Today, Scientists Will Make an Announcement on The Milky Way on Thursday!

Scientists who previously revealed the world’s first photograph of a black hole are due to make another historic statement this week about our galaxy, the Milky Way, including the supermassive black hole Sagittarius A*. According to a release, the US National Science Foundation (NSF) will host a news conference on Thursday with the Event Horizon Telescope Collaboration to unveil “groundbreaking discoveries regarding the core of our galaxy.” One of the most significant space activities will be aired live on the National Science Foundation’s Facebook page.

The meeting will be co-hosted by the National Science Foundation of the United States, the European Southern Observatory, the Joint ALMA Observatory, and other funding agencies and institutions.
Karen Marrongelle, NSF’s Chief Operating Officer, will give the keynote speech. At the occasion, a panel of researchers from the Event Horizon Telescope, or EHT, will discuss their results and answer media questions. According to a release from the National Science Foundation (NSF) on May 10, the news is connected to the finding made by the Event Horizon Telescope. Scientists are expected to show an image of the Milky Way’s Supermassive Black Hole captured by the Event Horizon Telescope.

The EHT is a global network of radio telescopes dedicated to studying and observing black holes.

EHT gave a black hole image.

In April 2019, the international scientific group EHT released the first photograph of the Messier 87 black hole, which was discovered in the neighboring radio galaxy Centaurus A. The photograph showed the bright disk that encircled the M87 galaxy’s supermassive black hole (SMBH). The Event Horizon Telescope or EHT was launched in 2020 by the Smithsonian Astrophysical Observatory in collaboration with the National Society of Black Physicists.

According to the National Science Foundation, May is “Black Holes Week,” during which the scientific community explores black holes, which have long piqued the public’s interest but have proven difficult to detect. Scientists now know a lot about these things and how they arise, and they can even observe how they interact with their environment, thanks to a mix of theory and observation. The first picture of a black hole was unveiled by the worldwide Event Horizon Telescope a century after Albert Einstein suggested the pioneering concepts in his theory of general relativity.

The European Southern Observatory (ESO) and EHT researchers are anticipated to release the findings of their investigation of the SMBH in our Milky Way galaxy on May 12. On Thursday, May 12th, at 03:00 pm CEST, a news conference will be held (08:00 EDT; 05:00 PDT) The event will be live-streamed from ESO Headquarters in Munich, Germany.

The Nearest Radio Galaxy’s Dark Heart Is Found by EHT.

Centaurus A shines brightly in the night sky at radio frequencies. Centaurus A has been widely examined over the whole electromagnetic spectrum by a number of radio, infrared, optical, X-ray, and gamma-ray observatories since it was detected as one of the earliest known extragalactic radio sources in 1949. A black hole with a mass of 55 million suns sits in the core of Centaurus A, almost halfway between the mass scales of the Messier 87 black hole (6.5 billion suns) and the one at the heart of our own galaxy (about four million suns).

Data from the 2017 EHT observations were examined in new research published in Nature Astronomy to create an unparalleled picture of Centaurus A. “We can witness and investigate an extragalactic radio jet on scales smaller than the distance light travels in a day for the first time.” “We get to watch firsthand how a monstrously huge jet-propelled by a supermassive black hole is formed,” astronomer Michael Janssen explains.

The Centaurus A jet is photographed at a tenfold greater frequency and sixteen times better resolution than all prior high-resolution images. We can now relate the immense scales of the source, which are as large as 16 times the angular diameter of the Moon in the sky, to their origin near the black hole, which is just the width of an apple on the Moon when projected on the sky, thanks to the EHT’s resolving capacity.

Jets: What You Should Know?

Gas and dust are drawn to supermassive black holes at the centers of galaxies like Centaurus A. The galaxy is thought to become ‘active’ when this process releases large quantities of energy. The majority of matter near the black hole’s edge is swallowed. Jets, one of the most intriguing and explosive aspects of galaxies, are produced when some of the surrounding particles escape seconds before being captured and are flung far out into space.

To get a better understanding of this process, astronomers have used many models of how matter behaves around a black hole. However, scientists are still unsure how jets are produced from the galaxy’s core and how they may stretch across scales greater than their host galaxies without scattering. The EHT is tasked with solving the puzzle.

 

The jet released by Centaurus A appears brighter at the margins than in the center, according to the latest photograph. This phenomenon has been witnessed previously in other jets, but never in such a dramatic manner chevalier cheval chevalier chevalier chevalier chevalier chevalier chevalier chevalier “We can now rule out theoretical jet models that can’t replicate this edge-brightening.” “It’s a stunning characteristic that will help us better comprehend black hole jets,” says Matthias Kadler, TANAMI‘s leader and astrophysics professor at the University of Würzburg in Germany.

I write picture books, for middle grade, and young adults, some of which have won prizes, been filmed, or become bestsellers. I've ghostwritten for Pixar and developed teen work for Alloy Entertainment. I think heartfelt writing is the finest. It doesn't have to be personal, but it must be visceral. You want them riveted from the first word, page, or sentence, no matter how painful or unpleasant, and that's my expertise.
