Melbourne Uni hoping to hoist tiny telescope to look at BIG explosions

A couple of years after it was first conceived, a Melbourne University-led infrared astronomy cubesat proposal called SkyHopper is gathering momentum. Vulture South found itself intrigued by a simple question, which we found time to put to one of the project's founders, astrophysicist Dr Katie Mack: what useful astronomy can …

Cosmology is safe and the Universe is one giant version of the Barbican

Scientists have confirmed that the universe is very likely the same in every direction, showing that the assumption of the universe being isotropic can be safely used in cosmology. The results, published in Physical Review Letters show that there is only a 1 in 121,000 chance that the universe is non-isotropic. On small …

5,000 robots to build 3D map of the universe

Five thousand robots will get busy creating a 3D map of millions of galaxies in 2019. The Dark Energy Spectroscopic Instrument (DESI) has received US Department of Energy (DoE) approval to move from the design phase to construction, which will start next year. That includes building the 5,000 10 cm-long, finger-width robots …

Go catch Pokemon in this, nerds: Our space neighborhood of 1.2m galaxies mapped in 3D

Pics After ten years of work by hundreds of scientists, the Sloan Digital Sky Survey III has produced the most complete map of our nearby universe covering over a million galaxies. "We have spent five years collecting measurements of 1.2 million galaxies over one quarter of the sky to map out the structure of the Universe over a …

Beautiful model to explain the universe to physicists

An international team of cosmologists has made the first step towards creating the most accurate ever model of the universe by simulating Einstein’s field equations, according to recent research published in Physical Review Letters. Computer simulations are vital in cosmology and allow scientists to study and test theories …

Universe's shock rapidly expanding waistline may squash Einstein flat

Pic Cosmologists are scratching their heads after data from the Hubble Space Telescope has shown that the universe is expanding between 5 and 9 per cent faster than first thought. A team led by Nobel Laureate Adam Riess took measurements of 300 visible Type Ia supernovae spread among an assortment of galaxies, as well as around 2, …

Future civilisations won't know how the universe formed

Scientists have estimated that a whopping 92 per cent of "Earth-like" planets have yet to be born, and inhabitants of such worlds in the far-distant future will be "largely clueless as to how or if the universe began and evolved". Those are the conclusions of a study of Hubble Space Telescope and Kepler space observatory data …

MONSTER GALAXY spotted hiding behind IMMENSE BLACK HOLE

Astro-boffins have detailed a "monstrous" galaxy near the edge of the charted universe, and have done so to an unprecedented degree of detail using the Atacama Large Millimetre/submillimetre Array (ALMA), with the assistance of a natural telescopic phenomenon known as a gravitational lens. According to the National Institutes …

In a galaxy far, far, far away ... Farthest ever star system discovered

Pic Astronomers at the Keck Observatory in Hawaii have spotted the farthest galaxy on record – a galaxy 13 billion light-years away that formed 670 million years after the Big Bang. Youngest galaxy yet found I've seen things you people wouldn't believe... (click to enlarge) Several very old galaxies were detected by the …

Got a big day planned in 15 BEELLLION years? You need this clock

The world's most accurate clock has been invented, and is ideal for anyone who doesn't want to be a second late over billions and billions of years. Boffins have improved the accuracy of the best optical atomic clock by a factor of three, so that it will not lose a second in 15 billion years – which is greater than the age of …

PHYSICS APPLECART UPSET as dark energy disappears, Universe slams on brakes

In-the-dark astrophysicists now think there's probably less dark energy knocking about than was previously thought – which may suggest that the universe is expanding at a slower rate. That's at least the latest thinking on the subject to come out of the University of Arizona, whose team of astronomers claimed that their …

TOTAL DARKNESS lasted 550 MILLION years until the first STARS LIT UP

The first stars were formed much later than had been previously thought in the boffinry community, according to new maps of the universe's "ancient light" from the European Space Agency's Planck satellite. Astrophysicists have now calculated that the universe is roughly 13.8 billion years old, based on the light emitted by …

Boffins attempt to prove the UNIVERSE IS JUST A HOLOGRAM

How can we tell from the inside of our Universe if it’s actually real or just a hologram? Boffins at Fermilab have set out to answer this thorny question with a new experiment in the National Accelerator Lab called the Holometer. A Fermilab scientist works on the laser beams at the heart of the Holometer experiment Lasers …

ENTIRE UNIVERSE created in supercomputer. Not THIS universe (probably)

Researchers at MIT and Harvard have created a a giant virtual universe – 350 million light-years squared – which can be used to simulate the real universe's development from 12 million years after the Big Bang to the present day, or around 13 billion years' worth of expansion. Dubbed Illustris, the pocket universe uses over 12 …

SkyMapper turns up oldest star ever found

It's a one-in-60-million search: a group of astronomers has turned up a “second-generation” star, the oldest yet discovered. The star, while given an age of 13.6-plus billion years (more on this later), is quite nearby at just 6,000 light years distant, and is in the Milky Way. What's special about SMSS (SkyMapper Southern …

Hubble boffins: Incredibly old supernova could explain EVERYTHING

NASA's Hubble telescope has spotted the most distant massive star explosion of its kind ever, one which could help boffins understand the very fabric of the universe.
