A presentation at the June 6th AAS meeting confirms that our galaxy is inside an enormous cosmic void, the largest one ever discovered.
Astronomers have discovered a giant cosmic void that explains why our Local Group of galaxies is moving through the universe as fast as it is.
Although there are no seasons in space, this cosmic vista invokes thoughts of a frosty winter landscape. It is, in fact, a region called NGC 6357 where radiation from hot, young stars is energizing the cooler gas in the cloud that surrounds them.
An international team of astronomers has discovered a previously unknown major concentration of galaxies in the constellation Vela, which they have dubbed the Vela supercluster.
Using two of the world's largest configurable telescopes, scientists have created the most detailed map yet of hydrogen atoms the Milky Way.
The X-ray emissions were discovered by chance beyond the Milky Way and no one really knows what is causing them.
A star with the unassuming name of KIC 8462852 in the constellation Cygnus has been raising eyebrows both in and outside of the scientific community for the past year.
The European Space Agency is set to unveil a three-dimensional map of a billion stars in our galaxy that is 1,000 times more complete than anything existing today.
Dragonfly 44, as it has been named, is roughly the same size as our Milky Way but with far fewer stars. Rather, the galaxy appears to be composed largely of dark matter, which does not emit light or interact with electromagnetic radiation.
Discovery of a time-resolved supernova signal in Earth's microfossils. According to the researcher's analyses, our solar system spent one million years to transit trough the remnants of a supernova.
A major revision is required in our understanding of our Milky Way Galaxy. Astronomers have found that there is a huge region around the center of our own galaxy, which is devoid of young stars.
Astronomers working with the European Space Agency's (ESO) Very Large Telescope (VLT) in Chile have just announced that a black hole-observing device called GRAVITY is now fully operational and it's has already provided one accurate measurement.
The Milky Way, the brilliant river of stars that has dominated the night sky and human imaginations since time immemorial, is but a faded memory to one third of humanity according to a new global atlas of light pollution.
A spectacular image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL).
New Hubble telescope observations suggest that a high-velocity gas cloud was launched from the outer regions of our own galaxy around 70 million years ago. Now, the cloud is on a return collision course and is expected to plow into the Milky Way's disk in about 30 million years.
