It was pictured by the space agency's Perseverance rover that's been on the look out for signs of alien life.
"Gandalf's hat or a pot helmet?" one person remarked on Facebook.
"The Planet of the Sorting Hats has been found!" another said in reference to Harry Potter.
A third joked: "Martian buffalo's dung — nothing abnormal about it."
Other guesses included it looking like a "landed weather balloon" or "a relic from an ancient sea that was once on Mars".
The photo was named as Nasa's Image of the Week by public vote and has been a source of discussion since.
However, it's not some abandoned ancient alien accessory as some may think.
It's a rock that happens to be shaped like a hat, composed of spherules, tiny particles which are the result of volcanic activity or meteorite impacts.
The shape is likely to be due to processes such as wind erosion, volcanic activity, and mineral precipitation from ancient groundwater.
"This rock's target name is Horneflya and it's distinctive less because of its hat shape (which looks to me to be generally consistent with the pyramid shape we often see in of wind-eroded float blocks on the surface of Mars) and more because it's made almost entirely of spherules," David Agle, a spokesperson for the Perseverance team revealed to Space.com.

It's not the first time unexpected objects have been spotted on the Red Planet.
A strange cylinder-like piece previously fuelled speculation with people suggesting it could be an artifact of ancient civilisation on the Red Planet or a chunk of a crashed UFO.
However, it was later believed to be remnants of old spacecraft hardware.

Night Sky: Still time to catch the Perseid meteor shower
After midnight and looking up high in a north-easterly direction, you should still be able to catch a good number of meteors as the hours pass. Pictured is a bright Perseid fireball captured by Mary McIntyre. A fireball is a much larger and brighter spectacle, far outshining most regular meteors. If you intend to be up to watch the Perseids, there's also a great opportunity to catch an array of early morning planets. Situated above the east-northeast horizon on the morning of Wednesday August 20, there will be a thin crescent Moon sat near to Venus and Jupiter; Venus being the brighter of the two. On the following morning, Thursday August 21, the Moon will be positioned just above Mercury and with Venus and Jupiter in the vicinity it will make for a wonderful sight by sunrise. Space news and China have scored a significant goal as NASA's plans and schedules to return to the Moon continue to look uncertain. With the aim of placing two astronauts on the lunar surface by 2030, China has successfully completed tests of its 'Lanyue' (meaning 'embracing the Moon'), ascent vehicle, which will take its occupants down to the surface of the Moon. With NASA's budget cuts and logistical issues with their own space hardware, this might be the incentive needed for NASA and SpaceX to proactively respond. It was with sadness that news broke of the death of Commander Jim Lovell who has passed at the age of 97. We often pay tributes to people we've deemed as heroes and heroines and for me personally, Jim Lovell was one such man. While I didn't meet Jim Lovell, I did have the pleasure of meeting Fred Haise, now the last surviving member of the Apollo 13 crew. It was because of Lovell's calm, collected, and steadfast nature that Apollo 13 stood a chance of making it back to Earth when combined with the unified brain power of NASA's best at mission control. A true testimony to the man came when he remarked that only when he and his crew had returned safely to Earth, did he realize he didn't get to walk on the Moon. Sadly, for Lovell, he never did, but his actions onboard Apollo 13 spoke volumes about the man and his character. Lovell also said that when he put his thumb up to the window of the spacecraft and blotted out the Earth, he realized that behind his thumb were six billion people all striving to live there, remarking that one has to really think about one's own existence here in the universe. Finally, Barry 'Butch' Wilmore, the astronaut who spent a great deal longer in space than he intended onboard the International Space Station with fellow "stranded" colleague Suni Williams, has retired from NASA duties.

