It's Official: Scientists Confirmed What's Inside Our Moon
Well, the verdict is in. The Moon is not made of green cheese after all. A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, a solid ball with a density similar to that of iron. This, researchers hope, will help settle a long debate about whether the Moon's inner heart is solid or molten, and lead to a more accurate understanding of the Moon's history – and, by extension, that of the Solar System. "Our results," wrote a team led by astronomer Arthur Briaud of the French National Centre for Scientific Research in France, "question the evolution of the Moon magnetic field thanks to its demonstration of the existence of the inner core and support a global mantle overturn scenario that brings substantial insights on the timeline of the lunar bombardment in the first billion years of the Solar System." Watch the video below for a summary on what they found: Probing the interior composition of objects in the Solar System is most effectively accomplished through seismic data. The way acoustic waves generated by quakes move through and reflect from material inside a planet or moon can help scientists create a detailed map of the object's interior. We happen to have lunar seismic data collected by the Apollo mission, but its resolution is too low to accurately determine the inner core's state. We know there is a fluid outer core, but what it encompasses remains under debate. Models of a solid inner core and an entirely fluid core work equally well with the Apollo data. To figure it out once and for all, Briaud and his colleagues collected data from space missions and lunar laser-ranging experiments to compile a profile of various lunar characteristics. These include the degree of its deformation by its gravitational interaction with Earth, the variation in its distance from Earth, and its density. Next, they conducted modeling with various core types to find which matched most closely with the observational data. They made several interesting findings. Firstly, the models that most closely resembled what we know about the Moon describe active overturn deep inside the lunar mantle. This means that denser material inside the Moon falls towards the center, and less dense material rises upwards. This activity has long been proposed as a way of explaining the presence of certain elements in volcanic regions of the Moon. The team's research adds another point in the "for" tally of evidence. And they found that the lunar core is very similar to that of Earth – with an outer fluid layer and a solid inner core. According to their modeling, the outer core has a radius of about 362 kilometers (225 miles), and the inner core has a radius of about 258 kilometers (160 miles). That's about 15 percent of the entire radius of the Moon. The inner core, the team found, also has a density of about 7,822 kilograms per cubic meter. That's very close to the density of iron. Curiously, in 2011 a team led by NASA Marshall planetary scientist Renee Weber found a similar result using what were then state-of-the-art seismological techniques on Apollo data to study the lunar core. They found evidence of a solid inner core with a radius of about 240 kilometers, and a density of about 8,000 kilograms per cubic meter. Their results, Briaud and his team say, are confirmation of those earlier findings, and constitute a pretty strong case for an Earth-like lunar core. And this has some interesting implications for the Moon's evolution. We know that not long after it formed, the Moon had a powerful magnetic field, which started to decline about 3.2 billion years ago. Such a magnetic field is generated by motion and convection in the core, so what the lunar core is made of is deeply relevant to how and why the magnetic field disappeared. Given humanity's hope to return to the Moon in relatively short order, perhaps we won't have long to wait for seismic verification of these findings. The research has been published in Nature. A version of this article was first published in May 2023.

Scientists trying to grow Devon tea plants in space
Scientists are using plants from Devon to test whether it is possible to grow tea in space. Seedlings cultivated near Ashburton have been planted in soils which are similar to those found on the Moon and Mars as part of a research project at the University of Kent. The team said the aim was to be able to ultimately grow food in space for people who are based on space stations and the Moon in the future. Jo Harper, who owns Dartmoor Estate Tea which provided the plants, said it was a "mind-blowing" idea. 'New age of space' Prof Nigel Mason, who specialises in molecular physics at the University of Kent, said this could contribute to research into whether food can be grown in added: "We're moving into a new age of space, where we no longer just want to explore, but we want to settle space, we want to put people onto space stations and build bases on the Moon."As soon as you consider that, one of the first things you want to know is, 'what will people eat?'"The fun part of the project is to to see whether we could grow things on the Moon, but a lot of the basic work is also about how crops and plants survive harsh environments and poor soils, and poor soils are a big problem with climate change." Researcher Anna-Marie Wirth, 22, said she thought it was "really cool" tea plants were being tested. "Tea is a huge part of British culture and cultures around the world," she will monitor how the plants develop over the course of 30 days, with temperature, humidity and lighting controlled to mimic conditions in have been grown in space before after a small food-growing trial by Italian and American scientists. Kathryn Harper, from the Dartmoor Estate Tea, said people needed the drink, "even in space"."If they're growing it themselves, then those on the International Space Station would have access to their daily brew, their daily cup of tea," she results of the experiment are expected in summer 2025.

Musk's meltdown era is here
Elon Musk is unraveling in real time. This week, SpaceX's Starship rocket exploded — again — during a ground test in Texas. That makes four failures in six months for the company's most ambitious project, the one NASA is relying on to carry astronauts back to the moon. But what's another fiery setback in MuskLand? Nothing much, if you listen to Musk's own X account. While the smoke clears on the launchpad, another crisis is burning: xAI, Musk's artificial intelligence venture, is reportedly on track to lose $13 billion in 2025. According to multiple reports, it's burning through $1 billion every month, and bringing in barely a half-billion total. Musk moved GPUs from Tesla to prop it up and is now pitching a $9 billion raise to investors. But that's not innovation — it's triage. And now, the political theater collapses too. After years of courting Donald Trump and MAGA-adjacent culture warriors, Musk has been frozen out by Trump himself, who reportedly isn't taking Musk's calls. No more backstage passes. No more power dinners. Just a guy with exploding rockets, a hemorrhaging AI startup, and a dying social media platform full of trolls yelling into the void. Once the architect of disruption and chainsaw-wielding White House Senior Adviser, it now feels like he's a brand built on fire and fumes. Musk promised moon landings, AI revolutions, and free speech utopia. What we got instead? A billionaire in free fall — and the receipts are everywhere.

