Watch: Our Living Planet From Space

Life makes Earth unique among the thousands of other planets we’ve discovered so far – there may be extraterrestrial life, or maybe notNotes 1, but it is the only “living planet” that we know of. Since 1997Notes 2, NASA satellites have continuously observed all plant life at the surface of the land and ocean. This view of life from space is furthering knowledge of our home planet, and how it’s changing.

In the Northern Hemisphere, ecosystems wake in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves – and a fleet of Earth-observing satellites track the spread of vegetation. Meanwhile, in the oceans, microscopic plants drift through sunlit surface waters blooming into billions of carbon-dioxide-absorbing, oxygen-producing organisms – and satellites map the swirls of their color.

Living on Mars is a terrible idea, scientist say. We should colonize Titan, instead

In September 2017, Elon Musk, the founder and CEO of SpaceX has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. They are ambitiously planning to send the first humans to Mars as early as 2024 to build the foundations for the first Martian city. But is Mars really the best place for humans to settle? Some scientists, like Amanda HendrixNotes 1, the American planetary scientist, thinks it’s not, and we should be looking somewhere else and colonize Titan, Saturn’s largest moon, instead.

Watch: Test Flight #1 of NASA’s Mars 2020 Supersonic Parachute

On October 4, 2017, NASA has tested Mars 2020’s supersonic parachute, which will slow down the spacecraft down as it enters the Martian atmosphere at over 12,000 mph (around 19500 km/h, or 5.4 kilometers per second). Mars 2020 is a Mars rover mission by NASA’s Mars Exploration Program. The planned launch will be, as the mission’s name suggests, in 2020. The mission will seek signs of ancient Martian life by investigating evidence in place and by caching drilled samples of Martian rocks for potential future return to Earth.

The coldest place in the Universe exists on Earth

It may sounds strange, but the coldest place in the Universe is not anywhere in the vast, cold outer space – it exists here on Earth. Well, it is not actually a natural place you can come across. It is in a laboratory in M.I.T. (Massachusetts Institute of Technology).

Top 10 Most Iconic Photos of Earth from Space

Earth is actually a fragile and isolated rock, a “blue marble” in a vast, cold and hostile space. But only after seeing our planet from space we truly understood that. Seeing the Earth first time from a distance was a powerful experience which has changed the way we see our planet. Here are the top 10 most iconic photos of Earth from space.

The moment the spacewalking record was broken

On February 7, 1984, during the STS-41-B (the tenth NASA Space Shuttle mission and the fourth flight of the Space Shuttle Challenger), NASA astronaut Bruce McCandless II (b. 1937) made the first ever untethered free flight using the Manned Maneuvering UnitNotes 1. With a distance of 98 meters (320 feet) from the space shuttle, he also broke the spacewalking record.

Point Nemo – The Spacecraft Graveyard

In the middle of the South Pacific Ocean, there’s a location called “Point Nemo”. It’s not a place that humans live – in fact there is no land there – not an island, not even a small rock. It is actually the remotest place from any human civilization you can find on Earth. It lies at least 2,688 km (1,670 mi) from the nearest land. It is also called as “Oceanic pole of inaccessibility”.Notes 1

LIGO detects gravitational waves from neutron star merger

Carl Sagan’s famous quote says “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.” In that famous quote, Sagan makes reference to the whole universe started off with hydrogen and helium, all stars produce helium, and then stars over a certain mass threshold produce carbon, nitrogen, oxygen and lots of heavier elements – which are also the source of the life. The star stuff is inside us – every living thing on Earth.

But, even stars are aren’t powerful enough to create heavy elements like silver, gold, and cesium. Since the 1950s, scientists have wondered: where do most of the elements in the periodic table come from?

Watch the First-Ever 360-Degree Spacewalk Video

Russian TV network Russia Today (RT) has released the first 360-Degree Spacewalk Video ever. The video is recorded by the Russian Cosmonauts Sergey Ryazansky and Fedor Yurchikhin outside the International Space Station (ISS) while doing their 7.5-hour spacewalk on August 16, 2017. The video contains breathtaking images of Earth.

Space Race 2.0? Lockheed Martin and NASA have teamed up to send humans to Mars

While Elon Musk and SpaceX planning to send Humans to Mars as early as 2024, the American global aerospace, defense, security and advanced technologies company Lockheed Martin has also revealed animations of a reusable rocket to colonize the red planet. The American company has teamed up with NASA, to build a space station (Mars base camp) orbiting Mars and a reusable, water-powered lander. The goal is sending humans to Mars only in a decade. The space race 2.0 is on the way!
