Great!

I will use it in my next freshman Physics lesson.

Dark blue cloud cover with swirls.

And here is the view of the same cloud from below, chased by car as the sky got darker…

The swirls are formed by vigorous, ascending currents of convecting air.

You will be able to see many pictures of today’s #eclipse, but not so many with a bird transiting in front.

The Earth, a fellow earthling and the Moon in a row.

And yes, a window among the clouds finally opened after leaving behind the cumulonimbus of the previous post!

A menacing storm cloud, with the contrast and shadows enhanced by the side illumination. It has the typical broccoli-like texture of this kind of cloud (a cumulonimbus), but it also displays a lens-like, horizontal, cap cloud on top (technically called a pileus).

With pileus (a cap cloud) on top.

A close up view of smoke plumes in the Spanish region near Ourense where several wildfires are active. This is a satellite image from Sentinel-2 - we can see land in brown and green with thick smoke plumes.

A sentinel-3 satellite image of the Iberian Peninsula. some clouds can be seen in north but the main feature of this image are the many smoke plumes from the current ongoing wildfires affecting the region.

On X, Masaki Nobushiro posts a recurring (and useful) drawing about how people wrongly think a 1m tsunami is a cresting wave when it's actually a wall of water filled with dangerous and deadly debris that's strong enough to sweep up a car.

🔥 Today’s satellite view shows smoke rising from multiple wildfires burning in Portugal and Spain.

Smoke is often more intense in the late afternoon when high temperatures, low humidity, and strong winds cause wildfires to burn more aggressively.

A top-down view of a spiral galaxy, showing its brightly shining centre, its broad spiral arms and the faint halo around its disc, as well as distant galaxies and stars on a dark background. Large blue clouds of gas speckled with small stars and strands of dark dust swirl around the galaxy’s disc. A couple of the background galaxies are large enough that their own swirling spiral arms can be seen.

Hubble has observed this galaxy several times to study two supernova blasts and their aftermath, uncovering a 'zombie' star

Working on a project and made this image of the Hunga Tonga volcanic eruption.

Never seen it from this perspective and it sort of blew my mind.

Night sky inder different light pollution regimes. Inner city sky is grey and dull, while the "excellent dark sky site" is deep dark with a lot of stars visible

Just a reminder to writers, pressure waves travel about ten times faster in rock than in air. So first, the ground will shake, then the blast wave hits.

A komatiite analog to potential ultramafic materials on Io Ultramafic volcanism is one model which fits currently available data for some eruptions on Jupiter's moon, Io. Assuming that such activity does occur, it is possible to apply komatiitic analogs and ...

Io, the volcanic moon of Jupiter, still nowadays has some very high-temperature eruptions.

It has been proposed that they could have komatiitic composition:

You are more than welcome. 🙂

You, with your research, are deciphering the language of the Earth in ways the rest of us cannot do.

We need your voice to be heard.

We need you to tell us.

And the Earth needs you to tell us.

In this endeavor, you are not alone.

Do not hesitate to reach out. 😌

How 3M Discovered, Then Concealed, the Dangers of Forever Chemicals The company found its own toxic compounds in human blood—and kept selling them.

How did 3M’s “forever chemicals” end up in all of us? Sharon Lerner reports the inside story of the corporate scientists who discovered—then helped to conceal—the dangers of its chemicals.

Getting the PhD should not be so challenging, but unfortunately it sometimes is (or was, in my case).

Let me know if I could be of help. I have volunteered as AGU mentor and helped other PhD candidates overcome difficulties.

Even just feeling heard and supported may help.

All my best wishes!
