Burst of radio waves in Milky Way probably came from neutron star

First fast radio burst found in our galaxy is traced to magnetar 30,000 light years away

For more than a decade, astronomers have puzzled over the origins of mysterious and fleeting bursts of radio waves that arrive from faraway galaxies.

Now, scientists have discovered the first such blast in the Milky Way and traced it back to its probable source: a small, spinning remnant from a collapsed star about 30,000 light years from Earth.

Water exists on the moon, scientists confirm

Proof of significant amounts of H2O has implications for future lunar missions

Scientists have gathered some of the most compelling evidence yet for the existence of water on the moon – and it may be relatively accessible. The discovery has implications for future missions to the moon and deeper space exploration.

With no significant atmosphere insulating it from the sun’s rays, it had been assumed that the moon’s surface was dry – until the 1990s, when orbiting spacecraft found indications of ice in large and inaccessible craters near the moon’s poles.

Overstuffed Nasa spacecraft Osiris-Rex losing particles after bingeing on Bennu

After an asteroid encounter, scientists scrambled to minimize the loss of space rocks as the craft belched rubble

A Nasa spacecraft is stuffed with so much asteroid rubble from this week’s grab that it’s jammed open and precious particles are drifting away in space, scientists said on Friday.

Nasa Osiris-Rex spacecraft lands on asteroid Bennu in mission to collect dust

Spacecraft ‘kissed the surface’ in brief landing on asteroid 200m miles away from Earth in US-first mission

A Nasa spacecraft has successfully landed on an asteroid, dodging boulders the size of buildings, in order to collect a handful of cosmic rubble for analysis back on Earth.

The space agency team behind the Osiris-Rex project said preliminary data showed the sample collection went as planned and that the spacecraft had lifted off the surface of asteroid Bennu.

Talking on the moon: Nasa and Nokia to install 4G on lunar surface

Move is part of US space agency’s plan to establish a long-term human presence on the moon by 2030

With competition among Earth’s telecoms providers as fierce as ever, equipment maker Nokia has announced its expansion into a new market, winning a deal to install the first cellular network on the moon.

The Finnish equipment manufacturer said it was selected by Nasa to deploy an “ultra-compact, low-power, space-hardened” wireless 4G network on the lunar surface, as part of the US space agency’s plan to establish a long-term human presence on the moon by 2030.

Residents of remote Scottish peninsula face up to its future as spaceport

The Mhoine peninsula in Sutherland will house one of UK’s first sites of its kind if it wins approval

In two years, thousands of tourists and space enthusiasts could be gathering in the far north of Scotland to watch an unlikely event, the inaugural flight of a rocket blasting off from a peat bog usually grazed by deer and sheep.

The Mhoine peninsula in Sutherland, a desolate stretch of peatland punctuated by mires and tiny lochs overlooking the Pentland Firth, has been chosen as the site of one of the UK’s first spaceports – provided it eventually wins approval from the Civil Aviation Authority.

Three scientists share Nobel prize in physics for work on black holes

Roger Penrose says win, shared with Reinhard Genzel and Andrea Ghez, ‘is in some ways a distraction’

Three scientists have won the 2020 Nobel prize in physics for their work on black hole formation and the discovery of a supermassive black hole at the centre of our galaxy.

Sir Roger Penrose, Reinhard Genzel and Andrea Ghez together scooped the 114th Nobel prize in physics.

Astronauts trace air leak to Russian side of space station after midnight alarm

Nasa officials stress that the leak on ISS remains small and poses no danger but will send extra air supply on the next delivery

A small air leak at the International Space Station finally has been traced to the Russian side, following a middle-of-the-night search by astronauts.

Nasa said on Tuesday that the two Russians and one American on board were awakened late Monday to hurriedly seal hatches between compartments and search for the ongoing leak, which appeared to be getting worse. It was the third time in just over a month that the crew had to isolate themselves on the Russian side, in an attempt to find the growing leak.

Salty ponds may be under Mars’ icy surface, raising prospect of Martian life

Italian scientists provide further evidence of underground lake and smaller bodies of water in study

A network of salty ponds may be gurgling beneath Mars’ south pole alongside a large underground lake, raising the prospect of tiny, swimming Martian life.

Italian scientists reported their findings Monday, two years after identifying what they believed to be a large buried lake. They widened their coverage area by a couple hundred miles, using even more data from a radar sounder on the European Space Agency’s Mars Express orbiter.

