NASA Says 2020 Was Basically The Hottest Year on Earth Since Records Began

NASA announced Thursday that 2020 was likely the planet's hottest year on record, edging out 2016 by one-tenth of a degree Celsius. The temperatures were close enough to fall within the scientists' margin of error, so they considered it "a statistical tie." Average global temperatures in 2020 were 1.84 degrees Fahrenheit (1 degree Celsius) warmer than in the 30-year average between 1951 and 198

NASA’s New Horizons Measured How Dark Is Space And How Many Galaxies Are Out There

NASA’s New Horizons is billions of kilometers away from the Sun having flown past Pluto and Kuiper Belt Object Arrokoth. This position gives it a unique position to answer an interesting question: how dark is space? And it is probably darker than previously thought. First of all, let’s deal with Olbers’ paradox. Why is the universe dark in the first place? There are stars and galaxies i

Astronomers Find an Astonishing ‘Super-Earth’ That’s Nearly as Old as The Universe

It turns out that planets can live a very long time indeed. Around one of the galaxy's oldest stars, an orange dwarf named TOI-561 just 280 light-years away, astronomers have found three orbiting exoplanets - one of which is a rocky world 1.5 times the size of Earth, whipping around the star on a breakneck 10.5-hour orbit. Obviously an exoplanet so close to its star isn't likely to be habita

Humanity Is Hurtling Into a ‘Ghastly Future’ It Doesn’t Comprehend, Scientists Warn

The emergency is not invisible. But that doesn't mean we can see it. After decades of inaction and ineffective action on biodiversity decline, climate change, and pollution, civilisation stands on the precipice of a "ghastly future" it has gravely underestimated, an international team of scientific experts warns in an unnerving new study published this week. "The scale of the threats to the

Could We Extract Energy From a Black Hole? Scientists Propose a Wild New Plan

For decades, scientists have wrestled with a complex mystery of physics: Could the immense amounts of energy theoretically produced by rotating black holes ever be tapped by human hands? If future societies were somehow able to pull off this magnificent feat, the power supply of far-off galactic civilisations would seemingly be assured - and now scientists have a new explanation for how such an

Astronomers Have Discovered an Alien Planet With Three Suns

To us humans, a single Sun feels completely normal, but our Solar System is actually a weird outlier. Most stars in the Milky Way galaxy have at least one companion star. Now, in a system 1,800 light-years away, astronomers have finally confirmed a gas giant planet orbiting a star in a triple star system. This system, called KOI-5, is located in the constellation of Cygnus, and the exoplanet th
