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.

Bengaluru, Nov 22: For the second day running, the Karnataka BJP on Friday staged a statewide protest condemning the government’s alleged move to notify land of farmers as Waqf property.

The BJP staged a protest before the offices of Deputy Commissioners at district headquarters.

The BJP leaders are vehemently demanding that the state government cancel a 1974 Gazette notification in this regard.

The agitators are also demanding scrapping of the Waqf Board and the resignation of Chief Minister Siddaramaiah and Minister for Waqf and Housing Zameer Ahmad Khan.

The BJP MLAs, MLCs, MPs gathered in the premises of Freedom Park and staged a protest under the leadership of Leader of Opposition R. Ashoka and slammed the state government.

MLA T.S. Srivatsa led the protest in Mysuru and hundreds of party workers and farmers staged the protest under the leadership of former MP Pratap Simha in Kodagu.

Former MP Sumalatha Ambareesh led the agitation in Mandya.

This was the first time that Sumalatha took part in the party’s programme after the Lok Sabha elections.

State President B.Y. Vijayendra claimed, “The Congress government in Karnataka is issuing notices to farmers claiming the ownership of their lands to the Waqf Board and pushing them on the streets overnight.”

In the first week of December, three teams formed by the BJP will travel across the state and record the grievances of farmers.

“The state government is attempting to snatch away the lands belonging to temples as well,” Vijayendra alleged and added that the teams would comprise all senior leaders of the BJP.

Meanwhile, the police have taken Sri Ram Sena chief Pramod Muthalik into custody while staging a protest march to the office of Zameer Ahmad Khan in Bengaluru.

Muthalik along with Hindutva activists was planning to lay siege to Zameer’s office over the Waqf row.

The police stopped Muthalik and requested him to submit the memorandum by reaching the minister’s office in a vehicle. However, Muthalik refused to go with the police and continued his footmarch. The police took him into custody following arguments.

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.
