The Daily Show has launched a new segment, "A Series of Gunfortunate Events," to help viewers keep track of all the completely whack gun-related incidents taking place around the country.

Thursday night's edition included mentions of the Parkland teacher who left his loaded gun in a public restroom, where it was found by a man who then fired it, as well as a 23-year-old with a concealed carry permit who shot himself while grocery shopping. Trevor Noah saved the best for last, though, with the story of a police officer at a children's learning center.

The officer — who didn't lose his job — said a third grade student was able to grab his gun and fire it; the bullet went into the ground, and no one was hurt in the debacle. "A third-grader grabbed a police officer's gun, unholstered it, and fired it before the cop could stop him?" Noah said. "That cop needs to be disciplined and that child needs to be promoted."

The observable limits of the solar system just stretched even further.

The International Astronomical Union's Minor Planet Center on Monday announced the discovery of a dwarf planet, 2018 VG18, located 120 astronomical units from the sun, reports CNN. It's the most distant object ever observed in the solar system so far, beating out Eris, the dwarf planet located 96 astronomical units away from the sun that previously held that distinction. One astronomical unit translates into 93 million miles, i.e. the distance between the Earth and the sun, and Pluto is located at 34 astronomical units.

The dwarf planet, which scientists are appropriately nicknaming "Farout," is described as round and pinkish, with a diameter of about 311 miles. Researchers believe it may have an ice-rich body based on the color.

This discovery came as part of a team of astronomers' search for distant objects in the solar system, including the possibility of a ninth planet, per Carnegie Science. They say that it will "take a few years" to determine the orbit of this dwarf planet, but they believe it likely takes it more than 1,000 years to take a single trip around the sun. Brendan Morrow

New York Gov. Andrew Cuomo (D) has an ambitious to-do list for 2019, and legalizing recreational marijuana is right at the top.

In a Monday speech revealing his plans for the first 100 days of his new term, Cuomo said he'd push to "legalize the adult use of recreational marijuana." Cuomo had been resistant to legalization as recently as last year, calling weed a "gateway drug," but his new take would put New York in line with 10 other states that have legalized and taxed marijuana, The New York Times notes.

Cuomo acknowledged Monday his view had changed, citing a report compiled by New York's health department in July that showed the "positive effects" of legalization outweigh the negatives. He said current criminalization of marijuana use has "for too long targeted the African American and minority communities," and added that the $1.7 billion in potential marijuana sales could bring in much-needed tax dollars. That revenue could fund education or other public works, or, as some suggest, much-needed repairs to New York City's subway system.

Cuomo's push to change marijuana legislation comes after a Quinnipiac University poll in May showed 63 percent of New Yorkers backed the legalization of recreational marijuana. Neighboring New Jersey has indicated it could legalize weed by January 2019, and Massachusetts took the plunge in 2016.

Also in Monday's speech, Cuomo pledged to make New York carbon neutral by 2040, per CBS News. Kathryn Krawczyk

Two of former National Security Adviser Michael Flynn's former associates have been hit with indictments.

Bijan Kian and Ekim Alptekin were charged Monday with counts of conspiracy and illegally acting as agents of a foreign government, reports CNN. The Justice Department says they were both involved in a "conspiracy to covertly influence U.S. politicians and public opinion" against Fethullah Gulen, a Turkish cleric living in Pennsylvania whose extradition has been requested by Turkish President Recep Tayyip Erdogan. The two men sought to delegitimize Gulen with the goal of getting him extradited, all while hiding the fact that they were being directed by the government of Turkey, the DOJ says. Flynn's lobbying firm, Flynn Intel Group, was used as part of this effort, NBC News reports.

Additionally, Alptekin is charged with four counts of making false statements to the FBI. Documents that have been unsealed as part of this case show that Flynn was working to promote Turkey's agenda even as he was angling for a role in President Trump's administration, per The Washington Post. Flynn is scheduled to be sentenced for lying to the FBI on Tuesday and has previously admitted to lying about participating in lobbying for Turkey, per Politico. Brendan Morrow

Sen. Lamar Alexander (R-Tenn.) is about to start his last two years in the Senate.

The 78-year-old senator announced Monday he would not run for re-election in 2020, seemingly hinting at his retirement. A longtime politician, Alexander served as Tennessee's governor from 1979 to 1987 and as the Secretary of Education before heading to the Senate in 2003.

Alexander thanked "the people of Tennessee" for "electing me to serve more combined years as governor and senator than anyone else from our state," he said in his Monday statement. "But now it is time for someone else to have that privilege," Alexander continued.

Fellow Tennessee Republican Sen. Bob Corker didn't run for re-election in 2018, and Rep. Marsha Blackburn (R-Tenn.) won his seat. Corker quickly responded to Alexander's news with a statement of his own. Kathryn Krawczyk

Working in big cheese is really starting to stink.

American cheese exports are down drastically this year, largely thanks to Mexico and China issuing dairy tariffs in response to President Trump's trade war. Now, there's a 1.4 billion pound pileup in cold storage facilities across the country as cheddar prices continue to tank, The Wall Street Journal reports.

U.S. cheesemakers are currently sitting on the largest stockpile in recorded history. But it's not because Americans aren't tolerating the lactose, seeing as they "ate a record 37 pounds of natural cheese per capita last year," the Journal says. It's because cheesemakers increased production to meet that higher demand, only to see it sliced amid Trump's trade war. Mexico's intake of American cheese went down by more than 10 percent in the past year after issuing tariffs on cheese and whey, while China's imports fell by 63 percent, per the U.S. Dairy Export Council.

Americans are also largely rejecting traditional American slices in favor of foreign varieties like Gouda and Havarti. Mexican and Chinese buyers would've typically gobbled up the processed slices, but in the face of the trade conflict, that cheese is simply aging away in cold storage. Cheddar prices are down 24 percent this year from 2014 prices, leading producers to worry tariffs "could eat into profits," the Journal writes. Milk prices are also down 40 percent from 2014, and more than 600 dairy farms in Wisconsin have closed this year.

Instagram, not Facebook, may be Russia's most effective tool for spreading propaganda.

A new report prepared for the Senate Intelligence Committee shows that posts from the Russian Internet Research Agency, a troll farm, received 187 million interactions on Instagram from 2015 through 2018, and only 77 million interactions on Facebook and 73 million on Twitter, reports Bloomberg.

This suggests Instagram has been a much more significant factor in Russia's attempt to manipulate American politics through social media than previously thought, and the report notes that this is "something that Facebook executives appear to have avoided mentioning in congressional testimony." The researchers also say that Instagram could be "more ideal" for spreading propaganda through memes than other platforms and that it is "likely to be a key battleground on an ongoing basis."

Additionally, the report says that not only did Russian trolls seek to promote President Trump's campaign and damage Hillary Clinton's, but the "most prolific IRA efforts on Facebook and Instagram specifically targeted black American communities," The New York Times reports. While the Russian troll farm targeted some other specific groups with a handful of accounts and pages, "the black community was targeted extensively with dozens," researchers conclude. On Facebook, for instance, among 81 Facebook pages the IRA created, 30 targeted black Americans. Efforts to encourage people to skip voting or vote against Clinton targeted both black Americans and supporters of Clinton's primary opponent, Sen. Bernie Sanders (I-Vt.).
