How the Big Bang's Leftover Light Reveals What the Universe Is Made Of
The Cosmic Microwave Background (CMB) is faint microwave radiation filling the sky, the richest source of data about the universe's earliest observable moments. By measuring its temperature variations, scientists have determined the universe's composition, including dark energy, dark matter, and ordinary matter.
What are cosmic microwave background origins and significance?
The universe's faint, omnipresent glow, known as the cosmic microwave background (CMB), represents the earliest light detectable by humanity, originating approximately 380,000 years after the Big...
Nancy Grace Roman Telescope Poised to Reveal Universe Secrets
In 2026, the Nancy Grace Roman Space Telescope will launch with a field of view 200 times larger than Hubble's infrared capability, promising to map vast swathes of the cosmos with comparable image qu
Webb Telescope Spots Little Red Dots That Appear to Be Black Holes
Peering back 1.8 billion years after the Big Bang, the James Webb Space Telescope has revealed a seemingly innocuous 'little red dot' as a candidate for a 'black hole star', according to Universe Toda
Theory: Exoplanets Could Form Near Supermassive Black Holes
Millions of Jupiter-mass planets, dubbed 'dust giants' and 'lava balls,' could emerge tens of parsecs from supermassive black holes, according to Space .
New research confirms universe expansion rate and cosmic acceleration
Just months ago, a whisper of deceleration rippled through the cosmos.
Space telescope satellite generates overwhelming data streams
Every day in 2026, the newly launched SPHEREx telescope downlinks 20 gigabytes of science data, a torrent of information equivalent to hundreds of thousands of digital photos, all captured from galaxi
Entropy Undermines Cyclic Universe Theory
Each subsequent cosmic cycle would be 'dirtier' and longer than the last, a profound challenge for cyclic universe models.
New Data Reveals Universe Cannot Be Cyclic
The universe is expanding so rapidly that even light from distant galaxies will eventually be stretched beyond our observable horizon, making a 'Big Crunch' and subsequent 'Big Bounce' physically impo
New Theory Proposes Universe With No Beginning
What if the universe didn't begin with a bang, but with a bounce – emerging from the collapse of a previous cosmos?
The Big Ring: A 1.3-Billion-Light-Year Structure That Strains the Rules of Cosmology
Astronomers have identified the Big Ring, a colossal ring-shaped structure of galaxies spanning 1.3 billion light-years, which challenges the Cosmological Principle. Its immense size, exceeding theoretical limits, suggests our understanding of the universe's large-scale structure may need rethinking.
