Students at the University of Manchester in the UK have created a 30,500-piece LEGO model of the iconic Lovell Telescope to mark the 80th anniversary of the Jodrell Bank Observatory.

Jodrell Bank was established in 1945 in Cheshire in northwest England by the English radio astronomer Bernard Lovell, who became the observatory’s first director, a position he held until 1980.

The Lovell Telescope at Jodrell Bank was built in 1957, and at 76.2 m in diameter was the largest steerable dish radio telescope in the world. That year it also became the only instrument capable of tracking the Soviet Union’s Sputnik 1 rocket.

The Lovell Telescope was originally known as the “250 ft telescope” before becoming the Mark I telescope around 1961 and then in 1987 was renamed the Lovell Telescope.

It was given a Heritage Grade I listing in 1988 and in 2019 Jodrell Bank was granted UNESCO World Heritage status.

To the next level

The LEGO model has been designed by Manchester’s undergraduate physics society and is based on the telescope’s original engineering blueprints. Student James Ruxton spent six months perfecting the design, which even involved producing custom-designed LEGO bricks with a 3D printer.

Ruxton and fellow students began construction in April and the end result is a model weighing 30 kg with 30 500 pieces and a whopping 4000-page instruction manual.

“It’s definitely the biggest and most challenging build I’ve ever done, but also the most fun,” says Ruxton. “I’ve been a big fan of LEGO since I was younger, and I’ve always loved creating my own models, so recreating something as iconic as the Lovell is like taking that to the next level!”

The model will now go on display in a “specially modified cabinet” at the university’s Schuster building. It will take pride of place alongside a decade-old LEGO model of CERN’s ATLAS detector.

“Jodrell Bank has always been a symbol of bold innovation – pushing the boundaries of science and engineering from its earliest days,” notes particle physicist Chris Parkes, who is head of physics and astronomy at Manchester. “What the students have created with this Lego build is a perfect reflection of that spirit. It’s not just a model; it’s a celebration of Manchester’s history of discovery and a testament to the creativity, precision, and ambition that continue to define our scientific community today.”

The first spectacular images from the Vera C Rubin Observatory have been released today showing millions of galaxies and Milky Way stars and thousands of asteroids in exquisite detail.

Based in Cerro Pachón in the Andes, the Vera C Rubin Observatory contains the Legacy Survey of Space and Time (LSST) – the largest camera ever built. Taking almost two decades to build, the 3200 megapixel instrument forms the heart of the observatory’s 8.4 m Simonyi Survey Telescope.

The imagery released today, which took just 10 hours of observations, is a small preview of the Observatory’s upcoming 10-year scientific mission.

The image above is of the Trifid and Lagoon nebulas. This picture combines 678 separate images taken by the Vera C Rubin Observatory in just over seven hours of observing time. It reveals otherwise faint or invisible details, such as the clouds of gas and dust that comprise the Trifid nebula (top right) and the Lagoon nebula, which are several thousand light-years away from Earth.

The image below is of the Virgo cluster. It shows a small section of the Virgo cluster, featuring two spiral galaxies (lower right), three merging galaxies (upper right) and several groups of distant galaxies.

Star mapper

Later this year, the Vera C Rubin Observatory, which is funded by the National Science Foundation and the Department of Energy’s Office of Science, will begin a decade-long survey of the southern hemisphere sky.

The LSST will take a complete picture of the southern night sky every 3-4 nights. It will then replicate this process over a decade to produce almost 1000 full images of sky.

This will be used to plot the positions and measure the brightness of objects in the sky to help improve our understanding of dark matter and dark energy. It will examine 20 billion galaxies as well as produce the most detailed star map of the Milky Way, imaging 17 billion stars and cataloguing some six million small objects within our solar system including asteroids.

Cosmic pioneer

The observatory is named in honour of the US astronomer Vera C Rubin. In 1970, working with Kent Ford Jr, they observed that outer stars orbiting in the Andromeda galaxy were all doing so at the same speed.

