What a roller coaster week it’s been. If partial eclipses and giant sunspots aren’t your thing, how about a close flyby of an Earth-approaching asteroid? 2014 SC324 was discovered on September 30 this year by the Mt. Lemmon Survey high in the Catalina Mountains north of Tucson, Arizona. Based on brightness, the tumbling rock’s size is estimated at […]
The number of protons defines an element, but the number of neutrons can vary. We call these different flavors of an element isotopes, and use these isotopes to solve some challenging mysteries in physics and astronomy. Some isotopes occur naturally, and others need to be made in nuclear reactors and particle accelerators.
