The Odysseus lander launched atop a SpaceX rocket on a journey to the lunar surface — aiming for the first touchdown of a US-made spacecraft on the moon in decades. The Odysseus lunar lander, nicknamed “Odie” or IM-1, has embarked on a historic journey to the lunar surface — aiming to make the first touchdown of a US-made spacecraft on the moon in five decades. The launch follows closely on the heels of a separate US lunar landing mission that failed in January. NASA has ramped up the development of robotic spacecraft via private partners to evaluate the lunar environment...

I got a lot of questions last week about an article in Quanta Magazine about Dark Dimensions. it's about an idea motivated by string theory that combines large extra dimensions with dark matter.

[Video] A camera at the Mauna Kea Observatory in Hawaii has captured an object as it burned up on re-entering Earth's atmosphere on 8 February. The Subaru-Asahi Star Camera, owned by the National Astronomical Observatory of Japan, recorded a time-lapse of the fireball blazing across the night sky, followed by smaller glowing streaks.

An enormous sunspot, which can be seen from the surface of Mars, is turning towards Earth as scientists warn of a possible ‘grid destroying’ solar flare. Sunspot group AR3576, which measures 124,274 miles across the sun’s surface, contains four dark cores larger than planet Earth, according to Spaceweather. The group was so big it could be seen from Mars by NASA’s Perseverance Rover, However, scientists are now warning the sunspot is turning towards Earth. While the sunspot is only forecast to cause a G1-class geomagnetic storm, it is still close to Earth. However, the forecast is based on a “coin...

The sunspot group is now facing Earth. The sunspot group is more than 15 times the diameter of Earth. (Image credit: NASA/SDO and the AIA, EVE, and HMI science teams) A sunspot so large it was seen from the surface of Mars is now facing Earth. The gargantuan sunspot group AR3576 from end to end stretches for more than 124,274 miles (200,000 kilometers) and contains at least four dark cores each larger than Earth, according to Spaceweather.com. It was imaged by NASA's Perseverance Rover from the surface of Mars just last week. The sunspot is so big it can be...

(Jacob Long/Lawrence Livermore National Laboratory) In December 2022, scientists at the US National Ignition Facility announced a historic milestone: for the first time, their laser-powered fusion reaction had 'broken even', producing more energy than it consumed. But advances as big as this need to be rigorously checked – and that can take some time. Importantly, a series of papers detailing the experimental design, technological advancements, and results of the initial breakthrough reaction have just passed peer review, meaning researchers not involved in the work have vetted the methods and findings in order to check the sums. "This achievement is the...

Could a recently discovered "super-Earth" have the potential temperature and conditions to sustain life? The new exoplanet is situated "fairly close to us" -- only 137 light-years away -- and orbits within a "habitable zone," according to NASA. Astronomers say the planet, dubbed TOI-715 b, is about one and a half times the width of Earth and orbits a small, reddish star. The same system also might harbor a second, Earth-sized planet, which, if confirmed, "would become the smallest habitable-zone planet discovered by TESS [the Transiting Exoplanet Survey Satellite] so far," NASA said in a Jan. 31 press release.

Researchers at Germany’s TU Dortmund University report that they have developed an ultra-robust time crystal. Their study, published in Nature Physics, offers new insights into the potential applications and the physics governing time crystals, and offers a new method for keeping them stable. Time crystals represent a new phase of matter, first theorized in 2012 by Nobel laureate Frank Wilczek. Unlike traditional crystals, which exhibit repeating patterns in space, time crystals display patterns that repeat in time. This means their atomic structures undergo periodic motion even without external energy, defying the traditional laws of thermodynamics that govern equilibrium in most...

Professor Holland:"According to the (ret) head of a pan European radio telescope project, an extraterrestrial signal was detected 11 light years away in 2019. He told me, we are in regular contact with the aliens. Is this true? How would we speak in real time to an ET, 11 light yers away? maybe with Quantum Tunneling Communication. Some of this story makes sense, other bits are pure science fiction. Is this the BIG reveal we have all bee waiting for, or is it just bollocks? you choose. It's an interesting quest."

It turns out space helmets serve a dual purpose - to keep air in and stink out. Just like Earth, the universe emits various smells from every corner of the never-ending universe, often of which are generally unpleasant, Space.com reported, citing numerous space expeditions over the decades. Although it is impossible to take a whiff of the cosmos without facing certain death, astronauts have long described strong odors clinging to their space suits after they return to their air-locked chambers. Metallic, burnt meat Those aboard the Apollo moon landings described the scent as gunpowder-like, while others who traversed the International...

