Just in time for Halloween, here’s the Sun looking like a giant scary flaming jack-o-lantern
The image, captured by the Solar Dynamics Observatory, is a composite which shows the sun in a blend of two wavelengths (171 and 193 Angstroms). Extreme ultraviolet light of 171 Angstroms shows the sun’s atmosphere, or corona, “when it’s quiet,” while 193 Angstroms shows hotter regions of the corona, according to NASA.

Consciousness is at the core of our very existence. An intangible constant that underpins our experience of the world. But for centuries it has been the frustrating source of a seemingly impenetrable explanatory gap – it is largely a scientific mystery.

Is consciousness real? Could it be just an illusion manufactured in the theatre of our minds? And what use is it – why did it evolve in the first place? Professor Nicholas Humphrey explores the mystery.

Atoms as big as a mountain: Neutron stars explained

Neutron Stars are some of the most strangest things in the universe. Not quite massive enough to become black holes, they’re basically atoms as big as mountains with properties so extreme that it is mind-blowing. And if you get too close to a neutron star you are in big trouble…

This is what it looks like when you boil your GoPro just so you can see what it looks like to poach an egg in real time

This Japanese guy nearly destroyed his GoPro in the process, but for a worth cause.

Nineteenth century astronomers had it right, 20th century got it wrong and it drastically delayed the search for exoplanets

While space based telescopes such as Hubble and Kepler have become really, really damn good at finding exoplanets now that we know what we’re looking for, there was a point in the early 20th century when scientists thought our planet-rich solar system was a total fluke, and it was likely there weren’t many other planets at all in the solar system. Problem is, this overturned 19th century ideas of planetary formation that were right all along, and would have begun the search for exoplanets much earlier. Nineteenth century astronomers believed solar systems formed in gaseous nebulae, but in the 20th century, the idea became popular that our solar system was a freak, and that all the stuff from the other bodies in it was due to another star passing too close to the sun, causing the sun to eject out all kinds of junk that became the planets and moons, and that such an event was probably extremely unlikely to happen in any other cases, if at all.

The World’s Smallest Movie: A Boy And His Atom

IBM researchers used a scanning tunneling microscope to move thousands of carbon monoxide molecules (two atoms stacked on top of each other), all in pursuit of making a movie so small it can be seen only when you magnify it 100 million times.

ESO Antenna TimeLapse
The Atacama Large Millimeter/submillimeter Array (ALMA) is a revolutionary instrument in its scientific concept, its engineering design, and its organization as a global scientific endeavor.
Thanks to its high resolution and sensitivity, ALMA will open an entirely new “window” on the Universe, allowing scientists to unravel longstanding and important astronomical mysteries, in search of our Cosmic Origins.
