2013-03-27 09:17:50

Max Planck Institute for Radio Astronomy An international team of astronomers, including researchers from the Max Planck Institute for Radio Astronomy and from the University of Cologne, discovered two titanium oxides, TiO and TiO2, at radio wavelengths using telescope arrays in the USA and in France. The detection was made in the environment of VY Canis Majoris, a giant star close to the end of its life. The discovery was made in the course of a study of a spectacular star, VY Canis...

Millisecond Pulsars: The Discovery Of Deceleration
2012-02-03 08:16:23

Stellar astrophysics helps to explain the behavior of fast rotating neutron stars in binary systems Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometers, but at the same time roughly the mass of our sun. A sugar-cube sized piece of its ultra-compact matter on the Earth would weigh hundreds of millions of tons. A sub-class of them, known as millisecond pulsars, spin up to several hundred times per second around their own axes. Previous...

A New Atlas Of The Milky Way

  Sino-German research group draws a new map at the Urumqi radio telescope and discovers two supernova remnants It may not be much use to hitchhikers through the galaxy, but it is extremely valuable to astronomers: the new radio atlas of the Milky Way. After almost ten years of work, researchers at the Max Planck Society and the Chinese Academy of Sciences have completed their investigation into the polarized radio emission in the galactic plane. The atlas is based on observations...

Molecules of hydrogen peroxide have been found for the first time in interstellar space. The discovery gives clues about the chemical link between two molecules critical for life: water and oxygen. On Earth, hydrogen peroxide plays a key role in the chemistry of water and ozone in our planet's atmosphere, and is familiar for its use as a disinfectant or to bleach hair blonde. Now it has been detected in space by astronomers using the ESO-operated APEX telescope in Chile. An international team...

WASHINGTON, April 7, 2011 /PRNewswire-USNewswire/ -- The Stratospheric Observatory for Infrared Astronomy, or SOFIA, completed its first science flight Wednesday, April 6, using the German Receiver for Astronomy at Terahertz Frequencies (GREAT) scientific instrument. GREAT is a high-resolution far-infrared spectrometer that finely divides and sorts light into component colors for detailed analysis.

An international team of astronomers, led by Keiichi Ohnaka at the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, has made the most high resolution images of a dying giant star to date. For the first time they could show how the gas is moving in different areas over the surface of a distant star. This was made possible by combining three 1.8 meter telescopes as an interferometer, giving the astronomers the resolving power of a virtual, gigantic 48 meter telescope. Using the ESO VLT...

Astronomers have unveiled an unprecedented new atlas of the inner regions of the Milky Way, our home galaxy, peppered with thousands of previously undiscovered dense knots of cold cosmic dust "” the potential birthplaces of new stars. Made using observations from the APEX telescope in Chile, this survey is the largest map of cold dust so far, and will prove an invaluable map for observations made with the forthcoming ALMA telescope, as well as the recently launched ESA Herschel space...

Scientists in the US and Germany have discovered two of the most complex molecules ever to be found in space, and their scientific models imply that even larger molecules, such as amino acids, may also exist. Scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, Cornell University in the US, and the University of Cologne in Germany have reported the discovery of ethyl formate and n-propyl cyanide in space. Using the IRAM 30 m telescope in Spain, the team discovered...

Illustrating the power of submillimeter-wavelength astronomy, an APEX image reveals how an expanding bubble of ionized gas about ten light-years across is causing the surrounding material to collapse into dense clumps that are the birthplaces of new stars. Submillimeter light is the key to revealing some of the coldest material in the Universe, such as these cold, dense clouds. The region, called RCW120, is about 4200 light years from Earth, towards the constellation of Scorpius. A hot,...

Researchers from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn have detected for the first time a molecule closely related to an amino acid: amino acetonitrile. The organic molecule was found with a 30 meter radio telescope in Spain and two radio interferometers in France and Australia in the "Large Molecule Heimat", a giant gas cloud near the galactic centre in the constellation Sagittarius (Astronomy & Astrophysics, in press).The "Large Molecule Heimat" is a very dense,...