Daily Horoscope for June 20, 2025
General Daily Insight for June 20, 2025 Retreating within our shells isn't shameful. The intuitive Moon initially slides into stability-seeking Taurus, so we'll hardly be in the mood to rush off first thing. Our energy levels may even take an additional hit when Mars makes a quincunx to foggy Neptune, casting a veil over our ambitions. Caffeine might be necessary for productivity! The Sun will make a major change at 10:36 pm EDT when it enters sensitive Cancer for its annual visit, encouraging us all to seek out comfort and security. Aries March 21 – April 19 Feeling your way forward is a perfectly valid approach. Leading with an open heart will be wise while the Sun settles down in your emotional 4th house for its yearly tour. This is a great time to inspect your internal foundations and make sure that you're stable and secure. If you need support, don't hesitate to ask your loved ones for a shoulder to cry on. A relative or roommate could prove especially comforting, so let yourself freely share your feelings. Taurus April 20 – May 20 Hitting the town and having fun is the name of your game today! The Sun is shimmying into your chatty 3rd house for the next thirty days, so there's no need to sequester yourself on the couch or keep your thoughts to yourself. No, it is time to go out and take part in your community by investigating whatever your pals are up to. You could discover some really exciting and interesting opportunities if you do. Approach your local vicinity with fresh eyes. Gemini May 21 – June 20 You can only fly by the seat of your pants for so long. The stars are encouraging you to focus on more grounded matters as the Sun marches into your 2nd House of Checks and Balances, acting as a firm reminder of your funds and what you do with them. If your resources feel limited or stagnant, then this cycle can drum up countless opportunities to increase your sense of abundance and security. Roll up your sleeves and get to it! Cancer June 21 – July 22 Step to the front of the line! It is your moment, according to the cosmic calendar, as the Sun arrives in your 1st House of Action, propelling you up to amazing heights. This is your birthday season for a reason, so put your heart and soul into whatever matters most to you right now. Even if you aren't blowing out any candles, you can still make a few wishes. Get clear about what you want, then go after it as fast as you can. Leo July 23 – August 22 Less is more for the time being. The energy is turning down a notch or two as the Sun enters your secluded 12th house for the next month — this may feel like an extended snooze fest. This time is not about initiations or new beginnings, but rather wrapping up loose ends and clearing away the clutter in your life. This process should create plenty of room for fresh opportunities when the Sun enters your sign in July. Until then, take it easy. Virgo August 23 – September 22 No person is an island. Even if you think of yourself as a rather isolated peninsula, you still need to forge connections and surround yourself with quality connections — especially as the Sun is moving into your 11th House of Group Associations. This is a wonderful thirty-day opportunity to meet new acquaintances who may prove very pivotal to your life down the line, while also enjoying the friendships you already have. Don't play the lone wolf! Explore the joy of being part of the pack. Libra September 23 – October 22 Put your heart and soul into your goals. You've got a special burst of energy pushing you up life's great ladder, thanks to the Sun entering your reputation zone for the next thirty days. This is the perfect time to chase after your ambitions and put in the required effort to get that much closer to them. Any effort you exert in this moment could yield immensely potent and even profitable results. This is no time for resting on your laurels! Scorpio October 23 – November 21 There is nothing to be gained by limiting yourself. In fact, you have everything to gain by looking beyond your usual limitations and boundaries as the Sun flies into your unrestrained 9th house. From going on a nature walk to booking an exotic vacation, the world really is full of endless opportunities to learn and grow! Go to the library and check out a book on something that's always fascinated you. Taste-test a new recipe with your loved ones. The experience alone will be valuable. Sagittarius November 22 – December 21 Keep your cards close to your chest. There is an undeniably air of secrecy and intensity settling around you as the Sun slips into your private 8th house. This cycle is all about extremes, so you may not be interested in spending time with anyone who doesn't bring something important or meaningful to the connection. You might prefer your own company over meaningless chatter. That's okay — it is within those quiet moments that you will make some important realizations. Take space for your epiphanies. Capricorn December 22 – January 19 It is okay to rely on other people. Capricorn is known for its tendency to be one of the most self-sufficient signs of the zodiac, but with the Sun arriving in your cooperation quadrant for its yearly visit, make an effort to focus on your most vital connections. That isn't to say you need to form expectations of other people, because unnecessary expectations risk breeding premature resentment. Merely give them the space to support you in the same way you'd want to assist them. Aquarius January 20 – February 18 Simplicity is more useful than ever. You've potentially had enough bells and whistles while the Sun danced through your playful 5th house. Now that it's entering your detailed 6th house, which is all about streamlining and improving your daily life. That may not sound very exciting at first glance, but the potential to feel so much better about yourself, both mentally and physically, is the reward on offer here. Don't leave such a wonderful blessing for someone else to pick up. Pisces February 19 – March 20 Step into the spotlight, Pisces. The Sun is making its annual visit to your 5th House of Music, which means it's your turn to let your natural talents flow as freely as possible. The emotional rewards should be wonderful! Whether you're belting it out at karaoke night or putting your art on display at a gallery, you can enjoy life the most when you stop dimming your own shine. This same sector rules fame, so your talents have an extra chance to carry you far.
