A New Planet Has Just Been Discovered Orbiting The Nearest Star to The Sun

by

What appears to be a teeny tiny alien world has just been found orbiting the Solar System’s closest stellar neighbor. The exoplanet candidate, named Proxima d, orbits a star named Proxima Centauri: a small, dim red dwarf star just 4.2 light-years from the Sun.   Amazingly, the exoplanet is just a quarter of the mass … Read more

Mysterious Signal of Hidden Lakes on Mars May Not Be What We Thought

by

The likelihood of lakes of liquid water hidden under Mars‘ southern polar ice cap is receding before our very eyes. Last year, a paper found that temperatures were likely far too cold for water to remain unfrozen in the region. Now, a new study has found that the radar signal interpreted as liquid water was … Read more

Scientists Have Detected a Faint Hint of The Background Hum of The Universe

by

Ever since scientists made the first detection of gravitational waves from a pair of colliding black holes in 2015, evidence has been growing that the Universe ought to be full of them.   Every massive event – every black hole or neutron star merger, every supernova – should have sent gravitational waves ringing out across … Read more

Detector designed for gravitational waves seeks signal from dark matter | Science

by

In a feat of scientific repurposing, a team of physicists has used a detector designed to sense gravitational waves—fleeting ripples in space and time set off by, for example, the collisions of two black holes—to search for something even more elusive, dark matter. Although researchers found no sign of the particular hypothetical particles they sought, … Read more
