Two planets that could support life discovered
Madrid: Two exoplanets that have been discovered, which are warm similar to Earth and may have water, could be good candidates 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 Celcius and 100 degree Celcius, 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.

Speaker rules out discussion on Guv''s conduct amid K''taka Assembly standoff
Bengaluru (PTI): In an effort to end the logjam over the Governor's address that has stalled proceedings for the past week, Karnataka Assembly Speaker U T Khader on Wednesday ruled that legislators should not discuss Thaawarchand Gehlot or his conduct in the house, saying such debates send the wrong message to the public.
The House has witnessed repeated disruptions and adjournments since the session began on January 22 over the issue of the governor's conduct.
During his address to the joint sitting of the Karnataka legislature on January 22, Gehlot read out only three sentences from the 122-paragraph speech prepared by the state government.
The speech included criticism of the Centre for replacing the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) with the Viksit Bharat–Guarantee for Rozgar and Ajivika Mission (Gramin) (VB-G RAM G), portions of which the governor declined to read.
Concluding his address in about two minutes, the governor left the house, triggering a commotion as Congress legislators attempted to gherao him and raised slogans.
While the opposition BJP accused the ruling Congress and its ministers of "insulting" the governor and demanded action, the treasury benches countered by claiming the governor had "insulted the National Anthem by leaving before it was played."
The house again witnessed heated arguments on the issue earlier in the day, leading to adjournment.
During the interruption, Khader held a meeting with ministers and opposition members to resolve the impasse.
When proceedings resumed, the speaker delivered his ruling.
Referring to the events of January 22 and the subsequent debate, Khader said the conduct and discussions had conveyed the wrong message to the public.
"Our conduct as members of this House and the opinions expressed must be in good taste and in accordance with constitutional provisions. They must uphold the dignity of the House and its members. We must introspect in this direction," he said.
He stressed the need for caution to ensure that such incidents are not repeated in the future.
"Let us end this matter here, continue the discussion on the motion of thanks to the governor, and refrain from discussing the governor or his conduct in this house," the speaker said.
Leader of the Opposition R Ashoka said the house should express regret over what he termed an "insult" to the governor.
Responding, Chief Minister Siddaramaiah said the situation would not have arisen had the governor read out the entire address.
"Asking the house to express regret is not appropriate. Why did the governor leave even before the National Anthem was played," Siddaramaiah asked.
BJP MLA S Suresh Kumar reminded Siddaramaiah that as Leader of the Opposition in 2011, he had asked then Governor Hansraj Bhardwaj to curtail his address.
Bhardwaj had subsequently placed the address on the table of the house, requesting members to treat it as read.
Siddaramaiah said the situation in January 2011 was different from the present one.
The debate grew intense, leading to another adjournment of the house.
