NASA has released a half hour video of our Sun in breathtaking 4K detail. The video was created from images and data captured by the agency's Solar Dynamics Observatory (SDO) as it continues its mission to observe solar activity and unlock the mysteries surrounding the interior mechanics of our parent star.
One of the challenges facing designers of traditional flat solar panels
is the fact that the sun doesn't conveniently stay in one place. This
means that in order for a panel to receive as much sunlight as possible,
it has to pan with the sun as it moves across the sky. While
there are motorized assemblies designed to do just that, they add
complexity, weight and expense to photovoltaic systems. Now, however,
University of Michigan scientists have developed a simpler alternative –
and it's based on the ancient Japanese cut-paper art of kirigami.
Whether it’s slides at playgrounds or roofs of houses, there are some things that you just don’t want to heat up in the sun. Not only does it make them uncomfortable to touch, but it also causes them to age prematurely. While painting such surfaces white is one approach, a scientist at Johns Hopkins University has developed another – reflective paint made from glass.
In the gloomiest corners of a home, an artificial light will often not provide adequate brightness. A new device, however, is aimed at brightening up a room with the brightest light of them all: the sun. Lucy is a solar-powered robotic mirror that reflects natural light into your home.
A team of international astronomers has discovered a gas giant orbiting a distant star with characteristics remarkably similar to those of our own Jovian planet, Jupiter. The significance of the discovery is that the gas giant was found to orbit roughly the same distance from its host star HIP 11915, as Jupiter does from the Sun. This positioning may have profound implications for creating conditions favorable to the development of a habitable Earth-like planet in HIP 11915's inner solar system.
Reaching 67P/Churyumov–Gerasimenko with Rosetta was an incredible feat of science and engineering that has revolutionized how we understand comets, but the fact is that the orbiter and its Philae partner are just entering the interesting part of their mission. Join us as we take a look at what can be expected as Rosetta travels ever closer to the Sun.
Awareness campaigns, sunscreen and mending the hole in the ozone layer have all played a part in the battle against skin cancer. But the beachgoers of Peru now have another form of relief from the sun's harmful UV rays. Aimed at drawing in roasting folk who could do with some respite, ad agency Happiness Anywhere has installed towering sun shades and a free Wi-Fi network that only functions when the users are in the shadows.
