"The large-scale homogeneity of the universe makes it very difficult to believe that the structure of the universe is determined by anything so peripheral as some complicated molecular structure on a minor planet orbiting a very average star in the outer suburbs of a fairly typical galaxy."

The Europa Clipper Mission Tests it Radar Instrument at Mars

Universe Today - Wed, 08/13/2025 - 5:47pm

NASA's Europa Clipper, the largest interplanetary probe, tested its radar during a Mars flyby. The results show the kind of detailed imagery the probe will capture once it arrives at Jupiter’s moon Europa.

This Could Prevent Rovers From Getting Stuck In Sand Or Dust

Universe Today - Wed, 08/13/2025 - 5:47pm

Engineers at the University of Wisconsin-Madison uncovered a critical flaw in how lunar and Martian rovers are tested on Earth. Simulations revealed that test results have been misleading for decades because researchers only adjusted rover weight to simulate low gravity—but ignored how Earth’s gravity affects the terrain itself. Using a powerful simulation tool called Chrono, the team showed that sandy surfaces behave very differently on the Moon, where they’re fluffier and less supportive.

Astronomers Detect Most Distant Fast Radio Burst Ever

Universe Today - Wed, 08/13/2025 - 5:47pm

Astronomers have detected a fast radio burst (FRB) from when the Universe was just 3 billion years old, a remarkable achievement that opens new windows into the early universe and the mysterious phenomena that shaped it.

Stellar Flares Unveil Hidden Magnetic Secrets of TRAPPIST-1

Universe Today - Wed, 08/13/2025 - 5:47pm

A team of astronomers using the James Webb Space Telescope have achieved a breakthrough in understanding TRAPPIST-1, the famous red dwarf star hosting seven Earth sized planets. By analysing stellar flares, the team discovered that flares cause dark magnetic features on the star's surface to disappear, creating persistent brightening effects. This represents the first-ever measurement of magnetic feature spectra on an M8 dwarf star.

Lucy Could Visit An Additional Sub-km Asteroid With A Course Correction

Universe Today - Wed, 08/13/2025 - 5:47pm

Lucy is already well on its way to Jupiter’s Trojan asteroids. But that doesn't mean that it can’t make some improvements to its trajectory along the way. A new paper suggests it might be possible to nudge Lucy into a slightly different orbit, allowing it to pass an as-yet-undiscovered asteroid sometime during its exploration of the L5 cloud of Trojan around Jupiter. If completed, it could lend an entirely new research target to Lucy’s repertoire and further define the differences between the two Trojan clouds.

Planning for the Ultimate Space Mission

Universe Today - Wed, 08/13/2025 - 5:47pm

What if we could send a probe smaller than a paperclip, yes a paperclip to visit a black hole? It sounds impossible, but one scientist believes this extraordinary mission could become reality within our lifetimes. Astrophysicist Cosimo Bambi has outlined a bold plan to launch microscopic spacecraft toward the nearest black hole, potentially revolutionising our understanding of physics and Einstein's theory of general relativity. While the technology doesn't exist today and would cost trillions, within the next 20-30 years it could become a reality!

Astronomers Spot the Earliest Confirmed Black Hole at Cosmic Dawn

Universe Today - Wed, 08/13/2025 - 5:47pm

An international team of astronomers led by The University of Texas at Austin’s Cosmic Frontier Center has confirmed the most distant black hole ever observed. Located at the center of the galaxy CAPERS-LRD-z9, this black hole existed 13.3 billion years ago, just 500 million years after the Big Bang. As such, it provides a unique opportunity to study the structure and evolution of the period known as "Cosmic Dawn."
