Birth of Star S106 IR Birth: Emerging from a cloud of gas and dust called a nebula, a star forms when gravity pulls hydrogen gas from the nebula together and spins it around at such a fast rate that it heats up. This creates what is known as a “protostar”. Once the soon-to-be star’s temperature … Continue reading The Life of Low Mass Stars → Continue reading → Continue reading
Johannes Kepler was born on Dec. 27, 1571 and died on May 21, 1630. He was important to astronomy because he made 3 key astronomical discoveries. First, and arguably most importantly, he discovered that planetary orbits are ellipses and not perfect circles as is it was popularly believed to be at the time. This was … Continue reading Historical Astronomers in Context → Continue reading → Continue reading
