An extrasolar planet has been caught dragging the outer layers of its host star around with it as it orbits. The newly discovered “tail wagging the dog” phenomenon may be common among massive planets in close orbit around their stars.
Many celestial bodies begin their lives spinning quic...
The 530 - 1200 metre wide asteroid 2007 EP88 will make a close pass (55.5 lunar distances, 0.1427 AU), travelling at 30.03 km/second, to the Earth-Moon system on the 10th March, 2013 @ 21:53 UT ±00:01. See moreThe Lunar D...

Mapping the early history of the moon In 41st annual Killian Lecture, Maria Zuber describes looking deep into the moon's interior to chart its early history. For much of human history, the moon has been a familiar, yet remote, presence in the night sky. Only recently have humans been able to explore t...
Hubble Finds Appearances can be Deceptive Globular clusters are roughly spherical collections of extremely old stars, and around 150 of them are scattered around our galaxy. Hubble is one of the best telescopes for studying these, as its extremely high resolution lets astronomers see individu...
Did Vikings navigate by polarised light? A Viking legend tells of a glowing 'sunstone' that, when held up to the sky, revealed the position of the Sun even on a cloudy day. It sounds like magic, but scientists measuring the properties of light in the sky say that polarising crystals - which function in...

UV-transparent coating for image sensors Image sensors as used in cell phones are partially colour-blind. This is because of their coating, which prevents UV light from passing through. CMOS chips have as a result not been suitable for spectroscopy up to now. A new production process makes the coa...
