Scientists examining samples returned from asteroid Bennu found ribose and glucose inside — and with phosphate and every RNA nucleobase already detected in the same asteroid material, every chemical component needed to build RNA was present in the early solar system, long before life existed on Earth.
The Bennu sample is becoming less like a single asteroid story and more like a chemistry inventory from…

Earth’s inner core is not rock but a sphere of solid iron-rich metal, smaller than the Moon yet probably more massive. As the planet gradually loses heat, liquid metal freezes onto its surface, expanding it by roughly a millimetre each year.
The centre of Earth is easy to imagine wrongly. It is not a cavern, not a furnace of…
In 2026, the FCC authorized radio operations for Reflect Orbital’s first 18-metre space mirror, a single demonstration for a proposed 50,000-satellite system that one astronomy model says could raise the natural night-sky background by 200% to 300% – Space Daily

A red dwarf star called TRAPPIST-1, just 40 light-years from Earth, hosts seven Earth-sized planets — including three orbiting in the narrow zone where liquid water could potentially survive
TRAPPIST-1 is not impressive by the usual standards of stargazing. It is too faint to see with the…
The Sun ejects roughly a billion tons of charged plasma in a single coronal mass ejection — and it can cross 150 million kilometers to Earth in under 18 hours
A coronal mass ejection is the Sun throwing a piece of itself at the rest of the solar…

An asteroid struck somewhere north of Australia 11 million years ago, scattering molten glass across a 900-kilometre ellipse in South Australia — yet scientists still cannot find the crater it left behind
The glass is small enough to sit in a museum drawer, but the event it points to was…
