Larry Silverberg and his research partner Jeffrey Eischen From North Carolina State University have proposed a surprising new model of physics that could entirely rewrite the way we have studied physics so far.

Have you ever wonder what is the universe made of? If you want to find the answer in syllabus books then it says the universe is made of energy and matter. If you ask the same question to a scientist then he will say it's dark stuff (Dark energy & Dark matter) then if you ask him what is dark matter? then his reply is probably is it's a riddle for science to solve. We are going to tell you about the mystery of dark matter and how scientists of LHC (Large Hadron Collider) gonna solve this mystery.

Astronomers are studying black holes that could have formed in the early universe, before stars and galaxies were born. Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies

On December 3, humanity suddenly had information at its fingertips that people have wanted for, well, forever: the precise distances to the stars. “You type in the name of a star or its position, and in less than a second you will have the answer,” Barry Madore, a cosmologist at the University of Chicago and Carnegie Observatories, said on a Zoom call last week. “I mean …” He trailed off.

Visiting comets can serve as markers in historical timelines. A team of Japanese researchers used one to confirm the death of an Empress.

Many good stories begin with this magical phrase, but have you ever thought that "what is the story of time?" Does time exist? We always say time can be spent, time is money, we waste time, we are trying to save time, but what do we really know about the time? Is time an illusion? According to physicist Brian Greene, "all the time exist at once in spacetime"

Astronomers have discovered a cold brown dwarf – otherwise known as a “super planet” – for the first time using a radio telescope. Brown dwarfs are vast, sized between 15 and 75 times the mass of Jupiter, and have gaseous atmospheres similar to some of the planets in our solar system. They are also often known as “failed stars” because of the way that they shine.

Astrophysicists consider that around 40% of the ordinary matter that makes up stars, planets and galaxies remains undetected, concealed in the form of a hot gas in the complexe cosmic web. Today, scientists at the Institut d’Astrophysique Spatiale (CNRS/Université Paris-Saclay) may have detected, for the first time, this hidden matter through an innovative statistical analysis of 20-year-old data. Their findings are published on November 6, 2020 in Astronomy & Astrophysics.

Astronomers observed 39 cosmic events that released gravitational waves over a 6-month period in 2019 — a rate of more than one per week. The bounty, described in a series of papers published on 28 October, demonstrates how observatories that detect these ripples — usually created by the merging of two black holes — have dramatically increased their sensitivity since the first identification was made in 2015.

A team of astronomers from the University of Hawaiʻi at Mānoa’s Institute for Astronomy (IfA) has produced the most comprehensive astronomical imaging catalog of stars, galaxies, and quasars ever created with help from an artificially intelligent neural network.

The Hubble Space Telescope got a rare look at one of the most awesome light shows in the universe, catching a supernova that outshone every star in its galaxy.

Aided by a trick of gravity, astronomers have found a normal galaxy. Big deal, right? The thing is, where they found it is not normal: The light we see from it left the galaxy 12.4 billion years ago, meaning we’re seeing it as it was when the Universe itself was only 1.4 billion years old! That’s what makes this so weird. A normal galaxy has no business being there when the cosmos was so young. But yet, there it sits.

National Aeronautics and Space Administration (Nasa) has released some stunning and phenomenal images of the universe — galaxies, supernova remnants, stars, planetary nebulas processed by its ‘Chandra X-Ray Observatory’ — the world’s most powerful x-ray telescope.

Scientists have spotted an active galaxy far, far away — and it looks like it could join Darth Vader's fleet. Located 500 million light-years away in the Cassiopeia constellation, Galaxy TXS 0128+554 bears a striking resemblance to the iconic aircraft from Star Wars. According to a paper published Tuesday in The Astrophysical Journal, the galaxy is active, meaning all of its stars are not capable of providing the amount of light emitted by the galaxy on their own.

Astronomers have determined the cause of the dramatic dimming observed last year and earlier this year of one of the brightest stars in the night sky, a colossus called Betelgeuse that appears to be on its way toward a violent death. Based on Hubble Space Telescope observations, scientists said they believe Betelgeuse ejected a huge hot, dense cloud of material into space that cooled to form dust, shielding the star’s light and making it appear dimmer from the perspective of viewers on Earth.

'It's like saying the word 'trillion' almost a hundred times.'

Thirty thousand years ago, a dead star on the other side of the Milky Way belched out a powerful mixture of radio and X-ray energy. On April 28, 2020, that belch swept over Earth, triggering alarms at observatories around the world. The signal was there and gone in half a second, but that's all scientists needed to confirm they had detected something remarkable: the first ever "fast radio burst" (FRB) to emanate from a known star within the Milky Way, according to a study published July 27 in The Astrophysical Journal Letters.

ESA’s Integral helps unravel origin of Fast Radio BurstsA global collaboration of telescopes including ESA’s Integral high-energy space observatory has detected a unique mix of radiation bursting from a dead star in our galaxy — something that has never been seen before in this type of star, and may solve a long-standing cosmic mystery. 

In 1969, the American astronomer Vera Rubin puzzled over her observations of the sprawling Andromeda Galaxy, the Milky Way’s biggest neighbour. As she mapped out the rotating spiral arms of stars through spectra carefully measured at the Kitt Peak National Observatory and the Lowell Observatory, both in Arizona, she noticed something strange: the stars in the galaxy’s outskirts seemed to be orbiting far too fast. So fast that she’d expect them to escape Andromeda and fling out into the heavens beyond. Yet the whirling stars stayed in place.
