Astronomers spot a massive ‘sleeping giant’ black hole less than 2,000 light-years from Earth
mega dark
Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space.

The so-called “sleeping giant,” named Gaia BH3, has a mass that is nearly 33 times that of our sun, and it’s located 1,926 light-years away in the Aquila constellation, making it the second-closest known black hole to Earth. The closest black hole is Gaia BH1, which is located about 1,500 light-years away and has a mass that is nearly 10 times that of our sun.

Astronomers discovered the black hole while combing through observations taken by European Space Agency’s Gaia space telescope for an upcoming data release to the scientific community. The researchers weren’t expecting to find anything, but a peculiar motion — caused by Gaia BH3’s gravitational influence on a nearby companion — caught their eye.

Many “dormant” black holes don’t have a companion close enough to munch on, so they are much more difficult to spot and don’t generate any light. But other stellar black holes siphon material from companion stars, and this exchange of matter releases bright X-rays that can be spotted through telescopes.
The wobbling movement of an old giant star in the Aquila constellation revealed that it was in an orbital dance with a dormant black hole, and it’s the third such dormant black hole spotted by Gaia.

The researchers used the European Southern Observatory’s Very Large Telescope in Chile’s Atacama Desert and other ground-based observatories to confirm the mass of Gaia BH3, and their study has also offered new clues to how such huge black holes came to be. The findings appeared Tuesday in the journal Astronomy & Astrophysics.

“No one was expecting to find a high-mass black hole lurking nearby, undetected so far,” said lead study author Pasquale Panuzzo, an astronomer at the Observatoire de Paris, part of France’s National Centre for Scientific Research, and a Gaia collaboration member, in a statement. “This is the kind of discovery you make once in your research life.”

Former Brazilian soccer player Robinho arrested after failed appeal
обменять btc

Former Brazilian footballer Robson de Souza – also known as Robinho – was arrested by Federal Police on Thursday in Santos, in the Brazilian state of Sao Paulo, his lawyer told CNN affiliate CNN Brasil, as police cars were seen leaving his residence in Santos.

The 40-year-old former AC Milan and Brazil striker faces nine years in prison after being convicted in Italy for gang raping a woman with five other men in 2013 after plying her with alcohol in a Milan nightclub.

Robinho’s arrest comes as Brazil’s Supreme Court (STF) denied his appeal on Thursday to remain out of custody while all judicial appeals against his conviction are exhausted and ordered for the “immediate” start of his prison sentence, according to a statement from the STF.
The footballer’s defense team had appealed to Brazilian authorities to allow Robinho to serve his jail time in Italy, rather than Brazil and to remain free while all appeal proceedings are ongoing, according to the STF decision.

Robinho has always denied the charges.

Following Thursday’s arrest Robinho is expected to face a custody hearing on Friday before being sent to a detention facility to being his prison sentence according to CNN Brasil.

A high-altitude tunnel is latest flashpoint in India-China border tensions
обменник криптовалют

A tunnel constructed high in the mountains of northeastern India has become the latest flashpoint in a simmering border dispute between New Delhi and Beijing.

The Sela Tunnel, inaugurated by Indian Prime Minister Narendra Modi earlier this month, has been hailed in India as a feat of engineering – blasted through the Himalayas at an elevation of some 13,000 feet (3,900 meters) – and a boon for the military, enabling faster, “all-weather” access to a tense de facto border with China.

That’s caught the attention of Beijing, whose long-running dispute with New Delhi over their contested 2,100-mile (3,379-kilometer) border has seen the two nuclear-armed powers clash in recent years.

That includes in 2020 when hand-to-hand fighting between the two sides resulted in the deaths of at least 20 Indian and four Chinese soldiers in Aksai Chin-Ladakh in the western stretches of the border.

And, decades ago, the dispute led to war.

China also claims the Indian state of Arunachal Pradesh, where the tunnel was constructed, as its own, even as the area has long functioned as Indian territory.

Chinese officials in recent days have slammed the tunnel project and Modi’s visit to the state, accusing New Delhi of taking steps to undermine peace along the border.

“We require the Indian side to cease any action that may complicate the boundary question … the Chinese military remains highly vigilant and will resolutely defend national sovereignty and territorial integrity,” a Defense Ministry spokesperson said last week, using the Chinese name “Zangnan” or South Tibet to refer to Arunachal Pradesh.
