Over recent years, the low-light imaging capabilities of smartphones have improved greatly. It's also encouraging to see manufacturers actively promoting phones based on their performance under low-light conditions. Not all smartphones are created equal of course, and older models may still struggle to grab anything out of the darkness. This is also true of current models, not all of which put a priority on low-light capability.
For those brands which offer good night-time sensitivity, the cameras found on their phones are quite capable of imaging atmospheric phenomena such as the aurora or our 'Capture' subject for this month, noctilucent clouds (NLCs). If present, NLCs can vary in brightness from just about visible to making you wonder how anyone can ever miss them. Bright displays may register using the automatic functions in your phone's camera, while dimmer ones may need a bit of fiddling to get something recorded.
Many smartphones have advanced photographic modes, offered under a 'Pro' setting. These allow you to tweak the camera's settings, adjusting core values such as ISO, exposure time, and white balance. In addition, there are apps available which may offer a better low-light settings interface.
The technology in some phones is truly remarkable, offering processes such as dynamic image-stacking as standard. Here, you can take a multi-second exposure of a low-light scene while the camera is handheld, and the final result is free of hand-shake.

Could We Find Aliens by Looking for Their Solar Panels?- Designed to reflect ultraviolet and infrared, the panels have a unique fingerprint
Researchers searching for life beyond Earth spend a lot of time thinking about what telltale signs might be detectable astronomically. Forms of unambiguous evidence for the presence of life on another world are known as biosignatures. By extension, techno signatures are indicators of activity by intelligent, civilisation-building life.
Antimatter- In our continuing series, Govert Schilling looks at antimatter, the strange counterpart to most of the matter filling our Universe
Particles and corresponding antiparticles are very much alike, except they have opposite electrical charges. For instance, the antiparticle of the electron - known as the positron - has the same tiny mass, but while electrons carry a negative electrical charge, positrons are positively charged.
Where Have All The Milky Way's Early Stars Gone?- Our Galaxy has a curious lack of pristine stars
The Big Bang produced a Universe filled almost exclusively with hydrogen and helium; all other elements - what astronomers call metals - were produced by stars, supernovae and everything that happens later. So if you can pick out a pristine star with no metals polluting it from among the billions in the Milky Way, then you are likely to have a star dating from our Galaxy's earliest days.
