New observations from ESO's Very Large Telescope have, for the first time, provided direct evidence that young galaxies can grow by sucking in the cool gas around them and using it as fuel for the formation of many new stars. In the first few billion years after the Big Bang the mass of a typical galaxy increased dramatically and understanding why this happened is one of the hottest problems in modern astrophysics. The results appear in the October 14 issue of the journal Nature. The first...

A telescope in Arizona has taken the sharpest pictures yet of deep space from Earth. This new system provides a level of clarity never seen before. The technology uses adaptive optics, which is a mechanism that allows a telescope's mirror to bend in order to compensate for the blurring of light as it passes through the Earth's atmosphere. LBT scientists said the new system is installed on the $120 million Large Binocular Telescope (LBT) on Mount Graham in Arizona.  The system is...

The next generation of adaptive optics has arrived at the Large Binocular Telescope in Arizona, providing astronomers with a new level of image sharpness never before seen. Developed in a collaboration between Italy's Arcetri Observatory of the Istituto Nazionale di Astrofisica, or INAF, and the University of Arizona's Steward Observatory, this technology represents a remarkable step forward for astronomy. "This is an incredibly exciting time as this new adaptive optics system allows us to...

An Italian team of astronomers, scientists and historians says it has built a telescope using 17th-century astronomer Galileo Galilei's original design. The team spent two years getting the telescope ready for the International Year of Astronomy, which marks the 400th anniversary of Galileo's discoveries, including the then-heretical conclusion that the Earth revolved around the sun, not vice versa. The team from Florence's Museum of the History of Science and the national institutes of...

AMBER instrument on VLTI Probes Environment of Stars Using the newly installed AMBER instrument on ESO's Very Large Telescope Interferometer, which combines the light from two or three 8.2-m Unit Telescopes thereby amounting to observe with a telescope of 40 to 90 metres in diameter, two international teams of astronomers observed with unprecedented detail the environment of two stars. One is a young, still-forming star and the new results provide useful information on the conditions...

Antonio Abetti (June 19, 1846 "“ February 20, 1928) was an Italian astronomer born in San Pietro di Gorizia. He earned a degree in mathematics and engineering at the University of Padua. He Later became director of the Osservatorio Astrofisico di Arcetri (otherwise known as the Arcetri Observatory) and became a professor at the University of Florence. In 1874 Antonio Abetti was part of an expedition led by Pietro Tacchini to observe a transit of Venus with a spectroscope. The crater...
