NASA has certified a helicopter-based lander training course in Colorado’s Rocky Mountains to prepare Artemis astronauts for Moon missions. The high-altitude terrain creates lunar-like visual illusions, forcing pilots to master landings in dusty, slope-filled conditions. Over two dozen astronauts have now trained in this challenging, realistic simulation.

NASA’s Perseverance rover has uncovered iron-rich minerals in Jezero Crater rocks that on Earth often link to microbial activity. The discovery suggests Mars’ lake basin may have been more hospitable than thought. Still, scientists caution that only Earth-based analysis can confirm whether these are true biosignatures.

October 2025 will feature a Harvest Supermoon, appearing larger and brighter than usual. Known for its cultural importance and beauty, this full moon offers the best views at moonrise in open skies. Skywatchers can enjoy a rare and memorable moment.

LIGO has detected GW250114, the loudest gravitational-wave signal yet, marking ten years since its first breakthrough. The event confirmed Einstein’s relativity, Hawking’s horizon theorem, and Kerr’s spinning black hole model. By capturing the merger of two 32-solar-mass black holes, scientists gained the clearest view of black hole physics, offering new insight…

Italian astronomers using the Hubble Space Telescope have discovered a white dwarf orbiting a blue straggler star in the globular cluster 47 Tucanae, located 15,300 light-years away. The rare system, among the youngest detected, sheds light on stellar mass transfer and offers vital clues to the evolution of binary stars in dense clusters.

Astronomers have spotted GRB 250702B, a gamma-ray burst that erupted several times over two days—something never seen before. Detected by NASA’s Fermi and China’s Einstein Probe, the event defies current models of collapsing stars or black holes, hinting at an entirely new cosmic phenomenon.

Perseverance rover snaps turtle-shaped rock in Jezero Crater, a geologic oddity shaped by erosion and human pareidolia. The picture was snapped on Sol 1,610, August 31, 2025, at Jezero Crater, by the rover’s Sherloc and Watson instruments, fitted to its robotic arm, which capture visible and ultraviolet images of rock surfaces.

A Southwest Research Institute study reveals that chasing interstellar comets like 3I/ATLAS is achievable with current rockets and instruments. Such missions could collect data on comet nuclei and comae, providing clues to the formation of other star systems. International collaborations make these rare, high-value missions increasingly realistic.

NASA’s InSight mission uncovered Mars’ mantle as chaotic and fractured, resembling a Rocky Road brownie rather than a layered planet. Seismic data revealed ancient fragments, some over 4 km wide, preserved by a rigid crust for more than four billion years. The findings offer fresh insights into Mars’ explosive past and the evolution of rocky […]

Astronomers discovered Comet Lemmon (C/2025 A6) in January, and it could soon become visible to skywatchers. Passing closest to Earth on October 20, 2025, the comet may brighten to binocular range or possibly to the naked eye. Its evolving coma and tail promise an exciting celestial show.

Astronomer David Kipping has proposed TARS, a sunlight-driven space slingshot. Using reflective panels spun in space, it can fling small probes at escape speed. Though Alpha Centauri is over a thousand years away, this simple, fuel-free idea could pave the way for future interstellar missions.

Astronomers once thought the universe’s first stars were only massive giants. New simulations and lab experiments reveal turbulence and early chemistry allowed smaller, Sun-like stars to form too. This discovery reshapes our view of cosmic dawn, showing the first stellar generation was more diverse than previously believed.

The first study to utilise microscopic damage on sauropod dinosaur teeth, a method known as Dental Microwear Texture Analysis (DMTA), has shed light on the feeding habits and locomotion of herbivores 150 million years ago, according to new findings reported on September 7, 2025, by Freie Universität Berlin.

The goal of SpaceX’s Starlink project is to transmit broadband internet from orbit. With the most recent launch, the network now has 28 satellites, connecting far-flung areas across the globe. About an hour after liftoff, these satellites effortlessly inserted themselves into their orbits after separating from the rocket’s second stage.

