Australian researchers using a CSIRO radio telescope in Western Australia have nearly doubled the known number of 'fast radio bursts'— powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected. Their findings were reported today in the journal Nature.

The Voyager 2 probe, now 17.7 billion kilometres (11 billion miles) from Earth, is detecting an increase in cosmic rays from outside the solar system, an indication the long-lived spacecraft is nearing the outer limits of the Sun’s influence and is about to sail into interstellar space. For the past 11 years, Voyager 2 has been plowing through the outer reaches of the heliosphere, a vast protective bubble around the solar system shaped by the Sun’s magnetic field and populated by electrically charged particles blown away in the solar wind.

Astronomers believe they have discovered the first known moon beyond our solar system, in orbit around a gigantic planet 8,000 light years away. The so-called exomoon, which is estimated to be the size of Neptune, would also be the biggest known moon, far exceeding anything known to exist in our own solar system. The team behind the apparent discovery said it needed further confirmation but that they had failed to find any other convincing explanation for their data.

An extremely distant dwarf planet, named The Goblin, has been discovered in observations that are redefining the outer reaches of the solar system. Astronomers made the discovery while hunting for a hypothetical massive planet, known as Planet Nine, that is suspected to be in orbit far beyond Pluto in a mysterious region known as the Oort Cloud. Planet Nine has not yet been seen directly, but The Goblin appears to be under the gravitational influence of a giant unseen object, adding to astronomers’ certainty that it is out there.

There's something mysterious coming up from the frozen ground in Antarctica, and it could break physics as we know it. Physicists don't know what it is exactly. But they do know it's some sort of cosmic ray — a high-energy particle that's blasted its way through space, into the Earth, and back out again. But the particles physicists know about — the collection of particles that make up what scientists call the Standard Model (SM) of particle physics — shouldn't be able to do that.

Two Japanese robots have sent back their first video images from the surface of a moving asteroid as part of an unprecedented mission aimed at shedding light on the origins of the solar system. The Japan Aerospace Exploration Agency (Jaxa) released the 15-frame clip along with new photographs days after the unmanned spacecraft Hayabusa2 deployed the rovers on to the asteroid’s surface after a three-and-a-half year journey.

NASA has ventured every which way across the solar system, but a change of direction closer to home could be its most audacious move since the moon landings. In the next decade, a typical mission could go something like this: NASA astronauts board a SpaceX Big Falcon Rocket (BFR) along with commercial astronauts and a few wealthy tourists. The rocket stops at the new space hotel circling the globe to drop off the visitors and the NASA astronauts spend a few hours there filming an advertisement and lending their endorsement to the privately owned "microgravity resort."

“Over the past few days, engineers here at JPL have been working to address an issue on Curiosity that is preventing it from sending much of the science and engineering data stored in its memory,” the Curiosity team explains. “The rover remains in its normal mode and is otherwise healthy and responsive.” The rover isn’t totally silent, however, and is still relaying certain status information, just not the science data it has stored locally. This strange set of circumstances is leaving Curiosity’s engineers scratching their heads.

The American space agency has launched a laser into orbit to measure the condition of Earth's ice cover. The satellite mission, called ICESat-2, should provide more precise information on how these frozen surfaces are being affected by global warming. Antarctica, Greenland and the ice floating on the Arctic Ocean have all lost volume in recent decades. ICESat-2 will track ongoing change in unprecedented detail from its vantage point some 500km above the planet.

Scientists searching for extraterrestrial life say they have spotted 72 mysterious signals from an alien galaxy using artificial intelligence (AI). The researchers at the SETI (Search for Extraterrestrial Intelligence) Institute discovered the unusual signals when examining 400 terabytes of radio data from a dwarf galaxy three billion light years away from Earth.

A British astrophysicist who was passed over for the Nobel prize for her discovery of exotic cosmic objects that light up the heavens has won the most lucrative award in modern science. Dame Jocelyn Bell Burnell, a visiting professor at Oxford University, was chosen by a panel of leading scientists to receive the $3m (£2.3m) special Breakthrough prize in fundamental physics for her landmark work on pulsars and a lifetime of inspiring leadership in the scientific community.

