The Universe`s infant galaxies enjoyed rapid growth spurts forming stars like our sun at a rate of up to 50 stars a year, according to scientists at Durham University.
The findings show that "stellar nurseries" within the first galaxies gave birth to stars at a much more rapid rate than previously expected, the researchers from Durham`s [...]

A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by Sarah Church of the Kavli Institute for Particle Astrophysics and Cosmology, jointly located at the Department of Energy`s SLAC National Accelerator Laboratory and Stanford University, and by Walter Gear, of Cardiff University in the United [...]

Astronomers have tracked down a gigantic, previously unknown assembly of galaxies located almost seven billion light-years away from us. The discovery, made possible by combining two of the most powerful ground-based telescopes in the world, is the first observation of such a prominent galaxy structure in the distant Universe, providing further insight into the cosmic [...]

Evidence for a thin veil of carbon has been found on the neutron star in the Cassiopeia A supernova remnant. This discovery, made with NASA`s Chandra X-ray Observatory, resolves a ten-year mystery surrounding this object.
"The compact star at the center of this famous supernova remnant has been an enigma since its discovery," said Wynn Ho [...]

An unusual supernova rediscovered in seven-year-old data may be the first example of a new type of exploding star, possibly from a binary star system where helium flows from one white dwarf onto another and detonates in a thermonuclear explosion.
In a paper first published online Nov. 5 in the journal Science Express, University of California, [...]

The spectacular new camera installed on NASA`s Hubble Space Telescope during Servicing Mission 4 in May has delivered the most detailed view of star birth in the graceful, curving arms of the nearby spiral galaxy M83.
Nicknamed the Southern Pinwheel, M83 is undergoing more rapid star formation than our own Milky Way galaxy, especially in its [...]

Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang.
The finding is the first age-confirmation of a so-called dropout galaxy at that distant time [...]

Earth`s location in the Universe is utterly unremarkable, despite recent theories that propose toppling a foundation of modern cosmology, according to a team of University of British Columbia researchers.
Polish astronomer Nicolaus Copernicus`s 1543 book, On the Revolutions of the Heavenly Spheres, moved Earth from being the centre of the Universe to just another planet orbiting [...]

The CoRoT satellite*, has recently observed a star analogous to the young Sun at an age of approximately 500 million years, named CoRoTExo-2a. This star is accompanied by a giant planet orbiting around it in only 1.7 days, that was discovered by the CoRoT Extrasolar Planet Team.
An investigation on the intrinsic variations of the star [...]
