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: Following allegations by a section of farmers from Vijayapura district that their lands were marked as Waqf properties, Karnataka Chief Minister Sidddaramaiah on Tuesday said none of them will be evicted, and notices issued to them will be withdrawn.

"No farmer will be evicted from their land. Yesterday Revenue Minister (Krishna Byre Gowda), M B Patil (Industries and Vijayapura district in-charge Minister) and Waqf Minister Zameer Ahmed Khan have jointly said that no farmer from Vijayapura will be evicted from their land," Siddaramaiah said.

Speaking to reporters here, he said in case notices have been issued to farmers, they will be withdrawn.

Responding to a question that similar notices have been issued to farmers in Yadgir and Dharwad districts too, the CM said: "I will ask the Revenue Minister to look into it, nowhere farmers will be evicted."

Seeking to clarify "confusion" over 1,200 acres in Honavada of Tikota taluk being marked as Waqf property, M B Patil had recently said it was due to an “error” in the gazette notification.

He also had said only 11 acres out of the 1,200 acres are Waqf properties, and a task force headed by the Deputy Commissioner will be formed to resolve the issues.

Mangaluru: Forest officials successfully captured a leopard that strayed into the kitchen of a house in Akkasaligara Keri, Mulki, on the outskirts of Mangaluru, during the early hours of Sunday, October 20.

Following multiple complaints from residents about leopard sightings, forest department officials had placed cages at various locations in Mulki. According to Deputy RFO Manjunath Ganiga, locals had reported spotting a leopard in the area, prompting the department to set up a cage about a kilometer from the affected house.

At approximately 10 p.m., the leopard entered the house and made its way into the kitchen. The family quickly locked the kitchen door and contacted the forest department for assistance. The forest officials, using a cage and a net, managed to trap the leopard around 2:45 a.m. The animal was later examined by veterinarians and released back into the wild.

Locals suspect that up to three leopards may be roaming the area.

The operation to capture the leopard was led by RFO Kiran Kumar, with assistance from Deputy RFOs Nagesh Billava and Manjunath Ganiga, along with forest department staff members Chandrashekar and Shankar.

A substantial wave of Israeli settlers is migrating to Cyprus, fueling concern over what analysts are calling a “silent occupation” as Israeli buyers snap up properties across the island. Following Israel’s recent military offensives in Gaza and Lebanon, thousands of Israelis have reportedly relocated, seeking real estate and creating enclaves of secretive luxury resorts that cater exclusively to affluent settlers. This shift represents the third major wave of Israeli migration to Cyprus, driven by a mix of war fallout, economic pressures, and Israel's internal political unrest.

Dimitri Lascaris, an investigative journalist and activist, reports on the rapid real estate acquisition in Cyprus, revealing that Israelis have been “buying anything in sight” amid the recent regional crises. He warns of an underlying agenda, stating that Cyprus has historically been viewed by Zionist ideologues as a potential site for a Jewish settlement due to its proximity to Israel and suitability for European-style development. Lascaris draws a link to early Zionist ambitions for Cyprus, recalling the Third Zionist Congress of 1899 when David Trietsch and Theodor Herzl both championed Cyprus as a base for Jewish settlement—a precursor to claiming Israel itself by force.

This migration, which has swelled Cyprus’s Israeli community from 6,500 in 2018 to over 12,000 by April 2024, has sparked an influx of 250-300 Israelis monthly. This quiet but steady stream has led to a larger presence of Israelis in Cyprus, with many pursuing strategic real estate purchases despite legal restrictions. Under Cypriot law, foreign entities can only acquire 500 square meters of land. However, by registering as Northern Cyprus firms and securing at least 51% Turkish Cypriot ownership, Israeli companies can circumvent this rule, enabling them to buy extensive tracts of land.

Cyprus’s geopolitical position—close to Israel, with NATO membership and new gas reserves—amplifies the strategic importance of this quiet expansion. Additionally, the island hosts a significant UK military base at Akrotiri, which has served as a launch point for aircraft bound for Palestinian territories, further heightening the controversy around Israeli-Cypriot connections.

Economically, the high cost of living in Israel and divisive internal issues, such as Prime Minister Benjamin Netanyahu’s contentious judicial reforms, have also driven migration from the occupied lands. According to a Hebrew-language report by Maariv, the first seven months of 2024 saw an exodus of 40,000 Israeli settlers—nearly triple previous years’ numbers—primarily to Cyprus and other nearby regions.
