Witnesses also reported seeing an ambulance at the scene.

After firefighters left, the building remained accessible and was not cordoned off.

Residents have since raised concerns about the condition of the derelict property, saying it contains broken glass, rubbish and other debris and warning that it poses a potential safety hazard as people can still enter the site.

The cause of the fire has not been confirmed.

The North West Ambulance Service has been contacted for comment.

The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star – a red dwarf located some 48 light years from Earth.

The habitable zone is the region around the star where temperatures are just right for water to remain liquid at a planet’s surface. Astronomers detected helium being lost from the upper atmosphere of LHS 1140b. But heavier chemical compounds, such as water, which is a key ingredient for life, could exist lower in its atmosphere.

Observing distant exoplanets using telescopes opens new doors for science, but will it ever be possible to travel to these worlds and observe them up close? While this has generally been seen as the stuff of science fiction until now, emerging technologies allow us to imagine a future where such missions are possible in the decades ahead.

There is particular interest in miniaturised spacecraft for interstellar voyages. In large part, this is because it’s easier and cheaper to propel a small spacecraft to another star system – and have it get there within a person’s lifetime – than it is to do the same with a large vehicle.

Miniaturisation of sensors has seen great advances, for example through smart phone technology where highly capable cameras with low mass, power and volume are routinely used. Researchers have even developed “smart dust”; sensors that are millimetre-scale in size or smaller that can detect light, temperature or chemicals.

The space probe itself would need a form of propulsion capable of accelerating it to mildly relativistic speeds, say 10-20% of the speed of light. After a travel time of many decades, the sensors would pass through a target star system without stopping, making in-situ observations and then very slowly drip data back to Earth.

This isn’t quite Star Trek, but it’s a potentially plausible idea that would enable us to study neighbouring stars and their planets up close. This kind of concept has been actively pursued by a philanthropically funded venture known as Breakthrough Starshot. This programme investigated the key technologies required for an interstellar journey using small probes.

Lights sails are seen as one of the most suitable forms of propulsion for such a mission. As the name implies, these are thin reflective membranes.

For interstellar travel, directed energy from a laser could be used to push the spacecraft forward. Photons, the quantum packets of energy of which light is composed, transport momentum as well as energy. Therefore, when light reflects off a mirror it exerts a pressure on the mirror.

In most circumstances the pressure due to light is imperceptibly small. However, for an intense enough beam of light, and an ultra-lightweight membrane mirror, light pressure can act as a means of spacecraft propulsion.

In order to accelerate a light sail to relativistic speeds, a hefty laser would be required, with an effective power of tens of gigawatts. This wouldn’t be a single device. Instead, it would probably comprise an array of separate laser devices synchronised together to generate a beam of coherent light.

Accelerated to the stars

Pushing a reflective light sail a few metres across with such a laser would accelerate the sail to its cruising speed in a matter of minutes.

The advantage of beam-power propulsion systems is that the laser assembly is left behind and only a small payload is accelerated to the stars. In contrast, conventional rockets have to haul their own propellant, which puts them at a severe disadvantage for such ultra-high energy missions.

The disadvantage of beam power propulsion is that the payload can’t easily stop, so a probe would pass through its target star system in only a few days.

While multi-gigawatt laser-pushed light sails may seem to be a bit of a stretch at present due to the colossal scale of such a venture, advances in miniaturisation could pave the way for tiny intelligent sensor nodes to be our first interstellar voyagers.

Perhaps we’ll first travel to the stars with an AI asleep at the wheel for decades, until it awakens for a few days of frantic activity as our machine proxies get their first glimpse of alien worlds.

Aside from pushing light sails with gigawatt lasers, reflective membranes can also be pushed by light pressure from the Sun. These “solar sails” have a long and rich history and were first proposed in the 1920s by Konstantin Tsiolkovsky and Friedrich Tsander, two of the great Russian pioneers of astronautics. Tsiolkovsky wrote of using “tremendous mirrors of very thin sheets”.

Tools for exploring

While laser-propelled light sails are for the future, solar sails are for the present. A number of small solar sails have already been launched into Earth orbit for technology demonstration purposes. Scaling up solar sails for deep space missions could deliver a new set of tools for exploring our solar system.

First, since solar sails do not need to carry propellant, they are capable of high-energy, long-duration missions, some of which are just about impossible for conventional spacecraft. For example, to rendezvous with a long period comet on an elliptical or highly inclined orbit about the Sun requires significant energy.

Moreover, returning a surface sample from such a comet to Earth becomes even more difficult. For conventional rocket propulsion, the spacecraft needs to haul propellant for the return journey all the way to the target comet.

For solar sails, returning to Earth is little different to reaching the comet in the first place. Solar sails can “tack” by tilting the sail to gain momentum and so spiral away from the Sun, or flipping the sail to lose momentum and spiral back inwards towards the Sun.

Solar sails can also move along unconventional orbits with light pressure used to offset gravity. For example, this could allow a solar sail to hover stationary high above the poles of the Earth.

Solar sails and light sails are stepping stones from the present to the future, and from exploring our own solar system to exploring distant stars. Perhaps exoplanet LHS 1140b will be visited by a light sail at some point in our future.

The devasting wildfire at Llanwonno Wildfire has been stood down from major incident status on Thursday evening.

Firefighters will remain at the scene for the coming days to damp down any hotspots, South Wales Fire and Rescue Service said in an update.

