An amazing image showing both the Earth and Moon. The distance between our planet and its satellite is actually much more than many would conceptualize. It is 384,400 kilometers (about 239,000 miles) on average, but as usual, our brains cannot deal with such large numbers. Only seeing that distance makes us realize how far even the closest body in the solar system to us – and gives some clues about how big is our Solar system actually. What’s more, we’ve actually been there, the humanity managed to cover that vast distance and walked on the moon!

The hottest place in the Universe exists here on Earth, like the coldest place in the Universe. Both these extreme temperatures are not natural, they are human-made. The coldest temperature was achieved in the German physicist and professor of physics Wolfgang Ketterle’s laboratory at the Massachusetts Institute of Technology (MIT). The hottest temperature, also recognized by the Guinness Book of World Records, was achieved at CERN’s Large Hadron Collider (LHC).
On 13 August 2012 scientists at CERN’s Large Hadron Collider, Geneva, Switzerland, announced that they had achieved temperatures of over 5 trillion K and perhaps as high as 5.5 trillion K (more than 9.9 trillion °F). The team had been using the ALICE experiment to smash together lead ions at 99% of the speed of light to create a quark-gluon plasma – an exotic state of matter believed to have filled the universe just after the Big Bang.

Tech Insider published a video titled “How NASA, SpaceX, and Blue Origin’s Monster Rockets Compare”. Still, the old Saturn V, which was used by NASA between 1967 and 1973 and took humans to the Moon, is the biggest and strongest rocket ever built. But new rockets are coming and that’s finally about the change. Here is the past and future monster rockets comparison:

Are we alone in the Universe? Or any other life forms exist out there? A new study, published on the Proceedings of the National Academy of Sciences of the United States of America (PNAS)Notes 1 suggests that the life emerged so early on Earth – it should be widespread. In other words, the Universe should be filled with life.
The story goes back to 1982. 35 years ago, UCLA Scholar and Pioneer in Study of the Evolution of Life, J. William Schopf collected 3.465-billion-year-old fossils from the Apex Chert in western Australia, and interpreted them as early life. When he described the fossils in the journal Science in 1993, critics had argued that they were not early lifeforms – they were just odd minerals that only looked like biological specimens.

On Friday, December 22, 2017, SpaceX’s Falcon 9 rocket delivered the fourth set of 10 Iridium NEXT satellites in a series of 75 total satellites to low-Earth orbit for Iridium, a global leader in mobile voice and data satellite communications. A Youtube user Jim Mudgett published an amazing footage of the Falcon 9 rocket launch. Enjoy!

49 years ago today, on December 24, 1968, the crew of Apollo 8, the first manned mission to the Moon and the second manned spaceflight mission in the United States Apollo space program, took this photo, later dubbed “Earthrise”. During a broadcast that night, pilot Jim Lovell said: “The vast loneliness is awe-inspiring and it makes you realize just what you have back there on Earth.”

Crocodiles (subfamily Crocodylinae) or true crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Although they are big, they suffer from a prevalence of “big fish” stories and over-exaggeration. In the Internet age, photographs of crocodiles manipulated digitally to make the animal look much larger than it is. So, how big the largest crocodiles are actually? Here are the top 10 largest crocodiles ever recorded.

Russian Federation’s space agency Roscosmos (full name: Roscosmos State Corporation for Space Activities) plans to build a luxury hotel attached to the International Space Station (ISS). The Russian state’s company planning to complete the hotel by 2021. One week (or two weeks, not clear) accommodations will cost $40 million per person. A spacewalk option, with the accompaniment of an experienced cosmonaut, will add another $20 million o that price.

December 15, 2017, was another remarkable day for humanity’s space exploration journey: SpaceX launched a reused Dragon spacecraft atop a reused Falcon 9 rocket for the first time. The purpose of that Falcon 9 launch was to deliver over 2,200 kg (more than 4,800 pounds) of supplies, which include critical science instruments to the International Space Station. The mission was successful. After putting the Dragon spacecraft into orbit about 10 minutes after liftoff, Falcon 9 returned back and landed at Zone 1, a SpaceX facility at Cape Canaveral Air Force Station in Florida.
With that Falcon 9 launch, SpaceX, the American aerospace manufacturer, and space transport services company has moved one step closer to its dream of affordable, efficient reusable space flight. To date, SpaceX didn’t launch a pre-flown spacecraft atop a pre-flown rocket. But this time, both the Falcon 9 rocket and its payload have previous spaceflight experience. This Dragon spacecraft visited the ISS back in April 2015, and the Falcon 9 first stage launched a different Dragon toward the International Space Station in June 2017. This is the company’s 13th commercial cargo mission – also the 17th launch SpaceX has conducted in 2017, and the 20th successful first stage recovery overall for the company. Now, SpaceX can use this Falcon-9 rocket in future for the third time.
