Study Suggests Advanced Alien civilizations could have existed Before the Big Bang
Professor Roger Penrose from the University of Oxford (UK) and Vaha Gurzadian from the Center for Cosmology and Astrophysics, Alikhanian National Laboratory and Yerevan State University, Yerevan, Arme...
Ancient and Young Water Worlds of the Cosmos --"NASA Pinpoints Water Vapor Around a Newly Forming Star"
A team of scientists using the Stratospheric Observatory for Infrared Astronomy (SOFIA) has pinpointed the amount and location of water vapor around a newly forming star with groundbreaking precision.
Neutral Result Charges Up Antimatter Research
Scientists of the international ALPHA Collaboration have once again pushed the boundaries of antimatter research with their latest breakthrough studying the properties of antihydrogen. Published today...
Finally Some Answers On Dark Energy, The Mysterious Master Of The Universe
The world's fourth-largest optical telescope has a new experiment coming online. Unless you’re an astrophysicist, you probably don’t sit around thinking about dark energy all that often. That's unders...
Hubble Spots Mother Lode Of 250 Ancient Tiny Galaxies
Scientists are getting a peek into the early days after the big bang thanks to Hubble's discovery of a large collection of dwarf galaxies. The Hubble Space Telescope has been in operation since 1990 a...
Latest Experiment At Large Hadron Collider Reports First Results
After a two-year hiatus, the Large Hadron Collider, the largest and most powerful particle accelerator in the world, began its second run of experiments in June, smashing together subatomic particles ...
New 'Stealth Dark Matter' Theory May Explain Mystery Of The Universe's Missing Mass
Lawrence Livermore National Laboratory (LLNL) scientists have come up with a new theory that may identify why dark matter has evaded direct detection in Earth-based experiments. A group of national pa...
Farthest Galaxy Detected
Caltech researchers have reported the detection of the farthest object yet, galaxy EGS8p7. At more than 13.2 billion years old, it provides a fascinating glimpse of the very early universe, just 600,0...
Tiny Drops Of Early Universe 'Perfect' Fluid
First results from collisions of three-particle ions with gold nuclei reveal clear-cut evidence of primordial soup's signature particle flow. The Relativistic Heavy Ion Collider (RHIC), a particle col...
About 30 Percent Of Stars In The Milky Way Moved From Original Orbits
Scientists have discovered that throughout the Milky Way, stars change orbits and migrate over time. A new map of the galaxy shows changes and stellar migration patterns, the first evidence derived by...
The Case For Spectral Distortions In The Cosmic Microwave Background
Half a century ago, astronomers got their first look at the infant universe: a haze of soft light that suffused the entire sky. This cosmic microwave background (CMB) radiation seemed to indicate that...
ALMA’s Most Detailed View Of Star Formation In Distant Universe
The Atacama Large Millimetre/submillimetre Array’s Long Baseline Campaign has produced some amazing observations, and gathered unprecedentedly detailed information about the inhabitants of the near an...
New Record! Astronomers Nail Down Distance To The Earliest Galaxy Yet
A team of astronomers peering deep into the heavens has discovered the earliest, most distant galaxy yet, spotted a record-breaking 670 million years from the big bang. The findings, described in Astr...
Big Bang
The Big Bang theory is the prevailing cosmological model for the earliest known periods of the universe and its subsequent large-scale evolution. It states that the Universe was in a very high density...

Star formation
Star formation is the process by which dense regions within molecular clouds in interstellar space, sometimes referred to as "stellar nurseries" or "star-forming regions", collapse to form stars. As a...

Large-scale structure of the cosmos
The observable universe consists of the galaxies and other matter that can, in principle, be observed from Earth at the present time because light and other signals from these objects has had time to ...

Ultimate fate of the universe
The ultimate fate of the Universe is a topic in physical cosmology. Many possible fates are predicted by rival scientific hypotheses, including futures of both finite and infinite duration.Once the no...

Future of an expanding universe
Observations suggest that the expansion of the universe will continue forever. If so, the Universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future...
Big Crunch
In physical cosmology, the Big Crunch is one possible scenario for the ultimate fate of the universe, in which the metric expansion of space eventually reverses and the Universe recollapses, ultimatel...

False vacuum
In quantum field theory, a false vacuum is a metastable sector of space that appears to be a perturbative vacuum, but is unstable due to instanton effects that may tunnel to a lower energy state. This...
Heat death of the universe
The heat death of the Universe is a historically suggested ultimate fate of the universe in which the Universe has diminished to a state of no thermodynamic free energy and therefore can no longer sus...
