Corrupted Echoes From the Big Bang?
Are Galaxy Clusters Corrupting the Echoes from the Big Bang?
In recent years, astronomers have obtained detailed measurements of the cosmic microwave background radiation – the ‘echo’ from the birth of the Universe during the Big Bang.
These results appear to indicate with remarkable precision that our Universe is dominated by mysterious ‘cold dark matter’ and ‘dark energy’. But now a group of UK astronomers has found evidence that the primordial microwave echoes may have be
Oxygen and carbon discovered in exoplanet atmosphere ’blow-off’
The well-known extrasolar planet HD 209458b, provisionally nicknamed ’Osiris’, has surprised astronomers again. Oxygen and carbon have been found in its atmosphere, evaporating at such an immense rate that the existence of a new class of extrasolar planets – ‘the chthonian planets’ or ‘dead’ cores of completely evaporated gas giants – has been proposed.
Oxygen and carbon have been detected in the atmosphere of a planet beyond our Solar System for the first time. Scientists using th
Counting atoms that aren’t there, in stars that no longer exist
Argonne researchers use specialized instrument
Researchers at the U.S. Department of Energy’s Argonne National Laboratory have reached for the stars – and seen what’s inside.
Argonne scientists, in collaboration with colleagues at the University of Chicago, Washington University and the Universita di Torino in Italy, examined stardust from a meteorite and found remnants of now-extinct technetium atoms made in stars long ago.
The stardust grains are tiny bit
NIST/University of Colorado Scientists create new form of matter: A fermionic condensate
Scientists at JILA, a joint laboratory of the Department of Commerce’s National Institute of Standards and Technology (NIST) and the University of Colorado at Boulder (CU-Boulder) report the first observation of a “fermionic condensate” formed from pairs of atoms in a gas, a long-sought, novel form of matter. Physicists hope that further research with such condensates eventually will help unlock the mysteries of high-temperature superconductivity, a phenomenon with the potential to improve energy ef
A new window for the study of exotic atomic nuclei.
On Friday the 30th, during the XLII international winter meeting on nuclear physics at Bormio, the first results will be announced of Finuda experiment (Nuclear Physics at Daphne), settled in Frascati at Infn National Laboratories.
Planned and made operating by a group of about forty physicists from Universities and Infn Sites of Bari, Brescia, Frascati, Pavia, Torino and Trieste, Finuda is devoted to the study of hypernuclei: nuclei composed by three different kinds of particles rather the
X-ray shout echoing through space
ESA’s X-ray observatory, XMM-Newton, has imaged a spectacular set of rings which appear to expand, with a speed a thousand times faster than that of light, around the point in the sky where a powerful gamma-ray explosion took place in early December. This is the first time that such a fascinating event, called an `echo’, has been seen in X-ray wavelengths.
This echo forms when the powerful radiation of a gamma-ray burst, coming from far away, crosses a slab of dust in our Galaxy and is sca
