Astronomers find first-ever star gradually eaten by black hole

Published

Astronomers have found for the first time a sun-like star being gradually eaten in chunks — as large as three times the size of the Earth — by a supermassive black hole located about 520 million light years from our solar system.

The new revelations will allow scientists to understand further the destructive relationship between the enormous deep space objects.

The nearest-to-Earth supermassive black hole Sagittarius A* is located at the centre of the Milky Way galaxy and is four million times bigger than our Sun, according to the research paper published in the journal Nature.

Black holes are massive objects present in nearly the centre of nearly every giant galaxy. It also forms when a giant star dies and collapses under its own weight. These space objects are so powerful that they pull inside everything which enters their event horizon. Not even light can escape from their potent pull.

According to a recent study, astronomers noted that they have identified a supermassive black hole at the centre of a relatively nearby galaxy as its feast is underway eating chunks of the star.

The observation also noted that the size of the consumption is huge as the star passes near the black hole on its elongated oval-shaped obit.

Researchers noted in the study published in the journal Nature Astronomy that the giant star is located at a distance of about 520 million light years from our solar system.

A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). It was observed being plundered by a supermassive black hole at the heart of a spiral-shaped galaxy.

As there are a number of large black holes, this recently discovered is a small one with a mass of a few hundred thousand times larger than the sun.

The data used for the study was from Nasa’s orbiting Neil Gehrels Swift Observatory.

The cosmic prey was observed orbiting the black hole every 20 to 30 days. As it comes to its one end of the orbit, closing into the celestial hunter, it experiences its stellar atmosphere sucked away, or accreted, each time it passes.

The distance is enough to save the whole star shredded. Such an event is called a “repeating partial tidal disruption.”

After the stellar material is pulled into the black hole, the temperature of the matter increases up to around 3.6 million degrees Fahrenheit (2 million degrees Celsius), resulting in an immense amount of X-rays.

Astrophysicist Rob Eyles-Ferris of the University of Leicester in England, one of the authors of the study said: “What’s most likely to happen is the star’s orbit will gradually decay and it will get closer and closer to the supermassive black hole until it gets close enough to be completely disrupted.”

“That process is likely to take years at least — more likely decades or centuries,” Eyles-Ferris added.

“There are lots of unanswered questions about tidal disruption events and exactly how the orbit of the star affects them,” Eyles-Ferris said. 

“It’s a very fast-moving field at the moment. This one has shown us that new discoveries could come at any time.”

For 18 graduates of the Reko Diq Mining Project, the National University of Technology, Islamabad, has started a training program. These graduates will complete an 18-month on-the-job training program at Barrick’s International Mining Sites after completing a two-month course at NUTECH.

The graduates will acquire proficiency in mining and associated technical domains during the training program. The chosen graduates will also get specific instruction on environmental protection, safety, exploration, and geology.

Along with the development of communication skills, the curriculum will also emphasise the most recent advancements in the mining industry. Barrick’s International Graduate Development Program for 2024 includes the Balochistani graduates.

Additionally, nine Baloch graduates were selected in 2023 and transported to Barrick’s facility in Argentina for on-the-job training.

WhatsApp is implementing a new upgrade to refine the Updates tab interface, hence boosting accessibility for status and channel updates.

WABetaInfo reports that the upgrade introduces expedited shortcuts that streamline the updating of statuses and channels. Users can now select and upload photos and videos directly from the interface, reducing the steps involved in choosing media from the gallery.

The Meta-owned messaging application has also revamped the button for generating text-based status updates and introduced a feature for recording and sharing voice status updates. This offers customers a more expedient method to disseminate text and speech updates without depending on the floating action button.

The revisions correspond with recent modifications to other tabs, ensuring a modernised interface that improves navigation and update creation. WhatsApp is modifying the floating action button to facilitate content sharing within channels.

When selecting the floating action button, users will see several options, including creating status updates, starting new channels, or sharing photos, videos, voice, and text in existing channels. This revamp integrates all content-generating options into a singular section.

The new shortcuts are anticipated to be accessible to a broader user base in the forthcoming weeks. Beta testers can currently access them in the latest WhatsApp beta for Android, version 2.24.26.13, available on the Google Play Store.

Through Chinese expertise, the arrangement, which was made possible by the Special Investment Facilitation Council (SIFC), intends to increase Pakistan’s agricultural output.

The Punjab government and China’s “AI Force Tech” company have inked a memorandum of understanding (MoU) to introduce advanced agricultural machinery during Chief Minister Maryam Nawaz’s visit to China.

Through the use of advanced robotic technology, the MoU seeks to transform Pakistan’s agricultural industry, guarantee economic growth, and boost farmers’ wealth with China’s assistance.

Through the partnership, Pakistan would also have the chance to absorb knowledge about China’s sophisticated farming methods.

In the meantime, plans have been revealed by the Federal Minister of Planning to send 1,000 agricultural experts to China to study contemporary farming methods.

A Chinese business and the Punjab government previously inked an agreement to introduce cutting-edge cancer treatment technologies to Punjab.

Maryam Nawaz signed a Memorandum of Understanding (MoU) with Hygea Medical Technologies while she was in China in order to introduce cutting-edge cancer treatment equipment and techniques to Punjab.

This equipment will make it feasible to treat cancer without the need for chemotherapy or surgery.

Following a meeting with Hygea Medical Technologies President Dr. Luo Fuliang, Maryam Nawaz said the organization has promised expert assistance for the establishment of the Nawaz Sharif Cancer Hospital.

She went on to say that the hospital will work with China to treat cancer patients utilizing the newest equipment and techniques following the agreement.

Maryam Nawaz and a high-level delegation are present. From December 8 to December 15, the chief minister will go to Beijing, Shanghai, Shenzhen, and Guangzhou.

CM Maryam Nawaz is expected to attend a number of conferences, events, and meetings with the goal of enhancing bilateral relations and looking into potential joint ventures in the areas of infrastructure development, technology, agriculture, and governance.
