More than 500,000 pieces of debris, or “space junk,” are tracked as they orbit the Earth. They all travel at speeds up to 17,500 mph, fast enough for a relatively small piece of orbital debris to damage a satellite or a spacecraft.
The acronym “NASA” stands for National Aeronautics and Space Administration. Before NASA was formed, the National Advisory Committee for Aeronautics (NACA) was started by President Woodrow Wilson to supervise and direct the scientific study of the problems of flight. From then to present day, much has happened. So, here are some interesting facts about NASA.
Oldest Star System in Galaxy Discovered by NASA ‘could Point to Extremely Advanced Alien Civilisations’January 27, 2015 | Editors
Astronomers have found a star system that bears striking resemblance to our inner solar system.
Children and adults alike marvel at the rings around Saturn. In a model of our solar system, Saturn — and its rings —is typically the one that gets the most attention. But while it is easy to be fascinated by Saturn, astronomers have recently found an exoplanet with an even grander expanse of wings that is sure to wow a new generation of stargazers.
It’s hard to imagine what life would look like if we were rotating around some star other than the sun. So the Russian Federal Space Agency imagined for us. And it looks awesome. The video above puts different stars at the center of our solar system, envisioning Earth in a very different light. Five different lights, actually.
The amount of data and stunning imagery being delivered by NASA’s Curiosity rover has given us new insight into Mars, but a new concept vehicle for future missions could dramatically increase our knowledge of the red planet. NASA is gearing up to create a robotic helicopter that can serve as a scout for more traditional, land-based rovers.
If a black hole is Voldemort, a quasar is Sauron; Despite being concentrated in an area no larger than our solar system, one, single quasar can outshine our galaxy by a factor of 100, generating more energy in moments than the Sun ever will. However, the mechanism by which they are powered is remarkably simple: at the heart of every quasar is a black hole that has been turbocharged. At least, that’s the working theory anyway.
A new space telescope concept, named the Aragoscope after French scientist Francois Arago who first detected diffracted light waves around a disk, could allow scientists to image space objects like black hole “event horizons” and plasma swaps between stars, said Cash of CU-Boulder’s Center for Astrophysics and Space Astronomy.
If you believe the movies, messages from outer space tend to be carried by UFOs or cute little aliens. But it turns out that secret dispatches from the stars are actually concealed in much less exciting envelopes. Scientists have long suspected that ancient messages lurk within meteorites which crash to earth. Now they have finally proved this theory.
The galaxy is many things. It is very large. It is very confusing. But, what if our galaxy was just one massive wormhole that we could use to travel from one end of the cosmos to another? That might sound like something from Christopher Nolan’s 2014 film, Interstellar, but physicists now think it’s also something that’s very possible.
We Earthlings love to dream, conjure and extrapolate. If you pose a question such as, “What if Earth had Saturn’s rings?” with all the resources available these days someone will not only answer the question but create some beautiful graphics to depict it!
