Although the composition of dark energy remains a mystery, scientists have already started taking short but decisive steps to understand dark matter. In April, Dr. Samuel Ting, the 1976 Nobel Prize in Physics, announced that the? Alpha Magnetic Spectrometer, a? The particle detector that has been operating on the International Space Station for two years has counted more than 400,000 positrons, the antimatter of electrons.

"A frenetic pace". This is how astronomers from the European Space Agency (ESA) describe the activity of a recently discovered very distant galaxy that manufactured stars at a rate 2,000 times that of the Milky Way when the Universe was less than a billion years old. The simple fact of its existence, discovered thanks to the Herschel space observatory, challenges current theories about the evolution of galaxies.

Throughout their life, stars undergo changes in their mass, pressure, composition and internal structure to, by exhausting their fuel and depending on their initial...

NASA's Spitzer infrared space telescope has obtained new images of the NGC 7000 Nebula, better known as the North American Nebula, in which thousands of young stars born at 1,800 BC can be seen.

More than a hundred scientists, some Spanish, have teamed up to detect the elusive extragalactic background light or EBL (extragalactic background light). It is the set of photons generated by all the stars and black holes in the universe, and from which the oldest stellar emissions can be deduced. The study was made with data from the Fermi gamma-ray space telescope.

The European Space Station (ESA) is going to carry out an ambitious project that consists of nothing less than surveying one billion stars within our galaxy. It is called the Gaia mission and it will take off at the end of 2013 from the European Spaceport of French Guiana.

If you don't think the Sun is shining enough on this planet, you can always move to PH1, a newly discovered exoplanet with four stars. It has been discovered by a team of amateur astronomers, in collaboration with experts from Yale University, who explain that it revolves around a binary star system that, in turn, is orbited by a second pair of distant stars, which gives rise to an "extremely rare" planetary configuration.

An astronomical study reveals that one in five supernovae that explode in nearby galaxies go unnoticed in optical studies, a rate that increases to four out of five in the case of distant galaxies. The research, published in the journal The Astrophysical Journal and in which the Spanish Miguel Ángel Pérez-Torres, from the Instituto de Astrofísica de Andalucía (IAA-CSIC) participates, agrees with the star formation rate that astronomers handle and that had been discussed in previous works.
