But at least one of them was ejected from the comparatively calm galactic disk, a discovery that has astronomers rethinking this whole star ejection
The phrase “mass extinction” typically conjures images of the asteroid crash that led to the twilight of the dinosaurs. Upon impact, that 6-mile-wide space rock caused a tsunami in the Atlantic Ocean, along with earthquakes and landslides up and down what is now the Americas.

We often think of Venus as our closest Solar System sibling. It’s the most similar to Earth in size, mass and composition. And we thought it was the closest in terms of physical distance – but it looks like that honour could belong to Mercury. No, the order of the planetary orbits is still the
As the frozen Antarctic landscape at the bottom of the world adjusts to an ever hotter planet, we keep finding more mysterious phenomena beneath and within the ice. Now, there are “ice quakes” to add to that list. It wasn’t all so long ago that earthquakes were thought to not exist on this unforgiving continent.

Tests show that dormant herpes viruses reactivate in more than half the astronauts who travel on the Space Shuttle and International Space station, according to new NASA research – a phenomenon the space agency says could pose problems for deep space missions. “During spaceflight there is a rise in secretion of stress hormones like cortisol
The collision of the Milky Way and Andromeda Galaxies. Not graphs, but close.NASA For most of us, the word graph brings back memories (not always pleasant) of pencils and rulers and quadrille ruled paper, though a more recent generation may think instead of pie and bar charts produced in Excel from spreadsheets.
