Building a Homemade Spacecraft
Courtsey: VICE
Anyone with some brains and lots of courage can build their own space rocket using everyday, off-the-shelf products. We recently flew to Denmark to meet the founders of Copenhagen Suborbitals, a non-profit open-source D.I.Y. space endeavor.

A Next Generation Space Telescope
Courtsey: Hubble Space Telescope
In the 24 years Hubble has been exploring the universe, we have gone through four U.S. Presidents, and 5 U.K. Prime Ministers. For many astronomers, this time represents almost half a career and for people under 25, they have never known a world without the Hubble Space Telescope in it.
This exciting hangout will take a look at all of the things the Hubble Space Telescope has done for us, both scientifically and culturally with Dr. Martin Barstow, Pro-Vice-Chancellor, Head of the College of Science & Engineering, Professor of Astrophysics & Space Science and President of the Royal Astronomical Society.
NASA Sends Hi-Tech 'Sandals' Into Space: BREAKING NEWS
Courstsey: Latest News UP
NASA has sent a pair of high-tech 'space sandals' to the International Space Station (ISS) to better understand how heavy loads can damage an astronaut's bones and muscles.

Reality among Largest Black Holes in the Universe
Courtsey: list25
Much like a black body in thermodynamics, a black hole is a region of space that pulls everything and prevents anything from escaping, even light. The reason it is called a "black" hole is because it sucks up all the light that hits its border and reflects nothing. Formed when an amply compact mass deforms space and time, a black hole has a defined surface known as the "event horizon" which marks the point of no return. Little is known about black holes but several scientists in history have developed their own theories about their properties and structures. Here is a list of 25 crazy facts about black holes.

The Largest Black Holes in the Universe
Courtsey: SpaceRip
Our Milky Way may harbor millions of black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?
A new era in astronomy has revealed a universe long hidden to us. High-tech instruments sent into space have been tuned to sense high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes and do not penetrate our atmosphere. On the ground, precision telescopes are equipped with technologies that allow them to cancel out the blurring effects of the atmosphere. They are peering into the far reaches of the universe, and into distant caldrons of light and energy. In some distant galaxies, astronomers are now finding evidence that space and time are being shattered by eruptions so vast they boggle the mind.
We are just beginning to understand the impact these outbursts have had on the universe: On the shapes of galaxies, the spread of elements that make up stars and planets, and ultimately the very existence of Earth. The discovery of what causes these eruptions has led to a new understanding of cosmic history. Back in 1995, the Hubble space telescope was enlisted to begin filling in the details of that history. Astronomers selected tiny regions in the sky, between the stars. For days at a time, they focused Hubble's gaze on remote regions of the universe.
These hubble Deep Field images offered incredibly clear views of the cosmos in its infancy. What drew astronomers' attention were the tiniest galaxies, covering only a few pixels on Hubble's detector. Most of them do not have the grand spiral or elliptical shapes of large galaxies we see close to us today.
Instead, they are irregular, scrappy collections of stars. The Hubble Deep Field confirmed a long-standing idea that the universe must have evolved in a series of building blocks, with small galaxies gradually merging and assembling into larger ones.

Future of Human Space Exploration
Courtsey:NASA.gov video
Now
that the Space Shuttle era is over, NASA is writing the next chapters in
human Spaceflight with its commercial and international partners. It is
advancing research and technology on the International Space Station,
opening low-Earth orbit to US industry, and pushing the frontiers of
deep space even farther ... all the way to Mars.

Take a trip to distant realms of our solar system to discover where secret forms of life may lie hidden. Combining the latest telescope images with dazzling animation, this program immerses audiences in the sights and sounds of alien worlds, while top astrobiologist explain how these places are changing how we think about the potential for life in our solar system. We used to think our neighboring planets and moons were fairly boring mostly cold, dead rocks where life could never take hold. Today, however, the solar system looks wilder than we ever imagined.
How Space Energy helps us on Earth
In space we cannot afford to lose even a Watt of energy. Space engineers
are probably the most energy-conscious scientists on Earth as they try
to preserve every single microwatt used. They have taken energy
efficiency to a new high and are sharing this knowledge for use in
applications on Earth.
Energy is one of the big challenges on Earth and space technology is one of the tools to resolve some of the issues involved. The space sector is a forerunner in developing renewable energy, for instance, the first major use of solar cells was to power satellites during their operation in space.
Satellites can also be used to monitor the Earth to find the right sites for implementing renewable energy hardware, such as solar panels, windmills, etc. Satellites have also enabled us to use navigation systems that take us from one place to the next in a much more energy-efficient way. And through teleconferences, also made possible by telecommunication satellites, there is often not even the need to travel, thereby preserving a large amount of energy.
