Johannes Kepler: Mathematician, Mystic… Murderer?

May 5, 2016 by Brian Ventrudo Filed Under: History and Famous Astronomers

The progress of science sometimes comes down to an unlikely partnership, a combination of the right people studying the right problem at the right time. In the pantheon of unlikely partners, few can top the team of Johannes Kepler and Tycho Brahe, two men of polar-opposite personalities who finally cracked the secret of the motion of the planets. Here is their story [Read more…] about Johannes Kepler: Mathematician, Mystic… Murderer?

The usually reliable Eta Aquarid meteor shower runs from April 21 – May 20, 2016, with many meteors still visible for several days on either side of the peak on May 5-6, 2016. This is perhaps the best meteor shower of the year for southern hemisphere stargazers [Read more…] about Eta Aquarid Meteor Shower – 2016

The planet Mercury will appear to pass across the face of the Sun on Monday, May 9, 2016. This event, known as a transit, will be visible in a small telescope with a proper solar filter from much of North and South America, Africa, and western Europe. It’s a great opportunity to see the mechanics of the solar system in action and to spot the elusive inner planet as it passes across the blazing solar disk [Read more…] about A Guide to the Transit of Mercury on May 9, 2016

Sun Unexpectedly Swells to Red Giant

April 1, 2016 by Brian Ventrudo Filed Under: Stargazing

The Sun unexpectedly has swollen to a red-orange on April 1, 2016 as seen over southern California.
The Sun unexpectedly has swollen to a red-orange on April 1, 2016 as seen over southern California.

In a development that has shocked astrophysicists around the world, the Sun has unexpectedly run out of hydrogen fuel in its core. As gravity squeezed the collapsing core, the dense plasma increased in temperature and ignited helium burning, causing the outer layers to swell into a red giant. Reports suggest the two inner planets, Mercury and Venus, have been swallowed by the expanding star. On Earth, students in the northern hemisphere have been released from school to start summer break early. While astronomers are perplexed, health professionals strongly recommend a thick layer of sunscreen for anyone venturing outside, at least until someone can figure out how to restock the supply of hydrogen gas in the Sun’s core.

In a media report, Professor Cedric Doppleganger, of the California Institute of Astrophysics, said that although the Sun’s sudden expansion violates all known laws of physics, that researchers are undeterred. “It just goes to show that the science of solar physics isn’t so settled after all.”

Total Solar Eclipse on March 9, 2016

March 3, 2016 by Brian Ventrudo Filed Under: Celestial Events, Solar System

SE2016Mar09T
Path of the solar eclipse of March 8-9, 2016.

The year’s only total solar eclipse occurs next week on March 8-9, 2016. The narrow path of totality runs from the eastern Indian Ocean, across the islands of Sumatra, Borneo, Sulawesi, and on into the Pacific Ocean north of Hawaii. Armadas of ships carrying astronomical tourists are on the way to the area, especially to the region of maximum totality well north of Papua New Guinea where the eclipse will last an impressive 4 minutes. For readers of this site on the way to see this magnificent event, I wish you clear skies and calm seas [Read more…] about Total Solar Eclipse on March 9, 2016
