An exoplanet more than eight times the size of Earth and potentially habitable has been discovered by scientists. Exoplanet K2-18 b was detected by NASA’s James Webb Space Telescope and piqued scientists’ interest after data suggested it may be covered in an ocean and have a hydrogen-rich atmosphere that could support life. Scientists are also encouraged by a hint of the detection of the molecule dimethyl sulphide (DMS). On Earth, DMS is only produced by microbial life, but the team has yet to confirm the detection and search for evidence of biological activity. The groundbreaking discovery of K2-18 b may see the exoplanet come under the unique classification of a “Hycean” planet – ones which are candidates for life thanks to their hydrogen-rich atmospheres and water cover. The amount of methane and carbon dioxide combined with the shortage of ammonia suggests there may be a water ocean underneath a hydrogen-rich atmosphere in K2-18 b. K2-18 b lies within the constellation of Leo and orbits a dwarf star called K2-18. It lies around 120 light years away from Earth and is within the habitable zone. However, scientists added that this does not necessarily mean it can support life. Nikku Madhusudhan, an astronomer at the University of Cambridge and lead author of the paper, explained: “Our findings underscore the importance of considering diverse habitable environments in the search for life elsewhere. “Traditionally, the search for life on exoplanets has focused primarily on smaller rocky planets, but the larger Hycean worlds are significantly more conducive to atmospheric observations.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Georgia prosecutor Fani Willis has requested a 23 October trial for all 19 defendants in the 2020 election subversion case, including former President Donald Trump. Ms Willis was responding to the request for a speedy trial from one of the defendants, lawyer Kenneth Chesebro. His filing didn’t get much attention on Wednesday as former New York Mayor and Trump lawyer Rudy Giuliani stole the spotlight as he surrendered to the authorities in Atlanta and had his mugshot taken. Mr Chesebro made the filing as a legal gamble to throw a wrench into the proceedings in the hopes that Ms Willis wasn’t ready for it, but Ms Willis seemingly called his bluff, according to the Atlanta Journal-Constitution. The issue of the trial date is now up to the Judge in the case. More follows...

Authorities in Greece have issued fresh evacuation orders for parts of Corfu as wildfires erupted on the island. Fires in Rhodes have already forced 19,000 people to leave their homes as holidaymakers said they walked for miles in scorching heat to reach safety. "The smoke was coming. So we all set off on foot. I walked 12 miles (19 km) in this heat yesterday. It took me four hours," British tourist Chris Freestone told the Reuters News Agency. Sea evacuations have now begun from a beach in Corfu to transport individuals fleeing from the fires on the island. Around 59 people were evacuated from Nissaki Beach on the northwest coast, the Greek Coast Guard has said. The evacuation was carried out using six coast guard vessels and nine private vessels. People in Santa, Megoula, Porta, Palia Perithia and Sinies were told to evacuate to Kasiopi due to the raging fires. The Greek government’s Emergency Communication Service has said: “In Rhodes, the Civil Protection forces continue to fight the flames non-stop. Since the first light of day, 10 aircraft, and 8 helicopters, of which 2 are coordinating, have taken off and are operating consecutively. “Regarding the ground forces, there are 266 firefighters, 16 groups of infantry departments, 49 firefighting water vehicles, as well as hundreds of volunteers who support the efforts of the firefighters.” As the wildfires rage on, here is everything you need to know about how a wildfire evacuation protocol works What is a wildfire? The Food and Agriculture Organization of the United Nations (FAO) describe a wildfire as: “Any unplanned and uncontrolled wildland fire that, regardless of ignition source, may require suppression response or other action according to agency policy.” How long does a wildfire last? The National Operational Guidance (NOG) has said a wildfire will burn over a period of time in areas that provide the space over which the fire can move. The NOG said the behaviour of the wildfire is dependent on a number of variables, these include: “its movement across the landscape” which “brings instability within the fire environment caused by changes to the available fuel” as well as “its combustibility and arrangement, the shape of the topography and the effects of weather.” According to the Guinness World Records, the longest wildfire was the Chinchaga Fire in 1950 which grew out of control and ended five months later on 31 October in Alberta - in that time, it burned approximately 1.2 million hectares (3 million acres) of boreal forest. When should you evacuate? According to Readyforwildfire.org, people should leave as soon as an evacuation is recommended by emergency services. Make sure you leave as soon as you receive the news and do not wait for authorities to come to you or to be ordered directly by authorities to leave. “Evacuating the forest fire area early also helps firefighters keep roads clear of congestion, and lets them move more freely to do their job. In an intense wildfire, they will not have time to knock on every door. If you are advised to leave, don’t hesitate,” readyforwildfire.org has said on its website. Here are some steps you can take: Emergency services will know exactly which areas will need to be evacuated and which escape routes you can take, so be on high alert. Be sure to follow the orders authorities give you. Always stay informed, you can do this by checking the latest on your phone, on social media, radio or television. Officials may direct you to a temporary assembly point, where you will be transferred to a safe location. Readyforwildfire.org has said on its website that people should not return to their homes until fire officials determine it is safe. “Notification