Travel the universe with Dr. Ethan Siegel as he answers the biggest questions of all
It burns so hot and intense, it’s probably already gone. But what a sight!
“The flame that burns twice as bright burns half as long.” –Lao Tzu

160,000 light years away in the Large Magellanic Cloud lies the Tarantula Nebula (30 Doradus), the largest star-forming nebula in the local group at over 1,000 light years across. Littered with millions upon millions of newly-formed stars, the gas, dust and ionized, X-ray emitting plasma tells a universal tale of cosmic rebirth that’s common to all the stars we can see. At the center of this nebula, though, the super star cluster — R136 — contains over half-a-million stars on its own, including the most massive one in the known Universe.
Containing 72 uniquely identified O-class and Wolf-Rayet stars in the central core, the shortest-lived, hottest, bluest and brightest stars in the Universe, it includes the record-holder R136a1, at 260 times the mass and more than 7,000,000 times the luminosity, mostly in the ultraviolet, of our Sun. Shown below in visible light, a UV-visible composite, infrared and then all wavelengths combined, a large number of these stars — only about a million years old — are likely already dead, with the light (and neutrinos) from supernovae destined to reach us at any time.

Mostly Mute Monday tells the story of a single object in images, videos, and 200 words, maximum. To celebrate Hubble’s 25th anniversary, April 2015 will focus exclusively on objects imaged, spectacularly with the Hubble Space Telescope.
Obscured by our galactic plane, this once-unknown sight of the southern skies — Westerlund 2 — may house the Milky Way’s next supernova! “The wonder is, not that the field of the stars is […]
A galaxy cluster that’s been actively devouring matter for hundreds of millions of years blows all the records away. “The world exploded into billions of atoms, and when it rearranged […]
Incredible canvases, created with the burning ends of incense sticks. “Every act of creation is first an act of destruction.” –Pablo Picasso When it comes to the art we make, […]
