Sending an object to another star is still the stuff of science fiction. But some concrete missions could get us at least part way there. These “interstellar precursor missions” include a trip to the Solar Gravitational Lens point at 550 AU from the Sun – farther than any artificial object has ever been, including Voyager. To get there, we’ll need plenty of new technologies, and a recent paper presented at the 75th International Astronautical Congress in Milan this month looks at one of those potential technologies – electric propulsion systems, otherwise known as ion drives. 

Neutron stars and black holes are the remnants of dead stars. They typically form as part of a supernova explosion, where the outer layers of an old star are violently cast off while the core of the star collapses to form the remnant. This violent origin can have significant consequences for both the remnant and the surrounding environment.

It was 1969 that humans first set foot on the Moon. Now, over 50 years later we are setting sights on building lunar bases. The ability to complete that goal is dependent on either transporting significant amounts of material to the Moon to construct bases or somehow utilising raw lunar materials. A team of Chinese researchers have developed a technique to create bricks from material that is very similar to the soil found on the Moon. The hope is that the lunar soil can in the future, be used to build bricks on the Moon.

Everybody knows that for life to thrive on any world, you need water, warmth, and something to eat. It’s like a habitability mantra. But, what other factors affect habitability? What if you relaxed the conditions conducive to life? Would it still exist? If so, what would it be?

One of the many threats facing space travellers and indeed our own planet is that of Solar Storms. At their most minor they can grant polar latitudes with a gentle auroral display but at their most extreme they can pose a threat to technology in space, communications and even our atmosphere. Now a team of researchers have found that extreme space weather can leave its mark in tree rings, leaving evidence that can help guard against future severe events. 

This stunning image of a star cluster in the Small Magellanic Cloud (SMC) is more than just a pretty picture. It’s part of a scientific effort to understand star formation in an environment different from ours. The young star cluster is called NGC 602, and it’s very young, only about 2 or 3 million years old.
