Sedimentary deposit. Gemstones, quartz etc washed out of host rock and deposited downstream.

Windless evening in Eastern Australia, Renewables down to 8%, big batteries at maximum output, an hour or so capability remaining. Renewable energy sucks.

When Perseverance was traversing around the delta in Jezero crater the images were captivating. Now outside the crater the terrain may be scientifically interesting but the images are somewhat boring.

Oh for goodness sakes. Hamas won the 2006 Palestinian legislative elections and assumed administrative control of Gaza Strip. Got that. The people of Gaza, Palestinians, voted a terrorist group into power. Hostages? Israel handed the Gaza Strip to Palestinians who then embraced terrorism.

For the first time, a research team observed a violent interaction between two distant galaxies, revealing how one of the two, equipped with a quasar, hits the other with powerful radiation, limiting its star formation and fueling the black hole.

A really benign environment, slow and gentle erosion and you can end up with some pretty weird results.

One of the more intriguing images from Curiosity rover climbing the foothills of Mount Sharp in Gale crater. Just elemental Sulphur but how it formed in a sedimentary environment in this area is a bit of a head scratcher. Mars is full of surprises.

Another lovely evening in Australia and despite the massive investment and subsidies poured into renewables by our feckless socialist Labor government they are providing just 6% of power demand. Reality trumps ideology and propaganda every time.

A clumpy galaxy, observed with the Hubble Space Telescope in the COSMOS survey.

It is at redshift 0.61 (lookback time 5.96 billion years) with coordinates (149.77834, 1.95285).

44 volunteers classified this galaxy in Galaxy Zoo: Hubble.

The cause of the Martian dichotomy has been controversial but seismic results from NASA's InSight lander indicate that this was endogenic, not impact. The discovery of gneiss by Perseverance rover at Jezero crater supports tectonic plate activity.

This amazing view of Sharpless 29 reveals the intricate dance of light and matter, as gas and dust clouds respond to the glow of stars forming within the nebula.

The world is watching the US in total bewilderment.
Ian Fleming was prescient in the book 'For Your Eyes Only' where James Bond stated “It’s to the effect that America has progressed from infancy to senility without having passed through a period of maturity.”

Why are so many Americans complaining? In a democracy you get the government you deserve. True it is bewildering to other countries that an unelected , South African multi, multi billionaire seems to be in control but hey, that's apparently what the majority of States voted for.

America bewilders me. A multi, multi billionaire oligarch is handed control of a new department of government efficiency with sweeping authority and seemingly has control over treasury matters. Yet that oligarch's companies have government contracts. Conflict of interest writ clear.

I don't know if humans will ever stand on Mars but the images sent back from the four rovers over the past two decades have been stunning.
