““Many adults are put off when youngsters pose scientific questions. Children ask why the sun is yellow, or what a dream is, or how deep you can dig a hole, or when is the world’s birthday, or why we have toes. Too many teachers and parents answer with irritation or ridicule, or quickly move on to something else. Why adults should pretend to omniscience before a five-year-old, I can’t for the life of me understand. What’s wrong with admitting that you don’t know? Children soon recognize that somehow this kind of question annoys many adults. A few more experiences like this, and another child has been lost to science. There are many better responses. If we have an idea of the answer, we could try to explain. If we don’t, we could go to the encyclopedia or the library. Or we might say to the child: “I don’t know the answer. Maybe no one knows. Maybe when you grow up, you’ll be the first to find out.”” — Carl Sagan, The Demon-Haunted World: Science as the Candle in The Dark”
Love can be explained by science - even though each of us have our own experiences and stories that can never be adequately quantified.
Resembling an aerial fireworks explosion, this dramatic picture of the energetic star WR124 reveals it is surrounded by hot clumps of gas being ejected into space at speeds of over 100,000 miles per hour. Also remarkable are vast arcs of glowing gas around the star, which are resolved into filamentary, chaotic substructures, yet with no overall global shell structure.
The massive, hot central star is known as a Wolf-Rayet star. This extremely rare and short-lived class of super-hot star (in this case 50,000 degrees Kelvin) is going through a violent, transitional phase characterized by the fierce ejection of mass. The blobs may result from the furious stellar wind that does not flow smoothly into space but has instabilities which make it clumpy.The surrounding nebula is estimated to be no older than 10,000 years, which means that it is so young it has not yet slammed into the gasses comprising the surrounding interstellar medium.
“Every one of us is, in the cosmic perspective, precious. If a human disagrees with you, let him live. In a hundred billion galaxies, you will not find another.”
- Carl Sagan (Cosmos)
Great educational video that every adult and child should watch. Excellent teacher resource.
Happy New Year!

Although intelligence is important, it is even better to be kind. Intelligence without empathy is nothing but wasted talent and a downward spiral for humanity.
Every atom in your body came from a star that exploded. You are quite literally a child of the stars :)
From the movie Contact (1997) Starring Jodie Foster. Written by Carl Sagan.
Just a little reminder from the great Sagan.
