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.

The incoming Biden administration will reverse President Trump's last-minute order to lift COVID-19 related travel restrictions, Jen Psaki, the incoming White House press secretary, tweeted.

Why it matters: President Trump ordered entry bans lifted for travelers from the U.K., Ireland, Brazil and much of Europe to go into effect Jan. 26, but the Biden administration will "strengthen public health measures around international travel in order to further mitigate the spread of COVID-19," Jen Psaki said. Biden will be inaugurated on Wednesday, Jan. 20 and Trump will no longer be president by the time the order is set to go into effect.

Dominion Voting Systems on Monday sent a cease and desist letter to My Pillow CEO Mike Lindell over his spread of misinformation related to the 2020 election.

Why it matters: Trump and several of his allies have pushed false conspiracy theories about the company, leading Dominion to take legal action. It's suing pro-Trump lawyer Sidney Powell for defamation and $1.3 billion in damages, and a Dominion employee has sued Trump himself, OANN and Newsmax.
