Jovian Auroral Discord
At the end of October a team of astronomers led by the University College London published a paper in Nature Astronomy reporting they had discovered that planet Jupiter’s northern and southern aurorae emit pulses of X-rays independently of each other. They made this discovery by analyzing data gathered by the ESA’s XMM-Newton and NASA’s Chandra X-ray observatories in May-June 2016 and March 2007. The astronomers observed that the X-ray emissions at the north pole were erratic […]
Third time is not the charm for LIGO gravitational wave discovery
I wasn’t sure what more I could write to follow up on my article concerning the second gravitational wave discovery claim by the LIGO team that I posted exactly one year ago today. Instead of hundreds or even dozens of subsequent detections that were predicted to be made since that time, there has been only one! This third detection, GW170104, occurred over a year after the second one and is the weakest and least precise […]

2016: The year of the missing dark matter
For years researchers have tried to detect dark matter and failed and this past year was no exception. Dark matter is made of elusive particles that supposedly make up approximately 27% of all matter and over five times the amount of normal matter in the known universe. The concept of dark matter came about almost fifty years ago when astronomers discovered that the stars and gas in the galaxies they observed all rotated around their galactic centers at […]
