The telescope will join the worldwide effort.

NASA’s James Webb Space Telescope (JWST) successfully launched on Saturday, and it will soon be ready to reveal parts of the universe that have never been seen before including a very large, but very broody, cosmic object at the center of the galaxy.

JWST will be joining in the ongoing, worldwide efforts to observe Sagittarius A*, the supermassive black hole at the center of the Milky Way. This elusive beast has been inferred from its gravitational effects, but imaging the black hole itself has proven elusive.

In April 2019, a group of more than 200 astronomers from all over the world unveiled the very first image of a black hole. Using the Event Horizon Telescope (EHT), an array of radio telescopes imaged the black hole at the center of the galaxy Messier 87 (M87). The EHT team compiled the image from eight telescopes on five continents working over an observing period of seven days.

The largest catalog of gravitational wave events ever assembled has been released by an international collaboration that includes Penn State researchers. Gravitational waves are ripples in space time produced as aftershocks of huge astronomical events, such as the collision of two black holes. Using a global network of detectors, the research team identified 35 gravitational wave events, bringing the total number of observed events to 90 since detection efforts began in 2015.

The new gravitational wave events were observed between November 2019 and March 2020, using three international detectors: The two Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale physics experiment and observatory supported by the National Science Foundation and operated by Caltech and MIT. It’s designed to detect cosmic gravitational waves and to develop gravitational-wave observations as an astronomical tool. It’s multi-kilometer-scale gravitational wave detectors use laser interferometry to measure the minute ripples in space-time caused by passing gravitational waves. It consists of two widely separated interferometers within the United States—one in Hanford, Washington and the other in Livingston, Louisiana.

Did you watch the James Webb Space Telescope launch? If you did–and you stayed with the broadcast beyond the successful launch–you will have seen some dramatic images of it separating from the Ariane 5 launch vehicle and beginning its one million miles journey.

That key moment occurred when Webb was 75 miles/120 kilometers above the Earth, with Webb almost immediately unfolding its solar array to give it power. The mission was live!

The first of three mid-course correction burns was made 12 hours and 30 minutes after launch, firing Webb’s thrusters to manoeuvre the spacecraft on a trajectory toward its destination.

A joint effort between NASA, ESA (European Space Agency) and the CSA (Canadian Space Agency), Webb is the most advanced space telescope yet and is expected to begin a new era in cosmology.

Webb will now begin a month-long journey to orbit the second Lagrange point (L2), a point in space where it can follow Earth in orbit of the Sun, but in the direction away from the Sun.

Astronomers have produced the most comprehensive image of radio emission from the nearest actively feeding supermassive black hole to Earth.

The emission is powered by a central black hole in the galaxy Centaurus A, about 12 million light years away.

As the black hole feeds on in-falling gas, it ejects material at near light-speed, causing ‘radio bubbles’ to grow over hundreds of millions of years.

“PARADOX LOST: The Public Edition, by Marshall Barnes,” Oct 6, 2014.

This book is by internationally noted research and development engineer, Marshall Barnes, and is based on his special report for select members of the United States Congress on the coming reality of time travel, which is now here on the particle level. The only authoritative book on the subject of time travel, it scientifically answers all the issues around the topic, proves why paradoxes are impossible and why the world’s physicists have been so wrong about time travel for so long. Includes definitive analysis of errors by Stephen Hawking, Kip Thorne, Paul Davies, Tim Maudlin, among others. Answers Kurt Godel’s famous question of how can a past that hasn’t passed yet, be the past, and many other issues left unanswered by all other sources.

Among outstanding features, it details Marshall’s creation of the Verdrehung Fan™, the first time machine in the world, that is sending signals through traversable micro wormholes, as speculated could be possible in New Scientist magazine, May 20th, 2014. The Einstein related physics from which it works and how Marshall used it to defeat world famous Ronald Mallett in the race to build a time machine, is revealed as well as why Mallett is far less than the media has made him seem.

Easy to read but rich in detail, this book will be a challenge for scientist and non-scientist alike, with preconceived notions about the subject, as all cliches are dismantled and discarded, revealing stunning, hidden truths that are reached without ever taking a step off the path of known physics. This is the book for those wanting definitive answers backed by definitive proofs and calculations, without dealing with the heavy mathematics.

Look past the details of a wonky discovery by a group of California scientists — that a quantum state is now observable with the human eye — and consider its implications: Time travel may be feasible. Doc Brown would be proud.

The strange discovery by quantum physicists at the University of California Santa Barbara means that an object you can see in front of you may exist simultaneously in a parallel universe — a multi-state condition that has scientists theorizing that traveling through time may be much more than just the plaything of science fiction writers.

And it’s all because of a tiny bit of metal — a “paddle” about the width of a human hair, an item that is incredibly small but still something you can see with the naked eye.

It’s probably in this weird particle.

In a recent study, scientists say they can explain dark matter by positing a particle that links to a fifth dimension.

While the “warped extra dimension” (WED) is a trademark of a popular physics model first introduced in 1999, this research, published in The European Physical Journal C, is the first to cohesively use the theory to explain the long-lasting dark matter problem within particle physics.

Watch the launch of the James Webb Space Telescope—the most powerful space telescope ever made. This mission is scheduled to lift off at 7:20 a.m. EST (12:20 UTC), Dec. 25, 2021, aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana.

With revolutionary technology, Webb will observe a part of space and time never seen before, providing a wealth of amazing views into an era when the very first stars and galaxies formed–over 13.5 billion years ago.

It can explore our own solar system’s residents with exquisite new detail and study the atmospheres of distant worlds. From new forming stars to devouring black holes, Webb will reveal all this and more! It’s the world’s largest and most powerful space telescope ever built.

Webb is an international collaboration between NASA, ESA (European Space Agency), and CSA (Canadian Space Agency). Thousands of engineers and hundreds of scientists worked to make Webb a reality, along with over 300 universities, organizations, and companies from 29 U.S. states and 14 countries!

Ready to #UnfoldTheUniverse? The greatest origin story of all unfurls soon.
