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.

The media office in the Gaza Strip, where the Israeli regime has been waging a genocidal war since last October, says as many as 188 Palestinian journalists have been killed since the onset of the brutal military onslaught.

The office provided the figure on Saturday, naming four journalists as the most recent victims of the onslaught.

It identified the foursome as Zahraa Mohammad Abu Sukheil, Ahmad Mohammad Abu Sukheil, Mustafa Khadr Bahar, and Abdel Rahman Khadr Bahar.

The office said it “strongly condemns the targeting, killing, and assassination of Palestinian journalists by the Israeli occupation and holds it fully responsible for committing this heinous crime.”

“We call on the international community, international organizations, and those involved in journalistic work worldwide to take action against the occupation, pursue it in international courts for its ongoing crimes, and pressure it to halt the genocide and the targeted killings of Palestinian journalists,” it said.

Earlier in the day, the office said the Israeli regime had bombed the tents sheltering journalists and displaced persons at the al-Aqsa Martyrs' Hospital in the city of Deir al-Balah in central Gaza for the ninth consecutive time.

The atrocity that claimed the lives of two people and injured 26 others came as part of “the genocidal crimes committed by the Israeli occupation army against hospitals, civilians, and displaced persons,” it said.

The media office held the regime and the United States, its biggest ally, as well as other countries aiding the genocide fully responsible for such systematic crimes.

At least 43,552 Palestinians, mostly women and children, have been killed and 102,765 others wounded since the launch of the war that followed a retaliatory operation by Gaza’s resistance groups.

The fatalities include 44 people, who were killed across the coastal sliver, in the most recent phase of the military onslaught.

As many as 24 of the victims were killed in the northern part of the territory, where the regime has markedly intensified its deadly attacks for weeks.

They included an eight-year-old child and a five-year-old one, who lost their lives after Israeli warplanes targeted a group of minors filling up jerry cans with water alongside their mother at the Jabalia Refugee camp.

Gaza’s heath ministry, meanwhile, said a number of victims remained under the rubble and in the streets following Israeli airstrikes, saying ambulances and civil defense teams could not reach them due to the sheer extent of the destruction caused by the raids and obstruction caused by the regime.

Also on Saturday, the Integrated Food Security Phase Classification (IPC) report, a United Nations-backed assessment, warned that famine was looming in northern Gaza amid escalated Israeli aggression and the regime’s near-total siege of the targeted areas.

The alert from the Famine Review Committee warned of "an imminent and substantial likelihood of famine occurring, due to the rapidly deteriorating situation in the Gaza Strip."

On October 17, the body projected that the number of people in Gaza facing "catastrophic" food insecurity between November and April 2025 would reach 345,000, or 16 percent of the population.

The IPC report classified that figure as Phase 5 -- a situation when "starvation, death, destitution, and extremely critical acute malnutrition levels are evident."

The Israeli military, however, questioned the report's credibility.

"To date, all assessments by the IPC have proven incorrect and inconsistent with the situation on the ground," the army said in a statement, denouncing "partial, biased data and superficial sources with vested interests."

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.

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.
