A curious discovery has captured the attention of both scientists and space enthusiasts. On Mars 's remote slope of Jezero Crater, NASA 's Perseverance rover sent back an image of a rock that resembled a human skull. About the size of a basketball, the rock-like structure is completely different from its dusty surroundings.For some people, it may seem like a cosmic coincidence, but for others, it is another reminder of the Red Planet's mystery and the possibility of life outside Earth.The Perseverance rover is a car-sized robotic spacecraft dispatched by NASA to explore the Jezero Crater on Mars as a key part of the Mars 2020 mission.According to Margaret Deahn, a Ph.D. student at Purdue University and a member of the NASA team, Skull Hill is most likely what's known as a 'float rock.' This means it didn't originate where it currently sits but was transported there by natural forces, likely from an impact crater or volcanic activity.'It could have come from a volcanic outcrop or a distant impact, carried over by ancient Martian winds or water flows,' Deahn explained. Scientists also estimate that as much as 30% of the surface rocks in Jezero Crater may have been displaced over millions of years.Some even suggest that it could be a meteorite, as Mars' thin atmosphere a lot of times fails to burn up the incoming space debris, and NASA's Curiosity rover had found several iron-nickel meteorites in Gale Crater.But in this case, after a closer inspection, Perseverance's SuperCam, which is a laser-powered chemical analyzer, revealed that Skull Hill's composition didn't match that of a typical meteorite.It also suggested that the object is an igneous rock formed from volcanic magma, and the presence of minerals like olivine and pyroxene, which are considered common in volcanic rocks, supports this theory.The pitted and angular surface of the Skull, along with its dark tone, makes it even more interesting. The pits are likely the result of wind erosion or the loss of small rock fragments. Rocks like Skull Hill are time capsules, offering critical clues about the planet's geological history and helping in understanding Mars' past.'Every rock we encounter on Mars is like a page in the planet's unfinished autobiography,' said Dr. Melissa Rice, a planetary geologist at Western Washington University. 'And Skull Hill? It's one of those chapters that makes you stop and think.'The question of whether Mars was ever home to life remains one of the most curious mysteries, and the search continues, with the hope that one day, the Red Planet will reveal its secrets.

Dickson Fjord's 650-foot mega-tsunami: How a giant wave sent shockwaves worldwide

What's TOI-6894b that just showed up around a dwarf star only 2.5 times its size; here's why that's weird
Astronomers have made a discovery that challenges long-standing beliefs about how planets form. A gas giant planet , roughly the size of Saturn, has been found orbiting an unusually small red dwarf star . This rare pairing defies current models, which say small stars don't have enough material in their surrounding disks to form such large planets. Named TOI-6894b, the planet was found about 241 light-years from Earth in the constellation Leo. TOI-6894b is about 1.07 times the diameter of Saturn but has just over half its mass. This makes the planet very low in density, similar to that of a beach ball. Despite its large size, the planet orbits extremely close to its host star, completing a full revolution in just under three Earth days.

In terms of physical size, the star is just 2.5 times wider than the planet itself, a remarkable size ratio rarely seen in planetary systems. Live Events Why This Is a Big Deal The formation of such a large planet around such a small star has puzzled astronomers. According to the well-accepted 'core accretion' model, large planets are thought to grow from small rocky cores that gradually gather gas from the star's surrounding protoplanetary disk. But small, dim stars like red dwarfs are believed to have disks too thin and short-lived to form massive planets before the gas disappears. Dr. Teruyuki Hirano, the lead researcher from the Graduate University for Advanced Studies in Japan, noted that this planetary system 'is completely inconsistent with what we thought we knew.' He said the discovery 'forces us to question our assumptions about planet formation .' Detected by TESS, Confirmed by Ground Telescopes The planet was first flagged by NASA 's Transiting Exoplanet Survey Satellite (TESS), which detects periodic dips in starlight caused by planets passing in front of their stars. Follow-up observations using the European Southern Observatory's Very Large Telescope (VLT) confirmed the planet's mass and orbit. Also Read: Rare superorganism 'wormnadoes' caught on camera for the first time; what is it exactly? More data will be needed to determine how TOI-6894b formed. Future observations by the James Webb Space Telescope could reveal more about its atmosphere and structure, including how much of it is made up of hydrogen and helium and whether it has a large core. Red dwarfs are the most common type of star in the Milky Way, making up about 75% of the stellar population. They're also seen as good candidates for hosting habitable planets due to their long lifespans. Discoveries like TOI-6894b suggest there's still much to learn about the diversity of planetary systems these stars may host. Though this is not the first time a massive planet has been found orbiting a small star, it is one of the most extreme examples yet.

Dickson Fjord's 650-foot mega-tsunami: How a giant wave sent shockwaves worldwide
In September 2023, Greenland's Dickson Fjord experienced a colossal landslide that triggered a 650-foot mega-tsunami, causing the Earth to pulse with rhythmic seismic signals every 90 seconds for nine days. New research using next-generation satellite technology and machine learning has revealed how these waves, called seiches, sloshed back and forth in the fjord, creating global seismic vibrations. The event highlights the hidden impacts of climate change in remote Arctic regions and marks a breakthrough in Earth monitoring technology. Tired of too many ads?
