JWST reveals a distant early‑universe galaxy with unexpected features that upend traditional ideas of how galaxies form. Using the James Webb Space Telescope, astronomers have identified a barred spiral galaxy that pushes the boundaries of how early...

JWST spots three active black holes in one distant galaxy, revealing a rare view of early massive black‑hole system formation. Using the James Webb Space Telescope, astronomers have identified three massive black holes that are actively pulling in gas...

Astronomers have detected signs of a planet potentially formed from the debris of a dead star, offering a rare glimpse into a celestial rebirth. Astronomers have identified a potential “phoenix” world orbiting a white dwarf, a discovery that suggests...

New impact simulations are reshaping our understanding of moon formation, providing researchers with vital clues to finally pin down when the event occurred. New Simulations Challenge Long-Held Theories on the Moon’s Violent Origins For decades, the...

A private mission to study Venus is currently on hold, awaiting the debut of Rocket Lab’s next-generation launch vehicle to begin its interplanetary journey. The inaugural private mission to Venus has encountered a scheduling setback, as the project...

A newly discovered star orbiting Sagittarius A* could provide astronomers with a rare, groundbreaking way to measure the Milky Way’s central black hole. Astronomers have uncovered a celestial speedster named S301, a star hurtling through the extreme...

Astronomers have detected an unusual event in a distant galaxy that could finally reveal what happens when two black holes collide. Astronomers have uncovered evidence of a rare cosmic spectacle unfolding at the heart of the galaxy Mrk 501: a potential...

Mackay-Champion. “It raises exciting possibilities for how common such systems might be on rocky planets beyond our solar system.” A simulation of Mars’ internal temperature structure, highlighting the depths where rocks may remain solid or begin to...

Hubble and Webb track a star’s subtle motion to reveal Omega Centauri’s first hidden black hole, confirming decades‑old predictions of a missing population. A joint analysis of more than two decades of Hubble observations and the latest measurements...

Global timekeepers may abolish the leap second by 2027, allowing atomic clocks to drift further from Earth’s rotation in a major shift for global timekeeping. Global timekeeping authorities are preparing for a potential shift in how we synchronize our...

New data shows Pluto’s atmosphere is shifting unexpectedly, sparking fresh investigations into the dwarf planet’s evolving climate. New observations suggest Pluto’s tenuous atmosphere is beginning to thin as the dwarf planet drifts farther from the...

A new lab study finds sperm struggle to navigate and fertilize eggs in simulated microgravity, hinting at hidden reproductive challenges for long-term space travel. For decades, space agencies have focused on propulsion, radiation shielding, and...

New simulations reveal the Moon may have formed almost intact within mere hours of a massive collision between Earth and the protoplanet Theia. For decades, the dominant theory of lunar formation has painted a picture of a gradual, messy process: a...

is significantly higher than earlier studies suggested. The knots themselves are immense; each one could contain our solar system’s planetary region ten times over. The striking uniformity of these knots suggests they were formed by a consistent...

South Africa’s MeerKAT telescope has detected the first radio signals from an exoplanet, offering a groundbreaking method to study alien magnetic fields. Astronomers have achieved a long-awaited milestone in planetary science by successfully isolating...

pushed into safer orbits after the star consumed other, closer worlds in the system. Implications for the Future of Our Solar System These findings provide a glimpse into the distant future of the Sun. In roughly 5 billion years, the Sun will initiate...

Astronomers have detected a unique molecular signature of alcohol in a distant star-forming region, marking a surprising new discovery in space chemistry. Astronomers have achieved a milestone in astrochemistry, identifying a rare form of alcohol in...

“Carbon, hydrogen and oxygen are all things that have been previously found in atmospheres of giant planets outside our solar system, but ammonia is something almost never detected before,” said lead author Giannina Guzmán Caloca. “It’s an entirely new...

Astronomers have discovered a rare baby planet less than 1 million years old, providing a unique glimpse into the earliest stages of planetary formation. Astronomers have confirmed the existence of Elias 2-24 b, a massive infant world that currently...
