New planet found in habitable zone
New planet found in habitable zone
The team actually found three new planets orbiting the star 44 light years away, but only one of them is in the so-called Goldilocks Zone, the band around a sun where temperatures are neither too hot nor too cold for liquid water to exist.
“The star HD 40307 is a perfectly quiet old dwarf star, so there is no reason why such a planet could not sustain an Earth-like climate,” said Guillem Angla-Escude from Germany’s University of Goettingen, who led the research with Mikko Tuomi at the University of Hertfordshire in Britain.
The planet has a mass at least seven times that of Earth but it orbits at about the same distance from its sun, meaning it receives a similar amount of solar energy as Earth gets.
More than 800 planets have been discovered outside our solar system since the first was detected in the early 1990s, but only a handful of those have been in the habitable zone.
Even more rare are planets in the zone that rotate, as this one does, to create a daytime and night-time, which increases the chance of an Earth-like environment. Those that don’t spin are said to be tidally locked, with one half in constant darkness.
“This is the closest one to Earth in a habitable zone that is not tidally locked,” University of Hertfordshire astronomer Hugh Jones told Reuters.
“Just as Goldilocks liked her porridge to be neither too hot nor too cold but just right, this planet, or indeed any moons that it has, lie in an orbit comparable to Earth, increasing the probability of it being habitable.”
WWE stars soften up to children
JEDDAH: The children of Al-Oula — a non-profit organization targeted to break the cycle of poverty — had the most thrilling school trip as they came to see World Wrestling Entertainment (WWE) superstars Mojo Rawley and Mark Henry in King Abdullah Stadium on Tuesday.
The stars sat down in front of 30 students from the institution and softened up as they shared stories from their childhood and introduced their anti-bullying campaign “Be a Star.”
The stars shared personal stories and the difficulties they have faced.
Dean Muhtadi, 31, better known by his ring name Mojo Rawley, told the children: “We are different in many ways but sometimes you have to focus on the similarities and positive aspects of others.”
Mark Henry, 46, opened up about his past: “When I was young, people would call me names and were mean to me, so I decided to become the strongest person in the world.
“I won three world championships in three different world countries that had nothing to do with each other and I am very proud of myself for not letting the mean comments get to my head.”
Henry was world heavyweight champion, and is also a two-time Olympian and a gold medalist at the Pan American Games.
Later, the children had the chance to talk directly with the stars. Rawley is originally Palestinian, so he spoke in Arabic with some of the children.
Henry told one of the students: “If someone is troubling you, don’t give them the satisfaction of letting the comments or actions affect you, and immediately tell your teacher or your parents or any adult, and they will help you through your problems.”
The children then took pictures and were given tickets to the WWE Royal Rumble show on Friday.
“Jeddah is a very family-friendly and a culture-loving city, so I love being here,” Henry told Arab News. “The only difference is the language. Apart from that everyone is very nice and warm.”
On the Royal Rumble, he said: “Get ready for the best entertainment you have ever seen with your own eyes.”
“For someone who comes from an Arab background, this is a historic achievement and it will be remembered for ever,” Rawley said in an interview with Arab News.
“When I first found out that we agreed to a ten-year partnership, it was the coolest thing to find out.
“I am very fortunate to be a part of this long-term partnership which will give the citizens a long time to understand and give us enough time to develop our brand here in Saudi Arabia.
“Last year, the show in Riyadh was a small, non-televised show, but it was one of the coolest experiences of my life, so I am very excited to perform in this grand-scale show. It’s going to be an amazing show. It will rival Wrestle Mania, which is the biggest event of the year.”
Jana Marwan, a nine-year-old student, said: “Everyone told us that the wrestlers were scary but they weren’t. In fact, they were very friendly. They taught us how to look out for ourselves and I had so much fun. I am thankful to them.”
