At some point, statistically speaking, a large asteroid will impact Earth. Whether that’s tomorrow, in ten years, or a problem for our ancestors, ESA is getting prepared.

As part of the world’s first test of asteroid deflection, ESA’s Hera mission will perform a detailed post-impact survey of Dimorphos – the 160-metre asteroid struck, and successfully deflected, by NASA’s DART spacecraft.

Hera will soon study the aftermath. Launching in October 2024, Hera will turn this grand-scale experiment into a well-understood and hopefully repeatable planetary defence technique.

But before Hera and its two CubeSats fly, they’re rigorously tested at ESA’s ESTEC test

Earth planning date: Wednesday, October 18, 2023: The target 'Sequoia' has been successfully drilled! The image today is one of my favourites - the shadow of the rover mast, and the perfectly drilled target in the background... it doesn't get much better than that! Curiosity stays in place for a little while longer for CheMin analysis of the drilled material, and no drive meant we had more power

Astronomers at ARC are one step closer to understanding an enduring solar mystery by capturing the most detailed representations to date of the magnetic field of the 'quiet Sun' - and discovering something unexpected in the process. The researchers from the Astrophysics Research Centre (ARC) at the School of Mathematics and Physics at Queen's have collected groundbreaking data with the US

In a paper published in Science, a global team led by Macquarie University's Dr Stuart Ryder and Swinburne University of Technology's Associate Professor Ryan Shannon, report on their discovery of the most ancient and distant fast radio burst located to date, about eight billion years old. The discovery smashes the team's previous record by 50 per cent. It confirms that fast radio bursts (

NASA recently built and tested an additively-manufactured - or 3D printed - rocket engine nozzle made of aluminum, making it lighter than conventional nozzles and setting the course for deep space flights that can carry more payloads. Under the agency's Announcement of Collaborative Opportunity, engineers from NASA's Marshall Space Flight Center in Huntsville, Alabama, partnered with Eleme

NASA's Lucy spacecraft is preparing for its first close-up look at an asteroid. On Nov. 1, it will fly by asteroid Dinkinesh and test its instruments in preparation for visits in the next decade to multiple Trojan asteroids that circle the Sun in the same orbit as Jupiter. Dinkinesh, less than half a mile, or 1 kilometer, wide, circles the Sun in the main belt of asteroids located between

Heart disease is the leading cause of death globally, and once cardiovascular tissue is damaged, there's no means of restoring its function. But it's possible damaged tissue could be regenerated via stem cell therapies. To that end, a team of scientists took their research to new heights by leveraging the International Space Station (ISS) National Laboratory to study microgravity's effects on he

Southampton UK (SPX) Oct 20, 2023
Researchers from the University of Southampton, together with colleagues from the universities of Cambridge and Barcelona, have shown it's theoretically possible for black holes to exist in perfectly balanced pairs - held in equilibrium by a cosmological force - mimicking a single black hole. Black holes are massive astronomical objects that have such a strong gravitational pull that nothi

An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observ
