The upper atmosphere of the Sun is dominated by plasma filled magnetic loops (coronal loops) whose temperature and pressure vary over a wide range. The appearance of coronal loops follows the emergence of magnetic flux, which is generated by dynamo processes inside the Sun. Emerging flux regions (EFRs) appear when magnetic flux bundles emerge from the solar interior through the photosphere and into the upper atmosphere (chromosphere and the corona). The characteristic feature of EFR is the Ω-shaped loops (created by the magnetic buoyancy/Parker instability), they appear as developing bipolar sunspots in magnetograms, and as arch filament systems in Hα. EFRs interact with pre-existing magnetic fields in the corona and produce small flares (plasma heating) and collimated plasma jets. The GIFs above show multiple energetic jets in three different wavelengths. The light has been colorized in red, green and blue, corresponding to three coronal temperature regimes ranging from ~0.8Mk to 2MK.

I’m on day 321 of my #YearInSpace, and today I surpassed 500 days in space total. Let’s chat! Sat., Feb. 13 at 1:45 p.m. ET.
Kryptos is an encrypted sculpture by the American artist, Jim Sanborn, that is located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the encrypted messages it bears. Of the four messages, three have been solved, with the fourth remaining one of the most famous unsolved codes in the world. The sculpture continues to provide a diversion for cryptanalysts, both amateur and professional, who are attempting to decipher the final section. The sculptor has given clues on several occasions.

Today’s science and technology are nearing a point where computers can recreate human-level intelligence. While it is difficult to say when exactly this will happen, some researchers are suggesting that this could take place sometime this century. In the press release, Stuart Russell, a world-leading AI researcher at the University of California, Berkeley, suggests that such a development would be “the biggest event in human history.”
Professor Stephen Hawking agrees, and adds that it remains to be seen whether or not artificial intelligence will be our greatest benefit or greatest downfall. He states, “when it eventually does occur, it’s likely to be either the best or worst thing ever to happen to humanity, so there’s huge value in getting it right.”
In anticipation of this, the University of Cambridge is to establish a new interdisciplinary research centre, the Leverhulme Centre for the Future of Intelligence, which will bring together computer scientists, philosophers, social scientists, and others to examine the technical, practical, and philosophical questions that artificial intelligence raises (or will raise) for humanity in the coming century.
It will be funded by a £10 million grant from the Leverhulme Trust.

HOW DID I NOT KNOW THIS?!
The 7th Row of the Periodic Table is Finally Complete
And with a single announcement, millions of text books around the world have been made incomplete—out of date. This comes as four new elements are added to the periodic table, finally completing the table’s seventh row. The elements, 113, 115, 117, and 118 were discovered by scientists working in Japan, Russia, and America. Now, the International Union of Pure and Applied Chemistry (IUPAC, the body that is charged with overseeing standards in the world of chemistry) has confirmed the finds. Ultimately, these are the first elements to be added to the table since 2011. They were verified in an announcement released on Dec. 30.

So there’s this physics journal that uses math and science to discuss the realities of fictional universes in a super legit, peer-reviewed manner?
And they did a thing on Frozen?
Combining research on the film?
With info on how water works and stuff?
Then applied math and chemistry (and other things in which I am not especially well versed) to reach this conclusion:
So.
I never take selfies let alone smiling selfies and I’m hardly ever happy. Lemme see if this actually works
