NASA’s PUNCH Watches Comet Lemmon Respond to the Sun’s Powerful Influence

NASA’s PUNCH mission has captured striking views of Comet Lemmon as it passed close to the Sun in late 2025. The observations show how solar wind and eruptions reshape a comet’s tail, sometimes causing it to break and regrow. The images provide valuable insight into how solar activity affects objects across the inner solar system.

There’s a new space race – will the billionaires win?

The commercialisation of the cosmos is already underway, and our current laws aren’t fit for purpose

If there is one thing we can rely on in this world, it is human hubris, and space and astronomy are no exception.

The ancients believed that everything revolved around Earth. In the 16th century, Copernicus and his peers overturned that view with the heliocentric model. Since then, telescopes and spacecraft have revealed just how insignificant we are. There are hundreds of billions of stars in our galaxy, the Milky Way, each star a sun like ours, many with planets orbiting them. In 1995, the Hubble space telescope captured its first deep-field image: this showed us that there are hundreds of billions of galaxies in our known universe, huge wheeling collections of stars dispersed through space.

Electricity-Driven Nitrogen Insertion Opens a Sustainable Path to Drug-Ready Heterocycles

Scientists at the National University of Singapore have developed an electricity-driven method to insert nitrogen into stable carbon rings, enabling greener synthesis of valuable heterocycles. Published in Nature Synthesis, the approach avoids harsh chemicals, reduces waste, and allows access to key drug-ready molecular frameworks under mild conditions.

Astronomers Observe Black Hole Twisting Spacetime for the First Time, Confirming Einstein’s Theory

Astronomers have directly observed a black hole twisting spacetime for the first time, confirming Einstein’s long-standing prediction. The effect was detected during a violent stellar destruction event, where repeating X-ray and radio signals revealed a slow cosmic wobble. The discovery provides new insight into black hole spin, jets, and extreme gravity.

Hubble Captures Rare Collision in Nearby Planetary System, Revealing Violent Planet Formation

Astronomers using NASA’s Hubble Space Telescope have witnessed rare collisions between rocky bodies in the Fomalhaut system. The glowing debris clouds created by these impacts offer a unique glimpse into how planets form and highlight challenges in identifying true exoplanets.

Scientists Rule Out Elusive Sterile Neutrino After 10-Year Hunt, Shaking Particle Physics

After ten years of experiments, physicists found no evidence for the sterile neutrino, once thought to explain unusual neutrino behaviour. The MicroBooNE experiment at Fermilab analysed neutrinos from two beams and ruled out the particle with 95% certainty. The findings narrow the search for new physics and inform future experiments like DUNE.

Starlink Satellite Breaks Apart in Orbit, Begins Uncontrolled Fall Toward Earth After SpaceX Anomaly

A SpaceX Starlink satellite is tumbling toward Earth after an orbital anomaly caused partial breakup and loss of contact. The company says the spacecraft will safely burn up during reentry, while the incident highlights increasing space safety concerns as satellite numbers continue to grow rapidly.

NASA’s Perseverance Rover Poised for Years of Exploration Across Jezero Crater

NASA’s Perseverance rover, in excellent condition, is ready for long-term Mars exploration. Using autonomous driving, it has travelled nearly 25 miles, studied olivine-rich rocks, and collected samples revealing potential signs of past microbial life. The rover now heads to Lac de Charmes for further scientific investigation, promising years of discoveries about Mar...
