As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction. Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision.

Their rare orbital relationship and enormous, lightweight atmospheres could provide valuable clues about how some of the strangest planets in the galaxy come to exist. Fri, 26 Jun 2026 21:09:31 EDT https://www.sciencedaily.com/releases/2026/06/260626124659.htm https://www.sciencedaily.com/releases/2026/06/260623083146.htm What if consciousness isn’t limited to brains like ours? Philosophers Eric Schwitzgebel and Jeremy Pober argue that consciousness could arise in many different forms of life, even in beings built from radically different materials than those found on Earth. Drawing on the vastness of the universe and the likely existence of countless alien civilizations, they suggest it would be surprisingly Earth-centric to assume that only Earth-like biology can support conscious experience. Wed, 24 Jun 2026 10:49:57 EDT https://www.sciencedaily.com/releases/2026/06/260623083146.htm https://www.sciencedaily.com/releases/2026/06/260623083121.htm Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The researchers say future missions should focus not only on finding life, but also on understanding how signs of life could be missed.

The finding confirms key theories about how massive stars forge the elements that help build planets, worlds, and life. Sat, 27 Jun 2026 21:14:15 EDT https://www.sciencedaily.com/releases/2026/06/260616103133.htm https://www.sciencedaily.com/releases/2026/06/260613034225.htm Using the Keck Observatory, astronomers measured the spins of dozens of giant planets and brown dwarfs orbiting distant stars. They found that giant planets can spin faster than much more massive brown dwarfs, challenging simple assumptions about mass and rotation. The results suggest that magnetic fields and formation processes play a major role in determining how fast worlds end up spinning.

Using the James Webb Space Telescope, astronomers discovered that WASP-94A b’s mornings are filled with clouds made of rock-like minerals, while its evenings are surprisingly clear. The finding gave scientists their clearest look yet into the planet’s atmosphere and revealed it’s far more Jupiter-like than previously believed. Wed, 27 May 2026 06:24:22 EDT https://www.sciencedaily.com/releases/2026/05/260527023212.htm https://www.sciencedaily.com/releases/2026/05/260525000455.htm Scientists believe a dust-filled ring just outside Jupiter acted like a cosmic “planetesimal factory,” producing multiple generations of early space rocks with very different compositions. The discovery may finally explain the origins of several mysterious meteorite types that have survived since the birth of the Solar System. Tue, 26 May 2026 01:48:02 EDT https://www.sciencedaily.com/releases/2026/05/260525000455.htm https://www.sciencedaily.com/releases/2026/05/260522023120.htm NASA scientists were stunned when a strange radio signal from the Sun refused to fade away. Instead of lasting a few hours or days like normal solar radio bursts, this one persisted for an astonishing 19 days — shattering the previous record. Using a fleet of spacecraft spread across the solar system, researchers tracked the mysterious signal to a massive magnetic structure on the Sun called a helmet streamer.

Scientists analyzing gravitational-wave signals from dozens of black hole collisions found evidence that the heaviest black holes are likely “cosmic recyclers” — formed through repeated smashups inside incredibly crowded star clusters. These violent chain reactions appear to create a distinct class of rapidly spinning black holes that stand apart from ordinary ones formed by dying stars.

By analyzing millions of stars, the system has confirmed over 100 exoplanets, including 31 brand-new worlds, and identified thousands more promising candidates. What makes this especially exciting is the discovery of rare and extreme planets, like those that whip around their stars in less than a day and others lurking in the mysterious “Neptunian desert,” where planets are thought to be scarce.

After detecting ripples in space-time, scientists spotted a fast-fading red glow that initially looked like a rare kilonova—the kind of collision that forges gold and uranium. But just days later, the signal shifted, behaving more like a supernova, leaving researchers puzzled. Now, some think they may have witnessed something never seen before: a “superkilonova.” Fri, 24 Apr 2026 10:02:52 EDT https://www.sciencedaily.com/releases/2026/04/260423031532.htm https://www.sciencedaily.com/releases/2026/04/260423031528.htm Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

Advanced simulations suggest that carbon and hydrogen, under crushing pressures and scorching temperatures, can form a strange hybrid phase—part solid, part fluid—where hydrogen atoms spiral through a rigid carbon framework. This unusual “superionic” structure could reshape how heat and electricity flow inside these distant worlds, potentially helping explain their mysterious magnetic fields.

