I recently visited the ALMA observatory in Chile. While I was poking around the telescopes, ALMA researchers released amazing new views of planet-forming disks around young stars.

These are the most detailed images yet of new solar systems being born.

By tuning in to different microwave frequencies, ALMA can create snapshots of different components of the disks that surround newborn stars.

For the first time, we can see the swirls and waves that turn clouds of gas and dust into worlds like our own.

Four faces of HD 135344B: the 12CO, 13CO, CS and continuum emission form this protoplanetary disk all show a complex morphology suggestive of a vortex.

In a related study, the ALMA observatory finds hints of planets being born around stars in our galaxy's "central molecular zone." This region is dense and turbulent, with a supermassive black hole at the center -- yet planets seem to be forming there anyway.

These amazing ALMA findings come from an international partnership with significant support from the National Science Foundation.

If you live in the U.S., please call your representatives to voice support for science funding across the board, from vital health to eye-opening exploration.

A 𑐴𑐶𑐟𑐶 (hiti) is an ancient Newah urban water feature: a stepped, sunken courtyard with waterspouts and a central pool. These are fed through a remarkable network of pipes, reservoirs, and irrigation systems drawing water from mountain springs dozens of kilometres away. Every day, hundreds of people from the neighbourhood come to draw water, bathe, and exchange news. They are a unique and precious feature of Newa urban architecture through which neighbourhoods are created.
