In Orion, Herschel finds the youngest stars yet

March 19, 2013
A group of astronomers led by Amelia Stutz of the Max Planck Institute for Astronomy in Heidelberg has used both the Herschel Space Observatory and the submillimeter telescope APEX to discover and characterize the youngest known protostars yet: stellar embryos still deeply embedded in unexpectedly dense dust cocoons. The discovery promises new insights into the earliest stages of star formation, and consequently into the way our home star, the Sun, came into being. The work will be published in the Astrophysical Journal. [more]

Novel approach in hunt for cosmic particle accelerator 

February 14, 2013
A team of astronomers led by Sladjana Nikolić from the Max Planck Institute for Astronomy has observed the supernova remnant SN 1006, probing in unprecedented detail the region where the gas ejected during the supernova meets the surrounding interstellar matter. Such remnants have long been thought to be the source of cosmic ray particles hitting Earth. The observations show, for the first time, the presence of "seed particles", possible precursors of such cosmic rays. The novel approach used by the astronomers promises further insights as to how supernovae remnants act as cosmic particle accelerators. The results will be published on February 14, 2013 in the journal Science. [more]

TW Hydrae: There's more to astronomers' favorite planetary nursery than previously thought

January 30, 2013
Using ESA's Herschel Space Telescope, astronomers including Thomas Henning from the Max Planck Institute for Astronomy in Heidelberg have used a new method to determine the mass of the planetary nursery around the star TW Hydrae. At a distance of merely 176 light-years from Earth, this is the closest star that is currently forming new planets – hence one of the most important objects for astronomers studying planet formation. The precise new measurement shows a much larger mass for TW Hydrae's disk than in previous studies, indicating that the system could be forming planets similar to those of our own Solar System. The study is published in the January 31 issue of the journal Nature. [more]

Giant black hole could upset galaxy evolution models

November 28, 2012
A group of astronomers led by Remco van den Bosch from the Max Planck Institute for Astronomy (MPIA) have discovered a black hole that could shake the foundations of current models of galaxy evolution. At 17 billion times the mass of the Sun, its mass is much greater than current models predict – in particular in relation to the mass of its host galaxy. This could be the most massive black hole found to date. [more]

Rare image of Super-Jupiter sheds light on planet formation

November 19, 2012
An infrared imaging search with the Subaru telescope has captured a rare image of a "Super-Jupiter" around the massive star κ Andromedae. The gas giant has a mass about 13 times that of Jupiter, while the host star has a mass 2.5 times that of the Sun. There are strong indications that this planet formed in a manner similar to ordinary, lower-mass exoplanets: in a "protoplanetary disk" of gas and dust that surrounded the newborn star. This makes the planet an important test case for current models of planet formation and their predictions about planets around massive stars. [more]

CALIFA survey publishes intimate details of 100 galaxies

October 31, 2012
The Calar Alto Legacy Integral Field Area survey (CALIFA survey) has published a first set of data, offering views of one hundred galaxies in the local Universe at an unprecedented level of detail. The new data represent the first large-scale effort at "two plus one" mapping of galaxies: for every pixel within each two-dimensional image, a detailed ("spectral") analysis can be performed, providing information about dynamics and chemical composition. These, in turn, yield key information that will allow scientists to reconstruct the structure and dynamics of galaxies, as well as their evolution over time. [more]

Astronomers pinpoint elusive galaxy after decade-long hunt – and find it's not alone

June 13, 2012
An international team of astronomers led by Fabian Walter of the Max Planck Institute for Astronomy has managed for the first time to determine the distance of the galaxy HDF850.1, well-known among astronomers as being one of the most productive star-forming galaxies in the observable universe. The galaxy is at a distance of 12.5 billion light years. Hence, we see it as it was 12.5 billion years ago, when the universe was less than 10% of its current age. Even more of a surprise, HDF850.1 turns out to be part of a group of around a dozen protogalaxies that formed within the first billion years of cosmic history – only one of two such primordial clusters known to date. The work is being published in the journal Nature. [more]

First instrument for new space telescope JWST completed and handed over to NASA

May 09, 2012
After more than ten years of work by more than 200 scientists and engineers, the MIRI instrument, which will fly on the James Webb Space Telescope (successor to the Hubble Space Telescope) is ready to be shipped to NASA. MIRI, a pioneering camera and spectrograph, is so sensitive it could see a candle on one of Jupiter's moons. Key components of MIRI have been designed and built at the Max Planck Institute for Astronomy in Heidelberg. [more]

A planetary system from the early Universe

March 27, 2012
A group of European astronomers has discovered an ancient planetary system that is likely to be a survivor from one of the earliest cosmic eras, 13 billion years ago. The system consists of the star HIP 11952 and two planets, which have orbital periods of 290 and 7 days, respectively. Whereas planets usually form within clouds that include heavier chemical elements, the star HIP 11952 contains very little other than hydrogen and helium. The system promises to shed light on planet formation in the early universe – under conditions quite different from those of later planetary systems, such as our own. [more]

Recycling galaxies caught in the act

March 14, 2012
When astronomers add up all the gas and dust contained in ordinary galaxies (like our own Milky Way), they find a discrepancy: there is not nearly enough matter for stars to form at the observed rates for long. As a (partial) solution, a matter cycle on gigantic scales has been proposed. In our local galactic neighbourhood, traces of this mechanism had already been found. Now, a study led by Kate Rubin of the Max Planck Institute for Astronomy has found the first direct evidence of such gas flowing back into distant galaxies that are actively forming new stars, validating a key part of "galactic recycling".

First things first – massive stars in W3Main are not born coeval

February 16, 2012
Using the new LUCI-1 instrument at the worlds largest telescope, the Large Binocular Telescope (LBT) in Arizona, astronomers from German institutes detected for the first time that the massive stars in the Galactic star forming region W3Main are not born simultaneously. This discovery has important consequences for our general understanding of the star formation process and the simple picture where stars are born in just a single event is under debate. Over the recent years evidence has been presented that it is more complex in most regions. From this result we now know that stars can form over a time span of several million years [more]

Watching a tiny galaxy grow

February 09, 2012
For the first time, astronomers have caught a so-called dwarf galaxy in the process of swallowing another, even smaller galaxy. Whether such mergers are important for the evolution of the tiniest galaxies has been the subject of debate among theoreticians. Now, thanks to research by two independent groups including MPIA researchers David Martínez-Delgado and Michelle Collins, there is empirical evidence that such mergers occur. The analyses draw on deep images from modestly sized telescopes, in an example for successful collaboration between amateur and professional astronomers. [more]
