Gamma-ray bursts (GRB) are among the most peculiar phenomena in the Universe. Their sources are not very well known, although some evidence exists of possible origins. Since they were first discovered, some 50 years ago, they have sparked excitement in the scientific community, and have made astronomers believe that studying them may result in a deeper knowledge of the Universe. But, as modern-day technology makes it easier to observe them, GRB seem to present more problems than they answer, Technology Review reports.
These emissions are made up of highly energetic photons, the same elementary particles that make up visible light, as well as infrared and ultraviolet radiation. The bursts contain so much light, that some experts believe known astrophysical phenomena cannot explain them, with the bursts being collimated in some way. Within a matter of seconds, these events release about as much energy as the rest of the mass of our Sun. It is now believed that GRB may have played… (Read the rest of this article at the following article source link for the full story)

Museums around the world are currently starting to introduce a new type of exhibits in their collections, and namely the 3D models of existing works. Each valuable artifact is scanned using advanced technology, and is then faithfully replicated in a three-dimensional, digital environment. This is done so that, in case anything happens, at least some of the data on the artifact remains, and also in order to facilitate looking for certain pieces, which may resemble others. The public can also benefit from the beautiful models that result from the archiving work, AlphaGalileo reports.
