Message to Mercury

Of all the planets of the inner Solar System, Mercury is the least-visited. No mission has ever landed on its surface, only two missions have studied it from space, and only one of those has reached orbit.

What's the charge?

When metal objects are given an electric charge, the charge is not evenly spread through it. It collects on the surface, and in particular on parts of the surface which are curved. More...

Swift keeps flying

Every two years, NASA carries out a major review of its science missions to decide which to continue supporting. This year's review brought good news for the Swift mission - a satellite which surveys highly energetic cosmic phenomena, such as gamma ray bursts. Swift was ranked first, meaning it is guaranteed to get continued funding and support until 2016 and, subject to a further review, could continue to 2018.
One of the instruments on board Swift is the Ultraviolet and Optical Telescope (UVOT), a two-metre long telescope assembly rigged up to a camera system which can take pictures in visible and ultraviolet light. The telescope assembly was built by UCL's Mullard Space Science Laboratory.

The Tadpole Nebula

The vast majority of the stuff of the universe is hydrogen. Unlike the heavier elements, which were synthesized in supernova explosions, the universe's hydrogen was produced in vast quantities in the Big Bang. While it is the heavier elements that make the complex chemistry of the universe possible, it is hydrogen that forms stars, and gives us the light, heat and energy we need to live. More...

A colour camera for the Red Planet

Europe's ExoMars rover, scheduled to land on Mars in 2018, will feature a main camera system known as PanCam, which will contain two wide-angle cameras and one narrow-angle (telephoto) camera. The PanCam project is led by Prof Andrew Coates at UCL's Mullard Space Science Laboratory. More...