Astronauts used tape to temporarily patch up an air leak discovered on the Russian side of the International Space Station. Officials said the gap had caused a small loss in cabin pressure and was "isolated to a hole about two millimetres in diameter". It was temporarily plugged with heat resistant tape but astronauts were later able to do a more permanent fix. NASA and Russian officials stressed the six astronauts were not in any danger.

FAST HAS BEEN in the making for a long time. In the early 2000s, China angled to host the Square Kilometre Array, a collection of coordinated radio antennas whose dishes would be scattered over thousands of miles. But in 2006, the international SKA committee dismissed China, and then chose to set up its distributed mondo-telescope in South Africa and Australia instead. Undeterred, Chinese astronomers set out to build their own powerful instrument. The point of radio telescopes is to sense radio waves from space—gas clouds, galaxies, quasars. By the time those celestial objects’ emissions reach Earth, they’ve dimmed to near-nothingness, so astronomers build these gigantic dishes to pick up the faint signals. But their size makes them particularly sensitive to all radio waves, including those from cell phones, satellites, radar systems, spark plugs, microwaves, Wi-Fi, short circuits, and basically anything else that uses electricity or communicates. Protection against radio-frequency interference, or RFI, is why scientists put their radio telescopes in remote locations: the mountains of West Virginia, the deserts of Chile, the way-outback of Australia.

We live inside a galaxy-wide zombie, says a fascinating new study. Our galaxy, the Milky Way, has apparently had quite an eventual life, “dying” once before. This is according to calculations by the Japanese astronomer Masafumi Noguchi of Tohoku University. Noguchi looked at the history of the Milky Way over a period of 10 billion years. He wanted to explain the mystery of why the stars of the Milky Way can be split into those that are rich in the “alpha” elements like oxygen, silicon and magnesium, and those that are overflowing with iron. The astronomer created a model that shows the existence of two separate periods of star formation.

Those of us who follow science news had a good chuckle when news broke a while back about a mysterious sky phenomenon appearing in auroral and sub-auroral regions dubbed 'Steve'. Well, Steve is actually STEVE, standing for Strong Thermal Emission Velocity Enhancement, and it’s no joke. What it is, on the other hand, is unknown. Appearing in the dark sky as a mostly vertical ribbon of vibrant whites and purples with shimmering offshoots of green, STEVE has been photographed and video-recorded for decades. The scientific community, prompted by the citizen scientists who’ve been capturing images of it, is just now catching up.

Our celestial companion in the midnight sky has been a constant source of wonder and awe. From anyplace on the planet, the brightest thing in the night sky is usually the moon. The moon is our only natural satellite and one of the nearest astronomical bodies at around 240,250 miles or 384,400 km away. The moon has a radius of 1079 miles and is approximately 27% the size of the Earth.

New research shows a black hole-fuelled quasar shining 46 billion times brighter than the Sun is not the lone wolf astronomers once believed. Massachusetts Institute of Technology researchers have found the quasar, PKS 1353-341, is simply so bright it drowns out the light from hundreds of galaxies in a surrounding cluster. Michael McDonald, an assistant professor of physics at MIT’s Kavli Institute of Astrophysics and Space Research, writes in the Astrophysical Journal that the previously unseen cluster is about as massive as 690 trillion suns. For comparison, the Milky Way tips the scales at some 400 billion solar masses.

The United States' last crewed space mission (it was also the final shuttle flight STS-135) launched from Kennedy Space center in 2011. Since then, US astronauts have hitched rides on Russian rockets. Meanwhile, SpaceX, Boeing and NASA are reviving US spaceflight with the "Commercial Crew Program." A boring name for something that's exciting not only for NASA but also the four gentlemen that are testing (and will eventually be aboard) the Dragon spaceship when it launches. To get to that point, SpaceX has spent years working closely with NASA and with astronauts Bob Behnken and Doug Hurley to get everything ready. The experienced astronauts have spent the past three years sharing their expertise with SpaceX on everything from where to place buttons in the craft and building a chair that works best for reaching escape velocity (the velocity needed to escape the gravitational pull of a celestial body. In this case, Earth), to iterating the design of the rather stylish spacesuit they'll be wearing.
