‘We are teetering on a planetary tightrope’: Cut emissions in half right now to prevent climate catastrophe, UN warns
Global temperatures will soar to 3.1 degrees Celsius (5.6 degrees Fahrenheit) above preindustrial levels by 2100 if governments don't set more ambitious climate targets, a new United Nations (U.N.) report warns.Warming on this scale is more than twice the 1.5 C (2.7 F) target outlined in the 2015 Paris Agreement — a legally binding treaty
Planetary Scientists Find Large Granite Formation on Moon’s Far Side
The 50-km-diameter granitic system discovered below the far side feature known as Compton-Belkovich Volcanic Complex likely was formed from the cooling of molten lava that fed a volcano or volcanoes that erupted approximately 3.5 billion years ago. This illustration shows the Compton-Belkovich Volcanic Complex (CBVC) on the Moon’s far side and the boxed area indicated
Planetary Debris Spotted around 11-Billion-Year-Old White Dwarf
WD J2147-4035, an 11-billion-year-old white dwarf located 91 light-years away in the constellation of Grus, is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in our Milky Way Galaxy. An artist’s impression of the white dwarfs WD J2147-4035 and WD J1922+0233 surrounded by orbiting planetary debris, which
