Royal Astronomical Society (RAS) Astronomers investigating behavior of the universe shortly after the Big Bang have made a surprising discovery: the properties of the early universe are determined by the smallest galaxies. The team report their findings in a paper published today in the journal Monthly Notices of the Royal Astronomical Society. Shortly after the Big Bang, the universe was ionized: ordinary matter consisted of hydrogen with its positively charged protons stripped of...

Ultra-cool Brown Dwarf Helps Reveal Giant Planets
2012-05-11 02:57:58

An international team of astronomers led by David Pinfield of the University of Hertfordshire has found a brown dwarf that is more than 99% hydrogen and helium. Described as ultra-cool, it has a temperature of just 400 degrees Celsius and its discovery could be a key step forward in helping astronomers distinguish between brown dwarfs and giant planets. The researchers publish their work in the journal Monthly Notices of the Royal Astronomical Society. Brown dwarfs are star-like objects...

Image 1 - Milky Way’s Companions May Spell Trouble For Dark Matter
2012-04-25 07:46:27

Astronomers from the University of Bonn in Germany have discovered a vast structure of satellite galaxies and clusters of stars surrounding our Galaxy, stretching out across a million light years. The work challenges the existence of dark matter, part of the standard model for the evolution of the universe. PhD student and lead author Marcel Pawlowski reports the team´s findings in a paper in the journal Monthly Notices of the Royal Astronomical Society. The Milky Way, the galaxy we...

Bright Andromeda Object Caused By 'Normal' Black Hole
2012-02-24 04:24:28

A spectacularly bright object recently spotted in one of the Milky Way's neighboring galaxies is the result of a "normal" stellar black hole, astronomers have found. An international team of scientists, led by Dr Matt Middleton, of Durham University, analyzed the Ultraluminous X-ray Source (ULX), which was originally discovered in the Andromeda galaxy by NASA's Chandra x-ray observatory. They publish their results in the journals Monthly Notices of the Royal Astronomical Society and...

Researchers Discover Sold-State Buckyballs In Space
2012-02-22 13:38:19

[ Watch the Video ] For the first time ever, astronomers have discovered buckminsterfullerines existing in a solid form in space, according to a study published in the journal Monthly Notices of the Royal Astronomical Society. Ian O'Neill of Discovery News reports that buckminsterfullerines (also known as buckyballs) are "a geodesic molecular ordering of 60 carbon atoms that resemble the domes designed by American architect and inventor Richard Buckminster Fuller." Previously, these...

Image 1 - Do Black Holes Help Stars Form?
2012-02-03 08:27:06

The center of just about every galaxy is thought to host a black hole, some with masses of thousands of millions of Suns and consequently strong gravitational pulls that disrupt material around them. They had been thought to hinder the birth of stars, but now an international team of astronomers studying the nearby galaxy Centaurus A has found quite the opposite: a black hole that seems to be helping stars to form. The team, led by Dr Stanislav Shabala of the University of Tasmania, Dr Mark...

Image 1 - A Tale Of Tails
2011-12-07 04:46:52

An international group of astronomers led by Tom Scott at the Instituto de Astrofísica de Andalucía in Granada, Spain, has discovered extraordinarily long one-sided gaseous tails in two groups of galaxies that are amongst the longest structures ever observed in such environments. They emanate from CGCG 097-026 and FGC1287, two spiral galaxies in small groups in the outskirts of the galaxy cluster known as Abell 1367 in the constellation of Leo, at a distance of 300...

Supermassive Black Holes Smash Planets To Dust
2011-10-28 10:15:33

Fat doughnut-shaped dust shrouds that obscure about half of supermassive black holes could be the result of high speed crashes between planets and asteroids, according to a new theory from an international team of astronomers. The scientists, led by Dr. Sergei Nayakshin of the University of Leicester, publish their results in the journal Monthly Notices of the Royal Astronomical Society. Supermassive black holes reside in the central parts of most galaxies. Observations indicate that about...

Researchers Explain How The Milky Way Killed Off Its Satellites
2011-10-18 08:09:33

Two researchers from Observatoire Astronomique de Strasbourg have revealed for the first time the existence of a new signature of the birth of the first stars in our galaxy, the Milky Way. More than 12 billion years ago, the intense ultraviolet light from these stars dispersed the gas of our Galaxy's nearest companions, virtually putting a halt to their ability to form stars and consigning them to a dim future. Now Pierre Ocvirk and Dominique Aubert, members of the Light in the Dark Ages of...

How Did Single Stars Lose Their Companions
2011-09-16 07:12:23

  Not all stars are loners. In our home galaxy, the Milky Way, about half of all stars have a companion and travel through space in a binary system. But explaining why some stars are in double or even triple systems while others are single has been something of a mystery. Now a team of astronomers from Bonn University and the Max-Planck-Institute for Radio astronomy (also in Bonn) think they have the answer — different stellar birth environments decide whether a star holds on to...

The Astronomical Journal (AJ) is a peer-reviewed scientific journal ran by the American Astronomical Society and published monthly by the Institute of Physics Publishing. It is one of the premier astronomy journals in the world. It was published by the University of Chicago Press until 2008. The society also owns the Astrophysical Journal. The journal was established in 1849 by Benjamin A. Gould. In 1861, publication was ceased due to the American Civil War. It went unpublished until 1885....