The search for life – from Venus to the outer solar system

While the discovery of the normally microbe-produced phosphine on our toxic neighbour is astonishing, other candidates for life are more promising

It remains one of the most unexpected scientific discoveries of the year. To their astonishment, British scientists last week revealed they had uncovered strong evidence that phosphine – a toxic, rancid gas produced by microbes – exists in the burning, acid-drenched atmosphere of Venus.

Scientists find gas linked to life in atmosphere of Venus

Phosphine, released by microbes in oxygen-starved environments, was present in quantities larger than expected

Traces of a pungent gas that waft through the clouds of Venus may be emanations from aerial organisms – microbial life, but not as we know it.

Astronomers detected phosphine 30 miles up in the planet’s atmosphere and have failed to identify a process other than life that could account for its presence.

Are Elon Musk’s ‘megaconstellations’ a blight on the night sky?

Miniature satellites open up a world of technological possibility. But experts say they degrade the astronomical landscape

The natural serenity of the night sky is a touchstone for all of us. Everyone alive today looks at the same stars no matter where they are located on the planet. But the connection is more profound because, next to our brief lives, the stars are immortal. Shakespeare saw the same stars in the same patterns that we do. So did Galileo, Columbus, Joan of Arc, Cleopatra and the first human ancestor to look up in curiosity. The night sky is nothing short of our common human heritage.

Last year, however, something happened that might change that view for ever. On 23 May 2019, Elon Musk’s company SpaceX launched 60 small satellites from a single rocket. The satellites were the first in what is planned to be a “megaconstellation” of thousands of satellites that will bring internet coverage to the entire planet.

Nasa is looking for private companies to help mine the moon

The agency announced it is buying lunar soil from a commercial provider as part of a technology development program

Nasa has announced it is looking for private companies to go to the moon and collect dust and rocks from the surface and bring them back to Earth.

The American space agency would then buy the moon samples in amounts between 50 to 500 grams for between $15,000 to $25,000.

Are aliens hiding in plain sight?

Several missions this year are seeking out life on the red planet. But would we recognise extraterrestrials if we found them?

In July, three unmanned missions blasted off to Mars – from China (Tianwen-1), the US (Nasa’s Mars 2020 Perseverance Rover) and the United Arab Emirates (Hope). The Chinese and American missions have lander craft that will seek signs of current or past life on Mars. Nasa is also planning to send its Europa Clipper probe to survey Jupiter’s moon Europa, and the robotic lander Dragonfly to Saturn’s moon Titan. Both moons are widely thought to be promising hunting grounds for life in our solar system – as are the underground oceans of Saturn’s icy moon Enceladus.

Meanwhile, we can now glimpse the chemical makeup of atmospheres of planets that orbit other stars (exoplanets), of which more than 4,000 are now known. Some hope these studies might disclose possible signatures of life.

‘It just sounds like a thud’: astronomers hear biggest cosmic event since big bang

Researchers believe noise was two black holes colliding around 7 billion years ago, creating a previously unseen class of stellar object

Scientists have announced the detection of a signal from a long-ago collision between two black holes that created a new one of a size never seen before.

“It’s the biggest bang since the big bang observed by humanity,” said Caltech professor of physics Alan Weinstein, who was part of the discovery team.

Planet Ceres is an ‘ocean world’ with sea water beneath surface, mission finds

Dwarf planet, believed to be a barren space rock, has an ‘extensive reservoir’ of brine beneath its surface, images show

The dwarf planet Ceres – long believed to be a barren space rock – is an ocean world with reservoirs of sea water beneath its surface, the results of a major exploration mission showed on Monday.

Ceres is the largest object in the asteroid belt between Mars and Jupiter and has its own gravity, enabling the Nasa Dawn spacecraft to capture high-resolution images of its surface.

Nasa to change ‘harmful’ and insensitive’ planet and galaxy nicknames

Space agency says ‘certain cosmic nicknames are insensitive’ and vows to drop any reference to them

Nasa has signaled it is joining the social justice movement by changing unofficial and potentially contentious names used by the scientific community for distant cosmic objects and systems such as planets, galaxies and nebulae.

In a statement last week, the space agency said that as the “community works to identify and address systemic discrimination and inequality in all aspects of the field, it has become clear that certain cosmic nicknames are not only insensitive, but can be actively harmful”.
