Researchers using NASA’s Chandra X-ray Observatory have found evidence that the normally dim region very close to the supermassive black hole at the center of the Milky Way Galaxy flared up with at least two luminous outbursts in the past few hundred years.
This discovery comes from a new study of rapid variations in the X-ray emission from gas clouds surrounding the supermassive black hole, a.k.a. Sagittarius A*, or Sgr A* for short. The scientists show that the most probable interpretation of these variations is that they are caused by light echoes

At one glance, one may think that this image is photoshopped or it’s a composite because it’s simply impossible to see Milky Way galaxy at dusk. But what you’re really seeing here is a single exposure shot of a rare phenomenon, known as zodiacal light (a.k.a. “false dusk”), that I have captured during my recent trip to Mount Bromo in the Southern Hemisphere. Zodiacal light is best seen during spring and autumn, and I chose to visit Mt Bromo a few days after [the Southern Hemisphere's autumnal equinox] as I hoped to capture the zodiacal light along with the 3 planets, 3 volcanoes and a Milky Way galaxy.
Last week at the latest TEDGlobal conference in Oxford, astronomer Dimitar Sassilov, professor of astronomy at Harvard University and a distinguished member of the Kepler space telescope [1] science team, unveiled some incredible results gathered by our eyes and ears in the galaxy.
Kepler’s most recent reported downloaded conferred some incredible statistics, among which most importantly the discovery of: 706 potential new planets and five new solar systems, all found within the 150,000+ stars Kepler has studied so far since its 4 year mission began January last year.
Shifting cosmic winds suggest that our solar system lives in a surprisingly complex and dynamic part of the Milky Way galaxy, a new study reports.
Scientists examining four decades' worth of data have discovered that the interstellar gas breezing through the solar system has shifted in direction by 6 degrees, a finding that could affect how we view not only the entire galaxy but the sun itself.
Our Milky Way smashed into its neighbouring Andromeda galaxy around 10 billion years ago, European astronomers suggest.
Previous studies have suggested that our galaxy is set to crash into Andromeda in 3-4 billion years, and that this will be the first time such a collision has taken place.
However, now a European team of astronomers led by Hongsheng Zhao of the University of St Andrews propose that the two star systems collided some 10 billion years ago and that our understanding of gravity is fundamentally wrong.
This would neatly explain the observed structure of the two galaxies and their satellites, something that has been difficult to account for until now, researchers said.
This image from NASA's Galaxy Evolution Explorer shows NGC 6744, one of the galaxies most similar to our Milky Way in the local universe. This ultraviolet view highlights the vast extent of the fluffy spiral arms, and demonstrates that star formation can occur in the outer regions of galaxies. The galaxy is situated in the constellation of Pavo at a distance of about 30 million light-years.
NGC 6744 is bigger than the Milky Way, with a disk stretching 175,000 light-years across. A small, distorted companion galaxy is located nearby, which is similar to our galaxy's Large Magellanic Cloud. This companion, called NGC 6744A, can be seen as a blob in the main galaxy's outer arm, at upper right.
Our home in the Milky Way could be much larger than ever thought before, according to a new study.
Astronomers using the National Science Foundation's Very Long Baseline Array (VLBA) found that the area of the galaxy that holds Earth and the rest of the solar system is a prominent feature of the spiral galaxy.
The solar system exists in a part of the galaxy known as the Local Arm. Until now, scientists thought that this particular part of the Milky Way was just a tiny spur between two large branches known as the Sagittarius and Perseus arms.

What would you do if you weren't afraid? This is the message of Sion...To overcome our fear..connect with our higher self..operate from that finer, higher place...NOW is the time for us to do this. To put away our fear, overcome our limitations and become the true Divine humans we know we can become..
Much Peace, Joy, Light and Love to ALL! NOW! :) <3
