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.

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 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.

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!

NASA has selected six companies to produce studies focused on lower-cost ways to launch and deliver spacecraft of various sizes and forms to multiple, difficult-to-reach orbits. The firm-fixed-price awards comprise nine studies with a maximum total value of approximately $1.4 million.

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."

Venus, often called Earth's twin, remains one of the most mysterious planets in our Solar System. While it's similar in size to Earth, Venus spins incredibly slowly and backwards compared to other planets. It also lacks a moon, unlike Earth and Mars. Now, new research explores whether a massive asteroid impact in Venus's early history could explain these puzzling characteristics.

3D printing is going to be a critical technology in space exploration, both for its ability to create almost any object, but also because it can utilize in-situ resources, at least in part. However, the more of those space resources are used in a print, the more the mechanical properties change from that on Earth, leading to problems with tensile or compressive strength. But a new paper from researchers at Concordia University hit a new milestone of how much lunar regolith can be used in a mixed feedstock for additive manufacturing, making it possible to use even more locally sourced material, and saving more launch cost, than ever before.

A mysterious visitor from another star system is putting on a spectacular show as it streaks through our Solar System, shedding tons of ancient dust and revealing secrets from the depths of interstellar space. Using the Hubble Space Telescope, a team of astronomers have captured unprecedented details of 3I/ATLAS—only the third confirmed object from beyond our Solar System as it awakens under our Sun's warmth, offering a rare glimpse into alien worlds billions of kilometres away.

Astronomers from Brazil and the UK have detected what could be the most massive black hole ever found. It's about 36 billion solar masses, which is a stunning 10,000 times more massive than Sagittarius A*, the monstrous supermassive black hole at the heart of the Milky Way. This behemoth is about 5 billion light-years away.

White dwarfs are the stellar remnants left behind by stars after they run out of hydrogen and cease fusion. Only a small number of them are "high-mass white dwarfs" more massive than the Sun. New research indicates that these massive white dwarfs are the result of mergers.

It’s that time of year once again. August sees warm nights, with late summer campers out awaiting that ‘Old Faithful’ of annual meteor showers: the August Perseids. While 2025 also sees the shower peaking right around Full Moon, don’t despair; with a little bit of planning and patience, you can still catch this shower at its best.

Everybody sees the Sun.
