First image of black hole at the heart of our galaxy

Published

Astronomers from Event Horizon Telescope (EHT) Collaboration have unveiled an image of a supermassive black hole at the centre of our own Milky Way galaxy

Pictured for the very first time, the gargantuan black hole that lives at the centre of our galaxy provides valuable insight into the workings of such giants, which are thought to exist at the centre of most galaxies.

Scientists had previously seen stars orbiting around a massive, invisible, and compact object, resembling a black hole and this image provides the first direct visual evidence of it.

At an approximate distance of 27,000 light years from Earth, Sagittarius A* (Sgr A*, pronounced “sadge-ay-star”) appears to us to be the same size in the sky as a donut on the moon.

To image it, the global research team created the powerful EHT, which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope.

Although it is not possible to see the black hole itself, as it is completely dark, the glowing gas around it reveals a dark central region (called a “shadow”) surrounded by a bright ring-like structure.

The new view captures light bent by the powerful gravity of the black hole, which is four million times more massive than the Sun.

“We were stunned by how well the size of the ring agreed with predictions from Einstein’s Theory of General Relativity,” says EHT Project Scientist Geoffrey Bower from the Institute of Astronomy and Astrophysics, Academia Sinica, Taipei.

“These unprecedented observations have greatly improved our understanding of what happens at the very centre of our galaxy, and offer new insights on how these giant black holes interact with their surroundings.”

The EHT observed Sgr A* on multiple nights, collecting data for many hours in a row, similar to using a long exposure time on a camera.

The breakthrough follows the EHT 2019 collaboration’s release of the first image of a black hole called M87*, at the centre of the more distant Messier 87 galaxy.

Rate cuts ahead? US stocks bounce as inflation cools

Published

on

Investor sentiment is improving as fresh data out of the US and Australia shifts expectations for central bank action.

Stronger-than-expected labour market figures in Australia have raised questions about whether the Reserve Bank will move ahead with a rate cut next week. While the RBA has signalled it is watching data closely, the resilience in employment may force a delay.

Meanwhile, in the US, softer inflation data has lifted hopes that the Federal Reserve could cut rates later this year. That news helped spark a sharp turnaround in US equities, with the so-called “sell America” trade now unwinding as buyers return to Wall Street.

President Donald Trump’s four-day Middle East tour during his second term has sparked global attention, locking in a monumental $600 billion investment from Saudi Arabia. From AI to defence, space to energy—this economic pact is reshaping U.S. foreign policy.

In an unprecedented move, Trump also lifted long-standing U.S. sanctions on Syria after meeting its new president, raising eyebrows among traditional allies.

Ticker News anchor Veronica Dudo speaks with Erbil “Bill” Gunasti, former Turkish PM Press Officer and Republican strategist, to break down the implications for national security, global diplomacy, and the path to peace in Ukraine.

Trump’s AI deals raise concerns over China ties

Trump’s AI deals in the Middle East spark division over national security risks and concerns over China ties.

In Short:
Trump’s AI deals with Saudi Arabia and the UAE are causing internal conflicts in his administration over US national security. Officials are concerned that American technology supplied to the Gulf could ultimately benefit China, leading to calls for enhanced legal protections.

President Donald Trump’s recent AI deals in Saudi Arabia and the UAE are causing internal conflicts within his administration.

Concerns are rising among officials, particularly China hawks, about the implications for US national security and economic interests.

Agreements include shipments of vast quantities of semiconductors from Nvidia and AMD to the Gulf states, prompting fears that American technology could ultimately benefit China, given the region’s ties with Beijing.

While the accords include clauses to limit Chinese access to the chips, some officials argue that further legal protections are necessary.

Critics, including Vice President JD Vance, have suggested that maintaining US dominance in AI is crucial, and shipping chips abroad might undermine that goal.

Supporters of the deals, including AI Adviser David Sacks, argue the need for American technology in the Gulf to deter reliance on Chinese alternatives.

Despite this, internal discussions are underway to potentially slow down or reassess the agreements due to ongoing national security concerns.

Conversations have also included proposals for a significant chip manufacturing facility in the UAE, which many officials deem risky due to China’s influence.

Additionally, worries persist about G42, an AI firm in Abu Dhabi, which has historical ties to Huawei.

The agreements with Gulf countries promise to enhance their technological capabilities while necessitating careful oversight to address US security priorities.
