Researchers have found that the thick and hazy atmosphere enveloping Saturn's largest moon, Titan, behaves in a very peculiar way. As detailed in a new paper published in The Planetary Science Journal, a team of scientists analyzed 13 years' worth of thermal infrared observations recorded by NASA and the European Space Agency's Cassini-Huygens mission. Their finding: that Titan's atmosphere wobbles like a gyroscope as it shifts with the seasons of its nearly 30 Earth-year cycle, instead of spi

Images sent back by NASA's Viking spacecraft in the 1970s revealed some unusual streaks stretching across the arid landscapes of Mars. The sighting had scientists excited about the possibility of free-flowing water on an otherwise desolate planet. The streaks — which, at times, were thousands of feet long — appeared much darker, contrasting against the mostly monotonal, surrounding hills, looking as if somebody had spilled an enormous glass of water on a patch of hilly sand. But decades later,

Saturn’s most metal moon just got more intriguing. On Titan, clouds of methane unleash a cold, oily rain—very different from the water-based downpours we see on Earth. For the first time, scientists have collected evidence of cloud convection in Titan’s northern hemisphere, observing the moon’s methane clouds shifting over time above its eerie lakes. By combining data from the Webb space telescope and the Keck Observatory in Hawaii, a group of scientists observed Titan’s clouds rising to higher

On March 18, 2024, the Sun swung a large bubble of plasma toward the direction of Mars. The eruption of the solar storm led to an auroral display across the Martian sky, which glowed with a greenish hue. A group of scientists used the Perseverance rover to look up at the sky and capture Mars’ visible aurora for the first time. Scientists used Perseverance’s SuperCam spectrometer and Mastcam-Z camera to observe a visible aurora on Mars, identifying the exact spectral line causing the green emiss

Astronomers have made an intriguing discovery that could upend everything we know about the structure of the universe and its expansion. Scientists recently found that dark energy, the mysterious form driving the accelerating expansion of the universe, could be weakening over time. The findings could undermine the existing standard cosmological model of the universe called the lambda-cold dark matter (LCDM) model, which takes dark energy, ordinary matter, and cold dark matter — a hypothetical

The distinctive chirps of singing cicadas are a highlight of summer in regions where they proliferate; those chirps even featured prominently on Lorde's 2021 album Solar Power. Now, Japanese scientists at the University of Tsukuba have figured out how to transform cicadas into cyborg insects capable of "playing" Pachelbel's Canon.

Humans have been pondering the existence of life beyond Earth since ancient times. In the 1900s, scientists began actively searching for proof. Needless to say, we still haven’t found any. Although it’s only been a number of decades and technology is advancing every day, what if we continue to come up empty-handed? In a study published Monday in The Astronomical Journal, an international team of researchers tackled this question by arguing that what we don’t find can still be deeply informative

Scientists are suggesting there may be a brand new type of life — or, at least, that one existed back in the day. In a new, yet-to-be-peer-reviewed paper, scientists from the University of Edinburgh in Scotland argue that the massive and mysterious tubelike fossils known as "prototaxites" deserve their own life form classification because, basically, they're too weird to belong to any other.
