Astronomers See Inside A Quasar For The First Time
10-06-2006 · ScienceDailyFor the first time, astronomers have looked inside quasars -- the brightest objects in the universe -- and have seen evidence of black holes. The study lends further confirmation to what scientists have long suspected -- that quasars are made up of super-massive black holes and the super-heated disks of material that are spiraling into them.

- Astronomers find triple interactions of supermassive black holes to be common in early universe
01-08-2007 · EurekAlert!
New cosmological computer simulations produced by a team of astronomers from Northwestern University, Harvard University and the University of Michigan show for the first time that supermassive black holes, which exist at the centers of nearly all galaxies, often come together during triple galaxy interactions. The theoretical results are of special interest because of the recent discovery by astronomers at the California Institute of Technology of a possible triple quasar.

01-10-2008 · EurekAlert!
For the first time astronomers are able to see indirect evidence of dark matter and how this invisible force impacts on the crowded and violent lives of galaxies. University of British Columbia researcher Catherine Heymans has produced the highest resolution map of dark matter ever captured before.

- Astronomers weigh 200-million-year-old baby galaxies
10-25-2006 · EurekAlert!
Astronomers have taken amazing pictures of two of the most distant galaxies ever seen. The ultradeep images, taken at infrared wavelengths, confirm for the first time that these celestial cherubs are real. The researchers are now able to weigh galaxies and determine their age at earlier times than ever before, providing important clues about the evolutionary origins of galaxies like our Milky Way.

- Old idea spawns new way to study dark matter
05-30-2007 · EurekAlert!
An international team of astronomers led by Ohio State University has examined dark matter in the outer reaches of our galaxy in a new way. For the first time, they were able to employ triangulation -- a method rooted in ancient Greek geometry -- to estimate the location of dark matter and calculate its mass.

- Hubble shows 'baby' galaxy is not so young after all
10-16-2007 · EurekAlert!
The NASA/ESA Hubble Space Telescope has found out the true nature of a dwarf galaxy that astronomers had for a long time identified as one of the youngest galaxies in the Universe. Astronomers using the NASA/ESA Hubble Space Telescope have made observations of the galaxy I Zwicky 18 which seem to indicate that it is in fact much older and much farther away than previously thought.

- NASA and Gemini probe mysterious explosion in the distant past
01-08-2008 · EurekAlert!
Using the powerful one-two combo of NASA's Swift satellite and the Gemini Observatory, astronomers have detected a mysterious type of cosmic explosion farther back in time than ever before. The explosion, known as a short gamma-ray burst, took place 7.4 billion years ago, more than halfway back to the Big Bang.

- Rethinking last century's closest, brightest supernova
01-09-2007 · EurekAlert!
February 2007 marks the 20th anniversary of the nearest and brightest supernova humans have seen in 400 years. Called SN1987A, it burned for weeks in the Large Magellanic Cloud, and provided astronomers with new information that forced them to rethink theories of how massive stars explode. Now UC Berkeley astronomer Nathan Smith says that theory needs rethinking again. Exploding stars like SN1987A may have been luminous blue variables, not blue supergiants.
