It has been a long curiosity as to what Mars actually looks like. Images of the planet from afar have been shared to the public multiple times, but nobody really knows what the surface of the Red Planet really looks like until now.
NASA has successfully landed a probe on the surface of Mars. After a nearly seven-month journey and gripping landing sequence, NASA’s InSight lander has already returned its first image of the Martian surface.
Nasa’s InSight probe came to a gentle landing on the Red Planet broad, dusty plain of Elysium Planitia at 2:53 pm EST on Monday night, the first spacecraft to do so for six years. It ended an anxious wait in which the robot radioed home a series of updates on its descent.
The seven-minute rapid deceleration through the thin Martian atmosphere involved the use of small rockets, parachutes, heat shields, and shock-absorbing legs. The lander is powered by two solar panels which unfold on landing. These are capable of generating around 700 watts of power.
Engineers manning consoles at NASA’s Jet Propulsion Laboratory in California erupted in cheers, hugs, and high-fives at the confirmation that the mission was poised to start the first study of the Red Planet’s interior, from crust to core.
Applause broke out again minutes later when the lander returned its first picture. The image shown on the NASA stream demonstrates dust speckling InSight’s camera, and it shows what appears to be the Martian horizon.
The first picture showed a smudged, fisheye view of the robot’s surroundings. The image was taken through the translucent lens cap of a camera positioned on the underside of the lander.
NASA’s InSight is designed to learn about both Mars and the formation of the solar system itself. The lander will undertake a lot of different pieces of science over the coming months.

China Creates Artificial Sun That Is Hotter Than The Real One
China has built an “artificial sun” that reaches temperature six times that of the core of our closest star. The state-of-the-art reactor is designed to replicate the processes of the sun as part of a project to turn hydrogen into cost-effective green energy.
China’s “artificial sun” has reached a temperature of 180 million ºF (100 million C) with a heating power of 10 megawatts, according to scientists at the Chinese Academy of Sciences’ Institute of Plasma Physics, where the experiment was conducted. The device called the Experimental Advanced Superconducting Tokamak (EAST) is built to harness the energy of nuclear fusion, the same process that powers stars.
No, Not All of Earth’s Water Came From Asteroids, According To New Research
The belief that water came from asteroids is a “blind spot,” according to these experts.
Contrary to what most scientists would tell you, it looks like not all of our planet's water came from asteroid matetials after all. One recent research in the United States is now challenging that, claiming our science books may have not been entirely accurate all along.
It has always been believed that Earth's water came from asteroids since it was discovered that ocean and asteroidal samples contain similar ratio of deuterium to normal hydrogen. We've mostly been taught this "fact" in school but those science textbooks may have to be rewritten soon enough.
Neanderthals Possibly Went Extinct Because Of Human Interbreeding
This might explain why modern humans still have Neanderthal genes.
Researchers have several different theories on why ancients became extinct. Although some believe that Neanderthals were killed off by humans, a new report suggests it was more complicated than that. It appears that Homo neanderthalensis may have mated with our ancestors, which led to their eventual demise.
According to a new research by German scientists, Neanderthals interbred with early humans on a regular basis. This is evident in the genetic analysis of three different fossilized remains. The remains belonged to a Neanderthal, an early human as well as a modern human. Interestingly, it revealed that interbreeding may have been the true cause of the extinction of Homo neanderthalensis.
Neanderthals possibly mated themselves into extinction.
