Hey there friends! 🌇
We wish you a very warm welcome back to Wellness Wednesdays. We are deep deep into December now. So far, in fact, we now find ourselves on the longest day of the year itself. That’s it! We made it! Or, more importantly, you made it! Great work, folks.
We are making our way through the winter, one day at a time. Why not mark the occasion with a little help from the lovely people at @kokobot. They are here as ever with their unique brand well-being assistance. Their mental health experts specialize in helping people find the techniques and tools needed to take the utmost care of mental and emotional well-being
☮️ And with it, they have improved the lives of millions of people around the world. If that sounds good to you, it certainly sounds good to them—they would love to help you too! Why not start off with this fantastic mood-boosting interactive quiz? It’s the season of giving, after all, so consider it your first present of the year 🎁. We are just days from Christmas, and for those who don’t celebrate, we hope you are enjoying the festivities and beautiful winter weather.
As for Koko, it is a nonprofit that provides mental health technologies for large-scale social networks.
If you’re struggling through these longer days, why not click here to start an anonymous chat with kokobot, access further resources, or share what’s on your mind?
Don't like quizzes? Music, more your vibe? We have got just the thing you need. Enjoy a warm plate of soul food with this perfect feel-good playlist just for you.🎶
This is it, people. The longest day, and then it’s only ever brighter from here. 🌅

Stellar Winds
Stellar winds are fast moving flows of material (protons, electrons and atoms of heavier metals) that are ejected from stars. These winds are characterised by a continuous outflow of material moving at speeds anywhere between 20 and 2,000 km/s.
In the case of the Sun, the wind ‘blows’ at a speed of 200 to 300 km/s from quiet regions, and 700 km/s from coronal holes and active regions.
The causes, ejection rates and speeds of stellar winds vary with the mass of the star. In relatively cool, low-mass stars such as the Sun, the wind is caused by the extremely high temperature (millions of degrees Kelvin) of the corona.
his high temperature is thought to be the result of interactions between magnetic fields at the star’s surface, and gives the coronal gas sufficient energy to escape the gravitational attraction of the star as a wind. Stars of this type eject only a tiny fraction of their mass per year as a stellar wind (for example, only 1 part in 1014 of the Sun’s mass is ejected in this way each year), but this still represents losses of millions of tonnes of material each second. Even over their entire lifetime, stars like our Sun lose only a tiny fraction of 1% of their mass through stellar winds.
In contrast, hot, massive stars can produce stellar winds a billion times stronger than those of low-mass stars. Over their short lifetimes, they can eject many solar masses (perhaps up to 50% of their initial mass) of material in the form of 2,000 km/sec winds.
These stellar winds are driven directly by the radiation pressure from photons escaping the star. In some cases, high-mass stars can eject virtually all of their outer envelopes in winds. The result is a Wolf-Rayet star.
Stellar winds play an important part in the chemical evolution of the Universe, as they carry dust and metals back into the interstellar medium where they will be incorporated into the next generation of stars.

A protoplanetary disk is a rotating circumstellar disk of dense gas and dust surrounding a young newly formed star, a T Tauri star, or Herbig Ae/Be star. The protoplanetary disk may also be considered an accretion disk for the star itself, because gases or other material may be falling from the inner edge of the disk onto the surface of the star. This process should not be confused with the accretion process thought to build up the planets themselves. Externally illuminated photo-evaporating protoplanetary disks are called proplyds.
The nebular hypothesis of solar system formation describes how protoplanetary disks are thought to evolve into planetary systems. Electrostatic and gravitational interactions may cause the dust and ice grains in the disk to accrete into planetesimals. This process competes against the stellar wind, which drives the gas out of the system, and gravity (accretion), which pulls material into the central T Tauri star.
