With his love of science fiction and photography, it seems that Ian Inverarity has always been destined to become involved with astrophotography. Key points: A mechanical engineer from Adelaide has won this year’s David Malin astrophotography award Amateur astrophotography is booming as a hobby as technology becomes more advanced and affordable This year’s competition entered the smartphone category for the first time Mechanical engineers have been capturing the wonders of the night sky for several years now, traveling to regional South Australia in search of the perfect shot. He said the addictive pursuit took him to Gawler, north of Adelaide, about once a month. And many nights and hours in darkness have paid off, with his photo of an old gum tree at Gawler shrouded in mist before the Milky Way picks up this year’s David Malin astrophotography award in New South Wales. “It’s relatively unusual. Out of the seven years or so I’ve been going there, I’ve only encountered fog at night,” I

Have you heard of the LU Camelopardalis, QZ Serpentis, V1007 Herculis, and BK Lyncis? No, they weren’t in the boy band in ancient Rome. They are Cataclysmic Variables, binary stars so close together that one star takes matter from its sibling. This causes the pairs to vary greatly in brightness. Could a planet exist in this chaotic environment? Can we see them? A new study says yes to both. Cataclysmic Variables (CVs) experienced a large increase in brightness. All stars vary in brightness to some degree, even our own sun. But the CV increase in brightness is much more pronounced than in stars like our Sun, and it happens on an irregular basis There are different types of catastrophic variables: classic nova, dwarf nova, multiple supernova, and others. All types share the same basic mechanics. A pair of stars orbit each other closely, and one star is larger than the other. The more massive ones are called primary stars, and draw gas from lower-mass stars, which astronomers ca

NASA has released more images of the galaxy thousands of light years away, captured by their James Webb Space Telescope. And that raises a lot of questions: Will we discover new planets? What would you see from inside one of these galaxies? How big are these pictures really? In an effort to unravel the latest discoveries in our cosmos, we ask you to ask the experts your burning questions. Here’s a bit of what we learned (you can follow the full Q&A here): These galaxies don’t look like this anymore… and may not even exist The first images were released from the James Webb Space Telescope. ( Provided: NASA ) “If the images are billions of years old, can you presume that some of the ‘bodies’ we see don’t exist today? They may look like lots of stars but they are images of the past, if you know what I mean. What’s really there now.” – Nigel Astrophysicist Robin Cook from the University of Western Australia said “absolutely”. “As astronomers, we actually act as great historians – t

The heart of the Milky Way appears to be a hotspot for molecules that combine to form RNA. A new survey of the thick molecular cloud that shrouds the galactic center has revealed the presence of various nitriles – organic molecules that are often toxic in isolation, but are also molecular building blocks essential for life. The increase in prebiotic molecules (molecules involved in the emergence of life) identified at the center of galaxies, particularly those associated with RNA, has implications for our understanding of how life emerged in the Universe – and how it happened on Earth. “Here we show that the chemistry occurring in the interstellar medium is able to efficiently form some of the nitriles, which are key molecular precursors of the ‘RNA World’ scenario,” explains astrobiologist Víctor Rivilla of the Spanish National Research Council and National Institutes. Aerospace Technology in Spain. Exactly how life arose on Earth is a mystery that basic scientists are eager to achie
