Welcome Back To Theory Of Science! The James Webb Space Telescope is the largest, most powerful space telescope ever built. It will allow scientists to look at what our universe was like about 200 million years after the Big Bang. The telescope will be able to capture images of some of the first galaxies ever formed. It will also be able to observe objects in our solar system from Mars outward, look inside dust clouds to see where new stars and planets are forming and examine the atmospheres of planets orbiting other stars. The Webb telescope is as tall as a 3-story building and as long as a tennis court! It is so big that it has to fold origami-style to fit inside the rocket to launch. The telescope will unfold, sunshield first, once in space The James Webb Space Telescope sees the universe in light that is invisible to human eyes. This light is called infrared radiation, and we can feel it as heat. Firefighters use infrared cameras to see and rescue people through the smoke in a fire. The James Webb Space Telescope will use its infrared cameras to see through dust in our universe. Stars and planets form inside those dust clouds, so peeking inside could lead to exciting new discoveries! It will also be able to see objects (like the first galaxies) that are so far away that the expansion of the universe has made their light shift from visible to infrared! in this video, we are looking into James Webb Telescope’s Latest Captures.

What we call laws of physics are often just mathematical descriptions of some part of nature. Ultimate physical laws probably don’t exist and physics is all the better for it, says theoretical physicist Sankar Das Sarma.
And the galaxy from which the GRB came from is also strange. It is young and still forming stars – the opposite of the only other known nearby galaxy that has played host to such an event.
“This event looks unlike anything else we have seen before from a long gamma-ray burst,” said Jillian Rastinejad, from Northwestern University, who led the study. “Its gamma rays resemble those of bursts produced by the collapse of massive stars.
Given that all other confirmed neutron star mergers we have observed have been accompanied by bursts lasting less than two seconds, we had every reason to expect this 50-second GRB was created by the collapse of a massive star. This event represents an exciting paradigm shift for gamma-ray burst astronomy.
“Information,” wrote Arizona State University astrophysicist Paul Davies in an email to The Daily Galaxy, “is a concept that is both abstract and mathematical. It lies at the foundation of both biology and physics.”
Viewing information at the cosmic level, physicist Melvin Vopson at the University of Portsmouth in the UK has estimated in a paper how much information a single elementary particle, like an electron, stores about itself. He then used this calculation to estimate the staggering amount of information contained in the entire observable Universe. Practical experiments can now be used, he suggested, to test and refine these predictions, including research to prove or disprove the hypothesis that information is the fifth state of matter in the universe beyond solid, liquid, gas, and plasma.

Effects from the COVID-19 pandemic and the resulting economic disruption still loom large over businesses around the world.
Digital-native organizations (DNOs) already using cloud infrastructures and mobile apps to conduct business with customers adapted quickly to the new digital normal. However, despite their best efforts, some established enterprises remain stuck in their digital transformations and cloud adoption journeys. Companies that have struggled to adapt face a huge — and perhaps existential — challenge on how to remain relevant in this new digitally-oriented world.
