A 13.8 billions years old explosion live now, on your TV!We’re all aware of the interference we used to see on old analogue televisions when there was no signal. A constellation of black and white dots moving...

Nhà vật lý học lý thuyết William Detmold đã giải mã các bí ẩn về hạt quark, gluon, cũng như các “tương tác mạnh” giữa những hạt này ở mức độ hạ nguyên tử. Các hạt...

For nearly as long as there has been radio, there have been antennas trained on the sky, looking at the universe in a different light than traditional astronomy. Radio astronomers have used their sensitive equipment to...

Our entire cosmic history is theoretically well-understood, but only because we understand the theory of gravitation that underlies it, and because we know the Universe’s present expansion rate and energy composition....

Our Universe, from the hot Big Bang until the present day, underwent a huge amount of growth and evolution, and continues to do so. Although we have a large amount of evidence for dark matter, it doesn’t really make...

An illustration of our cosmic history, from the Big Bang until the present, within the context of the expanding Universe. We cannot be certain, despite what many have contended, that the Universe began from a...

In this article, I’ll show you how to create a simple Big-Bang simulation with JavaScript.Big-BangCheck the video below to see the Big-Bang in action!https://medium.com/media/64d1e1f8291f4093277c7748d4064c7e/hrefAre...

Standard candles (L) and standard rulers (R) are two different techniques astronomers use to measure the expansion of space at various times/distances in the past. Based on how quantities like luminosity or angular size...

This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. The ageing star, catalogued as HD 140283, lies over 190 light-years away. The NASA/ESA Hubble Space Telescope was used to...

In a hypertorus model of the Universe, motion in a straight line will return you to your original location. If time is like a torus, it may be cyclical in nature, rather than having always existed or coming into...

This large, fuzzy-looking galaxy is so diffuse that astronomers call it a “see-through” galaxy because they can clearly see distant galaxies behind it. The ghostly object, catalogued as NGC 1052-DF2, doesn’t have...

Astronomers have discovered an ancient Population II star with very little metal -- but a specific spike in zinc that can only be explained by an asymmetrical supernova explosion. The post The Universe’s First...

Our entire cosmic history is theoretically well-understood, but only qualitatively. It’s by observationally confirming and revealing various stages in our Universe’s past that must have occurred, like when the first...

Scientists have long suspected that helium hydride was the first molecule in the universe, but no one has ever detected it in space until now. NASA researchers have spotted helium hydride many light years away in a...

In the earliest stages of the hot, dense, expanding Universe, a whole slew of particles and antiparticles were created. As the Universe expands and cools, an incredible amount of evolution happens, but the neutrinos...

When we imagine our ideal product launch we picture attention, applause and armies of customers beating a path to our door. Successful companies hardly ever launch with a big bang. Most hits begin with the slow and...

In deciphering the cosmic puzzle of what the nature of dark energy is, we’re going to better learn the fate of the Universe. Whether dark energy changes in strength or sign is key to knowing whether we’ll end in a...

When the very first stars form in the Universe, they form out of hydrogen and helium alone. But when that first generation dies, it can give rise to a second generation that’s far more complex, intricate, and diverse....

The leftover glow from the Big Bang, the CMB, isn’t uniform, but has tiny imperfections and temperature fluctuations on the scale of a few hundred microkelvin. While this plays a big role at late times, after...

An illustration of the first stars turning on in the Universe. Without metals to cool down the stars, only the largest clumps within a large-mass cloud can become stars. (NASA)Shortly after the Big Bang, the Universe...
