When you peer out into the depths of the cosmos, a mystery lies there, waiting. In a survey of the deep sky, most of the galaxies are seen rotating in the same direction.
When you look around the Universe you live in, it looks like a 3D space, just like the surface of the Earth looks like a 2D space. However, just like the Earth, if you were to look at the Universe as a whole, it could be a more complicated space.
A new measurement confirms what previous - and highly debated - results had shown: The universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics.
Researchers set a new benchmark, capturing the physics of dark and atomic matter with unmatched precision.
Using data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have completed the most precise gravity test ever taken.
The current theoretical model for the composition of the universe is that it’s made of ‘normal matter,’ ‘dark energy’ and ‘dark matter.’ A new study challenges this.
New research suggests that the so-called clumpiness problem, which centers on the unexpectedly even distribution of matter on large scales throughout the Universe, may be a sign that dark matter is composed of hypothetical, ultra-light particles.
A retired cosmological theory should be given a second chance at explaining anomalies in our Universe, according to theoretical physicist Rajendra Gupta from the University of Ottawa in Canada.
Scientists have for the first time observed the early universe running in extreme slow motion, unlocking one of the mysteries of Einstein's expanding universe.
Astronomers have made a discovery that confirms the existence of gravitational waves, which sound like the hum at a large gathering. These ripples in space-time were proposed by Albert Einstein over a century ago.
There could have been two scenarios with the two Big Bangs. The Hot Big Bang, as in the standard picture, creates the hot plasma of visible matter and radiation and the dark matter, however, could have been created in a later, ‘darker’ Big Bang.
One of the most common sources of magnetic fields on large scales comes from the collisions between and within interstellar plasma. This is one of the major sources of magnetic fields for galactic-scale magnetic fields.
According to a new U.S. research it appears that the Universe is actually getting hotter as time goes on. The mean temperature of cosmic gas has increased more than 10 times and reached about 2.2 million K.
A team of U.S. astronomers have created the Pan-STARRS1 Source Types and Redshifts with Machine Learning (PS1-STRM), the world’s largest three-dimensional astronomical catalog.
U.S. scientists have precisely measured the total amount of matter making up the cosmos, concluding that dark energy accounts for 69 % of the total mass-energy budget with normal and dark matter being 31.5 %.
