This is another great result from ALMA! That to ALMA’s exceptional spatial resolution, and spectral resolution, astronomers have found rings, gaps, and cavities in extremely compact disks around young stars. These observations show that planet-formation […] [Original post on mathstodon.xyz]

ALMA images of the 11 compact planet-forming disks observed in the Lupus star-forming region. Using the highest angular resolution available with ALMA at a wavelength of about 0.9 millimeters, astronomers revealed previously hidden structures in several of these small disks. The lower-right panel shows the orbits of Earth, Mars, Jupiter, and Saturn, together with the asteroid belt, for scale. The comparison illustrates how these observations probe planet formation at distances comparable to those within our own Solar System. Each white scale bar represents two astronomical units; one astronomical unit is the average distance between Earth and the Sun. Credit: P. Curone et al. – ALMA

#SilentSunday

A wooden sunrise, set into the pediment of a building enclosing the carousel at Henry Vilas Zoo.

The pediment is dark green, while the sun is yellow and the rays are various shades from yellow to red.

The sun is also just barely peeking over the roof.

Slow onwards and upwards #snail #caracol #dots #DottedLine

This image shows a snail with a dark, patterned shell moving slowly across a rough, gray tarmac surface, right next to the edge of a curb. The path goes from the bottom left corner to the top right corner.

Follow the dotted line at snail pace / Sigue la línea de puntos a paso de caracol

This image features a snail with a brown and yellow patterned shell on a rough, textured asphalt surface, next to a light-colored wall. There is a trail of small, dark, wet-looking spots leading and fading as they are further away from the snail. The trail starts on the bottom left corner, goes up, then a bit in diagonal, and then swerves at the last part up and to the left, but still arrives to the top left corner.

My sister in law came up to the cabin this week to see the fall colors. The weather was mostly cold and windy until today so she was able to get the money shot early this morning when the lake was as smooth as glass.

Chilean national holidays, “Fiestas Patrias”. #GoldenHour #PhoneCamera #Andes #Santiago #LasCondes #Chile #FiestasPatrias

Nearest peaks of the Andes in Las Condes with snow caps in the background, illuminated by sunset golden light. In the foreground, there is a Chilean flag waving on a pole, with some trees and a street light visible nearby.
