We’re putting more and more satellites into orbit, and along with all the welcome technological and scientific advances that brings, there are also potential problems. Intended to be the start of an orbiting communications network that can be accessed by standard smartphones, the recently launched prototype BlueWalker 3 satellite is now one of the brightest

Earth is about 29 percent land and 71 percent oceans. How significant is that mix for habitability? What does it tell us about exoplanet habitability? There are very few places on Earth where life doesn’t have a foothold. Multiple factors contribute to our planet’s overall habitability: abundant liquid water, plate tectonics, bulk composition, proximity to

Is there anything good about volcanoes? They can be violent, dangerous, and unpredictable. For modern humans, volcanoes are mostly an inconvenience, sometimes an intriguing visual display, and occasionally deadly. But when there’s enough of them, and when they’re powerful and prolonged, they can kill the planet that hosts them. Modern-day Venus is a blistering hellscape.

Rising levels of carbon dioxide in Earth’s atmosphere could exacerbate efforts to clean up our increasingly cluttered shell of orbiting space junk. According to two new studies, the greenhouse gas has significantly contributed to the contraction of the upper atmosphere. This contraction has been hypothesized for decades; now, for the first time, it’s been actually

The first galaxies may have formed far earlier than previously thought, according to observations from the James Webb Space Telescope that are reshaping astronomers’ understanding of the early universe. Researchers using the powerful observatory have now published papers in the journal Astrophysical Journal Letters, documenting two exceptionally bright, exceptionally distant galaxies, based on data gathered

Hypothetical bridges connecting distant regions of space (and time) could more or less look like garden variety black holes, meaning it’s possible these mythical beasts of physics have already been seen. Thankfully however, if a new model proposed by a small team of physicists from Sofia University in Bulgaria is accurate, there could still be

Today, the number of confirmed exoplanets stands at 5,197 in 3,888 planetary systems, with another 8,992 candidates awaiting confirmation. The majority have been particularly massive planets, ranging from Jupiter and Neptune-sized gas giants, which have radii about 2.5 times that of Earth. Another statistically significant population has been rocky planets that measure about 1.4 Earth
