The first spectrum of an extra-solar planet

February 21, 2007
An international colaboration, with participation of the Max Planck Institute for Astronomy in Heidelberg, using NASA's SPITZER Space Telescope, have achieved, for the first time ever, to take a spectrum from an exoplanet.(1) [more]

The Abrupt End of a Young Circumstellar Disk

October 24, 2006
Zooming in on a dusty disk around a nearby young star called HD 141569A with the Subaru telescope on Mauna Kea, Hawaii, astronomers from the National Astronomical Observatory of Japan (NAOJ) and the Max Planck Institute for Astronomy (MPIA)have determined the size of the central hole in ist circumstellar disk. The hole's large size, about the size of the orbit of Saturn, supports the theory that a young star ends its infancy abruptly, ionizing and pushing away the gas in the disk from which it was born.

Astronomers Unite to Make Revolutionary Map and First Movie of the Sky

October 06, 2006
Astronomers from the Max-Planck-Institutes for Astronomy in Heidelberg and for Extraterrestrial Physics in Garching have joined with colleagues world-wide to form a consortium that will exploit a powerful new survey telescope on Haleakala on the island of Maui (Hawaii). This telescope will map repeatedly much of the entire sky, hence creating a very deep color-map and a first digital »movie« of the heavens, mapping changes in the sky with time. [more]

First Direct Evidence Says: Young, very Low Mass Objects Are Twice as Heavy as Predicted

January 23, 2005
Although mass is the most important property of stars, it has proved very hard to measure for the lowest mass objects in the Universe. Thanks to a powerful new camera a very rare low-mass companion has finally been photographed. The discovery suggests that, due to errors in the models, astronomers have overestimated the number of young "brown dwarfs" and "free floating" extrasolar planets. [more]

Mysterious Stellar Dust in the Early Universe

December 23, 2004
Since last year some astronomers thought they finally knew the origin of the large amount of dust surrounding the earliest quasars: It would have formed during supernova explosions of the first stellar generation after the big bang. This notion was inferred from observations of the allegedly "heavily smoking" supernova remnant Cassiopeia A. However, new observations obtained with the ISO and SPITZER infrared satellite observatories now show that this important result is no longer tenable. [more]
