Glass-based paint keeps things cool by reflecting sunlight

By - August 17, 2015 1 Picture

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.

Astronomers discover Jupiter's twin orbiting a distant Sun-like star

By - July 20, 2015 1 Picture

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.

UK consortium proposes mission to provide five-day warning of solar storms

By - July 8, 2015 3 Pictures
Solar storms – or Coronal mass ejections (CMEs) – are caused by the sudden release of built-up magnetic stress in the Sun's atmosphere. On Earth, we see the results of small versions of these when plasma streaming from the sun strikes our upper atmosphere and creates the Northern and Southern Lights (the Aurora Borealis and the Aurora Australis). Sometimes, however, these ruptures can be inordinately large and have the potential to wreak havoc on orbiting satellites, radio networks, and national power grids. In an effort to be prepared well in advance of such events, a UK consortium has proposed a satellite system that can provide as much as five days warning of potentially damaging CMEs. Read More

Shadow Wi-Fi fights skin cancer by keeping sun worshippers in the dark

By - May 4, 2015 1 Picture

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.

Stellar viewing: The solar eclipse in pictures

By - March 23, 2015 13 Pictures
Friday morning bore witness to a stunning solar eclipse, as our Moon traversed the face of our parent star, blocking its light in a beautiful example of the intricate orbits negotiated by the planets and moons that make up our solar system. For those able to secure a pair of protective glasses and be charmed enough to gaze through cloud-free skies, the sight was a spectacular one – a rare meeting of two celestial bodies that have accompanied each of us through every day and night of our lives.

ESA satellites set to view Friday's solar eclipse

By - March 19, 2015 2 Pictures
The ESA is preparing a number of its orbital assets to observe Friday morning's solar eclipse, when the Moon will pass in front of the Sun's disk, blocking the light from our parent star in spectacular fashion. The event will be viewable to most of Europe, however the degree to which the Moon will obscure the Sun will vary depending on location. Viewers in parts of Norway will experience a total eclipse, while those watching from Rome will only see 56 percent of our star's surface covered. Read More

World's biggest solar telescope set for 2019 completion in Hawaii

By - February 14, 2015 3 Pictures
The US$344 million Daniel K Inouye Solar Telescope (DKIST) is designed to image the surface of the Sun in unprecedented detail and help scientists address fundamental questions about solar physics when it opens sometime in 2019. The DKIST has just entered the next phase in its construction, with a consortium of eight UK universities and businesses tasked with producing the telescope's all-important cameras. Once complete, it will be the biggest solar telescope in the world – dwarfing current titleholder Big Bear Solar Observatory in California and edging out the 4.07 m (13.12 ft) European Solar Telescope that's also currently under construction.

Rosetta prepares for a close encounter with Comet 67P/Churyumov–Gerasimenko

By - February 7, 2015 1 Picture
ESA's Rosetta orbiter is preparing to make a daring 6 km (3.7 miles) pass of one of Comet 67P/Churyumov–Gerasimenko's most active regions – an area on the comet's larger lobe designated as Imhotep. As the comet moves closer to the Sun, mission controllers are expecting to see an exponential increase in volatile activity, and ESA hopes that the new orbits planned for the little probe will allow scientists to gain a better understanding of these effects.
