American astronaut who took the celebrated 1968 Earthrise photograph during the Apollo 8 mission to orbit the moonIt may be that the most famous picture from the US space programme is not the shot of Neil Armstrong landing on the moon, but the image of Earth, seen rising above the moon's horizon, an image relayed from space on 24 December 1968 by the crew of Apollo 8 - Frank Borman, Jim Lovell and Bill Anders.It was Anders, who has died aged 90, who snapped the Earthrise" photograph, which was not part of the mission's scheduled protocol. And it was he who read first from the Book of Genesis during their live transmission from lunar orbit that Christmas Eve. Continue reading...

Nine years after his first trip to outer space, Tim Peake is ready to blast off once again. He talks about preparing for the first all-British space mission - and setting his sights on MarsThe astronaut Tim Peake is tracking his cab driver on his phone. The car that will deliver him from our meeting to his next appointment (on a day packed with radio commitments) is late and Peake is calculating the most time-efficient route for us to meander through Soho's traffic, on foot, to reach it. Peake is the seventh UK-born astronaut in space and the first Briton to spacewalk - an unfathomable feat for us, but not for him. Space, he agrees, casting a glance at a printout of the schedule he keeps in his jacket pocket, might be easier to navigate than rush hour on Earth.We have already been chatting for an hour, in a snug above his agent's office. He announced his retirement as a European Space Agency (ESA) astronaut in January 2023, but we're meeting in the wake of news that he is preparing for a return to orbit on the first ever all-British space mission. That mission is due to launch next year and Peake is expected to be announced as the flight's commander within the coming weeks. The radio interviews he's conducting today coincide with a deadline for British businesses to make a case for their science to be included onboard, to be tested in microgravity as a priority for the mission: a strident bid to showcase Britain's Stem capabilities on an outer-world stage.

Rather than stretching to infinity and beyond, the universe may have a topology that can eventually be mappedWe may be living in a doughnut. It sounds like Homer Simpson's fever dream, but that could be the shape of the entire universe - to be exact, a hyperdimensional doughnut that mathematicians call a 3-torus.This is just one of the many possibilities for the topology of the cosmos. We're trying to find the shape of space," says Yashar Akrami of the Institute for Theoretical Physics in Madrid, a member of an international partnership called Compact (Collaboration for Observations, Models and Predictions of Anomalies and Cosmic Topology). In May, the Compact team explained that the question of the shape of the universe remains wide open and surveyed the future prospects for pinning it down. Continue reading...

Two Nasa astronauts were on their way to the International Space Station after Boeing's pioneering Starliner capsule finally made its much-delayed first crewed flight from Cape Canaveral. The liftoff came seven years after the spacecraft's original target date, five years after the failure of an uncrewed test flight and following a more recent series of postponements for technical reasons that resulted launch attempts aborted twice. The veteran astronauts Butch Wilmore and Suni Williams reached orbit 12 minutes after the 10.52am ET launch. If the eight- to 10-day mission is successful, Starliner will give Nasa a second option for ferrying humans to low Earth orbit after SpaceX's Dragon capsule

Exclusive: Massive' discovery raises possibility conditions for life were present almost from dawn of timeAstronomers have detected carbon in a galaxy observed just 350m years after the big bang, in observations that raise the possibility that the conditions for life were present almost from the dawn of time.The observations, made by the James Webb space telescope, suggest that vast amounts of carbon were released when the first generation of stars exploded in supernovae. Carbon is known to have seeded the first planets and is a building block for life as we know it, but was previously thought to have emerged much later in cosmic history. Continue reading...

Before the pandemic, Lucy Keighley ran a gym, worked as a personal trainer and went on gruelling, exhilarating runs. But after three and a half years of illness, she isn't sure she will ever recoverI was incredibly strong and fit," says Lucy Keighley. And she looks it, in the photo she is showing me, taken a few years ago. She is with her best friend, Lorna; they have just completed a 15-mile race on the North York Moors. It was a brutal race," she says. But it was great. I was happy." Today, although it's quite dark in the room (she doesn't get on well with bright light), I can see a tear rolling down her cheek. I don't know if I'm ever going to get back there."Lucy, 49, still runs - across the moors and along the coast - but only in her sleep. I'm so light on my feet. I was never a light-footed runner in real life. But in my dreams I am so light, I can run so far, and it feels joyous." Continue reading...

I can see why scientists think two-way communication is a good idea. But some things are better left unsaidOne of my favourite theories about pet behaviour is that cats see their human owners as fellow cats - just very large, hairless, uncoordinated cats. It's why, or so the lore goes, our pet cats treat us like friendly felines, sometimes licking or rubbing against us.How do I know this titbit? Because at some point in the past few years, I joined the ranks of the pet-obsessed millennials. It crept up on me. One day I was idly thinking how nice it would be to get a kitten, the next I was staring into glistening jade eyes, feeling the vibrations of a purr through warm fur, thinking: Yes, this does seem a fair exchange for lifelong servitude." Now I participate regularly in the OTT pet-parent customs. I take too many photos, I bore people with tales of tails, and perhaps the most universal ritual of all: I Google every single thing my pet does to find out why. Continue reading...

I've managed to conquer my fears and build great friendshipsOn the day I received an offer from my first-choice university, I expected to feel elation and excitement. I had spent years preparing for this moment, and yet when it came, I felt only dread at the thought of freshers' week and all the social challenges this would inevitably involve.I had always been something of a shrinking violet and the fact that I now had a close group of friends at school did not helped to assuagemy social anxiety. I assumed this was a stroke of extreme good luck - a one-off. The potential for rejection seemed immense, and I feared I would spend the next few years in loneliness. Continue reading...

The use of the drugs in treating low mood has sparked debate, not least about the necessity of a hallucinogenic experience. But a new discovery may provide an answerRobitussin has been a staple of American pharmacies since the late 1940s - but since the 1960s, people have swigged bottles of the cough medicine recreationally because, at a high enough dose, its active ingredient, dextromethorphan, can cause hallucinations (so-called robotripping"). Now, that ingredient, common to many cough medications, has a potential new use - as an antidepressant.In recent years, studies have found that conventional antidepressants are only marginally more effective than biologically inactive placebos. Meanwhile, big pharmaceutical companies conduct very little research into mental health drugs. So researchers and sufferers have instead placed their hopes in psychedelic drugs usually considered hallucinatory, such as psilocybin or LSD. Yet the evidence of their effectiveness as an antidepressant comes from small trials, one of the largest involving just 233 people - and no national government medicine regulator has formally approved them for this use. Against this backdrop, a legitimate drug company has quietly moved dextromethorphan beyond robotripping into a, legally approved depression treatment - but with an important twist. Continue reading...
