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.

Iran’s Islamic Revolution Guards Corps (IRGC) has killed or captured 69 terrorists linked to the Israeli spy agency Mossad during a major counterterrorism drill in the country's southeast, its spokesman says.  

General Ahmad Shafaei, the spokesman for the “Martyrs of Security” drill, said Friday that a total of 23 terrorists have been killed and another 46 arrested in various clean-up operations ever since the IRGC Ground Force launched it in the Sistan and Baluchestan province on November 1.

Seven terrorists have also turned themselves in during the period.

“The undeniable fact about terrorists is that they rely on arrogant powers, particularly the intelligence service of the wicked and vicious Zionist regime," Shafaei said.

“Unfortunately, weapons and munitions at terrorists’ disposal are among the most sophisticated ones in the world. This accounts for their heavy dependence.” 

The official stated that several members of the disbanded terror teams were non-Iranian nationals, who had been hired by foreign intelligence agencies to carry out acts of sabotage and terror inside Iran.

In a most recent operation, six terrorists were arrested and four others were eliminated, three of whom were non-Iranians, he added. 

On October 26, ten members of Iran's law enforcement forces were killed in a terrorist attack in the Gohar Kuh district of Taftan in the Sistan and Baluchestan province.

The so-called Jaish al-Adl terrorist group claimed responsibility for the assault, which was one of the deadliest in the province in recent months.

The group has carried out numerous terrorist attacks in Iran, primarily in Sistan and Baluchestan.

Its tactics include the abduction of border guards as well as targeting civilians and police stations within the province to incite chaos and disorder.

In January, Iran launched a military operation during which the headquarters of the Pakistan-based terrorist group was targeted in missile strikes, destroying its infrastructure.

Udupi, Nov 11: A traveller reportedly lost ₹4.1 lakh after attempting to book a cab online in Udupi. 

At around 1:30 PM on November 7, the man from West Bengal searched for car rentals on Google and selected a website named "Shakti Car Rentals." Shortly after, he was contacted by someone claiming to be "Rohit Sharma," who directed him to pay a registration fee of ₹150 on the site.

After unsuccessful payment attempts via both his Canara Bank debit card and SBI credit card (without receiving an OTP), "Rohit Sharma" instructed him to pay the driver directly. But at 1:47 PM, he received messages showing deductions of ₹3.3 lakh from his SBI credit card and ₹80,056 from his Canara Bank debit card, totaling ₹4.1 lakh.

The complainant alleges fraud through a deceptive link disguised as a booking token fee. A case has been registered at Udupi Town Police Station.

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.
