Scientists are hunting for "Decaying Dark Matter" in the X-ray light of galaxy clusters. If found, a tiny spectral line could reveal the nature of 85% of the universe. We know neutrinos exist—ghostly particles that pass through Earth constantly. But standard "active" neutrinos are too light to be Dark Matter.

ALMA is now fully equipped. New German-made amplifiers have unlocked "Band 2," allowing us to see the birth of stars and the chemistry of life like never before. To hear the faint whispers of the universe, you need an amplifier that doesn't add its own noise. Fraunhofer IAF developed new Low-Noise Amplifiers (LNAs) using Indium Gallium Arsenide (InGaAs). They operate at a chilling 22 Kelvin noise temperature—unmatched worldwide.

Using JWST, astronomers have looked back in time at 877 "Milky Way Twins" to chart exactly how our galaxy evolved from a chaotic youth to a majestic spiral. By observing "twins" of the Milky Way at different distances (and thus different ages), the team reconstructed our galaxy's baby photo album. The Discovery: Galaxies like ours build their dense central cores first. Only later does gas settle into the outer regions to form the wide, flat spiral disk we live in today.

A decade of data reanalysis suggests Saturn's largest moon isn't an open ocean world. It's a viscous, icy mix of "Arctic sea ice" and aquifers. Researchers revisited Cassini data and found something previous models missed: Energy Dissipation. If Titan had a global ocean, it would flex easily. But the data shows massive energy loss as heat. This requires friction.

NASA's IMAP spacecraft and its novel CoDICE instrument have begun their mission to chart the invisible magnetic bubble that protects us from the galaxy. The Sun blows a constant "wind" of particles that inflates a bubble called the Heliosphere. This bubble protects us from high-energy galactic radiation.

Astronomers using the Australian SKA Pathfinder have found a millisecond pulsar locked in a deadly dance with a companion star, eclipsing its signal for nearly half its orbit. Millisecond Pulsars (MSPs) are old neutron stars spun up by eating material from a companion. When they turn on, their intense radiation begins to blast their partner.

Conventional AI is powerful but mysterious. A new "Interpretable AI" framework called CKAN is revealing the physical laws hidden inside galaxy clusters. When galaxies collide, normal matter (gas) drags due to friction. Dark matter usually passes right through (ghostly). However, if Dark Matter interacts with itself (Self-Interacting Dark Matter or SIDM), it should also experience drag. This would cause the Dark Matter halo to separate from the galaxies.

Are "Hycean" exoplanets really ocean worlds? Or are they just balls of magma in disguise? A new metric called the "Solidification Shoreline" suggests the latter. The researchers from Cambridge developed a new way to check these planets. They plotted the star's temperature against the energy hitting the planet (instellation flux). They found a boundary called the Solidification Shoreline.

Why our first contact with aliens likely won't be a handshake, but a scream from a dying civilization. "Eschatian" comes from eschatology, the study of the end of the world. Kipping argues that civilizations in a terminal phase—unstable, collapsing, or dying—might produce anomalous, high-energy signals. A stable civilization might use efficient, quiet fiber optics. A dying one might blast the cosmos with the heat of a burning planet, a desperate radio scream, or the debris o

Dust clouds usually hide newborn planets. But Gaia has found a way to "feel" them, revealing 32 new baby star systems in our galaxy. Normally, astronomers use telescopes like ALMA to look at the dust (orange/purple). But dust hides planets. It's like trying to find a pebble in a sandstorm. Gaia looks through the problem by ignoring the dust and watching the star itself.

Traditional SETI looks for technology like ours. A new study suggests we should look for signals that behave like nature: efficient, distinct, and evolved. The study used a backdrop of 158 real pulsars. Pulsars are natural, high-energy beacons.

Before its final plunge, Cassini tasted dust high above Saturn's rings. The data reveals the rings are not as flat as they look. Cassini collected 1,690 dust spectra. The team found that the dust high above the rings matches the composition of the rings themselves, not interstellar dust.
