An Australian team of astronomers involved in one intense mission of exploration. They succeeded in discovering something quite revolutionary, which involves the Milky Way. The incredible discovery will offer astronomers better insights and understanding.
Team leader, Professor Joss Bland-Hawthorn, worked with the information received by the Hubble Space Telescope. All that he wanted was to get close to a way of understanding the evolution of Milky Way. The team of astronomers identified a cataclysmic energy flare cut through our galaxies some 3.5 million years ago. Professor Bland-Hawthorn stated, “Imagine darkness, and then someone switches on a lighthouse beacon for a brief period.”
This discovery shows how our galaxy’s center was stronger than astronomers thought. Moreover, this fact indicated some new ideas on the evolution of the galaxy.
Astronomers gave further details by explaining how these results will allow the possibility of a whole new reinterpretation of Milky Way’s nature. As Professor Bland-Hawthorn describe the happening, it is “the awakening of the sleeping beauty.”
What Astronomers Know So Far About the Milky Way
Milky Way is, too, described as a suspended spiral galaxy with dimensions that reaches something between 150,000 and 200,000 light-years. It is also full of 100-400 billion stars and approximately 100 billion planets. As for the age of the stars residing in the galaxy, there are many as old as the Universe. The stars are probably created shortly after the Dark Ages or the well-known Big Bang.
Other Recent Discoveries
This year was filled with other significant discoveries. Scientists discover a massive black hole at the center of the Milky Way. The astronomical object named Sagittarius A became unexpectedly active after many years of being inactive. The black hole is estimated to be 4.5 million larger than the Sun itself. It appears that Sagittarius A has a substantial consuming rate of dust, gas, and anything which gets close to it. Andrea Ghez, UCLA Professor of Physics and Astronomy, revealed scientists’ wonder of the phenomenon. She explains that “We have never seen anything like this in the 24 years we have studied the supermassive black hole.”
