All monster black holes are not equal. Watch this video to see how they compare to each other and to our solar system. The black holes shown, which range from 100,000 to more than 60 billion times our Sun’s mass, are scaled according to the sizes of their shadows – a circular zone about twice the size of their event horizons. Only one of these colossal objects resides in our own galaxy, and it lies 26,000 light-years away. Smaller black holes are shown in bluish colors because their gas is expected to be hotter than that orbiting larger ones. Scientists think all of these objects shine most intensely in ultraviolet light.

Since 2015, scientists with NASA’s Arctic Boreal Vulnerability Experiment (ABoVE) project have been studying how climate change is affecting Arctic and boreal regions. The team is studying permafrost thaw, changes in plant cover, wildfires, shifting animal migration patterns and more. With research aircraft flying over Alaska and northwestern Canada and scientists conducting field experiments on the ground below, ABoVE is collecting data that will help researchers understand how these events are intertwined – and how they are impacted by climate change.

#RuthB #Dandelions #Lyrics 🎤 Lyrics: Ruth B. - Dandelions [Verse 1] Maybe it's the way you say my name Maybe it's the way you play your game But it's so good, I've never known anybody like you But it's so good, I've never dreamed of nobody like you [Pre-Chorus] And I've heard of a love that comes once in a lifetime And I'm pretty sure that you are that love of mine [Chorus] 'Cause I'm in a field of dandelions Wishing on every one that you'd be mine, mine And I see forever in your eyes I feel okay when I see you smile, smile [Post-Chorus] Wishing on dandelions all of the time Praying to God that one day you'll be mine Wishing on dandelions all of the time, all of the time [Verse 2] I think that you are the one for me Cause it gets so hard to breathe When you're looking at me I've never felt so alive and free When you're looking at me I've never felt so happy [Pre-Chorus] And I've heard of a love that comes once in a lifetime And I'm pretty sure that you are that love of mine [Chorus] Cause I'm in a field of dandelions Wishing on every one that you'd be mine, mine And I see forever in your eyes I feel okay when I see you smile, smile [Post-Chorus] Wishing on dandelions all of the time Praying to God that one day you'll be mine Wishing on dandelions all of the time, all of the time [Bridge] Dandelion into the wind you go Won't you let my darling know? Dandelion into the wind you go Won't you let my darling know that [Chorus] I'm in a field of dandelions Wishing on every one that you'd be mine, mine And I see forever in your eyes I feel okay when I see you smile, smile [Post-Chorus] Wishing on dandelions all of the time Praying to God that one day you'll be mine Wishing on dandelions all of the time, all of the time [Outro] I'm in a field of dandelions Wishing on every one that you'd be mine, mine

Comparison of human hair to different smaller objects

A new model is bringing scientists a step closer to understanding the kinds of light signals produced when two supermassive black holes, which are millions to billions of times the mass of the Sun, spiral toward a collision. For the first time, a new computer simulation that fully incorporates the physical effects of Einstein’s general theory of relativity shows that gas in such systems will glow predominantly in ultraviolet and X-ray light. The new simulation shows three orbits of a pair of supermassive black holes only 40 orbits from merging. The models reveal the light emitted at this stage of the process may be dominated by UV light with some high-energy X-rays, similar to what’s seen in any galaxy with a well-fed supermassive black hole. Three regions of light-emitting gas glow as the black holes merge, all connected by streams of hot gas: a large ring encircling the entire system, called the circumbinary disk, and two smaller ones around each black hole, called mini disks. All these objects emit predominantly UV light. When gas flows into a mini disk at a high rate, the disk’s UV light interacts with each black hole’s corona, a region of high-energy subatomic particles above and below the disk. This interaction produces X-rays. When the accretion rate is lower, UV light dims relative to the X-rays. Based on the simulation, which ran on the National Center for Supercomputing Applications’ Blue Waters supercomputer at the University of Illinois at Urbana-Champaign, the researchers expect X-rays emitted by a near-merger will be brighter and more variable than X-rays seen from single supermassive black holes. The pace of the changes links to both the orbital speed of gas located at the inner edge of the circumbinary disk as well as that of the merging black holes.
