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 promisingIt 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.

The world’s largest space camera’s first test subject? Broccoli.

The Vera C. Rubin Observatory in Chile is about to get the world's biggest camera for astronomy.The images the camera takes contain billions of pixels.It can capture objects 100 million times fainter than the human eye can see. This camera takes colossal digital pictures. It would take 378 4K ultra-high-definition televisions to display just one of them at full size. So what kind of test picture might one take with such a beast? Well, a head of broccoli, of course.The world's largest digital ca...

Scientists detect a gas that typically indicates the presence of biological life in the atmosphere of Venus

In a press briefing today, scientists rom the Royal Astronomical Society announced a potentially revolutionary scientific discovery: They’ve detected the presence of phosphine in the atmosphere of Venus, which suggests the possible presence of biological life. Phosphine is a gas that’s a known biosignature, which means it’s only present when some for of life is also present – and more than that, it’s a gas that also has no known false positives, at least when detected on Earth, that are mistaken...

Scientists find gas linked to life in atmosphere of Venus

Phosphine, released by microbes in oxygen-starved environments, was present in quantities larger than expectedTraces 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 landscapeThe 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 f...

Scientists discover first 'intermediate-mass' black hole in massive merger

In 2019, scientists detected gravitational waves that were later determined to come from the merging of two so-called "intermediate-mass" black holes.These black holes were thought to exist, but had never been directly observed.The discovery sheds new light on how black holes form. In May 2019, a ripple of gravitational waves passed through Earth after traveling across the cosmos for 7 billion years. The ripple came in four waves, each lasting just a fraction of a second. Although the ancient s...

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 land...

3 wonders of the universe, explained

Most people have seen atoms illustrated in textbooks and know about the Big Bang and the speed of light, but there is a good chance what you think you know is not scientifically accurate.Michelle Thaller, an astronomer and Assistant Director for Science Communication at NASA, is here to clear up the misconceptions and explain why atoms don't actually look that way, why the Big Bang is a misnomer, and why the speed of light is more than just really fast.Is there an edge of space? Does light exper...

SpaceX broke a record by launching 180 satellites in 1 month — accelerating Elon Musk's project to blanket Earth in high-speed internet

President Trump acknowledges Elon Musk after SpaceX launched the manned Crew Dragon spaceship, at the Kennedy Space Center on May 30, 2020, in Cape Canaveral, Florida. Saul Martinez/Getty Images SpaceX launched satellites faster than any other company or agency in history over the last month, as part of Elon Musk's plan to blanket Earth in high-speed internet. The launches hurtled 175 Starlink internet satellites into space, along with five satellites from other companies. The latest satel...

'From the mundane to the sublime in a second': Samantha Cristoforetti on life in space

Her 200 days in orbit turned the first female Italian astronaut into a celebrity – and the model for a Barbie doll. Back on Earth, she says, it was hard to find authentic relationshipsThere’s something surreal about talking to someone who’s been to space. Italian astronaut Samantha Cristoforetti might be at home in Cologne while I’m Zooming her from London – but there’s still an awareness: those eyes have seen what only a handful of people will ever see. Those hands have been without gravity tra...

Somehow, a Tiny Black Hole Is Causing a 'Heartbeat' 100 Light-Years Away

There’s a cloudy patch of space inside our galaxy that unexpectedly produces gamma radiation at clockwork-like intervals. Scientists have now linked these periodic pulses to a “microquasar”—most likely a black hole—located a whopping 100 light-years away, in what is an extraordinary observation.Read more...

A Dusty Burp Could Explain Mysterious Dimming of Supergiant Star Betelgeuse

Doomed supergiant star Betelgeuse has been acting strange lately, appearing far less bright than usual and then bouncing back to normal. Hubble Space Telescope observations from last year suggest the unexpected dimming was caused by a sudden ejection of hot gases, which formed an enormous dust cloud after cooling.Read more...

Inside the genius of Albert Einstein

The word genius is often used to describe Albert Einstein, but what exactly earned the German-born theoretical physicist that descriptor? We have his ideas to thank for many facets of the modern world, but it turns out not everyone thought he was that brilliant."Everybody knows who Einstein is and people understand that he was a very famous scientist," says NASA astronomer Michelle Thaller. "But I think that people often don't grasp the true depth and the profound nature of the things that Einst...
