Not all the Earth’s Water Came From Comets
2018-11-09
Not all the Earth’s Water Came From Comets We have comets and asteroids to thank for Earth’s water, according to the most widely-held theory among scientists. But it’s not that cut-and-dried. It’s still a bit of a mystery, and a new study suggests that not all of Earth’s water was delivered to our planet that way. Hydrogen is the most abundant element in … Continue reading “Not all the Earth’s Water Came From Comets” The post Not all the Earth’s Water Came From Comets appeared first on Universe Today.

We Could Build a Powerful Laser and Let Any Civilizations Within 20,000 Light-Years Know We’re Here. Although… Should We? A powerful laser is just the thing to announce our presence as a technological species in this arm of the galaxy. Engineers would line up to work on that project. But is it a good idea to let any mysterious galactic neighbours know we’re here?

Astronomers find pairs of black holes at the centers of merging galaxies
2018-11-07
For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of gas and dust surrounding the merging galaxies’ messy cores, the research team captured pairs of supermassive black holes—each of which once occupied the center of one of the two original smaller galaxies—drawing closer together before they coalescence into one giant black hole.
