Neptune is the farthest planet from the sun and one of two “ice giants” in our solar system. The cold, blue planet is about 30 times farther away from the sun than Earth and takes around 165 Earth years to complete a single orbit around our star. Neptune spins around its axis quicker than Earth, … Read more
Last week, one auction-goer went home well-prepared to face an encounter with the undead after buying a “vampire-slayer kit” dating back to the late 19th century. The kit sold for nearly $15,600 (£13,000) — six times its estimated price, after bids came from around the world. The U.K. buyer brought home a heavy wooden box … Read more
A pulsar is a special kind of neutron star, which is the ultra-dense leftover core of a massive star. Pulsars emit beams of radiation that sweep out in circles as the pulsar spins. When those beams flash over Earth, we see them as regular, repeating pulses of radio emission. “Pulsars are spectacular objects themselves — … Read more
Our species faces a pivotal moment in human history. Either we develop the technology to safely harness the energy needed to escape our planet, or we kill ourselves in some great cataclysm, a stark new study claims. But, the new paper argues, if we can achieve the former and avoid the latter, then we might … Read more
Researchers may have pinpointed the source of a famous supposed alien broadcast discovered nearly a half century ago. The prominent and still-mysterious Wow! Signal, which briefly blared in a radio telescope the night of Aug. 15, 1977, may have come from a sun-like star located 1,800 light-years away in the constellation Sagittarius. “The Wow! Signal … Read more
NASA has photographed the crash site of the mysterious rocket that smashed into the far side of the moon in March, and the unidentified spacecraft left behind a weird double crater that has scientists puzzled. Images of the crash site were taken by NASA’s Lunar Reconnaissance Orbiter (LRO) on May 25 and released on June … Read more
Mercury is the closest planet to the sun and the smallest planet in our solar system. With a diameter of about 3,032 miles (4,880 kilometers), the planet is less than half the size of Earth, which is about 7,926 miles (12,756 km) in diameter. But what it lacks in size, it makes up for in … Read more
Pentagon officials speaking at the first public hearing on UFOs since the 1960s have shown previously classified footage of an unidentified aerial phenomenon (UAP), a split-second video of a metallic sphere zooming across the flight path of a military jet. The object, captured through the cockpit window of an FA-18 fighter jet in 2021, was … Read more
Prehistoric giants used to populate the Earth. These behemoths included mighty dinosaurs, airplane-size pterosaurs, massive crocodiles and snakes, and even armadillos the size of cars. But today, there are just a few big animals on our planet. What happened? Why aren’t there many giants left anymore? First of all, there’s plenty of fossil evidence that … Read more
Antarctica’s so-called Doomsday Glacier is losing ice at its fastest rate in 5,500 years, raising concerns about the ice sheet’s future and the possibility of catastrophic sea level rise caused by the frozen continent’s melting ice. The finding comes from a study of prehistoric sea-deposits found on the shores surrounding the “doomsday” Thwaites Glacier and … Read more
