Starship Asterisk*

Are density waves a proven theory ? To me, they sound as nebulous as dark matter. :? There is no such thing as a proven theory. They cannot ever be proven, only disproven. Density wave theory is very widely accepted because it is modellable and the output of the models closely match observation. Th...

Embedded in the link “ embedded in the molecular cloud ” was the statement “…We also identify the filamentary structure of Perseus and discuss the relation between filaments and star formation, confirming that stars form preferentially in filaments…”. That I find a curiosity of unprecedented magnitu...

My first thoughts revolved around how many stars and planets does an area of the size and density of the Cone Nebula represent? The nebular hypothesis speaks to the process why these clouds form components, and are essential in the universe for the star and planet accretion, but is how many may even...

Cosmic ray spallation is listed as sources of beryllium and boron but lithium is also referred to in some articles . Thinking big , could we someday make these in a lab? How could we test if lithium could be artificially produced to increase our supply :?: Or might that take three infinities(888)? ...

Not often it's clear this time of year but tonight's full moon, I'd cheer!

Building on lessons learned, Lucy will carry on exploring the making of our solar system and perhaps view our home planet from afar.

And we'll get a view from inside a real trojan horse.

Who says nothing travels faster than light? Through animation you could go anywhere , as fast as you want. Might need a pretty big computer but the sky isn’t the limit. From the comfort of your living room, I could see ever larger data sets enabling your virtual ship to sail anywhere your imaginatio...

I like this 3D representation. JWST will be the next horse whisp-erer.

Ever wonder how much a bubble weighs? Let alone our bubble.

If you can figure that out - you should get the pot of gold.

What I'd like to see is a three dimensional portrait of the galaxy and relative directional motion of it's different areas. The reddish dust lanes, if that's correct, leading toward the center appear to be rising up from the plane and returning toward the center. Just saying it has an appearance of...

Next generation lunar rovers are proposed to be duct tape free. Though some of the planning still require basic materials. Give them a try. :thumb_up: Unless they offer Apple CarPlay, that's a hard pass for me! Bojo was curious about “Robby the Robot” but we’d willing to submit our contribution tow...

:yes: Had there ever been a guest white dwarf in Earth's sky? Not in the human history Hi Victor. Your question made me curious. They're not visible to the naked eye but there are a few examples . For white dwarfs, we'd all need some help. :shock: Now if there were dark stars , good luck on that. we...

Its stars aren't from dust in the wind?

That " inside a single proton " link to the Quanta Magazine article is quite enlightening about the complexity present in every single proton (and neutron I presume). Who says things become simpler the smaller you look?! Having driven over SLAC’s accelerator while our family was visiting ...

I too struggle to see this effect so I hope Chris's technique will help. But Mars will be disappearing later this week right before your eyes.

Take a peek.

Do you suppose Occam’s Razor might be imposed for the unknowns of the universe? We’ve searched for very complex theories but which one is the simplest ? To me, the easiest to believe has to include, “What function do the unknowns provide for the state of the universe to exist?” A Yin and Yang appro...

If supernovas trigger star formation, Gum wasn’t our mother.

Which one was is shaping new science.

Bending light produces mind-bending opportunities. From Terrascopes to gravity scopes.

The possibilities are supernumerary!

Beautiful Saturn! Will Dragonfly solve some of Titans mysteries?

Possibly Orin and this may be one of them.

I couldn't even find it in " Molecule of the Week"

Zooming in, we see a galaxy similar to our own but with some distinct differences.

I wonder if the cloudy sections in the core would resemble the nebulas - making ours "milky"

Beautiful complexity. Torus structure in the life and death of stars seems to tell us something about the universe.
