10 Amazing Space Discoveries by the World’s Largest Flying Observatory

On the night of May 26, 2010, the Stratospheric Observatory for Infrared Astronomy, or SOFIA, the world’s largest flying observatory, first peered into the cosmos. Its mission: to study celestial objects and astronomical phenomena with infrared light. Many objects in space emit almost all their energy at infrared wavelengths. Often, they are invisible when observed in ordinary, visible light. Over the last decade, the aircraft’s 106-inch telescope has been used to study black holes, planets, galaxies, star-forming nebulas and more! The observations have led to major breakthroughs in astronomy, revolutionizing our understanding of the solar system and beyond. To celebrate its 10 years of exploration, here’s a look at the top 10 discoveries made by our telescope on a plane:

The Universe’s First Type of Molecule

Scientists believe that around 100,000 years after the big bang, helium and hydrogen combined to make a molecule called helium hydride. Its recent discovery confirms a key part of our basic understanding of the early universe.

A New View of the Milky Way

More than a pretty picture, this panorama of cosmic scale reveals details that can help explain how massive stars are born and what’s feeding our Milky Way galaxy’s supermassive black hole.

When Planets Collide

A double-star system that is more than 300 light-years away likely had an extreme collision between two of its rocky planets. A similar event in our own solar system may have formed our Moon.

How A Black Hole Feasts

Fear not, the dark, my friend. And let the feast begin! Magnetic fields in the Cygnus A galaxy are trapping material where it is close enough to be devoured by a hungry black hole.

Somewhere Like Home

The planetary system around Epsilon Eridani, a star located about 10 light-years away, has an architecture remarkably similar to our solar system. What’s more, its central star is a younger, fainter version of our Sun.

A Quiet Place

Black holes in many galaxies are actively consuming material, but our Milky Way galaxy’s central black hole is relatively quiet. Observations show magnetic fields may be directing material around, not into, the belly of the beast.

The Great Escape

Ever wonder how material leaves a galaxy? The wind flowing from the center of the Cigar Galaxy is so strong it’s pulling a magnetic field — and the mass of 50 to 60 million Suns — with it.

Exploding Star, New Worlds

What happens when a star goes boom? It turns out that supernova explosions can produce a substantial amount of material from which planets like Earth can form.

Stellar Sibling Rivalry

They say siblings need time and space to grow, but here’s one that really needs some room. A newborn star in the Orion Nebula is clearing a bubble of space around it, preventing any new luminous family members from forming nearby.

Clues to Life’s Building Blocks

Radiation from stars is making organic molecules in nebula NGC 7023, also known as the Iris Nebula, larger and more complex. The growth of these molecules is one of the steps that could lead to the emergence of life under the right circumstances.

SOFIA is a modified Boeing 747SP aircraft that allows astronomers to study the solar system and beyond in ways that are not possible with ground-based telescopes. Find out more about the mission at www.nasa.gov/SOFIA.

Hey, I’m sorry if you’ve already answered this question, but in among the Thane/land nonsense, you mentioned silver arm bands. What is the significance of that?

A jarl or thane was bound to be generous and was expected to give out gifts of great worth to those who they led. Silver was the favored metal of the Norse, though gold was appriciated as well. The Norse used a bullion based system of exchange, and a bracelet or other jewelry is easily traded, and of course functions as an obvious display of your wealth. The Norse loved the shit out of decorating themselves, and particularly with silver jewelry, and particularly particularly with bracelets or arm bands.

So a leader is expected to give out treasures won by raiding (a leader who hoards their wealth is looked upon unfavorably) and one of the most popular forms of that wealth is in the form of arm bands.

The arm rings were also similar to the rings upon ring-hilted swords, which oaths were sworn upon, and the ring is a symbol of Thor. Because of this, and because of their association with being given by your lord, arm rings were often conflated with the oaths of loyalty and mutual burdens of service expected between a lord and their war band.