Examining more galaxies still, they found that their rotation curves – the orbital speed of visible stars within the galaxy compared with their radial distance to the galaxy centre – contradicted Kepler’s law.

They also found that stars near the outer edges of the galaxies were orbiting so fast that they should be falling apart.

Rubin and Ford Jr’s observation led them to predict that there was some mass, dubbed “dark matter”, inside the galaxies responsible for the anomalous motions, something their telescopes couldn’t see but was there in quantities about six times the amount of the luminous matter present.

Computational physicist Jose Milovich of the Lawrence Livermore National Laboratory (LLNL) and colleagues have been awarded the 2025 Plasma Physics and Controlled Fusion (PPCF) Outstanding Paper Prize for their computational research on capsule implosions during laser fusion.

The work – Understanding asymmetries using integrated simulations of capsule implosions in low gas-fill hohlraums at the National Ignition Facility – is an important part of understanding the physics at the heart of inertial confinement fusion (ICF).

Fusion is usually performed via two types of plasma confinement. Magnetic involves using magnetic fields to hold stable a plasma of deuterium-tritium (D-T), while inertial confinement uses rapid compression, usually by lasers, to create a confined plasma for a short period of time.

The award-winning work was based on experiments carried out at the National Ignition Facility (NIF) based in California, which is one of the leading fusion centres in the world.

During NIF’s ICF experiments, a slight imbalance of the laser can induce motion of the hot central core of an ignition capsule, which contains the D-T fuel. This effect results in a reduced performance.

Experiments at NIF in 2018 found that laser imbalances alone, however, could not account for the motion of the capsule. The simulations carried out by Milovich and colleagues demonstrated that other factors were at play such as non-concentricity of the layers of the material surrounding the D-T fuel as well as “drive perturbations” induced by diagnostic windows on the implosion.

Changes made following the team’s findings then helped towards the recent demonstration of “energy breakeven” at NIF in December 2022.

Awarded each year, the PPCF prize aims to highlight work of the highest quality and impact published in the journal.  The award was judged on originality, scientific quality and impact as well as being based on community nominations and publication metrics. The prize will be presented at the 51st European Physical Society Conference on Plasma Physics in Vilnius, Lithuania, on 7–11 July.

The journal is now seeking nominations for next year’s prize, which will focus on papers in magnetic confinement fusion.

Below, Milovich talks to Physics World about prize, the future of fusion and what advice he has for early-career researchers.

What does winning the 2025 PPCF Outstanding Paper Prize mean to you and for your work?

The award is an incredible honour to me and my collaborators as a recognition of the detailed work required to make inertial fusion in the laboratory a reality and the dream of commercial fusion energy a possibility. The paper presented numerical confirmation of how seemingly small effects can significantly impact the performance of fusion targets.  This study led to target modifications and revised manufacturing specifications for improved performance.  My collaborators and I would like to deeply thank PPCF for granting us this award.

What excites you about fusion?

Nuclear fusion is the process that powers the stars, and achieving those conditions in the laboratory is exciting in many ways.  It is an interesting scientific problem in its own right and it is an incredibly challenging engineering problem to handle the extreme conditions required for successful energy production. This is an exciting time since the possibility of realizing this energy source became tangibly closer two years ago when NIF successfully demonstrated that more energy can be released from D-T fusion than the laser energy delivered to the target.

What are your thoughts on the future direction of ICF and NIF?

While the challenges ahead to make ICF commercially feasible are daunting, we are well positioned to address them by developing new technologies and innovative target configurations. Applications of artificial intelligence to reactor plant designs, optimized operations, and improvements on plasma confinement could potentially lead to improved designs at a fraction of the cost. The challenges are many but the potential for providing a clean and inexhaustible source of energy for the benefit of mankind is invigorating.

What advice would you give to people thinking about embarking on a career in fusion?

This is an exciting time to get involved in fusion. The latest achievements at NIF have shown that fusion is possible. There are countless difficulties to overcome, making it an ideal time to devote one’s career in this area. My advice is to get involved now since, at this early stage, any contribution will have a major and lasting impact on mankind’s future energy needs.

