Explanation: Ever wonder what it would look like to crack open the Sun? The Egg Nebula, a dying Sun-like star, can unscramble this question. Pictured is a combination of several visible and infrared images of the nebula (also known as RAFGL 2688 or CRL 2688) taken with the Hubble Space Telescope. The star has shed its outer layers, and a bright, hot core (or "yolk") now illuminates the milky "egg white" shells of gas and dust surrounding the center. The central lobes and rings are structures of gas and dust recently ejected into space, with the dust being dense enough...

Aliens exist — they just haven’t visited Earth, a NASA veteran has claimed. Dr. Gentry Lee has worked at the US space agency since 1968, when he first got involved with the Viking mission to Mars. He has since spent more than half a century designing probes to land on distant planets — but argues Earth has not yet been visited by otherworldly beings. “There exists nothing today that says any alien or any alien machine has ever landed on the planet Earth,” he told the American Association for the Advancement of Science (AAAS) conference in Phoenix. “If you believe...

As nearly half of U.S. adults say they’re actively trying to drink less, the non-alcoholic aisle has become crowded with options that promise ritual without consequence. The problem is that many of them taste like cough syrup or some other kind of compromise. Wine, in particular, has historically struggled in this category. As a professional product tester, I can attest to my own disenchantment with non-alcoholic wine, to the point that I’ve covered it maybe once before. You can remove the alcohol, but can you preserve structure, aroma and the layered character that makes wine worth pouring in the first...

A software engineer in Spain, used an AI assistant to reverse engineer how a robot vacuum cleaner communicated with DJI cloud servers so he could control his vacuum using the joystick on his game controller and inadvertently took control of over 7000 remote vacuum cleaners which allowed him full control over devices in 24 countries, he had full access to the audio and video coming from the devices, he could control the movement of the devices and was able to produce a detailed map of where the devices were located. Fortunately, the individual reported the security flaw to the company...

Explanation: Look up this week and see a whole bunch of planets. Just after sunset, looking west (mostly), planets Mercury, Venus, Saturn, and Jupiter will all be visible to the unaided eye simultaneously. If you have a telescope, planets Uranus and Neptune can also be seen. In order up from the horizon, the lineup this week will be Venus (the brightest), Mercury, Saturn, Neptune, Uranus, and Jupiter (second brightest). It doesn't matter where on Earth you live because this early evening planet parade will be visible through clear skies all around the globe. The planets will appear to be nearly...

Around 2,500 years ago in Siberia, a young woman experienced a serious head injury, underwent surgery to reconstruct her jaw, and received a primitive prosthetic during the procedure, CT scans of the woman's mummified remains reveal...In 1994, archaeologists with the Russian Academy of Sciences excavated a small cemetery consisting of five low mounds on the Ukok Plateau. One mound held the undisturbed burial of a woman who was around 25 to 30 years old when she died. She was lying on a wooden cot and was wearing a wig. But because her burial lacked significant artifacts and only a part...

...Chlorophyll, the main photosynthetic pigment of plants, absorbs mainly blue and red wavelengths from the Sun and reflects green ones, and it is this reflected light that gives plants their leafy color. This fact puzzles some biologists because the sun transmits most of its energy in the green part of the visible spectrum...DasSarma thinks it is because chlorophyll appeared after another light-sensitive molecule called retinal was already present on early Earth. Retinal, today found in the plum-colored membrane of a photosynthetic microbe called halobacteria, absorbs green light and reflects back red and violet light, the combination of which appears purple.Primitive...

This revelation has made the Yunxian skulls from Hubei province the oldest evidence of our early human relatives, known as hominins, in East Asia, according to research published Wednesday (Feb. 18) in the journal Science Advances...H. erectus has long been considered the first human relative to leave Africa, with 1.78 million to 1.85 million-year-old fossils found at the Dmanisi site in Georgia being the earliest evidence of humans in Asia. But stone tools discovered at two sites in China dated to 2.1 million and 2.43 million years ago have complicated that picture, since they predate experts' theory of when H....

Explanation: Have you ever seen the Pleiades star cluster? Even if you have, you probably have never seen it as large and clear as this. Perhaps the most famous star cluster on the sky, the bright stars of the Pleiades can be seen with the unaided eye even from the depths of a light-polluted city. With a long exposure from a dark location, though, the dust cloud surrounding the Pleiades star cluster becomes very evident. The featured 18-hour exposure, taken from Bory Tucholskie, Poland covers a sky area several times the size of the full moon. Also known as the...