New research challenges the idea that 55 Cancri e, once dubbed a “diamond planet”, is rich in carbon. Re-analysing telescope data, scientists concluded that the host star has a lot more oxygen than originally believed, making the possibility that its planet formed with a carbon-dominant atmosphere less likely.

NASA’s Webb Telescope imaged the Lobster Nebula (NGC 6357), 5,500 light-years away. Its young star cluster, Pismis 24, contains giant stars carving glowing gas pillars. Pismis 24-1, once thought to be one supermassive star, is a triple system with stars up to 74 times the Sun’s mass.

Astronomers have discovered that planets can survive without stars, drifting as rogue or hypervelocity worlds. Some are flung into space by black holes, while others are displaced by gas giants. On some of these rogue worlds, the idea goes, there might be oceans beneath icy crusts, where life, at least life at a microbe level, […]

Exoplanets are planets orbiting stars outside our solar system, hidden by stellar glare and detected indirectly. Astronomers identify them by tracking star wobbles or dips in brightness during planetary transits. NASA’s Kepler mission revealed thousands, with TESS now expanding the search. These discoveries confirm that planetary systems are abundant throughout the …

Asteroids, comets, meteoroids, meteors, and meteorites may seem similar, but each plays a unique role in the Solar System. Asteroids are rocky remnants, comets are icy wanderers, meteors are shooting stars, and meteorites are fragments that survive the plunge to Earth.

In a historic collaboration, scientists created the first comprehensive mammalian brain activity map. The project, led by the International Brain Laboratory, analyzed data from 600,000 cells across 139 mice. Findings revealed that decision-making and memory are spread across the brain, not confined to specific regions as previously believed.

NASA has named Amit Kshatriya as its new Associate Administrator, a role overseeing agency operations and strategy. A 20-year NASA veteran, Kshatriya has led Artemis Moon-to-Mars missions and brings engineering, leadership, and spaceflight expertise. His appointment signals NASA’s renewed focus on Artemis and a bold vision for lunar exploration and future Mars missi…

Astronomers using LIGO-Virgo-KAGRA detected 128 collisions of black holes and neutron stars, including two rare mixed mergers that double previous records. These findings reveal new details of stellar evolution, refine Hubble constant estimates, and test Einstein’s relativity in extreme conditions. The cosmic “graveyard” offers fresh insight into how stars die a…

Scientists at the University of Tokyo have visualized gold nanoclusters in their earliest growth stage and discovered new elongated structures called gold quantum needles. These exhibit remarkable quantum properties, opening possibilities for sharper biomedical imaging and more efficient light-energy conversion in future applications.

In Sept. 2025, NASA and NOAA will launch three spacecraft aboard a Falcon 9 to the Sun–Earth L1 point.

RRI’s PRATUSH—a credit-card-sized computer payload—will detect faint radio signals from hydrogen to study the “Cosmic Dawn”. Designed for deployment on the Moon’s far side, the system offers noise-free, efficient data handling using an SBC and FPGA combo. If successful, it could help determine when the first stars formed and expand our cosmic understanding…

A newly discovered asteroid, 2025 QV5, about the size of a school bus, will safely pass Earth today at a distance of 500,000 miles, roughly twice as far as the moon. NASA’s JPL notes it will not return this close again until September 2125. Scientists are tracking its path to refine orbital predictions and future […]

On October 3, 2025, interstellar comet 3I/ATLAS will pass just 30 million km from Mars — nine times closer than from Earth. ESA’s Mars Express and TGO, along with NASA and China’s orbiters, will attempt to image its coma, analyze gases, and study this rare visitor from beyond the solar system.

Astronomers using JWST and Hubble have discovered JWST’s Quintet, a system of at least five merging galaxies just 800 million years after the Big Bang. This rare find shows how galaxies grew rapidly in the early universe and may explain how some became inactive so soon.
