During the Solar System’s first million years, its earliest outer worlds formed from material that was up to 92 percent heat-forged rock, while gas flowing through the young system filtered out much of the surrounding ice-rich dust.

Los primeros mundos sólidos ensamblados en el Sistema Solar exterior no se limitaron a recopilar una primicia representativa de todo lo que les rodeaba. Un nuevo análisis de meteoritos de hierro carbonoso indica que sus planetesimales originales contenían sólo entre un 8 y un 17 por ciento de una matriz fina y rica en volátiles. … Read more

Reef fish on a Curaçao coral patch never bolted from a black disk expanding on an iPad below two metres a second, and that threshold sits just under the speeds at which bar jacks on the same reef were filmed attacking

Peeking is the word for what an approaching object does to an eye. The image of the thing grows, and grows at an accelerated rate, and that rate carries information: how fast the object is coming and approximately when it will arrive. Animals across the tree of life respond to it, from insects to birds … Read more

Russian Progress spacecraft delivers 3 tons of cargo to the ISS (video)

Russian Progress spacecraft delivers 3 tons of cargo to the ISS (video)

The Russian Progress 96 robotic cargo spacecraft rendezvoused with the space station today (September 19). Progress 96 launched atop a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan on Wednesday (September 16), kicking off a three-day orbital chase of the International Space Station (ISS). That chase came to an end today at 9:44 a.m. EDT … Read more

On Deimos, orbital speed just above the surface is only about 14 km/h—around elite racewalking pace—while roughly 20 km/h would let you escape the tiny moon altogether.

On Deimos, orbital speed just above the surface is only about 14 km/h—around elite racewalking pace—while roughly 20 km/h would let you escape the tiny moon altogether.

On Earth, orbit belongs to the realm of rockets. The International Space Station travels at approximately 28,000 kilometers per hour, and a projectile would need about 40,000 kilometers per hour near the Earth’s surface to escape without further propulsion. Around Deimos, Mars’ smallest moon, the same physics produces street-level numbers. A 2024 peer-reviewed study of … Read more

Ancient rocks from Western Australia suggest Earth was already dragging surface water into its mantle and using it to generate volcanoes 3.1 billion years ago — through a primitive recycling process that may have preceded modern plate tectonics

Ancient rocks from Western Australia suggest Earth was already dragging surface water into its mantle and using it to generate volcanoes 3.1 billion years ago — through a primitive recycling process that may have preceded modern plate tectonics

The pillow lavas look like a bunch of stone beanbags, collapsed one on top of the other where the molten rock collided with cold seawater and hardened on the spot. Those on display in a stretch of the Pilbara in Western Australia have remained there, largely undisturbed, since long before anything on this planet had … Read more

Citizen scientists revived NASA’s long-retired ISEE-3 probe in 2014 and fired its thrusters for the first time in 27 years, restoring its spin—but the larger burn meant to return it to an Earth–Sun observation point failed because the nitrogen needed to pressurize its fuel system had apparently run out.

Citizen scientists revived NASA’s long-retired ISEE-3 probe in 2014 and fired its thrusters for the first time in 27 years, restoring its spin—but the larger burn meant to return it to an Earth–Sun observation point failed because the nitrogen needed to pressurize its fuel system had apparently run out.

In 2014, a spacecraft launched before the first space shuttle flight was approaching Earth for the first time in decades. NASA had ended support for ISEE-3 in 1997. The specialized ground equipment once used to command it had been scrapped and no agency-funded mission was waiting to take over. A publicly funded group of independent … Read more

On the dwarf planet Ceres, a lone mountain called Ahuna Mons rises four kilometres from an otherwise flat, cratered plain, built not from lava but from erupting salty brine that froze solid.

On the dwarf planet Ceres, a lone mountain called Ahuna Mons rises four kilometres from an otherwise flat, cratered plain, built not from lava but from erupting salty brine that froze solid.

Ceres is a low-relief world. Its charcoal-gray surface is riddled with impact scars, but between the craters much of the terrain rolls gently across the dwarf planet. Then a mountain breaks the pattern. Ahuna Mons rises about four kilometers above the plain and stands alone rather than joining a range or forming the central peak … Read more
