On the staff side of things we have been working very hard to implement our new curriculum - which has now rolled through from year 1 all the way into year 4. The new curriculum covers all of the Institute of Physics core areas of physics, and enhances our focus on specialist electives and on transferrable skills. This is working well! Students like the new modules and returned NSS overall satisfaction results of greater than 90% - the second highest of any Department on campus. Perhaps most importantly, following a very successful visit the Institute of Physics recently re-accredited all of our degrees for the maximum possible term.

This workshop is a fantastic opportunity for students to ask and speak with a number of experts with wide- ranging human spaceflight related expertise and experiences.

“It is not every day you are able to meet an astronaut or a trained astronaut instructor. It is also not every day you meet an expert who understands the importance of psychology in human space exploration and meet people who have been involved in designing technology and environments for astronauts to use and work in.

The European Space Agency and the UK Space Agency are funding Leicester scientists designing an instrument for a new mission called THESEUS, which will dramatically increase the rate of discovery of explosive transients in the universe. Leicester leads the primary soft X-ray instrument (SXI) on THESEUS. The SXI is designed to detect the most distant, luminous transients – Gamma-Ray Bursts (GRBs) – which typically last for only a few tens to hundreds of seconds.

Launched from Cape Canaveral on Nov 20, 2004, the Swift satellite was designed to answer the many questions about the enigmatic cosmic explosions known as Gamma-Ray Bursts. It is a novel autonomous rapid-reaction spacecraft with a Extremely energetic cosmic explosions generate gamma-ray multi-wavelength payload of telescopes.

One of the projects which used the new DiRAC computers was a study into the distribution of unusual galaxies called RELHICs (REionisation-Limited H I Clouds) which are thought to contain dark matter and gas, but no stars. At the other end of the scale, another project examined the decay rates of a subatomic particle called a ‘b-quark’ to find out why experimental results from the Large Hadron Collider appear to differ from theoretical predictions.

Professor Wilkinson noted that the impact of DiRAC extends much further than the scientific breakthroughs it delivers: “We are also contributing to the delivery of the UK’s innovation agenda. We work with our industry partners to

The thermal glow gives astronomers another window onto the rings, which have been seen only because they reflect a little light in the visible, or optical, range and in the near-infrared. The new images taken by the Atacama Large Millimeter/submillimeter Array (ALMA) and the Very Large Telescope (VLT) allowed the team for the first time to measure the temperature of the rings: a cool 77 Kelvin, or 77 degrees above absolute zero — the boiling temperature of liquid nitrogen and equivalent to -196 degrees Celsius.

Dr Richard West, from the Department of Physics at the NGTS-4b, also nicknamed the ‘Forbidden Planet’ by University of Warwick, commented: “This planet must be researchers, is a planet 20% smaller than Neptune but three tough - it is right in the zone where we expected Neptune- times the size of Earth.

This discovery hinged on a crucial observation taken by University of Leicester astronomers, using a telescope at the South African Astronomical Observatory: Dr Burleigh and Dr Longstaff confirmed that the transit, and therefore the exoplanet, was real. This alerted the rest of the NGTS consortium to the exciting potential of this exoplanet, and prompted a rush to collect further data. Researchers believe the planet may have moved into the Neptunian Desert recently, in the last one million years, or that it was very big and its atmosphere is still evaporating.

SXI will be the first instrument to provide true global imaging of the solar wind exchange process within the magnetosphere. The results of which will have meaningful implications for safeguarding our environment on Earth.”

Rare extreme space weather could disrupt modern technology by causing geomagnetic storms affecting satellite navigation, shortwave communications and power grids.

ExoMars rover named after DNA pioneer High-speed supernova reveals earliest (February 2019) moments of a dying star (January 2019)

The European Space Agency has named its new ExoMars rover An international team of scientists, including astronomers Rosalind Franklin, after the DNA pioneer, it has been from the Universities of Leicester, Bath and Warwick, have announced. found evidence for the existence of a 'hot cocoon' of material enveloping a relativistic jet escaping a dying star. ExoMars (Exobiology on Mars) is a joint mission of the European Space Agency (ESA) and the Russian space agency Roscosmos to search for evidence of life on Mars. The University of Leicester is involved in two of the instruments that will equip the Rosalind rover. The name was decided by a panel of experts from a list of possibilities suggested by nearly 36,000 members of the public.

A relativistic jet is a very powerful phenomena which involves plasma jets shooting out of black holes at close to the speed of light, and can extend across millions of light years.

Observations of supernova SN2017iuk taken shortly after its onset showed it expanding rapidly, at one third of the speed of light. This is the fastest supernova expansion measured to date. Monitoring of the outflow over many weeks revealed a In November 2018 over 100 delegates from academia and clear difference between the initial chemical composition and industry met at the National Space Centre in Leicester to that at later times. select the landing site for the ExoMars rover. After four years of careful study, The Landing Site Selection Working Group Taken together, these are indicators of the presence of the opted for Oxia Planum as their preferred site, because its fine much-theorised hot cocoon, filling a gap in our knowledge of sediments would be perfect for the rover’s drill. The decision how a jet of material escaping a star interacts with the stellar will be officially confirmed early this year. envelope around it and providing a potential link between two previously distinct classes of supernovae. Professor John Bridges, Professor of Planetary Science from University of Leicester's Department of Physics and The supernova signals the final demise of a massive star, in Astronomy, said: “The University of Leicester has a major which the stellar core collapses and the outer layers are commitment and a variety of roles in the exploration of Mars, violently blown off.

