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 UN special rapporteur for Palestine has slammed Israel’s parliament for passing a law authorizing the detention of Palestinian children, who are “tormented often beyond the breaking point” in Israeli custody.

Francesca Albanese, the UN special rapporteur on the rights situation in the Occupied Palestinian Territory, in a Thursday post on X, characterized the experiences of Palestinian minors in Israeli detention as extreme and often inhumane.

The UN expert highlighted the grave impact of this policy, noting that up to 700 Palestinian minors are taken into custody each year, a practice she described as part of an unlawful occupation that views these children as potential threats.

Albanese said Palestinian minors in Israeli custody are “tormented often beyond the breaking point” and that “generations of Palestinians will carry the scars and trauma from the Israeli mass incarceration system.”

She further criticized the international community for its inaction, suggesting that ongoing diplomatic efforts, which often rely on the idea of resuming negotiations for peace, have contributed to normalizing such human rights violations against Palestinian children and the broader population.

The comments by Albanese came in response to Israel’s parliament (Knesset) passing a law on November 7 that authorizes the detention of Palestinian children under the age of 14 for “terrorism or terrorist activities.”

Under the legislation, a temporary five-year measure, once the individuals turn 14, they will be transferred to adult prison to continue serving their sentences.

Additionally, the law allows for a three-year clause that enables courts to incarcerate minors in adult prisons for up to 10 days if they are considered dangerous. Courts have the authority to extend this duration if necessary, according to the Knesset.

The legislation underscores a shift in the treatment of minors and raises alarms among human rights advocates regarding the legal and ethical ramifications of detaining children and the conditions under which they may be held.

Thousands of Palestinians, including hundreds of children and women, are currently in Israeli jails—around one-third without charge or trial. Also, an unknown number are arbitrarily held following a wave of arrests in the wake of the regime's genocidal war on Gaza.

Since the onset of the Gaza war, the Israeli regime, under the supervision of extremist minister Itamar Ben-Gvir, has turned prisons and detention centers into “death chambers,” the ministry of detainees and ex-detainees’ affairs in Gaza says.

Violence, extreme hunger, humiliation, and other forms of abuse of Palestinian prisoners have been normalized across Israel’s jail system, reports indicate.

Over 270 Palestinian minors are being detained by Israeli authorities, in violation of UN resolutions and international treaties that forbid the incarceration of children, as reported by Palestinian rights organizations.

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.

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.
