Top NASA tech that solved Mars myths and mysteries like never before
Elephant’s Trunk Nebula
1/10 Humans have been studying Mars for hundred of years. In 1609, Galileo was the first person to peer through a telescope and get a more intimate image of what many could only have dreamed of. (Pixabay)

2/10 An up close and personal view of the red planet emerged as time progressed and so did the capabilities of telescopes. In fact, from the late 1800s to the mid 1900s, many astronomers believed that Mars was home to majestic seas and lush areas of vegetation. The Dark markings on Mars surface were once believed to be caused by vegetation growing and dying. (Pixabay)

3/10 Some even believed that intelligent life existed on Mars just because of what they saw through their simple telescopes. But that is exactly was science is about-you make educated guesses based on what you know, then change your ideas based on what you learn. (NASA)

4/10 Now, thanks to new sophisticated equipment and robotic visits to Mars, it turns out they were caused by Martian wind. It was not until the 1960s, when NASA's Mariner missions flew by and snapped pictures of Mars that many of the myths about the red planet were dispelled. (NASA)

5/10 That does not make Mars any less interesting. The possibility that life actually existed once on Mars is still a distinct possibility. Or it may even be existing on Mars today! No, not in the form of little green men, but on a microbial level. (NASA)

6/10 Now, taking pictures is great and all. But nothing is better than getting to know the real thing. So, to get a better feel of Mars, Scientists and engineers built some nifty technologies, from spacecrafts to reach Mars and rovers (vehicles) to actually trundle and explore the planet. (NASA/JPL)

7/10 Among the earliest tech deployed for Mars was Phoenix. It was launched on August 4, 2007 and so began its 9-month long, 681 Million km journey to the legendary red planet. Now, landing on a planet is not as easy as simply dropping a spacecraft onto it. There is actually a lot of steps to the process. (NASA)

8/10 On May 25, 2008, Phoenix entered Mars atmosphere. It used its heat shield to slow down the high speed entry of 5600 meters per second or around 12500 miles per hour. It released a supersonic PARACHUTE, then detached from its parachute and used its rocket engines to land safely on the planet's surface. Phoenix' landing spot was further north and closer to the ice covered poles than any spacecraft has ever been before. (NASA)

9/10 Phoenix had two primary goals: One was to study the history of water in the Martian arctic and the other was to search for evidence of a habitual zone and assess the biological potential of the ice soil boundary. And to do that the spacecraft was packed full of gizmos and gadgets to perform all sets of experiments and tests. One of these gizmos was a robotic arm with a shovel attached. It was used to dig up samples of the martian soil for experiments! (NASA)

10/10 Another top tech on the Mars surface was the Surface Stereo Imager, which is really just a fancy name for the camera. Three surface stereo imagers were Phoenix' eye. Engineers built the device with two optical lenses that would allow for a three dimensional view, just like our eyes. And the SSI sent back some amazing images of the martian landscape.

Elephant’s Trunk Nebula

The makeup of a Nebula consists of gases, mainly hydrogen and helium. Although these gases are spread out, they can be pulled together by gravity. As they clump together, their gravity increases by such an amount that the gas cloud collapses, causing the material at the center of the core to heat up, and this is the birth of a star, according to NASA. This is why a Nebula is also called a Star Nursery.

NASA releases its Astronomy picture of the day on a daily basis. December 12's image is a mesmerizing snapshot of the Elephant's Trunk Nebula. The image was captured by astronomer Bernard Miller, an Arizona based retired electronic design engineer. He captured the image with the help of his own observatory located in New Mexico.

The Elephant's Trunk Nebula is one of the star-forming regions located in the IC 1396, the winding Elephant's Trunk nebula lies just below center.

NASA posted an explanation with the image, “Is there a monster in IC 1396? Known to some as the Elephant's Trunk Nebula, parts of gas and dust clouds of this star formation region may appear to take on foreboding forms, some nearly human. The only real monster here, however, is a bright young star too far from Earth to hurt us. Energetic light from this star is eating away the dust of the dark cometary globule near the top of the featured image. Jets and winds of particles emitted from this star are also pushing away ambient gas and dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a much larger region on the sky than shown here, with an apparent width of more than 10 full moons.”

More about Nebulas

Nebulas exist in the space between stars, known as the Interstellar space. In fact, there is a Nebula close to Earth which could possibly be the remnant of the dying star, according to NASA. It is called the Helix Nebula and is located approximately 700 light-years away from Earth.

NASA captures the Nebulas with the help of its Spitzer Space Telescope, Hubble Space Telescope and the new James Webb Space Telescope.
