Two new minerals, never seen before in nature, have been recently discovered inside a meteorite.
The space rock was identified near the EI Ali district of Somalia in 2020, but locals have known of it for much longer. They call the stone Nightfall’ in folk songs and dances that go back seven generations. It is huge, weighing more than 15 tonnes, making it the ninth-largest meteorite ever discovered, and is predominantly made of iron and nickel.
Shortly after its discovery, a 70g slice was sent to Chris Herd at the University of Alberta for analysis. Herd soon noticed something unusual in the data, which was identified as a pair of new minerals.

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.
