Studying our cosmic neighbourhood from 'outside' is an eye-opener

Looking at home from afar

Travel is all very well, but sometimes you can learn more by staying close to home. As astronomers get excited by the views of distant galaxies provided by JWST, it's good to be reminded that we can benefit from paying close attention to our surroundings.

Some of the most exciting areas of research happening at the moment consider our local galaxies as if they were observed from a distance, something that can be done thanks to extensive surveys of stars in the Milky Way and deep imaging of other members of our Local Group of galaxies. Considering our own home in this way allows us to test the accuracy of techniques used to study the distant Universe - though in the case of the Milky Way, living in our object of study does make things slightly more complicated at times.

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.
