Gas Stoves Leak More Methane than Previously Thought

by

A new study is reporting a larger climate impact from gas stoves than previously thought, stoking a debate about one of the largest sources of greenhouse gas emissions: buildings. Published by a team of four Stanford University Earth-system scientists today in the peer-reviewed journal Environmental Science & Technology, the study concluded that U.S. gas stoves could … Read more

‘Killer Lake’ in Africa Looks Like Paradise, But It’s Hiding a Deadly Secret

by

The engineers aboard the floating power station on Lake Kivu could only watch nervously as the volcano in the distance erupted violently, sending tremors rumbling through the water beneath them.   It was not the lava shooting from Mount Nyiragongo last May that spooked them, but the enormous concentrations of potentially explosive gases within Kivu, … Read more

Gas Giants: Facts About the Outer Planets

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.  These four large planets reside in the outer part of the solar system past the orbits of Mars and the … Read more

Physicists Just Smashed a Record by Keeping a Bubble Intact For Over a Year

by

When you think of the word “ephemeral”, many people will immediately conjure up the image of a soap bubble: delicate, gorgeous, and gone in a blink (or maybe a few). Now a team of physicists led by Aymeric Roux of the University of Lille in France has defied this cliché, creating a bubble that maintained … Read more

Local Bubble: Huge gas structure that contains the solar system mapped for first time

by

The solar system lies inside a structure called the Local Bubble some 1000 light years across – and a map of its surface shows it is the site of star formation Space 12 January 2022 Artist’s illustration of the Local Bubble with star formation occurring on the bubble’s surface Leah Hustak (STScI) The star-forming regions … Read more

The Solar System Exists Inside a Giant, Mysterious Void, And We Finally Know Why

by

The Solar System floats in the middle of a peculiarly empty region of space. This region of low-density, high-temperature plasma, about 1,000 light-years across, is surrounded by a shell of cooler, denser neutral gas and dust. It’s called the Local Bubble, and precisely how and why it came to exist, with the Solar System floating … Read more
