Astronomers have discovered a galaxy nicknamed the "Cosmic Grapes," a rotating disk teeming with at least 15 massive star-forming clumps. Seen as it was just 900 million years after the Big Bang, this galaxy has far more clumps than any theoretical model predicts could exist at this early time, raising new questions about how the first galaxies formed.

For centuries, we've assumed that solar systems form in an orderly way, with the star's equator and the planet-forming disk spinning on the same plane—just like our own. But a new study led by researchers at UC Santa Barbara and UT Austin has found this isn't the case. By surveying 49 young stars, they discovered that a "fair number" emerge already tilted, suggesting misalignment is a natural part of formation, not just a later-life accident.

By combining data from virtually every major space telescope and ground-based observatory, astronomers searching the GOODS-South deep field have found a pair of interacting galaxies, UDF3 and UDF3-2, at a redshift of 2.54. The discovery, led by Sijia Cai of Tsinghua University, reveals that both galaxies are shining in X-rays, but *not* from the cause astronomers usually expect.

An international team led by UT Austin's Cosmic Frontier Center has used JWST to find the unmistakable signature of a supermassive black hole at a record-breaking distance. The discovery, part of the CAPERS survey, provides a unique opportunity to study how these giants grew so massive, so quickly, in the infant universe.

Astronomers have discovered a fascinating object that forces us to rethink how dead stars behave. A white dwarf, J1634+44, located over 3,500 light-years away, is doing something completely unexpected: sending out bright radio pulses. What's truly bizarre is *how* it's pulsing, in a strange rhythm with a weird twist in its waves, a behavior never seen before from a white dwarf.

Before they die as supernovae, the universe's most massive stars (called Wolf-Rayet stars) shed their outer layers in violent gales. When these stars are in a binary pair, their winds collide, creating a cool, dense zone where carbon-rich winds condense into dust—the raw material of our bodies. As the stars orbit, this dust stream is wrapped into a perfect spiral, like water from a sprinkler. We expected Apep to be one of these elegant pinwheels. It was not.

On the slopes of Martian mountains lie features that look like frozen, dust-covered honey. For years, scientists thought they were mostly rock with a little ice. Now, a new paper in *Icarus* confirms these slow-moving glaciers are the opposite: they contain more than 80% pure water ice, hidden under just a thin veil of rock and dust. This finding provides a clearer picture of Mars's climate history and identifies a critical resource for human exploration.

For decades, scientists have operated on the assumption that dark energy—the mysterious force pushing the universe apart—is a constant. But mountains of new data, especially from supernovae, are challenging this. Evidence suggests dark energy might be evolving, and its force has weakened since the universe's inception. If it's true, what does this mean for the future of the cosmos?

The discovery was made around HOPS-315, a star 1,370 light-years away that is a cosmic infant—only 100,000 to 200,000 years old. Using the combined power of the James Webb Space Telescope and the ALMA telescope network, astronomers peered deep into the gas disk around the protostar and found the key ingredients for rocky planets actively condensing from gas into solid specks.

Galaxy clusters are the largest known gravitationally-bound structures in the universe, containing thousands of galaxies. They are excellent laboratories for studying cosmic evolution. A team led by Keegan Trehaeven of Rhodes University used the powerful MeerKAT and uGMRT radio telescopes to study Abell 3558, a massive cluster 1.48 quadrillion times the mass of our sun. Their detailed study revealed that the diffuse radio emission at its center is a "peculiar" radio mini-halo

When you look at the night sky, you can see the "Seven Sisters" (Pleiades) and the V-shaped Hyades near the constellation Orion, whose "sword" contains the Orion Nebula. For centuries, we've known them as three separate star clusters. But new research from the University of Bonn and IASBS in Iran suggests they are all part of the same story—a story of how star clusters are born, how they age, and how they die.

For decades, scientists have hunted for lithium in Mercury's thin exosphere. Its presence was predicted, but every attempt to find it failed. A new study from the Austrian Academy of Sciences finally found the "smoking gun" by using a fresh angle: they stopped *looking* for the atoms and started *listening* for the magnetic waves they create.
