Scientists analyzed iron-rich sedimentary rocks and estimated the amount of oxygen present in the atmosphere when those rocks formed, finding low levels of oxygen and giving insight into a potential biosignature for life beyond Earth.
Recent observations of twelve different stellar streams around the Milky Way have revealed the effects of dark matter, similar to how lights on a Christmas Tree reveal the shape of the tree in dark.
For decades, scientists have been trying to work out just how the Earth got all its water, and the prevailing theory was that comets and asteroids brought it, and we have evidence for that mechanic; however, a new hypothesis has provided evidence that the water was already here, locked away in hydrous minerals in a very iron-poor core.
A dynamical analysis of the 14 Herculis system has revealed the existence of two brown dwarf planets orbiting in completely misaligned, eccentric orbits. The study also uncovered the possibility of a third brown dwarf that was ejected from the system.
By collecting and analyzing stories from a variety of indigenous cultures in North America, researchers find evidence for a mid-air explosion of a comet or asteroid, similar to the Tunguska event
In the latest climate change news, ancient underwater landslides could help us understand tsunami risks in the Middle East, NASA now has a ‘Vanilla’ ice drone to study the Arctic, and lake temperatures are rising
Do you want lasers? I want lasers! And today’s show features lots of lasers. We also have more questions than answers about Mars’ methane, misbehaving stars, and new research on how we would look for the early signs of life on other worlds
The science that dictates our planet is the exact same physics that affects our entire universe. Trying to understand everything around us is just as simple as taking into account all the forces and factors that interact to make everything we see.
Using updated stellar measurements based on new data from the Gaia mission, three (and possibly four) Kepler exoplanets are actually small stars, but it’s unlikely new calculations will reveal many more such issues.
Researchers studying GPS data collected from the 1999 İzmit earthquake in Turkey found that the quake changed the movement of the plate, and this effect may be possible for other tectonic plates.
