Today, to celebrate 25th launch anniversary of Tracking and Data Relay Satellite 6 (TDRS-6), the American communications satellite which launched by Space Shuttle Endeavour on January 13, 1993, NASA has published two amazing photos on its twitter account. The American space agency has tweeted that “Happy 25th launch anniversary to TDRS-6, launched on this day in 1993! TDRS-6 is still operational today, well past its intended design life“.

NASA (The National Aeronautics and Space Administration) has published a video that contains highlights of important events and the space agency’s achievements over the year 2017. In the video description, NASA has stated that “2017: A year of groundbreaking discoveries and record-setting exploration at NASA. The Moon became a focal point for the agency, we brought you unique coverage of the first coast-to-coast total solar eclipse in the U.S. in 99 years, we announced the most Earth-size planets ever found in the habitable zone of a star outside our solar system, and more!”

The billionaire founder of SpaceX, Elon Musk has revealed a new plan to colonize Moon and Mars with giant reusable spaceships. He provided an update on their Mars colonization plan at the International Astronautical Congress (IAC)Notes 1 in Adelaide, Australia this week. Musk plans sending 1 million people to Mars using BFRNotes 2, and “making life multiplanetary”. He has highly ambitious plans like launching and landing at least two uncrewed cargo ships on Mars as early as 2022.

On February 22, 2017, NASA astronomers has announced that seven Earth-sized planets have been discovered around an ultra-cool dwarf star named TRAPPIST-1 which is located around 39 light-years from the Earth. And what’s more – three of them are orbiting their star in the habitable zone. Then, an international team of astronomers led by the Swiss astronomer Vincent Bourrier from the Observatoire de l’Université de Genève used the NASA/ESA Hubble Space Telescope to estimate whether there might be water on the planets of TRAPPIST-1 system. Now, on August 31 2017, the team announced that their findings suggest that “the outer planets of the system might still harbor substantial amounts of water”, including the three planets within the habitable zone of the star – TRAPPIST-1e, f and g. This result lends further weight to the possibility that these planets may indeed be habitable.

In 1950, the Italian physicist Enrico Fermi was chatting with his colleagues at the Los Alamos National Laboratory(1). They talked about recent rise in UFO reports, then the conversation shifted to other subjects. But during the lunch, Fermi suddenly asked “Where is everybody?”. He was talking about the extraterrestrial life, especially intelligent life. He made some calculations on the probability of Earth like planets, the beginning of life, the probability of intelligent life and high technology and concluded that we ought to have been visited long ago and many times over.
But, there is no reliable evidence aliens have visited Earth and we have observed no intelligent extraterrestrial life with current technology nor has SETI found any transmissions from other civilizations. The Universe, apart from the Earth, seems “dead”.
So, where is everybody?

In fact, we’re all living in a fast-moving spacecraft named Earth. Our planet is moving around our sun in an elliptical (an ellipse which is very close to a circle) orbit. The Sun is (our solar system, the Sun, Earth and all the other planets and objects) whirls around the center of our galaxy. And, our galaxy and the other galaxies in our neighborhood are also rushing towards a structure called the Great Attractor, a region of space roughly 150 million light-years (one light year is about six trillion miles) away from us. This Great Attractor, having a mass 100 quadrillion times greater than our sun and span of 500 million light-years, is made of both the visible matter that we can see along with the so-called dark matter that we cannot see.
