Rain

Astronomers may have found a world where it rains iron. The exoplanet is exposed to thousands of times the radiation that the Earth receives from the Sun, rendering the surface hot enough to vaporize metals that later fall as rain.

Ordinarily, self-driving cars use cameras and other sensors to "see" where they are on the road. However, what happens if the road markings are covered in snow? Well, MIT has developed a system that lets vehicles look beneath the asphalt instead.

The summer of 2018 was marked by extreme weather events like droughts and floods. A new study has pinned the blame on stalled giant waves in the jet stream, and unfortunately they’re expected to only get worse with the changing climate.

Aircraft have been known to mess with the clouds as they pass through or over them. A new study has found that planes could be boosting rainfall and snowfall by up to 10 times, and examined the microphysics behind it.

Titan, the largest moon of Saturn, is a surprisingly dynamic world. Summer was due to hit its northern hemisphere in 2016, but strangely it didn’t seem to arrive as expected. Now, astronomers have analyzed Cassini images and found evidence of rainfall, indicating that finally, summer is coming.

Studying the effects of once-in-a-century rainfall in the hyperarid core of the Atacama Desert in Chile, a team of astrobiologists found that instead of causing a bloom of growth, the unexpected abundance of water killed off three quarters to seven/eighths of the microbe species present.

As useful as solar energy is, it still has one major Kryptonite: gloomy weather. Now, a team of Chinese engineers has developed a hybrid solar cell that can produce electricity come rain or shine, using the triboelectric effect to harvest energy from the movement of raindrops on its surface.

Fresh air might not be quite as fresh as we think. Viruses and bacteria get swept up into the atmosphere in enormous amounts, and now a new study has quantified that amount, finding that untold billions of microorganisms are raining down across the Earth every day.

Using a poncho is one alternative to a full-body cycling rain suit, but German inventor Thomas Schmidt has come up with another … it's a bicycle-mounted umbrella that you stick your head through.​

No prizes for guessing why this Springfield, Missouri-based project is named Cloud House. Designed by artist Matthew Mazzotta, it's aimed at relaxing visitors and highlighting the importance of natural processes like rainfall in allowing us to grow the food we eat.

​When you're driving on a rainy highway, the windshield-covering splashes created by passing transport trucks can be pretty unnerving. You can of course quickly flip your wipers up to High, but Sweden's Semcon has developed a system that is claimed to react even faster.

​If a device has a companion app that gives weather forecasts, then that means the device itself doesn't predict the weather. Nonetheless, we have seen a few app-accompanied products that make such claims. The TARAbrella, however, is different. It's an umbrella that tells you if it's going to rain.​
