Scientists discover 24 suitable life conditions planets and one in particular would be better than Earth: Planet Earth is the most fit for life. Or at least that was believed until now, as humanity had not found a different planet that harbored life.
However, a new study published in the journal Astrobiology has just refuted that belief.
Thus, scientists have found up to 24 planets outside the Solar system that may have more suitable conditions for life than Earth.
In addition, they could have stars with a longer lifespan than the sun, according to Sky News.
Dirk Schulze-Makuch, a geobiologist at Washington State University with experience in planetary habitability, led the research and detailed the characteristics of possible "superhabitable" planets: they are older, slightly larger, somewhat warmer and possibly more humid than the Earth.
Also, the first 24 candidates discovered are more than 100 light years away, which means it is difficult to see them up close.
However, Schulze-Makuch has stated that the study could help focus future world observation efforts, using, for example, NASA's James Web Space Telescope, the LUVIOR space observatory or the European Space Agency'S PLATO Space Telescope.

"We need to focus on certain planets with the most promising conditions for complex life. But we have to be careful not to get stuck looking for a second Earth, because there could be planets that could be more suitable for life than ours, " said Schulze-Makuch.
"But you have to know that habitability does not mean that these planets necessarily have life, just the conditions that would be conducive," he clarified.
In this sense, astronomers created a "criterion of superhabitability", which they used against 4,500 known exoplanets. Habitability was not defined as definitive signs of life, but meant that the conditions necessary for life to prosper were present.
The team examined systems with G stars that have a short life of less than 10 billion years, similar to The Sun, as well as systems with dwarf stars K.
Since about 4 billion years passed before any complex life forms appeared on Earth, many Sun-like stars, which are the G-stars, could run out of fuel before complex life developed.
Dwarf K stars are much smaller and colder, and have long life periods ranging from 20,000 to 70,000 million years, which would allow planets in orbit to be older and give more time to the evolution of complex life.
However, to be habitable, planets would not have to be so old because they could have exhausted their geothermal heat and lacked protective geomagnetic fields.
The Earth is about 4.5 billion years old, but researchers argue that the optimal point for life is a planet that is between 5.000 and 8.000 billion years old.
But size and mass also matter.
The team searched for planets about 10% larger than Earth, which would mean that there would most likely be more habitable land.
Also, a planet that is approximately 1.5 times the mass of the Earth is expected to retain its inner warming through radioactive decay for longer and to possess a stronger gravity to retain an atmosphere for a longer period of time.
On the other hand, water is key to life and the authors have assured that a little more would help, especially in the form of humidity and clouds.
Similarly, an average surface temperature of about 5 degrees Celsius higher than that of the Earth would also be better for life. This preference for heat and humidity is observed on land with greater biodiversity in tropical rainforests than in colder and drier areas.
None of the 24 planets identified met all criteria for super-habitable planets. However, there is one that meets 4 of the critical characteristics, which means that it may be more comfortable for life than Earth.
"Sometimes it is difficult to convey this principle of super-habitable planets because we believe we have the best planet," Schulze-Makuch revealed.
"We have a lot of complex and diverse life forms, and many that can survive in extreme environments. It's good to have an adaptable life, but that doesn't mean we have the best of everything," he concluded.

Video game giant Razer will launch a prepaid credit card that turns on when you use it
First, Apple released Apple Card, and now Razer releases his own card.
The video game company has revealed that it has partnered with Visa to create Razer Card, a prepaid credit card that will be available in Singapore. The multinational had previously announced its intentions to partner with the payments giant, but did not confirm until Monday the launch of the beta program.
Like Apple Card, It is a virtual card that is accessed through Razer's payment service. The user has the option of obtaining a premium physical card, which is illuminated when making a payment. These are not numbered, according to the company, another feature it has in common with Apple Card.
Razer has not explicitly said whether it will charge users who want the physical card, but it does refer to virtual ones as complementary and explains that an improvement can be made to enjoy the premium service, which implies that there is probably a fee.
It's no surprise that, being a video game company, you try to drag your card into that world. The multinational argues that its reward system will differ from that of other cards by allowing people who use it to have a record and score based on day-to-day tasks and transactions.
The card offers a 1% refund on all purchases and 5% on purchases made through your store and Razer Gold, the company's virtual credit system for purchasing games and content. During the beta program, users will enjoy a 10% refund on purchases made on these last channels.
Razer Fintech, the company's digital payment network in Southeast Asia, is in charge of launching this prepaid card. It may seem like an unexpected move on the part of this company, known for its gaming accessories and laptops, but the multinational believes that its fintech branch plays an important role in its growth strategy, as well as mobile and Cloud video games.
Razer is just one of the tech companies that has made the leap into the world of personal finance. Venmo launched its credit card on the same day and Apple released yours last year. Google has also said it is working on a debit and smart, according to TechCrunch, and Samsung announced this year that it will create a money management system that includes a Mastercard debit card.
