☆ Fossil-fuel companies have more people at the UN's climate summit than the 10 countries most affected by climate change do combined

Fossil-fuel interests are fighting for natural gas at the United Nations' COP27 climate summit. But natural gas is mostly methane — a greenhouse gas 80 times more potent than carbon dioxide — and it leaks. One-third of the fossil fuel lobbyists Global Witness identified are registered as part of national delegations, according to Dominic Kavakeb, a spokesperson for Global Witness. Fossil fuel influence threatens to undermine progress on one of the most powerful, immediate climate solutions: ending human methane emissions. While methane's consequences are severe, the good news is that countries and industries can quickly slow climate change by cutting methane emissions.

SpaceX CEO Elon Musk, left, speaks to NASA astronaut Bob Behnken at the launch tower of Kennedy Space Center's LC-39A complex on Mar. CNBC's Investing in Space newsletter offers a view into the business of space exploration and privatization, delivered straight to your inbox. Indeed, early in its history, SpaceX won a crucial contract from NASA to deliver cargo to the International Space Station — before it even made it to orbit. Put another way, SpaceX is currently the sole path for NASA astronauts to get to and from orbit. NASA," Nelson said.

☆ 'Planet killer' asteroid hidden by the sun may threaten Earth in a few thousand years

Astronomers discovered a "planet killer" asteroid that may pose a threat to Earth in future millennia. That makes it a "planet killer," Scott S. Sheppard, an astronomer at the Carnegie Institution for Science, said in a press release announcing the discovery on Monday. But there could be other planet killer asteroids lurking unseen in the blind spot where 2022 AP7 was discovered: within the orbits of Earth and Venus, between us and the sun. That makes it very difficult to spot asteroids located between Earth and the sun. "There are likely only a few [near-Earth asteroids] with similar sizes left to find," Sheppard said in the release.

NASA's InSight lander felt a powerful Mars quake. Then an orbiter took a picture of the meteor impact that caused it. The impact kicked up boulders of water ice, which will be crucial for future astronaut missions to Mars. "It was immediately clear that this is the biggest new crater we've ever seen," Ingrid Daubar, InSight impact science lead, said in a press briefing.

NASA's InSight lander has detected Mars quakes that mostly come from one region: Cerberus Fossae. But now, using a seismometer on NASA's InSight lander, scientists have discovered the first evidence of molten lava deep below the Martian surface. A series of Mars quakes clued the scientists in to the potential lava hotspot. The biggest Mars quakes point to an underground chamber of magmaInSight has detected more than 1,300 Mars quakes since landing on the red planet in 2018. To get the global picture of Mars quakes and volcanic activity, NASA would need to send more seismometers to the red planet.

☆ The asteroid NASA is about to strike poses no threat to Earth, but 60% of city-killer rocks fly under the radar

The Double Asteroid Redirection Test (DART) is aiming for an asteroid called Dimorphos, which is orbiting a giant asteroid called Didymos. To date, scientists have only identified 40% of city-killer asteroids orbiting near Earth, NASA estimates. Mainzer has been working on a space telescope called Near-Earth Object (NEO) Surveyor, which is designed to fulfill that goal. The asteroid-spying telescope got a huge budgetary boost in 2022An artist's concept of the NEO Surveyor space telescope. If the DART impact goes according to plan on Monday, NASA will be better equipped to divert any Earth-bound asteroid NEO Surveyor might discover.

NASA shared the sound of a meteor falling to Mars, with photos of the impact craters, on Monday. The dwindling InSight lander has captured the acoustic and seismic noise of four meteor impacts.

☆ Saturn's gravitational pull shredded an ancient moon, creating its iconic rings and unusual tilt, new research suggests

New models suggest Saturn's gravity shredded a moon, Chrysalis, about 160 million years ago. The ancient moon could explain two long-standing mysteries: Saturn's iconic rings and dramatic tilt. Cassini captured five of Saturn's moons in a single frame, on July 29, 2011. Saturn's rings display their subtle colors in this view captured by NASA's Cassini spacecraft, on August 22, 2009. NASA/JPL-Caltech/Space Science InstitutePlanetary scientists have long suspected Saturn's tilt may have come from gravitational interactions with Neptune.

A toaster-sized device called MOXIE is tucked inside NASA's Perseverance rover, which landed on Mars in 2021. NASA's Perseverance rover descends onto Mars, on February 18, 2021. The oxygen atoms then combine with each other to produce oxygen gas. MOXIE splits carbon dioxide into carbon monoxide and oxygen atoms, before the single oxygen atoms combine to make breathable oxygen. Researchers imagine a jumbo version of MOXIE, approximately 100 times larger, could produce oxygen at the same rate as several hundred trees.

Experts have estimated that aviation is responsible for nearly 2% of global greenhouse-gas emissions and 2.5% of carbon-dioxide emissions. Some aviation giants, like United, are signing purchase agreements to buy electric aircraft. Today he serves as CEO and chairman of the company, which aims to be a pioneer in electric aircraft. In 2000 he founded Aviation Technology Group, which developed the ATG Javelin very light jet before ceasing operations in 2007. He is also a founding member of the Nordic Network for Electric Aviation.

☆ The head of Amazon's quantum computing product explains its master plan as it signs key partnerships to establish a foothold in the next big thing

Amazon was relatively quiet about quantum computing until it announced Amazon Braket in 2019. Amazon Web Services has been ramping up its quantum computing partnerships in the past few months. Along with that, AWS will offer cloud software from Quantum Computing Inc., which helps companies solve business problems using quantum computing, and it recently partnered with BMW to launch a quantum computing challenge to crowdsource automative projects in the field. That silence ended in 2019 when AWS announced its quantum computing service, Amazon Braket. In quantum computing, there's a lot of "noise" that gets in the way of solving problems, so this approach aims to reduce errors.

Enceladus, unul dintre sateliții lui Saturn, ar putea avea curenți oceanici similari cu cei de pe PământPotrivit unei noi analize a stratului de gheață care acoperă oceanele globale ale lui Enceladus, curenți foarte similari cu cei de Pământ par să curgă pe acolo. Asta ar însemna că oceanele satelitului lui Saturn ar putea să nu fie omogene până la urmă. Combinația de apă lichidă și fisuri în gheață i-a ajutat pe oamenii de știință să înțeleagă modul în care Enceladus funcționează. Mai știm și că apele de pe Enceladus sunt sărate. De asemenea, mai știm și că, pe Terra, curenții oceanici joacă un rol în distribuirea de nutrienți.

Астрономы обнаружили возможного двойника таинственной девятой планеты Солнечной системы, находящегося в 336 световых лет от Земли. В 2006 году выяснили, что Плутон не является полноценной планетой, а на самом деле это первый открытый объект пояса Койпера. Со временем выясняли, что в некоторых орбитах объектов пояса Койпера наблюдаются закономерности, которые только воздействием Нептуна объяснить не удается. Одно из объяснений природы Девятой планеты может состоять в том, что планеты не существует. В начале декабря 2020 года стало известно о том, что астрономы обнаружили возможного двойника таинственной девятой планеты Солнечной системы.
