James Webb Just Detected A Huge Structure Older Than The Universe!

Posted by in categories: cosmology, education

The big bang is one of the most fascinating topics you can bring up when conversing with scientists and astronomers. This is because the theory talks about how the whole universe started in the first place. However, the event that led to the big bang is one thing that is being argued among scientists today.

For this reason, the James Webb Telescope was called in to make some findings about the big bang. The JWST found something quite alright, but it wasn’t something the scientist had prepared their minds for. What did the James Webb Telescope discover, and in what way would it affect the Big Bang Theory?

A strange burst of radiation from space has left scientists baffled

Posted by in category: cosmology

Astronomers are in a state of bewilderment after they discovered strange blasts of radiation from space. Those blasts, known as gamma-ray bursts (GRBs), seem to come from a black hole that is developing slowly after two stars merged. According to NewScientist, gamma-ray bursts come in two categories: short GRBs and gamma-ray explosions: short GRBs and long GRBs.

Why we’ll never see back to the beginning of the Universe

Posted by in category: cosmology

We thought the Big Bang started it all. Then we realized that something else came before, and it erased everything that existed prior.

U.S. Dept of Energy Breakthrough: Detecting Dark Matter With Quantum Computers

Posted by in categories: computing, cosmology, particle physics, quantum physics

Dark matter makes up about 27% of the matter and energy budget in the universe, but scientists do not know much about it. They do know that it is cold, meaning that the particles that make up dark matter are slow-moving. It is also difficult to detect dark matter directly because it does not interact with light. However, scientists at the U.S. Department of Energy’s Fermi National Accelerator Laboratory (Fermilab) have discovered a way to use quantum computers to look for dark matter.

Aaron Chou, a senior scientist at Fermilab, works on detecting dark matter through quantum science. As part of DOE’s Office of High Energy Physics QuantISED program, he has developed a way to use qubits, the main component of quantum computing.

Performing computation using quantum-mechanical phenomena such as superposition and entanglement.

A hyperactive sunspot to result in solar flares

Posted by in category: cosmology

The effects of solar activity are predicted to reach the Earth’s atmosphere by December 8.

The earth is all set to experience another set of solar flares, which is estimated to reach our atmosphere by December 8. After a relatively calmer period of solar activity, we are about to experience a high-velocity gush of solar winds and minor geomagnetic storms. The intensity of the storm expected is classified as G1, the least intense solar storm.

Images taken of the sun on December 4 by Eduardo Schaberger Poupeau, an astrophotographer, revealed five significant sunspots and two filaments of magnetism facing Earth.

Scientists suggest sending atomic clocks near the Sun to search for dark matter

Posted by in category: cosmology

Ultralight dark matter has wavelike properties that could affect the operation of the clocks.

For decades, scientists have been trying to wrap their heads around the dark matter, which makes up an estimated 85 percent of the mass in the universe. Despite experimental efforts running for decades, researchers have only been able to observe the essence, not quite detect it.

Now, a new study published in Nature Astronomy on December 5 revealed that an atomic clock on-board a spacecraft inside the inner depths of the solar system could search for ultralight dark matter. The latter has wavelike properties that could affect the operation of the clocks.

Remarkable JWST trick lets us “see” dark matter

Posted by in category: cosmology

It’s not only the gravity from galaxies in a cluster that reveal dark matter, but the ejected, intracluster stars actually trace it out.

Latest Webb Results Could Literally Break All Cosmology

Posted by in categories: cosmology, physics

The James Webb Space Telescope has finally made its first dark matter observations, and the results could lead us to new physics. They have questioned our understanding of dark matter and the large-scale structure-formation of the Universe. Dark matter is one of the most mysterious entities in the cosmos. Our best cosmological models show that 27% of the observable Universe is made of dark matter. We can’t see it, but its existence can be inferred because of its effect on surrounding baryonic matter. The true nature of dark matter is still one of the biggest mysteries in cosmology. The most successful cosmological model to date, the lambda cold dark matter or the LCDM model, makes a critical prediction regarding dark matter. It says that cold dark matter played an important role to form the large-scale structures we observe today.

So far, we did not have the technology to test this prediction. But the James Webb Space Telescope opened the windows to the first billion years and the last unexplored era in the history of the Universe. The super-early galaxies discovered by Webb in its Early Release Science program provided an opportunity to test the predictions made by the LCDM model. And when astronomers did that, the results were completely unexpected. So what do these primordial galaxies discovered by Webb tell us? What did Webb find in its first dark matter observations? Finally, and most importantly, how can these results change the course of cosmology?

Astronomers Discover Supermassive Black Hole Pointing Directly at Earth

Posted by in category: cosmology

Earlier this year, scientists discovered that a “jet,” created by a very distant supermassive black hole, sent an accumulation of various space matter rocketing directly toward Earth. Scientists haven’t expressed any need for concern about the jet. However, they are intrigued by the sheer brightness of it and the vast distance between it and Earth.
