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)

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)

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.

The release of NASA's James Webb Space Telescope's images have provided a great chance for astronomers around the world to observe never-seen-before parts of deep space. And not just that, even what was visible before, became even more clear and this has sprung a surprise or two for astronomers. Aong the first images taken by Webb earlier this year was one of the Southern Ring Nebula. Now, researchers are analysing this data and have found evidence of an unknown star.

The Southern Ring Nebula, which is located around 2000 light-years from Earth in the constellation Vela, was earlier assumed to contain two stars. This nebula, also known as NGC 3132 had also been observed by the Hubble Space Telescope.

James Webb showed an even more complex view of the Southern Ring Nebula. It has two instruments, the Near Infrared Camera (NIRCam) which helps to observe warmer objects such as stars, and the Mid-Infrared Instrument (MIRI) which is aimed to spot dust in deep space. It was MIRI's observation which showed the first surprise- that the white dwarf was surprisingly red. Not only that, it also revealed that the stars were of almost same size- Hubble Telescope had shown one large and one small one. The larger was the star that was still alive while the smaller companion was the dead star, generally known as white dwarf. Its unexpected red colour indicated there was something else out there too.

After this, astronomers immediately wondered where did this material come from. This only indicated the presence of another invisible star orbiting the white dwarf which resulted in the gigantic dust disk, Orsola De Marco, an astrophysicist at Macquarie University told Space.com. This suddenly transformed the binary system of stars into a 3-star system.
