North Korea's foreign minister told CNN the U.S. should take Kim Jong-un's threat of detonating a nuclear weapon "literally." He emphasized he "is very well aware of the intentions of" Kim. North Korea threatened a little over a month ago to detonate a hydrogen bomb over the Pacific Ocean, but hasn't yet.

Why it matters: Hydrogen bombs have never been used in warfare before — they would devastate the environment and public health and are more powerful than atomic bombs. And North Korea has been threatening actions over the last few months, and then following up on them.

North Korea carried out its strongest nuclear test yet last month, using what it said was a missile-ready hydrogen bomb.

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning that results in next week’s election may be delayed and that they may encounter misinformation on mail-in voting.

Why it matters: Delayed election results are expected across many states that are handling unprecedented amounts of absentee and mailed ballots, which President Trump has baselessly called "very dangerous" and "corrupt."

NASA confirms water exists on sunny parts of the Moon


Water on the Moon might be more easily accessible than previously thought, opening up new possible avenues for future human exploration, according to a new study.

Why it matters: NASA is aiming to send people back to the Moon as part of its Artemis program by 2024, with plans to eventually create a sustainable presence on the lunar surface. That sustainability relies on mining the moon for its resources, like water.

Vice President Mike Pence no longer plans to attend the Senate's final confirmation vote for Judge Amy Coney Barrett, a Pence aide confirmed to CNN and Politico on Monday. On Sunday, Senate Democrats claimed that his presence after possible exposure to the coronavirus would be a "violation of common decency."

Driving the news: Five of Pence's aides were recently diagnosed with COVID-19, including his chief of staff, who is currently quarantining. Pence has continued his campaign travel despite his possible exposure, which goes against CDC guidelines.
