As I write this, I've just come back from a successful early morning session observing Comet NEOWISE. It's currently glowing at magnitude +3, slightly dimmer than when I first pointed my camera at it a few nights ago. Even without optical aid the comet is an incredible naked-eye sight, visible even in areas of moderate light pollution. Did you manage to spot it? According to the All About Space e-mail inbox and social channels, we've discovered that many of you did, and this issue we've featured your spectacular images as part of our picture gallery on page 6. If you missed our call for submissions, then not to worry – we're still accepting your images of NEOWISE over the next few issues. Details of our social channels can be found below…

comet neowise edition

NEOWISE blazes brightly over O’Brien’s Castle Photographer: Cormac Coyne This photo was taken from Inisheer, the smallest of the Aran Islands that sits in the middle of Galway Bay on the west coast of Ireland. Just after midnight on 11 July, photographer Cormac Coyne climbed up to one of the highest points on Inisheer that overlooks O’Brien’s Castle. “When I was setting up above the castle, noctilucent clouds were just beginning to form,” he said. To capture NEOWISE, Coyne used a Canon EOS, coupled with a Canon 70-200mm f/2.8 Mark 3 lens. Despite being a naked-eye comet, Coyne also observed NEOWISE through binoculars. “I took the photos into Adobe Camera Raw, processed them and then saved them as a JPEG file,” he added.

‘partial supernova’ blasts white dwarf star across the milky way

A strange white dwarf star hurtling through the Milky Way may be the survivor of a ‘partial supernova’, a new study finds. White dwarfs are the cool, dim Earth-sized cores of dead stars that are left behind after average-sized 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 the Milky Way. Scientists zeroed in on the white dwarf SDSS J1240+6710, located about 1,430 light years from Earth. Discovered in 2015, prior work found this white dwarf had an unusual atmosphere that seemed to possess neither hydrogen or helium, but instead was composed of a weird mix of oxygen, neon, magnesium and silicon. The Hubble Space Telescope was used to take a…

strange ancient ‘failed stars’ found by citizen scientists

Citizen scientists recently helped direct astronomers to a pair of objects that straddle the line between planets and stars. These newly spotted substellar objects are brown dwarfs, which share many elements in common with stars. However, unlike stars these gaseous bodies don’t have enough mass to start nuclear fusion in their core, so they resemble planets more than stars. These newfound brown dwarfs have very unusual compositions. They are the most planet-like brown dwarfs to be observed in the Milky Way’s oldest populations of stars. They also might help researchers learn more about planets outside the Solar System. The citizen scientists who spotted both objects were part of the ongoing NASA-funded Backyard Worlds: Planet 9 project. They were looking through spacecraft data from NASA’s WISE and NEOWISE missions; both missions are chapters…

gigantic structure stretching 1.37 billion light years across discovered

Spectacular 3D maps of the universe have revealed one of the biggest cosmic structures ever found – an almost-inconceivable wall stretching 1.37 billion light years across that contains hundreds of thousands of galaxies. The South Pole Wall, as it’s been dubbed, has been hiding in plain sight, remaining undetected until now because large parts of it sit half a billion light years away behind the bright Milky Way galaxy. The South Pole Wall rivals in size the Sloan Great Wall, the sixth-largest cosmic structure discovered. One light year is roughly nine trillion kilometres (six trillion miles), so this cosmic structure is mind-bendingly humongous. Astronomers have long noticed that galaxies are not scattered randomly throughout the universe, but rather clump together in what’s known as the cosmic web, enormous strands of hydrogen…
