Astronomers have discovered a relic from the early universe - a star that may have been among the second generation of stars to form after the Big Bang.
After years of successful concealment, the most primitive stars outside our Milky Way galaxy have finally been unmasked.
Researchers of the University of Granada have conducted the most complete worldwide analysis of the chemical composition and evolutionary state of a spectral type R carbon star.
NASA's Spitzer Space Telescope has captured an action-packed picture of the nearby Small Magellanic Cloud, a small galaxy that looks like a wispy cloud when seen from Earth.
Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered two distinct kinds of "rejuvenated" stars in the globular cluster Messier 30.
A new object with an age of thousands of millions of years and a mass of one tenth of the Sun, placing it at the frontier between low-mass stars and brown dwarfs, has been discovered as the furthest of its class in Milky Way.
Recently astronomers used the Suzaku orbiting X-ray observatory, operated jointly by NASA and the Japanese space agency, to discover the largest known reservoir of rare metals in the universe.
BOSS, the Baryon Oscillation Spectroscopic Survey, is the most ambitious attempt yet to map the expansion history of the Universe using the technique known as baryon acoustic oscillation (BAO).
Data from NASA's Galaxy Evolution Explorer spacecraft may force astronomers to discard the assumption that stars of certain sizes form in certain quantities. For decades, astronomers have believed the proportion of small to big stars was fixed.
Using ESO's Very Large Telescope, astronomers have succeeded in measuring the size of giant galaxy Messier 87 and were surprised to find that its outer parts have been stripped away by still unknown effects.
