Astroboffins find most distant source of oxygen in the universe

Astrophysicists have detected the most distant signal of oxygen yet, in a galaxy more than 13 billion light years away, when the universe was less than 4 per cent of its current age. A paper published in Nature shows that the galaxy, MACS1149-JD1, was surprisingly mature enough to be forming abundant amounts oxygen at such a …

The Sun will blow up into a huge, glowing bubble of gas during its death

The Sun will shed a large chunk of its mass to turn into a planetary nebula, a gigantic globe of luminous gas, as it nears the end of its life cycle. Low mass stars like the Sun will become red giants and then white dwarves when they die. Now, a paper published in Nature Astronomy predicts that in between those stages, the Sun …

It's ALIIIIIVE: Boffins detect slow-moving zombie star

The European Space Agency's INTEGRAL space observatory has captured an unusual piece of stellar voodoo: the moment when a dead star was brought back to life by a nearby red giant. The slowly rotating core of the zombie star was revived by x-ray flares from its engorged neighbour, giving rise to a high energy emission from the …

Boffins: Sun's red dwarf neighbour is looking a little thick around the middle

New research suggests that a dust belt may be circling the closest star to the Sun, a red dwarf named Proxima Centauri. Guillem Anglada at the Institute of Astrophysics of Andalucía in Granada, Spain, led the work (PDF), which was accepted for publication last week in Astrophysical Journal Letters. He told The Register a belt …

Astroboffins spot a fat 'monster' ALIEN planet terrorizing tiny dwarf

Pic Scientists have discovered a new “monster” alien world that challenges today's theories about planet formation due to its sheer size. The giant, known as NGTS-1b, is 600 light years away and is the biggest planet compared to the size of its parent star NGTS-1 ever found. NGTS-1b is a hot Jupiter, a rare class of exoplanet. …

Astroboffins spot tiniest star yet – we guess you could call it... small fry

The tiniest star, similar in size to Saturn, has been discovered as part of an eclipsing binary system by a group of astronomers. Codenamed EBLM J0555-57Ab, researchers believe the star is teetering on the edge of how small a star can possibly be. It has a mass (0.081M☉) and radius (0.084R☉) less than a tenth of our Sun’s mass …

You wait ages for a sun, then two come along at once: All stars have twins, say astroboffins

Nearly all stars, including our Sun, are born from hot, dense molecular clouds and come in pairs, according to a paper to be published in the Monthly Notices of the Royal Astronomical Society. Binary star systems are common in space. It was estimated that up to 80 per cent of massive, bright O‑type and B‑type stars are locked …

PACK YOUR BAGS! Boffins spot Earth-size planet most likeliest yet to harbor alien life

Scientists have spotted a planet slightly larger than Earth orbiting a distant star that looks to be the best contender yet for hosting life as we know it. In a paper in the journal Nature, published today, the team lead by Jason Dittmann of the Harvard-Smithsonian Center for Astrophysics described LHS 1140, a rocky exoplanet …

Pulsating white dwarf described as a 'dynamo' found, no, not in the back pages, 380 LY away

Fifty years after pulsars were discovered, scientists in the UK and South Africa have spotted the first white dwarf that mimics the emissions of a neutron star. Collapsed star AR Scorpii (AR Sco), spotted 380 light years away by a team from the University of Warwick and the South African Astronomical Observatory, is about the …

Really weird quantum phenomenon spied lurking near neutron star

Pic A neutron star may have led astronomers to find signs of a strange quantum phenomenon in vacuum space that was predicted more than eighty years ago. In quantum electrodynamics (QED), space isn’t really empty. Virtual particle and antiparticle pairs continually pop up and disappear. In the presence of very strong magnetic …

Hubble telescope spies massive 'cannonballs' of fire from dying star

NASA's Hubble Space Telescope has detected massive, super-hot "cannonballs" shooting from a dying star, which has left scientists puzzled over the source of these giant globs of gas. The fireballs are twice as big as Mars and are travelling so fast, it would only take 30 minutes for them to travel from Earth to the moon, …

Science non-fiction: Newly spotted alien world bathes in glow of three stars

A newly discovered planet is wedged in-between three stars and experiences triple sunrises and sunsets every day, according to new research published in Science. The planet, HD 131399Ab, is 340 light years away from Earth and can be found in Centaurus constellation – one of the largest constellations in the sky. "HD 131399Ab …

Sneaky brown dwarf gives us a bright flash and astroboffins are confused

Astronomers have discovered a brown dwarf star emitting flashes of light brighter than the Sun – even though it's not supposed to be able to do that. Brown dwarves are also known as “failed stars” since they do not generate enough energy to support hydrogen fusion – a process that sustains a star’s brightness over millions of …

SPLAT! STAR THWACKED, GUTS flung into space at 15 per cent of LIGHTSPEED

In perhaps the most violent punch that has ever been witnessed by humanity, a speeding pulsar has smashed right through a disk of matter bulging from the middle of a hefty star and blown a massive chunk of it guts into interstellar space at a significant fraction of light speed. That's according to top space boffins peering …

Version 0.1 super-stars built the universe – and they lived all the way over there, boffins point

Pic Astronomers have recorded the brightest galaxy yet seen in the universe. It was formed 800 million years after the Big Bang, and has evidence of an until-now theoretical type of star. The galaxy, dubbed Cosmos Redshift 7 aka CR7, is three times brighter than anything astronomers have seen so far, but the distances involved …

SLOPPY STELLAR CANNIBAL star is a NASTY 1, astroboffins squeal

Scientists have observed odd features present in a supermassive star in our galaxy that they have somewhat appropriately dubbed Nasty 1. It was in fact first clocked decades ago, when astroboffins believed they had found a Wolf-Rayet star – a rare type of hot, cosmic beast that grows huge in its old age as it starts to run out …

Rings around distant planet

Excitement in boffinry circles as GIGANTIC ALIEN RING BLOTS OUT SUN

Pics The first planetary ring system outside of our Solar System has been spotted and it's massive – in fact, it's 120 million kilometers in diameter. "This planet is much larger than Jupiter or Saturn, and its ring system is roughly 200 times larger than Saturn's rings are today," said Eric Mamajek, professor of physics and …

HOT YOUNG STAR about to GIVE BIRTH, long range images show

Boffins have been left in shock after glimpsing the interstellar equivalent of a teenage pregnancy. Researchers used the Atacama Large Millimeter Array (ALMA) to snap super-high resolution images of a young star in the process of giving birth to a series of planets. The team who took the candid shot were shocked to see such …
