New observations from the infrared Herschel Space Observatory reveal that an exploding star expelled the equivalent of between 160,000 and 230,000 Earth masses of fresh dust. This enormous quantity suggests that exploding stars, called supernovae, are the answer to the long-standing puzzle of what supplied our early universe with dust.Cosmic dust is made of various elements, such as carbon, oxygen, iron and other atoms heavier than hydrogen and helium.
Scientists have known that the masses of the largest bodies in the Universe depend on the method in which this mass is measured.Measurements of the galaxy cluster are carried out in three different regions of the electromagnetic spectrum: X-ray, optical and millimeter wavelengths, which leads to different results.
Eduardo Roseau at University of Chicago, explained that the performance of any two measurement methods may be virtually identical, but the third way will be radically different.
Scientists have discovered the most brilliant object yet from the infancy of the cosmos, a super-bright galaxy, called ULAS J1120+0641, that is the most distant one found to date. It’s the brightest object discovered from the early universe, giving off 60 trillion times as much light as our sun.The distance to the quasar was then determined from observations made with the European Southern Observatory’s Very Large Telescope and the Gemini North Telescope.
Scientists at the Research Centre NASA had the opportunity to study a mysterious substance that hides from us the most distant parts of the universe.Astronomers suspect that one of the carbon-containing compounds, called polycyclic aromatic hydrocarbons (PAHs), may cause absorption of light at several wavelengths.
supermassive black holes, which is located in the centers of most galaxies of the universe, rotate much faster than ever in the history of the universe.In their study, they based from the assumption that the twin jets of matter indicate that the black hole rotates.Martinez Sansigre and Roulins conducted computer simulations of how the power of these jets depends on the speed of rotation of a supermassive black hole, and then compared the results of this simulation with the real observations of X-ray
With the help NASAs Swift satellite astronomers was observed the object which can be potentially the farthest object yet detected in space Scientists think that this gamma-ray burst was place it at around 13.14 billion light-years away.
According the theory of Bernard Carr of Queen Mary University of London and Alan Coley from Dalhousie University in Canada, part black holes can survive the Big Bang.
Scientists from the Sloan Digital Sky Survey created the largest 3-D map of the distant universe using the light of the brightest objects in the cosmos.To creat this map scientists relied on 14,000 quasars.
Tycho supernova, which is located about 13,000 light-years from Earth, formed when its parent star divided too much material from a nearby companion, forcing it to blow up in a massive thermonuclear explosion.
