Tonight, I'm going to talk about the black hole at the center of our galaxy, because according to scientists, this black hole seems to be more and more hungry.


Vasudev and Maher must be wondering what a black hole is. What does it look like?
Maybe some of you are thinking the photo below represents the black hole at the center of the universe.


Actually, the black hole of the universe looks like this:


This is a hearty meal that Sagittarius A, the black hole in the center of our Milky Way, has begun. UCLA researchers are struggling to find an explanation for this "appetite".
Their analysis is based on more than 13,000 observations of the black hole, made over 16 years. Some of the most recent ones would be "unprecedented".

A hole not so black.
Andrea Ghez, professor of physics and astronomy at UCLA (University of California - Los Angeles), recalls the results with amazement: "We have never seen anything like since we studied this hole. In general, it's a pretty quiet black hole. We do not know what induces such a feast.

The extent of this "feast" seems considerable indeed. Since 2003, astronomers have completed more than 13,000 observations of the 133-hole black hole using two Chilean and Hawaiian telescopes. On May 13, they realized that the area close to the point of no return (the area from which matter can not escape once entered) was twice as bright as the brightest event ever observed. However, this brightness corresponds in fact to the radiation of gases and matter swallowed by the black hole.

This year, more observations were made: big changes, described as "unprecedented" by Andrea Ghez, were also observed on these occasions. On one of the four nights of observation between April and May 2019, Tuan Do, one of the authors of the study, said: "In the first observations I made that night, Sagittarius A was so bright that I thought I confused it with the star S0-2. But it soon became clear that the source was to be the black hole.

Looking for explanations.
The star S0-2 is one of the hypotheses raised to explain the more intense activity of the black hole. Indeed, this star which was particularly close to Sagittarius A in the summer of 2018, could have released a large amount of gas, which would have reached the point of no return this year, creating a strong activity in the surrounding area. .

The high brightness, indicates, as we mentioned before, gas and dust falling into the black hole. It raises questions among researchers: is it an isolated event or a real increase in black hole activity? For Mark Morris, also professor of physics and astronomy at UCLA, and co-author of the study, "the big question is whether the black hole enters a new period - for example if the gas rate falling into the black hole increased for a prolonged period - or if we simply witnessed the fireworks from some unusual gas blocks. "

In any case, the black hole, which is some 26 000 light years from Earth, poses no danger to it. Nevertheless, the team continues its observations of the phenomenon, seeking to learn more: "We want to know why this supermassive black hole becomes brighter, and how brighter it becomes." A paradox for a black hole.

Tonight, I'm going to hold a conference about the arrest of Dupont De Ligonnès.


Xavier Dupont de Ligonnès, a Frenchman who is suspected to have killed his entire family in 2011 and has been on the run since, was arrested in Glasgow on Friday, AFP reported, citing police sources.
His family was discovered buried in the garden of their family home in Nantes.
Dupont de Ligonnès had disembarked from a flight from Roissy-Charles de Gaulle airport, near Paris, AFP reported.
"On Friday, 11 October 2019, a man was arrested at Glasgow Airport and remains in police custody in connection with a European Arrest Warrant issued by the French Authorities", a Police Scotland spokeswoman told Euronews.

He was travelling under a false name, but his fingerprints betrayed him. He opposed 'no resistance' to his arrest, according to French newspaper Le Parisien, which broke the news.
Dupont de Ligonnès had disappeared before his family's bodies were found, and the murders had never been solved.
Police found a message he had sent in 2010 in which he had said he wanted to kill his family.

According to the AFP quoting a source close to the case, Dupont de Ligonnès travelled on a French passport that was stolen in 2014, and had "probably spent a part of his time on the run in the UK".
Before the murders, Dupont de Ligonnès had told neighbours and his children's schools that he was a secret agent and that the family was leaving to join a witness protection scheme.

He was last seen in April 2011, appearing on the 14th on a CCTV video as he withdrew money, and on the 15th as he left a hotel. His wife and children's bodies were discovered six days later.

His arrest followed an "anonymous denunciation", AFP reported. Le Parisien reported that he had been living in Scotland for some time.

It turned out that the man arrested at Glasgow Airport is not Xavier Dupont de Ligonnès.

French and Scottish investigators today ruled that fingerprints of the man detained in Glasgow yesterday do not match those of missing suspect Dupont.
It comes after sources in Paris claimed the businessman allegedly arrived at Glasgow International Airport from Charles de Gaulle Airport in Paris.

Dupont, a devout catholic, has been actively sought by police since his disappearance, was subject to an Interpol red notice and has been “sighted” many times over the years.

Today, in La Défense, anti-globalization activists wanted to put Total, Amazon and BNP Paribas out of service.

Forty activists covered the headquarters of several multinationals on Saturday to denounce their role in climate change.
On Saturday, October 12th, at 9:00, about 40 activists from Attac redecorated Total's headquarters in La Défense with banners, also covering the black gouache windows with fire extinguishers and affixing a large poster. on the glass facade, on which one could read: "Danger: Total, Out of service. Harmful for you and the planet. Dickens Kamugisha was also present, the executive director of the NGO Afiego who, with Friends of the Earth France, is preparing to sue Total for its "mega-petroleum" project in Uganda.
