24 December: Opposition of Mars
Mars will be easy to see throughout the month, but is at its best in the weeks on either side of 24 December.
On that date the planet will be in line with the Earth and Sun and from the ground will appear to be opposite the Sun in the sky (at opposition).
This year Mars remains fairly distant from Earth and never comes closer to us than 88 million km (or 55 million miles) but at opposition it will still appear to be brighter than all the other objects in the sky, apart from the Sun, Moon, Venus and Jupiter.
Around midnight, Mars will be high in the south, when it will be an unmistakeable sight to observers in the UK. The planet will look like a bright red dot, located in front of the stars of the constellation of Gemini and above the more familiar grouping of Orion. With moderate-sized telescopes, careful observers should be able to see hints of dusky markings on the Martian surface.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
