Learn all about neutrinos — ghostly, chargeless particles that hardly ever interact with normal matter — in the 14th episode of the astrophysics-explainer video series "We Don't Planet."
Learn all about the parsec, one of the most commonly used distance measurements in astronomy, in the 10th episode of the astrophysics-video series "We Don't Planet."
A primer on dark energy, the mysterious force responsible for the universe's surprising accelerating expansion.
Astronomers use a variety of methods to determine how far away celestial objects are from Earth. Learn about this "cosmic distance ladder" in the ninth episode of "We Don't Planet."
Planets and other celestial bodies can take many types of paths through space. Learn all about the different kinds of orbits in the sixth episode of "We Don't Planet."
The Hertzsprung-Russell diagram allows astronomers to map out the complete life history of a star. Learn all about this famous diagram in the fifth episode of "We Don't Planet."
Dark matter is far more abundant in the universe than the "normal" stuff we can see and touch. Learn about the evidence for dark matter in the fourth episode of "We Don't Planet."
By now, most people have heard the refrain: "The Higgs boson creates mass." But the reality is a bit more complicated than that.
A massive cosmic object can act like a lens, magnifying and warping the images of background bodies. Learn all about this "gravitational lensing" phenomenon in the third episode of "We Don't Planet."
Let's be perfectly honest: The Higgs boson and its role in the universe are not the easiest things to explain.
Dark energy is the mysterious force causing the universe's accelerating expansion. Learn all about it in the second episode of the astrophysics video-explainer series "We Don't Planet."
I don't know about you, but I was shocked when NASA's New Horizons mission sent back its first batch of high-resolution images of the surface of Pluto.
Learn all about the structure of the sun in the first episode of the astrophysics video-explainer series "We Don't Planet."
Humanity has been staring at Saturn's rings for over 400 years, ever since Galileo Galilei first trained his homespun telescope on the mysterious system.
The story of Copernicus' clash with the Church over the arrangement of heavenly bodies is often painted in black and white, but at the time, philosophy, science and religion were all mixed up.
Could we actually warp and bend space-time to make a convenient tunnel, making all our galactic dreams come true? Short answer: not likely.
