This week is the 100th anniversary of Einstein’s theory of general relativity. On November 25, 1915, Einstein published the field equations of gravity which are the heart of the general relativity. Sure, you’ve heard of Einstein – he was a smart guy. And you’ve probably heard of general relativity, but … Continue Reading →

  • Comments Off on How Do We Know It: Supernova Remnant Age

I get a lot of inspiration for blog-topics from questions I get via email. Often they don’t have easy or straightforward answers (see this question on how many stars there are in the Milky Way). I was recently asked how we arrived at an age of 8000 years for the … Continue Reading →

In space, no one can hear you scream. Any sci-fi buff worth their dilithium crystals knows why: sound requires a medium such as air or water in which to propagate and empty space is well, empty. But what if I told you that there are waves that can travel through … Continue Reading →

Note: A childhood friend of mine came for a visit this summer with her science-obsessed seven-year-old, Oren. He was so taken with what he saw that he wanted a James Webb Space Telescope (JWST) costume for Halloween. They did such a nice job with it (and the accompanying Ariane 5 … Continue Reading →

GRB all-sky map

Back to School with GRB 101

Up until a few years ago, gamma-ray bursts (or GRBs, for short) were arguably the biggest mystery in high-energy astronomy. Basically, gamma-ray bursts are brief, extremely bright bursts of gamma-rays (as the name implies). They appeared at random across the sky. But what are they? What causes that burst? And … Continue Reading →