All local roads that were closed have now been re-opened.

“Following successful aerial firefighting support from Natural Resources Wales (NRW) and the continued efforts of firefighters and partner agencies, significant progress has been made in bringing the incident under control,” SWFRS said.

” We are pleased to confirm that all properties in the area remain protected. Firefighters will continue to maintain a presence at the scene over the coming days to dampen down remaining hotspots, and tackle the ongoing peat fire on Penrhys Mountain.

“Our Fire Crime Team will remain in the community, providing fire safety advice and support to residents affected by the incident. South Wales Police will also continue their routine patrols in the area. All local road closures have now been lifted.

“We would like to express our sincere thanks to the local community for their patience, understanding and support throughout this incident. We are particularly grateful for the many kind messages received as our crews, alongside partner agencies, worked tirelessly to bring this challenging wildfire under control.”

Amanda Knox, who was convicted and later acquitted of murdering British student Meredith Kercher in Italy in 2007, has defended her solo comedy show following calls for it to be cancelled.

The sold-out show called Cartwheel, which Knox will perform at the Edinburgh Festival Fringe, discusses motherhood and how she will explain the case to her daughter.

Knox told the BBC she is not the first person to use comedy to talk about traumatic events and said her material focuses on “how the world is unsafe and unfair towards women”.

But Stephanie Kercher, the victim’s sister, said she is concerned it will “normalise and trivialise” violence against women, and Meredith, in particular.

Speaking on BBC Breakfast, Stephanie Kercher, said: “What I would say [to Knox] is to think about the family here, think about her friends and to turn the tables if it was your sister that this had happened to, because I know you have a sister as well.”

Responding to the comments, Knox said: “The interesting irony of that is that my daughter is a huge motivation for me doing this show.

“It’s about how the world is unsafe and unfair towards women and what it means to raise a daughter in that world, knowing how bad it can be.

“If they [Kercher’s family] saw my show, they would recognise that.”

A petition against the show, set up by a friend of Meredith, has been signed by nearly 5,000 people.

It states the show disrespects her memory and risks making light of such a harrowing event.

CHAPEL HILL, N.C. (AP) — North Carolina defensive coordinator Steve Belichick, the son of head coach Bill Belichick, is on medical leave, his father said Thursday morning.

The Tar Heels are in the second week of preseason camp. UNC opens the season Aug. 29 against TCU in Dublin, Ireland.

“It’s a medical situation so I really can’t make any further comment on that,” Belichick said, adding only that the team hoped to have him back “as soon as possible” when asked about a timeline for his return.

He also said the defensive staff already works “collectively” when asked how the team would adjust during his son’s absence.

UNC’s defense improved as a 4-8 season wore on, ranking 38th in the Bowl Subdivision ranks in total defense (336.9 yards) while finishing tied for 20th with 2.67 sacks per game.

Steve Belichick joined his father’s staff ahead of the NFL coaching great’s first college season last year, following a year as the University of Washington’s defensive coordinator. Before that, he had worked on his father’s staff with the NFL’s New England Patriots.

Last week the school announced general manager Michael Lombardi had been placed on paid administrative leave and was the subject of a school investigation.

Senator Mitch McConnell has been discharged from a medical rehabilitation center, he announced on Thursday.

“Earlier today, I was discharged from the rehabilitation center to continue my recovery at home,” McConnell said in a statement. “Elaine and I are grateful for the many well wishes and support from friends, colleagues, and Kentuckians, and for the attentive care I’ve received from excellent doctors, nurses, therapists, and hospital staff.”

The Kentucky Republican was hospitalized in mid-June and has been out of Congress since, prompting alarm and widespread speculation over his health.

Weeks after entering the hospital, McConnell disclosed he was admitted after a fall and had since developed a case of mild pneumonia.

“My doctors have confirmed that I didn’t break any bones or suffer a concussion,” McConnell said in a statement at the time. “I didn’t have a heart attack or a stroke. I don’t have any tumors or hemorrhages. But I was briefly unconscious and was taken to the hospital.”

After his discharge, the 84-year-old will not be returning to Capitol Hill just yet.

“On the advice of my doctors, I’ll maintain an intensive regimen of physical therapy from home during the state work period, and I’ll continue to engage with my staff and colleagues on important Senate business,” McConnell wrote in his statement on Thursday.

McConnell’s lengthy absence from the Senate has been a subject of intense interest and debate in Washington and beyond, as the Trump administration looks to lock in any final legislative wins ahead of the November midterms, where Democrats could retake control of Congress.

Republican senators and conservative commentators insist they have spoken with McConnell and that he remains engaged and physically sound to carry on in office, though McConnell himself hasn’t appeared in any live video appearances that might assure doubters.

Kentucky Governor Andy Beshear, a Democrat, has called on McConnell to “directly and verbally address the people of Kentucky and provide proof of your capacity to serve, or resign.”

If McConnell resigned his position, or was otherwise incapacitated or died, a special election could be called to replace him.

McConnell’s hospitalization came after a series of past medical scares, including falls and incidents where the senator froze mid-sentence.

His absence, as well as the recent death of Sen. Lindsey Graham, 71, reignited the long-running debate over whether members of Congress are too old to serve.

About 58 percent of Americans think the share of elderly lawmakers in Congress, which is currently one of the oldest in U.S. history, is a major problem, according to a July CNN / SSRS poll.
