Dubbed the “unicorn,” the odd object is also among the smallest black holes ever found, and it may help solve an enduring mystery in astrophysics.
Astronomers have captured a breathtaking radio wave image, showing our closest radio active black hole spewing out massive jets of plasma that span more than 16 times the size of the full moon in our sky.
The supermassive black hole in question is located in the center of the galaxy Centaurus A around 12 million light-years away.
The black hole has a jaw-dropping mass of around 55 million Suns but isn’t visible in the image. It would be located within the small empty patch in the center of the two butterfly wing-like lobes.
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.

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.
A new analysis of Event Horizon Telescope data from 2017 brings to light the magnetic fields twisted around the black hole at the core of galaxy M87.
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.
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.
“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.
