NASA's internal procedure for tracking potentially dangerous asteroids that could hit Earth and for countermeasures designed to deflect the space objects is deeply flawed and heavily criticized because it exaggerates the cost and difficulty of the program.The agency had one year to prepare plans for a survey th...
Investing in space technology now may be similar to buying Microsoft shares two decades ago: highly profitable. It seems the next industry area to experience an economic boom will be the exploration of space and space tourism.Last month, the first ESA Investment Forum took place at the European Space Research and Te...
It seems physicists around the world are predicting a grim future for our heirs who will want to learn more about space. Presuming that the human race will not survive for a few hundred or thousands of millions of years, it will be impossible for other beings to observe the Universe the way we do it now, from our ga...
A gigantic telescope is about to be built in Antarctica and scientists hope to be able to catch a glimpse of neutrinos, the exotic particles traveling almost at the speed of light for millions of miles through space, passing right through planets.The name of the telescope is "IceCube" because it consists of thousand...
Black holes are space objects which have an immense gravitational field that cuts off a region of space from the rest of the universe, trapping all matter and radiation that enters that region. Black holes are thought to form in two ways, as a direct result of the gravitational collapse of a star, or by collisions be...
In recent years, space tourism has been a refreshing alternative and even if for the moment the pioneers pay around $20 million for a trip to the International Space Station, future trips will get more affordable, as many companies are trying to get a piece of the space cake. One of them is Benson Space Company of P...
One of the most important dangers of outer space missions, invisible and highly lethal, prevents humans from reaching Mars. It's not an alien creature lurking in the darkness of space, but maybe just as bad. Radiation is one of the biggest dangers to long-distance space travelers. The sudden, unpredictable occu...
NASA tested a new reusable solid rocket motor last week at the Utah test facility. It was a full scale 2-minute test that would help the development of new engines for the next generation of space shuttles, possibly even the one that will carry the next human spacecraft to the moon.It was a static firing, the engine...
A team of astronomers discovered this year the first known triple quasar, a space oddity, since the statistical probability of the existence of such a quasar says it's an extremely rare association.Quasars are extremely bright and distant astronomical objects thought to be the active nuclei of young galaxies. M...
It might sound strange, but there are some scientists (not few) who propose building a space elevator to take people to space on a cable. That would eliminate the need for rockets, or at least today's spaceships.This would be the supreme high-rise project in the world. The concept of the space elevator is actual...
A dwarf galaxy is a small galaxy composed of up to several billion stars, a small number compared to our own Milky Way's 200-400 billion stars. These small galaxies frequently orbit around larger galaxies, such as the Milky Way, the Andromeda Galaxy and the Triangulum Galaxy.NASA's Spitzer Space Telescope ...
