welcome

Do you remember where you were and what you were doing when the Hubble Space Telescope launched? After doing a quick survey around the office, not many can. However – quite unsurprisingly – what they do recall is the incredible set of discoveries, images and turning points that have not only made some corners of the universe much more visible, but brought us to the 30th anniversary of one of humankind's greatest achievements. It truly is a massive milestone – and we've made sure to celebrate it. This month, whether you're a subscriber to the magazine or hunt for us in your local newsagent or supermarket, you'll be able to get hold of 30 exclusive All About Space covers, each featuring one of Hubble's very best images. From Jupiter to the…

launch pad

Airglow lights up the Chilean desert Airglow is a fantastic phenomenon that only graces a select number of regions across the entire world. The Atacama Desert in Chile is one of these locations, as it is as far from light pollution as possible and exhibits very few cloudy nights. It is this lack of artificial light and interference that brings a glow to the air. Within Earth’s atmosphere, molecules are constantly colliding and emitting radiation over a range of wavelengths and colours. The mechanism is responsible for the majestic multicoloured sky over the dry Atacama Desert, visible in this image. The start of Expedition 62 At the International Space Station’s changing of the guard, a new expedition dawns. Expedition 62 is now the focus of attention: the mission patch for the venture is…

ripples in space-time could explain the mystery of why the universe exists

New research may help answer one of the universe’s biggest mysteries: why is there more matter than antimatter? That answer in turn could explain why everything from atoms to black holes exist. Billions of years ago, almost immediately after the Big Bang, cosmic inflation stretched the tiny seed of our universe and transformed energy into matter. Physicists think inflation initially created the same amount of matter and antimatter, which annihilate each other on contact. But then something happened that tipped the scales in favour of matter, allowing everything we can see and touch to come into existence – a new study suggests that the explanation is hidden in very slight ripples in space-time. “If you just start off with an equal component of matter and antimatter, you would just end up with…

the early earth had water, but no continents

What did Earth look like 3.2 billion years ago? New evidence suggests the planet was covered by a vast ocean and had no continents. These appeared later as plate tectonics thrust enormous, rocky land masses upward to breach the sea surface. Scientists found clues about this ancient water world preserved in a chunk of ancient seafloor, now located in the outback of northwestern Australia. Around 4.5 billion years ago, high-speed collisions between dust and space rocks formed the beginnings of our planet: a bubbling, molten sphere of magma that was thousands of miles deep. Earth then cooled as it spun; eventually, after 1,000 to 1 million years, the cooling magma formed the first mineral crystals in Earth’s crust. Earth’s first water may have been carried here by ice-rich comets from outside our…

oddball giant white dwarf may have formed in crash between smaller stars

A giant white dwarf star may be the offspring of a collision between two other white dwarfs, which may help shed light on how massive these stars must be in order to explode in a supernova. White dwarfs are the dim, fading cores of dead stars that are left behind after average-size stars have exhausted their fuel and shed their outer layers. Our Sun will one day become a white dwarf, as will more than 90 per cent of the stars in our galaxy. Scientists led by Mark Hollands, an astrophysicist at the University of Warwick, England, studied a white dwarf known as WDJ0551+4135, which is located about 150 light years from Earth. The European Space Agency’s Gaia telescope suggested that this object might be an exceptionally massive white dwarf. To…
