How the universe got its structure

The universe is full of billions of galaxies. Why do we see so much structure in the universe today? A 10-year survey of tens of thousands of galaxies has provided a new approach to answering this fundamental mystery.

The Universe may not look the same in all directions

One of the core assumptions of astronomy is that the universe appears the same in all directions, or it is isotropic. However, a recent study suggests that may not be the case. 

New Study Suggests The Universe Is a Closed Sphere

Years of observational data, cosmological models and physics suggest the Universe is flat. However, a recent study suggests that the Universe is actually curved and closed, like an inflating sphere.

New hints to the mystery of universe's expansion

Astronomers have made a new measurement of how fast the universe is expanding, using an entirely different kind of star than previous endeavors. The revised measurement may lead to a new interpretation of the universe's fundamental properties.

Deepest Image of the Universe Ever Taken

It has taken researchers almost three years to produce this deepest image of the Universe ever taken from space, by recovering a large quantity of ‘lost’ light around the largest galaxies in the iconic Hubble Ultra-Deep Field.

Our universe: An expanding bubble in an extra dimension

Swedish researchers have devised a new model for the Universe, that may solve the enigma of dark energy. They proposes a new structural concept of a universe that rides on an expanding bubble in an additional dimension.

Fossil from the Big Bang discovered

A relic cloud of gas, orphaned after the Big Bang, has been discovered in the distant universe by astronomers using the world's most powerful optical telescope, the W. M. Keck Observatory on Maunakea, Hawaii.

Astonishing New Theory Could Explain Universe’s Missing 95%

UK researcher, Jamie Farnes, suggests both dark energy and matter can be unified into a single substance — a negative-mass ‘dark fluid.’ The theory may also prove right a prediction that Albert Einstein made 100 years ago.

Expanding Universe Mystery Deepens

An important discrepancy in measurements of the universe’s acceleration has theorists wondering whether we’ve gotten something fundamentally wrong in our understanding of the history of the universe.

Some good came out of 2018: Astronomy photos

Each year, the Insight competition reminds us of how amazing our Universe is.

Last of universe's missing ordinary matter

Until now, astrophysicists had only been able to locate about two-thirds of the ordinary matter. In the new research, an international team pinned down the missing third.

Stephen Hawking's final theory about the big bang

The theory, which was submitted for publication before Hawking's death earlier this year, is based on string theory and predicts the universe is finite and far simpler than many current theories about the big bang say.

Hubble data indicate universe growing faster than expected

Lengthy observations by the Hubble Space Telescope indicate the universe is expanding faster than predicted by standard models and that Einstein’s cosmological constant, thought by many to define dark energy, may not be so constant after all.

Astrophysicists have built the most detailed simulation of the Universe ever

The simulation consists of 18 simulations covering various scales - each a cubic mock-up of space up to 1 billion light years wide - tracing the evolution of the Universe from just after the Big Bang into the future.

Scientists discover the existence of 4D, one more invisible 'spatial dimension'

Even though we cannot physically access the 4D world, being aware of its existence will pave the way to future discoveries and a better understanding of our Universe.
