In my latest video, I talked about how NASA’s TESS recently observed a star shredding black hole. But, TESS stands for “Transiting Exoplanet Survey Satellite” […]
Why is Mendeleev’s table the one we credit for finally bringing the elements together? He wasn’t the first to try, so what was different about his attempt?
In my latest video, I talk about the 100th anniversary of the solar eclipse that propelled Einstein into the public’s eye by providing a test for his general theory of relativity.

Constellations have long been associated with astronomy – understandably, because constellations are found in the night sky, and astronomers study objects found in the night sky. However, one thing I’d like to straighten out – astronomers don’t study the constellations themselves.
In my latest video, I talked about a mysterious object that astronomers have been studying. This object, called AT2018cow has been nicknamed the Cow – but how did this puzzling object get such an unusual name?
In my latest video, I shared information about a pair of rovers bouncing over the surface of an asteroid named Ryugu. The two rovers hitched […]
In my latest video, I talked about how the Gaia mission discovered some “Milky Way interlopers” in our galaxy that were moving differently than expected […]
I find pictures of spiral galaxies to be one of the most beautiful cosmic images. These galaxies are those grand disks of stars with 2 […]
In my latest video, I talk about ring galaxies and how black holes and neutron stars in those rings shine in X-rays. But where do […]
In my latest video, I talk about ring galaxies and how astronomers have found that they originate in collisions of just the right size galaxies […]
