Astronomers have discovered a small black hole outside the Milky Way by looking at how it influences the motion of a star in its close vicinity.
The team at Liverpool John Moores University in the UK used the European Southern Observatory's Very Large Telescope (ESO's VLT), situated in the Atacama Desert of northern Chile, to spot the black hole.
The newly found black hole was spotted lurking in NGC 1850, a cluster of thousands of stars roughly 160,000 light years away in the Large Magellanic Cloud -- a neighbour galaxy of the Milky Way. The detection in NGC 1850 marks the first time a black hole has been found in a young cluster of stars (the cluster is only around 100 million years old, a blink of an eye on astronomical scales).
According to Sara Saracino from the Liverpool John Moores University's Astrophysics Research Institute, the black hole is roughly 11 times as massive as our Sun. Astronomers started on the trail of this black hole due to its gravitational influence on the five-solar-mass star orbiting it.
Previously such small, "stellar-mass" black holes have been spotted in other galaxies by picking up the X-ray glow emitted as they swallow matter, or from the gravitational waves generated as black holes collide with one another or with neutron stars.
However, most stellar-mass black holes don't give away their presence through X-rays or gravitational waves.
This is the first time this detection method has been used to reveal the presence of a black hole outside of our galaxy. The method could be key to unveiling hidden black holes in the Milky Way and nearby galaxies, and to help shed light on how these mysterious objects form and evolve, the team said.
"Every single detection we make will be important for our future understanding of stellar clusters and the black holes in them," said co-author Mark Gieles from the University of Barcelona, Spain. (IANS/JB)

Mahanadi Coalfields Limited (MCL), a subsidiary of Coal India will set up a 50 megawatt (MW) solar power plant in Odisha's Sambalpur at a total cost of Rs 301.92 crore, moving steadily towards its goal to achieve carbon neutrality by 2024. MCL has placed a turnkey order to set-up a 50 MW solar power plant with a Chennai-based firm M/s Hild Energy Ltd, which will establish this green energy project within a timeline of 10 months, the MCL said in a statement on Saturday.
This solar plant would cater to the captive power requirement of MCL. The Central PSU had successfully set-up a 2MW solar power plant in Sambalpur in 2014. The company said it has pledged a target of installing 182 MW of solar power by 2024 in order to become a net zero energy company, aligning itself to use cleaner forms of energy for coal production.

This 50 MW solar power project will reduce CO2 emission by 91,020 tonnes per annum and carbon offsets of around 24,824 tonnes per annum, claimed the MCL. MCL is the leading production subsidiary of Coal India, having mining operations in Angul, Jharsuguda and Sundargarh districts of Odisha. Having achieved the highest ever capital expenditure of Rs 2,419 crore in the financial year 2020-21, the company has coal production and dispatch targets of 163 million tonnes and 182 million tonnes, respectively.
MCL was the coal mining company to introduce environment-friendly surface miner technology, which contributes over 95 per cent in coal production. As another environment-friendly initiative, the company has successfully introduced vertical rippers for blast-less over-burden removal in Hingula and Kaniha opencast projects. (IANS/ MBI)

Amitabh Bachchan wrote on his blog,
"My Father , my all .. November 27th his birth in the year 1907 .. Which makes it his 114th Anniversary .. He is in the heavens, with my Mother and they celebrate .. as do we , in thought word and deed .. (sic). But first."
He then posted the picture followed by elaborate paragraphs. The megastar wrote,
"Those rare moments when one would find himself rushing against the winds to prevent the distance between us and to close it down as soon as it can be.

The World Vegan month of November usually brings with itself an increased amount of dialogue and searches about Vegan lifestyle, sustainable living and clean beauty. Before pondering any further, it is important to understand what the Vegan lifestyle is and how it goes beyond the concept of consuming a plant-based diet. Veganism essentially is a lifestyle that is driven by compassionate choices and an increased awareness of one's actions on the world. Thus motivated by the two, a vegan individual usually carefully curates their day-to-day practices in a manner that does little to no- harm to the planet, the people and all of its inhabitants.
Beauty as industry has time and again been scrutinised for its effects on the consumers and the ecosystem - this can be during the manufacturing process or the effect it has on the consumer's thought processes. Now, as the world moves towards adopting Global Sustainability Goals, committing to a world that works with the natural resources instead of against them - it is only fair for each individual to be curious about making the right choices to make their beauty bag as consciously curated as possible. With multiple brands coming up with new standards of vegan and sustainable beauty, many consumers are left confused and doubting the authenticity of these claims. So here is a quick guide that can help you make the right choices:
Vegan and cruelty free labels: Keeping true to the traditional meaning of Vegan - any vegan beauty product means that it is completely plant based and has no animal ingredients or any of their by-products like honey, beeswax, dairy product etc. Similarly, cruelty-free as a label means that the ingredients or the final product did not test on animals or harm any animals during the production process. One way to test the authenticity is to check if these products are legally certified by PETA (People for the Ethical Treatment of Animals), or verified by Vegan organisations as The Vegan Society and others. Cruelty-free and vegan products are also generally categorized by having cleaner and gentler formulas as they are mostly deprived of harsh chemicals and solvents.

Ethical and natural ingredients: It is equally important to invest in products that use ethically sourced and sustainably harvested ingredients. Since most vegan products tend to be plant derived it is of utmost value to ensure that while the source is nature, the impact of manufacturing is also minimal so that there is no harm done to the environment. Often the face scrubs used by us are most damaging not just to the face and to the marine life as well; thus opting for more natural ingredients rather than synthetic ones is quite beneficial. Some natural scrubbing ingredients are sugar, salt, coffee which are safe for the coral reefs and far gentler than synthetic scrubs.

Sustainable and ecofriendly packaging: While the ingredients and formulation can be certified, it is also important to pay attention the quality, material and nature of the packaging in which the product is being stored. With an increase in clean-beauty standards, the consumption of such products has also increased, thus giving brands the opportunity to further develop their packaging in a manner that is sustainable and its increased quantity does not harm the environment. This could translate into using raw materials that are recycled and can be renewed or even introducing the concept of up-cycling the product packaging for decoration or storage purposes. Fore example, The Body Shop has recently launched a new line of vegan hair care and body butters; that are not only made of 95 per cent ingredients of natural origin but the packaging is made of recycled plastic that can further be recycled thus continuing the recycling system. Their makeup brushes also have wooden handles instead of plastic ones this adds to their classy appearance and use of ecofriendly material.

The above is a small snippet in a long list of things that can help contribute to a cleaner and more consciously lifestyle. Where demand increase, supply follows - as people begin to demand ethical, responsible production and products, more and more brands have begun to deliver. Household names such as The Body Shop have pioneered conversations on clean, green and sustainable beauty for decades - thus making them a frontrunner for several old time vegan people.
