Astronomers have discovered Andromeda XXXVI, an ultra-faint dwarf galaxy orbiting Andromeda, containing stars over 12 billion years old.

Found through a collaboration between an amateur stargazer and researchers, this dim “fossil” offers rare insight into early cosmic structure formation.

Dominated by dark matter, it highlights both the origins of galaxies—and the enduring value of human observation in modern astronomy

The discovery of a third dark matter–free galaxy, DF9, strengthens the “bullet dwarf” collision theory, suggesting that violent cosmic impacts can separate visible matter from its dark matter halo.

Like earlier finds DF2 and DF4, this ultra-diffuse galaxy shows gravitational behavior explained only by its stars, not unseen mass. The alignment of these galaxies hints at debris from an ancient collision, offering rare evidence that dark matter is a distinct, physical substance—and reshaping our understanding of galaxy formation and the structure of the universe.

The Vera C. Rubin Observatory, powered by its cutting-edge LSST Camera, has already uncovered thousands of new asteroids—including fast-spinning objects that challenge existing theories.

One standout, 2025 MN45, rotates so quickly it suggests unexpected internal strength, reshaping how scientists understand asteroid structure.

With a real-time alert system tracking millions of events nightly, this marks a shift toward time-domain astronomy—transforming planetary defense and our view of a dynamic universe

Research from Washington University in St. Louis suggests early-universe neutrinos may have transformed into an unknown form of dark radiation.

This hidden component could explain cosmological anomalies and help resolve the Hubble tension, where measurements of the universe’s expansion don’t align.

A brief look at how unseen physics might be shaping the cosmos.

Astronomers have discovered WISPIT 2, a young star system 437 light-years away, offering a rare real-time view of how planetary systems form. Using advanced instruments like the Very Large Telescope, scientists directly imaged two massive gas giants still emerging within a protoplanetary disk of gas and dust.

This marks only the second time multiple planets have been observed forming simultaneously. Because the host star closely resembles our Sun, WISPIT 2 provides a powerful window into the early evolution of our own solar system—while hints in the disk suggest even more hidden worlds may still be taking shape.

Researchers are exploring a new approach to terraforming Mars using engineered aerosols—such as graphene disks or aluminum particles—to trap heat and amplify the greenhouse effect. Unlike extreme proposals like nuclear detonations, this method relies on controlled atmospheric modification.

Simulations suggest this strategy could raise Mars’ temperature by up to 35°C, potentially allowing liquid water to exist on the surface within decades. This episode examines the science behind the concept, its uncertainties, and what it could mean for the future of human exploration on Mars.

New research from ETH Zurich suggests that Earth formed almost entirely from inner solar system material. Isotopic evidence shows that less than 2% came from beyond Jupiter, challenging long-held theories about external contributions.

This implies that Jupiter acted as a barrier early on—meaning key ingredients like water may have originated locally, reshaping our understanding of planetary formation.

Data from the James Webb Space Telescope reveals a new class of exoplanets—molten worlds with global magma oceans and toxic, sulfur-rich atmospheres. One example, L 98-59 d, appears to sustain its thick atmosphere through continuous volcanic degassing.

This discovery suggests that planets around red dwarf stars may follow a third evolutionary path, expanding our understanding of how diverse—and extreme—alien worlds can be.

Astronomers analyzing data from the Hubble Space Telescope made a surprising discovery: a comet that literally reversed its spin. Known as Comet 41P/Tuttle–Giacobini–Kresák, this small, fragile object reacts dramatically as it nears the Sun. Jets of gas erupt from its surface like uneven thrusters, slowing its rotation until it flips direction entirely.

This rare phenomenon reveals how unstable and rapidly evolving comets can be—and suggests 41P may eventually break apart. It also highlights how revisiting old NASA data can still unlock entirely new discoveries about our solar system.
