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 International Criminal Court (ICC) has issued arrest warrants for Israeli prime minister Benjamin Netanyahu and his former minister of military affairs Yoav Gallant over war crimes against Palestinians in the Gaza Strip.

The court’s Pre-Trial Chamber I issued warrants of arrest for Netanyahu and Gallant "for crimes against humanity and war crimes committed from at least 8 October 2023 until at least 20 May 2024, the day the Prosecution filed the applications for warrants of arrest”, it confirmed in a statement Thursday.

It is the first instance in the court's 22-year history it has issued arrest warrants for Western-allied senior officials.

In its statement, the ICC's Pre-Trial Chamber I, a panel of three judges, said it has rejected appeals by Israel challenging its jurisdiction. 

The chamber said it has decided to release the arrest warrants because "conduct similar to that addressed in the warrant of arrest appears to be ongoing", referring to Israel's ongoing onslaught on Gaza.

Netanyahu and Gallant, it said, “each bear criminal responsibility” for “the war crime of starvation as a method of warfare; and the crimes against humanity of murder, persecution, and other inhumane acts,” as well as “intentionally directing an attack against the civilian population.”

All 124 states that signed the Rome Statute, the treaty that established the court, are now under an obligation to arrest the wanted individuals and hand them over to the ICC in the Hague. 

The court relies on the cooperation of member states to arrest and surrender suspects. The Netherlands' foreign minister quickly said his country was prepared to enforce the warrants while 93 nations earlier reiterated their support for the ICC.

Triestino Mariniello, a lawyer representing Palestinian victims at the ICC, called the warrants "a historic decision".

He noted that the court had endured "pressure and threats of sanctions" from the US government, but acted nonetheless.

As expected, the Tel Aviv regime rejected the rulings, with its security minister Itamar Ben Gvir calling the warrants “anti-Semitic through and through.”

The ICC said Israel’s acceptance of the court’s jurisdiction was not required.

Israel and its major ally, the United States, are not members of the court. 

Israel unleashed its bloody Gaza onslaught on October 7, 2023. So far, it has killed at least 43,985 Palestinians, mostly women and children, and injured 104,092 others, according to the Gaza Health Ministry.

Israel faces an ongoing South Africa-led genocide case at the International Court of Justice (ICJ).
