Instagram puede estar dominado por celebrities e influencers, pero hay fotos intelectualmente más curiosas que siguen siendo increíbles.
La cuenta de Instagram de la NASA es una se las más populares con más de 7.7 millones de seguidores, y este año le dedicamos esta nota debido a las fascinantes fotos que postearon.
10.- Las Perseidas, una lluvia de meteoros.
The Perseid meteor shower is caused by debris from Comet Swift-Tuttle as it swings through the inner solar system and ejects a trail of dust and gravel along its orbit. When the Earth passes through the debris, specs of comet-stuff hit the atmosphere at 140,000 mph and disintegrate in flashes of light. Meteors from this comet are called Perseids because they seem to fly out of the constellation Perseus. Last year, this meteor shower peaked during a bright “supermoon”, so visibility was reduced. Luckily, this year, the show was especially awesome because the Moon is nearly new when the shower peaked on Aug. 12-13, 2015. In this 30 second exposure, a meteor streaks across the sky during the annual Perseid meteor shower Aug. 13, 2015, in Spruce Knob, West Virginia.

9.-Perspectiva vertical de la Tierra.
With the ability to now send vertical images, we want to show you the world. Here’s a look at the Earth from the International Space Station (@ISS) shared by European Astronaut Samantha Cristoforetti. When she shared this view from orbit 250 miles up, she wished everyone “Good night from space” in English & Italian on May 14, 2015.

8.- Italia de noche.
Before drifting off to sleep, NASA astronaut Scott Kelly (@stationcdrkelly) captured this images from the International Space Station and wrote, ” Day 180. Moonlight over Italy. #BuonaNotte Good night from @ISS! #YearInSpace.” Kelly is living and working off the Earth, for the Earth aboard the station for a yearlong mission. Traveling the world about 250 miles above the Earth, and at 17,500 mph, he circumnavigates the globe more than a dozen times a day. Image Credit: NASA #nasa #spacestation #space #earth #iss
7.- “Calabaza” solar para Halloween.
Happy Halloween! We present a solar ‘pumpkin!’ Active regions on the sun combined to look something like a jack-o-lantern’s face on October 2014. The image was captured by NASA’s Solar Dynamics Observatory, or SDO, which watches the sun at all times from its orbit in space. The active regions in this image appear brighter because those are areas that emit more light and energy.

6.- África desde el espacio.
NASA astronaut Scott Kelly (@StationCDRKelly) captures photographs and video of the Earth from the International Space Station (@ISS) routinely. On Nov. 17, 2015, Kelly shared this stunning image, writing “Unmistakably #Africa.” Image Credit: NASA #nasa #space #iss #spacestation #yearinspace #earth
5.- Líquido de colores en el Espacio.
Colorful Liquid in Space (Part 1): Astronauts (@StationCDRKelly) on the International Space Station (@ISS) dissolved an effervescent tablet in a floating ball of water, and captured images using a camera capable of recording four times the resolution of normal high-definition cameras. The higher resolution images and higher frame rate videos can reveal more information when used on science investigations, giving researchers a valuable new tool aboard the space station. This footage is one of the first of its kind. The cameras are being evaluated for capturing science data and vehicle operations by our engineers.

4.-Arqueología cósmica desde la Vía Lactea.
Conducting a “cosmic archaeological dig” at the very heart of our Milky Way galaxy, astronomers uncovered the blueprints of our galaxy’s early construction phase. Peering deep into the Milky Way’s crowded central hub of stars, researchers using our Hubble Space Telescope have uncovered for the first time a population of ancient white dwarfs — smoldering remnants of once-vibrant stars that inhabited the core. Finding these relics at last can yield clues to how our galaxy was built, long before Earth and our sun formed. This image is a small section of Hubble’s view of the dense collection of stars crammed together in the galactic bulge. The region surveyed is located 26,000 light-years away.

3.- Luces del Norte.
On the night of Oct. 8, a photographer in Harstad, Norway captured this image of the dancing northern lights. Auroras are created when fast-moving, magnetic solar material strikes Earth’s magnetic bubble, the magnetosphere. This collision rattles the magnetosphere in an event called a geomagnetic storm, sending trapped charged particles zooming down magnetic field lines towards the atmosphere, where they collide brilliantly with molecules in the air, creating auroras. Though many geomagnetic storms are associated with clouds of solar material that explode from the sun in an event called a coronal mass ejection, or CME, this storm was caused by an especially fast stream of solar wind. “Geomagnetic storms caused by high-speed solar wind streams aren’t uncommon,” said Leila Mays, a space physicist at our Goddard Space Flight Center in Greenbelt, Maryland. “Near solar minimum-when solar activity like CMEs are less frequent-these fast streams are actually the most common cause of geomagnetic storms that create auroras.” Image courtesy of Johnny Henriksen/Spaceweather.com #nasa #space #photography #aurora #spaceweather #nasabeyond #sun #earth #science Una foto publicada por NASA (@nasa) el
2.- Fenómeno de la Luna Sangrienta sobre el monumento de Washington.
It’s a #SuperBloodMoon! A perigee full moon, or supermoon, is seen behind the Washington Monument during a total lunar eclipse on Sunday, Sept. 27, in Washington, DC. The combination of a supermoon and total lunar eclipse last occurred in 1982 and will not happen again until 2033.

Gorgeous Pluto! The dwarf planet has sent a love note back to Earth via our New Horizons spacecraft, which has traveled more than 9 years and 3+ billion miles. This is the last and most detailed image of Pluto sent to Earth before the moment of closest approach, which was at 7:49 a.m. EDT Tuesday – about 7,750 miles above the surface — roughly the same distance from New York to Mumbai, India – making it the first-ever space mission to explore a world so far from Earth. This stunning image of the dwarf planet was captured from New Horizons at about 4 p.m. EDT on July 13, about 16 hours before the moment of closest approach. The spacecraft was 476,000 miles (766,000 kilometers) from the surface. Images from closest approach are expected to be released on Wednesday, July 15.