Early on Jan. 19, several pilots reported "multiple lights sometimes in a triangle formation(opens in a new tab)" high above the Canadian Prairies. The 13-minute clip was culled from 2.5 hours of raw audio downloaded from two feeds at LiveATC.net(opens in a new tab), a website that streams and archives air traffic control radio. Edited for length, the original conversations between pilots and air traffic controllers took place from approximately 4:20 a.m. to 6 a.m. CST. At least four aircraft reported seeing the lights that morning, including Flair and Morningstar jets, and two Air Canada flights. They estimated the lights...

In a groundbreaking discovery, scientists have unraveled an anti-gravity mystery that seemingly defied the norms of classical physics, potentially paving the way for revolutionary advancements in magnetic levitation technology. The breakthrough centers on a unique form of magnetic levitation, first demonstrated in 2021 by Turkish scientist Hamdi Ucar, an electronics engineer from Göksal Aeronautics in Turkey. Typically, the setup becomes unstable when you try to balance two repelling magnets to counter gravity. However, in a study featured in the journal Symmetry, Ucar revealed that when positioned close to another swiftly rotating magnet, a magnet can both spin and levitate in...

Explanation: Epsilon Tauri lies 146 light-years away. A K-type red giant star, epsilon Tau is cooler than the Sun, but with about 13 times the solar radius it shines with nearly 100 times the solar luminosity. A member of the Hyades open star cluster the giant star is known by the proper name Ain, and along with brighter giant star Aldebaran, forms the eyes of Taurus the Bull. Surrounded by dusty, dark clouds in Taurus, epsilon Tau is also known to have a planet. Discovered by radial velocity measurements in 2006, epsilon Tauri b is a gas giant planet larger...

The eighth-ever prediction of an asteroid impact has delivered some bounty! The discoverer with the little meteorite in hand. Image Credit: Cevin Dettlaff Earlier this week, for only the eighth time ever, an asteroid that actually came with a rare 95-minute warning exploded in the sky over Germany and the hunt began for any potential pieces of meteorite that survived burning up in the atmosphere and fell to Earth. Now, researchers think they have found them. Fragments of asteroid 2024 BX1 about the size of a walnut have been recovered by researchers from the Museum für Naturkunde Berlin and colleagues,...

Size comparison of Venus and Earth. Credit: NASA/JPL/Magellan Venus is only slightly smaller than the Earth, and so has enjoyed billions of years of a warm heart. But for this planet, sometimes called Earth's sister, that heat has betrayed it. That planet is now wrapped in suffocating layers of a poisonous atmosphere made of carbon dioxide and sulfuric acid. The pressures on the surface reach almost 100 times the air pressure at Earth's sea level. The average temperatures are more than 700°F, more than hot enough to melt lead, while the deepest valleys see records of more than 900°. If...

The search for exomoons orbiting planets outside our solar system has sparked a significant debate within the astronomical community, involving a pair of contrasting studies that presented divergent viewpoints on the existence of exomoons Kepler-1625b-i and Kepler-1708b-i. Much like Schrödinger’s oddball cat that is both dead and alive inside a box, we won’t really know until someone goes and looks. But in a new paper recently uploaded to the arXiv preprint server, a team of astronomers led by David Kipping from Columbia University takes issue with the drama surrounding the ongoing exomoon search. A DISCOVERY GETS DASHED In 2017, Kipping,...

Image of Uranus from Webb It seems crazy that Uranus was discovered in 1781 yet here we are, in 2024 and we have only sent one spacecraft to explore Uranus. Voyager 2 is the only spacecraft to have given us close-up images of Uranus (and Neptune) but since their visit in 1986, we have not returned. There have of course been great images from the Hubble Space Telescope and from the James Webb Space Telescope but we still have lots to learn about them. The discovery of Uranus was accidental! British astronomer William Herschel was surveying stars that were too...

An international team of chemists has set a new world record for tying the world’s smallest knot, which they say consists of only 54 atoms. Remarkably, researchers involved with the achievement say it happened by accident, and are unable to account for how it occurred. Chemists Zhiwen Li, Jingjing Zhang, Gao Li with the Chinese Academy of Sciences’ Dalian Institute of Chemical Physics, and research colleague Richard J. Puddephatt with the University of Western Ontario, Canada, were attempting an entirely different process in the lab when the record breaking discovery was made. Their achievement is described in a study that...
