Massive methane leaks mapped from space

by

Using satellite data, researchers have mapped massive plumes of methane released by human activities. Those satellite images revealed that plumes of methane emitted by oil and gas facilities during leaks or maintenance operations made up about 8% to 12% of all oil and gas methane emissions, according to a new study.  “This work confirms what … Read more

Astronomers Keep Finding Stars That Should Be Dead. Now, We May Finally Know Why

by

The most massive stars in the Universe are also the shortest-lived. The more mass a star has, the more quickly it burns through its fuel reserves, resulting in lifespans that are less than around 10 million years.   This fascinating fact leads us to a puzzle. Most of these stars are found relatively close to … Read more

Massive wolf kill disrupts long-running study of Yellowstone park packs | Science

by

Hunters are killing gray wolves in the northern Rocky Mountains in numbers not seen since the animals were driven to near extinction in the continental United States in the 20th century. The killing of more than 750 wolves in Montana, Idaho, and Wyoming in recent months—including nearly 20% of the wolves that roam Yellowstone National … Read more

New Models Let Us Dive Into One of The Brightest Star Explosions We’ve Ever Seen

by

A star that exploded into brightness nearly 200 years ago can now be explored in glorious, multi-wavelength detail. In a new video, a team of scientists modeled the Homunculus Nebula around the star Eta Carinae in three dimensions, enabling insight into this incredible event.   The binary system Eta Carinae started erupting in the late … Read more

The World’s Massive Need For More Solar Panels Has One Shiny Catch

by

There’s a major catch to the world’s need for solar panels, a new analysis suggests. The booming solar panel market – which is critical for a clean energy future – could demand close to half the world’s aluminum by 2050. Thankfully, there are ways we can mitigate this.    Unlike more precious metals, such as … Read more

Astronomers Have Identified a New Kind of Supernova We Never Knew Existed

by

We often think of supernova explosions as inevitable for large stars. Big star runs out of fuel, gravity collapses its core, and BOOM! But astronomers have long thought at least one type of large star didn’t end with a supernova. Known as Wolf-Rayet stars, they were thought to end with a quiet collapse of their core … Read more

Massive asteroid safely zooms by Earth, a million miles away

by

A huge asteroid made its closest approach of the next two centuries Tuesday (Jan. 18), flying quite safely past our planet. Asteroid 7482 (1994 PC1), which is classified as a near-Earth asteroid, only got within five lunar distances of our planet, the equivalent of 1 million miles (1.6 million kilometers). The Virtual Telescope Project, which … Read more

A New Study Calculates The Number of Black Holes in The Universe. It’s a Lot

by

Because we can’t see black holes, it’s hard to know exactly how many are out there in the big, wide Universe. But that doesn’t mean we have no means of trying to figure it out. Stellar-mass black holes are the collapsed cores of dead massive stars, and new research incorporating how these stars and binaries … Read more
