Hubble spies most distant comet zipping through Solar System

The Hubble Space Telescope has snapped a picture of the farthest-away inbound comet, at a whopping 1.5 billion miles from Earth. It's a strange find. The comet – codenamed C/2017 K2 PANSTARRS, or K2 for short – has already become active. It is developing a vast 80,000-mile-wide halo of dust as its surface sublimes, despite …

Boffins grudgingly admit they may have found an exomoon

After Twitter-leaks, a trio of exoplanet-hunters have decided to go public with observations they reckoned weren't quite up to broadcast-quality but which is rather significant: the first possible detection of a moon orbiting an exoplanet. It's hard enough to reliably spot exoplanets given that we do so by observing tiny …

Two hot Jupiters around two similar stars orbiting at similar distances look similar, right? WRONG

WASP-67 b and HAT-P-38 b are two far-flung exoplanets orbiting near-identical stars at similar distances. Their size and temperatures are also pretty close. So, naturally, astronomers thought that their atmospheres wouldn't be too far apart. They were wrong. "We don't see what we're expecting," said Giovanni Bruno, a …

H0LiCOW! Hubble's constant update paves way for 'new physics'

The latest measurement of the Hubble constant is higher than previous values, prompting scientists to believe there may be “new physics” beyond the standard model of cosmology yet to be discovered. Named after the physicist Edwin Hubble, the Hubble constant is a measurement of how fast the cosmos is expanding. It provides a …

Major maser microwaves Hubble

The name's boring but the science isn't: an entire galaxy spied by the Hubble Space Telescope is acting as a microwave-emitting laser, or maser. Think of the process going on here: in a laser, molecules in a crystal are stimulated to add energy to electrons, and when they shed that energy, they emit coherent light (or, at …

New Brit Hubble analysis finds 2,000 billion galaxies, 10x previous count

Douglas Adams was right. Space is really big. New analysis of data from the Hubble Space Telescope and other observatories suggests there are ten times more galaxies out there than previously thought. The theory is advanced in a paper (PDF) titled “The Evolution of Galaxy Number Density at Z < 8 and its implications” that …

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, …

Hubble spies on Europa shooting alien juice from its southern pole

Pics and video Images from the Hubble Space Telescope of Jupiter's most intriguing moon, Europa, appear to show plumes of water being ejected from the surface into space. The telescope took a series of ten shots of Europa over 15 months in the last two years as it passed in front of Jupiter, using the reflected light from the gas giant to …

NASA image of the covert black hole

Mystery black hole hides by curbing its appetite

A well-known radio source has turned out not to be the galaxy it's been classified as for 20 years, but a surprisingly quiet black hole. The discovery is causing a bit of buzz among astrophysicists because it suggests there could be thousands or millions more “covert” black holes out there waiting to be discovered. It took …

Hubble spies rare cosmic tadpole galaxy

The Hubble telescope has captured images of a rare tadpole galaxy glittering with bursts of star formation, swimming in the black pond of space. In a collaboration between NASA and the European Space Agency, the telescope was used to take high-resolution images of cosmic objects across a range of wavelengths. Hubble has taken …

Supermassive black hole devours star and becomes X-ray flashlight

Astronomers have identified a sleeping black hole that sprung back to life – after trapping a nearby star to be later consumed – due to the curved space-time around it firing X-rays into space, according to research published today in Nature. Black holes have a strong gravitational pull on any nearby objects, and if anything …

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, …

Hubble spies supermassive black hole in surprising spot

Scientists using the Hubble Space Telescope have spotted a huge black hole with 17 billion times the mass of our sun residing in an otherwise nearly empty backwater of the universe. Supermassive black holes are typically found at the center of busy crowded galaxies, but this example was found in the sparsely populated …

Good eye, Hubble! Space 'scope spots furthest-ever object

The Hubble Space Telescope may be old enough to rent a car, but the aging orbital lab is still making new discoveries, the latest being the furthest-recorded object ever spotted. Scientists with the European Space Agency (ESA) said that they have detected the light from GN-z11, which had been an infant galaxy when its light …

Hubble finds lonely 'void galaxy' floating in cosmic nothingness

“In a galaxy far, far away” you don't see much, it seems. The image at the top (here for readers on mobile devices) is one of the latest shots retrieved from Hubble, and the galaxy that's front-and-centre is one of the loneliest ever snapped. It even has to suffer a dull, prosaic name: MCG+01-02-015. In spite of its apparent …

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 …

Astroboffins snap BREATHTAKING, WISPY Veil Nebula supernova debris

Vid NASA has released spectacular new photos of a massive star's remnants, dubbed Veil Nebula, following an ancient supernova explosion. Boffins captured the images with the Hubble Space Telescope to show off the debris of the gigantic star, which exploded roughly 8,000 years ago when the supernova that created the Veil Nebula …

Astroboffins EYEBALL 13 BEELLION-year-old galaxy far, far, farthest away from Earth

Scientists reckon they have detected a galaxy that is more than 13 billion years old. It's understood to be the most distant galaxy ever observed by boffins, who revealed their findings in the latest issue of Astrophysical Journal Letters. The 13.2 billion-year-old galaxy has been dubbed EGS8p7. It was tagged as a candidate …
