Highly Active Galaxies in the Very Early Universe Found

  Record-breaking haul of distant galaxies includes most distant detection of water published to date   Observations with the Atacama Large Millimeter/submillimeter Array (ALMA) show that the most vigorous bursts of star formation in the cosmos took place much earlier than previously thought. The results are published in a set of papers to appear in the [continue reading]

How a Young Star and its Planets Grow Simultaneously

  Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have seen a key stage in the birth of giant planets for the first time. Vast streams of gas are flowing across a gap in the disk of material around a young star. These are the first direct observations of these streams, which are expected [continue reading]

Brown Dwarfs May Host Rocky Earth-Like Planets

  Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have for the first time found that the outer region of a dusty disk encircling a brown dwarf contains millimeter sized solid grains like those found in denser disks around newborn stars. The surprising finding challenges theories of how rocky, Earth-size planets form, and suggests that rocky planets [continue reading]

Chances to Find Intelligent Life Increased by New Telescopes

  How do planetary systems form? What do the surfaces of stars look like? Does life exist elsewhere in the Universe? Astronomers have developed many theoretical models, but until now the ability to validate these with observations has been severely constrained by the telescope capabilities available. Dust ring around the star Fomalhaut is seen by [continue reading]

Surprising Spiral Structure Found Around Red Giant Star

  Astronomers have discovered a totally unexpected spiral structure in space. The strange shape, discovered in gas and dust surrounding the red giant star R Sculptoris, was probably created by a hidden companion star orbiting the star. The research, which appears in the journal Nature this week, gives new insight on how stars like the [continue reading]

Studying the Chemistry of the Universe with ALMA

  Combining the cutting-edge capabilities of the ALMA telescope with newly-developed laboratory techniques, scientists are opening a completely new era for deciphering the chemistry of the Universe. A research team demonstrated their breakthrough using ALMA data from observations of the gas in a star-forming region in the constellation Orion. Hubble’s sharpest view of the Orion [continue reading]
