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.

Mangaluru: The MLC by-election for the Dakshina Kannada and Udupi Local Authorities Constituency commenced at 8 AM on Monday, with voting set to continue until 4 PM. A total of 392 polling booths have been established across the two districts, which form the constituency.

The constituency has 6,032 eligible voters, including 3,127 women. Early reports indicated brisk voting at the Mangaluru City Corporation polling booth, where corporators were seen patiently standing in line in the morning.

In a unique moment, Sharath, a gram panchayat member from Kokkada, cast his vote at Kokkada Gram Panchayat before heading to his wedding ceremony.

The constituency features 53 sensitive polling booths. Eligible voters include members of gram panchayats, corporators from Mangaluru City Corporation, city and town municipal councils, town panchayats, MLAs, MLCs, and Lok Sabha members representing the Dakshina Kannada and Udupi districts.

Notably, Byndoor MLA Gururaj Gantihole and MLC Prathap Simha Nayak, who do not represent local bodies, were left out of the voters' list. According to electoral rules, only those MLAs, MLCs, and MPs who represent city corporations, municipalities, town panchayats, taluk panchayats, or zilla panchayats are granted voting rights in the MLC elections for the Local Authorities’ Constituency.

Udupi: Falling prey to a sophisticated a “digital arrest” scam, Prameela (39) found herself defrauded of a staggering ₹11,87,463. The plot, orchestrated through deceptive tactics, left her financially devastated.

On October 25, Prameela received a call from an unknown number claiming a parcel, allegedly sent by one Wang Ming Zi, was flagged due to containing suspicious items: 5 kg of clothes, 8 ICICI credit cards, and 700 grams of MDMA. Adding to the urgency, the caller asserted that an FIR had already been filed against her.

The caller then transferred Prameela to a supposed representative of the 'Bombay Cyber Crime Branch,' who introduced himself as Manish Kumar, claiming to be a senior executive at DTDC Mumbai. Manish directed her to connect via Skype video call, asking her to download the app and search for the ID [email protected].

Once on the call, Prameela was requested to provide her Aadhaar card details, which she complied with. She soon received what appeared to be a formal arrest order listing her name, address, and Aadhaar information. Under pressure, Prameela disclosed her bank account details and balance to the caller. Exploiting this trust, the scammer then transferred ₹11,87,463 from her account.

Following the incident, Prameela lodged a complaint with the Shirva police, who have since registered a case under sections 316(2), 318(4), 351(2) of the BNS, and 66(C), 66(D) of the IT Act. The authorities are now investigating this alarming case of digital fraud.

The accused wife and the victim husband

 

Udupi, Oct 25: A seemingly natural death has unraveled into a heart-wrenching case of betrayal and murder in Udupi’s Marne village. 

Balakrishna (44), who had been battling fever and severe illness for nearly a month, succumbed to his condition on October 20, despite extensive treatment at multiple hospitals. 

Diagnosed with jaundice, he was under care at KMC Hospital in Manipal, Wenlock Hospital in Mangaluru, NIMHANS Hospital in Bengaluru, and Victoria Hospital. But his symptoms persisted, and he was brought home on October 19, only to pass away at 3:30 am the next morning.

A complaint filed by his grieving brother, Ramakrishna (42), has now transformed Balakrishna's case into an alleged murder investigation. According to Ramakrishna, his brother’s wife, Pratima, had been in a relationship with Dileep from Hirgan. Allegedly, frustrated by Balakrishna's interference in her relationship, Pratima conspired with Dileep to eliminate him.

The complaint suggests that Pratima and Dileep plotted to gradually poison Balakrishna, lacing his meals with a toxic substance that steadily worsened his health. 

In the early hours of October 20, Dileep allegedly visited the home, where he and Pratima are accused of suffocating Balakrishna with a bedsheet, ending his life in a final act of betrayal. 

The Ajekar police have now registered a murder case, transforming Balakrishna's tragic death into a haunting investigation. They also have managed to arrest the victim’s wife and her boyfriend.
