It’s springtime on Mars and the mysterious polygons are in bloom, a new image from the orbiting High Resolution Imaging Experiment (HIRISE) camera shows. Recorded on March 30, 2022, the image reveals a patchwork of white zig-zags cracking across the Martian soil at high latitudes, with occasional sprays of black and blue mist fanning out … Read more
Humans have been expressing thoughts with language for tens (or perhaps hundreds) of thousands of years. It’s a hallmark of our species — so much so that scientists once speculated that the capacity for language was the key difference between us and other animals. And we’ve been wondering about each other’s thoughts for as long … Read more
Jupiter’s innards are full of the remains of baby planets that the gas giant gobbled up as it expanded to become the behemoth we see today, scientists have found. The findings come from the first clear view of the chemistry beneath the planet’s cloudy outer atmosphere. Despite being the largest planet in the solar system, … Read more
Physicists have created a system of two connected time crystals, which are strange quantum systems that are stuck in an endless loop to which the normal laws of thermodynamics do not apply. By connecting two time crystals together, the physicists hope to use the technology to eventually build a new kind of quantum computer. “It … Read more
A coronal mass ejection (CME) is a vast cloud of electrically charged particles from the sun’s upper atmosphere or corona that’s heated to enormous temperatures and launched with a huge burst of speed by the energy released in a solar flare. These hot blobs of plasma can have spectacular effects on planets that lie in … Read more
Whether you call our planet the Earth, the world or a terrestrial body, all of these names have an origin story deep in history. Like many names of solar system objects, Earth’s original namer is long lost to history. But linguistics provide a few clues. Ertha is an approximate spelling for “the ground” (meaning, … 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
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
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
