Results from the Hubble Space Telescope suggest there could be substantial amounts of water on some of the seven, Earth-sized planets orbiting the dwarf star TRAPPIST-1, which is 40 lightyears away, according to a Hubble Space Telescope press release.

Why it matters: Three of these planets fall within Trappist-1's 'habitable zone', which means the planets are the right distance from their star to theoretically support life. When they were discovered earlier this year, scientists suspected there would be water on these planets, but this is the first evidence that it hasn't been all been blown away by the star's radiation.

MIT's Julien de Wit, a co-author on the study: "This concludes that a few of these outer planets could have been able to hold onto some water, if they accumulated enough during their formation. But we need to gather more information and actually see a hint of water, which we haven't found yet."

How it happened: Scientists speculate that the planets were born in the icy outer reaches of their system, and captured water as they were born. When ultraviolet radiation from a star hits a planet's atmosphere, it can break up water there into its constituents oxygen and hydrogen, which can then escape the atmosphere and be detected as an indicator of water. The Hubble researchers used the telescope to measure UV radiation from the star and found that enough was emitted that the inner planets may have lost most of any water that was once there, but three outer planets could still hold water today.

Twitter launches warnings on election misinformation and delays

Twitter will start pinning notices to the top of all U.S. Twitter users’ timelines warning them 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 on Monday, following Senate Democrats' claims that his presence after possible exposure to the coronavirus would be a "violation of common decency," a Pence aide confirmed to CNN and Politico on Monday.

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.
