Zinnia flowers are starting to grow in the International Space Station's Veggie facility as part of the VEG-01 investigation. Veggie provides lighting and nutrient supply for plants in the form of a low-cost growth chamber and planting "pillows” to provide nutrients for the root system. These plants appear larger than their ground-based counterparts and scientists expect buds to form on the larger plants soon.
Recently analyzed data from NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has revealed water locked inside the clays that make up its scientific target, the asteroid Bennu.
It’s embarrassing, but astrophysicists are the first to admit it. Our best theoretical model can only explain 5% of the universe. The remaining 95% is famously made up almost entirely of invisible, unknown material dubbed dark energy and dark matter. So even though there are a billion trillion stars in the observable universe, they are actually extremely rare.
Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive, and relatively expensive to run.
Many people wonder why they’re not losing weight when they follow a strict diet and exercise routine.
'Oumuamua, meaning scout or messenger in Hawaiian, is the name given to the first detected interstellar object to visit our Solar System. On discovery last year, 'Oumuamua was classified as a comet, but this was later withdrawn when no evidence for cometary activity was detected.
The potential discovery of a planet orbiting Barnard’s Star – the second closest stellar system to the Sun – was announced by researchers today in Nature.
In the past thirty years, the number of planets discovered beyond our Solar System has grown exponentially. Unfortunately, due to the limitations of our technology, the vast majority of these exoplanets have been discovered by indirect means, often by detecting the transits of planets in front of their stars (the Transit Method) or by the gravitational influence they exert on their star (the Radial Velocity Method)
Why is my awareness here, while yours is over there? Why is the universe split in two for each of us, into a subject and an infinity of objects? How is each of us our own center of experience, receiving information about the rest of the world out there? Why are some things conscious and others apparently not? Is a rat conscious? A gnat? A bacterium?
Imagine trying to map out your home town using only information you could gather from your window. Even with a pair of binoculars you’d find it a difficult task. Mapping out our own galaxy, the Milky Way, is a similarly daunting mission. Unlike other galaxies that we can view from a distance, we sit inside the Milky Way – around 26,000 light years from its center. This means that when we try to look at the opposite side of the galaxy, much of our view is blocked by the stars and dust in between.
The human desire to create ever bigger and more impressive structures is insatiable. The pyramids of Ancient Egypt, the Great Wall of China and the Burj Khalifa in Dubai – now the tallest edifice in the world at over 828 metres (2,722 ft) – are a consequence of pushing engineering to its limits. But huge buildings aren’t just monuments to human ambition: they might also hold the key to humanity’s progress in the space-faring age.
