*Discovery of a White Dwarf so massive it might collapse
Astronomers have discovered the most massive white dwarf ever seen. The smouldering cinder, which formed when two smaller white dwarfs merged, is packing a mass greater than that of our Sun squeezed into an object about the size of our Moon.
*A new hypothesis to explain Mercury’s huge iron core
A new study claims that rather than being the result of a massive collision blasting away much of its mantle – Mercury’s proportionally massive core is simply the result of where the planet formed.
*Planet Earth’s hot new neighbour
Astronomers have discovered a new exoplanet in our part of the galactic neighbourhood.
*A final mission for the Cygnus 15 cargo ship
A Cygnus cargo ship has undocked from the International Space Station to launch a series of five satellites before ending its mission.
*The Science Report
A new study shows people will need to vaccinate to at least 85% to achieve herd immunity.
Night-owls have an increasing risk of obesity.
Australia’s oddest and most critically endangered species of fungus.
China is continuing its preparations for war -- building over a hundred new nuclear missile silos.
Skeptic's guide to the Falcon Lake UFO incident.