Astronomers at the European Southern Observatory’s Very Large Telescope (VLT) have created a thousand colour image of the nearby Sculptor Galaxy.

First discovered by Carloine Herschel in 1783 the spiral galaxy lies 11 million light-years away and is one of the brightest galaxies in the sky.

While conventional images contain only a handful of colours, this new map contains thousands, which helps astronomers to understand the age, composition and motion of the stars, gas and dust within it.

To create the image, researchers observed the galaxy for over 50 hours with the Multi Unit Spectroscopic Explorer (MUSE) instrument on the VLT, which is based at the Paranal Observatory in Chile’s Atacama Desert.

The team then stitched together over 100 exposures to cover an area of the galaxy about 65 000 light-years wide.

The image revealed around 500 planetary nebulae – regions of gas and dust cast off from dying Sun-like stars – that can be used as distance markers to their host galaxies.

“Galaxies are incredibly complex systems that we are still struggling to understand,” notes astronomer Enrico Congiu, lead author of the study. “The Sculptor Galaxy is in a sweet spot – it is close enough that we can resolve its internal structure and study its building blocks with incredible detail, but at the same time, big enough that we can still see it as a whole system.”

Future work will involve understanding how gas flows, changes its composition, and forms stars in the galaxy.  “How such small processes can have such a big impact on a galaxy whose entire size is thousands of times bigger is still a mystery,” adds Congiu.

The Japanese firm ispace has suffered another setback after its second attempt to land on the Moon ended in failure yesterday. The Hakuto-R Mission 2, also known as Resilience, failed to touch down near the centre of Mare Frigoris (sea of cold) in the far north of the Moon after a sensor malfunctioned during descent.

Launched on 15 January from the Kennedy Space Center, Florida, aboard a SpaceX Falcon 9 rocket, the craft spent four months travelling to the Moon before it entered lunar orbit on 7 May. It then spent the past month completing several lunar orbital manoeuvres.

During the descent phase, the 2.3 m-high lander began a landing sequence that involved firing its main propulsion system to gradually decelerate and adjust its attitude. ispace says that the lander was confirmed to be nearly vertical but then the company lost communication with the craft.

The firm concludes that the laser rangefinder experienced delays attempting to measure the distance to the lunar surface during descent, meaning that it was unable to decelerate sufficiently to carry out a soft landing.

“Given that there is currently no prospect of a successful lunar landing, our top priority is to swiftly analyse the telemetry data we have obtained thus far and work diligently to identify the cause,” noted ispace founder and chief executive officer Takeshi Hakamada in a statement. “We strive to restore trust by providing a report of the findings.”

The mission was planned to have operated for about two weeks. Resilience featured several commercial payloads, worth $16m, including a food-production experiment and a deep-space radiation probe. It also carried a rover, dubbed Tenacious, which was about the size of a microwave oven and would have collected and analysed lunar regolith.

The rover would have also delivered a Swedish artwork called The Moonhouse – a small red cottage with white corners – and placed it at a “symbolically meaningful” site on the Moon.

Lunar losses

The company’s first attempt to land on the Moon also ended in failure in 2023 when the Hakuto-R Mission 1 crash landed despite being in a vertical position as it carried out the final approach to the lunar surface.

The issue was put down to a software problem that incorrectly assessed the craft’s altitude during descent.

If the latest attempt was a success, ispace would have joined the US firms Intuitive Machines and Firefly Aerospace, which both successfully landed on the Moon last year and in March, respectively.

The second lunar loss casts doubt on ispace’s plans for further lunar landings and its grand aim of establishing a lunar colony of 1000 inhabitants by the 2040s.

The Leinweber Foundation has awarded five US institutions $90m to create their own theoretical research institutes. The investment, which the foundation says is the largest ever for theoretical physics research, will be used to fund graduate students and postdocs at each institute as well as several Leinweber Physics Fellows.

The Leinweber Foundation was founded in 2015 by the software entrepreneur Larry Leinweber. In 1982 Leinweber founded the software company New World Systems Corporation, which provided software to the emergency services. In 2015 he sold the company to Tyler Technologies for $670m.

