Two habitable planets that could support life discovered

Two exoplanets that have been discovered, which are warm similar to Earth and may have water, could be alternatives to support life, according to a study on Tuesday.

Scientists have been searching for planets close to nearby stars since 2016 using a 3.5-meter telescope.

Images captured at the Calar Alto Observatory in Almeria, southern Spain, and two other Spanish telescopes allowed researchers to analyse, in great detail, the Teegarden star—a cold red dwarf only around 12.5 light years away from our solar system, Efe news reported.

"Teegarden only has eight per cent of our sun's mass," said Ignasi Ribas, co-author of the study. "It is much smaller and much less brighter than the Sun. In fact, despite being very close to the Earth it was not discovered until 2003," Ribas said.

The temperature of the star is around 2,600C (the Sun's temperature is 5,500C) and because it is 10 times smaller, it's 1,500 times weaker and radiates mostly infrared waves.

Once the star was found, scientists used the Doppler technique, also known as the wobble method, which uses radial-velocity measurements of the parent star to detect planets around it.

The Doppler technique detected at least two signals, which have now been identified as planets Teegarden b and Teegarden c.

Teegarden b has the mass similar to Earth and orbits the star every 4.9 days. The second planet takes 11.4 days to complete the orbit, which is the length of its year.

"In other words, they are much closer to their (parent) star than the Earth is to the Sun," Ribas said.

"Teegarden, the more internal one, receives 10 per cent more light than we do from the Sun, that's why we think it may be too hot and may not have water. But this is just speculation because there are elements of its climate that we don't know and that could mean there could be liquid water," he continued.

Teegarden hovers in the midst of a habitable zone, which means the temperature on its surface is between 0 degree Celsius and 100 degree Celsius, meaning it could very well have water on surface.

What scientists are excited about is that both exoplanets are excellent candidates to support life, alongside Proxima, which to date was the planet that presented the best conditions for habitability.

Experts believe between the closest star to our solar system -- Proxima Centauri that is four light years away, and Teegarden (the 24th furthest away at 12 light years) -- there are dozens of stars, some with planets orbiting them, but "apart from Proxima, none of them present ideal conditions (for life)," Ribas said.

Researchers have not ruled out the possibility of there being more planets orbiting Teegarden, but the system would have to be observed in more detail. "These planets are of great interest in order to search for life in the mid-term," Ribas said.

Without doubt, for the scientist, the forthcoming decade will be thrilling and key in space exploration and the search for suitable terrestrial exoplanets.

Udupi, Nov 11: The Karkala town police in Udupi have arrested Krishna Naik, the sculptor responsible for installing a 33-foot Parashurama statue at Umikkal Hill in Bailur, Karkala taluk. 

Naik, the owner of Krish Art World and a resident of Bengaluru's Visvesvaraya Layout, was apprehended in Mahe, part of the Union Territory of Puducherry, for allegedly substituting a look-alike statue in place of a genuine bronze figure at the Parashurama Theme Park in Karkala.

Udupi Superintendent of Police Dr. Arun K confirmed the arrest, stating that Naik faces charges under Sections 420 (cheating) and 409 (criminal breach of trust) of the Indian Penal Code. 

This legal action followed a complaint lodged in June by Krishna Shetty, a resident of Nallur village, Karkala. Shetty claimed that Naik had received a payment of ₹1,25,50,000 from Udupi Nirmithi Kendra for the installation of a bronze Parashurama statue. However, Naik allegedly deceived the government by installing a replica instead.

The statue was unveiled on January 27, 2023, by then Chief Minister Basavaraj Bommai. Current Chief Minister Siddaramaiah has since ordered a CID investigation to probe deeper into the alleged fraud surrounding the statue's installation at the theme park.

Prominent NRI community leader SM Syed Khalilur Rehman, fondly known as CA Khalil, passed away in Dubai on Thursday at the age of 86 after a brief illness.

Khalil had been admitted to Aster Hospital in Mankhool on Tuesday after experiencing severe leg weakness. Despite the best efforts of the medical team, he succumbed to a double heart attack that worsened his condition, his son Rais Ahmed confirmed.

The news of his passing has sent waves of grief across communities, particularly in his hometown of Bhatkal, Karnataka, where he was a celebrated figure. Tributes have been pouring in on social media, highlighting his significant contributions to international trade, social service, and education.

A Legacy of Leadership and Service

A chartered accountant by profession, Khalil was a founding member of the Dubai chapter of the Institute of Chartered Accountants of India (ICAI), where he served as chairman from 1987 to 1994. His illustrious career included key leadership roles, such as general manager of Khaleej Times, group executive director of the Ilyas and Mustafa Galadari Group, and vice-chairman of the Jashanmal Group of Companies.

He also chaired Maadhyama Communications and Sahil Online, a web-based news platform, and was a director and trustee of several media companies and charitable organisations in Dubai and India.

A Champion for Education and Philanthropy

Khalil’s impact extended far beyond his professional achievements. As president and general secretary of Anjuman Hami-e-Muslimeen, he played a pivotal role in the development of educational institutions, including schools and colleges in Bhatkal and surrounding areas. His dedication to social upliftment earned him recognition from the Government of Karnataka, which honoured him with a prestigious award for his philanthropic contributions.

A Life Celebrated

The Bhatkal Muslim Khaleej Council (BMKC) recently released a documentary celebrating Khalil’s remarkable life and service to the community—a testament to his enduring legacy.

CA Khalil is survived by his family and countless admirers across the globe. His passing marks the end of an era for Indian expatriates in the UAE and beyond, leaving behind a legacy of leadership, generosity, and commitment to community service.