Until now, astronomers have been unable to study the earliest SN2017iuk also provides a long-sought link between the moments in the development of a supernova of this kind (a supernova that accompany GRBs, and those that do not: in GRB-SN), but SN2017iuk was fortuitously close-by – at roughly lone supernovae, high speed outflows have also been seen, 500 million light years from Earth – and the GRB light was with velocities reaching 50,000 kilometres per second, which underluminous, allowing the SN itself to be detectable at early can originate in the same cocoon scenario but escape of the times. Dr Rhaana Starling, Associate Professor in the relativistic GRB jet is somehow thwarted. Core-collapse University of Leicester’s Department of Physics and supernovae without GRBs are usually found much later after Astronomy said: "This immediately looked like an event worth their onset, giving scientists very little chance of detecting any chasing, as it happened in a grand-design spiral galaxy at very signatures of a hot cocoon, whilst cocoon features in GRB- close proximity, cosmologically speaking. When the first sets associated supernovae are usually hidden by the bright, of data came in there was an unusual component to the light relativistic jet.

The event was first detected using the Neil Gehrels Swift Observatory. Swift is a NASA space mission in which the University of Leicester is one of three partners, and hosts its UK data centre. Data obtained with the Gravitational-wave Optical Transient Observatory (GOTO) helped to track the supernova light, while spectroscopy was obtained through dedicated observing programmes including initiatives by the STARGATE Collaboration headed up by Professor Nial Tanvir at the University of Leicester, which uses 8-m telescopes at the European Southern Observatory.

Dr Antuñano said: “Every six or seven years, we found to space (December 2018) examples of observations when the equatorial clouds had vanished completely, allowing us to see deeper into Jupiter’s University of Leicester students have calculated how many churning atmosphere. These cloud-clearing disturbances left Christmas lights are needed to decorate a house to be visible the equator looking very bright in the infrared, and dark from space. brownish in visible light. These disturbances lasted for 12-18 months, and we saw spectacular examples in 1973, 1979, 1992, 1999 and 2006.” With this pattern, the researchers expected to see events in 1985 and 2013, but although the brownish equatorial colours were apparent, the clouds didn’t clear completely.

Dr Glenn Orton, a Senior Research Scientist at NASA’s Jet Propulsion Laboratory, Pasadena, California, and one of the people responsible for the enormous database of ground- based Jupiter observations used in this study, explained: “As usual, Jupiter is reluctant to give up all its secrets at once. It seems that this six-seven-year pattern isn’t perfect, and sometimes we don’t see a complete cloud-clearing disturbance.” In the 2006 Christmas film Deck the Halls, Danny DeVito's character, Buddy Hall, sets himself a mission: to use Christmas None of these previous equatorial disturbances have been lights to make his house visible from space.

individual planets directly is impossible because of the overwhelming brightness of the host star, the team made calculations to understand the kinds of planets that might be forming in the Taurus star-forming region.

By analysing the data, the team evaluated possible mechanisms that could cause the observed rings and gaps. When the researchers created images of 32 stars surrounded by protoplanetary disks, they found that 12 of them had rings and gaps. These rings and gaps are best explained as traces created by young planets in the making.

Dr Dipierro said: “Our results suggest that gaps and rings are common in protoplanetary discs, as a result of ubiquitous New research discovers 'super-Earths' forming processes in the disc evolution. Although their origin is still debated, our analysis shows that these structures can be around young stars (December 2018) related to the presence of new-born planets, allowing us for the first time to connect the properties of young planets with New research by a team of international astronomers, the statistics.” including a University of Leicester researcher, has found that ‘super-Earths’ and Neptune-sized planets could be forming Moreover, according to the findings, so-called super-Earths or around young stars in much greater numbers than previously Neptune-sized gas planets of up to 20 Earth masses should be thought. the most common. Previous research has suggested that the rings and gaps may be created by ice lines caused by changes in the chemistry of the dust particles across the disc. However, the researchers performed analyses to test this hypothesis and could not find any correlation between ice lines and the patterns of gaps and rings they observed.

Dr Dipierro said: "Analysing the morphologies of gaps and how they relate with the star and disc properties we rule out the idea of ice lines causing the rings and gaps. This strengthens the idea that new-born planets are the main cause for the origin of these structures.” The paper’s lead author, Feng Long of Peking University, Beijing, China said: "This is fascinating because it is the first time that exoplanet statistics, which suggest that super-Earths and are the most

University of Leicester is the UK’s only formal co-investigator on the Juno mission, a connection built by Professor Stan Cowley since the inception of the mission. Members of the Radio and Space Plasma Physics group have been involved in some of the magnetospheric and plasma studies, and with the world-wide campaign of supporting observations with ground- and space-based telescopes.

In 2018, NASA put out a call for interest in Participating Scientist roles, which enable direct data access and a much closer connection with the Juno instrument teams. Dr. Fletcher proposed a joint analysis of Earth-based infrared observations with Juno’s microwave measurements, allowing

September 2019.

Mars Sample Return is going to be one of the biggest scientific projects of the 21st century and the end goal is to bring Mars to Earth……or 500 grams of it!

Scientists want to analyse pristine Mars rock in specialist labs around the World and conduct research that cannot be done by rovers and robots on the surface of the red planet.

Big questions about life on Mars demand high calibre science and equipment and instruments that can guarantee the integrity of such analysis. Identifying signals that give a positive answer to this investigation will be one of the most profound discoveries in the history of humanity.

DWI is an enabling technology to support this scientific endeavour and has been developed at the University of Leicester. And it is students who are making decisions about Professor Martin Barstow to lead UK Space where to study today, that will be the ones who discover if Agency’s Science Programme Advisory there really ever was life on Mars.