Based in Michigan, Leinweber Foundation supports research, education and community endeavours where it has provided Leinweber Software Scholarships to undergraduates at Michigan’s universities.

A Leinweber Institute for Theoretical Physics (LITP) will now be created at the universities of California, Berkeley, Chicago and Michigan as well as at the Massachusetts Institute of Technology (MIT) and at Princeton’s Institute for Advanced Study (IAS), where the institute will instead be named the Leinweber Forum for Theoretical and Quantum Physics.

The MIT LIPT, initially led by Washington Taylor before physicist Tracy Slatyer takes over later this year, will receive $20m from the foundation and will provide support for six postdocs, six graduate students as well as visitors, seminars and “other scholarly activities”.

“This landmark endowment from the Leinweber Foundation will enable us to support the best graduate students and postdoctoral researchers to develop their own independent research programmes and to connect with other researchers in the Leinweber Institute network,” says Taylor.

Spearing innovation

UC Berkeley, meanwhile, will receive $14.4m from the foundation in which the existing Berkeley Center for Theoretical Physics (BITP) will be renamed LITP at Berkeley and led by physicist Yasunori Nomura.

The money will be used for four postdoc positions to join the existing 15 at the BITP as well as to support graduate students and visitors. “This is transformative,” notes Nomura. “The gift will really have a huge impact on a wide range of research at Berkeley, including particle physics, quantum gravity, quantum information, condensed matter physics and cosmology.”

Chicago will receive $18.4m where the existing Kadanoff Center for Theoretical Physics will be merged into a new LITP at the University of Chicago and led by physicist Dam Thanh Son.

The remaining $37.2m will be split between the Leinweber Forum for Theoretical and Quantum Physics at the IAS and at Michigan, in which the existing Leinweber Center for Theoretical Physics will expand and become an institute.

“Theoretical physics may seem abstract to many, but it is the tip of the spear for innovation. It fuels our understanding of how the world works and opens the door to new technologies that can shape society for generations,” says Leinweber in a statement. “As someone who has had a lifelong fascination with theoretical physics, I hope this investment not only strengthens U.S. leadership in basic science, but also inspires curiosity, creativity, and groundbreaking discoveries for generations to come.”

China has launched its first mission to retrieve samples from an asteroid. The Tianwen-2 mission launched at 01:31 a.m. local time on 28 May from the Xichang satellite launch centre, south-west China, aboard a Long March B rocket.

Tianwen-2’s target is a small near-Earth asteroid called 469219 Kamoʻoalewa, which is 15–39 million km away and is known as a “quasi-satellite” of Earth.

The mission is set to reach the body, which is 40–100 m wide, in July 2026. It will first study it up close using a suite of 11 instruments including cameras, spectrometers and radar, before aiming to collect about 100 g of material.

This will be achieved via three possible methods. One is via hovering close to the asteroid; another is using a robotic arm to collect samples from the body; while a third is dubbed “touch and go”, which involves gently landing on the asteroid and using drills at the end of each leg to retrieve material.

The collected samples will then be stored in a module that is released and returned to Earth in November 2027. If successful, it will make China the third nation to retrieve asteroid material behind the US and Japan.

Next steps

The second part of the 10-year mission involves using Earth for a gravitational swing-by to spend six year travelling to another target – 311P/PanSTARRS. The body lies in the main asteroid belt between Mars and Jupiter and at its closest distance is about 140 million km away from Earth.

The 480 m-wide object, which was discovered in 2013, has six dust tails and has characteristics of both asteroids and comets. Tianwen-2 will not land on 311P/PanSTARRS but instead use its instruments to study the “active asteroid” from a distance.

Tianwen-2’s predecessor, Tianwen-1, was China’s first mission to Mars, successfully landing on Utopia Planitia – a largely flat impact basin but scientifically interesting with potential water-ice underneath – following a six-month journey.

China’s third interplanetary mission, Tianwen-3, will aim to retrieve sample from Mars and could launch as soon as 2028. If successful, it would make China the first country to achieve the feat.