that it is safe to return home will be given as soon as possible considering safety and accessibility,” it added. Does the UK government help if you’re affected by a crisis abroad? The official government website has said the help the Foreign, Commonwealth & Development Office (FCDO) can give may be limited. It said before you travel you should: Make sure you are covered by travel insurance. Find out if your holiday is financially protected and what your flights are during your holiday. There has been a Crisis Management Unit set up to respond to the situation in Rhodes. They can be contacted at +30 210 368 1730 / +30 210 3681259 / +30 210 3681350. However, people have been advised to contact their airline or travel operator who can assist with a return to the UK. The government website has also said during hot temperatures, people should take extra caution and follow NHS guidelines on how to cope during hot weather. What have airlines said? Jet2 and Tui have cancelled all flights to Rhodes. The Jet2 planes were scheduled to depart full of tourists bound for the Greek island. But the planes were empty and will be used to evacuate holidaymakers fleeing the blaze. On Sunday (23 July), Jet 2 put out a statement on Twitter and said they are “keeping the situation under constant review”. In its full statement, the airline said: “The situation in Rhodes continues to evolve quickly and our absolute priority is the health, safety and well-being of customers and colleagues in the affected areas. We can confirm that: Our in-resort teams are working hard to comply with the guidance of local authorities, and we are continuing to bring more customer helpers and local authorities colleagues to the area.” The airline said it will continue to ask customers in affected areas to follow the advice of the local authorities, as well as “staff in their hotels” It said it was “contacting customers as quickly as possible. The statement continued: “Due to these extraordinary circumstances, we have cancelled all flights and holidays that are due to depart to Rodes up to and including Sunday 30th July. We believe this is the right thing to do for everything, and we will be contacting affected customers with regard to their refund or rebooking options. “We will fly those aircraft to Rhodes with no customers on board so that we can continue to bring customers back to the UK on their scheduled flights.” TUI has also put out a statement and said their teams are “working hard with local authorities in Greece to ensure the safety and wellbeing of all our customers currently on holiday in Rhodes and impacted by the wildfires.” Read More Greece wildfires: Holiday and travel advice as Jet2 and Tui flights cancelled amid extreme weather UK airlines still selling tickets to Rhodes despite wildfire inferno Greece fires – live: Corfu evacuations begin as tourists fleeing Rhodes inferno spend second night in airport ‘Like hell on earth’: Brits evacuated from Rhodes describe Greek wildfires horror Greece wildfires: Rhodes tourists sleep on airport floor awaiting evacuation New evacuations ordered in Greece as high winds and heat fuel wildfires

Ukrainian soldiers successfully repelled attacks along the war frontline at Avdiivka on Tuesday as a new offensive from Russian soldiers erupted near the eastern Ukraine town, officials said. “I can add that our defenders on the Avdiivka front repelled all the attacks of the enemy, no losses of lines and positions were sustained,” colonel Oleksandr Shtupun, the spokesperson of the joint press centre of defence forces, said. He confirmed an escalation of Russian military offensive actions on the same front. He said Ukrainian forces repelled attacks in Keramika, Ocheretyne, Berdychiv, Stepove, Lastochkyne, Tonenke, Avdiivka, and Pervomaiske in Donetsk oblast. Around three Russian battalions launched a ground assault on Monday on the eastern town which remained one of the most heavily fortified areas of Donetsk oblast, officials in Ukraine confirmed. "The invaders also launched air strikes near Berdychiv and Avdiivka. From the morning till now, the civilian infrastructure of Avdiivka and the settlements in the Pokrovske district around it are periodically shelled. Avdiivka was bombarded from tubed artillery and multiple-launch rocket systems,” he said in a national telecast. Ukrainian officials have confirmed that they view Russian attacks along the Andiivka and Donetsk city as active enemy efforts to prevent them from moving forces to Zaporizhzhia. In fresh signs of escalation, Russian tanks and armoured personnel were also seen moving towards Ukrainian lines which were backed by air strikes around 5am on Tuesday morning, reported Kyiv Post citing multiple sources. According to the Ukraine’s general staff of the Armed Forces, Russia targeted more than 130 settlements in Chernihiv, Sumy, Kharkiv, Luhansk, Donetsk, Zaporizhzhia and Kherson oblast with artillery fire. It added that Ukrainian defence forces saw success in the areas east of Klishchiivka and Andriivka. The defence by Kyiv’s troops continued in the south of Bakhmut in Donetsk oblast. In the past 24 hours, Ukrainian Air Force carried out 11 air strikes on Russian positions of concentration of troops, weapons and military equipment and nine air strikes on the anti-aircraft missile system used by Russia. A Russian Su-25 fighter jet and seven drones were also shot down, along with successful attacks on Russian ammunition depot, command post, artillery systems among other critical Russian infrastructure, the general staff said in the latest war update on Wednesday. According to the Russian military bloggers, Moscow’s actions in the Avdiivka area operations were aimed at capturing the city Ukraine took back just last month, the Institute for the Study of War said. They claimed Russian forces wanted to encircle Ukrainian troops. “A successful encirclement of Avdiivka – one of the most heavily fortified areas of the Donetsk Oblast front line – would very likely require more forces than Russia has currently dedicated to the Avdiivka-Donetsk City effort,” it said in its latest assessment.
