Hubble Asteroid Hunter, A Citizen Science Project Finds 1,701 Asteroid Trails In Archival Images

In its 32 years of observations , the NASA/ ESA Hubble Space Telescope has built up an archive containing hundreds of thousands of targeted observations of galaxies, the cluster of galaxies, gravitational lenses and nebulae. At times, closer objects such as asteroids pass the telescope's field of view while other targets are being observed, leaving the images' trails.

The initiative was developed by the European Science and Technology Centre (ESTEC) and the European Space Astronomy Centre's Science Data Centre (ESDC), collaborating with Google and Zooniverse. Firstly, the astronomers detected more than 37,000

Human Expedition To Mars Can Be Powered By Using Solar Energy, Say US Researchers

Image
As humanity plans an expedition to the Martian surface, one would speculate that nuclear power would be the best option for faraway crewed missions. Researchers at the University of California (UC), Berkeley , have now shown that a crewed mission to Mars could be powered by solar energy. Image Credits: Pixabay The current study is unique because the researchers compared the distinct ways of generating power and evaluated the requirements of a nuclear-powered system against various photovoltaic devices and photoelectrochemical devices. Photovoltaic devices are those devices that convert sunlight directly into electricity, whereas photoelectrochemical devices convert abundant solar energy into stored electrical energy. Comparing The Power Generating Options A small nuclear fission device is location-agnostic (independent of nuclear outpost location establishment), while the efficiency of solar power devices relies on the intensity of sunlight, surface temperature and other factors that

Can we really colonize Mars?

But since, most people agree to this thought of colonizing other planets, we thought we could scientifically discuss, whether this was really possible.  First and foremost, where do we go?  Before we can decide what we would really need on this campaign for colonization, we need to first decide, where we need to go. Do, we go towards the Sun or away from it? Or do we just pick up the nearest planet to the Earth and start our preparations? We can simply look at our immedia
