Comet C/2023 A3 Zijinshan–ATLAS ☄️

Captured during its spectacular passage through the inner Solar System in October 2024.

Closest approach to Earth: 12 October 2024, about 70 million km away.

A male Indian paradise flycatcher returns to its nest in the rain.

Its extraordinary white tail streamers can grow longer than the bird’s body, one of the most distinctive sights in an Asian forest.

The ocean never runs out of impressive surprises. 🌊

A reef is never still.

Coral reefs are busy ecosystems packed with fish, corals and other marine life, all sharing the same small stretch of ocean.

White tigers aren’t albinos.

Their white coat is caused by a rare recessive genetic variant. A cub must inherit it from both parents for the colouring to appear, which is why the trait is so uncommon in nature.

Bigfin squid (Magnapinna sp.) are among the deep ocean’s strangest sights. Their arms and tentacles trail into extraordinarily long filaments, and encounters are rare.

The first confirmed footage of a living colossal squid in its natural habitat. 🦑

ROV SuBastian filmed this juvenile about 600 metres deep near the South Sandwich Islands.

The solar storm that missed Earth.

In July 2012, an enormous CME erupted from the Sun and crossed Earth’s orbit. but our planet wasn’t there when it arrived.

NASA spacecraft captured the event from several viewpoints.

@GBCNewsroom Typical reaction from certain humans, reach for a shotgun and cause harm and misery. Aren’t we such a wonderful species.

Orcas are powerful, intelligent animals that deserve respect.

Whatever anyone thinks of their interactions with boats, the suspected shooting of Toñi in the Strait of Gibraltar was a cowardly act, to say the least.

From Goddard to Kennedy Space Center. NASA’s Roman Space Telescope is almost ready for space. 🔭

Launching August 30 aboard Falcon Heavy, Roman will survey vast areas of the infrared universe and hunt for distant worlds.

A worrying development in the Strait of Gibraltar.

Toñi, one of the best known Iberian orcas linked to boat interactions, has been seen with wounds suspected to have been caused by gunfire. Spanish authorities are investigating.

Polar bears are built for extreme cold, so well insulated that overheating can actually be a problem when they run.

Two layers of fur and a thick layer of fat help them survive the Arctic, but they also make shedding heat difficult.

Black holes are wild. 🕳️

Their gravity warps spacetime so strongly that beyond the event horizon, even light cannot escape.

A superb visual explanation from NASA Goddard.

Ivy Mike, 1952.

The first full scale thermonuclear test produced a 10.4 megaton explosion. The experimental device used cryogenic liquid deuterium and was far too large to be a practical bomb.

The island of Elugelab was vaporised.

Why does the sky glow green over Iceland? 🌌

Charged particles from the Sun are guided by Earth’s magnetic field into the upper atmosphere, where collisions with oxygen produce much of the aurora’s green light.

The far side of the Moon isn’t permanently dark. 🌒

The Moon is tidally locked to Earth, so we normally see the same hemisphere. But sunlight still reaches both sides as the Moon orbits us, meaning the far side has phases too.
