It will rise significantly. The damage is widespread. USGS also forecasts that much larger figures of casualties are likely: earthquake.usgs.gov/earthquakes/...

Cranes seemingly holding tight the #conjunction of Venus and Jupiter in the twilight of today's sunset at Zaragoza (Spain). #science #astronomy 🧪🔭

Venus (middle left) and Jupiter (near the bottom left) are seen as bright stars in today’s sunset, shining through thin, pastel-colored, cirrus clouds.

In the foreground, there are three cranes in different poses, at the construction site of the new public football (soccer) stadium of Zaragoza, the fifth largest city in Spain.

The photographer (Álvaro González) searched for a vantage point to take the picture such as the extremes of two cranes seem to almost touch each of the planets, respectively.

Waving back at #Artemis minutes after its astronauts watched the #Earthrise and saluted us. This is almost the opposite view of the Moon to the one they were seeing. From Barcelona, Spain 👋🏻 🔭🧪

The Moon seen just after the Artemis II spacecraft watched the earthrise and regained contact with us.

From my location in the Universe, the Moon was rising over the horizon, so its light traversed a long stretch of Earth’s atmosphere.

Because of that, Earth’s atmospheric light absoption gave the Moon image an orange hue. And atmospheric turbulence caused image distorsions, most evident along the Moon’s limb.

Anticyclone afternoon at the Mediterranean shore near Barcelona, Spain. No clouds, just gold over a velvet of blue.

A calm landscape by the Mediterranean Sea, with rocks in the foreground, small irregular waves on a dark blue water, and a golden sunset.

Reflection of the golden sun on small, irregular waves by the sea shore, in a calm sunset.

Tonight’s full Moon.

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! #Science #Astronomy 🧪🔭

A cumulonimbus cloud illuminated by the last sun rays of today. With pileus (a cap cloud) on top. Seen as I drove through the Monegros Desert (Spain).

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).

A wide view of stars and nebulae of the Milky Way covering the constellations of Aquila, Scutum, Sagitta, Delphinus, among others. Five-second exposure with my phone, from the very dark skies of La Rioja Biosphere Reserve (Spain). #science #astronomy 🔭

View of a myriad of stars, surrounded by nebulae.

Processed to enhance contrast and saturate the colors (reddish from ionized hydrogen, greenish from ionized oxygen).

I just became associate editor at Journal of Seismology: link.springer.com/journal/1095... Possibly I will handle your manuscript if it deals with: - statistical seismology, - earthquake catalogues, - probabilistic earthquake forecasting, - seismic hazard or - earthquake geology. #science 🧪 ⚒️

Partial solar eclipse at its maximum from Zaragoza, Spain, today at 10:40 UTC. A sunspot can be seen near the Sun's limb (the border of the disk). #Astronomy 🔭 #Science 🧪

Partial solar eclipse, with the Sun’s disk covered in approximately a 25% by the Moon, so with a shape similar to an apple with a large bite. A sunspot can be seen near the border of the Sun’s disk.

Weather permitting, do not miss Venus next to the sliver of the Moon this sunset. Picture from five minutes ago, from Spain. #Astronomy 🧪🔭

Venus next to the thin, crescent Moon in today’s sunset.

And this is my best shot of tonight’s full Moon alone.

Tonight’s full Moon, with many surface details visible.

Mars (small, dim, redish dot below) and the full Moon. Single pic taken from Barcelona, Spain, at 22:00 UT. It is difficult to capture Mars properly without overexposing the Moon. Tonight’s occultation of Mars will not be visible from here.

The Moon and Mars as seen tonight in the sky, relatively close to each other.
