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.

In the wake of the tragic drowning of three students at a resort near Ullal on the outskirts of Mangaluru city, the tourism department in Dakshina Kannada is set to implement comprehensive safety guidelines for properties with swimming pools or beach access. This initiative aims to ensure guest safety and prevent similar incidents in the future.

New Safety Mandates for Resorts and Homestays

Rashmi S.R., deputy director (in-charge) of the tourism department, announced, “We will instruct all homestays and resorts to enforce precautionary measures, especially those with pools or direct beach access. Properties must ensure 24/7 supervision, particularly during guest hours. This tragedy highlights the importance of having trained personnel on-site.”

Key Safety Guidelines

The district, home to around 150 homestays and 130 resorts, will see the following measures enforced:

  • Clearly displaying pool depths.
  • Installing adequate safety equipment, such as life buoys.
  • Employing trained lifeguards at all times.
  • Establishing clear pool operating hours.
  • Reviewing and implementing standard operating procedures (SOPs) for pool and beach usage.

Booming Beach Tourism Calls for Vigilance

Manohar Shetty, president of the Association for Coastal Tourism (ACT), Udupi, highlighted the growing popularity of beachside resorts, particularly during peak seasons. Properties in Udupi, often fully booked with tourists from Bengaluru, Mysuru, Kodagu, and Shivamogga, face increasing pressure to maintain safety standards.

Udupi district boasts 22 beachside commercial properties catering to this rising demand.

Shetty emphasized, “Authorities must scrutinize safety measures and carefully evaluate guidelines before issuing new resort licenses. Panchayats should rely on the Karnataka Town and Country Planning Act when handling such cases.”

Long-Term Solutions for Water Safety

Recognizing the need for a cultural shift in water safety, Shetty proposed integrating swimming lessons into school curricula. This move would not only equip students with essential skills but also encourage safe participation in water-based activities.

A Safer Tomorrow for Coastal Tourism

As the tourism sector thrives, Mangaluru’s proactive approach underscores its commitment to visitor safety. The tragic incident serves as a wake-up call, propelling the industry towards stricter regulations and better preparedness, ensuring that coastal vacations remain both enjoyable and safe.

Union minister Amit Shah on Friday, November 15, said PM Narendra Modi will amend the Waqf Act despite opposition from leaders like Uddhav Thackeray and Sharad Pawar.

"Modi ji wants to change the Waqf Board law, but Uddhav ji, Sharad Pawar and Supriya Sule are opposing it," Shah said, addressing a rally at Umarkhed in Maharashtra's Yavatmal district.

"Uddhav ji, listen carefully, you all can protest as much as you want, but Modi ji will amend the Waqf Act," he said. Shah said there are two camps in the November 20 Maharashtra assembly polls, one of 'Pandavas' represented by the BJP-led Mahayuti and the other of 'Kauravas' represented by Maha Vikas Aghadi.

"Uddhav Thackeray claims that his Shiv Sena is the real one. Can the real Shiv Sena go against renaming Aurangabad to Sambhajinagar? Can the real Shiv Sena go against renaming Ahmednagar to Ahilyanagar? The real Shiv Sena stands with the BJP," Shah said.

"Rahul Baba used to say that his government would credit money in the accounts of the people instantly. You were unable to fulfil your promises in Himachal, Karnataka, and Telangana," he said.

Shah said the Mahayuti alliance has promised that women will get Rs 2,100 per month under the Ladki Bahin Yojana. "Kashmir is an integral part of India and no power in the world can snatch it away from us," Shah said.

Mangaluru: In a deeply tragic turn of events, a 28-year-old woman named Ranjitha, who had recently given birth but tragically lost her newborn, ended her life by suicide on Monday. She reportedly leapt from the fourth-floor window of Lady Goschen Hospital’s luggage room.

Ranjitha, whose strength and resilience had carried her through a difficult pregnancy, was scheduled for discharge on Monday. Her journey to Lady Goschen Hospital began on October 24, when she was transferred from Karkala. She was a high-risk patient, battling both hypertension and diabetes. At the time of her admission, she was just 27 weeks pregnant.

Due to the complexities of her health, doctors made the difficult decision to perform an emergency C-section on October 30. She delivered a baby girl, premature and weighing only 960 grams. The newborn was immediately moved to the Neonatal Intensive Care Unit, where doctors did all they could. Despite these efforts, the baby passed away on November 3.

Ranjitha’s sorrow was profound. She stayed under hospital care even after her initial recovery and was preparing to go home on November 9. She had even requested a couple more days at the hospital, seeking time perhaps to cope with her unimaginable grief.

On the day of her discharge, a discharge card ready and her family eagerly waiting to take her home, Ranjitha reportedly made her way to the luggage room in the early hours. There, standing on a cot placed for patients' family members, she climbed to a window and fell from the fourth floor. Despite the attempts of another visitor to intervene, tragedy was inevitable. She was rushed to Government Wenlock Hospital, where doctors confirmed the worst—she was no more.

Dr. Durgaparasad M R, the Medical Superintendent at Lady Goschen Hospital, shared his grief and spoke of the ongoing investigation. A post-mortem is to be conducted, and the local Tahsildar will complete the necessary inquest procedures. Ranjitha’s exact reasons for taking this step are yet to be confirmed, though the weight of her recent losses paints a sorrowful picture.
