Studies suggest that the aluminium dust could accumulate between 10km and 30km above the Earth’s surface and heat the stratosphere and the layer of atmosphere above that, the mesosphere, by up to 1.5C over Antarctica. That in turn could lead to a weakening of the Antarctic polar vortex in the stratosphere, a key component of the climate, and possibly changing global wind patterns

I'm looking away from our world for a moment.

I'm looking at the little dot in this image.

It's a newborn planet, 5 times the mass of Jupiter, carving a path through the disk of dust around its star. This is the first time we've seen the process clearly.

We are watching a new planet come into the cosmos.

What appears to be a ripple in space, is today’s Picture of the Week depicting a newborn planet eating its way through its dusty cradle as it orbits its host star. This image, taken with ESO’s Very Large Telescope (VLT) in Chile, is the first clear detection of a baby planet in a disc with multiple rings. These so-called protoplanetary discs surround young stars and appear as disc-shaped structures of gas and dust, often with rings like the one in this image. They are the birthplace of planets, and the rings are thought to indicate the presence of (hungry) planets in the disc. Initially, little particles in the spinning disc begin to accumulate and grow as gravity takes over, stealing more material from the native disc until they evolve into embryo planets.

LIGO, facing threats of closure, more than doubles its black hole haul

LIGO's latest release provides us with our best-ever census of stellar mass black holes, more than doubling the known population.

Please, save these facilities from closing down!

After three test flights that fell short of the mark, #SpaceX put its #Starship super-rocket through a successful test mission that featured a first-of-its-kind payload deployment. Now I have this strange desire for a Pez candy dispenser. https://cosmiclog.com/2025/08/26/spacexs-starship-goes-the-distance-in-10th-test-flight/#Space

A very hungry planet! 🪐

That little dot is WISPIT 2b, a newborn exoplanet. About 5 times the mass of Jupiter, the planet is eating its way through its dusty cradle as it orbits the host star, a younger version of our Sun 🌞

Taken with ESO’s Very Large Telescope (VLT) in #Chile, this image is the first clear detection of a baby planet in a disc with multiple rings.

#PPOD: JWST has now captured images of all four gas giants in our solar system: Jupiter, Saturn, Uranus, and Neptune. These images are the first of their kind, and they offer a new and unprecedented view of these distant worlds.

The JWST's image of Jupiter is particularly stunning. The telescope's infrared vision allows us to see through Jupiter's thick clouds, revealing the planet's swirling atmosphere and its Great Red Spot. The planet's haze and auroras steal the show.

#space #science

Four images from JWST. Upper left: Jupiter in infrared, showing thick and thin cloud bands in white and blue. The Great Red Spot is white and near the four o'clock position. Upper right: Saturn in infrared, with bright rings and a dim planet. Lower left: Uranus in infrared, showing the bright rings and blue planet with a white glow in the middle. Lower right: Neptune in infrared, with faint bands, several tiny moons, and a gray-white planet with several bright spots that are storms.

An update on the world’s first cultural crop payload!

NASA’s SpaceX Crew-11 docked with the International Space Station on August 2, and the seeds had a brief stay in space, during which ISS astronauts photographed them.

Then on August 9, the seeds returned safely to Earth along with Crew-10. Jaguar Space CEO Luis Zea packaged them up for study after retrieving them from NASA.