Scottish church window tribute to astronaut's inspiration
It commemorates the Linlithgow-born scientist Charles Wyville Thomson and his 1872 voyage that inspired space missions and astronauts of the 20th century. This voyage was named the Challenger Expedition, which laid the foundation for the field of oceanography over 150 years ago as the world's first exploration of the deep sea. It was a global expedition that sailed across the Atlantic, then to Australia and Hong Kong. They measured the ocean's depth, collected samples, and discovered all manner of new sea creatures, such as the pink New Zealand Lobster pictured in the bottom right of the St Michael's window. Another major discovery was the deepest part of the ocean, which they named the Challenger Deep, now known as part of the Mariana Trench. This mission is famous in the scientific community, and the parallels of travelling to the very edge of human knowledge made Challenger the perfect name for Nasa's latest space shuttle in 1982. One astronaut who flew on this shuttle was Kathy Sullivan, but her connection to this name was not limited to this flight to space. Kathy Sullivan in 1984. (Image: Getty Images) Before she was an astronaut, Sullivan was a student of oceanography in California, and was inspired by the Linlithgow-born lead scientist Wyville Thomson during her studies. 'Charles Wyville Thomson and the Challenger expedition founded the field of oceanography as a study, shifting what had been myth and speculation into a scientifically rigorous endeavour," she said. "But it means an awful lot to me because that's the field that I ended up finding my direction, finding my career, and finding a lifetime's worth of satisfaction. So I am forever grateful to Wyville Thomson and the Challenger expedition.' Read more: To later fly on the Challenger Shuttle to space was a great coincidence for her. She was also the first woman to both travel to space and the deepest part of the ocean, when she dived down to the Challenger Deep in 2020. Sullivan's trip to Scotland was an invitation from Alan Miller, a church member of St Michael's, who sought to reunite this piece of history with the space industry that carried on its namesake.

'I've never been to Linlithgow before, I've been to Scotland a few other times, but not to this village and not to this church to see that great east window and get more deeply into the story of Thomson and the vessel and the expedition," Sullivan said. "It's really been a fun coming-full-circle for my own career arc to get to be here.' She was also joined on the trip by Lance Bush, a former Nasa engineer, and CEO of the Challenger Centre in Washington DC, created after the shuttle exploded in 1986. 'The Challenger Centre was created by the families of the legendary crew of space shuttle Challenger 51-L, who were tragically lost," Bush said. "Over the almost four decades since it was created, Challenger Centre has inspired and engaged over 6.5 million students, with its network of centres across the US and also in several other countries.' Kathy speaks to the church. (Image: Graham Black) Bush connected with the Challenger window on a similar level to Sullivan. 'As a space enthusiast, it all comes together for me with the representation of the cosmos at the top of the window," he said. "This window provides such a unique perspective not often seen in church stained glass … I am in awe of all the generations of explorers that came before us, and realize the necessity for us as a society to continue that spirit.' The Challenger window as a whole is a representation of creation, complete with the bottom of the oceans, angels, and the stars in outer space. As Scotland returns to the business of expedition with the newly-announced Shetland satellite launchsite, the celebration of delving into the unknown and pushing the limits of human knowledge is as poignant and meaningful as ever.

Researchers discover the immune system's ‘fountain of youth' - but it has a cost
Researchers have discovered the 'fountain of youth' for cells - but it comes with a big cost. Some people over 60 years old were found to have immune systems that appear to much younger in wear-and-tear, Mayo Clinic researchers announced Thursday. The immune system is what protects us from getting sick and promotes healing. With age, the immune system's ability to protect the body from infection and disease can wane. Young immune systems are constantly exposed to new bacteria and viruses, and previous research has shown that infant immune systems beat those of adults at fighting off the invaders. Researchers now say some have immune systems that don't match their age. "We observed that these patients have very young immune systems despite being in their 60s and 70s,' Dr. Cornelia Weyand, a Mayo Clinic rheumatologist and clinician-scientist, said in a statement. 'But the price they pay for that is autoimmunity.' Autoimmunity is what happens when the immune system mistakenly attacks healthy tissues and organs. There are more than 100 known autoimmune diseases, according to the Cleveland Clinic, including lupus, multiple sclerosis, psoriasis, celiac disease and Hashimoto's thyroiditis. Women are at a higher risk than men, thanks to genetic and hormonal differences, according to Stanford Medicine. Doctors discovered this anomaly in more than 100 older patients who went to the Minnesota clinic to receive treatment for a rare autoimmune disease known as giant cell arteritis. Giant cell arteritis is an inflammation of the lining of your arteries that can affect the arteries in your head, the clinic explained. Untreated, it can lead to blindness, an aortic aneurysm, and, less commonly, stroke. It frequently causes headaches, jaw pain and vision problems. What causes the disorder remains unknown. Studying the diseased tissue of these patients, the researchers found they had specialized cells in their immune system known as 'stem-like T cells.' The cells behave like young stem cells, which are critical for repairing and maintaining a healthy immune system. But, in this case, they were spreading the autoimmune disease. Going forward, the scientists hope to learn more about this link and what they observed from the patients. "Contrary to what one may think, there are benefits to having an immune system that ages in tandem with the body," Dr. Jörg Goronzy, a Mayo Clinic researcher on aging, said. "We need to consider the price to pay for immune youthfulness. That price can be autoimmune disease."
