"Finding a 'sister Earth' is a challenge for the next 20 years", Nobel Prize in Physics assures

CNN Portugal30 August 2026 at 08:33

The Nobel Prize in Physics stated that finding a "sister Earth", meaning a planet with conditions similar to Earth's, represents a challenge that should take at least 20 years to overcome. The declaration reinforces the complexity involved in the search for habitable worlds outside the solar system.

Science has already confirmed that Venus, the neighboring planet to Earth, has extreme conditions that make it uninhabitable. The European Space Agency (ESA) described Venus's environment as "hellish", characterized by temperatures that exceed those of a conventional oven.

These extreme temperatures on Venus exemplify the difficulties that scientists face in identifying planets with characteristics conducive to life. The neighboring planet serves as a warning about the technical and scientific challenges necessary to achieve the goal of finding an Earth twin.

Pots in the sun: why the roots cook before the plant dries out

This article explains why plants in pots wilt even when the soil is moist, debunking the mistaken idea that lack of water is always the cause. The real issue is the overheating of roots inside pots, which on balconies can reach extreme temperatures due to sun exposure on multiple sides and the lack of soil mass to regulate temperature, unlike in garden beds where soil acts as a thermal buffer. The article warns that watering an overheated plant does not solve the problem and can even make it worse, leading to the plant's death within a week, when the usual conclusion is that it needed more water.

What you need to know before thawing food

This article warns about the risks of thawing perishable foods, especially raw meat, at room temperature on the kitchen counter. According to the publication, this method is unsafe because it allows bacteria present in foods to multiply, and some can produce heat-resistant toxins that are not eliminated even during cooking. The article aims to raise awareness about safe thawing practices to prevent foodborne illnesses.
