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, Oct 22: A Mangaluru resident has fallen victim to a ₹20 lakh scam after being lured into a fraudulent investment scheme by individuals posing as representatives of J.P. Morgan India. The case, filed at Kadri police station, highlights the growing threat of investment fraud in the region.

The victim, whose identity has not been disclosed, was contacted on September 24 by a man named Vishwanathan, who falsely introduced himself as the Chief Investment Strategist for J.P. Morgan India. Shortly after, a woman named Neeta Sharma reached out, using multiple phone numbers to convince the victim of her association with the prestigious financial firm. She shared a company link and urged the victim to invest ₹20 lakh, promising high returns.

On October 14, after being convinced by Neeta's claims, the victim transferred ₹20 lakh to the fraudulent account. Following this, Neeta instructed the victim to purchase 1,000 shares at ₹240 per share, which he did. The next day, she advised buying 7,900 more shares at ₹250.95 each, further strengthening her false credibility.

However, trouble arose when Neeta told the victim to withdraw the invested amount. Instead of receiving the full sum, the victim was sent only ₹1,500, transferred from an unknown account. When questioned, Neeta could not provide a clear explanation for the discrepancies.

Sensing the deceit, the victim demanded a full refund of his investment. Neeta, however, brazenly asked for an additional ₹4 lakh, prompting the victim to realize the extent of the fraud. He then filed a formal complaint with the Kadri police.

This incident serves as a critical reminder for the public to remain vigilant against fraudulent schemes, particularly those involving investment promises from unverified sources. Always ensure that you verify the legitimacy of financial institutions and representatives before transferring funds. 

The Kadri police are investigating the case and have urged the public to stay alert and report any suspicious investment schemes.

Tips to Protect Yourself from Investment Scams:

1.    Verify Credentials: Always cross-check the credentials of anyone claiming to represent a reputable financial institution. Use official contact information from the company's website to verify.

2.    Be Skeptical of Unsolicited Offers: Be cautious of unexpected investment offers, especially those that promise unusually high returns.

3.    Conduct Thorough Research: Before investing, investigate the company and the proposed investment thoroughly. Look for reviews, ratings, and any red flags.

4.    Report Suspicious Activity: If you suspect a scam, report it immediately to local authorities or financial regulatory bodies to prevent further fraud.

Bengaluru, Nov 1: Hardline BJP leader and Vijayapura MLA Basanagouda Patil Yatnal wrote a letter to Prime Minister Narendra Modi to "Nationalise Waqf Assets", alleging Waqf board of "blatant violation" in claiming of the lands of Farmers, temples and mutts.

Taking to his social media, Basanagouda Patil Yatnal posted on X, saying "I have written a letter to the hon'ble PM Shri Narendra Modi ji to Nationalize the Waqf Assets in view of the arbitrary, blatant violation in claiming of the lands of Farmers, Landowners, Temples, Trusts and Mutts across the country by the Waqf board. All the citizens of the country have equal rights on the land. If the motive of Waqf is welfare and social service, this has to be done without bias and religious discrimination as India is a secular nation."

Additionally, Vijayapura MLA also attached the letter to Prime Minister Narendra Modi in his post.

Earlier, BJP MP Tejasvi Surya had accused the Waqf Board of encroaching on thousands of acres of farmers' lands with the support of the Karnataka government.

Surya stated, "There have been multiple press conferences and videos in the public domain where the Minister himself has admitted that these Waqf adalats are being conducted under the Chief Minister's instructions. This is a grave matter, where thousands of acres of farmers' lands are being encroached upon by the Waqf Board with the active support and collusion of the State Government."

He mentioned that, in recent days, farmers from various districts across Karnataka have reported that, without prior notice, ownership of their lands has been abruptly transferred to the Waqf Board.

Karnataka Minister Priyank Kharge criticised BJP MP Tejasvi Surya, claiming he has done nothing for Bengaluru. Kharge's remarks came in response to the BJP MP's accusations regarding Waqf Board land encroachment.

The Congress leader assured that the Karnataka government is committed to protecting farmers' properties.

Kharge further questioned the BJP's record on protecting temples during its previous government, stating that the Karnataka government is committed to safeguarding temples and common people's properties.
