3I/ATLAS, a mysterious interstellar object racing toward the Sun, is baffling scientists with its speed and origin. Some researchers suggest it could even be alien-made, drawing comparisons to probes ...
High above the Sun’s blazing equator lie its mysterious poles, the birthplace of fast solar winds and the heart of its magnetic heartbeat. For decades, scientists have struggled to see these regions, hidden from Earth’s orbit. With the upcoming ...
NASA’s Magnetospheric Multiscale Mission has uncovered surprising behavior of pickup ions drifting through the solar wind near Earth. These particles, once thought to be minor players, appear capable of generating waves and influencing how the ...
Astronomers using AI have captured a once-in-a-lifetime cosmic event: a massive star’s violent death triggered by its black hole companion. The explosion, known as SN 2023zkd, not only produced a brilliant supernova but also shocked scientists by ...
Lichen from the Mojave Desert has stunned scientists by surviving months of lethal UVC radiation, suggesting life could exist on distant planets orbiting volatile stars. The secret? A microscopic “sunscreen” layer that protects their vital ...
Astronomers have revealed new research showing that millions of new solar system objects are likely to be detected by a brand-new facility, which is expected to come online later this ...
Scientists have identified a new source of energetic particles near the Sun. These definitive observations were made by instruments aboard NASA's Parker Solar Probe, which detected the powerful phenomena as the spacecraft dipped in and out of the ...
WASP-121b may have been born in a frozen zone and later migrated into its current inferno-like orbit. A surprise discovery of methane in the wrong place suggests intense vertical winds are reshaping how we understand planetary ...
A series of studies sheds light on the origins and characteristics of intermediate-mass black ...
Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur ...
Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the ...
Even under intense ultraviolet radiation from giant stars, the raw ingredients for planets can endure. Using Webb s powerful infrared eyes, astronomers examined a young star in the Lobster Nebula and ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

Astronomers have detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf star, offering the clearest evidence yet that icy, life-delivering ...

Astronomers using the James Webb Space Telescope have uncovered mysterious “little red dots” that may not be galaxies at all, but a whole new type of object: black hole stars. These fiery ...

Gravitational-wave astronomy has exploded since 2015, capturing hundreds of black hole and neutron star collisions. With ever-clearer signals, researchers are testing Einstein’s relativity and ...

Astronomers studying an oddball brown dwarf called “The Accident” have finally spotted silane, a long-predicted silicon molecule missing from Jupiter and Saturn’s skies. Its ancient, ...

Scientists from the University of St Andrews have discovered that ions in solar flares can reach scorching temperatures more than 60 million degrees—6.5 times hotter than previously believed. This ...

Astronomers have uncovered a massive new trans-Neptunian object, 2017 OF201, lurking at the edge of our solar system. With an orbit stretching 25,000 years and a size that may qualify it as a dwarf ...

Solar Orbiter has identified the Sun’s dual “engines” for superfast electrons: explosive flares and sweeping coronal mass ejections. By catching over 300 events close to their origin, the ...

Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding ...

Astronomers using the James Webb Space Telescope have uncovered a planet-forming disk shockingly rich in carbon dioxide but nearly devoid of water, upending traditional theories of planetary ...

Astronomers using ALMA have discovered that planet-forming discs are not flat and serene but subtly warped, reshaping our understanding of how planets form. These slight tilts, similar to those seen ...

James Webb has revealed that the Butterfly Nebula hides a complex mix of gemstone-like crystals, fiery dust, and unexpected carbon molecules. The discovery may rewrite how we understand the chemistry ...

Astronomers have directly spotted a rare young planet, WISPIT 2b, still forming within the gap of a dusty ringed disk around a star like our sun—something long theorized but never observed until ...

WISPIT 2b, a gas giant forming around a young Sun-like star, has been directly imaged for the first time inside a spectacular multi-ringed disk. Still glowing and actively accreting gas, the planet ...

Scientists are unraveling the mysteries of "steam worlds"—exoplanets known as sub-Neptunes that are rich in water but orbit so close to their stars that their surfaces are shrouded in ...

A new model called StarryStarryProcess lets scientists map star spots with precision, improving how exoplanets are studied. By factoring in both transits and stellar rotation, it provides richer ...

Astronomers using the Inouye Solar Telescope have captured the sharpest-ever images of a solar flare, revealing coronal loops as thin as 21 km wide. These threadlike plasma structures, imaged during ...

Astronomers have found over 5,000 exoplanets, and now scientists think these distant worlds could unlock one of the universe’s greatest mysteries: dark matter. A new study suggests that ...

Earth may already be broadcasting its presence to alien civilizations without realizing it. A new study shows that our deep-space transmissions, especially those aimed at Mars and interplanetary ...

For years, scientists thought Jupiter’s strange interior was the result of a massive collision in its youth. But new research suggests that the planet’s diffuse, “fuzzy” core wasn’t born ...
