Scientists Find Dark Matter From 1.5 Billion Years After The Universe's Beginning

Particles of dark matter keep giving us signals and astronomers also claim to have received something related to dark matter. Dark matter is a puzzle itself. Recently, astronomers have observed the effects of dark matter at the edge of the observable universe, when our universe was only 1.5 billion years old. It neither emits light nor absorbs light, but its gravitational effect does affect light. The clumps of dark matter form the gravitational lensing that is able to deflect or focus light. Astronomers have measured dark matter found in galaxy clusters through this same effect. We can also see this lensing effect in James Webb's deep field images. The light from extremely distant galaxies is distorted by the mass of nearby galaxies, Astronomers can map and calculate the distribution of dark matter in those nearby galaxies using this nature of light. But, recent studies show the galaxies to be so far away that there are actually no more distant galaxies.  Recommended ⬇

Earth is Spinning Faster Than Usual and Had its Shortest Day Ever

Has the Earth's rotation on its axis really accelerated? According to a report in CBS News , June 29 was the fastest day in history on record - 1.59 milliseconds short of the average 24 hours. According to a recent study, the Earth started rotating faster from around 2016 and the average days have now become shorter. However, according to the study's authors, the rotation change is not enough to shorten each day. But its impact has been made clear enough to make the scientific community buzz. But, if this trend continues, then mankind will likely to make some changes in its atomic time. But doing so will not be easy at all, because the tech industry does not want this at all. Have you ever heard about the Y2K bug which is already infamous in cyber world. Historically, the earth has never kept the correct time. Tides coming from oceans to Earth's magma core affect its movement.   According to an article published in The Guardian , our planet has slowed down a bit

Astronomers Captured a Brilliant Afterglow of Violet Star Merger

Astronomers surprised by releasing a mysterious video on Wednesday. This video showed a footage of ever-evolving lime green spots on dark background. Along with this, the second spot is visible which is the brightest neon bulb. What you're seeing is proof that about 20 billion years ago an ultra powerful neutron star collided with a dim star, spitting out an explosive, short-lived gamma ray burst, rippling gravitational waves across the universe and diffusing surrounding space with a potent afterglow. It was a shattering merger that occurred when the universe was just 40% old of its current age, and our remarkable view of this incident is courtesy of the world's largest radio telescope, the Atacama Large Millimeter/Submillimeter Array (ALMA) situated in Chile. ALMA is a combination of 66 radio telescopes that are spread across the Chilean Andes and work together to gather information about the universe. ALMA program chief Wen Fi Fong said in a statement "The af