Millions of acres of farmland across the country are privately owned, but a small share of it is foreign-owned land sitting idle in many areas. That’s according to new U.S. Department of Agriculture data which shows just how much of the nation’s agricultural land is owned by other countries. The USDA‘s online portal reveals that more than 45 million acres of land are owned by foreign countries, with an original purchase value of over $38 billion. Our neighbor to the north, Canada, has the most agricultural acreage in the United States, at 15.35 million acres. John Hewlett, a farm and...

Explanation: What if you saw your shadow on Mars and it wasn't human? Then you might be the Opportunity rover exploring Mars. Opportunity explored the Red Planet from 2004 to 2018, finding evidence of ancient water, and sending breathtaking images across the inner Solar System. Pictured here in 2004, Opportunity looks opposite the Sun into Endurance Crater and sees its own shadow. Two wheels are visible on the lower left and right, while the floor and walls of the unusual crater are visible in the background. Caught in a dust storm in 2018, Opportunity stopped responding, and NASA stopped trying...

A new 3D map of Uranus is shedding light on one of the solar system's most mysterious planets. Using NASA's James Webb Space Telescope, scientists observed the ice giant for nearly a full rotation, revealing the inner workings of its upper atmosphere for the first time. The team, led by Paola Tiranti from Northumbria University, mapped out the temperature and density of ions in the electrically–charged layer that sits 3,100 miles (5,000km) above the cloud tops.

Modern smart watches can measure an array of health indicators. Step counts and heart rates sit at the simpler end, while VO2 max and blood-oxygen levels are mainly of interest to committed health nuts. The newest addition to the category is heart-rate variability (HRV).As its name suggests, HRV measures not how quickly the heart beats, but how regularly spaced those beats are. With heart rate a lower score is usually better, other things being equal, since it suggests a high level of cardiovascular fitness. When it comes to HRV, though, a higher number—that is, a more irregular pattern—is generally what...

Explanation: Only two days after the February New Moon's annular eclipse of the Sun, a slender lunar crescent poses above the western horizon after sunset in this wintry twilight skyscape. Its nightside faintly illuminated by earthshine, the young Moon is joined by three bright planets in the mostly clear, early evening skies above the village of Kirazli, Turkiye. Inner planet Venus appears closest to the horizon. Near the beginning of its 2026 performance as planet Earth's evening star, brilliant Venus is seen through the warm sunset glare near picture center. Straight above Venus, innermost planet Mercury is easy to spot...

Iranian police officers are gang-raping imprisoned female protesters and then cutting out their uteruses to cover up the horrific torture – before shipping their lifeless bodies home to their families, according to a shocking new report. Prisoners suspected of participating in the nationwide anti-regime demonstrations that shook the nation last month are being terrorized, raped, and slaughtered daily by groups of militant police officers behind bars, an Iranian source told News Nation. “I am most worried about the people who got arrested,” the source, who witnessed the massacre of protesters, said. “They are raping men and women in jail. They...

During his lifetime, Newton kept his theological works highly private, which may have been in part to avoid conflict with the Anglican Church. The two were at odds because the Church preached the doctrine of the Trinity, something which Newton strongly rejected under the belief that God has no equals. When Newton died in 1727 without a will, a pair of distant relations took possession of all his private papers, and chose to keep the work hidden from the public because they were devout Anglicans who didn't want to publicize what they saw as heretical material.Snip Newton reached his end...

Explanation: "A ghost in the Milky Way…” says Christian Bertincourt, the astrophotographer behind this striking image of Barnard 93 (B93). The 93rd entry in Barnard’s Catalogue of Dark Nebulae, B93 lies within the Small Sagittarius Star Cloud (Messier 24), where its darkness stands in stark contrast to bright stars and gas in the background. In some ways, B93 is really like a ghost, because it contains gas and dust that was dispersed by the deaths of stars, like supernovas. B93 appears as a dark void not because it is empty, but because its dust blocks the light emitted by more...

NASA today released its final investigation report on the causes behind the Starliner thruster issues during that capsule’s only manned mission in ISS, issues that almost prevented the spacecraft from docking successfully and could have left it manned and out-of-control while still in orbit. Starliner docked to ISS in 2024.You can read the report here [pdf]. NASA administrator Jared Isaacman made it clear in his own statement that the Starliner incident was far more serious than originally let on. “To undertake missions that change the world, we must be transparent about both our successes and our shortcomings. We have to...
