A grain of stardust extracted from the Murchison meteorite that landed in Victoria in 1969 was dated to roughly 7 billion years old, meaning it condensed in the atmosphere of a dying star more than 2 billion years before the Sun existed
1+ mon, 3+ day ago (552+ words) A silicon carbide grain extracted from the Murchison meteorite, which fell on a Victorian dairy farm in 1969, was dated in 2020 to about seven billion years old — condensed in the atmosphere of a dying star more than two billion years before…...
Saturn's moon Mimas looks like a dead, cratered rock — its surface is so inert that scientists assumed it was frozen solid — but in 2024 astronomers confirmed a global ocean hidden beneath the ice, formed just 5 to 15 million years ago
1+ mon, 6+ day ago (696+ words) Mimas looks frozen and geologically quiet, yet Cassini's measurements point to a young global ocean beneath 20 to 30 kilometres of ice. Published August 7, 2026 · How we edit Mimas does not look like an ocean world. It is small, cold and covered in…...
Mercury is shrinking — as its iron core slowly cools, the whole planet has contracted by up to seven kilometres, wrinkling its surface into cliffs hundreds of miles long
1+ mon, 3+ week ago (349+ words) Mercury carries the record of planetary cooling across its surface. Long, curving cliffs cut through craters and plains because the small planet lost internal...
Earth’s inner core is an iron-rich ball as hot as the surface of the Sun, kept solid only because the crushing pressure of the entire planet raises the temperature at which iron can melt
2+ mon, 20+ hour ago (686+ words) Earth's centre sounds like a contradiction. The inner core is hot enough to sit in the same temperature range as the visible surface of the Sun, yet it is not...
A rare meteorite examined in 2026 revealed evidence of a Moon-sized world that orbited the young Sun more than 4.5 billion years ago, then vanished — possibly shattered in a catastrophic collision while Earth was still being assembled
2+ mon, 1+ day ago (585+ words) A small stone from Northwest Africa has become evidence for a much larger absence. In a 2026 paper, researchers argue that the meteorite known as Northwest...
We have mapped the surface of Mars, the Moon and Venus in sharper detail than the floor of our own ocean, most of which no human instrument has ever seen up close
2+ mon, 5+ day ago (569+ words) Published July 8, 2026 Here is a claim that sounds like an exaggeration and is not: the best global maps of Mars, the Moon and Venus resolve finer detail than the best global map of the floor of our own ocean. The…...

New axis grid links complex earth data in space and time
7+ mon, 2+ day ago (187+ words) The representation separates space, time, and measured parameters into distinct axes, then aligns them in a unified grid that can accommodate a wide range of satellite and in situ measurements collected at different resolutions and times. By treating each dimension…...
