For the first time in many years, there’s currently a comet visible to the naked eye in Earth’s night sky: comet NEOWISE. For the first time in many years, there’s currently […]
Penguin poop and climate change are fuelling the spread of ‘snow algae’ down the Antarctic Peninsula
As particles travel through the Universe, there’s a speed limit to how fast they’re allowed to go. No, not the speed of light: below it.
In terms of the planets we’ve discovered, super-Earths are by far the most common. What does that mean for the Universe?
Once science operations begin for James Webb, we’ll never look at the Universe the same way again. Here’s what everyone should know.
A new study tracks the human-dog relationship through DNA.

The rings are raining down onto the planet, and disappearing surprisingly fast. 4.5 billion years ago, our Solar System first formed. Protoplanetary disks, which all solar systems are thought to […]
Think there are habitable super-Earths out there? Think again. Here in our Solar System, we have two very distinct types of planets: small, terrestrial, rocky worlds, with thin (or no) atmospheres […]
Big dreams and big telescopes are back at last, but everything depends on sufficiently funding NASA, the NSF, and the DOE.
