Just days after telling the world he still wants to "nuke Mars," SpaceX CEO Elon Musk has slightly walked back the proposal, instead offering a new idea that doesn't use nuclear weapons.
NASA has officially confirmed a mission to Jupiter's moon Europa, a trek that could answer whether the icy celestial body could be habitable for humans and support life.
An invisible substance permeates the universe, altering the paths of stars and galaxies.
Death Valley could reach 120 degrees Fahrenheit as temperatures across a huge swath of the U.S. reach triple digit levels.
The mountain lion P-22, which has been spotted traveling across Los Angeles freeways and spending time in parks, has become something of a legend in California.

Earlier this month, the U.S. pulled out of a Reagan-era nuclear treaty with Russia after the Trump administration assessed the country was in “material breach of the treaty” and made no effort to “come back into compliance.” If there were any kind of escalation between the two countries that would result in a nuclear war, it would almost certainly end in a nuclear winter, according to a new study.
India's Chandrayaan-2 spacecraft has entered the Moon's orbit, the country’s space agency announced Tuesday.
Months after Hurricane Michael bruised the panhandle and Irma slammed into the Florida Keys, the community is bracing themselves for what comes next. One scientist with the Florida Gulf Coast University is digging for those answers underwater with a technique called coring. It involves digging in the dirt underwater to uncover information about hurricanes from thousands of years ago, that can help predict how strong future hurricanes will be. She predicts severe hurricanes ahead, matching up with the latest National Oceanic and Atmospheric Administration forecasts.
Extreme weather conditions may be encouraging an increase in angry spiders populations, according to a new study.

More than 11,000 waterfowl and wetland birds were killed or maimed after “baseball-sized” pieces of hail wreaked havoc over a Montana wildlife management area last weekend during a storm, state officials said Friday.
Neutrinos are perhaps the most underrated particles known to humankind. Physicist, smart guy and smart aleck Wolfgang Pauli first proposed their existence in 1930 as a missing puzzle piece — certain nuclear reactions had more going in than they had coming out. Pauli reasoned that something tiny and invisible had to be involved — hence, the neutrino, which is kind of Italian for "little neutral one."
Humans played a much bigger role than previously thought in driving the cave bear to extinction, according to new evidence.

Plastic pollution found in the world's oceans and the melting permafrost in the Arctic could have startling economic burdens, perhaps as much as $2.5 trillion and $70 trillion, respectively.
