There’s a hole in the universe. Granted, it’s not a physical hole that leads us to a place that’s outside the cosmos – it’s a void where there isn’t a great deal going on. And that’s because there’s supposedly nothing there: no matter, no stars, no galaxies, no black holes. Zilch. So what’s going on inside it, and how did it get there? That’s one discussion I had with All About Space’s Art Editor, Jonathan Wells, and the answer is quite illuminating to say the least. Turn to page 14 for everything you need to know (and the current research) into one of the weirdest places in the universe. Also in this issue, we’ve created a quick bluffer’s guide to understanding the fundamental properties of nature at a subatomic level, the ambitious…

YOUR FIRST CONTACT WITH THE UNIVERSE 15 FEBRUARY 2021 Baby star’s tantrum These wispy jets ejected across space are one of the rarer sights in the night sky, known as Herbig-Haro objects. This image captures two such objects, catalogued as HH 46 and HH 47, in the constellation of Vela (the Sails) 1,400 light years away. These emissions are ejected from newly born stars and are rapidly expelled across space at speeds of over 150 kilometres (93 miles) per second. The jets then collide with the surrounding gas, creating the bright shock waves, which have been imaged here by Hubble. 22 FEBRUARY 2021 Evil eye The Hubble Space Telescope has captured this striking image of NGC 4826, a spiral galaxy often referred to as the ‘Evil Eye’ or ‘Black Eye’ Galaxy due to the dark cloud…

cosmologists create 4,000 virtual universes to solve big bang mystery

YOUR FIRST CONTACT WITH THE UNIVERSE Cosmologists are pressing rewind on the first instant after the Big Bang by simulating 4,000 versions of the universe on a massive supercomputer. The goal is to paint a picture of the immediate aftermath of the Big Bang, when the observable universe suddenly expanded 1 trillion trillion times in size in the tiniest sliver of a microsecond. By applying the method used for the simulations to real observations of today’s universe, researchers hope to arrive at an accurate understanding of what this inflationary period looked like. “We are trying to do something like guessing a baby photo of our universe from the latest picture,” said lead researcher Masato Shirasaki, a cosmologist at the National Astronomical Observatory of Japan (NAOJ). Today’s universe shows variations in density, with…

european space agency announces call for ‘parastronauts’ with disabilities

The European Space Agency (ESA) is diversifying its astronaut pool with its first call for astronauts open to candidates with physical disabilities. In this call for new astronauts, the agency’s first recruitment drive in over a decade, the ESA announced that it plans to accept four to six career astronauts, who will be permanent ESA staff, and about 20 ‘reserve astronauts’, who could fly for shorter missions to destinations like the International Space Station. As part of this call for astronaut applicants, ESA director general Jan Wörner revealed that the agency is aiming to bring its first ‘parastronaut,’ or astronaut with physical disabilities, on board. “The ESA is ready to invest in defining the necessary adaptations of space hardware in an effort to enable these otherwise excellently qualified professionals to serve…

company plans to start building private voyager space station with artificial gravity in 2025

Orbital Assembly Corporation (OAC) recently unveiled new details about its ambitious Voyager Station, projected to be the first commercial space station operating with artificial gravity. OAC, a manufacturing firm centred on the colonisation of space, discussed Voyager during a press junket in January. The virtual event served as an update for interested investors, marketing partners and enthusiastic holidaymakers hoping to someday book a room aboard the rotating Voyager Station. During the event, the company revealed its schedule for the next chapter of human space exploration. Its team of skilled NASA veterans, pilots, engineers and architects intends to assemble a ‘space hotel’ in low-Earth orbit that rotates fast enough to generate artificial gravity for holidaymakers, scientists, astronauts and anyone else who wants to experience off-Earth living. Voyager Station is patterned after concepts imagined…

‘ghostly’ neutrino from star-shredding black hole reveals cosmic particle accelerator

YOUR FIRST CONTACT WITH THE UNIVERSE A ghostly particle that smashed into Antarctica in 2019 has been traced back to a black hole tearing apart a star while acting like a giant cosmic particle accelerator. Scientists investigated the extremely high-energy neutrino they spotted on 1 October 2019 using the IceCube Neutrino Observatory. “It smashed into the Antarctic ice with a remarkable energy of more than 100 teraelectronvolts,” said researcher Anna Franckowiak. “For comparison, that’s at least ten times the maximum particle energy that can be achieved in the world’s most powerful particle accelerator, the Large Hadron Collider.” To discover the origins of such a powerful neutrino, the scientists traced its path through space. They found that it likely came from the galaxy designated 2MASX J20570298+1412165 in the constellation Delphinus, the Dolphin, and…