Researchers found that during the planet’s earliest formation, oxygen had to be in an extremely narrow “Goldilocks zone” for two life-essential elements, phosphorus and nitrogen, to stay where life could use them. Too much or too little oxygen, and those ingredients could be lost or trapped deep inside the planet. This could reshape the search for life by showing that water alone is not enough.

Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many have already been swallowed. The likely cause is a gravitational tug that drags planets inward until they break apart or fall into the star. It’s a dramatic glimpse into the chaotic final stages of planetary systems.

Instead, it’s noticeably skewed, and researchers now think they understand why. By analyzing years of data from the Cassini spacecraft, scientists found that a key region where solar particles enter Saturn’s atmosphere is consistently shifted to one side. This distortion appears to be driven by the planet’s rapid spin combined with a thick cloud of charged particles coming from its moon Enceladus.

Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ magnetic fields. These structures act like built-in space weather monitors, revealing how energetic particles affect nearby planets. The findings could reshape how we think about whether planets around these common stars can survive—or even host life.

Now, thanks to highly precise observations from Japan’s XRISM space telescope, scientists have finally uncovered the source: a hidden white dwarf companion pulling in material and generating extreme heat. This discovery not only solves a 50-year-old mystery surrounding Gamma Cassiopeiae, but also confirms the existence of a long-predicted type of binary star system.

Using new data from ESA’s Gaia mission and NASA archives, researchers pinpointed worlds in the “habitable zone,” where temperatures could allow liquid water to exist. Some of the most intriguing targets include nearby systems like TRAPPIST-1 and Proxima Centauri, offering tantalizing possibilities just dozens of light-years away.

Using cutting-edge supercomputer simulations, researchers discovered that stellar rotation plays a powerful role in mixing elements across a previously unexplained barrier inside the star.

Using NASA’s James Webb Space Telescope, researchers found the planet is far cooler than expected for a bare rock, hinting at a heat-distributing atmosphere above a churning magma ocean. This strange world—where a year lasts just over 10 hours and one side is locked in eternal daylight—may even be rich in volatile materials, behaving like a “wet lava ball.” Sun, 22 Mar 2026 04:19:46 EDT https://www.sciencedaily.com/releases/2026/03/260322020255.htm https://www.sciencedaily.com/releases/2026/03/260317190802.htm Astronomers have identified a strange new kind of exoplanet that challenges how scientists classify worlds beyond our Solar System. The planet, L 98-59 d, appears to contain a vast ocean of molten rock beneath its surface that traps large amounts of sulfur deep inside. Observations from the James Webb Space Telescope revealed unusual sulfur-rich gases in its atmosphere and a surprisingly low density for its size.

Observations from JWST revealed that this haze may be one of the largest ever detected, possibly stretching as wide as Earth itself. The planet’s low density and close orbit don’t match existing models of how gas giants form or survive. Now, researchers are left with more questions than answers about how such a strange world came to be.

Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a frozen desert. NASA’s twin-spacecraft ESCAPADE mission aims to watch this process in action by measuring how the solar wind interacts with Mars’ fragile magnetic environment. The findings could reveal how Mars lost its habitability—and help prepare humans for future missions there.

A seemingly ordinary sun-like star suddenly began flickering wildly, puzzling scientists until they realized the strange dimming was caused by vast clouds of hot dust and debris drifting across the star. The most likely explanation is a violent planetary collision—two worlds smashing together and scattering glowing material throughout the system.

For years, scientists wondered how these delicate two-lobed shapes could form without violent collisions tearing them apart. Now researchers at Michigan State University have recreated the process in a powerful new simulation, showing that simple gravitational collapse can naturally produce these cosmic “snowmen.” Mon, 23 Feb 2026 02:47:10 EST https://www.sciencedaily.com/releases/2026/02/260222085206.htm https://www.sciencedaily.com/releases/2026/02/260213223857.htm Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky planets close in and gas giants farther out — the same pattern seen in our own Solar System and hundreds of others. And at first, that’s exactly what they saw. But new observations revealed a surprise: the outermost planet appears to be rocky, not gaseous.
